3、cal Principle Dwg.1. 概述 GeneralLPG型高速离心喷雾干燥机，主要用于使稀溶液、乳浊液、悬浮液、浆状物料、熔融液及中药浸膏等物料喷雾干燥成干粉。具有速度快、效率高、工序少等优点。对热敏性物料可保持其色、香、味。干粉溶解性好，纯度高，该型喷雾干燥机可广泛用于塑料、染料、轻工业、化肥、食品、医药，特别是热敏性物料，如牛奶、药物、染料等工业领域广泛使用。 LPG High-speed Centrifugal Spray Dryer mainly used for the drying of materials such as weak solution, emulsion

4、, suspending liquid, slurry, melt-water, Chinese herbal extract etc. to dry powder. It has advantages of high speed and efficiency as well as less process. For thermal sensitive material, it can keep its color, scent and taste. Dry powder has good solubility and high purity. This kind of dryer has w

5、idely application on industries such as plastic, dye stuff, light industry, fertilizer, food-stuff, pharmaceutical especially for heat-sensitive materials such as milk, medicine, dye stuff etc.2. 工作原理Working PrincipleLPG喷雾干燥机是将需雾化的料液直接干燥成固体粉粒的过程。干燥是传热和传质同时进行的过程。在干燥过程中，前一种是液滴中水分的蒸发，主要是热交换过程。当进入降速干燥阶段

6、后是颗粒的干燥，主要是扩散过程。物料离开干燥室时所含的水分与前一瞬时所接触的空气的相对湿度有关，物料的最终产品水分不可能低于该相对湿度下相应的平衡水分。产品的最终水分应受与其最后接触空气的相对湿度控制，是扩散控制中的湿度梯度控制，这三个控制阶段构成了喷雾干燥过程。 The drying procedure of LPG spray dryer is the drying from atomized slurry to powder directly and the heat transfer and medium transfer are carried out at the same tim

7、e. During drying, water evaporation of droplet is in the process of heating exchange. When it is in lower speed granule drying, it starts the process of diffusion. The water content of discharged material from drying chamber is related to the previous air relative humidity. Final moisture of materia

8、l must not lower than the balance moisture under relative humidity. Final moisture is controlled by the last time moisture humidity contacting with air and is a humidity gradient control of diffusion control, and these three control stages constructed spray drying process.已经加热至需要温度的空气以切线方向进入热风分配器，经热

9、风分配器作用后的空气均匀地、螺旋式地进入干燥室，同时料液由雾化器雾化为伞状细小的雾滴，当雾滴与热空气混合接触后传热传质，这时高温气流与高含水率的雾滴相遇，水分迅速汽化。干燥后产品从燥室锥底进入风管随空气流入旋风除尘器,大部分物料被分离，少量细粉继续进入布袋除尘器被收集,最后尾气由排风机排出系统外。 Heating air to required temperature and entering into hot air distributor in a tangent direction, and then evenly goes into the dryer chamber in a scr

10、ew type. At the same time slurry is atomized to umbrella-type fine droplet by atomizer, then it start heat and medium transfer after mixing contact between droplet and hot air. At the same time high temperature air flow contact with high moisture droplet, and then moisture start evaporating quickly.

11、 Dry material discharged from bottom cone goes into cyclone separator along with air flow in the duct where most of material will be separated, a small amount of fine will be further collected in the bag filter and the off-gas will be discharged by exhaust fan.本机组采用并流式喷雾干燥，液滴与热风方向并流流动。虽然热风温度较高，但由于热风

12、进入干燥室立即与雾化液滴接触，干燥室内温度急剧下降，不会使被干燥物料过度受热，特别适宜热敏性物料干燥。排出产品的温度一般低于排风温度1020左右。This set of equipment is in a concurrent flow spray drying which slurry and hot air direction will flow concurrently. Although hot air temperature is much high, because of the immediate contacting between hot air in the chamber

13、 and atomized droplet, temperature in the drying chamber will decrease rapidly thus material will not be over heated, and this is especially applicable for the drying of thermal sensitive material. The temperature of discharged products is usually 1020 lower than air discharge temperature.雾化器旋转方向与热风

14、旋转方向相同，采用逆向旋转。 Rotary speed of atomizer has the same direction with hot air rotation, both are reversal rotating.3. 设备特点Equipment Feature本设备参照中华人民共和国机械行业标准JB/T8714-1998离心喷雾干燥机的规范进行制造。This equipment is fabricated according to Chinese standard JB/T8714-1998 of Centrifugal Spray Dryer.干燥塔锥体角度设计成小于等于60，
