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

Abstract

A low-temperature sterilization apparatus and method, said apparatus comprising a microwave device (5), said microwave device (5) being provided with a microwave chamber (7) producing a sterilizing microwave radiation source; said apparatus further comprising a container (1) located inside the microwave chamber (7); said container (1) being provided with a feed port (3) and a discharge port (4). An interlayer (12) is provided on the outer side of the container (1), said interlayer (12) being provided with a fluid inlet (13) and a fluid outlet (14); said interlayer (12) being internally provided with a fluid; said fluid being a liquid mixture containing microwave-absorbing material. The method is: material entering via the feed port (3) said container (1) inside the microwave chamber (7); the mixed solution containing microwave-absorbing material being guided into the interlayer (12) via a fluid inlet (13), forming an externally arranged microwave-absorbing layer for sterilizing the material. The microwave radiation exerts an effect on the microwave-absorbing layer and the material layer, thereby regulating the thickness of the material layer; when sterilization has been completed, the material is discharged via the container discharge port (4).

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...
