Characteristic

Principle of Drying: The air generated from the air blower is converted into hot air through the heating units (heater, etc.). This air is mixed with the materials to be dried in the dryer to form supersaturated steam. This steam then passes through the bag filter (dust collector), and again passes through the cooler (refrigerating machine). Within the cooler, the supersaturated steam eliminates moisture due to the temperature difference, and the circulation system allows air without the moisture to move to the air blower again and back to the heating units. (Refer to Figure 1)
Closed Loop System: Since the drying process is completely sealed, the drying can be done with water contents up to 0.01% without energy release, environmental pollutants release and dust generation. In addition, moisture can be collected in the heat exchanging part, which is very advantageous if using expensive raw materials. Furthermore, it is possible to add specific fragrance to the materials to be dried. Because the process is sealed, the unique taste or fragrance can be maintained (indeed, the system can be opened according to the demand of the user)
Homogeneous Drying: In the inner mixing units, the materials being dried are repeatedly contacted with heat through fluid movements. Accordingly, all materials inside are homogeneously dried, and with the soft action of the machine, the materials can be dried without any damage.
High Efficency System: Since the drying per unit time is greater compared to that of other dryers, itis a highly efficient drying system.

• 인건비 항목은 자동화로 인한 감소 효과이며 경우에 따라 달라 질 수 있다.

• 분쇄기 손실분은 기존 건조 생산방식이 열풍만 이용하여 건조 후 파우더 형태가 아니므로 다시 분쇄 공정을 통하여 가루 형태로 만들때 발생하는 경우이다.

Multiple Usage: The machine can be used for mixing, spraying / coating, heating, sterilizing, cooling, and granulating within one process. Furthermore, because it is possible to control the temperature and humidity freely, production automation is possible, which can reduce losses due to overfilling and over-drying.
Field of Application: Food, Pharmaceuticals, Detergents, Plastic, Feed, Metal Powder, Ceramics, Building Materials, etc.
Drying Inert Gas: If it is the case that some physical properties of the material to be dried require drying with different gases, note that this is possible. However, the experimental conditions may be changed depending on the gas to be replaced.
Various Models: Depending on your conditions of usage, from FD-20 (20Liters) to FD-8000 (8000Liters) models are all applicable.
테스트: 당사에서 보유하고 있는 FD-20, FD-120모델로 언제든지 실험가능하며 피 건조물의 함수율 및 온도 변화 등을 확인 할 수 있다.; 단, 건조실험을 실시하는 경우 TEST비용이 발생하기 때문에 이는 테스트 요구자가 실비를 부담하여야 한다.
