One or more spaced fender elements are located around the helical conveyor (11) to prevent articles from falling off the conveyor.

An orificed helical conveyor having gaps in the perimeter of the conveyor alternating with protrusions along the perimeter of the conveyor agitates the cooling molasses.

A helical conveyor for loading and unloading unit packages (23) is composed of several superposed coils (6, 10).

An orificed helical conveyor having a plurality of protrusions from the outer perimeter agitates the cooking molasses.

In a continuous screw conveyor or auger, the rotatable screw member (12) comprises a helical radial blade (28) (known as 'flighting') which is preferably carried on a central driving shaft (26).

More particularly, the invention contains an auger (4) with specially modified variably pitched paddles (5A) which agitates a stream of waste.

One (20) of the conveyors is fixed while the other (40) is arranged in a cage (30) rotatingly movable about the vertical axis of the helical conveyor.

An improved self-stacking spiral conveyor belt (10) that includes a plurality of interconnected links (15) each including two side plates (40, 60) connected together with two transverse rods (20. 30).

The invention concerns a helical conveyer with a cylindrical housing (1) which comprises a cylinder casing, a lower inlet opening (3) and an upper outlet opening (4).

The first method consists of exposing the green malt to a short heat shock, preferably by applying water vapor via a spiral conveyor (1).
