High performance extruder – DV MODEL

The DV and DFV model cookie depositors from GEA Comas offer high capacity production. The units effortlessly and efficiently handle a variety of mixes for a wide range of products, including smooth mix and wire cut biscuits from fluid, whipped or stiff dough, and mixes that contain solid particles such as chocolate or nuts.

The DV and DFV depositors are designed to be versatile and easily integrated with existing process lines. The units are carried on a specially designed frame that can be cantilevered over the GEA Imaforni tunnel oven. This allows smooth mixes, for example, to be deposited directly onto the oven band. The vertical and horizontal movement depositing heads comprise a pair of motorized rollers that feed the dough mix to the volumetric pumps underneath, and to the individual lobe pump system (ILPS) – one for every outlet. The technology ensures highly accurate deposition across the whole working width.

The depositor feed rollers and lobe pumps are driven by servo-motors for maximum control over the depositing process. Two pairs of independent servo-motors also drive the vertical and horizontal movements of the depositing head. This major reduction in the use of mechanical components has both significantly improved performance and facilitated a design that allows quicker installation over the GEA Imaforni tunnel oven.
