Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a bean curd skin forming system for preparing bean curd sticks. Background Art

[0002] The main process flow of the yuba machine is: heat the stainless steel conveyor belt with a steam water tank → apply soybean milk on the surface of the stainless steel conveyor belt → evaporate the moisture of the soybean milk to form yuba film → peel the film off the stainless steel conveyor belt → use soybean milk steam and hot air to soften the yuba film → cut the yuba film into continuous long sheets → shape it into round bamboo strips → pre-dry → cut horizontally → sort.

[0003] The existing authorization announcement number is CN220024120U, which is a steel belt crusting device for producing yuba, comprising a frame, two rollers are rotatably connected at both ends of the frame, and a common steel belt is sleeved on the outer side of the two rollers, and the circumference of the steel belt is greater than

[0004] The circumference of the circumscribed ellipse of the two rollers is set, and the upper part of the frame is located between the two rollers and is provided with a steam pot with a bottom lower than the inner side of the upper end of the steel belt but an upper end higher than the upper end of the steel belt. The two sides of the steel belt are set close to the side walls of the steam pot, and two symmetrical silicone retaining edges are set on the edges of the two sides of the steel belt. A wind knife is set at one end of the frame, and the air outlet of the wind knife is set close to and parallel to the upper end surface of the steel belt. A soy milk input pipe is set on the side of the steel belt above the wind knife. The other end of the frame is located at the upper end of the steel belt and is provided with an L-shaped baffle with an adjustable angle that does not interfere with the silicone retaining edge. An inverted triangle recovery trough with an upper end close to the outer surface of the steel belt is provided at the tail of the other end of the frame, and a recovery bucket is provided at the lower end of the inverted triangle recovery trough.

[0018] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] The utility model provides a bean curd skin forming system for preparing bean curd sticks, as shown in the figure, including a conveyor and a heating device 5, both of which are prior art. For ease of understanding, it is stated that the conveyor includes a frame 1, an active roller 2, a driven roller 3, and a steel belt 4. The active roller 2 and the driven roller 3 are respectively arranged at both ends of the frame 1. The steel belt 4 is connected end to end after wrapping around the active roller 2 and the driven roller 3. The active roller 2 is connected to an external motor, and the motor works to drive the steel belt 4 to move cyclically through the rotation of the active roller 2. A device for pouring bean liquid onto the upper side of the conveyor is arranged, and the steel belt 4 is used to carry and transport the bean liquid. The heating device 5 is used to be attached to the steel belt 4, and the steel belt 4 is heated by heat exchange. The heating device 5 can be a steam heating device 5, an oil heat exchange device, and other devices, as long as the steel belt 4 can be heated. For example, the superheated steam water tank involved in the application publication number CN104824175A can achieve the heating of the steel belt 4 in this system.

[0020] The device also includes a main fan 8 and multiple air ducts 6. The air ducts 6 are used to dry and shape the soybean milk film on the conveyor belt through the blown air flow, so as to prompt the soybean milk film to form the skin of bean curd sticks more quickly. The peripheral wall of the air duct 6 is provided with multiple air holes connected to its inner chamber at intervals along its length direction. The multiple air ducts 6 are arranged on the frame 1 at intervals along the length direction of the conveyor. The air ducts 6 span the steel belt 4 and are located above the steel belt 4. The main fan 8 is the power source of the air duct 6. The main fan 8 is connected to any air duct 6 through a pipeline. When the main fan 8 is working, the air flow blown through the air duct 6 acts on the soybean milk on the conveyor belt, so as to prompt the surface of the soybean milk to dry and shape quickly.

[0021] The air holes of the air duct 6 are arranged obliquely toward the steel belt 4. Furthermore, the angle between the air holes of the air duct 6 and the conveyor belt is 10° in the conveying direction (soy milk flow direction) of the conveyor belt. Due to the angle between the air holes and the conveyor belt, the wind flow will not blow directly perpendicular to the material film, reducing the possibility of wrinkling or folding of the material film due to excessive wind force, making the wind flow softer when acting on the material film.

[0022] The pipeline includes a main pipe and multiple branch pipes. The main fan 8 is connected to the main pipe, the main pipe is connected to any branch pipe, and the multiple branch pipes are connected to the multiple air ducts 6 in a one-to-one correspondence.

[0023] As an optional implementation, the system also includes a plurality of auxiliary fans 7, which are arranged on the frame 1 along the length direction of the conveyor and are located on the upper side of the air duct 6. The air outlet of the auxiliary fan 7 is parallel to the conveying direction of the conveyor. The auxiliary fan 7 mainly provides auxiliary airflow parallel to the conveying direction to help the soy milk remain flat during the conveying process and prevent it from wrinkling or folding, thereby ensuring the molding quality of the bean curd sticks. The auxiliary fan 7 is arranged in the middle of the width direction of the conveyor.

[0024] In the above, the cooperation between the air duct 6 and the auxiliary fan 7 ensures that the airflow acts on the soybean milk more efficiently, thereby optimizing the drying effect.

[0025] As an optional implementation, a valve opened and closed by a controller is provided on any branch pipe to control the opening and closing of a single air duct 6 according to on-site needs, and the valve is set as a manual valve or a solenoid valve.

[0026] The working principle of this device is:

[0027] 1. Soy milk is laid on the steel belt 4 through the feeding pipe and enters the heating area as the steel belt 4 moves.

[0028] 2. The heating device 5 heats the steel belt 4 to start evaporating the water in the soy milk.

[0029] 3. At the same time, the airflow blown out by the air duct 6 acts on the soybean milk film to accelerate the crusting, and the auxiliary fan 7 provides parallel airflow to help the soybean milk film remain flat and prevent it from wrinkling or folding.

[0030] Under the action of heating and airflow, the soy milk film gradually dries and solidifies to form the skin of yuba. The system realizes continuous transportation of soy milk through the conveyor, and realizes the crusting of the soy milk surface through the cooperation of the heating device 5, the air duct 6, and the auxiliary fan 7.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
