In the field of drying, Piovan has developed the application of an innovative technology: the use of a rotor with a honeycomb structure to eliminate the humidity released by plastic material during the drying process.
This brand-new series, presented for the first time at the K2007 show, consists of four models that operate in a temperature range from 80 to 150°C, with air flows from 50 to 200 m³/h: HR50, HR100, HR150 and HR200.
The new HR dryers present numerous advantages such as:
• No expense for the connection of cooling water or compressed air and no running costs for such services because the HR units require only electric power supply;
• 50% reduction of the use of energy;
• Stable Dew Point, featuring set-up values in a range down to -50°C;
• Easy access to all machine components allowing Simplified maintenance
• Guaranteed absence of dust and of material contamination, making the HR dryers suitable for application in the medical and optical sectors too;
• Continuity of operation of the honeycomb rotor ensured by the new drive mechanism furnished with a wear-resistant Kevlar reinforced belt which eliminates traditional maintenance operations or lubrication, necessary when using rudimental belts or chains.

The dehumidication of small and average-sized quantities of polymers may be perfectly carried out with the DD 30 and DD 60 series dehumidifiers. Although these machines have only one silicate cartridge, if the plant is correctly dimensioned, it is possible to easily reach DEW POINT even at 40°C. The temperature control of the dehumidification process is assured by microprocessor system, with a visualization on the panel of the operations carried out and alarms in progress. Silicate regeneration is entirely automatic, the cycle times being personalized by the manufacturer for each machine with the hopper capacity with which it has been fitted, thereby obtaining the maximum efficiency with the least energy expenditure. The original graphics of the control panel facilitate the operator in setting the optimum process temperature, also indicating the minimum stay time in order to obtain a good dehumidification of each material.

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.

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.

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.
