Spray Drying Process Spray Dryers Spray Drying Technology.

A spray dryer as the name implies is a device for drying utilizing a sprayA spray dryer mixes a heated gas with an atomized sprayed liquid stream within a vessel drying chamber to accomplish evaporation and produce a free flowing dry powder with a controlled average particle sizeThe unit operation of spray drying includes the.

A spray is created by contacting two fluids the feed and a compressed gasThe atomization energy is provided by the compressed gas usually airThe contact can be internal or external to the nozzleA broader particle size distribution is generatedThe average particle size produced for a given spray dryer feed is primarily a function of.

Spray Dryer Atomization Spray Drying.

Atomization can be provided by centrifugal wheels rotary atomizers pressure nozzles or twinfluid nozzlesThis range of systems allows the specific particle size requirements to be met for each application.

Closed circuit and selfinertized dryers are supplied to allow organic solvents to be dried and to meet the environmental specifications.

Direct or indirect heating systems are supplied depending upon the industry standards for the productInlet temperatures may range from 100°C for very heat sensitive products to 750°C for some inert chemicals.

During this same era the pharmaceutical industry has exploded with innovation — from the science of formulation to advancements in testing and beyondIt’s time for a spray dry transformation that meets the needs of modern pharmaceutical research and development.

However some products such as those dissolved or suspended in organic solvents cannot be dried using a common open cycle dryer in the presence of atmospheric air as such an attempt carries the risk of explosionHence closed cycle spray dryers are preferred for drying specific products such as carbide dyestuffs and pigmentsMoreover they leverage an inert gas eNitrogen to annul the risk of an explosion and the subsequent fireDue to all these factors the closed cycle segment is estimated to expand at the maximum CAGR of 7.

Moreover high energy consumption and toxic gas emissions associated with these equipment are turning out to be the major concerns for manufacturers as well as consumers particularly in the wake of the calls by various governments to ensure energyefficient industrial operations to curb the pollution levelsNevertheless technological advances are allowing manufacturers to develop products that are energyefficient and free from hazardous gases emissions which will open significant growth opportunities for the market.

Spray drying in the pharmaceutical industry.

Our spray dryers include small spray dryers laboratory spray dryers large spray dryers etc.

Spray drying technology dates back to the late 19th century but there has been little true innovation since its introductionSimilarly aside from perforated tablet coaters and the Wurster fluid bed in the 1950s solid dosage technology in the pharmaceutical industry has remained largely unchanged for well over a century.

Factors to be considered in spray drying process.

The atomizer forms the liquid into small droplets before spraying them into a hot air stream where the major part of the water evaporates in a few secondsAt the end the dried powder will be separated from the air by a cyclone andor a filter systemDownstream the dryer can be equipped with fluid beds coolers and agglomerators to further condition the powder prior to the packaging unit.

The global spray drying equipment market size was valued at USD 463 billion in 2018 and is projected to expand at a CAGR of 6Growing preference for functional and ReadyToEat RTE food products and focus of food processing companies on introducing products with enhanced shelflife are expected to drive the market growth from 2019 to 2025Rising product usage in the pharmaceutical and nutraceutical industries in the production of antibiotics penicillin enzymes and whey proteins is also expected to drive the market over the forecast period.

The open cycle segment accounted for the largest market share of more than 65 in 2018 and is likely to maintain the dominance in the years to comeIt is the conventional drying equipment and is preferred for several applications owing to the numerous advantages such as their ability to handle heatresistive and heatsensitive products availability in all sizes and capacities and low energy consumption.

The spray dryer has fast drying speed high efficiency few procedures and saves manpowerEspecially for heatsensitive materials the product quality is excellent but when the operation is unskilled and the adjustment control lacks experience it is easy to cause some problemsThe following is a summary of possible problems in production and their causes and remedial measures.

The spray dryer is a vertical parallelflow pressure drying equipment designed by our companyIts working principle is to disperse the material to be dried into very fine mistlike particles through mechanical action to increase the evaporation area of water and accelerate the drying process and after contact with hot air most of the water is instantly removed Removal so that the solid matter in the material is dried into powder.

The spray dryer sprays the material into droplets and disperses it in hot airThe materials are in contact with the hot air in a cocurrent countercurrent or mixed flow manner so that the water evaporates quickly to achieve the purpose of drying.

The VetterTec spray dryers are individually designed to meet the specific requirements of our customers and offer a high flexibility of design.

VetterTec offers spray dryers based on 40 years of experience and 180 references worldwide in the food and chemical industriesThe special knowhow in the design of the atomizers provides high reliability and a sophisticated solution to give the particle characteristics for the desired applicationFrom pilot plants to industrial units VetterTec provides a full range of spray drying units and services.
