Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a feeding device for food materials. Background Art

[0002] With the improvement of people's living standards, meat and fish can no longer meet everyone's needs. Whole grains and coarse grains have become more and more popular. In order to meet everyone's needs, various whole grains and coarse grain powders have emerged. Whole grain powder is a product made by mixing and crushing various grains in proportion after baking and maturing, so it can be eaten directly, which is very convenient and popular.

[0003] Multi-grain flour is made by baking carefully selected grains and cereals at low temperatures, strictly controlling the baking temperature and time, cooking the raw materials, and then crushing them. The crushed materials are then proportioned and canned to form a finished multi-grain flour product that can be eaten by brewing with boiling water.

[0004] Specifically, the production of grain powder generally includes four steps: raw material selection, drying, ripening and canning. Raw material selection refers to selecting grain raw materials that meet national standards, removing impurities and incomplete particles, and cleaning them; ripening is divided into different ripening processes according to different materials, including materials that need to be puffed, referred to as puffed materials (A materials) and microwave-ripened materials, referred to as microwave materials (B materials). Puffed materials are grains such as corn, mung beans, red beans, coix seeds, quinoa, wheat bran, millet, etc.; microwave materials are soybeans and peanuts; the puffed materials are first weighed, mixed and crushed in proportion, and the crushed ingredients are added with water to adjust the humidity and then enter the puffing machine for puffing and granulation, and then sent to the oven for baking and crushing; the microwave material is baked, dehydrated, disinfected and sterilized in a low-temperature baking machine, and then ultra-finely crushed: canning is to mix and stir material A, material B and other trace amounts of material C and material D, and then send them to a microwave sterilizer for high-temperature sterilization, and then send them to the packaging workshop for weighing and packaging.

[0005] Among them, raw materials that need to be puffed, such as corn, mung bean, red bean, coix seed, quinoa, wheat bran, millet, etc., need to be mixed evenly before crushing. The mixing method is to lay various materials layer by layer in the transfer vehicle according to the proportion, and then insert the vacuum suction port of the mixing tank into the material, and complete the mixing during the vacuum suction process. The material entering the mixing tank is transferred to the side of the crusher, and the mixed material is added to the crusher for crushing; the existing problems are: the mixed material in the mixing tank is manually scooped into the crusher, or the vacuum pump is manually controlled to draw the mixed material into the hopper of the crusher. The operator needs to keep a close eye on the material situation in the hopper at all times. There must not be an empty warehouse situation that causes the crusher to run idle without material, and there must not be too much material in the hopper to cause overflow or compaction blockage. Therefore, manual energy needs to be highly concentrated and prone to fatigue. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a feeding device for food materials.

[0007] The purpose of the utility model is implemented by the following technical scheme: a feeding device for food materials, comprising a mixing tank, a crusher, a frame, a vacuum feeder, a hopper and a controller, wherein the hopper is fixedly installed on the upper part of the inlet of the crusher, the storage hopper of the vacuum feeder is fixedly connected to the frame, and the storage hopper of the vacuum feeder is arranged on the upper part of the hopper; the suction pipe inlet of the vacuum feeder is inserted in the mixing tank, and the discharge port outlet of the storage hopper of the vacuum feeder is arranged in the hopper;

[0022] Embodiment 1:

[0023] A feeding device for food materials, comprising a mixing tank 1, a crusher 2, a frame 3, a vacuum feeder 4, a hopper 5 and a controller 6, wherein the hopper 5 is fixedly mounted on the upper part of the inlet of the crusher 2, a storage hopper 41 of the vacuum feeder 4 is fixedly connected to the frame 3, and the storage hopper 41 of the vacuum feeder 4 is arranged on the upper part of the hopper 5; an inlet of a suction pipe 42 of the vacuum feeder 4 is inserted in the mixing tank 1, and an outlet of the storage hopper 41 of the vacuum feeder 4 is arranged in the hopper 5;

[0024] A material level meter (not shown in the figure) is provided on the inner wall of the hopper 5 , and the material level meter is connected to the input end of the controller 6 by signal, and the output end of the controller 6 is connected to the air pump 43 of the vacuum feeder 4 by signal.

[0025] A filter cloth 7 is sleeved on the outer side of the discharge port of the storage hopper 41 of the vacuum feeder 4, and the filter cloth 7 covers the upper part of the hopper 5 to ensure that the expanded material does not fly during the discharge process.

[0026] The frame 3 is a liftable frame 3, including a column 31 and a support rod 32 arranged on the column 31, one end of the support rod 32 is slidably connected to the column 31, and the other end of the support rod 32 is fixedly connected to the storage hopper 41 of the vacuum loader 4, and the support rod 32 is driven by a driving device 33 to slide up and down on the column 31; the driving device 33 is connected to the output end signal of the controller 6.

[0027] In this embodiment, the driving device 33 includes a driving motor 331, a fixed pulley 332 and a traction rope 333. The fixed pulley is rotatably arranged on the upper part of the column 31. One end of the traction rope is fixedly connected to the column 31. The other end of the traction rope 333 passes around the fixed pulley 332 and is fixedly connected to the output shaft of the driving motor 331. The driving motor 331 is connected to the output end signal of the controller 6.

[0028] Directions:

[0029] Before starting, the driving motor 331 drives the storage hopper 41 of the vacuum feeder 4 to reset, that is, the outlet of the discharge pipe of the storage hopper 41 is located at the lower part of the hopper to prevent the expanded material from falling from a high altitude and causing the expanded material powder after crushing to spread;

[0030] When starting, the expanded material raw materials (corn, mung bean, red bean, coix seed, quinoa, wheat bran, millet) are first weighed, mixed and then sent to the mixing tank 1, the crusher 2 and the vacuum feeding device are started, and the expanded material raw materials are sucked into the storage hopper 41 through the suction pipe 42 of the vacuum feeding machine 4, and then fall into the hopper at the bottom, and the hopper is sent to the crusher 2 for crushing;

[0031] The material level meter monitors the material level in the hopper in real time and feeds back to the controller 6. The controller 6 adjusts the operation of the drive motor 331 in real time according to the material level value fed back by the material level meter to achieve the rise and fall of the storage hopper 41 of the vacuum feeder 4, and ensure that there is a certain distance between the outlet of the discharge pipe of the storage hopper 41 and the material in the hopper;

[0032] In addition, when the material level exceeds the upper limit, the controller 6 controls the air pump 43 of the vacuum feeder 4 to stop to prevent the expanded material from being fed beyond the hopper and causing overflow; until the material level is lower than the lower limit, the air pump 43 is restarted to ensure that there is always expanded material in the hopper, on the one hand to prevent the crusher 2 from idling without material, and on the other hand to prevent the powder in the crusher 2 from escaping.

[0033] The power of the air pump 43 in this embodiment is adjusted to a level that is substantially consistent with the feed speed and the crushing efficiency. Therefore, the air pump 43 works continuously during normal operation. Setting a level meter to adjust the start and stop of the air pump 43 is a measure to prevent the hopper from overflowing or running out of material.
