Intelligent vertical tank microwave sterilizer

Abstract

The invention discloses a vertical tank microwave sterilizer, and belongs to the technical field of microwave sterilization. The vertical tank microwave sterilizer comprises a tank, a microwave sterilization system and a material circulation system, wherein the tank comprises an upper seal head, a barrel body and a lower seal head which are sequentially arranged from top to bottom; a discharge port is formed in the bottom of the lower seal head, a feed port is formed in the upper seal head, and the material circulation system comprises a circulating pump and annular atomizing nozzles; the circulating pump communicates with the discharge port and the feed port through a circulating pipeline; the microwave sterilization system comprises a plurality of microwave generators and microwave windows corresponding to the microwave generators; the microwave generators are arranged on the outer wall of the barrel body in a rectangular array manner; the microwave windows are arranged on the innerwall of the barrel body; the annular atomizing nozzles are arranged on the inner wall of the top end of the barrel body; and the liquid spraying directions of the annular atomizing nozzles point to the surfaces of the microwave windows. The microwave windows and an annular multi-angle cross spraying device are arranged on the tank, so that a liquid material is sterilized at a relatively low temperature under the vacuum degree within a certain range, and the liquid material can be uniformly sterilized by microwaves.

Description

technical field [0001] The invention belongs to the technical field of microwave sterilization, in particular to a vertical tank microwave sterilizer. Background technique [0002] There are tunnel type microwave sterilization device and pipeline type microwave sterilization device in the prior art. Among them, the tunnel-type microwave sterilization device and the pipeline-type microwave sterilization device generally sterilize solid powder and packaged finished products, and the thickness of the materials on the conveyor belt should not be too thick. If the thickness exceeds 5mm, it will affect the quality of the powder materials. Sterilization effect. The tunnel type microwave sterilization device covers an area of ​​tens of meters, which is limited by site factors. [0003] In the existing liquid microwave sterilization device, due to the concentration of sharp angles of the electric field, the effective microwave action distance is short, and the liquid only flows in ...

Tunnel-type microwave sterilization device covers an area of ​​tens of meters, which is limited by site factors

[0003] The existing liquid microwave sterilization device, due to the concentration of the sharp angle of the electric field, the effective distance of the microwave is relatively short, and the liquid only flows in a small range in the sterilization device, so the microwave sterilization effect of the liquid material is not uniform
