Airtight packaging, or Quick freeze machine, is a new innovation that makes it possible to quickly freeze food in bulk. The process of using this machine involves placing food into a can, then covering it with an outer case of plastic. A trigger is fitted in the can, activating the heating element that causes the can to be instantly frozen. The outer case of the plastic then rapidly releases freezing air to the inner contents of the can. The inner core of the plastic remains cold. Quick freezing (individual quick freeze) is faster than traditional quick freeze because individual frozen crystals of ice don't break down the cell structure of the food as with slow freeze.
Airtight sealed can packaging of frozen food is ideal for food service equipment such as food centers, retail shops, hospitals, drug stores and other distribution centers. In addition, it can also prevent spoiled food from spoiling while keeping the freshness of the food. These new types of packaging methods are used to preserve foods in bulk. As compared to the conventional methods, quick freeze machine results in much lower food loss, unneeded spoiled food, and less food waste. These advantages result in higher profit margins for food service centers.
There are many benefits associated with the quick freeze machine. The first advantage is the preservation of the foods at low temperature for long term storage. It can also prevent food loss due to spoilage, especially in cases where the quality of frozen food can be compromised by rapid freezing. Since the inner contents of the can are frozen, it is prevented from absorbing the flavor of the other food contents stored within the can.
The second advantage of quick freeze machine is its capability to provide a controlled low temperature freezer environment. This ensures that all the chemicals, nutrients, and vitamins in the food are well preserved, while its outer surface is left unopened for a longer time period. In addition, the tunnel type freezing devices and the contact type freezing devices can maintain a consistent freezer environment, which makes it suitable for industrial, commercial and laboratory activities. With the help of these types of freezing machines, a large number of different types of food items can be preserved, which includes perishable, frozen, dried, powdered, pickled, and processed food products. Another advantage of these machines is that they do not require too much energy, which can save on the operating costs. However, it must be ensured that adequate insulation is present near the freezer to protect it from overheating.
The third advantage of using the quick freeze machine is the convenience it provides for the end users. The quick freeze products can be purchased conveniently in different sizes and capacities. Depending on the requirements, individuals can purchase one of the sizes that best meets their requirements. Also, the quick blast types, which are available in small, medium, and large sizes, can be used for freeze drying perishable or pre-prepared foods, dried beans, ground beef, fish, poultry, meat, vegetables, and fruits. The low temperature that is maintained due to the generation of low voltage energy, makes it possible for these products to be stored in appropriate quantities, for a longer time period.
The final advantage is that the production capacity of these fasteners is large enough to meet the demands of different food productions. The freezer like the metal or aluminum ones are capable of holding thousands of pounds of products. On the other hand, the cryogenic freezers, which are popularly used for refrigeration purposes, can hold up to several hundred pounds of frozen products. The rate at which these types of freezers work, ensures that foodstuffs are kept in an organized manner. They can also be used in various food processing operations, including meat cutting, dairy processing, bakery, pharmaceutical manufacturing, pulp and paper production, and others.
