Abstract
The present invention is for a worm press for extraction of plant and fruit juices, such as orange juice and grape juice. It is important that the pressing takes place at high pressure but that only small amounts of heat are developped. A worm press according to the invention has a housing with an inner circular cylindrical volume, wherein there is a worm screw. The housing has openings as required for the supply of plant material and feed in out of the remains after the extraction. The worm is correspondingly designed with a feed in section and an extraction section. Essential for the invention is the design of the worm threads in the extraction section and the adaption of the worm to the housing in this part thereof. The diameter of the central core (5) of the worm is essentially smaller in the feed in section than in the extraction section. Furthermore, the core diameter and the pitch of thread in the feed in section are preferably constant and the worm here works like a simple feed screw. In the extraction section the diameter of the core as well as the pitch of the worm thread (4) vary. Seen from the feed in section the diameter of the core increases and the pitch of the thread decreases. Furthermore, the core is so designed that its outer surface between the threads always is parallel with the axis of the worm and thus also with the inner cylindrical surface of the housing.
