GPQ小型噴霧干燥實驗機，將噴霧干燥、流化床干燥、噴霧造粒、蒸發(fā)濃縮、氣流干燥等多種工藝操作，集中到一臺占地不到0.5平方米的實驗機上，相對于生產(chǎn)性設(shè)備，投資少、成本低、設(shè)備體積小、占地面積少、處理量小、操作靈活多變；滿足科研以及企業(yè)新產(chǎn)品開發(fā)的需求；適合于大學、科研院所、企業(yè)等從事新產(chǎn)品研發(fā)，特別是昂貴產(chǎn)品的實驗研究?？蓮V泛應(yīng)用于生物、化工、醫(yī)藥、食品、染料、輕工和農(nóng)藥等領(lǐng)域的噴霧、造粒、蒸發(fā)等干燥加工過程。
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 upying 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 upation 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.
噴霧干燥過程：漿料經(jīng)過蠕動泵送至氣流式噴嘴，空氣由鼓風機引入電加熱器，加熱后經(jīng)布風板由塔頂進入塔內(nèi)，與由噴嘴霧化的漿料霧滴進行質(zhì)、熱交換，完成瞬間蒸發(fā)和瞬間干燥，從而得到干粉顆粒，較粗干粉從塔底排出，較細干粉經(jīng)旋風分離器回收，微粉由布袋除塵器收集后排空。
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.
流化床干燥過程：空氣由鼓風機引入電加熱器，加熱后經(jīng)布風板進入流化床，物料由流化床頂部預(yù)先加入，通過調(diào)整進風量，使物料在熱空氣的作用下保持流化狀態(tài)，實現(xiàn)物料的流化干燥。干粉產(chǎn)品由旋風分離器收集，尾氣經(jīng)布袋除塵器除塵后排空。
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小型噴霧干燥機又名實驗型噴霧干燥機，實驗室噴霧干燥機，主機體長700mm，寬700mm，高1600mm，由兩部分組成，左半部分為電加熱器，主要用于干燥過程中換熱介質(zhì)的加熱；右半部分為自動控制系統(tǒng)，采用臺達觸摸屏，PLC自動控制系統(tǒng)，可對實驗過程中進出風溫度、風量、干燥時間進行設(shè)定，并自動控制。通過在主機上安裝不同的配套組件，可實現(xiàn)對溶液、懸濁液、糊狀物等物料的噴霧干燥、流化床干燥、氣流干燥、噴霧造粒等工藝過程，得到粉狀產(chǎn)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 ording 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
