Yeast dryers are professional drying equipment specifically designed for various yeast materials. They are primarily suitable for dehydrating and drying active dry yeast, fresh yeast, brewer's yeast, feed yeast, and yeast waste liquid. They are widely used in food fermentation, beer brewing, bio-feed, and biotechnology industries. Addressing the characteristics of yeast—high heat sensitivity, easy inactivation at high temperatures, easy protein denaturation, and viscous materials that are difficult to dry—yeast dryers employ a low-temperature indirect drying process. Unlike traditional hot air high-temperature drying equipment, this method can quickly remove moisture while fully preserving the yeast's biological activity, nutrients, and fermentation performance, ensuring uniform and stable finished product quality.
This equipment primarily uses steam as a heat source, indirectly conducting heat through a drying cylinder. The material does not directly contact high-temperature flue gas, creating a clean and mild drying environment. Liquid or paste-like yeast material evenly adheres to the surface of the drying cylinder, forming a thin film. As the cylinder rotates at a constant speed, the material gradually evaporates moisture in a constant-temperature, sealed environment. Drying is completed in a single rotation. The material is then automatically scraped out by a scraper, completing the entire process of feeding, film formation, drying, and unloading in one operation. This method boasts a high degree of automation, fast drying speed, and uniform moisture content in the finished product. The equipment supports multi-dimensional adjustment of speed, temperature, and feed rate, adapting to the processing needs of yeast raw materials with different concentrations and moisture contents.
The yeast dryer operates without dust. All parts in contact with materials are made of high-quality stainless steel, which is corrosion-resistant, easy to clean, and residue-free, meeting food-grade hygiene standards. The equipment boasts high thermal efficiency and low heat loss, making it more energy-saving and cost-effective compared to traditional drying equipment. The machine has a compact structure, small footprint, and stable operation, enabling continuous industrial production around the clock, with high throughput and consistent product quality.
In addition to processing finished yeast, this equipment can also be used for the recovery and drying of waste brewer's yeast and yeast residue from fermentation waste liquid, effectively realizing the resource utilization of industrial by-products, reducing waste liquid discharge, and improving resource utilization.
