Abstract: A method and facility for the treatment of brine in salt baths for salting cheese are described. First fractions of dissolved salt are carried along in a cleaned brine permeate and second fractions of dissolved salt are carried along in a contaminated brine retentate. A first quantitative ratio between brine permeate and brine retentate is adjusted in such a manner that the quantity of brine retentate corresponds at least to the quantity of whey and constituents that pass into the brine in the salt bath during the dwell time. The cleaned brine permeate and the cleaned brine are merged in a controlled manner in a second quantitative ratio, by means of which the mixture of both components is concentrated to a salt concentration that corresponds at least to a required salt bath concentration.

Abstract: The invention relates to a drying system (1) comprising a drying plant (2) and a heat pump assembly (3) comprising one or more heat pumps operating with a primary fluid and being connected to at least two heat sources and at least one heat sink by means of a number of heat exchangers in a fluid network, in which a secondary fluid circulates. The heat sources may comprise dew point dehumidification in at least one heat exchanger (41) of process gas entering the drying plant; and recovery in another heat exchanger (42) of latent and/or sensible heat from exhaust gas leaving the drying plant. The heat sink may comprise pre-heating in a heat exchanger (51) of process gas used within the plant. Further, a method of integrating a heat pump assembly into a drying system is devised. By the invention, it is possible to increase the capacity of the drying plant while reducing the specific energy demand.
