This series of units can be customized according to customer requirements for heat sources, including options such as electricity, steam, heat transfer oil, natural gas, and coal. The heated dry hot air and wet materials are mixed at a specially designed feeder (positive or negative pressure), allowing the wet materials to mix and move with the high-temperature airflow, and finally, the moisture is separated from the raw materials through a separator.
This series of units is a drying equipment developed by our company by integrating a series of advanced domestic and international technologies and continuous improvements. It features a multi-layer fixed hollow heating circular material-carrying plate, rotary rake stirring, and vertical continuous operation, primarily using heat conduction. The drying process involves passing the heat carrier into the hollow circular plates on each layer, indirectly heating the wet material placed on the plate surface through heat conduction. Under the scraping action of the rotating rake blades, the continuously moving and tumbling material's moisture evaporates at the operating temperature. The steam is discharged with the equipment's exhaust gases, thereby continuously obtaining qualified dried products at the bottom of the equipment. Compared with traditional drying equipment, it has advantages such as high thermal efficiency, energy saving, uniform drying, good product quality, small footprint, fewer auxiliary devices, less pollution, continuous production, easy operation, and wide applicability.
This equipment is based on the fluidized bed drying principle and has been innovatively designed according to the properties of the materials to be dried. It is particularly suitable for drying wheat and corn germ.
The FGLS series mixed-flow grain drying tower produced by our company is an advanced drying machine model developed based on the digestion and absorption of foreign drying technology and the use of computer mathematical simulation design for grain drying. The unit consists of grain unloading, lifting, cleaning, conveying, pre-drying bin, drying tower, post-drying bin, heat source, control unit, and other components. The material passes through a multi-functional drying zone, combining the advantages of concurrent flow, counterflow, and mixed-flow drying towers to achieve continuous, gentle, and uniform wet-heat exchange, avoiding dead spots and scorched grains. It features automatic control, allowing arbitrary adjustment of the material's residence time within the tower. It has characteristics of high drying temperature, strong drying capacity, low unit energy consumption, and uniform and stable product quality.
Our company has absorbed and integrated advanced foreign technologies, and developed the FGDF series "Negative Pressure Airflow Drying System" tailored to China's specific conditions. After more than ten years of industrial application trials, it has been promoted and applied in the drying of starch, protein powder, and wet rice bran, and has won the "Second Prize of Henan Province Science and Technology Progress Award".
