The Crust Freezer freezes the outer bottom layer of the product, which is in direct contact with the belt, preparing the product for a variety of freezing applications such as slicing/cutting operations. The Crust Freezer can also be used for various other applications such as avoiding belt marks on products prior to entering the main IQF Freezers and increasing capacities for existing IQF Freezers.
The products are placed on a thin Teflon belt and gently led through the freezing zone. Cooling plates are mounted under the belt ensuring a fast crust freezing of the products “underside”. The freezing zone is built into a fully welded insulated stainless steel cabinet. Pneumatically hoistable insulated cover, for easy cleaning and maintenance. Sea water resistant Aluminum Freezing plates for efficient Heat Transfer.
The unit is equipped with fans above the product, which can be optionally operated for better air distribution inside the unit. The belt is continuously cleaned by special scrapers mounted above the belt. The scrapers are mounted at the belts return side at the freezers inlet. The unit is equipped with a pneumatically controlled quick release system for easy cleaning and maintenance as well as belt in-line automatic control system. The Crust Freezer can be used as a stand-alone unit or as an integrated part of a fully automated processing line.
