Green preparation system for food deoxidizer

The green preparation system comprises a calcining furnace, a high-temperature fan and a nitrogen pump, a fireproof plate is fixedly embedded in one side of the calcining furnace, one end of a connecting pipe is fixedly installed on the side wall, on the periphery of the fireproof plate, of the calcining furnace, and the other end of the connecting pipe is fixedly connected with the air inlet end of the high-temperature fan; the air outlet end of the high-temperature fan is fixedly connected with one end of an air inlet pipe, the other end of the air inlet pipe communicates with a high-temperature heat exchange mechanism, the high-temperature heat exchange mechanism comprises a machine shell, a plurality of partition plates are fixedly installed in the machine shell, and communicated hollow inner cavities are formed in the machine shell and the partition plates. And the released heat can increase the temperature in the calcining furnace, the energy required for reheating is reduced, the reduction of energy co
