Introduction
In order to preserve ice cream quality, fast freezing of products to approximately -18°C is necessary, before end packaging to cartons. Fast freezing in a hardening tunnel limits the growth of ice crystals, therefore conserves optimal ice cream texture. VOJTA Equipment HT tunnels are designed to rapidly freeze flat top cones, family packs, cups, and other products, made by other machines. Loading and unloading can be manual or automatic. HT tunnels are based on tray chain system, placed inside insulated box. Freezing is done by one or more evaporators, cooled by refrigerants: freon, ammonia and CO2. HT tunenls are produced for up to 3 000kg/hour, depending on product type and size.
