Liquid material microwave high pressure rapid heating sterilizing device

Abstract

The invention discloses a liquid material microwave high pressure rapid heating sterilizing device. The device comprises a sterilizing oven, a feeding inlet and a communicating vessel, wherein the sterilizing oven adopts a hollow structure; the side wall of the sterilizing oven is connected with a high pressure pump through a pipeline; the high pressure pump is connected with the outer side wall of the sterilizing oven through connecting block threads; a material inlet is formed in the upper end of the sterilizing oven. The liquid material microwave high pressure rapid heating sterilizing device is simple in structure, and can realize high temperature sterilization through the adding of an electric heating plate and a microwave generator inside the heating furnace, meanwhile as a materialloading bent pipe in the material inlet adopts multistage bending arrangement, the microwave generator produces microwave, the microwave enables polar micromolecule in materials to rapidly vibrate andheat the materials through rapidly vibrated electromagnetic wave, can rapidly heat relatively viscous materials and liquid materials with more suspended solids, can convey the materials, and the sterilizing device integrates double heating during high temperature short-time sterilization, and improves the production efficiency.

Description

technical field [0001] The invention relates to the fields of bioengineering, medicine, food, and chemical industry, in particular to a microwave high-pressure rapid heating and sterilization device for liquid materials. Background technique [0002] With the continuous development of science and technology, microwaves are used in various fields. Microwaves refer to electromagnetic waves with frequencies in the range of 300MHz to 300GHz. They were first used in military radar and communication fields. Later, people discovered that using microwaves to irradiate objects will produce thermal effects. Rapidly increase the temperature of the irradiated object. This characteristic of microwave has been widely used in industries such as food and medicine, and has entered the family in large quantities, and its microwave generator and corresponding control technology have been relatively mature and perfect.

Problems solved by technology

[0003] The traditional steam heating and sterilization method is not only complicated in heating equipment, but also takes a long time in heating, heat transmission loss is large, operation is troublesome, the process is complicated, and energy consumption is also high. It is quite difficult to realize automatic and intelligent online heating control. , high cost of operation and equipment operation; heat sterilization of materials using microwave is one of the best choices to replace traditional sterilization methods, and has the advantages of simple equipment, easy operation, low energy consumption, and less loss of heat-sensitive substances

However, in the actual production process, in order to improve production efficiency, the heating effect brought by only a single high-temperature heating or microwave heating cannot meet the needs of mass production, and it takes a long time. Therefore, a microwave high-pressure rapid heating method for liquid materials is proposed. Heat Sterilizer
