How to choose a modified atmosphere packaging machine:
1. It must have a high-precision gas automatic mixing device, and its precision control requirements are accurate. The maximum error rate should be ≤2.0%, and the ideal state is ≤1.0%. Accuracy testing of different mixing ratios of the three gases is necessary.
2, must have a higher gas replacement rate, the higher the replacement rate, the better the preservation effect, the ideal replacement rate ≥ 99.5%.
3. Manufacturers of composite modified atmosphere packaging machines must fully understand the knowledge related to food preservation.
Composite atmosphere preservation is a multi-link, multi-field technology integration. Therefore, manufacturers of composite modified atmosphere packaging machines must have a rich and comprehensive study on the characteristics of foods and vegetables, pretreatment processes, food processing environments, equipment combinations, packaging materials and operating procedures. If the manufacturer has no control over the characteristics of the food, what about food preservation? As a new product, the hybrid modified fresh-keeping packaging machine has just come out. Its many technical knowledge and consumers are not very clear. Therefore, in addition to purchasing qualified equipment, customers should also request equipment manufacturers to provide full technical support. Ensure that the customer's products achieve the preservation effect.
4. Must have high-quality R&D manpower and research team.
Whether the company has development potential and how to guarantee the quality of the products, all of which require high-quality R&D personnel and professional research teams. Without these as the backing, whether the quality of the products can pass the customs and whether they can win the trust of consumers, there is a certain Question. Therefore, when purchasing products, we must not only look at the price and appearance of the products, but also pay attention to the inherent quality of the products and the research and development capabilities of the production companies.
5. The rationality and quality reliability of the air-conditioning fresh-keeping packaging machine is also a necessary prerequisite for selection.
The modified atmosphere packaging machine is mainly used for food preservation packaging, and the number of bacteria in the packaging environment and packaging materials has a great influence on food preservation. Therefore, the use of stainless steel and anti-corrosion materials is a must. In addition, since the heat seal film roll may take up to several days to be used up in the actual production process, it is easily contaminated by bacteria, so that the heat seal roll film is placed in a closed environment and is not suitable for sterilization by ultraviolet rays or ozone.
6. Before purchasing gas-conditioning equipment, it is necessary to observe and comprehensively compare and avoid losses caused by mis-purchasing unqualified products.
