Dosing screw motor complete SCHAERER Spare Parts 3370072800

A dosing screw motor powers the helical auger that delivers measured quantities of dry ingredients like coffee grounds, milk powder or sugar into the brewing chamber. The motor rotates the screw at a steady speed, advancing each portion with every turn. This mechanism prevents clumping or bridging, ensuring uniform portion sizes and repeatable beverage quality in high-volume coffee service.

The operator fills the hopper with the chosen ingredient, selects the portion size on the parent machine's control panel, and initiates the brew cycle. The motor then runs for the programmed duration, turning the screw until the exact weight or volume is dispensed. Once the cycle completes, the motor stops, releasing the ingredient into the brew group or mixing bowl.

This spare part is built to the original SCHAERER specifications, matching the shaft diameter, mounting pattern and electrical connections. It replaces the dosing screw motor in SCHAERER coffee equipment listed under article 3370072800 in the manufacturer's spare-parts catalogue.
