Fine yeast extract is exceptionally sensitive to moisture. Even brief exposure to humid ambient air during cooling causes lumping, filter clogging, and production stoppages that compromise both output and product quality. DST desiccant dehumidifiers maintain a consistently dry environment throughout the yeast production process — from fermentation and spray drying to cooling, packaging, and storage — regardless of season or outdoor climate.
The critical vulnerability in yeast production occurs when hot, dried yeast extract is cooled. As the extract cools, it attracts moisture from the surrounding air — causing particles to clump together, blocking air filters, and coating equipment surfaces. In summer or in humid climates, this problem becomes severe enough to halt production entirely.
DST dehumidifiers supply dry, conditioned air throughout the production environment, ensuring that the ambient air in contact with cooling extract contains insufficient moisture to cause re-humidification. The result is consistent production conditions year-round, reduced downtime, lower maintenance requirements, and a higher-quality end product — without the need for additional chilling equipment.
See how DST desiccant dehumidification systems are integrated into yeast production facilities — from spray drying towers and cooling areas to packaging rooms and fermentation tank zones. Our solutions maintain stable, low-humidity production conditions that protect product quality and keep lines running throughout the year.
DST supplied spray drying dehumidification for SAF-NEVA, the Russian arm of Lesaffre — one of the world’s leading yeast manufacturers — protecting yeast extract quality during the spray drying and cooling process.
DST installed production area dehumidification for Angel Yeast in Dehong, China — one of the world’s largest yeast producers — maintaining dry conditions throughout the yeast manufacturing process.
DST supplied brewery dehumidification for Carlsberg’s facility in Falkenberg, Sweden, maintaining stable humidity conditions across the production environment.
DST has been supplying humidity control solutions for yeast production and brewery environments since the late 1990s — across spray drying operations, fermentation areas, packaging rooms, and tank storage facilities in Europe, Asia, Africa, and North America. All systems are configured to the required humidity setpoint and production environment of your facility.
