Airflow dryer is an efficient and fast drying equipment, which is based on the principle of instantaneous drying, by using the rapid movement of heat-carrying air to drive wet materials, so that the materials are suspended in hot air. This design intensifies the entire drying process and significantly increases the rate of heat and mass transfer. After airflow drying materials, its non-binding moisture can be almost completely removed, such as starch and other materials, even if the water content of the feed is as high as about 40%, after airflow drying, the moisture content of the finished product can also be reduced to 13About 5%.
Another significant advantage of the jet dryer is that it does not deteriorate the material it dries. Compared to conventional dryers, the output of air dryers is also significantly improved, which means that users can complete more production tasks in less time, resulting in higher economic efficiency in the short term.
Airflow dryers have a wide range of applications in different fields. For example, in an ammonium sulfate crystal drying system, an airflow dryer is used to further dry ammonium sulfate crystals with a water content of 7% to 05% or less. The whole system includes multiple links such as MVR device crystallization, centrifuge spinning and air drying, and finally the dried materials are packed in tons of bags. In addition, the system is equipped with a bag filter for dust removal to ensure a clean production environment.
In addition, the airflow dryer is also used for the drying of tetrasodium ethylenediaminetetraacetic acid (Nax) filter cake. In this system, the remaining moisture of the cake-shaped wet material is dried after passing through the air flow drying unit, and the dried Nax solids are subsequently packaged in big bags. This system can dry up to 0 Nax wet materials with a moisture content of 30%.Less than 8%, it can process 700kg of material per hour. The control system of the whole system adopts DCS centralized control, which realizes automatic control including temperature, liquid level, pressure, flow rate, etc. All rotating equipment can be started and stopped through DCS, and large rotating equipment such as fans and pumps can also be started and stopped on site.
In summary, the air dryer has been widely used in many fields due to its high efficiency, fast speed, and no material deterioration. Whether it is the drying of ammonium sulfate crystals or tetrasodium EDTA, the airflow dryer has shown its unique advantages and brought significant economic benefits to users.
