LF Dosing Spring for Professional Coffee Grinders

A dosing spring controls the flow of ground coffee from the grinding chamber into the dosing chamber of a professional grinder-dispenser. When the barista pulls the dosing lever, the spring compresses, allowing the correct portion of coffee to drop into the portafilter. The spring's tension determines how quickly the chamber refills and how consistent each dose is, ensuring the same amount of coffee is dispensed every time without manual adjustment.

To use the spring, it is fitted inside the dosing chamber of the grinder-dispenser. Once installed, the operator loads whole beans into the hopper, selects the grind setting, and starts the motor. As the grinder produces grounds, the spring regulates their release into the dosing chamber. When the lever is pulled, the spring compresses, releasing a measured dose into the portafilter. The barista then tamps and locks the portafilter into the espresso machine.

The dosing spring is constructed as a coiled metal component, designed to withstand repeated compression cycles in a high-volume coffee environment. Its material and tension are matched to the specific mechanics of the grinder models it fits, ensuring reliable operation without premature wear.
