Abstract

The invention concerns a process and an apparatus for the continuous heat treatment of foodstuffs. Unlike in known cooking or boiling installations with a substantially homogeneous temperature control of the heat carrier in the form of water, a multizone installation comprising preheating, boiling and recooling zones is suggested, through which the foodstuffs to be treated are passed successively. The heat carrier is conducted through the recooling zone in a direction counter to the conveying direction and then, bypassing the boiling zone, is supplied to the preheating zone leading to a temperature rise in the latter due to the thermal energy passing to the heat carrier during the recooling process. The energy demand is covered by the heat supplied to the boiling zone, which also operates in the countercurrent principle with the aid of circulating means.

Dependent claims

Apparatus for continuously processing foodstuffs for the purpose of at least one of boiling and dewatering them under atmospheric pressure by contact with a heat carrier in the form of water, said apparatus comprising

an installation having a preheating zone, a boiling zone and a recooling zone, each of which zones is arranged separately and has an inlet region and an outlet region, and in which zones troughs are installed, each being provided with chambers and traversed by means for conveying said foodstuffs,
heat exchange means for transferring the thermal energy to be supplied to said heat carrier,
means for supplying and removing said heat carrier and
means for conveying said heat carrier within said installation,
wherein
said means for supplying said heat carrier are provided in said outlet region of said recooling zone and said means for removing said heat carrier are provided in said inlet region of said preheating zone,
said inlet region of said recooling zone is connected with said outlet region of said preheating zone by pipe conduct means, in which is intermediately arranged a feed pump as means for supplying said heat carrier and controlled in accordance with the supply quantity of said heat carrier into said recooling zone, and
said heat exchange means are installed in said boiling zone.
