Description

A device for parallel production of sugarcane concentrated juice and sugarcane drinking water with multi-stage membranes

technical field

The utility model relates to a device for producing sugarcane concentrated juice and sugarcane drinking water in parallel with multi-stage membranes, which belongs to the technical field of food processing.

technical background

Sugarcane is not only a raw material for sugar production, but also a fruit unique to subtropical and tropical regions. It is rich in juice, high in sugar content, and has a sweet taste, which is widely loved by people. In addition, sugarcane also has the functions of clearing away heat and detoxification, promoting body fluid and quenching thirst, harmonizing the stomach and relieving vomiting, nourishing yin and moistening dryness, etc. It is a high-quality raw material for the production of beverages. At present, the method of making beverage with sugarcane juice mainly contains two kinds: a kind of is directly squeezed sugarcane juice and is mixed with beverage; Limited by resources and raw materials, it is impossible for beverage processing enterprises to directly extract sugarcane juice to make beverages. At present, most enterprises use concentrated sugarcane juice as raw material to produce sugarcane juice beverages. And in the public report at present, the quality of sugarcane concentrated juice all fails to meet the requirement of high-end customer, traces it to its cause mainly is the problem of production method. As described in the invention patent CN 103330250A, the inventor processed the sugarcane concentrated juice through seven specific technical steps of squeezing the sugarcane, pre-sterilizing and deactivating enzymes, centrifuging to remove particles, enzymatic hydrolysis, ultrafiltration, concentration and sterilization. Though this method can process the sugarcane concentrated juice that concentration is higher, thus helps to save the cost of transportation and storage, but still has many deficiencies: (1) after the sugarcane is squeezed out of the juice, the enzyme is deactivated, and the enzyme deactivation temperature High temperature (95-100°C) can easily cause the decomposition of heat-sensitive substances in sugarcane juice, such as sterols, alkanols and polyphenols, etc., resulting in the loss of nutrients and flavor substances in sugarcane juice; (2) Before ultrafiltration and clarification It needs to go through two cumbersome processes of centrifugation and enzymatic hydrolysis, high energy consumption, and sugarcane juice contains more nutrients needed for microbial growth, coupled with long enzymatic hydrolysis time (60-90min), it is very easy to infect bacteria , will cause sugarcane juice to deteriorate; (3) The temperature of evaporation and concentration is relatively high (the temperature of first-effect evaporation is close to 90°C), and the entrainment of mist in the evaporation process will cause a large loss of aromatic substances in sugarcane juice; (4) The heat load of thermal sterilization will lead to the destruction of flavor substances and nutrients in sugarcane juice, thus affecting the quality of sugarcane juice. There are also many related patent reports, such as: 92108796.9, CN 101985666A, CN 103734838A and CN 104273618A, etc., all of which have more or less similar problems to the above-mentioned invention patents.

Sugarcane contains 70% to 80% of water. In order to reduce the cost of transportation and storage during the processing of concentrated sugarcane juice, part of the water in sugarcane juice must be removed. This water is the raw water in the sugarcane plant, which contains more free radicals that are beneficial to the human body. If this part of water can be fully utilized and processed into drinking water, it will not only enrich the resources of drinking water, but also increase the added value of sugarcane. At present, whether it is a fruit and vegetable juice processing enterprise or a sugar refining enterprise, the water extracted from sugarcane is directly discharged into the waste water pool. Big waste. In order to enrich drinking water resources and increase the added value of the sugarcane industry, in the invention patent CN 103936213A, the inventor successively undergoes techniques such as squeezing out juice, evaporating and condensing, activated carbon (or quartz) treatment, ultrafiltration clarification, reverse osmosis purification, and sterilization. Get bottled drinking water after the step. Although this method can make full use of the water in the sugarcane, the inventor has not mentioned the processing mode of the remaining sugarcane juice after extracting the water in the sugarcane, if only the water in the sugarcane is extracted, and the sugarcane juice The effective components in it are not utilized, which is a great waste of sugarcane resources, almost killing chickens and taking eggs; and the inventor adopts ozone method, ultraviolet radiation method or chlorine dioxide method to sterilize drinking water, these sterilization methods will not only destroy Some free radicals in sugarcane water are beneficial to the human body, and a small amount of fungicides left in the water will also have certain side effects on the human body. In the invention patent CN 101798148A, the inventor used the first-effect and second-effect condensed water of the sugarcane sugar factory as raw materials, and obtained sugarcane drinking water after ultrafiltration, nanofiltration clarification, reverse osmosis purification and sterilization. . Although this method extracts the water in the sugarcane and processes it into drinking water, it can extract the sugar in the sugarcane at the same time, but the condensed water of the first and second effects comes from the clarified sugarcane juice, and the sugarcane juice clarification process Many chemical reagents are added as clarifiers, such as: lime, SO ₂ , phosphoric acid and polyacrylamide, etc. The water obtained in this way will inevitably destroy the free radicals in the sugarcane water that are beneficial to the human body, and even leave a small amount that is harmful to the human body. The chemical substance, especially the monomer (acrylic acid) used to synthesize polyacrylamide, is a carcinogen.

Therefore, to provide a processing method and device for sugarcane concentrated juice, the product quality is better, the production efficiency is higher, the cost is lower, and the water extracted from the sugarcane can be fully utilized to process it into high-quality drinking water. It is necessary to increase the added value of sugarcane.
