Different materials need to be dried by different drying techniques. If the client chooses the drying equipment without considering the property of material, there will be a series of troubles. For instance, the product will have dry surface and wet inside (uneven humidity), or the product cannot be dried one-time.

High Viscosity and Humidity Material

The drying of high-viscosity and high-humidity material has been a difficult problem in drying industry. Due to its high viscosity and high humidity, it is difficult to be squeezed and dried. Thus, users should select a drum dryer specially designed for drying high-viscosity and high-humidity material. Only in this way, the dried material can have the good color, no burnt paste and no loss of nutrition.

How to make the high-viscosity and high-humidity material  be dried fast and efficiently? Here are some points users could pay attention.

1. Control the moisture of the material which is fed into the drum dryer.

The moisture content of high-viscosity and high-humidity material is around 45%. If users put them into the drum dryer directly, the production cost will be large. At the same time,it will bring a great pressure on drum dryer machine. The best way is to stack them in a well-ventilated place for about 15 days. Until the water content of the material drops to about 20%, then users can process them by using the rotating drum dryer.

2.Make a proper selection of the drum dryer dust catcher

Because the material has fine granularity and little density, it is easy to be carried away by airflow in the negative pressure state after drying. Then the fluid medium changes and the dusty gas has larger moisture. Therefore, the dust catcher shall be chosen according to the specific material process state. ( Recommendation: air-box pulsed jet cloth filter)

3. Pay attention to the seal of conveying equipment for dried products.

4. Select a high-efficiency combustion furnace for your drum dryer. 

The combustion furnace should be able to burn out the inferior coal. It also should have a convenient furnace type.

Based on the drying technology theory for high-viscosity and high-humidity material and the advantages of various drum dryers, Fote Machinery has carried out the new structural design on the material lifters, hot air distribution system, and feeding & discharging devices of new-type drum dryer. According to the given technological parameters, FTM engineers have carried out the material selection for the main parts of new-type drum dryer and completed the whole structure design.

If you have more questions on the drying of high-viscosity and high-humidity material or some rotating drum dryer needs, please consult FTM experts online freely. They will provide you with the most satisfactory solutions.
