Embodiment 1-4

[0027] S1: mix the mineral salt and the thickening regulator according to the distribution ratio of the parts by weight in Table 1 to obtain the mixture (A);

[0028] S2: adding the nucleating dispersing anti-caking agent to the above mixture (A), stirring at a high speed to make it fully mixed to obtain the content (B);

[0029] S3: Pack the above content (B) to obtain a non-zero phase transition point self-filling ice bag (C).

[0037] Experimental Example 1: Application of water-filled ice packs of the present invention in keeping beef fresh

[0038] Experimental material: frozen beef

[0039] Experimental treatment: 250g of frozen beef is packed in a packaging bag, and then placed in a foam box together with 1000g of self-injected water ice packs with a phase change point of -22.3° of Example 4 that has been injected with water and frozen. The control group is 1000g of zero-degree phase change ice packs , and the rest of the conditions are the same. The foam box containing the beef was placed at room temperature for 3 days. After three days, the beef deterioration rate of the experimental group was 11.3%, and the beef deterioration rate of the control group was 33.5%.

[0040] The invention provides a simple, cheap, non-toxic, non-zero-degree ice pack preparation process, which can be filled with water when used, shaken well or put into a freezer to freeze before use, which solves the problem of hi...

Abstract

The invention discloses a preparation process, a using method and application of a non-zero-degree phase change point self-water-injection ice bag. The preparation process of the ice bag comprises thefollowing steps: taking 2-15 parts by weight of mineral salt and 1-5 parts by weight of a thickening regulator, adding 0.5-5 part by weight of a nucleation dispersion anti-caking agent, stirring at ahigh speed, uniformly mixing to obtain an ice bag coolant dehydration formula, and packaging into a water injection ice bag to obtain the self-water injection ice bag with the non-zero-degree phase change point. When the ice bag is used, 80-96.5 parts by weight of water can be automatically injected into the contents of the ice bag, and the ice bag can be used after being shaken up or left to stand for 5-20 minutes and frozen for 10-24 hours. The ice bag prepared by the process can be applied to article transportation. According to the preparation process of the non-zero freezing point self-water-injection ice bag, the problems that the ice bag transportation cost is high and no self-water-injection ice bag with a non-zero phase change point exists on the market are solved.

Description

technical field [0001] The invention relates to an ice pack, in particular to a preparation process, use method and application of a non-zero phase transition point phase change self-filling water ice pack. Background technique [0002] With the development of online shopping and the express delivery industry, more and more merchants choose to sell or express fresh food such as fruits and vegetables, fish, meat, chicken and duck, or biological preparations online. Under the condition of cold storage and preservation in ice packs, it is possible to express the above-mentioned items. The preservation temperature required for various refrigerated foods is different, such as: meat products below 0°C; vegetables around 4°C; fresh agricultural products 0-18°C; biological pre-products 2-8°C. However, to express the above-mentioned food, the ice pack needs to be kept at the above-mentioned corresponding temperature within a period of 2-3 days. [0003] In the prior art, during the...
