Embodiment 1

[0032] The vitality liquid prepared in advance according to the formula while considering the characteristics of the fish is introduced into the frozen dormant liquid pool. The active liquid ingredients are: 0.01% chlorhexidine acetate, 6% sodium chloride, 15% ethanol, 10% glycerin, 3% chitin, 5% fructose, 2% sodium citrate, 0.1% of aspartate transcarbamylase, and the rest in distilled water. Turn on the dual refrigeration cycle coupling device, control the operating frequency of the cryogenic compressor according to the cell characteristics of the fish, and set the temperature of the vitality liquid in the frozen dormant liquid pool to -60 °C. Then put two fresh crucian carp into the low temperature pool. Taking advantage of the large temperature difference between the organism and the vitality liquid and the superior heat transfer performance of the vitality liquid, it only takes about 15 minutes for the crucian carp at normal temperature to be frozen to -20°C. At this tim...

Embodiment 2

[0034] The vitality liquid prepared in advance according to the formula while considering the characteristics of the fish is introduced into the frozen dormant liquid pool. The active liquid ingredients are: 0.05% chlorhexidine acetate, 18% sodium chloride, 5% ethanol, 5% glycerin, 5% chitin, 1% fructose, 1% sodium citrate, 0.5% of aspartate transcarbamylase, and the rest in distilled water. Turn on the dual refrigeration cycle coupling device, control the operating frequency of the cryogenic compressor according to the cell characteristics of the fish, and set the temperature of the vitality liquid in the frozen dormant liquid pool to -60 °C. Then put two fresh crucian carp into the low temperature pool. After about 15 minutes, the crucian carp was frozen and cooled to -20°C. At this time, the two crucian carp are already in a low-temperature dormancy period. Then put the two crucian carp in the freezer for 8 hours, take out the two crucian carp and thaw it in normal tempe...

Embodiment 3

[0036] Import the vitality liquid prepared in advance according to the formula while considering the characteristics of fruits and vegetables into the frozen dormant liquid pool. Vitality liquid component configuration: 0.01% chlorhexidine acetate, 8% sodium chloride, 15% ethanol, 6% glycerin, 3% chitin, 5% fructose, 1% sodium citrate, 0.2 % aspartate transcarbamylase and the rest in distilled water. Turn on the dual refrigeration cycle coupling device, control the operating frequency of the cryogenic compressor according to the characteristics of plant cells, and set the vitality liquid in the frozen dormant liquid pool to -35°C. The tomato seeds are then placed in a cold pool. Taking advantage of the large temperature difference between the organism and the vitality liquid and the superior heat transfer performance of the vitality liquid, the tomato seeds that were originally at normal temperature were frozen to -18°C after only about 4 minutes. At this time, the tomato se...

Abstract

The invention discloses an adjusting and controlling method and device based on vitality fluid and for quick frozen dormancy of organisms. The adjusting and controlling method comprises the following two steps of preparing the vitality fluid, and performing low-temperature dormancy treatment on the organisms through a double refrigeration cycle coupling device, wherein the vitality fluid is prepared from the following components in percentage by mass: 0.01-0.05% of chlorhexidine acetate, 6-18% of sodium chloride, 5-15% of ethanol, 5-10% of glycerine, 3-5% of chitin, 1-5% of levulose, 1-2% of sodium citrate, 0.1-0.5% of aspartate carbamyl transferase, and the balance being distilled water. According to the adjusting and controlling method and device based on the vitality fluid and for quick freezing and dormancy of organisms provided by the invention, the organisms can be in a frozen dormant state under low-temperature vitality fluid environment, and the optimal organism freezing storage is realized.

Description

technical field [0001] The invention relates to a low-temperature freezing technology of living organisms, in particular to a method and device for quick freezing and dormancy regulation of living organisms based on vitality liquid. Background technique [0002] Organisms are involved in the issue of antisepsis and preservation in the processes of food processing, grain transportation and storage, and drug preparation. One of the most commonly used anti-corrosion insurance technologies is low-temperature freezing technology, which means that organisms are directly placed in a cold storage for transportation, storage or processing. However, this process usually uses air as a medium to cool the organisms. Due to the low thermal conductivity of air, it takes up to several hours for organisms to cool from room temperature to the intended cryopreservation temperature. Long-term cooling increases the concentration and pressure difference between the inside and outside of the cel...
