Low-Temperature Protection: The Secret to Drying Active Substances in Organic Fertilizer
Beneficial bacteria such as Bacillus subtilis in organic fertilizers experience over 90% inactivation within 30 minutes at temperatures above 65℃. Through three technologies—low-temperature belt drying (inlet air temperature 45-55℃), microwave-assisted dehydration, and vacuum pulse drying—the effective viable bacteria retention rate can be increased to over 85% while reducing the moisture content from 60% to 25%, ensuring the finished product meets the NY 884 bio-organic fertilizer standard.
