FIELD: machine building.
SUBSTANCE: invention relates to a device for distribution of loose solid material, for example in grain or powder form, and may be used for distribution of colour material over the surface of the product, for example, for obtaining decorative effect. Device (100) for distribution of loose solid material comprises multiple vibration elements (210) arranged in one plane installed side by side to support material (P) from the bottom. Each of vibration elements is connected to the piezoelectric device (220) configured to convert electric excitation signal in mechanical vibrations that may cause falling material (P) from vibration element (210). Device (100) comprises heaters (240) for heating the vibration elements (210) which are in contact with material (P). Heaters (240) contain at least one heating element configured to emit heat. Heating element stays in contact with vibration elements (210) directly or indirectly via structure (215) from conductive material supporting vibrating elements (210). Method of the device functioning includes a step of heating the plane of vibration elements (210) being in contact with material (P) by means of heating devices (240).
EFFECT: technical result of the invention is possibility of uniform distribution of powder material over the surface, reduced production costs and simplified design.
