Yeast liquid and yeast residue are the main products of brewery. Saccharomyces cerevisiae is colonized on malt agar medium with milky white, shiny, flat, neat edges, many uses such as edible, medicinal and feed additives. How can yeast liquid be dry to be active? Its special equipment is a steam drum dryer.
Drying of the yeast fermentation broth is indirect drying by steam, and the moisture content of the dry material can be reduced to about 12%, which can be maintained for a long time. A yeast fermentation broth drying equipment has an hourly drying capacity of about 50 to 160 kilograms, and can be custom-made, so there is no upper limit to the capacity.
Several technical elements of yeast liquid drying equipment are mainly reflected in: steam pressure (0.1-0.4Mpa) or heating medium temperature; general drying equipment drying cylinder speed is generally 4 to 10 revolutions per minute, different film thickness (ie material attached) drying efficiency and drying efficiency may vary depending on the thickness of the dryer surface. Different yeast liquid solids content, fluidity and temperature will also affect the yeast drying process. Therefore, the customer needs to provide the necessary yeast liquid data, and then the drying equipment manufacturer custom design to achieve high efficiency and low cost.
The professionally designed yeast liquid drying equipment can preserve the yeast activity well, retain beneficial bacteria, improve feed quality and promote animal digestion.
