Abstract
Abstract In an installation for the continuous heat treatment of foodstuffs, it is suggested to subdivide the installation through the use of a series of separate containers for receiving an aqueous heat carrier, the sections formed by these separate containers being traversed successively by a conveyor for the material to be processed. These containers can be connected with each other in a variable manner with regard to the fluid conduction. The thus variable through-flow system makes it possible to take account in an optimum manner of the product-related nutrition-physiological and sensory requirements, while simultaneously the operating costs of the process can be minimized.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
157 words
An installation for the continuous heat treatment of foodstuff material under atmospheric pressure for at least one of finishing and dewatering said material through contact with a liquid heat carrier, said installation comprising: a housing having inlet and outlet means for said material to be treated and including a series of treatment zones; endless conveyor means driven to traverse said treatment zones successively in a conveying direction for conveying said material to be treated through said treatment zones; means for supplying and removing said heat carrier and for conveying the same within said installation; heat exchange means for controlling an enthalpy of said heat carrier; a series of containers arranged separately from each other and to receive said heat carrier, respectively; and said means for supplying and removing said heat carrier including means for permitting said supplying and removing to be controlled independently between said containers for a variable exchange of said heat carrier within said installation.
Claim 2
Dependent Claim
157 words
An installation for the continuous heat treatment of foodstuff material under atmospheric pressure for at least one of finishing and dewatering said material through contact with a liquid heat carrier, said installation comprising: a housing having inlet and outlet means for said material to be treated and including a series of treatment zones; endless conveyor means driven to traverse said treatment zones successively in a conveying direction for conveying said material to be treated through said treatment zones; means for supplying and removing said heat carrier and for conveying the same within said installation; heat exchange means for controlling an enthalpy of said heat carrier; a series of containers arranged separately from each other and to receive said heat carrier, respectively; and said means for supplying and removing said heat carrier including means for permitting said supplying and removing to be controlled independently between said containers for a variable exchange of said heat carrier within said installation.
