Embodiment 1

[0021] A kind of manufacturing process of refrigerator of the present embodiment, its process step is as follows:

[0022] (1) Selection of box body and box cover material; choose a mixed polyethylene material of 90% high-density polyethylene and 10% low-density polyethylene as the material for making the box body and box cover, and the density of the high-density polyethylene is 0 .942g / cm3, said low-density polyethylene has a density of 0.890g / cm3;

[0023] (2) Box production: pour the materials selected in step (1) into the box mold to make the outer box. The box mold is 35cm long, 29cm wide, and 34cm high;

[0024] (3) Processing of the outer protective layer of the box; scrape the outside of the box clean with a scraper, and then paste it on the outside of the box with a 3.0mm thick Weigu heat insulation film, and then use a vacuum suction machine to suck it out for 5 seconds. 5 small air bubbles in the net membrane;

[0025] (4) Process the inner layer of the box; use ...

Embodiment 2

[0028] Example 2: The difference from Example 1 is that the density of the high-density polyethylene in the step (1) is 0.955g / cm3, the density of the low-density polyethylene is 0.905g / cm3, and the box is used in the step (2). The mold is 37cm in length, 31cm in width, and 35cm in height. In step (3), use Weigu heat insulation film with a thickness of 2.0mm to stick to the outside of the box, and then use a vacuum suction machine to suck for 10 seconds to remove 10 small air bubbles in the film. , In step (4), 28 small ice bag placement grooves are drilled around the inside of the box. The size of the placement grooves is 6cm long, 3cm wide, and 8cm high. In step (6), there are 11 finger-shaped rubber locks.

Embodiment 3

[0029] Example 3: The difference from Example 1 is that the density of the high-density polyethylene in step (1) is 0.965g / cm3, the density of the low-density polyethylene is 0.915g / cm3, and the box mold is used in step (2) The length is 38cm, the width is 30cm, and the height is 36cm. In step (3), use Weigu heat insulation film with a thickness of 4.0mm to stick to the outside of the box, and then use a vacuum suction machine for 15 seconds to remove 15 small air bubbles in the film. In step (4), 30 small ice bag placement grooves are drilled around the inside of the box. The size of the placement grooves is 5cm long, 3cm wide, and 7cm high. In step (6), there are 12 finger-shaped rubber locks.

[0030] Measured through experiments, put two pieces of fresh meat of the same weight in the refrigerator of the present invention and the common refrigerator on the market, and measure the volatile salts of the fresh meat in the two refrigerators after 12, 24, 36, and 72 hours respe...

Abstract

The invention discloses a manufacturing process of a refrigerated box, which is characterized in that the process steps are: (1) selection of box body and box cover materials; selection of mixed polyethylene with 90% high-density polyethylene and 10% low-density polyethylene The material is used as the material for making the box body and the box cover. The density of the high-density polyethylene is 0.942~0.965g / cm3, and the density of the low-density polyethylene is 0.890~0.915g / cm3; (2) box (3) processing of the outer protective layer of the box; (4) processing of the inner layer of the box; (5) production of reusable technological ice packs; (6) processing of the box cover and the lock of the box body; There are scientific and technological ice packs. Under the original refrigeration function of the refrigerator, reusable technological ice packs are added to double the cooling and freshness. At the same time, the protective layer of Weigu heat insulation film completely isolates the refrigerated items in the box from the outside infrared and ultraviolet rays, fully The original properties are preserved, and the process is reasonable and simple, which reduces the production cost and effectively improves the output of the enterprise.

Description

technical field [0001] The invention relates to a manufacturing process of fresh-keeping and refrigeration equipment, in particular to a manufacturing process of a refrigerator. Background technique [0002] In developed countries, fresh-keeping refrigeration equipment has been widely used in many fields since the 1970s. This kind of cold-keeping and fresh-keeping products produced by new technology has been gradually accepted by Asian regions due to its non-polluting environmental protection characteristics. And promotion and application, the consumer market is maturing day by day. With the improvement of people's quality of life, people's requirements for freshness and taste of various foods in life have also increased, and the efficiency of freshness preservation and refrigeration equipment has also attracted more attention. At the same time, medical sampling, sampling, refrigerated low-temperature transportation of biological agents, and blood transportation all require...
