Description

Technical Field

[0001] This utility model belongs to the field of soybean product processing technology, specifically relating to a coagulation device for producing tofu. Background Technology

[0002] The production of tofu requires a coagulation process. The specific steps are as follows: the prepared coagulant (such as brine or gypsum solution) is placed in a ladle, and then the coagulant is slowly dripped into the cooked soy milk. During the dripping process, the soy milk needs to be stirred continuously to ensure that the coagulant is evenly distributed. The degree of tofu coagulation is controlled by controlling the dripping speed of the coagulant and the strength and frequency of stirring.

[0003] However, manually dripping coagulant and stirring soy milk is not only laborious and tedious, but also makes it difficult to control the frequency of stirring and dripping coagulant. This means that the quality of the soy milk curdling is affected by the operator's experience, making it difficult for operators with different experience levels to produce high-quality tofu. Therefore, a curdling device for tofu production is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a curdling device for producing tofu, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coagulation device for producing tofu, comprising a support assembly, a stirring assembly, a transmission assembly, a storage assembly, a coagulation assembly, and a storage tank. The support assembly includes a base, and an electric push rod is connected to the upper surface of the base. The top end of the electric push rod is connected to the same placement plate.

[0006] The stirring assembly includes a stirring rod, which is rotatably connected inside the placement plate. The top end of the stirring rod is connected to the output shaft below the motor, and the motor is connected to the placement plate.

[0007] The transmission assembly includes a first pulley group, the output shaft above the motor is connected to the first pulley group, and the first pulley group is connected to a second pulley group via a belt.

[0008] The storage assembly includes a storage shell connected to the upper surface of the placement plate, and two discharge pipes connected to the bottom of the storage shell;

[0009] The slurry application assembly includes a conveying cylinder, which is snapped into a placement plate. A spiral conveying rod is rotatably connected inside the conveying cylinder. The top end of the spiral conveying rod is connected to a second pulley assembly. The bottom ends of two discharge pipes are connected to the conveying cylinder. A fixed shell is connected to the bottom end of the conveying cylinder. Several slurry application holes are opened at the bottom of the fixed shell.

[0010] The storage tank includes a tank body, which is attached to the upper surface of the base, and the stirring rod is disposed inside the tank body.

[0011] By setting up the above structure and controlling the motor, the rotating stirring rod can stir the soy milk in the bucket, while the rotating spiral conveyor rod can transport the coagulant in the conveying cylinder to the fixed shell and drip it into the soy milk in the bucket through several drop holes, so that the soy milk can be evenly mixed with the coagulant. The speed of the stirring rod and the spiral conveyor rod can be controlled by controlling the speed of the motor. When the speed of stirring the soy milk increases, the spiral conveyor rod with a faster speed can also simultaneously drip the coagulant in the conveying cylinder into the soy milk in the bucket quickly. This not only makes the operation simple but also improves the applicability of the device.

[0012] As a preferred embodiment, a positioning frame is connected to the upper surface of the base, and a positioning block is connected to one side of the barrel.

[0013] By setting up a positioning block and a positioning frame, the positioning block is slidably connected inside the positioning frame, and the positioning frame can limit the bucket body through the positioning block, so that the soy milk inside the bucket will not slip during the stirring process.

[0014] As a preferred embodiment, the positioning block is inserted into the positioning frame.

[0015] As a preferred embodiment, the upper surface of the base is connected to two telescopic rods, the top ends of which are connected to the lower surface of the same placement plate.

[0016] As a preferred embodiment, the electric push rod is positioned between the two telescopic rods, and the electric push rod and the two telescopic rods are located on the same side of the barrel.

[0017] By setting telescopic rods, the two telescopic rods can limit the movement of the placement plate, so that the placement plate will not shake during movement, and the placement plate can drive the stirring rod to move smoothly along the axial direction of the telescopic rods.

[0018] As a preferred embodiment, the storage shell is connected to the conveying cylinder through two discharge pipes, and the conveying cylinder is connected to several slurry holes through a fixed shell.

[0019] By setting up discharge pipes, the coagulant in the storage tank can move into the conveying cylinder through two inclined discharge pipes.

[0020] As a preferred embodiment, the fixing shell is located on one side of the stirring rod and inside the barrel.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention comprises a transmission assembly, a storage assembly, a dispensing assembly, and a stirring assembly. A motor is controlled to operate, and a rotating stirring rod stirs the soy milk in the container. Simultaneously, a rotating spiral conveyor conveys the coagulant from the conveying cylinder to the fixed shell, where it drips through several dispensing holes into the soy milk in the container. This ensures the soy milk is evenly mixed with the coagulant. The speed of the stirring rod and the spiral conveyor can be controlled by adjusting the motor speed. When the soy milk stirring speed increases, the faster-rotating spiral conveyor also simultaneously drips the coagulant from the conveying cylinder into the soy milk in the container. This design not only simplifies operation but also improves the applicability of the device.

[0023] This invention features a positioning block and a positioning frame. The positioning block is slidably connected inside the positioning frame, and the positioning frame can limit the position of the bucket by the positioning block, preventing the soy milk inside the bucket from slipping during the stirring process.
