With a new generation of shop roasters PROBAT has succeeded in linking state-of-the-art technology with a classic design. The well established PROBATONE drum roasters were enhanced with the knowledge of experienced roastmasters. Professional coffee roasting from the perspective of a specialty coffee roaster was the underlying focus of all innovations.
The new models of the shop roaster family are designed for three different batch sizes: beginning with the Probatone 5 with a five kilo batch, the Probatone 12 with 12 kilos per batch and the Probatone 25 for 25 kilos.

3-5 kg | 12-18 minutes | Gas/electric | |
