Description

Food crushing elevator

technical field

The invention relates to a food crushing hoist.

Background technique

At present, in the industry, the first process of producing energy bars and sugar row foods is to put the block-shaped raw materials formed by mixing cereal materials with syrup into a single-roller extrusion machine to extrude them into continuous long rows of raw materials, and then The conveyor line is transported to the subsequent production equipment to complete the pouring, forming, cutting and other processes.

Since the bulk raw materials of the above-mentioned energy bars and sugar row foods are characterized by high viscosity, different sizes, and poor uniformity, if they are placed in a single-roller extruder without crushing, the processing efficiency will be very high. Low, and often there will be uneven thickness in rows and loose sections, which will affect the quality of subsequent products. For this reason, the current practice in the industry is to stir the raw materials with conventional mixing equipment, and then transfer them to the single-group roller extruder. However, in practice, the following problems are exposed:

1) Conventional mixing equipment is mostly screw mixing equipment, which does not have a good crushing effect on energy bars and sugar row raw materials with high viscosity, and makes the raw materials easier to condense into agglomerates after repeated stirring treatment;

2) After the raw materials are stirred, they cannot be transported to the single-set roller extruder in time, and often during the standing or conveying process, the raw materials will gather and agglomerate again, resulting in repeated inhomogeneity.

Therefore, there is an urgent need in the industry to design special equipment that has a good crushing effect on energy bars and candied foods, and can immediately feed raw materials into a single-group roller extruder after crushing.

Contents of the invention

The purpose of the present invention is to provide a food crushing hoist, which is specially designed for crushing energy bars and sugar row food raw materials and then immediately feeding them into a single-group roller extrusion machine, with good crushing effect and high working efficiency. It helps to improve the subsequent food processing efficiency and molding quality.

The technical solution of the present invention is: a food grinding hoist, which is characterized in that it includes a grinding mechanism and a lifting mechanism. The double-roller crushing mechanism includes a box body, two roller shafts pivotally arranged in the box body and arranged up and down, and a roller-driven reduction motor respectively connected to drive the rotation of the two roller shafts. There are several roller shafts along the length direction. Radial hammer; there is a feeding port on the box body, and the end of the circulating transmission belt of the crushing mechanism extends into the box body through the feeding port, and the bottom of the box body is provided with a discharge port; the lifting mechanism includes a lifting mechanism bracket and a setting The hoisting mechanism circulation transmission belt and its driving mechanism are arranged obliquely on it. The lower end of the hoisting mechanism circulation transmission belt is located below the discharge port at the bottom of the box body, and the hoisting mechanism bracket is also provided with a belt spanning the hoisting mechanism circulation transmission belt. The screw material distributing mechanism, the screw material distributing mechanism includes vertical plates arranged on both sides of the hoisting mechanism circulating transmission belt, a material distributing screw pivotally arranged on the vertical plate, and a screw drive reduction motor connected to drive the material distributing screw to rotate.

It needs to be clarified that whether it is the driving mechanism of the circulating transmission belt of the crushing mechanism or the circulating transmission belt of the lifting mechanism in the present invention, it means that the driving mechanism in the synchronous pulley assembly is conventionally driven by the synchronous pulley assembly and the connection for tensioning the belt. The drive mechanism formed by the pulley drive motor is well known by those skilled in the industry, and the present invention will not describe it in detail.

Further, in the present invention, the roller shaft is provided with several radial hammer groups along the length direction, and each radial hammer group is composed of two or more radial hammers distributed evenly along the circumference of the roller shaft, and The radial hammers on the upper and lower rollers are distributed alternately. In the present invention, the radial hammers on the two roller shafts are mainly used to crush energy bars and sugar row food raw materials (hereinafter referred to as food raw materials), and the large raw materials are hit and crushed into small pieces and more uniform raw material. The radial hammers on the upper and lower rollers are staggered to crush the raw materials alternately and continuously, which obviously can greatly improve the crushing effect.

Further, the distributing screw in the present invention includes a rod body and two sets of helical threads arranged on the outer surface of the rod body, which are symmetrical and opposite to the center of the rod body, and these two sets of helical threads are integrated at the center of the rod body. The function of the distributing screw is to make the food raw materials falling on the circulating transmission belt of the lifting mechanism better evenly spread out, rather than all gathered in the center. The design of two sets of reverse helical patterns can obviously give full play to the advantages of this kind of material distribution, ensuring that the raw materials are spread more evenly on the belt.

Further, the pulverizing mechanism in the present invention also includes two baffles fixed on the pulverizing mechanism bracket and located on both sides of the pulverizing mechanism circulating transmission belt, which is arranged on the pulverizing mechanism bracket and abuts against the bottom of the pulverizing mechanism circulating transmission belt. Several crushing mechanism scrapers and several crushing mechanism material receiving trays fixed on the crushing mechanism support and located below the crushing mechanism circulation transmission belt. The design of the baffle is obviously to prevent the food raw materials transported on the circulating transmission belt of the crushing mechanism from splashing around and polluting the working environment. The function of the scraper of the crushing mechanism is to scrape off the food raw materials adhered to the bottom of the circulating transmission belt of the crushing mechanism. On the one hand, more raw materials can fall on the circulating transmission belt of the lifting mechanism below, and on the other hand, it can clean the circulating transmission belt of the crushing mechanism , and recover raw materials. The role of the receiving tray of the crushing mechanism is to cooperate with the scraper of the crushing mechanism to recover the scraped food raw materials (including those that fall off automatically under the action of gravity) that adhere to the circulating transmission belt of the crushing mechanism to avoid waste.

Further, the lifting mechanism in the present invention also includes a plexiglass cover fixed on the support of the lifting mechanism and covered on the periphery of the circulating transmission belt of the lifting mechanism, and the plexiglass cover is opened with a hole opposite to the discharge port of the box. the feed port. The design of the plexiglass cover also prevents the food raw materials from spilling when they are conveyed on the circulating conveyor belt of the lifting mechanism, and the relative design of the discharge port and the feeding port ensures that the food raw materials will not flow to the surroundings during the connection process of the crushing mechanism and the lifting mechanism. spill out.

Furthermore, the screw material distributing mechanism in the present invention is located in the material receiving port. In principle, the screw powder mechanism only needs to be designed on the transmission path of the circulating transmission belt of the lifting mechanism to implement material distribution. However, since the food raw materials pulverized by the double-roller crushing mechanism first fall on the circulating transmission belt of the lifting mechanism through the feeding port, the food raw materials at the inner side of the feeding port are the source of accumulation, so we separate the materials by the screw Mechanism design can better distribute food raw materials in the feeding port.

Further, the lifting mechanism in the present invention also includes several lifting mechanism scrapers fixed on the upper part of the lifting mechanism bracket and against the bottom of the lifting mechanism circulating transmission belt, and several lifting mechanism scrapers fixed on the lifting mechanism bracket and located below the lifting mechanism circulating transmission belt. Lifting mechanism receiving tray. Similarly, the function of the lifting mechanism scraper is to scrape off the food raw materials adhered to the bottom of the circulating transmission belt of the lifting mechanism. On the one hand, more raw materials can enter the single-roller extrusion machine, and on the other hand, it can clean the circulating transmission belt of the crushing mechanism. and recycle raw materials. The role of the material receiving tray of the lifting mechanism is to cooperate with the scraper of the lifting mechanism to recover the scraped food raw materials (including those that fall off automatically under the action of gravity) that adhere to the circulating transmission belt of the lifting mechanism to avoid waste.

Furthermore, the crushing mechanism support and the lifting mechanism support in the present invention are connected into one body by connecting rods, which can further strengthen the connection between the crushing mechanism and the lifting mechanism, and improve the overall structural stability of the present invention.

Further, in the present invention, the bottom of the crushing mechanism bracket is provided with the crushing mechanism support feet and the crushing mechanism support rollers, and the bottom of the lifting mechanism support is provided with the lifting mechanism support feet and the lifting mechanism support rollers.

The working principle of the present invention is as follows:

The present invention is mainly used in the production process of energy bars and candied foods. When used specifically, it is placed on the side of the single-roll extruder, and the top hopper of the single-roll extruder is ensured to be located exactly in the present invention. The lifting mechanism circulates under the high-end of the belt to facilitate material pick-up.

Initially, the food raw materials are conveyed by the circular transmission belt of the crushing mechanism. The food raw materials enter the box of the double-roller crushing mechanism at the end of the circular transmission belt of the crushing mechanism. The discharge port at the bottom of the body falls, and falls to the circulating transmission belt of the lifting mechanism through the material receiving port on the plexiglass cover, and is evenly spread on the surface of the circulating transmission belt of the lifting mechanism under the treatment of the screw material distribution mechanism to convey to the high end.

Finally, the food raw materials are lifted to the high end by the circulating transmission belt of the lifting mechanism, and then fall down, and enter the single-roller extruder to be extruded into long rows.

The advantages of the present invention are:

The invention is specially designed for crushing energy bars and sugar row food raw materials and then immediately feeding them into a single group of roller extruders. The crushing effect is good, the work efficiency is high, and it is helpful to improve the subsequent food processing efficiency and molding quality. , its technical details and advantages are as follows:

The crushing is highly targeted and the effect is good. Especially for food raw materials with high viscosity, it avoids the disadvantages of conventional screw stirring equipment that the more sticky it is, the more sticky it is, and the stirring is not broken. In addition, the radial hammers on the upper and lower rollers are staggered to crush the raw materials alternately and continuously, which obviously can better improve the crushing effect.

2) In the present invention, the lifting mechanism and the crushing mechanism are well connected, so that the food raw materials crushed by the crushing mechanism can be directly lifted to a high place by the lifting mechanism, and finally fall into the single-group roller extruder. Compared with the prior art, there is no intermediate manual transfer process, which can effectively prevent the phenomenon of agglomeration of raw materials after standing still.

3) In the present invention, a screw material distributing mechanism across the circulating transmission belt of the lifting mechanism is further designed. The function of this mechanism is to enable the food raw materials falling on the circulating transmission belt of the lifting mechanism to spread evenly and evenly, instead of All gathered in the center. The design of the two sets of reverse helical patterns on the material distribution screw can obviously give full play to the advantages of this material distribution, ensuring that the raw materials are spread more evenly on the belt, which is more conducive to the extrusion molding of the single-roll extruder.
