Why are stretch film vacuum packaging machines more and more popular now?
author：
In the era when the stretch film vacuum packaging machine is particularly popular, the vacuum packaging machine as a packaging machine, its packaging forms are also very diverse, which is more conducive to the sales of products, it can adapt to various types of products. The vacuum packaging machine is more popular , it still has more room for development. A vacuum packaging machine is a process used to draw air in a vacuum bag and then seal it to create a vacuum that separates packaged items. Oxygen, fresh-keeping, moisture-proof, mildew-proof, anti-corrosion, anti-corrosion, insect-proof, pollution-proof, etc., effectively prolong the shelf life and shelf life of the product, and make it more convenient for transportation and storage. Several new technologies have been added to the vacuum packaging machine, such as air key low temperature drying technology, concentrated vacuum impregnation technology and impregnation-dehydration double food vacuum processing technology.
1. Vacuum critical low-temperature drying technology: vacuum critical low-temperature drying technology is a technology that processes various agricultural and sideline products drying products through a heating system under vacuum conditions close to vacuum freeze-drying, and the critical conditions for product color change and nutrient loss are . This technology can not only effectively improve the production efficiency, but also improve the preservation effect. Generally, dehydrated vegetables, fruits and vegetables, dehydrated Chinese herbal medicine, tea and compound fruit tea, dried flowers, dried meat, various dried and fresh fruits, such as walnuts, chestnuts, peanuts, seeds, etc. all use this vacuuming technology.
2. Concentrated vacuum impregnation technology: Concentrated vacuum impregnation technology refers to the use of vacuum low temperature concentration mechanism to prepare impregnated working fluid, such as sugar solution or salt solution, in an oxygen-deficient and low temperature environment. According to the process requirements, the segmentation and reinforcement processing technology of various candied fruit, preserved fruit, pickled products and high-quality concentrated juice can be realized. This machine has a good vacuum and anti-oxygen atmosphere, and the heating mechanism has a wide heating range. It can not only realize low-temperature segment concentration operation, but also process cooked meat products and food to be processed with higher temperature. The dipping process can be done in one operation without changing position. Since the immersion liquid is used in an oxygen-deficient protective atmosphere, the biological properties remain well and can be reused after addition.
3. Dehydration double food vacuum processing technology: This is a technology combining concentrated vacuum impregnation technology and vacuum critical low temperature drying technology. Using agricultural products as raw materials can effectively improve the quality and operation of various foods. The time is short, the processing variety is wide, and it is not limited by the production season of agricultural products, and can achieve balanced production throughout the year. The scope of application is all kinds of fruit and vegetable potato chips, dehydrated fruit and vegetables, dried fruit, dehydrated Chinese herbal medicine, dried flowers, tea and compound fruit tea, fruit powder and concentrated fruit juice, and various meat products.
