The BRZ sample roaster is the smallest of the PROBAT drum roasters. However, the traditional roasting drum of the Battery Sample Roaster with Cyclone (BRZ) is swivel-mounted with a handle attached to the back for emptying into the cooling sieve positioned at the front.

The BRZ is equipped either with a gas-powered burner or an electrical heating unit, both mounted under the drum. For separation of chaff from the roasting exhaust air, the sample roaster is additionally fitted with a cyclone.

The BRZ is particularly suitable for grading green bean quality, thus providing valuable support in quality control and production development processes. As two, four or six-drum version with a batch capacity of 100 g per drum, it is an indispensable aid on farms, plantations, and in coffee roasting plants.

The sample roaster PRE/PRG (Sample Roaster Electrically or Gas-driven) is the particularly space-saving single-drum variant with an integrated chaff separation and a cooling fan.

With the optional digital package, the sample roasters can be equipped with a digital temperature display and a USB connection. This ensures the recording of temperature values and easy transmission to an external control system such as Cropster or Artisan. The modernized BRZ presents itself in classic black on an oak wood plate. Of course, there are various customization options.
