Product Description SD-DW Series Dry Wind Spray Dryer is suitable for processing preparation of bacteriophage microcapsules, Protein feed, Creatinase, Yeast, Drosophila pupae, Lactitol, Mannitol, Graphene modified solution, Various traditional Chinese medicines, microcapsules, ACD, PF, TQB3720, collagen powder, etc.working PrincipleCOMPARATIONDry methodFreeze DryerDry Wind Spray DryerDrying mechanismVacuum sublimationDew point differenceDrying environmentVacuumNormal pressureDrying temperature< -20oC35oC-60oCVacuum sublimation stateSolution stateSolution atomization stateEvaporation surface areaSmallLargeDrying efficiencyPoor, generally >24 hoursHigh, generally about 3 secondsPowder stateBlockPowderedAccumulation thicknessRequired, generally cannot exceed 10mm, the thicker the thickness, the longer the drying time, the worse the drying efficiencyNoneConjunctival phenomenonWhen the solution is sublimated, the surface of the solution is prone to conjunctivaeion, which hinders the sublimation of waterNo conjunctival phenomenonInfluence on materialsLong drying time has a certain impact on biological stabilityShort drying time, relatively small impact on biological stabilitySafety parametersWhen the equipment is running, the noise level at the distance from the equipment operator (less than 1 meter) is below 75dBThere are obvious warning signs at dangerous partsComply with the requirements of equipment safety design specificationsDried sampleBasic parametersFeed rate: 50~2000ml/hMetal parts in direct contact with drugs must be made of 316L stainless steel, and other parts that do not contact materials, such as brackets, can be made of 304 stainless steel.The outside of the equipment can withstand 75% ethanol, 0.2% chlorhexidine and other disinfectants for wiping and disinfection, and can also withstand air disinfectants including 84, formaldehyde, ozone, hydrogen peroxide and acetic acid.The outside of the equipment can withstand 75% ethanol, 0.2% chlorhexidine and other disinfectants for wiping and disinfection, and can also withstand air disinfectants including 84, formaldehyde, ozone, hydrogen peroxide and acetic acid.Relevant data or operation records that need to be monitored and displayed online during the process, such as time, pressure (mechanical display), temperature, flow, alarm information, operation and program running process, can be printed out. The monitoring interface should include the equipment operation status (such as: preparation, operation, shutdown, etc.), the system program operation process, the data during the equipment operation (such as: temperature, pressure, air volume, etc.), the connection of the corresponding pipelines and valves, the feed pump, and the status of the atomizer opening and closing (which can be displayed on the dashboard). It is necessary to equip the feeding system, including Lange peristaltic pump and Lange feed pipe.It is necessary to equip the atomization drying system, including atomizer, air compressor, pressure regulating valve, drying tower, perspective mirror, etc.It is equipped with an inlet temperature sensor with a detection range of 0-250oCIt is equipped with an exhaust temperature sensor with a detection range of 0-150oCIt is necessary to equip the product recovery system, including cyclone separation, collection barrel or cup (316 stainless steel or glass), collection valve, etc.The electric control system is of Xinjie brand, and the electric control auxiliary system is of Schneider brandWith cyclone collectorExhaust dust collector: high temperature resistant bag filter or other suitable dust collector.Supporting equipment (if any): dew point meter (Michel brand)The equipment needs to adopt appropriate design to prevent static electricity and prevent product dust from escaping from the equipment system to the operating space and surrounding environment.Discharge collection valve: The interface is a clamp-type quick connectionAuxiliary equipment should be brought by itself, such as air compressor, dew point meter, cold water circulation unit, etc. The installation site only provides civil water and electricity public engineering facilities, and the system should be guaranteed to operate normally after installation.CONFIGURATIONNameBrandDrying towerSUS316LCyclone separationSUS316LReceiving barrelSUS316LCyclone collectorSUS316LAtomizerU.S. spraying systemAir compressorTaiwan DolphinRegulating valveFang WeiExhaust dust collectorWan ChuangBag dust collectorLi XiangTemperature sensorShanghai Jia Min (intake and exhaust)Power supplyTaiwan Mean WellElectronic control auxiliary systemSchneiderElectrical control systemPLC Xin JieConnecting clampGui Yong BrandRelaySchneiderDisplay screenLGBlowerTaiwan DagangPeristaltic pumpLangePeristaltic pump feed pipeLangeHeating coreHongdeDry air system two-stageLABSPRAY?Dew point meterMichellChilling water circulation unitComsonExhaust dust collectorLABSPRAY?Automatic dehumidification systemLABSPRAY?Automatic switching deviceLABSPRAY?Humidity detectorLABSPRAY?Leakage protection deviceLABSPRAY?Overvoltage stabilizing protection deviceLABSPRAY?Temperature curve memory functionLABSPRAY?Plywood PackingOur factory
