Multi-layer tunnel microwave drying sterilizer

Abstract

The invention discloses a multi-layer tunnel microwave drying sterilizer, and relates to the technical field of microwave drying sterilizing. The problem that an existing microwave drying sterilizingdevice needs to be additionally provided with a cooling device to conduct cooling after carrying out drying sterilizing on food raw materials is mainly solved. The multi-layer tunnel microwave dryingsterilizer comprises a base, the base is provided with a supporting column, the supporting column is connected with a connection block, and the connection block is fixedly connected with a ferrule; the interior of the ferrule is provided with two limiting blocks, and an installing groove is arranged between the two limiting blocks; the ferrule is connected with a cooling barrel, the cooling barrelis provided with an installation block, and the installation block cooperates with the installation groove; the other end of the cooling barrel is connected with a hydraulic cylinder, the interior ofthe cooling barrel is provided with a stirring barrel, and the stirring barrel is internally provided with an output shaft; and the output shaft is rotationally installed through an installation frame, stirring rods are uniformly arranged on the output shaft, and the output shaft is connected with a first motor.

Description

technical field [0001] The invention relates to the technical field of microwave drying and sterilization, in particular to a multi-layer tunnel type microwave drying and sterilization machine. Background technique [0002] In the process of food production, in order to ensure the effective drying and sterilization of raw materials, microwave drying and sterilization technology is usually used. Microwave drying technology is an internal heating method, that is, during the microwave drying process, the wet material is placed in a microwave high-frequency electric field with a very short oscillation period, and its water molecules rapidly rotate with the alternating direction of the high-frequency alternating electric field, resulting in violent As a result, part of the microwave energy is converted into molecular kinetic energy, which is expressed in the form of heat, and the temperature of the water is raised to leave the material, thereby achieving the drying effect.

Problems solved by technology

On the other hand, in the microwave alternating electromagnetic field, the bacteria have a strong electrical response, and the cell membrane of the capacitive structure is broken down; at the same time, the ion channels that the bacteria rely on for their survival have a serious disorder in the regulation function, resulting in the death of the bacteria

[0003] After the existing microwave drying and sterilization equipment processes the food production raw materials, the temperature of the food raw materials is high, which is not conducive to the next step of food processing. Generally, an additional cooling device is required to cool down, which increases the operation process and the number of equipment
