Food thawing and preservation, high voltage electrostatic thawing/preservation technology, the most core part is the thawing cabinet electrostatic High voltage generator.
We've known for a long time that cold is good for preserving food, but when the refrigerator came along, we marveled at what a great invention it was -- a way to extend the shelf life of food in a more efficient way, not just by freezing it, but by freezing it. And when we take frozen food out of the freezer, how do we defrost it quickly and well? Foods that need to be thawed are mainly frozen meat, poultry, seafood, etc.
At present, the cold chain logistics system in our country is not perfect. Cold chain distribution of raw meat still has the problem of broken chain, and frozen meat becomes meat.The main body of product circulation. Frozen meat should be thawed before terminal sales and secondary deep processing, which is unreasonable. It is easy to affect the quality of thawed meat, and it is easy to produce color degeneration, fat oxidation, dehydration and protein degradation in the thawing process.
At present, frozen meat in meat stores mostly uses natural thawing in room temperature storeroom or water thawing. These thawing methods have low operating costs. However, slow thawing speed, high SAP loss rate, easy to produce microbial reproduction pollution, there are food safety hazards and other difficulties to be solved Question.
Since the 1990s, domestic and foreign scholars have proved through experimental studies that high voltage electrostatic thawing is a new thawing technology with high efficiency, synchronous and uniform thawing of meat and food, low nutrient loss rate, effective improvement of the color of frozen meat, and has an inhibiting effect on bacteria and can improve the quality of meat. Improve thawing efficiency and quality of frozen meat.
High voltage electrostatic power supply for meat preservation have the following functions
1. The reason why the high voltage electrostatic field can accelerate the thawing of ice is that the micro-energy generated by the high voltage electrostatic field can accelerate the breaking of hydrogen bonds in the ice structure, making the ice exist in the form of small ice crystals, and then gradually transition to the liquid state of small molecules of water.
2 Form ionic wind
There will be charged particles in the high voltage electrostatic field, and these charged particles will move in different directions due to their different charges. Negatively charged particles will move in the direction of the positive plate, while positively charged particles will move in the direction of the negative plate. The movement between such particles will form ionic wind. The thawing speed is closely related to the shape of the electrode, in which the thawing effect of the plate electrode is not obvious, and the thread electrode and needle electrode can obtain a larger thawing speed, mainly because the needle electrode and wire electrode have relatively strong electric field tip, the scattered charged particles in the air will accelerate under the action of the strong electric field, colliding with the air molecules to form new charged particles. This creates a flood of charged particles, creating more ionic winds in the electric field, which speeds up thawing.
3 Produce negative ion effect and ozone effect
Studies have found that the high voltage electrostatic field can ionize air to generate negative ions and ozone, negative ions can inhibit the metabolism of biological tissues, reduce the intensity of respiration, slow down the activity of enzymes and other effects; Ozone can react with the lipid double bond of bacterial cell wall, penetrate into the interior of bacteria, act on proteins and lipopolysaccharides, and change the permeability of cells, thus leading to the death of bacteria. Danyang and Lyritt studied the ozone generation capacity of high voltage electrostatic field, and the study showed that with the increase of electric field intensity, the ozone content also increased, and the high voltage electrostatic field proved that the ozone generated has a certain inhibition and killing effect on bacteria.
We have been ordering High voltage electrostatic generator module from Jiangsu Tianwang
Tianwang has a self -built plant, with more than 30 years of experience in developing high voltage electrostatic module. The main products are: high voltage modules, ignition transformers, high voltage pulse generators, electrostatic generator power supply, plasma ion generators, etc. After many years of hard work and support from customers at home and abroad, the electrostatic generator module have been continuously updated and improved. At present, the company has developed into a manufacturer with the most large scale high voltage electrostatic module production, manufacturing, research and development, and trade.
