FORMER-EXTRUDER

The MFE Series forming-extruders have been designed for two purposes:
1) processing potato formulas in pellet technology;
2) forming of gelatinized dough coming for the HTE cooker extruder in cereal die cut pellets technology.

The machine is equipped with vacuum in mixing vessel, barrel and head in order to avoid blistering e ect in potato based products. Main components of the unit are:

• our dosing unit consisting of stainless steel hopper complete with rotating paddle and variable speed dosing screw;

• liquid dosing unit consisting of thermostatic mixer, expansion tank, and variable speed pump;

• additional dosing group for cooking oil consisting of a storage unit complete with level probe;

• high capacity stainless steel mixer tank, suitably shaped to reduce stagnation points, complete with air-tight cover;

• stainless steel dosing screw, driven by a variable speed motor that grants constant product dosing to the compression screw;

• stainless steel dosing screw cylinder;

• high tensile induction-hardened stainless steel compression screw;

• compression screw rotating group with r.p.m. reduction system by means of direct reduction gear, driven by a D.C. variable speed motor;

• carbon steel extrusion cylinder, with internal ri es of particular design;

• water circuits for the conditioning of the extrusion temperature, with autonomous circulating pump and automatic temperature control;

• high resistance steel extrusion head;

• a conditioning circuit provided with automatic control of the head temperature by means of a separate circulating pump;

• vacuum unit.
