Dec 11 2014 Spray drying the choice dehydration method for the food and pharmaceutical industries employs an atomizer and a stream of hot gas to produce dry powders granules or agglomerates from a liquid or slurryThe atomizer disperses liquid feed into fine droplets from which the liquid evaporates leaving behind solidsProducts dried using this process include powdered milk cake mix instant.

Dedert’s new Spray Dryer is also enhanced with an innovative gas disperser to ensure optimum contact between the heated drying gas andBefore entering the drying drum at a temperature in excess of 800176F.

Depending on the design of the drum dryer the product is applied continuously as a thin film on the underside or top of the main drumAs the drum rotates and is heated on the inside the product dries on the outside of the drum surfaceThe short exposure to a high temperature reduces the risk of damage to the productThe water or solvent evaporates and leaves the process at the topIf necessary the vapour can also be sucked off locally around the drumThe dried product film finally reaches the knife and is scraped off.

SYSTEM The Sakav steam heated Drum Dryer is noted for its high thermal efficiency in the removal of water andor solvents from a wide range of solutions slurries and suspensionsThe ratio of steam consumption to evaporation can be as low as 1.

Drum Drying also known as Roll Drying is a continuous process that creates dry powders and flakes from a liquid feedstockThe liquid feed is sprayed onto or in between two rotating drumsThe drums are heated internally with steam to increase the surface temperatureAs the material is sprayed onto the drums it sticks and dries to the surfaceTo obtain the desired specifications the drum8217s rotation speed steam pressure and the gap between the drums can be variedThe dried material is peeled from the drums using a knife system.

DrumDrying Process ampamp IngredientsIn the drumdrying process pur ed raw ingredients are dried over two rotating highcapacity drums and undergo a validated kill stepSheets of drumdried product are milled to a finished flake or powder formDrumdried ingredients reconstitute immediately and retain their flavor color and nutritional value.

Dry high solids viscous foodgrade materials into flakes that can be milled down to your desired particle size.

Drying equipment uses various methods to remove moisture from and preserve a productCommon in the pharmaceutical and food industries dryers employ methods such as freezing vacuum heat and more.

For better wear resistance the thermal spray coating is a perfect alternative to chromium coating with the same properties in terms of surface finish and heat transferThe combination of hardness and the dense structure of the layer makes the thermal spray coating less sensitive to impact damage and provides better protection against acidic products.

For handling large volumes of solutions spray dryers are unsurpassed and it is only at feed rates below 01 kgs that a drum dryer becomes more economicIndeed the economy of spray drying improves with capacity until at evaporative capacities of greater than 06 kgs the unit running cost is largely independent of scale.

Frain has a variety of dryer equipment in stockWe have vacuum freeze drying equipment for the reliable preservation of a wide range of pharmaceutical and chemical productsThis includes both standard and customized drying equipment including vacuum freeze dryers shelf dryers freezers fluid bed drum rotary spray and conveyor dryers.

May 13 2021nbsp018332Advantages of Drum DryerDrying takes place in less timeIt is suitable for thermosensitive drugsTo reduce the temperature of drying the drum can be enclosed in a vacuum chamberRapid drying takes place due to rapid heat and mass transfer.

Our thermal spray coating technique for drum dryers by means of highvelocity air fuel HVAF provides a dense layer harder than chromium yet more ductile and highly wearresistant which guarantees a long life cycle and is available for all makes and models of contact drum dryers regardless of whether it is for a new machine or as upgrade to an existing one.

Spray dyer is composed of a huge round drying chamber with a small coneshaped base made up of stain less steel with the size of the drying chamber variations in between 25 to 9 m and also elevation is 25 m or even moreThe spray disk atomiser is regarding 300mm in size and also turns at a rate of 3000 to 50000 changes each minutes.

Two sets high speed centrifugal spray dryers and three sets of drum.

Comparison of methods and advantages and disadvantages of spray dryer.

The drying speed is fast and the surface area of the material liquid is greatly increased after atomizationIn the hot air flow 95 98 water can be evaporated instantly and the drying time is only 535 secondsIt is especially suitable for the drying of heat sensitive materials.

Spray Dryers are relatively simple in operation which accept feed in fluid state and convert it into a dried particulate form by spraying the fluid into a hot drying mediumRotary dryers feed material into a tumbling or rotating drum or tumblerThe drum is then heated or heated air is fed into the unit.

For more than 50 years DORST TECHNOLOGIES has planned supplied and installed all over the world customized spray drying plants for the processing of waterbased suspensions to produce dry powders or granules capable of being pressed which are used in a wide variety of applications in all kinds of industries.

Spray drying of viscous suspensions combines efficient granulating by means of atomization with careful drying of the droplets in flight by means of a hot gas atmosphereThis procedure enables to produce precisely conditioned powder qualities and materials for most various requirements.

Steam heating gives a uniform temperature distribution over the drum surface and this results in a consistent product qualityThe steam condenses on the inside of the drying drumThe condensate is continuously removed from the drum so that the largest possible surface area remains available on the inside of the drum for condensation of the steamThe steam system is a closed system which means that the product cannot come into contact with the steam or condensate.

The drum body of the drum dryer is heated on the inside by steamA special composition of cast iron gives the drier a combination of favourable properties accurate shape retention even at high steam pressure and temperature and excellent scraping properties for the scraping knife.

The release profile will differ based on the material characteristicsSome materials will dry into a powder others as flakes and some will coil up as a cigar roll before full separation from the drumOnce the material releases an inline hammer mill will reduce the size down to the desired particle sizeThe final powder is then transferred to a baghouse and conveyed through a screener where it is finally packaged into bags or boxes.

This is one of the most preferred configurations used for the production of pharmaceutical granules on an industrial scaleIt allows complete integration with the help of upstream and downstream equipmentIn addition it is also equipped with a wet mill between the granulator and dryerIt becomes very easy to load mix and granulate a second batch in the high shear granulator with modern control systems whilst the previous batch is dried in the fluid bed before dischargeThe cleaning of all equipment is done in a single automatic process.
