[0002] Currently, the mechanical equipment for producing yuba (bean curd sheets) all uses steam heating to form a film. Hot steam is introduced into a steam coil. The hot steam emits heat through the steam coil and acts on the soy milk tank above the steam coil to heat the soy milk, causing it to reach a preset temperature. A cooling mechanism is then used to cool the soy milk in the tank, causing the soy milk to condense into yuba (bean curd skin).

At this time, the soy milk liquid injected with the coagulant needs to be stirred. This paper proposes a molding device for producing children's bean curd sheets and a molding process thereof, which can adjust the stirring rate according to the injection amount of the additive.

If the flow rate information is not within the flow rate threshold, the judgment module forms the judgment information for controlling the linear moving part A.

[0032] A forming process for producing children's bean curd sticks, using the above-mentioned forming device for producing children's bean curd sticks, comprises the following steps:

[0033] Step 1: Soaking the beans that have been screened for impurities and then performing a grinding process, and then filtering the soy milk after the grinding process;

[0034] Step 2: The technician pours soy milk into the liquid tank and activates the heating mechanism to heat the soy milk until the temperature of the soy milk is within the temperature threshold;

[0035] Step 3: Then, the linear motion member A is started to push the piston plate to perform linear motion in the vertical direction within the housing, thereby pushing the coagulant in the housing into the liquid tank through the injection tube. At the same time, the piston plate pushes the push column to slide along the spiral groove provided on the rod body, thereby pushing the two rod bodies to perform horizontal rotational motion. The rod body pushes the disk body to perform horizontal rotational motion. The disk body drives the arc-shaped pulley disc to rotate synchronously via the linear motion member B installed thereon. The three annularly distributed arc-shaped pulley discs further drive the rotating shaft and the sleeve to perform horizontal rotational motion in opposite directions via the elastic belt. At this time, the rotating shaft and the sleeve push the two corresponding stirring blades to perform horizontal rotational motion in opposite directions to stir the soy milk injected with the coagulant in the liquid tank.

[0036] Step 4: According to the injection amount of the coagulant, the linear motion member B is adjusted to push the arc-shaped pulley to perform linear motion in the horizontal direction, and the radius of the driving end of the elastic belt is changed to adjust the rotation speed of the stirring blade;

[0037] Step 5: After the coagulant is injected, the cooling mechanism is started to cool the soy milk to form bean curd sheets, and one end of the formed bean curd sheets is overlapped on the transfer mechanism to peel and transfer the formed bean curd sheets;

[0038] Step 6: drying the peeled and transported yuba and then softening it;

[0039] Step 7, cutting the softened bean curd sheets and drying them again, sterilizing and packaging the dried bean curd sheets;

[0040] Step 8: Obtaining the coagulant flow rate information, soy milk temperature rise information, soy milk temperature drop information, and stirring blade speed information through the information acquisition module;

[0041] Step 9: Compare the obtained coagulant flow rate information, soy milk temperature rise information, soy milk temperature drop information and stirring blade speed information with the corresponding flow rate threshold, temperature rise threshold, temperature drop threshold and speed threshold. If the flow rate information is not within the flow rate threshold, the judgment module forms the judgment information for controlling the linear moving part A. At this time, the control module receives the judgment information for controlling the linear moving part A and controls the linear moving part A until the flow rate information is within the flow rate threshold. If the temperature rise information is not within the temperature rise threshold, the judgment module forms the judgment information for regulating the heating mechanism. The control module receives the judgment information for regulating the heating mechanism. The heating mechanism is controlled by the judgment information of the control until the temperature rise information is within the temperature rise threshold. If the temperature drop information is not within the temperature drop threshold, the judgment module forms the judgment information for regulating the cooling mechanism. The control module receives the judgment information for regulating the cooling mechanism and regulates the cooling mechanism until the temperature drop information is within the temperature drop threshold. If the speed information is not within the speed threshold, the judgment module forms the judgment information for regulating the linear moving part B. The control module receives the judgment information for regulating the linear moving part B and regulates the linear moving part B until the speed information is within the speed threshold.

[0042] Step 10: Under the condition that the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the stirring blade speed information are all within corresponding thresholds, the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the stirring blade speed information are dimensionlessly processed and then imported into the bean curd sheet forming model to output a forming coefficient. The judgment module receives the forming coefficient and compares it with the coefficient threshold. If the forming coefficient is not within the coefficient threshold, the judgment module generates an adjustment signal for adjusting the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the stirring blade speed information. The control module receives the adjustment signal and adjusts at least one of the linear moving part A, the linear moving part B, the heating mechanism, and the cooling mechanism until the forming coefficient is within the coefficient threshold.

[0043] The present invention provides a forming device and a forming process for producing children's bean curd sticks, which have the following beneficial effects compared with the prior art:

[0044] 1. The relevant personnel inject soy milk into the liquid tank. At this time, the heating mechanism is started to heat the soy milk until the temperature of the soy milk is within the temperature threshold. Then, the linear motion part A is started to push the piston plate to perform linear motion in the vertical direction in the box body, thereby pushing the coagulant in the box body into the liquid tank through the injection pipe. At the same time, the piston plate pushes the pushing column to slide along the spiral groove provided on the rod body, thereby pushing the two rod bodies to rotate in the horizontal direction. The rod body pushes the disk body to rotate in the horizontal direction. The disk body drives the arc-shaped pulley disc to rotate synchronously through the linear motion part B installed thereon. The three annular arc-shaped pulley discs further drive the rotating shaft and the sleeve to rotate in opposite directions in the horizontal direction through the elastic belt. At this time, the rotating shaft and the sleeve push the corresponding two stirring blades to rotate in opposite directions in the horizontal direction to stir the soy milk injected with the coagulant in the liquid tank. At the same time, the linear motion part B can be adjusted according to the amount of coagulant injected to push the arc-shaped pulley disc to perform linear motion in the horizontal direction, and the radius of the driving end of the elastic belt can be changed to adjust the speed of the stirring blade.

[0086] A forming process for producing children's bean curd sticks, using the above-mentioned forming device for producing children's bean curd sticks, comprises the following steps:

[0087] Step 1: Soaking the beans that have been screened for impurities and then performing a grinding process, and then filtering the soy milk after the grinding process;

[0088] Step 2: The technician pours soy milk into the liquid tank 2 and activates the heating mechanism 3 to heat the soy milk until the temperature of the soy milk is within the temperature threshold;

[0089] Step 3: Then, the linear motion member A 603 is activated to push the piston plate 604 to perform a vertical linear motion in the housing 601, thereby pushing the coagulant in the housing 601 into the liquid tank 2 through the injection tube 606. At the same time, the piston plate 604 pushes the push column to slide along the spiral groove provided on the rod body 6051, thereby pushing the two rod bodies 6051 to perform a horizontal rotational motion. The rod body 6051 pushes the disk body 6054 to perform a horizontal rotational motion. The disk body 6054 drives the arc-shaped pulley disc 6055 to rotate synchronously via the linear motion member B installed thereon. The three annular arc-shaped pulley discs 6055 further drive the rotating shaft 6052 and the sleeve 6053 to perform horizontal rotational motion in opposite directions via the elastic belt 6058. At this time, the rotating shaft 6052 and the sleeve 6053 push the two corresponding stirring blades 6057 to perform horizontal rotational motion in opposite directions, thereby stirring the soy milk injected with the coagulant in the liquid tank 2.

[0090] Step 4: According to the amount of coagulant injected, the linear motion member B is adjusted to push the arc pulley 6055 to perform linear motion in the horizontal direction, and the radius of the driving end of the elastic belt 6058 is changed to adjust the rotation speed of the stirring blade 6057;

[0091] Step 5: After the coagulant is injected, the cooling mechanism is started to cool the soy milk to form bean curd sheets, and one end of the formed bean curd sheets is overlapped on the transfer mechanism to peel and transfer the formed bean curd sheets;

[0092] Step 6: drying the peeled and transported yuba and then softening it;

[0093] Step 7, cutting the softened bean curd sheets and drying them again, sterilizing and packaging the dried bean curd sheets;

[0094] Step 8: The information acquisition module 701 is used to obtain the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the rotation speed information of the stirring blade 6057;

[0095] Step 9: Compare the obtained coagulant flow rate information, soy milk temperature rise information, soy milk temperature drop information and the rotation speed information of the stirring blade 6057 with the corresponding flow rate threshold, temperature rise threshold, temperature drop threshold and rotation speed threshold. If the flow rate information is not within the flow rate threshold, the judgment module 703 forms the judgment information for controlling the linear moving part A603. At this time, the control module 704 receives the judgment information for controlling the linear moving part A603 and controls the linear moving part A603 until the flow rate information is within the flow rate threshold. If the temperature rise information is not within the temperature rise threshold, the judgment module 703 forms the judgment information for regulating the heating mechanism 3. The control module 704 receives the judgment information for controlling the linear moving part A603 and controls the linear moving part A603 until the flow rate information is within the flow rate threshold. The heating mechanism 3 is controlled by the judgment information of regulating the heating mechanism 3 until the temperature rise information is within the temperature rise threshold. If the temperature drop information is not within the temperature drop threshold, the judgment module 703 generates judgment information for regulating the cooling mechanism 4. The control module 704 receives the judgment information for regulating the cooling mechanism 4 and regulates the cooling mechanism 4 until the temperature drop information is within the temperature drop threshold. If the speed information is not within the speed threshold, the judgment module 703 generates judgment information for regulating the linear moving part B. The control module 704 receives the judgment information for regulating the linear moving part B and regulates the linear moving part B until the speed information is within the speed threshold.

[0096] Step 10: Under the condition that the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the speed information of the stirring blade 6057 are all within the corresponding thresholds, the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the speed information of the stirring blade 6057 are dimensionlessly processed and then imported into the bean curd sheet forming model to output a forming coefficient. The judgment module 703 receives the forming coefficient and compares it with the coefficient threshold. If the forming coefficient is not within the coefficient threshold, the judgment module 703 generates an adjustment signal for adjusting the coagulant flow rate information, the soy milk temperature rise information, the soy milk temperature drop information, and the speed information of the stirring blade 6057. The control module 704 receives the adjustment signal and adjusts at least one of the linear moving part A, the linear moving part B, the heating mechanism 3, and the cooling mechanism 4 until the forming coefficient is within the coefficient threshold.
