Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, and specifically relates to a vacuum mixer equipment. Background Art

[0002] In the field of food processing, mixing is a crucial unit operation, and its core purpose is to ensure the uniform distribution of different components to guarantee the stable quality of the final product. In traditional technologies, the mixing of food raw materials mainly relies on traditional methods such as manual stirring or mechanical stirring. However, these methods often have low efficiency, high labor intensity, and it is difficult to achieve the ideal mixture consistency and uniformity. With the rapid development of the modern food industry, the requirements for mixing equipment are also constantly increasing. Modern mixing equipment not only needs to be able to efficiently mix various raw materials, but also must have the characteristics of simple operation, cleanliness and hygiene, and adaptability to different scales of production lines.

[0003] At present, widely used food raw material mixing equipment includes various types such as mixers, mixing tanks, and screw mixers. These equipment have played a significant role in improving the mixing efficiency. However, it cannot be ignored that they still face some challenges and limitations. When multiple different raw materials are put into the mixing equipment, affected by multiple factors such as the raw material input order, particle size, and gravity, stratification is likely to occur between the raw materials. For the stratified raw materials, the existing mixing equipment has problems such as low mixing efficiency and insufficient mixing uniformity of the upper and lower layer raw materials during the stirring process. The traditional stirring powder tank, although adding a jacket and high shear, has improved the mixing effect to a certain extent;

[0004] However, in the actual application process, the above-mentioned mixing devices still have the following problems:

[0005] 1. The traditional powder feeding method uses manual powder feeding, which has high work intensity, low efficiency, and serious dust pollution, affecting the hygiene and beauty of the workshop and increasing the cleaning difficulty. This mixing method still needs to improve in terms of efficiency;

[0006] 2. The functions of traditional mixing units are relatively single, and it cannot quickly switch between high and low shear functions inside the same machine to meet different product requirements;

[0007] 3. In traditional mixing, it can quickly drive the movement of the surrounding raw materials, but the fluidity of the raw materials near the mixing barrel wall is not satisfactory due to the influence of temperature and mixing radius. Especially when stratification occurs in the raw materials, the mixing uniformity and mixing efficiency of this part of the raw materials near the barrel wall still need to be improved, resulting in local uneven mixing.

[0008] Based on the above problems, this application document proposes a mixing equipment for raw material mixing to improve the above problems. Summary of the Utility Model

[0036] Example 1

[0037] The lifting stator controls the lifting of the stator screen by compressed air entering the cylinder at the bottom of the turbine mixing unit 3. When the customer needs to process fruits and other fragile particles, the screen can be lifted to achieve shear-free; when the customer needs granular materials or sauces, the waist-hole screen can be selected to achieve low shear; when the customer needs a better dissolution effect for powdering, the round-hole screen can be selected to achieve high shear, (as Figure 4 shown). The left half is the state of the lowered screen, and the right half is the state of the lifted screen. This function can be switched during the operation of the equipment, quickly and conveniently.

[0038] Example 2

[0039] For materials with high viscosity, the reserved design of compressed air pushing the material can introduce positive-pressure compressed air into the tank to assist the discharge pump in discharging, improve the discharge efficiency, save the time required for production batches, and thus increase the production capacity.

[0040] Working principle: First, turn on the vacuum pump 19 and the cooling water of the mixing component. The material is metered by the customer's flow meter and enters the tank quantitatively. Then, turn on the top reducer 8, and then turn on the main motor 20. The belt drive of the small pulley 23 and the large pulley 21 can drive the turbine mixing unit 3 to operate. The jacket hot water enters from the jacket hot water inlet 14 and discharges from the jacket hot water outlet 11.

[0041] Then the vacuum pump 19 starts to operate. The opening degree is automatically controlled by the air regulating valve 17 to maintain the vacuum pump 19 within the working range of 200 - 600 mbar. The powder inlet valve 15 is opened, and the powder is sucked into the tank below the liquid level by vacuum through the powder inlet valve 15. During this period, the powder inlet valve 15 is intermittently switched to maintain the vacuum degree within the working range all the time, and the powder feeding amount is controlled by the customer's weighing system.

[0042] During the powder feeding process, the reducer 8 and the main motor 20 keep running all the time. After the powder feeding is completed, the reducer 8, the main motor 20, and the vacuum pump 19 continue to run for a period of time according to the time required by the customer's process to ensure the material melting effect.

[0043] After the material melting is completed, the vacuum pump 19 is turned off, and the air regulating valve 17 is opened to automatically relieve the pressure and release the negative pressure. The reducer 8 and the main motor 20 reduce the frequency to maintain low-frequency operation to assist in discharging. At this time, the discharge valve 2 is opened, and the customer's discharge pump is turned on to start discharging to the customer's designated storage tank.
