Title: Horizontal wine press - has slotted press cage shell which rests only against press end plates
Inventor: BREDEBUSCH HEINRICH
IPC: B30B9/26
Filed: 1974-04-17
Abstract: The press, has a rotating cylindrical press cage through which passes a central support spindle. The pressed material is pressed between two ends of the press of which at least one travels axially. This press cage is relatively simple and cheap design because the end support rings are eliminated. The press cylindrical cage, is made from stainless steel or from timber. The torsional stiffness of the cage is increased by timber blocks in the slots between longitudinal timber strips. The ends of the press spindle are mounted on supports. The spindle is fixed and not able to rotate. On one end of the spindle is fitted a freely rotating gearwheel whose rim under the teeth is connected to the cage end. This wheel is driven by the pinion and motor. The rotating cage imparts rotating movements to the other cage and which is connected by its hub to the screw thread of the wpindle. This end moves axially towards the fixed end and hence presses the content of the cage whose juice is extracted and flows out through the slots.
