Between two adjacent fixing machines, the first discharge door 21 of one fixing machine is adjacent to the second discharge door 22 of the other fixing machine, and the adjacent first discharge door 21 and the second discharge door 22 are connected by a discharge door connecting piece 23. The discharge door connecting piece 23 is connected to the discharge door electric push rod 19, so that the adjacent first discharge door 21 and the second discharge door 22 can be synchronously raised and lowered along the discharge door slide rail under the action of the discharge door electric push rod 19.

[0055] The transmission assembly 9 is used to drive the actuators of multiple green-fixing machines to perform stir-frying actions synchronously. Specifically, the transmission assembly 9 includes a driving motor 24 and six groups of synchronous primary chain transmissions 26 connected to the six actuators of the six green-fixing machines. A primary chain transmission reducer 25 is also provided between the driving motor 24 and the primary chain transmission 26.

The primary chain transmission 26 is arranged on one side of the green-fixing system. Every two green-fixing machines are driven by a synchronous chain. The outermost two green-fixing machines use ordinary single-link sprockets, and the inner four green-fixing machines use double-link sprockets.

[0056] The temperature control component is used to monitor the internal temperature of the pot body 10 and control the internal temperature of the pot body 10 within a set range. Specifically, the temperature control component includes a temperature sensor 33 and a heating device arranged at the lower part of the pot body 10.
