The fully automatic spray sterilization pot isInject a small amount of process water to reach the predetermined position (without soaking the product), and then inject the water into the spray pipe through the circulation pump filter heat exchanger. Then, spray the hot water in an atomized form onto the surface of the food through the spray nozzle. The heat distribution inside the pot is uniform and there are no dead corners for sterilization. Water is heated and cooled through a heat exchanger, with rapid heating and cooling rates, which can stably sterilize the product.
