Circulating Grain Dryer
Product Overview
The circulating grain dryer is a continuous batch drying machine specially designed for grain crops. It dries grains in a repeated cycle, solving the problem that mobile grain dryers cannot dry high-moisture raw grains due to short drying time. This drying equipment is suitable for drying a variety of grains such as rice, wheat, corn, soybeans, and sorghum. The circulating grain dryer is widely used in grain stations, farms, grain depots, planting cooperatives, and grain processing plants, and is an indispensable post-harvest solution in modern grain production.
Main Characteristics
~ Adopting a multi-stage circulation drying process, combined with tempering, effectively reducing thermal stress and preserving grain quality.
~ Equipped with high-efficiency hot air furnace and powerful blower system to ensure rapid and uniform drying while saving energy.
~ A variety of heat sources are available, such as biomass burners, diesel, gas, coal, and electric heating.
~ Integrated PLC control system supports temperature and humidity adjustment, grain circulation management, and fault alarms.
~ Compact structure, small footprint, flexible layout, easy installation and convenient maintenance.
Working Principle
The circulating grain dryer adopts the method of “intermittent feeding, continuous circulation” for efficient grain drying:
Feeding: High-moisture grain is loaded into the internal storage bin of the dryer.
Heating and drying: The hot air provided by the hot air furnace quickly heats the grain in the drying section, causing the moisture on the surface to evaporate.
Tempering (Moisture Equalization): The grain is retained temporarily to allow internal moisture to redistribute evenly, preventing surface cracking.
Re-drying: The grain re-enters the drying section for another round of moisture removal.
This cycle repeats multiple times until the grain reaches the target moisture level, after which it is automatically discharged.
Applications
The tower type circulating grain dryer is widely used in grain purchasing station, agricultural planting cooperatives, rural grain depots, grain processing plant, feed processing plant, large scale farms, modern agricultural parks, etc.
