Hardening cabinets, sometimes called blast freezers, are made to remove heat quickly! For ice cream that means stabilizing ice crystals in your freshly made product at the smallest size possible. For gelato, it's making that thin crust on top that protects your product while it's in the case. Our hardening cabinets do the job in three ways that are significantly different than a regular freezer or dipping cabinet.
First, the compressors are heavy duty and designed to remove large amounts of heat quickly where a dipping cabinet is made to maintain a moderately low temperature for serving your product. Compare a hardening cabinet compressor/evaporator system to a typical dipping cabinet system and the difference is obvious--hardening cabinets have a large compressor and forced air radiator; dipping cabinets have a small compressor and thin wire evaporator.
The second key difference is that hardening cabinets stir the air inside breaking up the relatively warm air layer around products that haven't reached the ambient air temperature of the cabinet. Air layer? Take a look at your hood on a warm day and you'll see the "mirage" near the surface. This layer insulates the hood and keeps it much hotter than the surrounding air. Stirring the air (as in driving) breaks up the insulating layer allowing the hood to cool to ambient air temperature. Same thing happens with frozen products in a hardening cabinet. Speaking of stirring the air, our cabinets are designed to stop blowing when the door is opened to prevent the cold air from being blown out!
The final difference is the much lower temperature range. At -15F, 90% of the water in ice cream is locked into a stable crystalline form essentially preserving it permanently. Even with minor fluctuations from normal compressor cycling, at -30F to -40F, a hardening cabinet is well below this safe range for keeping product at its best for long periods of time.
