Bean hopper lid SCHAERER Spare Parts 3323962100

A bean hopper lid seals the container that holds coffee beans at the top of a commercial espresso machine. The hopper itself is a clear or opaque vessel where whole beans are stored before grinding. Without a lid, beans are exposed to air, light and moisture, which accelerate staling and loss of aroma. The lid also prevents foreign objects from entering the hopper and blocks the escape of beans during transport or when the machine is tilted.

The lid is placed directly onto the hopper rim and is held in position by friction or a slight interference fit. Some models incorporate a small gasket to improve the seal. A central opening, often covered by a flip-up flap, allows beans to be added without removing the lid entirely. The flap may also serve as a measuring guide, indicating when the hopper is full.

To use, the operator lifts the flap, pours beans into the hopper until the desired level is reached, then closes the flap. The lid remains in place while the machine grinds and brews, ensuring the beans stay fresh and uncontaminated. When the hopper needs cleaning, the lid is lifted off by hand and set aside.

Construction is typically injection-moulded plastic, chosen for its light weight, durability and resistance to coffee oils. The material is food-safe and withstands the temperature variations inside a working coffee station.

This lid is a direct replacement for SCHAERER coffee machines and fits the bean hoppers specified in the manufacturer's parts catalogue. It is listed under the beverage preparation section of the professional catering equipment range.
