The operation of each part of the whole machine is balanced and reliable, the action is coordinated and continuous, and the electronically controlled air control system is sensitive and reliable. The production line is single-machine control, and the system consisting of the main control component programmable controller (PIC) uses imported gas ovens. The whole metal structure of the furnace body has good thermal insulation performance and beautiful appearance. Each temperature zone has an observation window to facilitate product process inspection, burner redesign, advanced energy-saving combustion technology, greatly improved thermal efficiency, uniform furnace temperature and heating quality. Well, the heat source costs are low, which extends the life of the equipment. This equipment is the most important equipment for the wafer production line. It consists of 45 pairs of baking sheets (taking 45 molds as an example), variable speed FM motor and reducer transmission, grouting system, baking sheet gas heating system and gas leakage alarm device. The furnace output is connected to the cake device and other systems. When the oven is working normally, the baking tray runs to the outside of the mold opening rail, and the slurry is uniformly injected into the baking sheet through a row of small holes of the nozzle. The upper and lower baking sheets are closed and automatically locked, and the slurry is dried into a white yellowish cake under high temperature.
