Martin Bauer Group: Spark Extinguishing for Tea Production

How GreCon detects and extinguishes sparks and glowing embers in tea processing - using 120 °C hot water steam to protect sensitive plant areas.

Published 7 April 2026

Wherever combustible, fine materials exist, fires and explosions can occur for different reasons, but generally with devastating consequences. State-of-the art systems that detect and eliminate sparks can effectively avoid damage to property and people as well as cost-intensive production downtime.

Our order books are full, and we cannot allow ourselves to have any production downtime.Konrad Ohlmann | Production Manager Martin Bauer Group

Our solution for Martin Bauer Group

Spark extinguishment for the tea production

Therefore, highly sensitive detectors are required which reliably detect sparks and glowing embers even in case of product adhesion occurring during the production process. Extinguishment is achieved with hot water steam having a temperature of 120 °C which is most suitable as extinguishing agent. The low water quantity reduces the effect on downstream process steps to a minimum, but reliably protects sensitive plant areas, such as filter systems.

Risks of fire and explosion

The processing of tea holds many risks of fire and explosion. Foreign objects and the mechanical processing can create sparks or glowing embers that can cause fires or even dust explosions within transport ducts or downstream plant areas.
