[0016] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The utility model provides a bean curd skin forming device of a bean curd stick forming machine, as shown in the figure, comprising a conveyor and a steel plate 1 attached to the inner side of the upper conveyor belt of the conveyor. The conveyor is a prior art. For ease of understanding, it is now stated that the conveyor comprises a frame, an active roller 7, a driven roller 8, and a steel belt 6. The active roller 7 and the driven roller 8 are respectively arranged at both ends of the frame. The steel belt 6 surrounds the active roller 7 and the driven roller 8 and is connected end to end. The active roller 7 rotates to drive the steel belt 6 to move. A device for pouring bean liquid onto the conveyor is arranged on the upper side of one side of the conveyor, and the steel belt 6 is used for carrying and transporting the bean liquid.

[0018] The steel plate 1 is arranged on the frame, and the upper wall of the steel plate 1 is in contact with the inner side of the upper steel belt 6 of the conveyor. The conveyor works to sequentially make the parts of the steel belt 6 contact with the steel plate 1 for heat conduction, thereby heating the soybean liquid on the steel belt 6. A steam pipe is provided in the steel plate 1, and a liquid inlet 4 and a liquid outlet 5 connected to the steam pipe are provided on the side wall of the steel plate 1. A steam hole 3 connected to the steam pipe is provided on the upper wall of the steel plate 1, and the steam pipe is provided as an S-shaped coil.

[0019] The liquid inlet 4 is connected to the output pipe of an external steam source (such as a steam boiler). Steam is transported from the steam source to the liquid inlet 4 through a pipe, and then enters the steam pipe in the steel plate 1, thereby heating the steel plate 1. The liquid outlet 5 is connected to an external condensate recovery system or drainage system. When the steam is heated in the steel plate 1 and then cooled to form condensate, the condensate is discharged through the liquid outlet 5 and can be recycled or safely discharged.

[0020] Furthermore, the steam hole 3 is vertical and connected to the steam pipe, and the position of the steam hole 3 on the upper wall of the steel plate 1 is set to face the end of the steam pipe where the soybean liquid is put into the steel belt 6. When the steam enters the steam pipe from the steam source through the liquid inlet 4, the steam is sprayed toward the inner side of the steel belt 6 through the steam hole 3, so that the arrangement of the steam hole 3 can form a water film between the steel belt 6 and the steel plate 1, which plays a lubricating role and reduces friction and wear.

[0021] As an optional implementation, an advection groove perpendicular to the conveying direction of the steel strip 6 is provided on the upper wall of the steel plate 1, and the advection groove is connected to the steam hole 3. The design of the advection groove enables the steam ejected from the steam hole 3 to form a uniform steam layer in the groove. Since the advection groove is perpendicular to the conveying direction of the steel strip 6, the steam can cover the width direction of the steel strip 6 when flowing in the groove, ensuring that the steam can act on the steel strip 6 evenly.

[0022] Alternatively, a plurality of steam holes 3 are provided, and the plurality of steam holes 3 are arranged at intervals in a direction perpendicular to the conveying direction of the steel belt 6 .

[0023] 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.
