Case study: Regenerative thermal oxidizers for coffee roasting

Epcon has extensive experience in designing and building Regenerative Thermal Oxidizers (RTO's) for the Coffee Roasting Industry.

The Problem

A leader in the Coffee Industry needed equipment to control odor and eliminate VOC's from Coffee Roasting. The company went out seeking the technical solutions and went to several manufacturers to locate the best possible technology. In the past they had used a Catalytic Oxidizer which easily became clogged with particulate matter and required the catalyst be changed frequnetly.

The Process

The Coffee Roaster generates exhaust with high particulate matter enriched with VOC's. Epcon has built several systems for Coffee companies for similar applications to control VOC's and odor.

The Solution

Epcon analyzed the process and designed a Regenerative Thermal Oxidizer which does not interrupt the roasting process and quality of the roasting. Epcon's system treats the roaster exhaust in an RTO to remove 99% of VOCs. Epcon has selected the regenerative thermal oxidizer because it can reduce fuel consumption without having an issue with particulate matter present in the roaster exhaust.

The Benefits

Epcon was able to achieve the same fuel consumption as the Catalytic Oxidizer with the Regenerative Thermal Oxidizer and also handle the particulate matter in the exhaust without having an issue with clogging. We were also able to remove the odor and the VOC’s by 99%+. On an ongoing basis, Epcon provides Preventive Maintenance Service to the customer and the system has been operating very successfully.
