CRG/E 100-2 Drums

Designed to last and perform its function efficiently, The CRG/E-100 roasters incorporate the same manufacturing concepts and quality standards with which JOPER builds industrial and shop roasters.

The CRG/E 100-2 sample roaster with 2 drums can run on gas or electricity and it is possible to roast a small batch of 100 grs of green beans, also check and verify the quality of the roasted coffee and use it as a pattern for large scale roasting.

Stable, easy to operate, low maintenance, equipped with digital and temperature control and a thermocouple in the roaster cylinder to measure the temperature of the bean mass itself, the result is highest efficiency in sample roasting.

Without a doubt, JOPER’s CRG/CRE 100 roasters have become the most demanded sample roaster for small, medium as well as large companies, cooperatives, associations of producers, exporters/importers, which made Joper their new suppliers for new projects, as well as for substituting old sample roasters.
