Abstract
A method of removing particulate or aggregate 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, recurrently removing the frost deposits by a current of compressed air directed towards and brought to sweep over the cooling-coil batteries. The apparatus for carrying out the method includes 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.
Claims8
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, comprising
- a plurality of compressed-air nozzles and means supporting said nozzles for imparting reciprocating motion to said nozzles longitudinally of the cooling-coil batteries and including a movable carriage which travels along a rail or track mounted adjacent said cooling-coil batteries, and
- means for furnishing to said nozzles compressed air of such pressure and temperature as to blow frost deposits from the cooling-coil batteries without melting such frost.
