Abstract

The invention belongs to the technical field of food sterilization and particularly relates to continuous powder damp and hot sterilization equipment. The continuous powder damp and hot sterilization equipment comprises a spraying sterilization device, a separation device and a drying device, wherein the spraying sterilization device comprises a venturi spraying device; the venturi spraying device is provided with a high-temperature steam inlet, a powdery material feeding hole and a mixing chamber; the mixing chamber is connected with a mixing pipe; the mixing pipe is internally provided with a mixing cavity; the mixing pipe is communicated with the separation device; and the separation device is communicated with the drying device. The continuous powder damp and hot sterilization equipment provided by the invention adopts a damp and hot sterilization manner; and compared with existing microwave sterilization and irradiation sterilization manners, the continuous powder damp and hot sterilization equipment has the advantages of simple and reasonable structure, small investment, low cost and short sterilization time; and the quality of powdery materials is not damaged, the continuous production is realized and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of food sterilization, and in particular relates to a continuous powder moist heat sterilization equipment. Background technique [0002] Food sterilization is to take food raw materials and processed products as the object, through the main factor that causes food deterioration - the sterilization and sterilization of microorganisms, to achieve the stabilization of food quality, effectively prolong the shelf life of food, and thus reduce the survival of harmful bacteria in food Quantity, to avoid human (usually intestinal) infection caused by the intake of live bacteria or human poisoning caused by bacterial toxins produced in advance in food. Existing food sterilization methods are various, but microwave sterilization methods and radiation sterilization methods are mainly used for powder food sterilization methods. [0003] The microwave frequency used in microwave sterilization is 2450MHz. The research r...
