影響干燥機效果的因素及設備特點

干燥機由主機、空氣處理系統(tǒng)、加熱系統(tǒng)、控制系統(tǒng)等組成。工作時，物料加入干燥機的料斗，按工藝要求設定程序和參數(shù)，整機開始工作。空氣經(jīng)過空氣處理系統(tǒng)過濾、經(jīng)加熱系統(tǒng)加熱后進入主機，物料經(jīng)熱空氣流化，水份迅速蒸發(fā)，物料被快速干燥。

The dryer is composed of main machine, air handling system, heating system and control system. When working, the material is added into the hopper of the dryer, the program and parameters are set according to the process requirements, and the whole machine starts to work. The air is filtered by the air treatment system and heated by the heating system before entering the main engine. The material is fluidized by hot air, and the water evaporates rapidly, and the material is dried rapidly.

按設定的程序與參數(shù)完成操作后，將料倉推出與提升轉料機扣合提升出料，有效地控制粉塵與交叉污染。設備處于密閉負壓下工作，且整個設備內(nèi)表面光潔，無死角，易于清洗，符合“GMP”要求。

After the operation is completed according to the set procedures and parameters, the silo is pushed out and connected with the lifting transfer machine to lift the discharge material, so as to effectively control the dust and cross pollution. The equipment works under closed negative pressure, and the inner surface of the whole equipment is smooth and clean without dead angle, which is easy to clean and meets the requirements of GMP.

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(nèi)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(nèi)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(chǎn)品質量。

The dryer can directly dry liquid materials, and has many functions such as fast drying 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.

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。可防止物料因余熱過度而變質，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。

?? the dryer has cold air post-treatment process, and the dried materials 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，露點，時間和氣流。

?? generally speaking, there are four factors affecting the drying effect, namely drying temperature, dew point, time and air flow.

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，干燥溫度對終干燥效果的影響也有重要的影響。

The drying temperature of the 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 final drying effect.
