Working Principle of Tower Dryer
1.The tower dryer is a metal steel structure. It is arranged from top to bottom and is divided into multiple sections such as grain storage, drying, slow revival, reversing, re-drying, cooling, and grain discharge. The hot air enters the tower from the middle wind chamber, and is evenly distributed to each inlet box after passing through the air distributor. After heat and mass exchange in the grain layer, it is discharged out of the tower through the damp box. Metal shutters are installed at the damp outlet to achieve environmental protection and have no effect on atmospheric airflow dehumidification.

2.The heat exchanger, drying tower and hot air supply pipeline are all made into double-layer metal shells, with refractory rock wool insulation in the middle to improve the drying effect. The wind and smoke pipelines are equipped with smoke and air temperature controllers to adjust the hot air temperature, flow rate and total pressure parameters to ensure the ideal operation of the drying operation.

3.The induced draft fan of the tower dryer is arranged at the smoke exhaust port of the lower smoke box to form a negative pressure in the smoke path in the heat exchanger, and the blower is arranged at the air inlet of the heat exchanger to form a positive pressure state in the heat exchanger to ensure the purity of the hot air.

Main Features of Tower Dryer

1. The tower dryer has a simple structure, small size, easy operation, no auxiliary equipment required, and is easy to transport and move.
2. The tower dryer is easy to clean and will not mix seeds, which is particularly suitable for drying grain seeds.
3. The tower dryer has a small investment and low operating cost. It can automatically control the working process and automatically stop. It is simple and labor-saving to operate, which meets the needs of small and medium-sized farms and farmers.
4. The tower dryer uses coal, rice husks or straw as fuel, which is converted into clean hot air through combustion and heat exchange, and does not pollute the dried grains.
5. The tower dryer is equipped with automatic online temperature and humidity measurement devices, which greatly improves the degree of automation and has good drying uniformity.
6. The tower dryer uses hot air as the drying medium and adopts a circulating drying process. The grains are heated and hydrated evenly and fully, and the drying is good.
