Abstract
Pressure sensing transducer 140 monitors pressure transients in the liquid in accelerator tube 110 of a hydraulic cutting system induced by food product impinging upon, being cut by, and passing through cutter blade assembly 80. The occurrence of above-normal pressure transients indicates the presence of a system blockage caused by failure of food product to pass cleanly through the cutter blade assembly, and is used as a control signal to activate stepping motor 170 to rotate cylinder assembly 12. Cylinder assembly 12 contains a plurality of barrel assemblies holding cutter blade assemblies 80 and is rotated to index clean barrel assemblies into the hydraulic cutter system pressurized fluid flow path, either upon the detection of a system blockage, or in a timed automatic replacement sequence.
