Abstract

The invention discloses a coaxial structural uniform flow cavity for sterilization of a high voltage pulse electric field. The coaxial structural uniform flow cavity comprises two uniform flow cavities which are symmetrically arranged and an electrode arranged between the two uniform flow cavities, wherein the electrode comprises a ground electrode which is fixedly connected with the two uniform flow cavities and a high-voltage electrode which is axially connected with one uniform flow cavity; a coaxial sealing cavity is formed between the ground electrode and the high-voltage electrode; one circle of small holes are formed in each uniform flow cavity along the axial line and are communicated with the coaxial sealing cavity; one transitional cavity is connected to the outer end face of each of the two uniform flow cavities. According to the coaxial structural uniform flow cavity disclosed by the invention, a sterilizing effect of the high voltage pulse electric field is further improved by adopting a high-voltage electrode leading mode and the design of the uniform flow cavities, and the treatment efficiency of the sterilization of the high voltage pulse electric field is effectively improved.

Description

technical field [0001] The invention relates to the field of high-voltage pulse sterilization, in particular to a coaxial structural uniform flow chamber used for high-voltage pulse electric field sterilization. Background technique [0002] As a new type of non-thermal sterilization technology, high-voltage pulsed electric field (Pulsed Electric Fields, PEF) sterilization has the advantages of high instantaneous treatment intensity, short time, and small thermal effect, and will not destroy the original components in the treated samples, and can maximize It is a non-thermal sterilization technology with broad application prospects to preserve sensory indicators such as flavor and color of samples to the maximum extent. Its working principle is to place the sample to be processed in a processing chamber that generates a high-voltage electric field, and to achieve the effect of killing microbial cells by applying high-voltage electric pulses. A large number of experimental r...
