FIELD: technological processes.
SUBSTANCE: method and device for manufacturing of moulded parts from the base material, namely the pulp, proteins, polylactides or amylum or mixtures from these substances, which is mixed with a solvent to form the moulding solution, and then this solvent at least partially is to be removed from the mouling solution and the mouling solution is fed into the moulding device. According to the invention, the mouling solution is fed into a vertical cylindrical thin-layer evaporator and in a horizontal cylindrical thick-layer dissolver. The moulding solution is diluted in a thick-layer dissolver or at the subsequent unloading from it upto the viscosity required for moulding, achieving the original consistency. At that, the thin-layer evaporator and/or thick-layer dissolver is directly connected to each other through their product chamber.
EFFECT: improved method.
