Heating and dissolving device for sodium propionate production and use method of heating and dissolving device

The invention belongs to the technical field of sodium propionate production, and discloses a sodium propionate production heating and dissolving device which comprises a reaction cylinder and a lower grinding disc, a sleeve block is fixedly connected to the top of an inner cavity of the reaction cylinder, a motor and a supporting frame are fixedly connected to the top of the reaction cylinder, and a first gear is fixedly connected to the output shaft end of the supporting frame; an inner cavity in the top of the supporting frame is in threaded connection with a two-way threaded rod. Through cooperation of an upper grinding disc, a lower grinding disc, a conical grinding disc, a spline shaft and other structures, the device has the effect of grinding sodium carbonate so as to increase the reaction speed, sodium carbonate is put in from a feeding hopper, meanwhile, a motor is operated, and the reaction speed is increased. At the moment, the sodium carbonate enters the position above the upper grinding disc in
