ABSTRACT:
The present invention describes a method and apparatus in which solid gelatin chunks are liquefied, tempered, and debubbled in a single operation. The debubbling step is accomplished by evacuating and sealing off the loaded solid reservoir and heat exchanger before initiating the liquefying step. After the vacuum is applied, the gelled chunks are pressed into the heat exchanger, where heat is applied to the gelled chunks of photographic material. This liquefies the gelled chunks of photographic material. When the liquefied product gives a positive pressure at the heat exchanger outlet, the liquefied product is allowed to flow from the heat exchanger. Liquefying and tempering are performed as the solid chunks are pushed through the heat exchanger by the reservoir piston.
