The following specification particularly describes the invention and the manner in which it is to be performed.
Field of the Invention
This invention relates to the field of industrial machinery, and more particularly to an industrial freezer used in a factory.

Background of the Invention
Machines for cooling and freezing of articles, such as foodstuffs are known in the prior art. Example freezer in the factory often affects the quality of the product due to poor freezing effect, and different types of products cannot be effectively classified and refrigerated.
Conventional machineries, generally comprise elongated freezing tunnels through which articles to be cooled and frozen are passed, generally on a moving belt or other conveyor means. Long, narrow cooling and freezing tunnels are necessary for effective cooling requirements, yet allow for long contact times for articles or foodstuffs to be cooled or frozen. Some freezers generally rely on manpower to place the goods on the shelves when moving the goods into the freezer. When they need to be placed on the shelf high, they also rely on manpower, which consumes labor greatly and has low work efficiency. Most existing freezers rely on humans to manually lock them.
Proper balance of food in the freezing system is important, but can be difficult to maintain throughout continuous production of the food products. In general, conventional freezers does to some extent but they are pressurising entire cabin which again leads limitation on the variety of products in a single day production. Even they if they do on variety of products they have to go for defrosting process which eventually affect the efficiency of the production and also power consumption.
There are no known automatic methods, system or a machine which ensure a freezing of variety of products and stay "balanced" throughout production. To ensure maximum operating efficiency, the freezer must be constantly monitored and adjusted manually in order to maintain the necessary operating balance, especially where perishable products, such as food products are processed.
There is therefore provided a freezer system which automatically balances a freezer throughout production, relieves the operator from the burden of "balancing" the freezer, and provides higher overall efficiencies for the freezing system without limiting on the variety of products in the conveyor.

Object of the invention
