Description

The invention relates to the chemical industry and can be used to obtain extracts of natural biologically active substances (BAS) and other products from multicomposite mixtures of ingredients of aboveground biomass of plant materials.

A known method of processing berries of chokeberry by crushing them and subsequent extraction of biologically active substances with ethanol-water mixtures of a certain composition at specific hydromodule and system temperature [1].

However, at the same time, the share of plant biomass used in the economic turnover is low, the concentration of recoverable components in the extracts obtained, as well as technical, economic and quality indicators are small, material and energy costs are significant.

There are methods and modes of extracting biologically active substances from the bark and fruits of Viburnum vulgaris, suitable for other wild plants. However, while the remaining components of the biomass are practically not utilized, although, as was established in recent years [2–4], the same biologically active substances are also present in flowers, foliage, and non-lignified shoots. As a result, a significant part of the valuable natural raw materials is not disposed of, the degree of development of forest gifts remains extremely low.

Closest to the proposed is a method of processing viburnum vulgaris by individual extraction of biologically active substances from flowers, berries, foliage, non-lignified shoots and plant bark containing the same biologically active substances [5]. It was also established that for all types of raw materials during extraction, the most significant are the temperature of the system, the ethanol content in the water-alcohol solvent and the hydromodule, and their numerical values corresponding to the optimal extraction are close.

The disadvantage of this method is that the extraction of biologically active substances from plant raw materials of common viburnum is carried out sequentially from all the ingredients of the aboveground biomass, as a result of which its duration is very long, or if the processing of individual ingredients is carried out in parallel, the hardware-technological scheme becomes unreasonably cumbersome. In addition, with this method of utilization of plant materials, the collection, sorting, storage and grinding of biomass ingredients must also be carried out separately.

Known hardware-technological schemes (ATS) for obtaining extracts of biologically active substances from plant materials, consisting of three main stages: the first is the collection and rejection of individual biomass ingredients, their sorting, freezing and storage; the second - crushing of the solid phase and extraction of certain ingredients from it; and the third - recycling [6, 7] of production.

So, the hardware-technological scheme for processing the fruits of chokeberry [6] consists of a block for the reception, processing, packaging and storage of raw materials, crushing and extraction compartments, and a unit for processing solid waste. The technological scheme contains a fruit processing unit, a storage chamber, a knife chopper, a mixer, a packaging unit, a heating chamber, a screw separator, a blending vat, a filling and packaging unit, an extraction unit, a vacuum filter, a drying unit, a press, an evaporation unit, a collector, a pump , heat exchanger, alcohol trap. The technological scheme works according to the following principle. Vegetable raw materials are delivered by road to the preparatory department, fruit processing operations are carried out in the berry processing unit, where they are weighed, sorted, and foreign particles, spoiled berries and other impurities are removed. Then the bulk of the raw material, with the exception of that processed immediately after delivery, is packed in plastic bags and placed in wooden, cardboard boxes (boxes) stored in a refrigerator at low temperatures.

When processing fruits according to the option of obtaining juice, the fruits stored at negative temperatures enter the heating chamber, where they are kept. After heating, the raw materials are sent to a screw separator, in which the fruits are crushed and divided into liquid (juice) and solid (pulp) phases. The juice is pumped into the blending container, where the components necessary for the recipe are simultaneously supplied, if necessary, previously crushed in an impact-splitting mill or in a screw crusher. The obtained blended juice is pumped to the bottling and packaging unit, from where it is sold as a finished product.

The pulp is sent to the extraction unit, where in the active hydrodynamic mode, the biologically active substance is extracted from it with a water-alcohol mixture. The extractant from the collector is fed to the extraction unit by a pump through a heat exchanger designed to maintain a constant temperature of the system during extraction. Then the mixture is sent to a vacuum filter. The liquid, enriched with biologically active substances, after settling and filtering with a pump, is pumped to a collection tank, from where it can immediately be sent to bottling, packaging and sale, or through a heat exchanger it is sent to an evaporator, where it is evaporated and then poured into a collection tank, from where it is sent to bottling, packaging and sales.

Ethanol vapors formed during boiling are trapped in an alcohol trap, and condensate is pumped to a collection of water-ethanol mixtures for reuse.

The solid wet post-extraction meal is sent to the drying unit, and then to the press and, through the packaging unit, for sale.

When processing fruits with mashed potatoes, that is, without phase separation, the raw materials from the storage chamber immediately go to a knife chopper. The crushed mass of fruits is fed into the mixer, into which the ingredients necessary for the recipe are also added, and then, through the packaging unit, it is sold. Frozen fruit is also available.

The circuit has the following disadvantages. Firstly, it is suitable only for fruit processing, and its second significant drawback is the need to concentrate the extracts obtained, which inevitably entails the complication of the hardware-technological scheme, an increase in material and energy costs, a decrease in the quality of products and economic indicators.

Closest to the claimed is a hardware-technological scheme for obtaining extracts enriched with iridoids from viburnum bark ordinary [7], including a sorting, refrigerating cabinet, knife chopper, berry heating unit, screw chopper, container, centrifugal pump, heat exchanger-heater, extractor, vacuum filter, convection dryer, centrifuge, mill. According to this technological scheme, raw materials are delivered by road to the preparatory department of the workshop, where they are weighed, sorted, and foreign particles and contaminants are removed. Raw materials are dried in a dark well-ventilated area, crushed in a knife chopper. Then the bulk of the raw materials are packed in rag bags and placed in wooden, cardboard or plastic boxes (boxes) and, if necessary, stored in room conditions.

A batch of bark particles is loaded into an extractor equipped with a stirrer. An extractant preheated in a heat exchanger is pumped from a tank by a centrifugal pump. The temperature of the system is maintained constant during the process of extracting biologically active substances from plant materials that takes place here in the active hydrodynamic mode.

Upon completion of extraction, the system is sent to a vacuum filter for separation into a filtrate enriched with biologically active substances, and the solid residue is a post-extraction meal, which is washed in a vacuum filter and dried in a drum dryer to remove ethanol.

Liquid extract as a finished product is sent to bottling, packaging and subsequent sale. Meal is crushed in a grinder and packaged for further use as an additive enriched with dietary fiber.

A common drawback of the schemes discussed above is that they are either bulky, since the processing of individual biomass ingredients is carried out in parallel in separate devices, which complicates the scheme, or the extraction of biologically active substances from individual components is carried out sequentially, as a result of which the total processing time sharply increases.

Studies have been carried out that show the promise of creating methods and technologies for the joint processing of multicomposite mixtures of ingredients of aboveground biomass of plants with a reduction in material and energy costs, an increase in economic and quality indicators of production, and a simplification of the hardware and technological scheme and a reduction in processing time.

The objective of the invention is to increase the degree of use of natural plant materials, expanding the range of products obtained containing biologically active substances, simplifying the technological scheme of production and reducing the duration of the process.

The technical result consists in increasing the use of aboveground biomass of plant materials and obtaining a variety of products: concentrated extracts of biologically active substances from multicomposite materials by multi-stage (3-fold) extraction with the same solvent from fresh portions (lots) of biomass, mashed potatoes, fruit juice, fruit powder for confectionery; simplification of the hardware-technological scheme of production by reducing the number and duration of operations and reducing the number of devices; increasing the use of renewable plant materials by increasing the number of processed ingredients.

The specified technical result is achieved by the fact that in the method of complex processing of plant materials, including biomass preparation, sorting, cooling, heating, grinding, extraction and isolation of the final product, a multicomposite mixture of jointly processed flowers, fruits, leaves, non-lignified shoots and bark of vegetable raw materials, the extraction of raw materials is carried out in three stages with the same solvent, sequentially pumped through the extractors of the first, second and third dullness at the same hydromodule in all extractors, and at the second and third steps, the masses of portions of fresh raw solid feed introduced into the extractors at a given hydromodule are determined taking into account solvent losses at the previous extraction step, the obtained extract is processed, and meal from three extractors is sent for additional extraction to obtain an extract with a low content of biologically active substances, which goes to the subsequent concentrated, and meal, which is dried, and grinding and processing to produce food or feed additives.

The technological scheme of complex processing of plant raw materials includes a sorting, refrigerating cabinet, a heating chamber, a screw chopper connected to a puree filling and packaging unit, a screw press connected to a centrifuge and a juice container, a vibroextractor, heat exchangers, a vacuum filter, a convection dryer, a chopper, the circuit contains three sequentially installed vibroextractors connected to a screw press, and an extractor for re-extraction of biologically active substances from the meal, unloading many of vibroextractors.

The extraction of multicomposite raw materials is carried out in three stages, on each of which the same solvent sequentially pumped from one stage to another interacts in all three extractors with fresh portions of the multicomposite mixture at the same ratio of the mass of the solvent and plant biomass equal to the hydromodule. After separation of the concentrated extract, meal from the extractors of the first, second and third stages, as well as pulp after separation of the juice, are sent for extraction to obtain a diluted extract and its subsequent concentration. The spent mixture of meal and pulp is used to obtain powder.

The technological scheme of complex processing of plant materials is suitable for:

- concentrated extracts of biologically active substances from a multicomposite mixture of plant materials (flowers, berries, leaves, non-lignified shoots and bark);

- fruit powder for various confectionery products;

- puree from fresh or frozen berries;

- fruit juice.

The use of a multicomposite mixture of collectively collected, stored, crushed and extracted ingredients of aboveground biomass (flowers, fruits, leaves, non-lignified shoots, bark) as a raw material for obtaining concentrated extracts of biologically active substances and carrying out multi-stage extraction of biologically active substances instead of a single-stage one can reduce or eliminate the operations of collection, sorting, storage, crushing of raw materials and concentration of extracts, leads to lower material and energy costs, the growth of economic and quality indicators.

Figure 1 presents the proposed hardware-technological scheme of complex processing of plant materials.

The hardware and technological scheme for the complex processing of plant materials consists of a point for receiving and sorting raw materials 1, a refrigerating cabinet 2, a heating chamber 3, a screw chopper 4, a screw press 5. The refrigerating cabinet 2 is also connected to a screw chopper 4 and further to the filling and packing unit 6 fruit puree. The screw press 5 is connected to three sequentially installed vibroextractors: the first stage 7, the second stage 8 and the third stage 9, which are connected to the extractor 10 for re-extraction of the solid phase, unloaded from the vibroextractors 7, 8, 9 and the pulp extracted after squeezing the juice from the screw press 5.

The technological scheme includes heat exchangers 11 to maintain a constant temperature of the system, vacuum filters 12 connected to vibroextractors 7, 8, 9 and extractor 10, centrifugal pumps 13 connected to heat exchangers 11 and containers for solvent 14. Extractor 10 is connected to capacity 14, a convective dryer 15 and a knife chopper 16. The screw press 5 is also connected to a centrifuge 17 and then to the fruit juice filling and packaging unit 18 (fruit juice production line).

The method of complex processing of plant materials in the case of using composite materials is as follows.

Plant materials: flowers, fruits, leaves, non-lignified shoots and bark of plant materials are fed to the stage of biomass preparation at the point of reception and sorting of raw materials 1, where sorting and rejection takes place. Further, the raw material goes for cooling to the walk-in closet 2. The necessary mass of raw materials going for processing is heated in the heating chamber 3 and then fed to the screw shredder 4 for grinding. Then, extractors 7 - of the first, 8 - second and 9 - third stages are extracted A biologically active substance from the portions of fresh raw materials loaded here with the same solvent pumped sequentially through devices 7, 8 and 9. At all stages of extraction, the ratio of the masses of solvent and solid phase supplied here from the screw press 5 is supported by constant and equal to the hydraulic module. The solvent heated in the heat exchanger 11 (water-ethanol mixture) is supplied from the tank 14 by a centrifugal pump 13 to the vibroextractor 7. The heterogeneous system obtained in the first stage in the vacuum filter 12 is separated into a filtrate and a moist post-extraction meal. The concentrated extract from apparatus 9 goes to the packaging.

The post-extraction meal from the extractors 7, 8 and 9 is sent for re-extraction to the extractor 10, where pulp from the screw press 5 obtained after separation of the fruit juice can be added.

Extraction of the extract from the post-extraction meal after three extraction stages from the extractors 7, 8 and 9 is carried out in the extractor 10 with a solvent heated in the heat exchanger 11. The extract obtained from the extractor 10 with a low concentration of biologically active substances is evaporated after separation on the vacuum filter 12. The resulting meal from the extractor 10 is collected in a container 14, then sent for drying to a convective dryer 15, crushed in a knife chopper 16 to obtain a food or feed additive, suitable for preparing various culinary products or feed.

The technological scheme is suitable for processing chilled or fresh fruits to produce fruit puree, when the fruits, having passed the collection and sorting point 1, are cooled depending on the season in the refrigerator 2 and then, if necessary, heated in the heating chamber 3, or, bypassing the cooling and storage operations , warming up immediately after calibration 1, enter the screw shredder 4, then go to the bottling and preparation unit of puree 6. The resulting residues from the screw shredder 4 are sent to the screw press 5 and added to the total mass astitelnogo raw materials.

Upon receipt of fruit juice, the mass of fruits after the screw chopper 4 enters the screw press 5, then the suspension goes to a centrifuge 17 and to the spill and packaging unit of fruit juice 18, and the pulp is sent to the extractor 10.

Below are some examples of the many possible options for processing multicomposite mixtures of plant biomass to produce various products.

Example 1

Obtaining extracts of biologically active substances enriched in iridoids from a polycopositive mixture of ingredients of the aboveground biomass of viburnum vulgaris.

As a raw material, a multicomposite mixture of ingredients of the aerial parts of the common viburnum is used, the mass ratio of the components of which, established experimentally, was - berries: leaves: shoots: bark = 0.56: 0.19: 0.05: 0.20. Its absolutely dry mass equal to 0.68 kg (all the masses of solid processed raw materials indicated in the examples are given in terms of absolutely dry), after rejecting at the collection and sorting point 1, it is crushed in a screw grinder 4.

Then, a part of it, equal to 0.25 kg, selected by quartration, is loaded into the vibroextractor of the first stage 7. Here, under optimal conditions, it is hydromodule 15 and a temperature of 40 ° C with a water-alcohol mixture with an ethanol content of 90% vol. Iridoid extraction is in progress. The mass of solvent supplied to the vibroextractor of the first stage 7 is 3.75 kg. At the end of the first stage of extraction in the vacuum filter 12 of the first stage, the heterogeneous system is divided into a wet post-extraction meal weighing 1.17 kg and 3.45 kg of filtrate, which is sent to a vibroextractor of the second stage 8. 0.23 kg of fresh crushed multicomposite mixture are introduced into the same . At the end of the second stage of iridoid extraction, the yield of the meal after extraction is 1.17 kg, and the extractant is 3.13 kg. Next, the filtrate enters the vibroextractor of the third degree 9.

Finally, after the third extraction stage, where 0.20 kg of freshly crushed multicomposite raw materials are processed, the mass of the discharged meal is 1.24 kg, of the extract - 2.82 kg.

The phase contact at each of the three stages lasts 20 minutes.

The concentrated extract of iridoids after the vacuum filter 12 of the third stage is discharged and used in the production of medicines, various drinks and in other areas.

After extraction meal from all three stages of extraction of biologically active substances is reloaded into the apparatus 10, where it is re-extracted with the aim of utilizing the remaining biologically active substances. The resulting extract is either concentrated by evaporation or used for other purposes. The solid wet residue after vacuum filters 12 is dried in a convective dryer 15, crushed in a knife chopper 16 and used as a food or feed additive and other directions.

The values of various parameters characterizing the process of multistage extraction of iridoids from multicomposite mixtures of ingredients of aboveground viburnum biomass are presented in table 1.

As you can see, the yield of the concentrated extract of iridoids from 3.75 kg of solvent is 2.82 kg, that is, 75% of the original. The content of iridoids in the extract after the first stage of extraction is 4.18% a.s., after the second - 7.11% a.s., after the third - 16.84% a.s., therefore the proposed process scheme allows to obtain extracts with an iridoid content of 3.8 times higher than with a single-stage.

Example 2

Multicomposite raw materials of the aerial parts of common viburnum are used to extract extractive substances from a multicomposite mixture. The optimal values of the operating parameters in this case are different - the temperature of the system is 60 ° C, and the concentration of ethanol in the solvent is 60% vol., Hydromodule 15.

As in example 1, at all stages of a three-stage extraction plant, the same solvent, sequentially pumped from one extractor to another, is in contact with fresh batches of a multicomposite mixture. The ratio of solvent mass to absolutely dry mass of plant material in all extractors in accordance with the hydronic module is 15. The values of the extraction indicators are presented in table 2.

As you can see, the content of extractives in the stages of extraction are equal to:

- after vibroextractor 7 of the first stage of 45.31% and.with.,

- vibroextractor 8 of the second stage 74.01% a.s.

- vibroextractor 9 of the third stage of 137.98% a.s., i.e., the transition from a single-stage process scheme to a three-stage one allows changing the degree of extraction of EV by 3.1 times. The yield of solvent enriched in extractive substances, as in Example 1, is 2.82 kg (75% of the initial).

The directions of the use of concentrates, as well as the disposal of waste, are similar to example 1.

Example 3

The third example is a processing option of the same as in examples 1 and 2, a multicomposite mixture with the receipt of several products.

From a batch of a multicomposite mixture of ingredients of aboveground biomass of viburnum with an ordinary weight of 4.00 kg, consisting of 2.24 kg of fruits (absolute humidity 490%), 0.76 kg of leaves (absolute humidity 250%), 0.20 kg of non-lignified shoots ( absolute humidity 160%) and 0.804 kg of bark (absolute humidity 100%) after sorting 1 is divided into berries (weight 2.24 kg, absolute humidity 490%) and multicomposite mixture (1.76 kg). The berry to increase subsequent juice separation is cooled to a temperature of minus -20 ° C and stored in a refrigerator 2. Then the fruits are heated in a heating chamber 3 to a temperature of 20 ° C and crushed in a screw press 5 with separation into a solid phase weighing 0.59 kg and unclarified juice weighing 1.65 kg, which, if necessary, is clarified in a centrifuge 17, after which it is sent for use, or is bottled and packaged in the fruit juice filling and packaging unit 18.

The remaining 1.76 kg of the multicomposite mixture is crushed in a screw press 5. A batch of 0.64 kg, selected by quarting, and 3.9 kg of solvent are loaded into the vibroextractor of the first stage 7. After the extraction is completed, the solvent is pumped to the vibroextractor of the second stage 8 and further into the vibroextractor of the third stage 9. The masses of the fresh multicomposite mixture loaded into the apparatuses 8 and 9 are determined by the hydraulic module (0.59 kg and 0.51 kg, respectively). The extraction of iridoids is carried out under conditions similar to example 1. The ratio of the masses of solvent and solid phase in all extractors is 15.

The values of the parameters characterizing the conditions of processing of raw materials by pressing berries and extraction, the results obtained are presented in table 3.

The scheme for the disposal of beet pulp after juice separation and post-extraction meal is similar to example 1.

As can be seen, in this case, the content of iridoids in the extract after the first stage of extraction is 2.20% a.s.with., After the second - 3.67% a.s.w., after the third - 7.87% a. ss, therefore, with this variant of processing viburnum biomass in parallel with obtaining juice, the product is also a concentrated extract, the content of iridoids in which is 3.6 times higher compared to that obtained with single-stage extraction. The yield of the extract, as in the previous examples, is 75%.

The obtained results of the extraction of biologically active substances show that polycomposites from fruits, leaves, bark, and non-lignified shoots of plant materials are promising raw materials for obtaining products enriched with biologically active substances; creating functional, tonic, alcoholic and other drinks; food additives based on extracts of biologically active substances and pulp obtained in the production of juices; food and feed additives from dried and crushed post-extraction meal.

It has been experimentally determined that multicomposite mixtures of ingredients of aboveground biomass - annually renewable components of plant materials - are a forest product rich in biologically active substances. The additional volume of extracts from multicomposite mixtures (leaves, shoots, bark) is comparable to that of berries, that is, the total yield of extracts from multicomponent plant mixtures is approximately 1.3 times higher than that obtained from fruits.
