US Patent:

40688321, Jan 17, 1978

Filed:

Dec 8, 1975

Appl. No.:

5/638291

Inventors:

Philip H. Blaetz - Barrington IL

Assignee:

Kraft, Inc. - Glenview IL

International Classification:

A01J 1100
A23C 100
B01F 700

US Classification:

366280

Abstract:

A dasher is described for whipping fluid food products in a chamber. In this embodiment the dasher includes axially spaced frame members supported in the chamber and at least two cages mounted between the frame members. At least one of the cages is radially displaced from a longitudinal axis of the chamber. At least one of the cages is rotatable with respect to one of the other cages.

Kraft, Inc. - Glenview IL

International Classification:

G01K 102
G01K 1300

US Classification:

374 44

Abstract:

A device is provided which simulates heat transfer into a flexible pouch in which food or like product is cooked and sterilized. The simulator is a block of polymeric material having a thickness approximately that of a food pouch and a thermal diffusivity generally equal to or slightly above that of food product. A thermal sensor is disposed centrally within the block of polymer material and is connected to electrical leads extending externally of the retort to apparatus that records temperature change as a function of time. A plurality of simulators are placed at various regions in the retort, and the uniformity of the heat transfer under certain operating conditions is determined by measuring the heating rates of the several simulators. Operating conditions, such as flow rates or location of introduction of water, steam and air are changed until a sufficiently uniform heat transfer environment is achieved.
