DEVICE AND METHOD FOR PRODUCT PRODUCTION BY WAY OF EXTRUSION Russian patent published in 2010 - IPC A23G4/04 B30B11/22 

FIELD: food industry.

SUBSTANCE: invention is related to food industry and may be used for production of striped confectionary products. The device contains means for coextrusion of at least two different primary products into a common flow so that the primary products are combined to form a coextruded flow of the product containing levelled layers of the primary products. The device also contains an extruder head for delivery of a layered coextruded flow of the product. The extruder head contains at least one body element constituting a channel and an essentially helical blade which is rigidly fixed in the said channel for its division into two essentially helical ducts. The blade contains a bit which is positioned so that the layered coextruded flow of the product is divided into two separate coextruded product subflows. The extruder head is designed so that to enable subsequent rejoinder of the subflows into one rejoined flow of the product containing a greater number of levelled layers of the primary products. An appropriate method is also proposed.

EFFECT: invention allows to combine two or more different primary products for a striped product formation.
