FIELD: food industry.
SUBSTANCE: method includes a stage of pumping out, at which reduced pressure is created in a deformable chamber, a stage of filling, at which a tank is filled with a product, supplying a device containing the tank that is connected to the deformable chamber and equipped with a hole for filling, a closing stage, at which the hole for filling is closed. An inner part of the deformable chamber is at least partially limited with a movable wall, the displacement of which causes a change in volume of the deformable chamber, and is separated from the tank with at least a supply valve, and/or is separated from a device output with at least a delivery valve. Stages of pumping out, filling and supplying are performed in such a way that, in an “intermediate” state of the device, the tank is filled with the product, and the inner part of the deformable chamber is under intermediate pressure that is lower than initial pressure.
EFFECT: invention provides for the high efficiency during use.
