Patent number: 5277109Abstract: This invention is particularly useful in food processing for separating crumbs and particles of breading material which have become suspended in frying oil, so that the oil may be reused. Separation is done in a unique cylinder having a hollow piston, whose forward end has a screen and whose aft face is imperforate. The cylinder has an openable door at its forward end. Near its end door the cylinder has a liquid inlet and a liquid outlet spaced somewhat aft therefrom. When the piston is in its retracted position its screen end is positioned axially between the inlet and outlet, so that the liquid may pass through the screen. Air pressure in the portion of the cylinder aft of the piston acts against its imperforate face to drive it forward. The screen end of the piston filters and drives the liquid back to the outlet, solids are compacted against the door.Type: GrantFiled: September 3, 1992Date of Patent: January 11, 1994Assignee: Custom Metalcraft, Inc.Inventor: Charles A.

Patent number: 4757758Abstract: An extrusion-type trash compactor in which the trash receiving chamber is inclined downwardly towards an outlet opening at an angle of about forty-five degrees, and the outlet opening connects with the inlet of a compacting chamber that is disposed horizontally, whereby the overall length of the compactor is reduced to adapt the compactor for use in smaller trash rooms. The angle of the ram also functions to reduce blockages in the hopper by working the bottom of the accumulated pile of trash as it's moved relative thereto - which reduces the possibility of trash backing up into the chute leading into the hopper and thus reduces damage that may be caused by fire. The compacting chamber is also pivoted to the outlet opening of the receiving chamber to permit it to be opened for the purpose of clearing jams in the compacting chamber.Type: GrantFiled: October 7, 1987Date of Patent: July 19, 1988Assignee: Arrow Steel Inc.Inventor: Frank Tondo
