What are the specific usage methods of the ice box purchased? In fact, the use method of the ice box is the same as that of the ice bag. Their differences lie in the packaging materials between them. Generally, the packaging materials of the ice bag are nylon laminated film or PE film. The ice box is made of HDPE, which is more durable than the ice bag in the process of weekly transportation, but the cost is much higher than the ice bag. Moreover, the ice box is made of solid materials. It is hard and equipped with anti bulge structure, so it is not easy to bulge and deform, and its shape is regular. When it is frozen, it is placed more casually than ice bag.

How to use the ice box:

(1) before using the ice box, we need to check the ice box to see whether it is in good condition, whether there is leakage, whether there is stain, etc.

(2) after the first inspection of the ice box, it is necessary to find out what the temperature type of the ice box to be frozen is, whether it is refrigerated or frozen, and then select the appropriate freezing equipment to freeze the ice box. In general, the freezing equipment has strong freezing capacity, the number of frozen ice boxes is appropriate, and the ice box can be charged and cooled in 12-24 hours.

(3) before putting the ice box into low-temperature distribution, we need to check whether the ice box has been completely filled with cold. The identification method is to see whether the contents of the ice box are completely solid. If so, it can be put into use. If not, it needs to continue to be filled with cold. It can be used after it is completely frozen.

(4) after checking that the ice box is completely frozen, we will put the low-temperature articles into the insulation box matching the ice box size, put the specified number of ice boxes around the low-temperature articles, cover the cover of the insulation box and seal well, that is to say, the use of the ice box will be completed.
