METHOD OF LOW-TEMPERATURE MOULDING SOLID BIODEGRADABLE OBJECTS Russian patent published in 2009 - IPC B29C71/02 B29D22/00 B29D23/00 B32B1/08 

FIELD: engineering processes.

SUBSTANCE: group of inventions relates to a method of making solid biodegradable objects from wheat gluten and a solid object made using this method. Hydrated wheat gluten is in form of sticky, elastic dough. The sticky, elastic dough contains at least 8 wt % wheat gluten, where wheat gluten contains a protein primary structure. The sticky, elastic dough is moulded, obtaining a shaped object and the latter is put into a medium where conditions allow for removal of excess water from the shaped object without changing the protein primary structure of the wheat gluten. A solid biodegradable object is obtained as a result, where the said object contains at least 8 wt % gluten. The shaped object is put into a medium with temperature approximately lower than 60°C. Moulding the object involves the following operations: flattening the sticky, elastic dough, putting the sticky, elastic dough into a mould which has male and female parts, and compressing the flattened sticky, elastic dough in the mould, thereby obtaining a shaped object. The solid biodegradable object is made in accordance with methods given in subclaim 1 or 5.

EFFECT: provision for a low-temperature moulding method, which involves drying and not steaming wheat gluten, so that the protein primary structure of wheat gluten basically remains the same.
