Non-uniform electric field liquid sterilization processing chamber

Abstract

The invention discloses a non-uniform electric field liquid sterilization processing chamber. According to the non-uniform electric field liquid sterilization processing chamber, an inner electrode and an outer electrode are arranged coaxially and vertically, and a non-uniform electric field is formed between the inner electrode and the outer electrode; liquid flows into the sterilization processing chamber from the upper part of the sterilization processing chamber and passes through an insulation liquid separation ring to form a thin liquid film on the outer surface of the inner electrode; and the liquid is sterilized by the electric field formed between the inner electrode and the outer electrode while flowing downwards along the outer surface of the inner electrode under the action ofgravity, and the sterilized liquid flows out of the processing chamber. According to the non-uniform electric field liquid sterilization processing chamber, the liquid is sterilized uniformly by utilizing the non-uniform electric field; and the non-uniform electric field liquid sterilization processing chamber has a simple structure and a good sterilizing effect, and is convenient to manufacture.

Description

Technical field [0001] The invention relates to a sterilization treatment chamber, in particular to a sterilization treatment chamber that uses an electric field to sterilize liquid objects in the food, biological, pharmaceutical, chemical and other industries. Background technique [0002] Electric field sterilization technology is to apply high-voltage electricity to two electrodes to form a high-voltage electric field between the two electrodes. The bacteria-carrying liquid flows between the electrodes. The electric field destroys the bacterial cell membrane (wall) and promotes the death of bacteria to achieve sterilization. Its advantages are that the sterilization time is short, the temperature rise is small, and the sterilization effect is obvious. Non-heat sterilization can be achieved for liquid food, and it has almost no effect on the color, aroma, taste and nutrient content of the food, which has attracted widespread attention in the world. [0003] The existing electric...

AI Technical Summary

Problems solved by technology

[0003] The existing electric field liquid sterilization treatment chamber can be divided into two categories, one is the uniform electric field liquid sterilization treatment chamber, mainly parallel flat plate electrodes and coaxial cylindrical electrodes (the radius of the inner and outer electrodes is close, and the approximate uniform electric field), its advantages It is uniform sterilization, but the disadvantage is that the electric field strength is not high, the sterilization rate is low, the electrode spacing is small (usually about 0.001-0.01m), the liquid flow resistance is large, and the energy consumption of liquid flow is large

The second is the non-uniform electric field liquid sterilization treatment room, mainly needle-type and linear electrodes, which have the advantages of high electric field strength in some local spaces and high local sterilization rate, but the disadvantage is that the electrodes are easy to discharge and the sterilization is not uniform
