Sterilization machine

Abstract

The invention relates to a material sterilization machine, in particular to an electrically-heating continuous sterilization machine, which comprises a trough (17), a helical blade (7) in the trough (17), a power source (16), conductive plates (15), contact plates (4) and insulating plates (5). The power source (16) and a left shaft end (6) and a right shaft end (14) of the helical blade form an electric circuit through the conductive plates (15) and the contact plates (4). The left shaft end (6) and the right shaft end (14) of the helical blade are connected with the trough (17) through the insulating plates (5). By using the sterilization machine, continuously conveyed materials inside a closed space can be electrically heated and sterilized. The sterilization machine is effective in sterilization, high in efficiency, low in cost, and stable and reliable in performance.

Description

technical field [0001] The invention relates to a material sterilizing device, in particular to a continuous sterilizing machine using electric heating. The invention belongs to the technical field of sterilization equipment. Background technique [0002] The continuous sterilizer is a device that takes crushed or powdered solid materials as raw materials, and heats and sterilizes them during the transportation process. It can be used as a sterilization equipment for industries such as food, medicine, biological products, feed and additives. , It can also be used as other process production equipment that needs to heat and sterilize crushed or powdered materials. [0003] The continuous sterilizer commonly used at present uses steam as the heat source to heat and sterilize the continuously transported materials. For example: Chinese patent announcement number CN2855102Y discloses a sterilizer, which includes a box body with an upper part provided with a material inlet and...

AI Technical Summary

Problems solved by technology

The main problem: a large amount of steam needs to be introduced, the steam consumption is large, and the final moisture content of the material is difficult to control; in addition, the product needs to be dried again, which increases energy consumption and equipment investment

Its main disadvantages: the heating device is to heat the shell of the conveyor, and the material is then exchanged with the shell of the conveyor. The heat energy is transferred from the outside to the inside, the heat transfer efficiency is low, the heat loss is large, and most of it is dissipated in the air , and the material heating uniformity is low
