ABSTRACT:
This invention relates to a method of removing frost deposits from cooling-coil batteries or the like in a freezing plant during operation, while maintaining the state of aggregation of the removed frost deposit. According to the invention the frost deposit is recurrently removed by a current of compressed air being directed towards and brought to sweep over the cooling-coil batteries.
The invention also concerns an apparatus for carrying out the method, said apparatus including at least one compressed-air nozzle which is adapted to be recurrently directed towards and brought to sweep over said cooling-coil batteries in order to blow away the frost deposit.
