Description
Technical Field
[0001] The present invention relates to the technical field of tofu manufacturing, and particularly relates to a device for preparing tofu by secondary hot soymilk coagulation. Background Art
[0002] Preparing tofu by secondary hot soymilk coagulation is a method of making tofu through two soymilk coagulation processes, aiming to improve the toughness, hardness and fineness of tofu so that it will not fall apart after long cooking.
[0003] When the device for preparing tofu by secondary hot soymilk coagulation processes tofu, the soaked soybeans need to be washed and then ground, and the soybean dregs in the ground paste are separated to obtain soymilk. Subsequently, magnesium emulsified coagulant is added while stirring. However, the existing devices need to perform filtration and stirring separately. This separate operation can easily cause losses and contamination of soymilk during transportation, thereby affecting the quality of the final tofu. Summary of the Invention
[0004] The purpose of the present invention is to provide a device for preparing tofu by secondary hot soymilk coagulation to solve the above problems.
[0005] To achieve the above purpose, the present invention adopts the following technical scheme: It includes a stirring cylinder, a stirring device is installed in the middle of the stirring cylinder, a filtering component used in cooperation with the stirring device is installed at the upper end of the stirring cylinder, a feed inlet is installed at the upper end of the stirring cylinder, and a discharge pipe is installed at the lower end of the stirring cylinder; The filtering component includes a rotating cylinder sleeved on the upper end of the stirring shaft in the stirring device. Two groups of mounting plates are fixedly arranged in the middle of the rotating cylinder. A spiral baffle is fixedly installed between the two groups of mounting plates. A guiding hopper is fixedly arranged at the upper end of the mounting plate. A feeding port is opened at the lower end of the guiding hopper. A guiding groove is rotatably installed at the lower periphery of the mounting plate. A discharge bin is fixedly installed at the lower end of the guiding groove. A sealing plate can be installed at the port of the discharge bin. The discharge bin penetrates through and is fixedly connected with the stirring cylinder. A plurality of air injection components are installed at the lower end of the rotating cylinder. A one-way bearing is arranged between the stirring shaft and the rotating cylinder. An additive adding pipe is installed on the side wall of the stirring cylinder; In practical applications, the device is provided with a filtering component. The soymilk with impurities is introduced into the guiding hopper through the feed inlet, and then enters the position between the two mounting plates from the feeding port. Thus, the soymilk liquid is discharged from the filter screen and then enters the bottom of the stirring cylinder. Then, the stirring device stirs the soymilk liquid at the lower end of the stirring cylinder. At the same time, due to the one-way bearing arranged between the stirring shaft and the rotating cylinder, when the output shaft of the bidirectional motor rotates forward, the stirring shaft and the rotating cylinder will rotate synchronously. When the output shaft of the bidirectional motor rotates backward, the stirring shaft will not rotate, while the stirring device can work normally. This integrated design can well avoid losses and contamination of soymilk during transportation, thereby ensuring the quality of tofu.
[0006] Further, the spiral baffle includes a spiral plate. A spiral drainage cavity is formed at the middle position of the spiral plate. A spiral diversion cavity is formed on one side close to the center inside the spiral plate. An inclined drainage hole is formed between the drainage cavity and the diversion cavity. An inclined exhaust hole is formed on one side of the diversion cavity away from the drainage hole. A plurality of groups of connecting holes are uniformly arranged inside the drainage cavity. The connecting holes are connected to the air injection assembly through pipelines; The air injection assembly includes a guide cylinder fixed to the outer wall of the rotating cylinder. A sealing plug is slidably installed inside the guide cylinder. A guide rod is fixedly arranged at the middle position of the sealing plug. A return spring is installed at the other end of the sealing plug. A fixed ring is fixedly arranged inside the guide cylinder near one end of the rotating cylinder. An air inlet hole and an air outlet hole are formed inside the guide cylinder. The air outlet hole is communicated with the inside of the drainage cavity through a pipeline. The air inlet hole is connected with an L-shaped pipeline. The air inlet end of the L-shaped pipeline is located at the lower end of the guide groove and is slidably connected with the guide rod and the guide cylinder. One-way valves are installed inside the air inlet hole and the air outlet hole. The air injection assembly and the arc-shaped plate are at the same horizontal height; In practical applications, the stirring device drives the rotating cylinder to rotate. The rotating cylinder drives the mounting plate to rotate. The mounting plate drives the spiral baffle to rotate. The soymilk liquid enters the lower end of the stirring cylinder from the filter screen. Under the action of centrifugal force, the soybean dregs will enter the guide groove along the spiral baffle. The soybean dregs entering the inside of the guide groove enter the inside of the discharge bin, thereby completing the collection of the soybean dregs; At the same time, the device is provided with an air injection assembly. When the rotating cylinder rotates, it will drive the guide cylinder to rotate. The guide rod inside the guide cylinder moves closer to the arc-shaped plate under the action of the return spring. Thus, the guide rod moves along the outer wall of the arc-shaped plate. When the guide rod moves outwards, air enters the guide cylinder. When the guide rod moves inwards, air exits the guide cylinder. The discharged gas will enter the inside of the drainage cavity, then enter the inside of the diversion cavity from the inside of the drainage cavity, and finally be discharged through the inclined exhaust hole, thereby impacting the soybean dregs, preventing the soybean dregs from adhering to the surface of the air injection assembly, and facilitating the discharge of the soybean dregs.
[0007] Further, a plurality of arc-shaped plates are fixedly arranged on the inner ring wall of the guide groove. A chamfer is arranged between two arc-shaped plates.
[0008] Further, a scraper is fixedly arranged at the lower end of the mounting plate inside the guide groove. A guide ring is fixedly arranged at the lower end of the mounting plate. The position of the mounting plate inside the guide ring is a filter screen.
[0009] Further, the stirring device includes a stirring shaft rotatably installed inside the stirring cylinder. Stirring blades are fixedly arranged on the outer wall of the lower end of the stirring shaft. A two-way motor is installed at the middle position of the upper end of the stirring cylinder. The output shaft of the two-way motor is connected to the stirring shaft.
[0010] Compared with the prior art, the present invention has the following beneficial effects: The device is provided with a filtering component. The soy milk with impurities is introduced into the guiding hopper through the feeding port, and then enters the position between the two mounting plates from the discharging port. Thus, the soy milk liquid is discharged from the filter screen and then enters the bottom of the stirring cylinder. The stirring device stirs the soy milk liquid at the lower end of the stirring cylinder. At the same time, since a one-way bearing is arranged between the stirring shaft and the rotating cylinder, when the output shaft of the bidirectional motor rotates forward, the stirring shaft and the rotating cylinder will rotate synchronously. When the output shaft of the bidirectional motor rotates reversely, the stirring shaft will not rotate, while the stirring device can work normally. This integrated design can well avoid the loss and pollution of soy milk during transportation, thus ensuring the quality of tofu.
[0011] The device is provided with an air injection component. When the rotating cylinder rotates, it will drive the guiding cylinder to rotate. The guiding rod inside the guiding cylinder approaches the arc-shaped plate under the action of the return spring, so that the guiding rod moves along the outer wall of the arc-shaped plate. When the guiding rod moves outwards, air enters the guiding cylinder, but when the guiding rod moves inwards, air is discharged from the guiding cylinder. The discharged gas will enter the drainage cavity, then enter the shunt cavity from the drainage cavity, and finally be discharged through the inclined exhaust holes, thus impacting the bean dregs, avoiding the adhesion of the bean dregs on the surface of the air injection component, and facilitating the discharge of the bean dregs.

[0015] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0016] Refer to Figure 1-8 , a device for preparing tofu with secondary hot soy milk, including a mixing drum 1, a mixing device 2 is installed at the middle position of the mixing drum 1, a filtering component 3 used in cooperation with the mixing device 2 is installed at the upper end of the mixing drum 1, a feed inlet 4 is installed at the upper end of the mixing drum 1, and a discharge pipe is installed at the lower end of the mixing drum 1; The filtering component 3 includes a rotating drum 301 sleeved on the upper end of the mixing shaft 201 in the mixing device 2. Two groups of mounting plates 308 are fixedly arranged at the middle position of the rotating drum 301. A spiral baffle 307 is fixedly installed between the two groups of mounting plates 308. A guiding hopper 302 is fixedly arranged at the upper end of the mounting plate 308. A feeding port is opened at the lower end of the guiding hopper 302. A guiding groove 304 is rotatably installed at the outer lower end of the mounting plate 308. A discharge bin 305 is fixedly installed at the lower end of the guiding groove 304. A sealing plate can be installed at the port of the discharge bin 305. The discharge bin 305 penetrates through and is fixedly connected to the mixing drum 1. Multiple groups of air injection components 306 are installed at the lower end of the rotating drum 301. A one-way bearing is arranged between the mixing shaft 201 and the rotating drum 301. An additive adding pipe is installed on the side wall of the mixing drum 1. Through holes for cooperating with the feeding port are opened on the upper-layer mounting plate; In practical applications, the device is provided with a filtering component 3. The soymilk with impurities is introduced into the inside of the guiding hopper 302 through the feeding port 4, and then enters the position between the two mounting plates 308 from the discharging port. Thus, the soymilk liquid is discharged from the filter screen and then enters the bottom of the stirring cylinder 1. The stirring device 2 stirs the soymilk liquid at the lower end of the stirring cylinder 1. At the same time, since a one-way bearing is provided between the stirring shaft 201 and the rotating cylinder 301, when the output shaft of the bidirectional motor 202 rotates forward, the stirring shaft 201 and the rotating cylinder 301 will rotate synchronously. When the output shaft of the bidirectional motor 202 rotates reversely, the stirring shaft 201 will stop rotating, while the stirring device 2 can work normally. This integrated design can well avoid the loss and pollution of soymilk during transportation, thus ensuring the quality of tofu.
[0017] Further, the spiral baffle 307 includes a spiral plate 3071. A spiral drainage cavity 3072 is formed in the middle position of the spiral plate 3071. A spiral diversion cavity 3073 is formed on the side close to the center inside the spiral plate 3071. An inclined drainage hole 3074 is formed between the drainage cavity 3072 and the diversion cavity 3073. An inclined exhaust hole 3075 is formed on the side of the diversion cavity 3073 away from the drainage hole 3074. A plurality of groups of connection holes 3076 are uniformly arranged inside the drainage cavity 3072. The connection holes 3076 are connected to the air injection component 306 through pipelines. The air injection component 306 includes a guiding cylinder 3061 fixed to the outer wall of the rotating cylinder 301. A sealing plug 3064 is slidably installed inside the guiding cylinder 3061. A guiding rod 3062 is fixedly arranged in the middle position of the sealing plug 3064. A return spring 3065 is installed at the other end of the sealing plug 3064. A fixed ring 3066 is fixedly arranged inside the guiding cylinder 3061 near one end of the rotating cylinder 301. An air inlet hole 3067 and an air outlet hole are formed inside the guiding cylinder 3061. The air outlet hole is communicated with the inside of the drainage cavity 3072 through a pipeline. The air inlet hole 3067 is connected with an L-shaped pipeline. The air inlet end of the L-shaped pipeline is located at the lower end of the guiding groove 304 and is slidably connected with the guiding rod 3062 and the guiding cylinder 3061. Check valves are installed inside the air inlet hole 3067 and the air outlet hole. The air injection component 306 and the arc-shaped plate 3041 are at the same horizontal height. In practical applications, the stirring device 2 drives the rotating cylinder 301 to rotate. The rotating cylinder 301 drives the mounting plate 308 to rotate. The mounting plate 308 drives the spiral baffle 307 to rotate. The soymilk liquid enters the lower end of the stirring cylinder 1 from the filter screen, and the soybean dregs will enter the guiding groove 304 along the spiral baffle 307 under the action of centrifugal force. The soybean dregs entering the inside of the guiding groove 304 enter the inside of the discharge bin 305, thus completing the collection of the soybean dregs. Meanwhile, the device is provided with an air pumping assembly 306. When the rotary drum 301 rotates, it drives the guide cylinder 3061 to rotate. The guide rod 3062 inside the guide cylinder 3061 approaches the arc-shaped plate 3041 under the action of the return spring 3065. Thus, the guide rod 3062 moves along the outer wall of the arc-shaped plate 3041. The guide rod 3062 extends outwards under the action of the return spring 3065. When the guide rod 3062 slides to the middle position of the arc-shaped plate, the return spring 3065 is compressed, and the gas inside the guide cylinder 3061 enters the air outlet holes. The gas enters the inside of the drainage cavity 3072, and then enters the inside of the diversion cavity 3073 from the inside of the drainage cavity 3072, and finally is discharged through the inclined exhaust holes 3075, thereby impacting the soybean dregs, preventing the soybean dregs from adhering to the surface of the air pumping assembly 306, and facilitating the discharge of the soybean dregs. When the guide rod 3062 slides to both ends of the arc-shaped plate, the return spring 3065 pushes the guide rod 3062 to extend outwards, so that the gas enters the inside of the guide cylinder 3061 from the air inlet holes 3067.
[0018] Furthermore, a plurality of arc-shaped plates 3041 are fixedly arranged on the inner ring wall of the guide groove 304, and a chamfer is arranged between two arc-shaped plates 3041. Through the arc-shaped plates 3041.
[0019] Furthermore, a scraper 309 is fixedly arranged at the lower end of the mounting plate 308 inside the guide groove 304, a guide ring 3081 is fixedly arranged at the lower end of the mounting plate 308, and the position of the mounting plate 308 inside the guide ring 3081 is a filter screen.
[0020] Furthermore, the stirring device 2 includes a stirring shaft 201 rotatably installed inside the stirring cylinder 1. Stirring blades 203 are fixedly arranged on the outer wall of the lower end of the stirring shaft 201. A two-way motor 202 is installed at the middle position of the upper end of the stirring cylinder 1, and the output shaft of the two-way motor 202 is connected to the stirring shaft 201.
[0021] Working principle: The device is provided with a filtering assembly 3. The soybean milk with impurities is introduced into the guide hopper 302 through the feed port 4, and then enters the position between the two mounting plates 308 from the feeding port. Thus, the soybean milk liquid is discharged from the filter screen, and then enters the bottom of the stirring cylinder 1. The stirring device 2 stirs the soybean milk liquid at the lower end of the stirring cylinder 1. At the same time, since a one-way bearing is arranged between the stirring shaft 201 and the rotary drum 301, when the output shaft of the two-way motor 202 rotates forward, the stirring shaft 201 and the rotary drum 301 will rotate synchronously. When the output shaft of the two-way motor 202 rotates reversely, the stirring shaft 201 does not rotate, while the stirring device 2 can work normally. This integrated design can well avoid losses and pollution of the soybean milk during transportation, thus ensuring the quality of the tofu.
