HISTORY of VINCENT SHREDDERS
Vincent started making shredders in the 1930's, to improve the capacity of the dryers we operated (making cattle feed out of orange peel). Today we still offer shredders, but generally for the limited applications with which we are familiar: citrus waste, pineapple juice, and produce waste.
Vincent made shredders with vertical shafts, but these had severe maintenance problems. The main difficulty related to the lower bearing being in liquid from the shredded material.
In 1968 the Rietz company merged with Vincent. They took our screw press designs, and we dropped our vertical shredder in place of their Rietz RD-18, which is a much better vertical shaft shredder.
That deal soon fell apart, and Vincent resumed making their own shredders (or hammer mills). These shredders had a horizontal shaft with a screen surrounding the lower 180 degrees below the rotor.
These shredders were designated Series VS, for Vincent Shredder. We have two versions of these shredders: thin blades and thick blades. The thin blades were used to slice lime and lemon peel in pectin peel washing operations. The thin blades were susceptible to damage from tramp metal. Thick blades hold up better to tramp material and are used in shredding orange peel to make cattle feed.
A few years ago we came out with the Series VCS shredders: Vincent Comb Shredder. The blades of the rotor fit between fixed teeth. These fixed teeth form a grill or comb. They run from one side of the housing to the other. As the blades of the rotor spin, there is a scissors action, slicing the material. (There is no screen.) Most of these operate without using the comb, just doing a rough pre-breaking.
Vincent offers shredders primarily as an accessory machine to go with our screw presses. We keep a few in the rental fleet.
