Mixed-flow grain dryer
- Commodity name： Mixed-flow grain dryer
- 产品描述
-
Product Features
- The drying section uses multiple stainless steel angular pipe ducts to ensure even heat exchange between the hot air entering the dryer and the grains, maximizing space utilization, increasing the amount of grain dried in the same time period, improving drying efficiency, and truly achieving the concept of low-temperature drying.
- The exhaust fan is equipped with a frequency converter, which controls the output air volume and pressure of the fan by adjusting the frequency of the fan power supply. This allows for drying grains of different bulk densities and particle sizes, achieving optimal drying conditions.
