Volumetric Screw Feeder

Volumetric dosing screw

The auger feeder series enables the volumetric dosing of powdery products with fine granulation, which can sometimes present problems of compactness, dust content and variable density, such as cocoa, curry and other "powdery" products.

The various problems associated with processing the products are solved, starting with feeding the product through a hermetically sealed hopper equipped with a level sensor and a motorised agitator. The screw, made from a single solid mass, has an electronically controlled speed by means of a servo motor, which allows the use of acceleration and deceleration ramps that ensure an immediate screw stop, thus guaranteeing optimum dosing accuracy.

The input of the production data, the speed values of the motor and the storage of the different formulas according to the product and format is done through a control panel. For products with different densities, the volumetric screw feeder can be connected to a weight control system equipped with a shrinking device to return the weights of the packages to acceptable tolerances according to the variations in the specific weight of the product during operation.
