DW-Belt Dryer
カテゴリー: 熱風乾燥機
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
カテゴリー: 熱風乾燥機
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
カテゴリー: 熱風乾燥機, スプレー乾燥機
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
- Suitability:
- Anaerobic, explosion-proof and low-temperature conditions
ZLPG-Extract Spray Dryer
カテゴリー: 熱風乾燥機, スプレー乾燥機
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
- Additional Features:
- Freeze dehumidification, Air brush for tower cleaning
Pneumatic Flash Dryer
カテゴリー: 熱風乾燥機, フラッシュ乾燥機
Integrated Handling for Heat-Sensitive, Loose Solid Materials:
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:

LZG-Spiral Vibrating Dryer
カテゴリー: 熱風乾燥機, 振動式乾燥機
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

スプレー、フラッシュ、キルン方式における熱風直接接触
対流乾燥は、熱風と材料を直接接触させることで熱を伝達します。スプレー乾燥機(LPG、YPG、GXP、ZLPG)は液体を熱風気流中に噴霧・微粒化し、フラッシュ乾燥機(XSG、気流式)は湿ったケーキ状材料を高速で流れる熱風中に分散させ、棚段式乾燥機(CT-C)、バンド式乾燥機(DW)、キルン乾燥機(HZG)、振動式乾燥機(LZG)はバルク固体を熱風環境の中で移動させます。
対流伝熱の利点
熱風が加熱面を介さず材料に直接接触するため、乾燥速度が速い。 液体・スラリーから顆粒・バルク固体まで、幅広い原料形態に対応可能。 小規模なバッチ式棚段乾燥から大規模な連続キルン・バンド式設備まで、容易にスケールアップできる。
