FIELD: food industry.
SUBSTANCE: invention relates to food products treatment, in particular, to a method for production of puffed grains. The grains puffing method involves operations as follows: loading grain material into the chamber, the chamber pressurisation, the grain material treatment in the chamber, discharging the grain material into the receptacle bin. A preliminarily heated gasiform heat carrier is supplied under pressure into the chamber; after expiry of some time the chamber is immediately depressurised. The grains treated under overpressure are placed into the receptacle bin; the duration of treatment with the gasiform heat carrier is 3-300 sec, the gasiform heat carrier pressure is 0.3-3 MPa, the gasiform heat carrier temperature is 50-400°C.
EFFECT: said invention usage will allow to reduce the costs of puffed grains production, enhance the quality of the product feeding value.
