Low temperature sterilization equipment and method thereof

Abstract

The invention discloses low temperature sterilization equipment and a method thereof. The equipment contains a microwave machine which is provided with a microwave cavity for generating a sterilization microwave radiation source. The sterilization equipment also comprises a container arranged inside the microwave cavity. The container is equipped with a feed inlet and a discharge port. An interlayer is disposed outside the container. The interlayer is provided with a fluid inlet and a fluid outlet. A fluid is arranged in the interlayer. The fluid is a mixed liquid containing microwave absorbing material. The method contains the following steps: a material enters the container arranged in the microwave cavity from the feed inlet; the mixed liquid containing the microwave absorbing material is guided into the interlayer through the fluid inlet to form an external wave-absorbing layer of a sterilized material, and temperature control can be carried out through the fluid; The microwave radiation acts on the wave absorbing layer and a material layer; the mixed liquid of the wave absorbing layer also absorbs part of heat energy of the sterilized material so as to adjust thickness of the material layer as well as material temperature; and the material is discharged out of the discharge port of the container after sterilization.

Description

technical field [0001] This patent belongs to the field of sterilization, and specifically relates to a microwave low-temperature sterilization equipment and method. Background technique [0002] Microwave sterilization is a non-thermal and thermal-effect integrated sterilization method, which belongs to the category of low-temperature sterilization and is mainly used in biology, medicine, chemical industry, food and other fields. Due to the strong penetrating power of microwave radiation, its application is extremely wide. In the prior art, microwave sterilization of materials generally adopts the following forms: [0003] First, the sterilizing radiation source provided directly irradiates and sterilizes the unshaped accumulation material. Because the microwave sterilization effect is related to the thickness of the material accumulation, the sterilization method is not uniform and the sterilization effect is unreliable. It is only suitable for the sterilization of soli...

AI Technical Summary

Problems solved by technology

[0015] In microwave sterilization, for some special materials such as viscous materials, if you want to keep the repeatability and controllability of the sterilization process for such materials, the use of general tube and conveyor belt methods will cause difficulties in loading and unloading. Therefore, it is necessary to find suitable technical means
