The Fluid Bed Dryer finds application in Pharmaceuticals, Bulk Drugs, Dyes & Chemicals, Phyto-Chemicals, Catalysts, Food Products & Starch derivatives, Pesticides etc.\n\n\nFresh air is drawn in by means of a fan. The air is then passed through a filter and heated to produce warm air by use of electric heaters. If the product contains a solvent or inflammable substances, the dryer must be operated using steam and provided with a flame-proof motor. The heated air passes through the product container which has diffuser plates and a sieve. Due to the stream of air, the wet product gets fluidised. The material gets surrounded by the hot air and gets dried due to heat transfer. Moist air passes through a filter bag and an exhaust duct. The Fluid Bed Dryer is not suitable for drying of liquids or pastes.\n\n\nWe are among the most trusted firms, engaged in manufacturing, supplying and exporting Fluid Bed Dryer Machine. Designed in compliance with international quality norms, these products are manufactured using quality components and material, procured from the reliable vendors of the market. We also have R&D experts who conduct regular researches to improvise our Fluid Bed Dryer Machine.\nFeatures:\nSturdy construction\n\nLow maintenance\n\nEasy installation and low power consumption\nFurther Details :\n\n• Trolley system provided with the machine is SS-316 constructed\n\n• Supported by automation and PLC control\n\n• Provided with expansion chamber that feature the guide support\n• Lifting jack, which is housed in an inlet lower chamber, is made of Stainless Steel\n\n\nWorking Principle:\n\n• The dryer suck the atmospheric air via micron filter and balanced fan driver\n\n• Provide clean air passes over electric heaters/ steam\n\n• By the process of fluidization, the hot air passes through the product\n\n• The dryer is provided with dehumidifier support\n\n• The blower speed is controlled through an AC frequency drive that assists in controlling fluidization and avoids the choking of filter bag\n\n• To avoid lump formation in a container and achieve uniform fluidization, the ranking system is provided\n\n\nAdvantages :\n\nIn a Fluid Bed Dryer, the temperature is distributed uniformly throughout the product and the heat rate is very high. High production rates are achieved because of reduced drying time. As the product is in close contact with the drying air at a low temperature and for a short duration, the physical and chemical properties of the product are not affected generally and hence the dryer can be effectively used in the case of heat-sensitive products. As the product is continuously moving during the drying process, there is minimal lump formation or case hardening.\n \n\n \n\n\n\nSee More-\n\n", "price": 0.0, "discountamount": 0.0, "currencycode": "INR", "priority": 1000000, "isfreeshipmentavailable": false, "shipmentduration": 7, "_keywords": [ "hot air", "warm air", "clean air", "Fresh air", "Moist air", "dry cakes", "dryer suck", "high speed", "filter bag", "dry powder", "wet product", "R&D experts", "exhaust duct", "micron filter", "Food Products", "filter presses", "drying process", "bound moisture", "Low maintenance", "diffuser plates", "atmospheric air", "Smooth operation", "electric heaters", "fluid bed dryers", "flame-proof motor", "Bed Dryer Machine", "Working Principle", "product container", "optimum efficiency", "quality components", "AC frequency drive", "High functionality", "Starch derivatives", "Optimum performance", "Sturdy construction", "inlet lower chamber", "reduced drying time", "uniform fluidization", "dehumidifier support", "free flowing material", "low power consumption", "High production rates", "robust infrastructure", "intermediate handling", "industrial experience", "single stage operation", "inflammable substances", "minimal lump formation", "international quality norms" ], "isarchived": false, "isavailable": true, "applicationid": null, "productindex": 14, "imageuri": "https://productimages.withfloats.com/actual/58e096b308051728e8dfa6c2.jpg", "tileimageuri": "https://productimages.withfloats.com/tile/58e096b308051728e8dfa6c2.jpg", "images": null, "totalqueries": 0, "gpid": null, "groupproductid": null, "createdon": "2017-04-02T06:14:11.108Z", "updatedon": "2018-08-08T18:46:25.428Z", "buyonlinelink": null, "producturl": "http://WWW.SPRAYDRYERINDIA.IN/products/fluid-bed-dryers-/14", "availableunits": -1.0, "iscodavailable": true, "isprepaidonlineavailable": false, "maxcodorders": 0, "maxprepaidonlineorders": 0, "uniquepaymenturl": null, "brandname": null, "category": null, "tags": null, "variants": false, "keyspecification": null, "otherspecifications": null, "pickupaddressreferenceid": null, "paymenttype": "UniquePaymentUrl", "producttype": "products", "hsncode": null, "gstslab": 0.0, "isnotforsale": false }, { "_id": "5b6b3a804d9966054cd7495e", "fptag": "SPRAYDRYERHYDERABAD", "merchantname": null, "customwidgets": null, "externalsourceid": null, "name": "Spray Drying Plant:", "description": "Spray Drying Systems Manufacturer:\n\n \n\nWe have designed spray drying plants that is also based on single stage operation and extensively used to convert solutions, suspensions and slurries into dry powder within a few seconds without any intermediate handling.

This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying medium; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used.[1]\nAll spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disk and single-fluid high pressure swirl nozzles. Atomizer wheels are known to provide broader particle size distribution, but both methods allow for consistent distribution of particle size.[2] Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process needs, drop sizes from 10 to 500 µm can be achieved with the appropriate choices. The most common applications are in the 100 to 200 µm diameter range. The dry powder is often free-flowing.\nThe most common type of spray dryers are called single effect. There is a single source of drying air at the top of the chamber (see n°4 on the diagram). In most cases the air is blown in the same direction as the sprayed liquid (co-current). A fine powder is produced, but it can have poor flow and produce a lot of dust. To overcome the dust and poor flow of the powder, a new generation of spray dryers called multiple effect spray dryers have been produced. Instead of drying the liquid in one stage, drying is done through two steps: the first at the top (as per single effect) and the second with an integrated static bed at the bottom of the chamber. The bed provides a humid environment which causes smaller particles to clump, producing more uniform particle sizes, usually within the range of 100 to 300 µm. These powders are free-flowing due to the larger particle size.\nThe fine powders generated by the first stage drying can be recycled in continuous flow either at the top of the chamber (around the sprayed liquid) or at the bottom, inside the integrated fluidized bed. The drying of the powder can be finalized on an external vibrating fluidized bed.\nThe hot drying gas can be passed in as a co-current, same direction as sprayed liquid atomizer, or counter-current, where the hot air flows against the flow from the atomizer. With co-current flow, particles spend less time in the system and the particle separator (typically a cyclone device). With counter-current flow, particles spend more time in the system and is usually paired with a fluidized bed system.
