Abstract
A method for producing formed blanks wherein the components are premixed in a first stage and metered. Heat and moisture are added to the mixture in a controlled manner and the mixture is then formed into pellets. The pellets are cooled with air, comminuted and further processed into formed blanks after storage for an arbitrary length of time. The method of this invention leads to more homogeneous and improved results and is extremely inexpensive.
Claims12
In a method for producing formed blanks from component mixtures which comprise raw vegetable materials with a starch component and which are put into final form by thermoplastic or duroplastic deformation in an extrusion molding machine, the improvement comprising the steps of:
- prior to final shaping, passing the premixed component mixture through a pellet mill with a feed device and a mixing device while adding moisture and providing heat, allowing only partial agglutination of the starch, and cooling and temporarily storing formed pellets for an arbitrary length of time.
