Description

Technical Field

[0001] The invention relates to the technical field of soybean processing, in particular to an anaerobic soybean crushing and refining device capable of isolating from air. Background Art

[0002] In the soybean crushing process, traditional old-fashioned stone mills, manual or mechanical shaking are usually used to separate the pulp and residue. The soy products produced in this way are delicious, but the efficiency is too low. The pulp and residue automatic separation type pulping machine commonly used now improves production efficiency, but also brings some problems: in the pulp and residue separation process of the existing pulping machine, the soybean milk and fine mist are separated, and they are fully contacted with the air, so that the air is dissolved into the soybean milk to a great extent. In the process of soybean crushing, pulp and residue separation, and pulp boiling, air will escape, which will produce a lot of foam, and a large amount of defoaming agent must be used, which directly affects the taste of the subsequent processed soybean products.

[0003] At the same time, the lipoxygenase in soybeans is fully in contact with the oxygen in soy milk, catalyzing the enzymatic oxidation reaction of unsaturated fatty acids in soybeans to produce substances with a beany smell, which seriously affects the taste of soy products. Summary of the invention

[0004] The purpose of the present invention is to provide a soybean anaerobic grinding and refining system to solve the problem that the contact between soybean milk and air in the previous soybean milk production process affects the taste of soybean products.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a soybean anaerobic crushing and refining system, comprising an upper cover and a cylinder body, the upper cover and the cylinder body are buckled with each other, a hand wheel is axially rotatably connected to the upper cover, a static grinding seat is screwed on the inner wall of the hand wheel, and the static grinding seat is plugged into the upper cover, and an upper grinding plate is arranged at the lower end of the static grinding seat; a motor is installed on the lower side wall of the cylinder body, and the output end of the motor is placed in the cylinder body, a lower grinding plate is arranged on the upper side wall of the output end of the motor, and the lower grinding plate and the upper grinding plate cooperate with each other;

[0006] The cylinder body is provided with a soy milk chamber and a bean dregs chamber, and the soy milk chamber and the bean dregs chamber are separated by a partition plate; a separation basket is provided on the partition plate, and a filter is provided in the separation basket, the separation basket is fixedly installed at the output end of the motor, and the lower grinding plate and the upper grinding plate are both placed in the separation basket; a soy milk outlet is provided at the lower end of the soy milk chamber, and a bean dregs outlet is provided at the lower end of the bean dregs chamber;

[0007] A feed port is provided on the static grinding seat, and the feed port is connected to the upper grinding plate; and the feed port is connected to a feed mechanism.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] By blocking the air from dissolving during the soybean crushing and pulp-dregs separation process, the air isolation effect is achieved. This prevents a large amount of air from dissolving in the soybean milk, which results in the need to use a large amount of defoaming agent to eliminate the bubbles, seriously affecting the taste of soybean products. It also prevents the lipoxygenase from producing a strong beany smell due to sufficient oxygen. The soybean milk chamber and the soybean dregs chamber are separated by a partition plate, making it easier to separate the pulp-dregs.

[0010] During the dregs separation process, several nozzles or annular water spray systems are used to spray water at a tangential angle to dilute the dregs, thereby completing the uniform mixing of the dregs and water, increasing its fluidity so that it can flow out smoothly. At the same time, the dregs outlet is connected to an elastic material bag or a flexible outlet pipe, which is arranged below the liquid level to prevent air from entering the refiner. The pulp outlet is arranged in the form of a water return bend to prevent air from entering the refiner. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-4The present invention provides a technical solution: a soybean anaerobic crushing and refining system, comprising an upper cover 1 and a cylinder body 4, the upper cover 1 and the cylinder body 4 are buckled with each other, and a second sealing ring is provided between the upper cover 1 and the cylinder body 4 to ensure the sealing degree after buckling. A hand wheel 2 is axially rotatably connected to the upper cover 1, so that the hand wheel 2 can only rotate horizontally, and a static grinding seat 3 is screwed on the inner wall of the hand wheel 2, and the static grinding seat 3 is plugged into the upper cover 1. Through the guiding effect of the upper cover 1 on the static grinding seat 3, when the hand wheel 2 rotates, the static grinding seat 3 matched with its inner ring thread can only achieve displacement in the up and down directions. A first sealing ring is provided between the static grinding seat 3 and the opening of the upper cover 1 to ensure that the outside air is not easy to enter the cylinder body 4. An upper grinding plate 5 is provided at the lower end of the static grinding seat 3, and the upper grinding plate 5 does not rotate during the grinding process. A spring 6 is provided between the static grinding seat 3 and the lower side wall of the upper cover 1, and the spring 6 is in a compressed state to help the static grinding seat 3 reset.

[0018] A motor 7 is installed on the lower side wall of the cylinder body 4, and the output end of the motor 7 is placed in the cylinder body 4. A lower grinding plate 8 is provided on the upper side wall of the output end of the motor 7 to drive the lower grinding plate 8 to rotate. The lower grinding plate 8 cooperates with the upper grinding plate 5. Since the static grinding seat 3 can achieve up and down displacement, the height between the lower grinding plate 8 and the upper grinding plate 5 can be adjusted accordingly, thereby adjusting the coarseness of the beans ground by the grinding plate.

[0019] The cylinder body 4 is provided with a soymilk chamber and a bean dregs chamber, and the soymilk chamber and the bean dregs chamber are separated by a partition plate 9; a separation basket 10 is provided on the partition plate 9, and a filter screen is provided in the separation basket 10, and the separation basket 10 is fixedly installed at the output end of the motor 7, and the separation basket 10 and the motor cover 14 are fixed to each other. The partition plate 9 is cylindrical as a whole, and the separation basket 10 is completely covered by the upper opening of the partition plate 9. The separated soymilk flows into the soymilk chamber along the opening of the separation basket 10, and the bean dregs move obliquely upward along the separation basket 10. The lower end of the bean dregs chamber is provided with a bean dregs outlet 12. A nozzle 13 is installed in the upper cover 1, and the nozzle 13 is connected to an external water source, and the nozzle 13 is directed toward the top of the separation basket 10, or sprayed toward the cylinder wall where the bean dregs can be thrown, and the water is sprayed at the same angle as the bean dregs thrown out by the separation basket 10. It is used to give power to the dregs, so that the dregs can flow into the dregs chamber more easily after mixing with water, and then be discharged along the dregs outlet 12, which is convenient for the next grinding. The nozzle 13 can be set to make the dregs fully mixed with water or slurry, which is conducive to the flow of the diluted dregs and smooth discharge. The dregs outlet 12 is connected to the recovery mechanism to avoid direct connection with the atmosphere. An annular nozzle 16 for spraying water to the cylinder wall can also be set circumferentially at the upper cover 1 to prevent the dregs in the dregs chamber from agglomerating.

[0020] The lower grinding plate 8 and the upper grinding plate 5 are both placed in the separation basket 10; the lower end of the soy milk chamber is provided with a soy milk outlet 11 for discharging the ground soy milk. The static grinding seat 3 is provided with a feed port, and the feed port is connected to the upper grinding plate 5; the feed port is connected to a feed mechanism.

[0021] The bottom end of the cylinder 4 is provided with a waterproof cavity, and the output end of the motor 7 is placed in the waterproof cavity; a motor cover 14 is provided outside the output end of the motor 7, and the motor cover 14 is provided outside the waterproof cavity to reduce the possibility of air entering the cylinder 4 along the waterproof cavity. The horizontal height of the upper end of the soy milk outlet 11 is higher than the lower side wall of the motor cover 14, so that the soy milk in the soy milk chamber can only be discharged normally when the height is higher than the soy milk outlet 11. At this time, the soy milk will completely cover the gap between the motor cover 14 and the bottom surface of the cylinder 4, further preventing gas from flowing into the cylinder 4; a water return mechanism 15 is provided on the lower side wall of the soy milk outlet 11 to ensure that air does not enter the cylinder 4 along the soy milk outlet 11.

[0022] The feeding mechanism is a rubber bag or other elastic container, which is used to fill beans and water. There is a valve on the upper and lower parts of the rubber bag. The upper valve is for feeding beans or water, and the lower valve is sealed and connected to the inlet of the device with a quick connector. The opening and closing size of the lower valve controls the amount of soybeans or water. During the production process, the volume of the rubber bag automatically shrinks as the soybeans decrease, and the beans and water in the bag do not come into contact with the air.

[0023] Working principle: The setting of the air-isolating mechanism can eliminate the problem of contact between soy milk and air in the previous pulp-residue separation process, avoid a large amount of air dissolving in the soy milk, and then use more defoaming agent, which seriously affects the taste of soy products. At the same time, it also avoids the lipoxygenase from producing a strong bean smell due to more oxygen.

[0024] Because the solubility of air in water is different at room temperature compared to the temperature when water is boiling, the higher the temperature, the less air there is in the water. In order to further reduce the reaction of lipoxygenase, the water to be added can be preheated to boiling and then used after the water cools down. During the cooling process, the water is always in a closed state and does not come into contact with the air, which further reduces the content of air and oxygen in the water, and also reduces the content of air and oxygen in the soy milk, weakening the above reaction. At the same time, the air that produces bubbles in the soy milk is further reduced. In this way, no defoamer is required during the soybean crushing process, the beany smell is reduced, and the product tastes more fragrant.

[0025] During use, the soybeans will be compressed by the rubber bag and gradually enter the static grinding seat 3, and fall between the lower grinding plate 8 and the upper grinding plate 5. As the lower grinding plate 8 rotates, the soybeans are ground, and the ground soybean milk will be directly separated by the separation basket 10 and fall into the soybean milk chamber. The bean dregs will fly out along the separation basket 10 obliquely upward, and enter the bean dregs chamber after being impacted by the water flow sprayed from the nozzle 13. After that, the soybean milk is discharged along the return water bend mechanism 15, and the bean dregs are discharged along the bean dregs outlet 12. In this process, the bean dregs and soybean milk do not directly contact the air.

[0026] The present invention provides another technical solution, which is different from the above technical solution in that the feeding mechanism is a cage elevator, and the outlet of the cage elevator is sealed and connected to the feeding port of the static grinding seat 3, thereby isolating the outside air. The inlet of the cage elevator is connected to a container filled with soybeans and water, and the inlet is set below the water surface in the container.

[0027] Working principle: Soybeans are gradually put into the static grinding seat 3 through the lifting effect of the cage elevator, and the feeding work is completed with the injected water source. The soybeans are lifted out of the water by the cage, and the water plays a role of sealing and isolating the air. The other technical features remain unchanged.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
