FIELD: technological processes; transportation.
SUBSTANCE: invention relates to the granular product (2) dispenser (1) with housing (3) with at least one granular product (2) receiving opening (4) and outlet (5) configured to be positioned within the granular product (2) container (12). This outlet (5) is configured to be closed by the sealing element (6). Sealing element (6) is located on the previously displaced by the spring (7) metering piston (9), made with possibility of axial displacement in the pneumatic cylinder (8). Pneumatic cylinder (8) is provided with compressed air supply connection (10) so, that the metering piston (9) is configured to move by means of compressed air relative to the spring (7) and the outlet (5) is made with possibility of opening. Spring (7) is made at least two-staged so, that the metering piston (9) stroke can be changed in at least two stages due to thee compressed air pressure changing.
EFFECT: device operation is simplified, there is no need to use electricity.
