TECHNICAL FIELD
[0001] The present application relates to the technical field of soybean pulping, and particularly relates to a nitrogen-filled pulping equipment and a pulping process. BACKGROUND
[0002] Soy milk is a milky liquid product with good extraction properties and a milky white to light yellow color after grinding of soybeans. First, soy milk is prepared by pulping of soybeans, and then post-processing such as sterilization is performed to obtain soy milk.
[0003] In the pulping process of soybeans, the soybeans are usually broken or ground. Since the soybeans contain unsaturated fatty acids and fatty oxidation enzymes, the fatty oxidation enzymes can catalyze the fatty oxidation reaction, and then produce substances with a soybean odor.
[0004] In order to reduce the soybean odor, most factories use a nitrogen environment for pulping to avoid the generation of oxidation reaction. Since manual grinding is difficult to produce in a nitrogen environment, an automatic pulping equipment is used for pulping. However, the automatic pulping equipment cannot adjust the feeding speed, and cannot perceive the grinding process of the grinding disc as compared with manual grinding. If the feeding speed is too fast, the soybeans are not completely ground before being discharged, resulting in waste. If the feeding speed is too slow, the pulping efficiency is reduced. SUMMARY
[0005] The present application discloses a nitrogen-filled pulping equipment and a pulping process, which aims to solve the technical problem that the automatic pulping equipment cannot adjust the feeding speed, and the feeding speed is too fast or too slow to affect the pulping quality.
[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:
[0007] A nitrogen-filled pulping equipment, comprising a cleaning mechanism, one end of the cleaning mechanism is connected with a material distribution mechanism, the material distribution mechanism comprises an outer cover, a recess is arranged on one side of the outer wall of the outer cover, and a rotating disc is arranged in the recess, a plurality of grooves are arranged on the rotating disc, a through hole is arranged on one side of the outer wall of the outer cover, the center axis of the through hole coincides with the center axis of the outer cover, the through hole is located at the upper position of the outer cover, the diameter of the through hole is equal to the diameter of the groove, a plurality of second liquid leakage holes are arranged on one side of the inner wall of the outer cover, a motor is connected with one side of the outer wall of the outer cover, one end of the motor is connected with a connecting shaft, the connecting shaft penetrates through the rotating disc and is connected with a connector, the connector is fixed on one side of the outer wall of the rotating disc, one side of the through hole is connected with a pulping mechanism, the pulping mechanism comprises a connecting pipe, one end of the connecting pipe is connected with the through hole, a hopper is connected with the bottom end of the connecting pipe, a corrugated hose is connected with the bottom end of the hopper, an electric grinding disc is connected with the bottom end of the corrugated hose, a drainage groove is connected with one side of the electric grinding disc, and a pressure plate is arranged on the inner wall of the bottom end of the drainage groove.
[0008] Equipped with a feeding mechanism, soybeans are collected at the lower end of the washing mechanism after entering. When an empty trough in the turntable rotates to its lower position, the soybeans enter the trough and rotate with it until they reach the top. From there, the soybeans enter the pulping mechanism through a through-hole. Any residual liquid in the soybeans is discharged through a second drain hole, and the flow rate is further slowed by a funnel, ensuring that the soybeans enter the electric grinding disc evenly. This guarantees the grinding precision of the soybeans and reduces waste during grinding. Simultaneously, when the slurry enters the diversion trough, a pressure plate detects whether liquid is flowing through it. If no liquid flows through for an extended period, the equipment automatically controls the motor to adjust the turntable speed, thus automatically adjusting the feeding speed according to the grinding rate. This maximizes the grinding efficiency of the electric turntable while ensuring grinding quality.
[0009] In a preferred embodiment, the electric turntable includes a feed hole, and a ball bearing seal is provided on the inner wall of the top of the feed hole. The ball bearing seal is also connected to the bottom end of the corrugated hose. A motor housing is provided at the bottom of the electric turntable for driving the electric turntable. One end of the drainage channel is connected to a drainage pipe. The cleaning mechanism includes a feed tank with an inclined inner wall. A feed inlet is provided at the top of the feed tank and connected to a conveying device. Multiple leakage holes are provided on the inner wall of the bottom of the feed tank. Multiple protrusions are provided on the inner wall of the top of the feed tank. Multiple high-pressure nozzles are provided on one inner wall of the feed tank, and the multiple high-pressure nozzles are placed at an angle. One end of the head is connected to a liquid-passing pipe, the bottom end of which is connected to a water tank. The top of the water tank has a liquid inlet. The bottom end of the electric grinding disc is connected to a sealing box. The top of the sealing box is also connected to the outer wall of the connecting pipe, and a sealing ring is provided at the connection. The other side of the sealing box is connected to a drainage channel, and a sealing ring is also provided at the connection. A nitrogen filling machine is provided on one outer wall of the sealing box. The nitrogen filling machine includes an air inlet pipe, which is connected to the inner wall of the sealing box. A waste liquid tank is connected to one outer wall of the sealing box. A waste outlet is provided on one side of the waste liquid tank. A bracket is connected to the bottom end of the waste liquid tank. A second bracket is connected to the bottom end of the water tank. A third bracket is connected to one side of the feed hopper.
[0010] By incorporating a nitrogen filler and a sealed box, part of the pulping mechanism is contained within the sealed box, which creates a relatively sealed environment. This ensures that the pulping process is conducted in a nitrogen environment, preventing the formation of a beany smell. Furthermore, the sealed box further reduces the nitrogen filling range, thereby lowering nitrogen consumption, saving costs, and improving the maintenance efficiency of the nitrogen filler.
[0011] A pulping process includes the following specific steps:
[0012] S1: Soaking soybeans: Soaking soybean raw materials for later use;
[0013] S2: Entering the grinding equipment: The soaked soybeans, along with water, enter the grinding equipment;
[0014] S3: Cleaning and Filtration: The soybeans are cleaned and filtered through the equipment's cleaning mechanism;
[0015] S4: Batch processing: The processed soybeans are processed in batches using the equipment's feeding mechanism;
[0016] S5: Nitrogen filling: Using a nitrogen filling machine to fill the sealed chamber with nitrogen to create a nitrogen environment;
[0017] S6: Pulping: The soybeans, after being processed in batches, are fed into an electric grinding disc and pulped in a nitrogen environment;
[0018] S7: Collect slurry: Collect slurry through the drainage pipe, and seal immediately after collecting a certain amount of slurry;
[0019] S8: Filtration: Filter the collected slurry to remove the residue and obtain the finished slurry;
[0020] In step S3, the operation method for cleaning the filter water is to rinse it under high pressure, remove the residual water on the surface of the soybeans, and then drain the water.
[0021] First, the soybeans are soaked. Then, the soaking water and soybeans are fed into the feeding tank for further processing, reducing manual cleaning steps and improving work efficiency. At the same time, when the soybeans enter the feeding tank, the surface of the soybeans is washed by high-pressure nozzles, causing the soybeans to move along the inner wall of the feeding tank. When they come into contact with the raised strips on the upper part of the inner wall of the feeding tank, the skin of the soybeans is cleaned a second time. Wastewater is discharged through the drain hole, thus ensuring the cleaning quality of the soybean surface and ensuring the taste of the pulp.
[0022] As described above, a nitrogen-filled grinding equipment includes a cleaning mechanism. One end of the cleaning mechanism is connected to a distributing mechanism. The distributing mechanism includes an outer cover. A groove is provided on one side of the outer wall of the outer cover, and a turntable is disposed in the groove. The turntable has multiple empty slots. A through hole is provided on one side of the outer wall of the outer cover. The central axis of the through hole coincides with the central axis of the outer cover, and the through hole is located at the upper part of the outer cover. The diameter of the through hole is equal to the diameter of the empty slots. Multiple second leakage holes are provided on one side of the inner wall of the outer cover. A motor is connected to the outer wall of the rotary table. One end of the motor is connected to a connecting shaft, which passes through the rotary table and connects to a connector. The connector is fixed to one side of the outer wall of the rotary table. A pulping mechanism is connected to one side of the outer wall of the through hole. The pulping mechanism includes a connecting pipe, one end of which is connected to the through hole. A funnel is connected to the bottom end of the connecting pipe, and a corrugated hose is connected to the bottom end of the funnel. An electric grinding disc is connected to the bottom end of the electric grinding disc, and a flow channel is connected to one side of the electric grinding disc. A pressure plate is provided on the inner wall of the bottom end of the flow channel. The nitrogen-filled grinding equipment and pulping process provided by this invention have the technical effect of automatically adjusting the feeding speed according to the grinding speed, maximizing the grinding efficiency of the electric rotary table while ensuring grinding quality.
