Problems solved by technology

[0003] Although freezing and refrigerating technology has been greatly developed in recent years, even under freezing and refrigerating conditions, the preservation of objects is still limited. Furthermore, cooling down and improving the storage environment will greatly increase the cost of preservation, especially for preserved items with relatively low economic benefits
Due to the long-term airtightness of many cold stores and freezers, the air flow is poor, and there are a large number of germs or ethylene and other ripening gases suspended in the indoor air. These gases will affect the stored items and reduce the insurance effect.

Abstract

The invention relates to a freshness-preserving method and equipment, and in particular relates to a biological enzyme active freshness-preserving device and a method thereof. Combined with an alternating-current field and low-frequency vibration, the bonding state of internal water molecules of objects preserved in a large electric field space and enzyme activity are changed, thereby achieving the effects of inhibiting bacteria growth and protecting cell tissues; and for eliminating surplus positive charges, a negative ion generating device or a special rare earth mixed material is also utilized for generating negative ions, thereby achieving a neutralizing effect. A photocatalyst in the biological enzyme active freshness-preserving device can effectively decompose ethylene and other organic gas under photocatalysis and simultaneity kill bacteria and viruses in air. The biological enzyme active freshness-preserving device can effectively prolong the freshness-preserving period of green vegetables, fruits, meat and seafood, can change the water crystallization behavior to generate fine and smooth ice crystals to play a protective role on cells, and can be applied to each link of a cold chain for improving the freshness-preserving and freezing quality and decreasing the wastage rate.

Description

technical field [0001] The invention relates to a fresh-keeping method and equipment, in particular to a biological enzyme activity fresh-keeping device and a method thereof. Background technique [0002] The cold chain refers to certain food raw materials, processed food or semi-finished products, special biological products and pharmaceuticals after they are purchased, processed, sterilized and inactivated, during the process of product processing, storage, transportation, distribution, retail and use. , its various links are always in the specific low-temperature environment necessary for the product, reducing loss, preventing pollution and deterioration, and ensuring the special supply chain system of product food safety, biological safety, and drug safety. The main environment of the cold chain is for example: frozen food, chilled fresh processing workshop; large cold storage; refrigerated and frozen transportation; blood bank, cell preservation warehouse, tissue preser...
