Introduce the causes and solutions of air leakage in vacuum composite bags.aluminium coffee bag

1、 The bacterial growth inside vacuum composite bags often produces gas, which is one of the reasons for food bagging.

The solution is as follows:

1. Control the initial microorganisms of the raw materials. Minimize the degree of contamination of raw materials as much as possible, strictly select raw materials, and avoid using the principle of contamination and spoilage to avoid product spoilage and bag swelling caused by excessive microbial residues.

2. Improve the quality of staff, enhance their awareness of quality control, establish a comprehensive quality management system, actively promote quality control activities, and fully leverage the subjective initiative of staff. Improper operation by staff can increase food pollution and cause bagging.

3. The raw material processing processes of each processing process should be closely coordinated, and the shorter the transfer connection time, the better. There should be operating standards for processing time, processing temperature, and pickling time to ensure the production of qualified products. On the other hand, the time from product cleaning and disinfection to semi-finished products should be minimized to reduce microbial pollution. Otherwise, bacterial residue and growth may occur, leading to bagging.

4. Ensure timely sterilization after vacuum sealing, ensure timely sterilization of products after vacuum sealing, facilitate smooth logistics, strictly follow the operating procedures of sterilization process, improve the control, maintenance, and quality inspection skills of operators, and avoid secondary pollution of finished products; Regularly check the operation performance of the sterilization machine, abandon the sterilization machine with functional problems, or conduct detailed investigation and strict correction of the reasons.

5. Check if the high-temperature sterilization time and temperature sterilization time are insufficient, the temperature cannot meet the standard, and the temperature is uneven, which can easily cause microbial residue and growth. Thus, microorganisms can decompose organic matter in food, producing gases such as hydrogen sulfide and carbon dioxide. If there is gas in the vacuum composite bag, it will cause the problem of bag expansion. Most of the bagging problems in our food industry are not related to the sterilization temperature. So, before processing and production, it is necessary to check whether the temperature meets the standards and frequently check the thermometer. The sterilization process must control the time well, improve the quality of the staff, and do not artificially shorten the sterilization time in order to improve work efficiency. Uneven sterilization temperature requires changing the use of equipment or modifying the equipment.

6. The topic of hygiene control, temperature and humidity control in the production workshop will be discussed again next time. My opinion is that if there is no air purification equipment, try to use Whole-house fan to circulate air.
