影响沸腾干燥机干燥效果的因素及设备特点

沸腾干燥机能直接将液态物料干燥、具有快速干燥颗粒、粉状物料等多种功能。装物料的料斗是锥形，可增加物料的流速，便于流化，物料在料斗内不易形成死角，物料吸受热量均匀，烘干速度快。装物料的料斗内备有取样装置，可随时取样，以测试物料的干燥的干燥终点，保证产品质量。

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.

沸腾干燥机有冷风后处理工艺，干燥后的物料可及时通冷风冷切。可防止物料因余热过度而变质，确保了物料烘干质量。采用特殊材料进行空气热过滤，以防散热器的异物及空气中的杂质进入物料，确保物料的干净纯洁。沸腾干燥机设计了特殊的气体分布板，使载热气流横向呈螺旋状进入，使沸腾起的物料流分接触载热气流，吸受热量均匀，物料干燥快。减少了蒸汽消耗，节约了能源。

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.

一般来说，影响干燥效果的四个因素，即干燥温度，时间和气流。

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

沸腾干燥机的干燥温度也是一个重要因素。热量是打开聚合物之间的水分和水分的关键。当高于一定温度时，水分子和聚合物链会大大降低重力，水蒸气会被干燥的空气吹走。因此，干燥温度对干燥效果的影响也有重要的影响。

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.

干燥时间不能忽视。相关供应商应规定材料在适当的温度下干燥所需的时间。由于吸收热量和水分子扩散到颗粒表面，在颗粒周围的空气中需要一些时间，干燥时间会在一定程度上影响材料的影响。

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.

材料在干燥过程中，热空气将热量传递到干燥仓中的颗粒，从颗粒表面除去水分，并将水分送回烘干机。这一次，一定有足够的空气将树脂加热到干燥温度并保持一段时间的温度。

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.
