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.
Claims10
A method of recurrently removing frost deposits from cooling-coil batteries or the like in a freezing plant during operation of such plant while maintaining the frost so removed in its aggregated form, comprising the steps of
- recurrently directing currents of compressed air of such temperature as to not melt the frost deposits and of such pressure as to thereby blow frost deposits off and away from the cooling-coil batteries so that the state of the frost being removed is maintained, said currents of compressed air being directed in a sweeping fashion toward and over the cooling-coil batteries of the plant while maintaining the cooling operation of the cooling-coil batteries.
Apparatus for recurrently removing frost deposits from cooling-coil batteries or the like in a freezing plant during operation, while the state of aggregation of the removed frost deposit is maintained, wherein said apparatus includes at least one compressed-air nozzle and means supporting said nozzle for imparting reciprocating motion to said nozzle longitudinally of the cooling-coil batteries and simultaneously imparting reciprocating motion to said nozzle in a direction generally perpendicular to the longitudinal direction so that in operation of said apparatus said nozzle is recurrently directed towards and brought to sweep over said cooling-coil batteries in order to blow away the frost deposit from the cooling-coil batteries by means of a current of compressed air, and means for furnishing compressed air of such pressure and temperature as to blow frost deposits from the cooling-coil batteries without melting such frost.
