Problems solved by technology

However, this technology has higher requirements on the power and specifications of the compressor, and requires a lot of energy consumption.
At the same time, most of the existing magnetic field freezing technologies use the static magnetic field of permanent magnets, the one-dimensional alternating magnetic field of electromagnets or Helmholtz coils for auxiliary freezing, and the technical parameters are single and the magnetic field distribution in the freezing area is extremely uneven, which is easy to Causes differentiated freezing effects, and the product quality varies greatly after thawing

Abstract

The invention discloses an energy-saving type multi-dimensional magnetic field auxiliary freezing system based on program controllability and application of the energy-saving type multi-dimensional magnetic field auxiliary freezing system. The energy-saving type multi-dimensional magnetic field auxiliary freezing system based on program controllability comprises a freezing unit, a multi-dimensional alternating magnetic field unit and a control unit, wherein the freezing unit comprises a freezing area used for containing freezing samples; the multi-dimensional alternating magnetic field unit comprises at least two magnetic excitation coil sets, the at least two magnetic excitation coil sets are used for forming at least two alternating magnetic fields in different dimensional directions, and the at least two alternating magnetic fields are intersected at least in the freezing area; and the control unit is at least used for adjusting and controlling the work state of the freezing unit and the multi-dimensional alternating magnetic field unit. By means of the energy-saving type multi-dimensional magnetic field auxiliary freezing system based on program controllability, needed energy is lower when the samples reach the same freezing quality, and the processing amount is larger.

Description

technical field [0001] The invention particularly relates to an energy-saving multi-dimensional magnetic field assisted freezing system based on program control and its application, which belongs to the technical field of preservation of food, agricultural product raw materials and medical samples. Background technique [0002] The freezing preservation of organisms including various foods, aquatic products, flour products, fruits and vegetables and agricultural products is to suppress the respiration inside the samples at low temperature, weaken their metabolism and enzyme activity, and control the growth and reproduction of microorganisms at the same time, so as to realize the preservation of samples. preservation. In the temperature range of -5°C to 1°C, most of the water in the organism is frozen and forms ice crystals, so this temperature region is called the maximum ice crystal formation zone. Therefore, the moisture state inside the sample will change dramatically in...
