With the attention of the public and health issues, especially the food safety and health issues criticized by the public in recent years, the safety situation is worrying. In order to better control food safety and health problems, China has also issued laws and regulations to supervise, restrict and punish the illegal acts of "food safety and health law", and meet the requirements of relevant food production norms.
In order to prevent the whole process of food production from being polluted by microorganisms, the raw materials, water, equipment and other places must be treated. Whether the environment of production workshop is clean is also an important condition. In addition, some foods require clean sterile production environment, such as the following industries need to do air purification workshop engineering.
Aseptic treatment is often used in the processing of yoghurt, aseptic milk or cheese, and in the packaging of sausages in Sweden. Some large facilities require more than 100000 levels (ISO 8 and 9).
Filling (liquor, beverage, etc.)
啤酒、果汁和汽水无菌填装工艺增加了ISO 5级(100级)和ISO 6级(1,000级)洁净室。
ISO 5 (100) and ISO 6 (1000) clean rooms were added for beer, juice and soda aseptic filling process.
In the traditional system, the tunnel pasteurization method is used to treat the products at various high temperatures, and the physical properties of the products are changed. In contrast, using lower heat treatment for controlled pasteurization can improve the quality of products in several aspects.
The food produced in the clean workshop, because of its high cleanliness, can ensure that the food is not attached by bacteria, but can not eliminate the bacteria brought by the food itself, so it also needs heating, spraying, irradiation and other ways of sterilization. Many purification workshop projects are mainly used for cooling, cutting (piece), packaging and other processes after sterilization.
