DETAILED DESCRIPTION

[0028] 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.

[0029] The utility model provides a continuous production and forming system for bean curd sticks, as shown in the figure, including a crusting device, a slurry flow device 4, a peeling and cutting forming device, a drying device, a cleaning device, and a drying conveyor 7, wherein:

[0030] The crusting device comprises a crusting conveyor 1, a heating mechanism 2, and an air conveying mechanism 3.

[0031] The crust conveyor 1 is an existing device, including a frame, an active roller, a driven roller, and a steel belt. The active roller and the driven roller are respectively arranged at both ends of the frame. The steel belt is connected end to end after wrapping around the active roller and the driven roller. The active roller is connected to an external motor through a coupling. The motor works to drive the steel belt to circulate through the rotation of the active roller. The slurry flow device 4 is arranged above the starting end of the crust conveyor 1, and the cleaning device is arranged at the end of the crust conveyor 1 and below the crust conveyor 1.

[0032] The heating mechanism 2 is essentially a heat exchanger, which transfers and exchanges heat energy through different media (such as steam, oil, etc.) to achieve the purpose of heating. As long as the steel strip can be heated, the superheated steam water tank involved in the application publication number CN104824175A can achieve the heating of the steel strip in this system. For ease of understanding, the present application specifically describes a structure of a heating mechanism 2. The heating mechanism 2 includes a steel plate attached to the inner side of the upper steel strip of the crusting conveyor 1, and a steam coil 203 is opened in the steel plate. A liquid inlet 201 and a liquid outlet 202 connected to the external steam coil 203 are opened on the side wall of the steel plate. A steam hole 204 connected to the steam coil 203 is opened on the upper wall of the steel plate. The liquid inlet 201 is connected to the output pipe of an external steam source (such as a steam boiler). The steam is transported from the steam source to the liquid inlet 201 through a pipe, and then enters the steam coil 203 in the steel plate, thereby achieving heating of the steel plate. The liquid outlet 202 is connected to an external condensate recovery system or drainage system. When the steam is heated in the steel plate and then cooled to form condensate, the condensate is discharged through the liquid outlet 202 and can be recycled or safely discharged. The setting of the steam hole 204 enables part of the steam to be discharged from the steam hole 204 to between the steel strip and the steel plate to form a water film to play a lubricating role.

The air holes of the air ducts are inclined toward the steel belt. The main fan is connected to any air duct through a pipeline so that the main fan can work and supply air into any air duct to blow toward the soy liquid on the crust conveyor 1, thereby prompting the soy milk film to form the skin of the bean curd sticks faster.

An annular groove is provided on the peripheral wall of the forming disc 6. The straight rod spans the conveyor belt of the drying conveyor 7 and is rotatably arranged on the frame of the drying conveyor 7. The third motor is connected to the straight rod through a coupling so that the third motor drives the straight rod to rotate. Both the forming disc 6 and the circular cutter 5 are provided in plurality, but the forming disc 6 and the circular cutter 5 are arranged in an alternating manner.

[0037] The drying device includes a pre-drying device, which includes a drying chamber 8 and a heat exchange fan 9. The drying chamber 8 has passage openings for a drying conveyor 7 at opposite ends.

The scraper 1001 is against the end of the crust conveyor 1, and the scraper 1001 is tilted downward and away from the steel belt of the crust conveyor 1. The end of the scraper 1001 against the conveyor belt is defined as the liquid inlet end, and the other end of the scraper 1001 opposite to it is defined as the liquid discharge end. The scraper 1001 is tilted to the steel belt so that the height of its liquid inlet end is higher than the height of the liquid discharge end. A collecting trough is provided below the liquid discharge end of the scraper 1001 so that the material on the conveyor belt can flow out into the collecting trough along the scraper 1001 after being scraped by the scraper 1001. Furthermore, the scraper 1001 includes a base plate and a guide plate which is at an obtuse angle to the base plate. The base plate is inclined and matched with the conveyor belt, and the guide plate is arranged horizontally.
