Low-frequency alternating electric field generating apparatus and system, and signal conditioning method

Abstract

The invention provides a low-frequency alternating electric field generating apparatus and system, and a signal conditioning method, which belong to the field of biomass fresh keeping devices. The low-frequency alternating electric field generating apparatus comprises a DC (direct current) power supply module, an input control module, a transformer, an output control module and a discharging module. An output end of the DC power supply module is coupled with an input end of the input control module, an output end of the input control module is coupled with a primary winding of the transformer, one end of a secondary winding of the transformer is coupled with an input end of the output control module, an output end of the output control module is coupled with the discharging module, and the other end of the secondary winding of the transformer is coupled with a ground-end equipotential point. A generated low-frequency alternating electric field can enables water molecules in fresh keeping biomass in the low-frequency alternating electric field to generate swinging of the same frequency, inhibits biochemical reaction and physiological metabolism, achieves a good fresh keeping effect, and also can accelerate the biomass freezing speed in a low-temperature environment.

Description

technical field [0001] The invention relates to the field of biomass preservation equipment, in particular to a low-frequency alternating electric field generating device and system, and a signal adjustment method. Background technique [0002] With the development and improvement of science and technology, electric power technology has been applied to the field of biomass preservation. Food or agricultural products can get a better fresh-keeping effect after being passed through static electricity or placed in an electrostatic field. [0003] In the prior art, the biomass can be contained in a container made of conductive material, and the container is placed on a metal stand connected to an electrostatic power supply to obtain a fresh-keeping effect. However, since the fresh-keeping benches and storage and fresh-keeping facilities of this technology require excellent insulation to ensure the safety of high-voltage use, the production cost and maintenance cost of this tech...

AI Technical Summary

Problems solved by technology

However, this technology also faces the cost and safety problems of insulation facilities

At the same time, under high voltage, the raw material tissue cell membrane of fresh-keeping biomass is easily broken down by high voltage, and then after the fresh-keeping treatment is lifted, it will accelerate the corruption and deterioration

In addition, the existing technology also faces high technical requirements for the required power supply equipment, which seriously restricts the convenience of its practical application.
