Configurable spiral freezer

A reconfigurable freezer, comprising:

• a housing having an internal space therein, and first and second openings each in communication with said internal space;
• an infeed assembly and an outfeed assembly, the infeed assembly constructed to be removably mounted to the housing at one of at the first and second openings for being in communication with said internal space, and the outfeed assembly constructed to be removably mounted to another of the first and second openings for being in communication with said internal space, wherein the infeed and outfeed assemblies are interchangeable at the first and second openings;
• a conveyor belt transiting the internal space from the infeed assembly to the outfeed assembly;
• a drum disposed at the internal space for supporting movement of the conveyor belt about the drum between the infeed and outfeed assemblies;
• a first compartment and a second compartment disposed at different sides of the housing, each of the first and second compartments in fluid communication with the internal space;
• and
• at least one blower disposed in the first compartment, said second compartment providing a return space for a gas flow to the first compartment.
