OPEN LOOP HEAT PUMP SYSTEM
One of the main advantages of steam drying is the possibility to recover the excess product steam through Mechanical Vapour Recompression (MVR) and use this heat as thermal energy source for the process steam. Open loop heat pumps are often called Mechanical Vapour Recompression. If connected to an industrial process, in our case superheated steam drying, the dryer functions as the evaporator of the heat pump. The water in the product is removed in the form of excess steam and normally wasted, because it is too cold to be utilized further.
The open loop heat pump is compressing this excess steam to a higher pressure level where it can be condensed at higher temperatures hereby re-heating the process steam of the dryer.
