2.2.2 Feed screw
The product is compressed in the hopper by the feed screw (1) and fed to
the thread of the double screws with the aid of the vacuum. Spiral stopper
(2) improves product feed. The scraper (3) attached to the feed screw
completely empties the hopper. The scraper is easy to remove for clea-
ning.

2.2.3 Double screws
The double screws ensure that the product is conveyed gently and evenly
to the outlet. The same volume is conveyed with each rotation of the dou-
ble screws. In this process, the proportion of air in the product for lling is
reduced by the vacuum applied. The double screws feed until completely
empty. The speed of the double screws and thus the quantity of product
portioned can be innitely adjusted.
The product for lling can be portioned either continuously or in individual
portions. If portioning individually, the number of double screw rotations is
a measure of the weight of the individual portion. Individual portions can
be linked in the pauses between individual portions.
