Abstract:
Apparatus for treating material comprising a container including a plurality of enclosed separate chambers for receiving bodies of material and in which a relatively small clearance will be provided by adjacent surfaces of the chambers and the material therein; the chambers comprising a portion of a heat-exchanger and including means for supplying either heating or cooling fluid in controlled quantities and at a controlled temperature within the container along the chambers, and including means for circulating a treatment liquid in a conduit system to effect circulation and recirculation of the treating liquid through the individual chambers to attain uniformity of treatment and minimizing apparatus space while affording an effective material treatment in a minimum amount of time through accurate and empirical temperature control.
