1. The difference in structure
(1) The air intake direction of the flash dryer is tangential air intake, and the rotating wind speed in the drying section is determined by the air intake speed, which is always an indefinite value. The rotating wind speed of the ultra-fine powder dryer is a high-speed rotating crushing disc. The rotating wind speed of the power is not interfered by the system, thus ensuring reliable production and stable product quality.
(2) The boiling dryer uses a control valve to adjust the air to be heated by a heat exchanger. Due to the effect of wind pressure, the material is dried instantly. At the same time, it adopts a multi-layer filter, which is efficient, safe and reliable in quality.
(3) The boiling dryer adopts a unique silencer device to reduce production noise. It is environmentally friendly and scientific and provides convenience for the search for production locations.
(4) The grading device of the boiling dryer is a rotating device with adjustable speed, while the grading device of the flash evaporator is actually just a grading ring. Although the rotary flash drier has also been improved, the classification ability is still not as good as the super boiling Dryer.
2. Scope of application
(1) Boiling drying machine powdery and granular materials in medicine, chemical industry, food and other industries.
(2) The flash dryer is only used for liquid materials
3. The difference in performance
(1) Boiling, drying and closed negative pressure operation, the air flow is filtered. It is easy to operate and easy to clean. It is an ideal equipment that meets the requirements of "GMP". Stirring can be set freely to avoid the agglomeration of wet materials and the formation of channeling during drying, which is convenient and easy to operate. The fineness of the materials in the flash dryer can only reach a certain level and cannot be further controlled.
(2) Because the pulverizing function of the boiling dryer is much better than that of the flash evaporator and the application range is wide, the output is larger than the flash evaporator, and the product particle size is finer.
(3) The thermal efficiency of the boiling dryer is significantly higher than that of the flash evaporator, so energy saving is obvious. However, the flash dryer can effectively control the final moisture and fineness, and through the adjustment of the feeding, hot air temperature, and classifier, it can ensure that the moisture content and fineness of the product are uniform. It is the unique advantage of flash dryer.
4. Comprehensive comparison of drying effect
The advantages of using a boiling dryer are:
(1) The model is small and the area is small: the supporting device is small, and the noise reduction ability is strong, and it can be produced in the city.
(2) Strong drying ability, short time and energy saving
(3) Fast speed, strong production capacity, and automatic feeding and discharging design and production can be carried out according to your own requirements.
