影響沸騰干燥機干燥效果的因素及設備特點

沸騰干燥機能直接將液態(tài)物料干燥、具有快速干燥顆粒、粉狀物料等多種功能。裝物料的料斗是錐形，可增加物料的流速，便于流化，物料在料斗內不易形成死角，物料吸受熱量均勻，烘干速度快。裝物料的料斗內備有取樣裝置，可隨時取樣，以測試物料的干燥的干燥終點，保證產品質量。

Fluidized bed dryer can directly dry liquid materials, with a variety of functions such as rapid drying of particles and powder materials. The hopper for loading materials is conical, which can increase the flow rate of materials and facilitate fluidization. The materials are not easy to form a dead angle in the hopper. The materials absorb heat evenly and dry fast. A sampling device is equipped in the hopper for loading materials, which can sample at any time to test the drying end point of materials and ensure the quality of products.

沸騰干燥機有冷風后處理工藝，干燥后的物料可及時通冷風冷切?？煞乐刮锪弦蛴酂徇^度而變質，確保了物料烘干質量。采用特殊材料進行空氣熱過濾，以防散熱器的異物及空氣中的雜質進入物料，確保物料的干凈純潔。沸騰干燥機設計了特殊的氣體分布板，使載熱氣流橫向呈螺旋狀進入，使沸騰起的物料流分接觸載熱氣流，吸受熱量均勻，物料干燥快。減少了蒸汽消耗，節(jié)約了能源。

Boiling dryer has cold air post-treatment process, the dried material can be cut by cold air in time. It can prevent materials from deteriorating due to excessive waste heat and ensure the drying quality of materials. Special materials are used for air thermal filtration to prevent foreign matters in the radiator and impurities in the air from entering the materials and ensure the cleanliness of the materials. A special gas distribution plate is designed in the boiling dryer to make the heat carrying gas flow enter into the dryer in a transverse spiral shape, so that the boiling material flow contacts the heat carrying gas flow separately, and the heat absorption is uniform, and the material drying is fast. The steam consumption is reduced and the energy is saved.

一般來說，影響干燥效果的四個因素，即干燥溫度，時間和氣流。

Generally speaking, there are four factors affecting the drying effect, namely drying temperature, drying time and air flow.

沸騰干燥機的干燥溫度也是一個重要因素。熱量是打開聚合物之間的水分和水分的關鍵。當高于一定溫度時，水分子和聚合物鏈會大大降低重力，水蒸氣會被干燥的空氣吹走。因此，干燥溫度對干燥效果的影響也有重要的影響。

The drying temperature of boiling dryer is also an important factor. Heat is the key to opening the water and moisture between polymers. Above a certain temperature, water molecules and polymer chains will greatly reduce the gravity, and water vapor will be blown away by dry air. Therefore, the drying temperature also has an important influence on the drying effect.

干燥時間不能忽視。相關供應商應規(guī)定材料在適當的溫度下干燥所需的時間。由于吸收熱量和水分子擴散到顆粒表面，在顆粒周圍的空氣中需要一些時間，干燥時間會在一定程度上影響材料的影響。

Drying time cannot be ignored. The relevant supplier shall specify the time required for the material to dry at the appropriate temperature. Due to the absorption of heat and the diffusion of water molecules to the particle surface, it takes some time in the air around the particle, and the drying time will affect the material to a certain extent.

材料在干燥過程中，熱空氣將熱量傳遞到干燥倉中的顆粒，從顆粒表面除去水分，并將水分送回烘干機。這一次，一定有足夠的空氣將樹脂加熱到干燥溫度并保持一段時間的溫度。

During the drying process, the hot air transfers the heat to the particles in the drying bin, removes the moisture from the particle surface, and sends the moisture back to the dryer. This time, there must be enough air to heat the resin to the drying temperature and maintain the temperature for a period of time.
