France has developed a new technology for long-term preservation of goods
for example, a company in France has developed a new technology for long-term preservation of goods that should not be lower than the specified value of cold drawn carpet steel wire grade B. Put the articles into a cubic plastic bag made of polyethylene (the capacity of the bag to continue to participate in distilled water is 1100 liters and the weight is 12 kg), and then send the bag into a vacuum chamber that has completely extracted air and water. The automatic device can block the pores on the surface of the bag. Using this method to preserve the deformed or fallen cement, grain, coffee, flour, cheese, dried fruits and other items, two years later, they are still intact, and the quality is not affected at all, such as grains, which are neither infested nor moldy
