Lab Spray Dryer

The new and simple addition to the laboratory spray dryer market

MODEL ESDT1 LAB SPRAY DRYER

European SprayDry Technologies LLP launched their latest model spray dryer at the Powtech Exhibition in Nuremburg in Germany last month and in a step away from their traditional high end bespoke larger capacity spray dryers the latest offering is aimed at the R&D and academic markets.

The goals for the design team was to produce a lab spray dryer that could operate anywhere, assembled with ease whilst retaining an operational simplicity to allow even relative novices to produce powders quickly and easily.

 

 

The production machine appears to have met all aspects of the designers’ aspirations, being able to operate in any location with a single phase electricity supply, even home kitchens, requiring no additional pumps or compressors which are integral to the unit.

The machine has a main body fabricated from enamelled panels in which all mechanical component including peristaltic pump, fan unit and compressor are contained. A stainless top mounting bracket connects the intake air tube to the chamber. The unit is supported by base plate with rubber feet.

The main drying components are manufactured from borosilicate glass 3.3. due to its high corrosion resistance and clarity of glass, these include the chamber, conveying tube and cyclone. The glass components connect by push fit clamps while the chamber is locked in place using a sanitary main clamp.

The final component is an electrical panel that slips onto the side of the main body and connects with jack plugs. The power supply is a standard 13A single phase plug for mains connection. A simple collection bottle screws onto the cyclone powder discharge.

Space requirements for the machine is a lowly 0.2m2 of bench space and the whole machine can be assembled by a single person in less than 5 minutes.
Atomisation is by two fluid nozzle located above the chamber with push in connections for air and liquid, the nozzle typically produces a range of particle sizes from 3 micron to 70 micron with the Sauter mean diameter being 47.4 micron, this based on water pumped at 1 bar and an air feed of 1.1 bar, this will differ dependent upon feed concentration, viscosity and air pressure.

As you would expect from Euro SprayDryers both chamber and cyclone are highly efficient and effective.

Ease of operation, how simple can you make it, plug in the machine, switch on the fan, adjust the air flow using a speed dial, switch on the heater, allow the machine to heat up in the meantime prepare your solution. Once at temperature inset the feed tube into the jar of solution, switch on the compressed air and adjust using regulator, finally switch on the pump and increase the speed using the speed dial, as simple as we can make it.

For those requiring a higher degree of sophistication the machine comes with CALgrafix Process Monitoring Software as standard. This windows based user interface provides logging, charting, recording, alarms, networking and full configuration options

The electrical heater is capable of producing drying temperatures up to 200oC which allows the drying of most products.
The machine is highly adaptive with a bag filter option and closed circuit currently in development and hope to be launched in the New Year. Customisation of the machine is also available where customers require special adaptations.

Organic Flavour Spray Dryer

Organic Flavour Spray Dryer

European SprayDry Technologies commissions its latest spray dryer for organic flavour manufacturing in Spain.

The plant, a tall form spray dryer with nozzle atomiser and secondary cooling is producing a range of spray dried encapsulated flavours and fruit juices.

The order was awarded to European SprayDry Technologies in the face of stiff competition from other European manufacturers. Plant versatility and uncomplicated operation were key factors in the sale.

The plant was a bespoke dryer, designed specifically to meet the specifications of customer and prevailing climatic conditions, dictating special consideration for some products.

Spray Dryer for FlavoursThe plants, a model 6 – 12 flavour dryer, featured direct gas firing heating, pressure nozzle atomisation, cyclone separation and a vibratory powder cooler on the powder discharge.

A standard feature common to all ESDT flavour dryers is the high sanitary filtration system which incorporates HEPA filtering of all non heated process air.

Pressure nozzle atomisation was chosen due to its high versatility in flavour production giving greater control over the bulk density and other particle properties, as well as very good performance in colour retention.

This spray dryer represents the latest in a long line of flavour dryers designed by European SprayDry Technologies, satisfying a growing market.

Increased Production at Express Contract Drying

Express Contract Drying, one of the United Kingdom’s largest Toll Manufacturers of food products, has recently increased their production facility with the commissioning of a new spray drying plant at their Ebbw Vale plant in Wales.

The plant, a 100kg/hr Tall Form spray dryer, was designed and manufactured in the UK by the Harlow based company European SprayDry Technologies.

The turnkey plant incorporates a hygienic purpose built mixing area complete with jacked tanks, mixers, transfer pumps and pipe work. Feed material is pumped at high pressure into the chamber and atomised using nozzle atomisation; the nozzle atomiser being ideally suited to flavour production.

The spray dryer itself is a conventional Co-Current design with direct gas heating. Direct gas was chosen specifically for energy conservation and being the most efficient form of heating for spray drying plant.

The drying chamber was individually design to ensure maximum production capability into a small footprint, fitting within a modern factory unit whilst retaining the considerable advantages of the Tall Form drying chamber for food production.

Tall Form Spray DryerThe chamber is fitted with powder dislodgment hammers and a top air sweep door manufactured from thick stainless steel and fully TIG welded and internally polished.

Powder is conveyed directly from the chamber base to a high efficiency cyclone where process air and powder are separated. Powder is discharged from the cyclone through a disentrainment hopper and rotary valve prior to sieving and packing. The spent system air is discharged through a Venturi scrubber then passed through a final packed tower removing any remain dust particles and cooling the exhaust gasses reducing the environmental impact from the process.

The plant is an all stainless steel construction with the internal surfaces polished to food quality whilst the external finish is in bright satin. The all stainless steel construction allows the plant to cope with the frequent meticulous cleaning regime employed between by ECDL between products where several washes can take place over the course of 24 hours.

The in-house designed control system allows the process to be operated in both a manual or automatic mode and is in keeping with ESDT’s high specification for food production dryers with the plant being fitted with HEPA filtration for all non heated process air.
