Product DescriptionPaddle dryer1. Core featuresConduction heating principleThrough hollow paddle (jacket + shaft) dual-channel heat transfer oil/steam heating, the thermal efficiency can reach 80%-90%High viscosity processingSpecial wedge-shaped paddle design, maximum processing viscosity up to 500,000 cP (such as petroleum sludge)Self-cleaning functionThe gap between the rotating paddle and the shell is ≤0.5mm to prevent material adhesionLow oxygen environmentThe closed structure can achieve nitrogen protection, and the solvent concentration is controlled to be <50%LEL2. Key technical parametersEvaporation intensity: 8-12kg water/m2·h (normal pressure type)Final moisture content: 0.5%-15% (adjustable)Working temperature: 80-320℃ (depending on the heat transfer medium)Energy consumption index: 2800-3500kJ for evaporating 1kg of waterSpecificationPaddle dryerSpray dryerApplicable materialsPaste/viscous materials (viscosity > 10,000 cP)Solution/suspension (solid content <60%)Processing capacity0.5-30 tons/day (wet basis)100kg-100 tons/day (evaporation water volume)Heat source costLow (thermal oil recycling)High (direct electric heating consumes more energy)Occupancy areaCompact (horizontal structure)Requires high-altitude plant (tower height 8-25 meters)Maintenance costPaddle blades need to be replaced regularly (2-3 years)Frequent maintenance of atomizer precision partsTypical industriesChemical/Environmental/MineralsFood/pharmaceuticals/new materialsInvestment cost$500,000-3 million (medium-sized equipment)$2-20 million (large scale difference)Product DescriptionSpray dryer1. Core featuresAtomization technologyCentrifugal (15000-25000rpm), pressure (20-40MPa), airflow (compressed air assisted)Instant dryingThe surface area of the droplets increases ten thousand times, and the water evaporation rate reaches 100kg/h·m2Morphology controlThe finished particle size is adjusted by atomization parameters (D50 range 10-300μm)Thermosensitive protectionWhen the inlet air temperature is 200℃, the actual heating temperature of the material is only 60-80℃ (actual measurement in milk powder production)2. Key technical parametersEvaporation capacity: 5-5000kg water/h (industrial model)Thermal efficiency: 50-70% (with waste heat recovery system)Final moisture content: 0.5%-5% (free water is basically removed)Energy consumption index: 4000-5500kJ for evaporating 1kg of water (conventional model)3. Functional advantagesControllable shapeCan produce special shapes such as hollow spheres (ceramic microbeads) and porous structures (instant coffee)Aseptic processingCIP/SIP system to meet the GMP requirements of the pharmaceutical industry (such as antibiotic drying)High degree of automationIntegrated online particle size analyzer (such as Malvern real-time monitoring), automatic adjustment of atomization parameters4. Application scenariosDairy products: whole milk powder production, air inlet temperature 180-200℃, maintain milk protein activityNew materials: nano zirconium oxide preparation, control particle agglomeration, specific surface area > 50m2/gPharmaceuticals: probiotic microcapsule embedding, survival rate > 90% (low temperature spray drying technology)Environmental protection: zero discharge of desulfurized wastewater, treatment of high-salt wastewater (TDS > 20%)Our AdvantagesFunctional advantagesOutstanding energy savingEnergy saving of more than 40% compared with traditional fluidized bed drying (measured data from a chemical plant)Continuous operationCan process continuously for 24 hours (a case of sludge drying project in a sewage treatment plant)Explosion-proof certificationATEX standard design, suitable for solvent-containing materials (such as acetone recovery in the pharmaceutical industry)Application scenariosHazardous waste treatment: oily sludge (water content 80%→15%), with condensation recovery system to achieve oil recyclingChemical industry: polyacrylamide (PAM) drying, final moisture ≤10%, avoid high temperature decompositionFood processing: yeast paste drying (temperature precisely controlled at 60±2℃), retaining active ingredientsMineral processing: bentonite drying, processing capacity of 5 tons/hour, heat source using direct gas combustionIndustry pain point solutions1. Paddle dryerAgglomeration problem: adopt reverse screw propeller design (application case of a titanium dioxide factory, agglomeration rate reduced by 80%)Thermosensitive materials: segmented temperature control (high temperature dehydration in the front section, low temperature drying in the back section), used for enzyme preparation productionCorrosive materials: spray tungsten carbide (hardness HV1200) on the surface of the paddle, life extended by 3 times2. Spray dryerStick problem: set air sweep device on the tower wallUneven particle size: multi-stage cyclone separation + bag dust removalHigh solid content: pressure nozzle + mechanical supercharger systemSelection suggestionsPreferentially choose paddle dryer: processing viscous materials, solvent recovery, site-limited scenarios(such as: petrochemical industry sludge treatment, pharmaceutical industry high viscosity extract drying)Preferentially choose spray dryer: require good product fluidity, need to control particle morphology, heat-sensitive materials(such as: functional milk powder production, nanomaterial preparation, instant beverage processing)Company ProfilePacking & DeliveryCertificationsFAQ1.
