Aquatic product fresh keeping device based on high-voltage alternating electric field

Abstract

The invention discloses an aquatic product fresh keeping device based on a high-voltage alternating electric field. The device comprises a program control wide-frequency-band multi-waveform signal generator, a high-frequency transformation-ratio adjustable transformer, a safe resistor, an electric field generator and a storage cabinet body, wherein the electric field generator is positioned in thestorage cabinet body; the electric field generator is arranged at the upper end and the lower end of the storage cabinet body by using a rotary or swinging structure, so that the regular crossing coverage of the electric field in the storage cabinet is formed; meanwhile, the storage cabinet body is of a flow guide open electric field type structure, so that an electric field structure realizing fluid guide treatment and electric field full coverage in the storage cabinet is formed. The field intensity generating device for generating the alternating field intensity uses a rotary structure; the uniform coverage of the electric field intensity in a certain range is ensured; the fact that the fresh keeping effect of partial aquatic products is affected due to the insufficient field intensitycoverage is avoided.

Description

technical field [0001] The invention relates to a fresh-keeping device, in particular to an aquatic product fresh-keeping device based on a high-voltage alternating electric field. Background technique [0002] The use of high-voltage alternating electric field to keep aquatic products fresh is a major fresh-keeping method in the food preservation industry at present. High-voltage alternating electric field preservation has no thermal effect, minimal energy consumption, small increase in food temperature, and basically no impact on the quality of food itself, etc. It is a widely used physical preservation method. When aquatic products are kept fresh, the transmembrane voltage of the cell membrane will increase under the action of an external electric field, and micropores will be formed on the membrane when it exceeds its own dielectric strength; if the transmembrane voltage exceeds the critical value, the micropores will become larger, and the cell membrane will perforate u...

Problems solved by technology

However, in practical application, we found that there will always be some aquatic products whose preservation effect is not satisfactory compared with most of the aquatic products that are preserved together. After analysis, we found that the original electric field generating device and aquatic products were kept static Moving, some products on the edge are not covered by sufficient voltage field strength, so the preservation effect is compromised
