Embodiment 1
[0038] The special cold storage agent embodiment for cold chain takes kilogram as the unit, and contains 100 grams of potassium chloride, 5 grams of sodium carbonate, 1 gram of silicon dioxide, and 5 grams of sodium carboxymethyl cellulose in every kilogram of special cold storage agent for cold chain of the present invention. The rest is water.
[0039] The cold storage agent for cold chain of the present invention comprises the following processes during preparation:
[0040] A. Heat the water to about 50°C and keep it at this temperature;
[0041] B, weigh potassium chloride, sodium carbonate, sodium carboxymethyl cellulose by weight, slowly drop into water after mixing, stir while adding, form uniform viscous solution;
[0042] C. Finally, slowly add silicon dioxide to make it evenly dispersed in the solution, and then obtain the cold storage agent specially used for cold chain.
