Title:
WATER PRESSURE-TYPE FISH SCALING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/007468
Kind Code:
A1
Abstract:
A fish can be efficiently scaled with reduced electric power consumption and reduced water consumption without requiring an increase in the capacity of a high-pressure pump and without requiring an additional pump.
Discharge nozzles (31, 33) are mounted to pivoting portions of pivoting arms (21, 25) and are configured so as to move in circular arc paths. As a result, a single discharge nozzle discharges high-pressure water over a wide range in comparison with the case in which the discharge nozzles (31, 33) are disposed at fixed positions and do not move.
