At first sight the BRZ sample roaster (Battery Sample Roaster with Cyclone) doesn’t have any resemblance with its bigger counterparts, the classic drum roasters of KIRSCH + MAUSSER. At second sight though, you can make out the traditional drum, which in this case is swivel-mounted with a handle attached to the back for emptying of the drum into the cooling sieve positioned at the front. When looking to the roasting principle, further similarities come up as it is also based on the strict separation of movement and heat supply: Small paddles in a rotating drum move the coffee beans while heat is supplied by a gas-powered burner (or by an electrical heating unit) mounted under the drum and transferred directly to the beans through contact with the drum's hot metal surface. For separation of chaff from the roasting exhaust air, the BRZ sample roaster is additionally equipped with a cyclone.
The smaller version, the sample roaster PRE/PRG (Sample Roaster electrically or gas-driven), is a single-drum roasting machine with cooling fan. Due to its integrated chaff separation, the sample roaster PRE/PRG requires particularly little space and is also convenient and easy to operate.
The BRZ sample roaster stands out for its sturdiness and durability and is particularly suitable for grading green bean quality, thus providing valuable support in quality control as well as production development processes. As two, four or six-drum version with a batch capacity of 100 g per drum, the BRZ sample roaster has become an indispensable aid on farms and plantations as well as in coffee roasting plants.
The sample roasters belonging to the KIRSCH + MAUSSER product portfolio are specifically tailored to the corresponding applications and offer many benefits:
For convenient handling of the roasting process, KIRSCH + MAUSSER offers specially designed sample spoons and vessels for filling the green beans into the roasting drum. Furthermore, a wide range of customization options for the wooden base plate and the machine body make the sample roasters a unique addition to any roastery. More individual design options are possible.
