Abstract:
1. A method for compressing and freezing elastomeric forms, comprising: circulating a liquefied gas through a circulation loop, the circulating comprising: compressing an elastomeric form within an interface of the compression chamber; maintaining compression of the elastomeric form for a time period sufficient to freeze the elastomeric form in a compressed state, wherein the circulating is performed during at least a portion of the compressing and maintaining steps; cooling a storage chamber utilizing exhausted liquefied gas vapor from the source of liquefied gas; storing the elastomeric form in the compressed state in the storage chamber; monitoring the temperature of the storage chamber; and controlling flow of the exhausted liquefied gas vapor to the storage chamber to maintain the temperature of the storage chamber in a specified storage temperature range.
