In today's society, people's living standards are constantly improving, the pace of life is accelerating, and the limited time can not keep up with the increasing demand of people. Many people love food, but there are few people who have the time and interest in real hands. Therefore, cooked food products have emerged. More and more delicate food stores are appearing in people's sights, and there are various cooked food chains everywhere on the street. However, cooked food is often not easily preserved, and improper preservation is also prone to deterioration. The emergence of food vacuum packaging machines solved this problem. Food vacuum packaging machine can make the bag in a vacuum state to achieve sterility.
For meat products, deoxygenation can inhibit the growth and development of mold and aerobic bacteria, inhibit the oxidation of oil components, prevent deterioration of foods, and achieve preservation and shelf life.
For the fruit, the oxygen content in the bag is reduced, and the fruit is sparse. It produces carbon dioxide through anaerobic respiration while maintaining a certain humidity. This low-oxygen, high-carbon dioxide, and high-humidity environment can effectively reduce fruit transpiration and reduce fruit thinning. Breathing, reducing ethylene production and nutrient consumption, so as to achieve the purpose of preservation.
The scope of application of food vacuum packaging machines includes:
Pickled products: sausage, ham and some pickled vegetables, such as mustard, radish, pickles, etc.;
Fresh meat: beef, lamb, pork, etc.
Bean products: dried bean curd, bean paste, etc.;
Cooked products: beef jerky, roast chicken, etc.;
Convenient foods: rice, vegetables, canned foods, etc.
In addition to the above foods, it also applies to the preservation of pharmaceuticals, chemical raw materials, metal products, electronic components, textiles, medical supplies, and cultural materials. However, it should be noted that vacuum packaging is not suitable for packaging and preservation of fragile and brittle foods, sharp-angled plastic packaging bags, and soft and deformable foods.
The emergence of food vacuum packaging machines has provided conditions for the development and expansion of cooked foods, so that cooked food products are no longer subject to geographical and time constraints, and the development of dual wings to a broader space for development. In addition, food vacuum packaging machines are in line with the urgent need for novelty and rapid packaging in today's commodities, and promote the rapid development of the market economy. For producers, food vacuum packaging machines can fundamentally reduce the company's production investment, and achieve less investment and more revenue.
Sapphire glass. Similar to corundum, it has a hardness of 9. It can produce various colors by adding various chemical elements. The commonly used ones are colorless. It has the advantages of higher hardness and higher price than ordinary glass. It is mainly used to make high-end watch mirrors.
Germanium sapphire glass has good thermal properties, excellent electrical and dielectric properties, and is resistant to chemical corrosion. It has high temperature resistance, good thermal conductivity, high hardness, infrared penetration, and good chemical stability. Therefore, it is often used to replace other optical materials to make optical components, infrared-transmitting optical windows, and is widely used in infrared and far-infrared military equipment, such as: used in night vision infrared and far-infrared sights, night vision cameras and other instruments And satellite and space technology instruments and meters, as well as windows for high-power lasers, various optical prisms, optical windows, UV and IR windows and lenses, observation ports for low-temperature experiments, and high-precision instruments for navigation, aerospace, and aviation. Be fully applied.
For example, infrared transparent window materials, substrate substrates in the field of microelectronics, laser substrates, optical components and other applications.
