Design and operation:

Offal originating in the technological process is characterised by various physical properties and has different destinations at further processing stages. For example it can be used as fodder substrate. Offal is divided into three types: feet, heads and intestines. This division determines the necessity of using three paths. As shown in the figure below, at the beginning of each path there is a charging hopper (6). Offal is transported in a closed conduit (acid-resistant, stainless piping) to the separating tank (3). Mass collected in the tanks is removed at appropriate time by opening the bottom flap. Offal falls from the tanks to a container (7). Transport in each path takes place in an alternating manner in automatic cycle. The executive system consists of pneumatic cylinders of very high durability and reliability. Automatic control is performed by a special clock unit (5), equipped with time adjustment system. Offal transport is based on the principle of negative pressure, which is one of its major advantages. Easy deployment and control of each path is another important benefit.
