FIELD: food industry.
SUBSTANCE: method envisages food products vacuumising simultaneously with their impregnation with an impregnation compound. The impregnation compound is pumped under a pressure through the products being treated by way of circulation by means of a pump, captures oxygen and is repeatedly supplied to the pump inlet after additional vacuumising. The device includes a container (1) with a lid (2) for placement of products being treated, a vacuum chamber (6) connected to the charge vessel (11) by an additional pipe via a valve (10), a pump (3) providing for the impregnation compound circulation, and a heater (5); the listed components are sequentially interconnected to control elements by means of a pipe. Inside the vacuum chamber (6), the pipe outlet is equipped with a perforated plate (7).
EFFECT: food products storage life increase.
