微型流化床干燥

GPQ微型多功能干燥实验机，将喷雾干燥、流化床干燥、喷雾造粒、蒸发浓缩、气流干燥等多种工艺操作，集中到一台占地不到0.5平方米的实验机上，相对于生产性设备，投资少、成本低、设备体积小、占地面积少、处理量小、操作灵活多变；满足科研以及企业新产品开发的需求；适合于大学、科研院所、企业等从事新产品研发，特别是昂贵产品的实验研究。可广泛应用于生物、化工、医药、食品、染料、轻工和农药等领域的喷雾、造粒、蒸发等干燥加工过程。

GPQ mini multifunction experimental dryer centralizes suchvarious processes as spraying drying, fluidized bed drying, fluidized bed spray granulation, evaporation and concentration, and pneumatic drying onto a single machine occupying less than 0.5 square meters. Compared with productive equipment, it has a good many merits as follows, low investment and cost, small bulk, less occupation and throughput, and flexible operation. It is suitable for the demands of the new products development of the college, scientific research institution, enterprises, especially the expensive products development. It can be widely used in the various drying processes in such the fields as biology, chemical, pharmacy, food, dyestuff, light industry and pesticide, etc.

喷雾干燥过程：浆料经过蠕动泵送至气流式喷嘴，空气由鼓风机引入电加热器，加热后经布风板由塔顶进入塔内，与由喷嘴雾化的浆料雾滴进行质、热交换，完成瞬间蒸发和瞬间干燥，从而得到干粉颗粒，较粗干粉从塔底排出，较细干粉经旋风分离器回收，微粉由布袋除尘器收集后排空。

Spray drying process:

Air is heated in electric heater through the fan, then goes into the spray dryer through the top. Slurry flows into pneumatic atomizing nozzle from liquid material tank by peristaltic pump, atomized into small droplets by the compressed air come from the nozzle. The small droplets spurt out downward, mixes with hot air of the drying chamber, along with water evaporating instantly. Slurry turns into fine powder in a moment by drying. The coarse powder is collected at the bottom of spray dryer, subsequently the fine powder is gathered in the cyclone. The exhaust air is discharged after recovery in the bag filter.

流化床干燥过程：空气由鼓风机引入电加热器，加热后经布风板进入流化床，物料由流化床顶部预先加入，通过调整进风量，使物料在热空气的作用下保持流化状态，实现物料的流化干燥。干粉产品由旋风分离器收集，尾气经布袋除尘器除尘后排空。

Fluidized bed drying process:

Air is heated in electric heater through the fan, then goes through the gas distributor into the fluidized bed dryer; and material enters the fluidized through the top. Materials keep fluidized in virtue of the flotage effect of the hot air. Energy and mass exchange in the fluid bed dryer. The exhaust air goes into the cyclone to recover the entrained dust, then discharges after the bag filter.

GPQ喷雾、流化床多功能实验机主机体长700mm，宽700mm，高1600mm，由两部分组成，左半部分为电加热器，主要用于干燥过程中换热介质的加热；右半部分为自动控制系统，采用台达触摸屏，PLC自动控制系统，可对实验过程中进出风温度、风量、干燥时间进行设定，并自动控制。通过在主机上安装不同的配套组件，可实现对溶液、悬浊液、糊状物等物料的喷雾干燥、流化床干燥、气流干燥、喷雾造粒等工艺过程，得到粉状产品。

GPQ multifunction mini experimental dryer’s main body is 700mm long, 700mm wide, 1600mm high, and consists of two major parts. The left part is the electric heater which is used for the heating of the air; the right part is the automatic control system, PLC, which can automatically control the inlet and outlet air temperatures, inlet air rate and drying time during the drying process according to the set value. By fixing various sets of subassembly onto the body, the processes of Spray Drying, Fluidized Bed Drying, Spray Granulation, and so forth, can be implemented, to gain powder products
