The conventional spray dryer is typically operated with rotary atomizer or high-pressure nozzles for atomization of the concentrate. It is generally used for conventional food and dairy products.
When the product leaves the drying chamber and the cyclone, it is collected in a pneumatic con-veying and cooling system.
This type of dryer is referred to as a one-stage Dryer, as the powder, when discharged from the chamber, has its final moisture content. For further reading please refer to Milk Powder Technology - page 71. Many food & dairy products – depending on their composition – need to be dried in this way. But for products like milk and whey it is possible to perform the drying in two or more stages by replacing the pneumatic conveying and cooling system by VIBRO-FLUIDIZER™. designed for second-stage drying.
The conventional spray dryer can now be operated in such a way that the moisture content in the powder, when it leaves the drying chamber at a higher moisture content than desired in the final powder. This is done by atomizing more concentrate into the same amount of primary drying air, which will then be utilized much better. For final drying in the VIBRO-FLUIDIZER™ a small amount of drying air at low temperature is needed. The overall energy consumption per kg of final powder is reduced by as much as 20%. For further reading please refer to Milk Powder Technology page 131.
If the fines fraction from the cyclone and/or bag filter is returned to the atomization device, it is possible to produce agglomerated products instantly soluble in cold or warm water. For further reading please refer to Milk Powder Technology page 153.

Vrieco-Nauta vacuum dryers were developed from the already successful conical screw mixer line. The superior mixing quality of the Vrieco-Nauta mixers is utilized to efficiently present fresh product to the heated surface area. Heat is transferred into the product through a jacketed vessel wall causing solvents or moisture residues to evaporate. The entire vessel is run under vacuum to further aid in moisture removal by lowering the saturated vapor pressure.

The Krauss-Maffei Helix Dryer BD is a special variant of the helical mixer dryer HD.
A study group including leading european pharmaceutical manufacturers and KMPT developed a joint requirement profile providing the benefits of different drying equipment in one machine. The Krauss-Maffei Helix Dryer BD offers major benefits in comparison to conventinal drying systems in the production of active pharmaceutical ingredients.
It is designed for the processing of small batches that requires a precisely controlled operating environment and total product containment. Key features of the dryer are its compact dimension for mobility and the optional setup with a central drying station hosting drive unit, vacuum connection and heating/ cooling supply in combination with a stationary lifting device and multiple, mobile product vessels with vapor filters.
By connecting the product vessels with appropriate isolation valves to a mechanical separation equipment such as Krauss-Maffei Pharma Centrifuge, the product remains fully contained throughout the complete processing sequence. Different dryer vessel sizes can be connected to the central drying station for added operating flexibility. No product transfer is required from the filtration step to the drying/ mixing operation and to the final discharge point which can be provided with various high-containment devices. The entire process train can be placed on one individual floor or inside a single clean room.
Main Applications
API's, antibiotics, amino acids, pharmaceutical intermediates, fine chemicals.

Vacuum dryers are used for parts with complicated form or which do not tolerate the higher temperature of hot-air dryers. Combined dryers with hot-air and vacuum or infra-red and vacuum are used with light weight parts that do not posses enough heat to evaporate the water in vacuum. The vacuum dryers can be equipped with pneumatically operated door and automatic valves.

DRUVATHERM® Vacuum Shovel Dryer
Intensive mixing prevents temperature and moisture gradients in the product
High heat transfer means more effective drying
Gentle thermal treatment of the product under vacuum
Multiphase process (mixing, granulating, drying, cooling)
Economical solvent recuperation
Machine Type
Lödige DRUVATHERM® Shovel Dryers are batchprocess vacuum dryers. The main shaft with shovels is regulated by frequency converter to achieve an optimal adjustment to the process. The special mixing elements rotate in the cylindrical drum, which is equipped with a heating/cooling jacket, and generate a three dimensional movement of the product (mechanically generated fluid bed). The resultant frequent contact of particles with the heat transfer surface reduces the drying times to a minium.
Standard Configuration
The product movement creates an intensive contact of individual product particles with the heated wall of the machine and at the same time treats the product as gently as possible. Rotating choppers, installed inside the drum, provide additional dispersion during possible product transition phases and are available as an option. Fine particles in the solvent vapours are collected by a pneumatically cleaned filter mounted on the machine and are returned to the product bed for drying.

The ES Junior series of continuous vacuum driers are the ISVE mini-driers traditionally used by small craftsmen.
They enclose all the technology and experience developed over twenty years of research into the application of the vacuum process in the treatment of wood.
The machine, operating at low temperatures, allows the timber to lose its water content without subjecting it to thermal changes which can cause cracking and warping.
The evaporated water which remains in suspension in the container keeps the drying material surface continuously humidified, avoiding in this way the formation of small cracks which, in other drying systems is quite frequent.
The humidity level which is necessary between environment and material is constantly maintained by a condenser which precipitates the steam in suspension.

In general, after vibro-abrasion, the parts are wet and must consequently be dried.
Several solutions are then possible among those, the most used here:
- Vibrating driers of the series G
- Driers of series BF-HL

Vibration Dryer Chuo Kakohki System
Mixing by vibration - no internals
Low mechanical stress - minimum product abrasion
Vacuum drying - low temperatures
Simple design - easy operation
No dead space, very good accessibility - quick cleaning
Machine Type
The vibation dryer provides thorough mixing of the product - essential for good drying results - simply by vibration of the drum. No mixing elements are used meaning the product is mixed and dried gently. Seals are not required for rotating parts therefore, even under vacuum, there is minimum leakage and the dryer can be operated at low jacket temperatures. The simple design of the machine guarantees easy handling and very good reliability.
No internals, the excellent accessibility and stainless steel construction of all product contact parts make the dryer easy to clean - an important criteria for processing batches of different products.
Standard Configuration
The vibration dryer, comprised of a vertical vessel with jackets for heating and insulating, vibrates on a supporting structure.
The vibration of the dryer - induced by unbalance motors at the foot of the vessel - causes controlled, elliptical movement of the material to be dried around the vessel axis. This fluidizes the product. The continuous, radial flow carries the product along the heated wall where the heat transfer takes place. This accomplishes an excellent drying result.
