2020/08/08
Many food companies according to their own products, need hot food vacuum packaging, such as vacuum packaging machine is also need special structure to heat sealing products.



are generally required cooled to room temperature for packaging. According to the theory, with a higher thermal vacuum degree of vacuum, thermal packaging easy to control the total bacterial colonies ( Subsequent sterilization thoroughly, there is no advantage) But depends on the product type, for example, do some dumplings, all is the requirement of cold packaging, mainly cold packaging can reduce the water content of rice dumplings. Other products also should according to the characteristics of the product to choose, generally most of the products or room temperature packaging, packaging process is very difficult to operation, because of the heat measured basic now or by hand is in the bag. After high temperature vacuum packaging vacuum degree of vacuum is not normal temperature is high, easy to leak.


then heat sealing products will have an impact on routine packaging machine vacuum pump? Naturally, as a result of thermal vacuum will take a lot of water vapor, if is the oil seal of the vacuum equipment used, the large amounts of water into the vacuum pump, vacuum pump oil and mix together, it is easy to overflow, 2 it is vacuum pump oil easy to scrap.



the principle of normal temperature food vacuum packaging is: because food metamorphism causing mold mainly caused by the activity of microorganism, and most microorganisms ( Such as mold and yeast) Survival is need oxygen, and vacuum packing is using this principle, the packaging and food within the cell oxygen smoke, lose micro physical & other; The survival of the environment & throughout; 。 Experimental results show: when the concentration of oxygen in the packaging & le; 1%, microbial growth and reproduction rate fell sharply, oxygen concentration & le; 0. 5%, most microbes will be reined in and stop breeding. ( Note: vacuum packing can inhibit anaerobic bacteria breeding and enzyme reaction caused by food metamorphism and discoloration, so still need to combine with other auxiliary methods, such as cold storage, frozen, dehydrated, high temperature sterilization, irradiation sterilization, microwave sterilization, salting, and so on. )



so the customer is according to the needs of their products to buy suits own vacuum packaging machine.
