The fresh-keeping cycle of the modified atmosphere packaging machine



The preservation period of the modified atmosphere packaging machine is inseparable from the characteristics of the food itself, the pre-cooling process of the food, the temperature of the environment, the residual oxygen content, etc., so how long the modified atmosphere packaging can be kept fresh is a comprehensive problem, and it cannot be explained independently of the modified atmosphere packaging. Under normal circumstances: when the pre-cooling process of the food is well handled, the ambient temperature is effectively controlled, and the performance of the machine is guaranteed, the general fresh-keeping period of cooked food is 12 to 15 days. Fruits and vegetables vary according to the ingredients. For example, strawberries can be stored for more than 15 days, cherries can also be stored for more than 12 days, and frozen meat can be stored for 7 to 9 days. The key point of modified atmosphere packaging is the pre-cooling process of the food. If the pre-cooling process is not done properly , causing the number of colonies at the front end to exceed the standard, such ingredients themselves are not fresh, so after using modified atmosphere packaging, the number of days of freshness will also be greatly discounted. Time placement, we have done corresponding experiments. Under the same conditions as the front end, one adopts modified atmosphere packaging and the other is ordinary sealed packaging. Under the condition of direct sunlight at 25 degrees Celsius for 2 hours, the number of colonies in the modified atmosphere packaging box and the ordinary sealed packaging There is no obvious difference, indicating that the effect of modified atmosphere packaging is not very obvious under normal temperature conditions. Therefore, another core of modified atmosphere packaging is the configuration of the whole process of cold chain system. If customers want to use modified atmosphere packaging products, the cold chain system It must be considered, otherwise the effect of modified atmosphere packaging will be greatly reduced.


For equipment, there are two main points that affect the fresh-keeping period of modified atmosphere packaging machine products, one is the residual oxygen content, and the other is the mixing accuracy of the gas. The performance of the equipment is also an important guarantee for the preservation period of the ingredients. To sum up, the preservation period of the modified atmosphere packaging is not an independent problem, it is composed of many key parts, so the overall planning must be carried out to do a good job in the modified atmosphere packaging , Only in this way can the expected effect be achieved. Shanghai Jixin Packaging Machinery Co., Ltd. has advanced process equipment, excellent design team, professional production organization, comprehensive quality control system, and ensures the safe and secure use of each customer.
