Tea tin be familiar to everyone, but it must be used correctly and reasonably to ensure that it will not bring security risks. The following are safety requirements for using tin cans. Presumably there are still many users who want to know. You can find out briefly in the following article. Hope to help you!
Tea tin use safety requirements:
1. Before the cans are used, they should be sprayed with a mortar or a dry slag, and there should be no accumulated water, moist debris and flammable and explosive materials inside the cans;
2. The trunnion of the tin can should be forged and its safety factor should not be less than 8;
3, trunnion wear more than 10% of the original shaft diameter, that should be scrapped; annually deal with the trunnion for a nondestructive inspection, make records, coexist.
The prospects for the development of cans and drums in the market are very impressive. Although in daily life we will see many different specifications and shapes of iron products and will use them again, this does not mean that we have a very good understanding of cans and iron drums. The following will briefly explain the characteristics of tin packaging for everyone.
1, not opaque, in addition to the light will cause food after the bad reaction, but also cause changes in protein and amino acids. Vitamin C is more easily exposed to light and makes it more effective with other food ingredients, causing many to be thrown away. According to the analysis of the flash, the clear glass bottles of milk, the amount of vitamin C thrown away 14 times higher than the dark bottled milk, the light will also cause oxidation odor of milk, as well as nuclear, methionine and other cracking and throw away nutrients The value, the opaque tin cans make Vitamin C very safe.
2. Sealability The barrier properties of packaging containers to air and other volatile gases are important for the storage of nutrients and sensory quality. Comparison of various juice packaging containers proves that the oxygen permeability of the container directly affects the browning of juice and the storage of vitamin C; the storage of metal cans, glass bottles and aluminum foil laminates with low oxygen permeability, and cartons preserves vitamin C better.
3, tin recovery effect, the tin of the inner wall will be filled with oxygen in the container when filling effect, reduce the chance of oxidation of food ingredients. The recovery effect of tin is excellent for the taste and color of light fruit and fruit juices. Therefore, the use of unpainted Tea tin provides better storage of nutrients in juice cans than other packaging materials. The taste quality is better tolerated and the shelf life extends.
Through the introduction of the above information, we learned that can packaging can create a space that is insulated, sealed, and opaque for the goods, to prevent the goods from being affected by external factors, in order to facilitate better and longer storage. It is precisely because of these advantages of can packaging, in order to win the recognition of many users, has been widely used.
