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
cleaning.
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
double screws, air being withdrawn from the product by the vacuum
system. The double screws feed until completely empty. The speed of the
double screws and thus the quantity of product portioned can be infinitely
adjusted.
The product for filling 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.
