The disc continuous dryer is a highly efficient and energy-saving continuous drying equipment. The equipment mainly includes a casing, a frame, a hollow heating plate, a main shaft, an arm and a rakes, a feeder, a discharge device, a reducer and an electric motor.
High thermal efficiency and short drying time. The tray continuous dryer is a heat conduction drying device, and there is no disadvantage that hot air takes away a large amount of heat during hot air drying. At the same time, due to the mechanical action of the eucalyptus leaves, the material is continuously stir-fried and stirred, so that the thermal resistance of the material layer is lowered and the drying strength is improved, and the thermal efficiency can reach more than 60%. Due to the different moisture content of the material, the unit steam consumption is 1.3-1.6kg steam/kg water. The drying time is related to the initial moisture content of the material and the nature of the material, generally 5 to 80 minutes.
2. Low energy consumption. Taking our company's products as an example, the heating plate has a diameter of 1500mm, and the heating and drying area of ​​the 14~16 layer heating plate is 19~22m2. The driving motor power is only 3.0kw, the diameter is 3000mm, and the 14~16 layer heating plate has a heating and drying area of ​​84. ~96m2, its drive click power is only 11kw.
3. Good regulation. By adjusting the spindle speed, the material residence time can be precisely controlled; each layer can be individually heated or cooled to heat or cool the material, and the material temperature is controlled accurately; by adjusting the thickness of the feed layer on the heating plate, the spindle speed, 耙The leaf form and size optimize the drying process.
4. The material to be dried is not easily damaged. Although this is a stirring and drying device, it is a low-speed agitation. Due to the low rotation speed of the eucalyptus leaves, the material is not easily broken during the frying process, and is particularly suitable for drying the materials required for the crystal form of the product.
5. The environment is clean and tidy. Because it is a closed operation, there is no dust flying, which improves the working environment and is beneficial to the health of the operators.
6, stable operation, no vibration, low noise, equipment upright installation, small footprint.
Second, the scope of the disc continuous dryer
Any type of drying equipment has a certain range of application due to its own characteristics, and the disc type continuous dryer is no exception.
In terms of the properties of the material, the dryer is suitable for drying loose materials and is not suitable for viscous or paste materials. This is because the dried material is continuously stir-fried under the action of the eucalyptus leaves, and is pushed forward by the eucalyptus leaves, and the viscous or paste-like materials are difficult to be sautéed by the cilantro, and even crusted on the drying tray, so that the stalk leaves cannot function normally. Even damaged. However, after continuous exploration and experimentation, by increasing the back-mixing device, the disc continuous dryer has successfully solved the drying of the viscous and paste materials, and the application range thereof has been expanded.
In terms of the thermal properties of the material, various materials can be dried using the equipment. This is because the dryer can use steam, heat transfer oil or hot water as a heat source, and the dryer can also be designed in various forms such as a normal pressure type, a closed type, and a vacuum type. Therefore, whether the heat sensitive material or the material requiring a higher drying temperature can be dried by the device.
As far as the industry is concerned, the equipment can be used in many industries such as chemical, pharmaceutical, food, food, dye, synthetic resin, feed, fertilizer and so on.
