Contact plate freezer adopts double-faced contact quick freezing way.It is the method which can load food in the metal mold,with the top and bottom metal plate which use as an evaporator clamping upon it and passes over the refrigeration working substance directly to transmit cold to products.Because the conductivity of metal is ten times higher than air,it can make products' quick-freezing.This method has characteristics as below:
Shor freezing time and quick freezing quality,it is the best choice for massive food quick-freeze.
High heat exchange efficiency,quick freezing speed,the energy conservation effect is prominent.
Ensure food obtains the high quality as well as lower the cost to minimum.
The unit is high flexibility and vast range of application. When you use the product in stipulation molding,first put the product in the horizontal multilayer evaporator,then make the product contact impinge on evaporator.The row temperature of the refrigeration circulative pass in the evaporator can transmit cold to product quickly,and get quick-freezing.
Horizontal plate freezer makes the product into pieces,which is an economic and high efficient freezing method.It can adjust the distance of plates and compaction grade base on product.It suits for packed fish,shrimp,seashell,meat,and mixed food;vegetable,fruit,boxed cooked food,any bag or tray packed cake and easy molding products.
The TPF series plate freezer's standard composition is as follow's:
Cabinet,base frame,multilayer plate evaporator,liquid supply pipe,gas out pipe,hauling carriage hydraulic device and electric control system.
TPF series plate freezer is suitable for many kinds of refrigeration systems,ammonia and freon is commonly used.In order to adapt to the environmental protection request,TPF series plate freezer is also suitable for more environmental protection refrigeration.
Ammonia refrigeration system:
Liquid supply and gas out all in one plate,short course and small resistance is better than plates pump liquid supply.It has higher and even freezing speed,quicker defrosting.
Freon refrigeration system:
Two plates use one liquid supply and gas out system.Set expansion valve on each system to ensure the even of each system.
Adopting stainless steel bellows for liquid supply and gas out pipe,which connect with evaporator,it can ensure long time operation in low temperature.
The collected pipes use stainless steel material,which can ensure the requirement of food security and sanitation.
