Indretning til køling af væsker og spiselige skumprodukter

摘要

The invention relates to an apparatus with a control for deep-freezing edible foams or other fluids to temperatures below -10 DEG C, while simultaneously producing a creamy state. At the same time, since use is made of a special twin-screw system which is temperature-controlled on the outside and on the inside, it is ensured that there is a mechanical energy input which is homogeneous to a great extent at the same time as heat dissipation which is spatially constant to a great extent. The optimum matching of mechanical energy input, homogeneous structural loading, subcritical shearing (minimisation of structural destruction), cooling gradient (taking into account dispersed energy) and freezing process is carried out according to the invention by means of controlling the mechanical and thermal energy balance on the basis of detecting the product consistency as the target variable. The product consistency is determined, for example, by means of on-line viscosity measurement.
