Working principle of mobile grain dryer:
The mobile grain dryer adopts a mixed flow drying process, which uses hot air as the heat medium to dry grain.
Its interior is mainly composed of angular ventilation boxes arranged in layers. The outside of the angular box is filled with grain, and the grain flows from top to bottom. Hot air enters through the intake angular box and passes through the grain layer in the up and down direction. The exhaust gas is discharged through the exhaust angular box. Hot air and grain flow both flow in the same direction and in opposite directions, which is called mixed flow.
When the hot air passes through the grain layer, it transfers heat and moisture with the grain: the hot air transfers heat to the grains, causing their temperature to rise. The grains are heated and the water evaporates into the air and is discharged as waste gas.
The dried hot grain flows downward to the slow-cooling section. After passing through the slow-cooling section, the temperature and moisture of the inner and outer layers of the grains tend to be balanced to achieve uniform precipitation. After the grain slowly soars, it enters the period
After supercooling, the grain is cooled to the storage temperature and then discharged from the grain discharge section. Mobile grain dryer performance characteristics:
1. The equipment has a simple structure, small size, and is easy to operate. It does not require auxiliary equipment and is easy to transport and move.
2. Using hot air as the drying medium and adopting the circulation drying process, the grains will be heated and dehydrated evenly and fully, and the quality after drying will be good.
3. The mobile grain dryer can use coal, electricity, rice husk or straw, etc., and convert it into clean hot air through a heat exchanger.
4. It has small investment and low usage cost. It can automatically control the working process, automatically shut down, and is simple and labor-saving to operate. It meets the needs of small and medium-sized farms and farmers.
5. Equipped with automatic online temperature measurement and humidity measurement devices, the degree of automation is greatly improved and the drying uniformity is good.
6. Easy to clean, no mixing of seeds, suitable for drying grain seeds.
7. The drying effect is good, with no discoloration, no pasty smell, no impurities, etc.
8. The heat source can be coal, electricity, waste materials, straw, etc. The drying cost is low.
9. The discharge port can be lengthened according to customer needs, and can be directly transported to the transport vehicle or directly bagged.
Instructions for use
The machine is first assembled and the power cord is connected (this drive cabinet requires a three-phase four-wire power supply).
1: First refuel the fan bearing box and then turn on the power, then debug and run the grain dryer. After everything is normal, measure the initial moisture of the dried grain, and combine grains with similar initial moisture into one batch. According to the initial moisture content of each batch, According to the situation, the drying process should be reasonably arranged.
2: Close the induced draft fan valve and turn on the induced draft fan. After the fan is normal, slowly open the valve.
3: After the fan runs smoothly, start the elevator. (Conveyor 2)
4: Start conveying 1. Start slowly adding the wet food.
5: Close the damper of the smoke exhaust fan and the stove for heating. Open the induced draft fan valve to support combustion and adjust it to the appropriate position.
6: (Exhaust fan on the left, conveying 1, conveying 2, smoke exhaust), the sensor is installed on the drying tower net.Mobile grain dryer performance characteristics:
