Description

Technical Field

[0001] The present invention relates to the technical field of integrated bean product preparation equipment, and in particular to an integrated preparation equipment and process for solid-phase and liquid-phase raw materials of bean products. Background Art

[0002] The integrated preparation equipment for solid and liquid raw materials of soy products is a kind of equipment that integrates the processing functions of solid and liquid raw materials. It can realize the integrated production from raw material processing to product preparation. The integrated preparation equipment for solid and liquid raw materials of soy products may include the following main parts: Raw material processing system: responsible for the pretreatment of solid raw materials such as cleaning, soaking, and crushing, as well as the purification and heating of liquid raw materials. Refining system: the pretreated solid raw materials are mixed with liquid raw materials by mechanical force and ground into fine soy milk. Cooking system: the ground soy milk is heated and boiled to kill the microorganisms and denature the protein therein, thereby enhancing the taste and nutritional value of soy products. Molding system: according to product requirements, the cooked soy milk is coagulated, pressed, cut and other molding processes are carried out to make various soy products, such as tofu, dried bean curd, etc. The integrated preparation equipment for solid and liquid raw materials of soy products can meet the production needs of soy product manufacturers for high efficiency, stability and environmental protection. When selecting and using such equipment, enterprises should fully consider factors such as its performance, production efficiency, ease of operation, and maintenance costs to ensure that the equipment can bring the greatest economic and social benefits to the enterprise.

[0003] The Chinese patent publication number is CN117016831A, which discloses a preparation device for processing soy products. Technical problem: When the bean skin is peeled off from the surface of the soy milk, the bean skin is easy to break because it is relatively thin. Technical solution: A preparation device for processing soy products, including an evaporation table, a first mounting block, an L-shaped cross bar, a first moving assembly and a power assembly, etc.; the first moving assembly is connected to the upper front side of the evaporation table; the first moving assembly is connected to the first mounting block; the power assembly is connected to the left side of the first mounting block; the power assembly is connected to two L-shaped cross bars distributed front and back. The part in contact with the bean skin is arched upward by the arc-shaped part, so when the bean skin is picked up, the air can pass through the arched part of the bean skin and enter between the bean skin and the soy milk in the cooking tank, avoiding the negative pressure generated by the bean skin and the soy milk in the cooking tank when the bean skin is picked up, which easily causes the bean skin to break.

[0015] A preparation process of a device for preparing solid-phase and liquid-phase raw materials of soy products, comprising the following steps:

[0016] Step 1: Add water to the soaking basket of the soaking chamber, heat the water to 50 to 60 degrees, then add the beans to be prepared to the soaking basket of the soaking chamber, and soak for 2 to 3 hours until the beans are fully soaked;

[0017] Step 2: Contract the hydraulic cylinder of the soaking basket, and the soaked beans leave the water surface in the soaking chamber as the soaking basket is lifted, until the driven gear row fits with the conveying pipe, stop for 2 to 3 minutes, start the servo motor, and the output end of the servo motor drives the driving gear to rotate. The driving gear drives the soaking basket baffle provided with the driven gear row to slide into the soaking basket baffle storage frame through meshing connection, so that the bean discharge hopper is connected with the conveying pipe. The lower end of the soaking basket is inclined toward the bean storage chamber, and the beans in the soaking basket roll into the conveying pipe with gravity, and then fall into the bean storage chamber;

[0018] Step 3: The bottom end of the bean storage chamber is tilted toward the bucket elevator. The beans move toward the bucket elevator due to gravity and are transported to the crushing chamber as the bucket elevator is lifted.

[0019] Step 4: Add water to the crushing chamber through the water pipe in proportion, turn on the drive motor under the crushing chamber, the output end of the drive motor drives the active electromagnet block to rotate, the active electromagnet block drives the magnet block of the crushing chamber to rotate through magnetic force, the magnet block drives the rotating shaft of the crushing chamber to rotate, the crushing paddle on the rotating shaft of the crushing chamber crushes the beans, so as to make soy milk, start the first slurry suction pump to transport the beaten soy milk to the slurry cooking chamber, after the soy milk is extracted, turn on the slag pump and the ultrasonic transducer, the remaining slag under the gravity of the slag pump passes through the slag collecting pipe and the slag discharging pipe in turn through the slag pump, and then discharged, at the same time, the ultrasonic transducer generates ultrasonic waves, and the ultrasonic waves improve the rheological properties of the slag slurry, reduce the viscosity of the slag slurry, and improve the fluidity of the slag slurry through the combined effects of the acoustic streaming effect, the acoustic cavitation effect and the alternating vibration effect. This makes it easier for the slag slurry to move downward under the action of gravity. At the same time, the vibration of ultrasonic waves also helps to accelerate the sedimentation and stratification of particles inside the slurry, further promoting the downward movement of the slurry. When discharging the slurry, the rotating shaft of the crushing chamber is driven to rotate, and the rotating shaft of the crushing chamber drives the scraper to rotate, thereby scraping off the slurry on the inner wall of the crushing chamber;

[0020] Step 5: Turn on the graphite electric heater to heat the soy milk, then start the driving motor under the cooking chamber, the output end of the driving motor drives the active electromagnet block to rotate, the active electromagnet block drives the magnet block of the cooking chamber to rotate through magnetic force, the magnet block drives the rotating shaft of the cooking chamber to rotate, the cooking stirring paddle on the rotating shaft of the cooking chamber stirs the heated soy milk to prevent it from burning;

[0021] Step 6: The cooked soybean milk is input into the forming cavity through the second slurry suction water pump. When the injection is completed, brine is added through the liquid adding pipe, and the hydraulic cylinder of the pressing frame is extended. The hydraulic cylinder of the pressing frame drives the pressing frame to move downward, and is lifted after contacting the soybean milk with the brine. It is reciprocated up and down for times until the brine and soybean milk are fully mixed to form the bean curd. The water in the waste water cavity is pumped into the pressing frame through the water pipe and the bellows by the submersible pump, and the water in the pressing frame is pressed through the water pipe and the bellows. The amount of water input into the pressing frame and the pressing time are adjusted according to the type of tofu required;

[0022] Step 7: When cleaning the equipment, inject water into the crushing chamber and the pulping chamber, turn on the two drive motors to stir the clean water, so as to flush the crushing paddle, scraper plate and pulping stirring paddle, and then turn on the ultrasonic transducer. When the ultrasonic transducer is started, it generates ultrasonic waves. When the ultrasonic waves propagate in the clean water, changes in compression force and pressure reduction will occur. When the pressure reduction reaches a certain level, tiny vacuum bubbles will be formed in the liquid. These vacuum bubbles will suddenly burst under the action of compression force, generating a strong impact force, which is enough to shake off the dirt attached to the surface of the crushing chamber and the pulping chamber, thereby achieving the cleaning effect. When the ultrasonic frequency is high, the liquid particles will produce high-speed movement under the action of ultrasonic waves. The high-speed movement causes the liquid particles to collide with the dirt, which can grow into patches of bean dregs and soy milk residues and adhere to the surfaces of the crushing chamber and the pulping chamber, so that the patches of bean dregs and soy milk residues are peeled off and dispersed and emulsified in clean water. When ultrasonic waves propagate in clean water, they will flow along the direction of the sound waves. This flow stirs the fine dirt on the surface of the target object, prompting convection of the clean water on the surface of the dirt, thereby accelerating the dissolution and transportation of the dirt. This effect makes the overall cleaning of the surface of the crushing chamber and the pulping chamber more effective.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The lower ends of the crushing chamber and the pulping chamber of the present invention are provided with a magnetic follower mechanism, a first driving mechanism is provided below the crushing chamber, and a second driving mechanism is provided below the pulping chamber. When in use, the driving motor below the crushing chamber is turned on, and the output end of the driving motor drives the active electromagnet block to rotate, and the active electromagnet block drives the magnet block of the crushing chamber to rotate through magnetic force, and the magnet block drives the rotating shaft of the crushing chamber to rotate, and the crushing paddle on the rotating shaft of the crushing chamber crushes the beans, thereby making soy milk, and the driving motor below the pulping chamber is started, and the output end of the driving motor drives the active electromagnet block to rotate, and the active electromagnet block drives the magnet block of the pulping chamber to rotate through magnetic force, and the magnet block drives the rotating shaft of the pulping chamber to rotate, and the pulping stirring paddle on the rotating shaft of the pulping chamber stirs the heated soy milk, thereby preventing it from burning, and the driving of the rotating shaft of the crushing chamber and the rotating shaft of the pulping chamber is realized by magnetic force, thereby improving the sealing performance of the crushing chamber and the pulping chamber, and solving the problem.

[0025] 2. When the soaked beans in the present invention are conveyed, the hydraulic cylinder of the soaking basket is retracted, and the soaked beans leave the water surface in the soaking chamber as the soaking basket is lifted, until the driven gear row fits with the conveying pipe, and the process stops for 2 to 3 minutes, and the servo motor is started. The output end of the servo motor drives the driving gear to rotate, and the driving gear drives the soaking basket baffle provided with the driven gear row to slide into the soaking basket baffle storage frame through meshing connection, so that the bean outlet hopper is connected with the conveying pipe, and the lower end of the soaking basket is inclined toward the bean storage chamber. The beans in the soaking basket roll into the conveying pipe with gravity, and fall into the bean storage chamber, so that the conveying of the beans is more automated.

[0026] 3. When the present invention is used, when discharging slurry, the slurry pump and ultrasonic transducer are turned on, and the remaining slurry under the gravity of the slurry pump passes through the slurry collecting pipe and the slurry discharging pipe in sequence through the slurry pump, so as to be discharged. At the same time, the ultrasonic transducer generates ultrasonic waves, which improve the rheological properties of the slurry, reduce the viscosity of the slurry, and improve the fluidity of the slurry through the combined effects of the acoustic flow effect, the acoustic cavitation effect, and the alternating vibration effect. This makes it easier for the slurry to move downward under the action of gravity. At the same time, the vibration of ultrasound can also help accelerate the sedimentation and stratification of particles inside the slurry, further promoting the downward movement of the slurry. When discharging the slurry, the crushing chamber rotating shaft is driven to rotate at the same time, and the crushing chamber rotating shaft drives the scraper plate to rotate, thereby scraping off the slurry on the inner wall of the crushing chamber. When cleaning the equipment, water is injected into the crushing chamber and the pulp boiling chamber, and the two drive motors are turned on to stir the clean water, thereby flushing the crushing paddle, scraper plate and pulp boiling stirring paddle, and then the ultrasonic transducer is turned on. When the ultrasonic transducer is started, ultrasonic waves are generated. When ultrasonic waves propagate in clean water, changes in compression force and pressure reduction will occur. When the pressure reduction reaches a certain level, tiny vacuum bubbles will be formed in the liquid. These vacuum bubbles will suddenly burst under the action of compression force, generating a strong impact force, which is enough to shake off the dirt attached to the surface of the crushing chamber and the pulping chamber, thereby achieving the cleaning effect. When the ultrasonic frequency is high, the liquid particles will produce high-speed movement under the action of ultrasonic waves. The high-speed movement causes the liquid particles to collide with the dirt, which can grow into patches of bean dregs and soy milk residues and adhere to the surfaces of the crushing chamber and the pulping chamber, so that the patches of bean dregs and soy milk residues are peeled off and dispersed and emulsified in clean water. When ultrasonic waves propagate in clean water, they will flow along the direction of the sound waves. This flow stirs the fine dirt on the surface of the target object, prompting convection of the clean water on the surface of the dirt, thereby accelerating the dissolution and transportation of the dirt. This effect makes the overall cleaning of the surface of the crushing chamber and the pulping chamber more effective. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A preparation process of a device for preparing solid-phase and liquid-phase raw materials of soy products, comprising the following steps:

[0043] Step 1: Add water into the soaking basket 10 of the soaking chamber 4, heat the water to 50 to 60 degrees, then add the beans to be prepared into the soaking basket 10 of the soaking chamber 4, and soak for 2 to 3 hours until the beans are fully soaked;

[0044] Step 2: Contract the soaking basket hydraulic cylinder 14, and the soaked beans leave the water surface in the soaking chamber 4 as the soaking basket 10 is lifted, until the driven gear row 39 fits with the conveying pipe 15, stop for 2 to 3 minutes, start the servo motor, and the output end of the servo motor drives the driving gear 40 to rotate. The driving gear 40 drives the soaking basket baffle 37 provided with the driven gear row 39 to slide into the soaking basket baffle storage frame 11 through meshing connection, so that the bean discharge hopper 38 is not connected with the conveying pipe 15. The lower end of the soaking basket 10 is inclined toward the bean storage chamber 5, and the beans in the soaking basket 10 roll into the conveying pipe 15 with gravity, and then fall into the bean storage chamber 5;

[0045] Step 3: The bottom end of the bean storage chamber 5 is tilted toward the bucket elevator 16, and the beans move toward the bucket elevator 16 due to gravity, and are transported to the crushing chamber 6 as the bucket elevator 16 is lifted;

[0046] Step 4: Add water to the crushing chamber 6 through the water adding pipe in proportion, turn on the driving motor 41 below the crushing chamber 6, the output end of the driving motor 41 drives the active electromagnet block 18 to rotate, the active electromagnet block 18 drives the magnet block 46 of the crushing chamber 6 to rotate through magnetic force, the magnet block 46 drives the crushing chamber rotating shaft 20 to rotate, the crushing paddle 21 on the crushing chamber rotating shaft 20 crushes the beans, so as to make soy milk, start the first slurry suction water pump 23 to transport the beaten soy milk to the slurry cooking chamber 7, after the soy milk is extracted, turn on the slag pump 42 and the ultrasonic transducer 45, the remaining slag under the gravity of the slag pump 42 passes through the slag collecting pipe 44 and the slag discharging pipe 43 in turn through the slag pump 42, so as to be discharged, and at the same time the ultrasonic transducer 45 generates ultrasonic waves, and the ultrasonic waves improve the rheological properties of the slag slurry, reduce the viscosity of the slag slurry, and improve the fluidity of the slag slurry through the combined effects of the acoustic flow effect, the acoustic cavitation effect and the alternating vibration effect. This makes it easier for the slag slurry to move downward under the action of gravity. At the same time, the vibration of the ultrasonic wave also helps to accelerate the sedimentation and stratification of particles inside the slurry, further promoting the downward movement of the slurry. When discharging the slurry, the crushing chamber rotating shaft 20 is driven to rotate at the same time, and the crushing chamber rotating shaft 20 drives the scraper plate 22 to rotate, thereby scraping off the slurry on the inner wall of the crushing chamber 6;

[0047] Step 5: Turn on the graphite electric heater 51 to heat the soymilk, then start the drive motor 41 under the cooking chamber 7, the output end of the drive motor 41 drives the active electromagnet block 18 to rotate, the active electromagnet block 18 drives the magnet block 46 of the cooking chamber 7 to rotate through magnetic force, the magnet block 46 drives the cooking chamber rotating shaft 24 to rotate, the cooking stirring paddle 25 on the cooking chamber rotating shaft 24 stirs the heated soymilk to prevent it from burning;

[0048] Step 6: The cooked soybean milk is input into the forming cavity 8 through the second slurry suction pump 27. When the injection is completed, brine is added through the liquid adding pipe, and the pressing frame hydraulic cylinder 28 is extended. The pressing frame hydraulic cylinder 28 drives the pressing frame 29 to move downward, and then it is lifted after contacting the soybean milk with brine, and it is reciprocated up and down 8 to 10 times until the brine and soybean milk are fully mixed to form the bean curd. The water in the waste water cavity 9 is extracted by the submersible pump 32 and input into the pressing frame 29 through the water pipe 33 and the bellows 35, and the flocculent bean curd is pressed. The amount of water input into the pressing frame 29 and the pressing time are adjusted according to the type of tofu required;

[0049] Step seven: When cleaning the equipment, water is injected into the crushing chamber 6 and the pulping chamber 7, and the two driving motors 41 are turned on to stir the clean water, thereby flushing the crushing paddle 21, the scraping plate 22 and the pulping stirring paddle 25, and then the ultrasonic transducer 45 is turned on. When the ultrasonic transducer 45 is started, ultrasonic waves are generated. When the ultrasonic waves propagate in the clean water, changes in compression force and pressure reduction will occur. When the pressure reduction reaches a certain level, tiny vacuum bubbles will be formed in the liquid. These vacuum bubbles will suddenly burst under the action of the compression force, generating a strong impact force, which is sufficient to shake off the dirt attached to the surface of the crushing chamber 6 and the pulping chamber 7, thereby achieving the cleaning effect. When the ultrasonic frequency is high, the liquid particles will produce high-speed movement under the action of the ultrasonic wave. The high-speed movement causes the liquid particles to collide with the dirt, and the patches of bean dregs and soy milk residues that can grow and adhere to the surfaces of the crushing chamber 6 and the pulping chamber 7 are peeled off and dispersed and emulsified in the clean water. When the ultrasonic wave propagates in the clean water, it will generate flow along the direction of the sound wave. This flow stirs the fine dirt on the surface of the target object, prompting the clean water on the surface of the dirt to produce convection, thereby accelerating the dissolution and transportation of the dirt. This effect makes the overall cleaning of the surface of the crushing chamber 6 and the pulping chamber 7 more effective.
