High drying quality and energy saving grain dryer
Application:
Grain dryer is the drying equipment which is designed for grain crops. It is mainly used for rice, corn, wheat, sorghum, soybean, rapeseed and other granular food and economic crop though low temperature air to reach desiccation. After drying, the crops have many advantages such as high quality, low crackle ratio, low temperature, large output and so on.
Structure characteristics:
Grain dryer is mainly composed of feeding device, bucket conveyor, drying box, precipitator, efficient hot blast stove, draught fan, online thermometer, rapid water meter, electrical control system and other systems. Among them, the hot blast stove can be used separately drying chili, cowpea, honeysuckle, vegetables and other sticks or block materials. In a word: multi-usage.
Performance characteristics:
Grain dryer can guarantee the quality of crops by using circulation drying method. Circulation drying method refers to work circularly among down-flow, counter flow and mixed flow which can effectively control drying chamber’s temperature to make all the crops have enough contact with airflow. In the process of drying, there have less crushed phenomenon and very low crackle ratio so that it won’t change crops’ natural color and nutrition. What’s more, the drying speed is very fast, dried crops can be sent out after rapid cooling. With the improvement of grain dryer, it has functions of eliminating dust, edulcoration and deinsectization to make the corps easier to save.
Working principle:
Grain dryer adopts rotary heating device, it can output enough hot air in a short time and kill eggs though high temperature. It also adopts digitization control and instrumentation to control drying box’s temperature to avoid appearing discoloring and metamorphic phenomenon. Drying cabinet is made of metal aluminum plate and silica gel cotton insulation layer to reduce energy consumption effectively. Cyclotron system can reach the purpose of air circulation, humidification and heating in the drying box.
