DW-Belt Dryer
카테고리: 대류 건조기
Continuous Convection Dryer with Mesh Belt:
The Belt Dryer can be configured with single or multiple mesh-belt layers, spreading material evenly for directional hot-air drying. Belt speed adjusts to each material's temperature and moisture content, so it runs at comparatively low temperatures while continuously processing large batches.
- Input:
- Permeable solids in sheets, strips, granules or blocks
- Output:
- Sheet, strip, granule or block solids with 3%–8% moisture content
- Temperature:
- Inlet air temperature < 200°C
- Additional Feature:
- Cooling
HZG-Rotary Kiln
카테고리: 대류 건조기
Perfect for Large-Scale, Continuous Drying:
Wet material enters at one end of the Rotary Kiln, where internal flights agitate it and blend it thoroughly with hot air. This elongated drum dryer, spanning many metres, can process hundreds of tons per hour, and its drum speed adjusts from 1 to 10 RPM to suit different requirements.
- Input:
- Granular materials
- Output:
- Granules with 3%–5% moisture content
- Temperature:
- Inlet air temperature range of 40°C to 350°C
- Additional Feature:
- Mixing
GXP-Closed Circulation Spray Dryer
카테고리: 대류 건조기, 분무 건조기
Optimal Drying for Sensitive Materials:
This explosion-proof spray dryer operates in a sealed environment, using inert gas as the drying medium to fully recover solvents from raw materials. The recyclable drying medium provides superior protection for sensitive materials.
- Input:
- Solutions, Emulsions, Suspensions
- Output:
- Powder with 3%–8% moisture content
- Temperature:
- Inlet air temperature range of 100°C to 300°C

- Anaerobic, explosion-proof and low-temperature conditions
ZLPG-Extract Spray Dryer
카테고리: 대류 건조기, 분무 건조기
Specialized Spray Dryer for Extracts:
The Extract Spray Dryer features a cylinder equipped with a cooling system specifically designed for drying extracts while keeping wall temperatures below 80°C. It includes an airbrush that cleans the walls during operation to prevent adhesion and protect the powder from burning.
- Input:
- Extracts (Liquid)
- Output:
- Extracts (Powder) with 3%–8% moisture content
- Temperature:
- Inlet air temperature range of 140°C to 180°C

Designed for temperature-sensitive and slightly viscous materials, this equipment offers a wide range of uses for loose solid materials. Its modular design allows drying and grinding stages to be added to meet varying customer requirements.
- Input:
- Non-viscous, loose solid materials
- Output:
- Powder, granules, with 3%–6% moisture content
- Temperature:
- Inlet temperature < 200°C
- Additional Feature:
- Grinding
LZG-Spiral Vibrating Dryer
카테고리: 대류 건조기, 진동식 건조기
Method for Drying Pellets and Granules:
The Spiral Vibrating Dryer dries materials by using centrifugal vibration and gravity to move them in a bouncing path from top to bottom along a spiral bed. Fresh hot air enters from below, interacting thoroughly with the material for heat and mass transfer before leaving through the top — ensuring even drying.
- Input:
- Granular, short-rod and spherical solids with < 20% moisture
- Output:
- Granules, short rods and spheres with 3%–5% moisture
- Temperature:
- Inlet air temperature < 100°C

- Cooling
분무, 플래시 및 킬른 방식 전반에 걸친 열풍 직접 접촉
대류 건조는 열풍과 소재 간의 직접 접촉을 통해 열을 전달합니다 — 분무 건조기(LPG, YPG, GXP, ZLPG)는 액체를 열풍 흐름 속으로 미립화하고, 플래시 건조기(XSG, 공기식)는 습윤 케이크를 빠르게 흐르는 열풍 속에 분산시키며, 트레이(CT-C), 벨트(DW), 킬른(HZG) 및 진동식(LZG) 건조기는 벌크 고체를 열풍 환경 속으로 이동시킵니다.
대류 열전달의 장점
열풍이 가열된 표면을 거치지 않고 소재와 직접 접촉하므로 건조 속도가 빠릅니다. 액체, 슬러리부터 과립, 벌크 고체에 이르기까지 다양한 원료 형태에 적용할 수 있습니다. 소규모 배치 트레이 건조부터 대규모 연속식 킬른 또는 벨트 설비까지 손쉽게 확장할 수 있습니다.
