초록 ▼

The invention includes a tunnel-conveyor section designed to process large-scale quantities of such materials as automobile tires for frangiation and embrittlement to low- or cryogenic-temperature levels for separation of fibrous and metal portions and subsequent granulation into fine-mesh particles. The system is also designed to subject food products to low- or cryogenic-temperature levels prior to for long-term storage and shipping as well. The system can also be used for freeze drying at very low temperatures (-380°F. and lower) when nonconveyor procedures are used. The unit can be adapted as a horizontal-cylinder as well as a spiral or circular system for large-scale conveyor operations. Smaller systems can also be fabricated for laboratory or smaller-scale procedures.

대표청구항 ▼

An apparatus for cooling or freezing materials to low- and cryogenic-temperature levels comprising: a) an external source of low-temperature or cryogenic-liquid coolant; b) a closed insulated container; c) one or more chambers within said container, each said chamber having a flat bottom, sides and a top within said container and at least one opening for entry and exit into said chamber, each said chamber being situated within said container so as to form coolant containment spaces around said chamber; d) means for introducing said liquid coolant into said container to fill said coolant containment spaces to predetermined levels around said chambers; e) a means of entry through said opening into each said chamber for positioning said materials into close proximity with said flat bottom of said chamber so as to allow gradient bottom-to-top heat absorption from said materials by said coolant through said flat bottom of said chamber for primary cooling of said materials to low-temperature or cryogenic-temperature levels; and f) a means for directing coolant vapors collected in said coolant containment spaces into each said chamber over said materials to provide additional cooling of said materials or to material cooling areas external to each said chamber.
