Device for the cooling of articles and its use |
| 摘要 |
The device according to the invention for the cooling of articles, comprising at least one channel which can be connected to a first coolant source such that a first stream of a first coolant can flow through the channel, the articles to be cooled being introducible into the stream, is distinguished in that at least one cross-sectional stabilizer for stabilizing the cross section of the at least one channel is formed. The device according to the invention advantageously allows the defined cooling of articles, in particular the freezing of drops of a liquid or pasty material, in particular of liquid or pasty foods. In particular, a deformation, such as warping, of the channels on account of pronounced temperature gradients and/or temperature transients is effectively reduced. Thus, even after cooling-down operations, uniform cooling conditions can be ensured. |

1. A device for the freezing of a pasty or liquid mass of food, comprising:
a dropper receiving the pasty or liquid mass and forming falling drops of the pasty or liquid mass; a corrugated metal sheet each of the corrugations of which extend in a longitudinal direction, the corrugation having a plurality of minima and a plurality of crowns, an upper side of the corrugated metal sheet receiving liquid nitrogen from a liquid nitrogen source that flows in the longitudinal direction along the upper side of the corrugated metal sheet in flow channels formed by one of the minima surrounded by maxima on each side, the dropper being disposed above the corrugated metal sheet to allow the drops to fall into the liquid nitrogen flow on the upper side of the corrugated metal sheet; a planar base component also extending in a longitudinal direction that is soldered or welded at transverse side ends to the corrugated metal sheet to form at least one liquid and gaseous nitrogen leak-tight cooling conduit receiving the liquid nitrogen from the liquid nitrogen source; and means for preventing flexion of the corrugated metal sheet in the longitudinal direction comprising a plurality of bar-shaped cross-sectional stabilizers each one of which is fixed to the base component and also fixed to a respective one of the minima of the corrugated metal sheet in a punctiform manner.
