What are the common sterilization methods for aluminum easy-open lids?

　　Aluminum easy-open lidThere are four common sterilization methods for canned fruits: steam, side spray, top spray, and sand bath. Each of these common sterilization methods has its own advantages and disadvantages. The side spray sterilizer is specifically developed for items with inflated packaging bags. The heating method involves heating or cooling the sterilized items through side spray cooling circulating water. Since almost all cooling circulating water is sprayed simultaneously, the temperature received by goods in different locations is the same, and the issue of temperature asymmetry can usually be ignored. During the entire operation of the side spray sterilizer, the capacity of the cooling circulating water and the goods in the can is less than 50%, and most of the indoor space is steam. Therefore, it is very easy to adjust the working pressure inside the sterilizer, which means that the working pressure inside the aluminum easy-open lid sterilization can be precisely operated according to the set specifications, which is very beneficial for inflating aluminum foil packaging bags.

The method of full water sterilization pot, due to the specific gravity of water usually exceeding that of sterilized food, and the aluminum foil packaging bag being filled with rare gases, the items remain in a floating state throughout the sterilization process. The overlapping placement of goods threatens the circulation of cooling circulating water, thereby threatening the symmetry of heat transfer. Since 95% of the indoor space of the sterilizer is occupied by goods and water, it appears that the back pressure control fluctuations during the entire sterilization process of the full water sterilizer are significant and have a long linearity.

How to identify if the aluminum easy-open lid can has gone bad?

With the acceleration of life pace, people tend to prefer "fast food" in their daily lives. Canned drinks play an indispensable role in our daily lives due to their "quick and time-saving" characteristics. Supermarkets offer various styles of canned food, and as a regular on the dining table, the food quality of aluminum easy-open lid cans should be given more attention. So how can we eat healthy and clean canned food?

1. First, pour the contents of the can onto a plate and observe the condition of the can itself. If the tin can shows signs of inner coating peeling, oxidation rings, or sulfide spots, it indicates that there are certain quality issues with the can, which should be taken seriously.

2. Next, check the color and smell of the food in the can. For example, whether the fruit can is yellowed, whether the meat can has normal color, and whether the food in the can has an off smell. If it differs from normal conditions, it is a sign that the can has gone bad.

3. Then, take a small taste of the food in the can to see if there are any sour, lazy, or rotten off-flavors. If there are, you should throw away the can.

Through the above three steps, we can roughly judge whether the can in hand has gone bad.Aluminum easy-open lidFood is the primary need of the people, and food safety is paramount. To ensure the high quality of canned food, strict quality control is implemented on the production of metal easy-open can lids and cans, striving to protect the food quality and health of users.
