To improve the sealing of tin boxs, need to isolate the contact between air and food, so that tin boxes can be used to store items well.
1. High temperature heating exhaust.When packaging meat products, high temperatures of 80-90 degrees Celsius are generally used to quickly exhaust and seal in a short period of time.Fruit and vegetable products should use long-term exhaust methods at 60-75 degrees Celsius until a proper vacuum is achieved in the tank.
2. Vacuum compressed air.When the food is about to be sealed, it is placed in a special vacuum sealing machine, which uses the pressure in the vacuum to compress the air in the can.Vacuum processing can also avoid the residue of bacterial microorganisms. This method is not limited by food heating and is one of the methods currently used.
3. Steam drives away air.This method quickly sprays steam into the packaging to drive out the air in the tank. After the air is discharged, the steam in the tube is condensed to achieve a vacuum effect.This method is more economical and convenient, but is subject to product applicable restrictions.
As long as the tin box packaging pays attention to isolating air and water, the storage time and quality preservation effect can be extended.Tinmen United one-stop tin boxes solution,Quick Custom,Free Design Service, We can supply free accessories,such as PE bag,heat shrink film and craft tie.
