Whether the product is a wet powder or a slurry, specially designed feeders transfer the product into the dispersion section of the dryer. A high speed rotor disperses the product in the drying zone. An induced hot gas stream as high as 600 °C provides the energy for instantaneous evaporation of the moisture within the feed material. Evaporation capacity of the largest unit is over 6000 kg/hr. Dried particles enter the classifying zone at the top of the dryer and fine de-agglomerated particles leave the dryer outlet to be collected down stream. Coarse particles are rejected by the classifier and are returned to the dispersion zone for further processing.

Vertical Vacuum Dryers
The Proceco Vacuum Dryer is a top-loading vertical cylinder with a hydraulically operated clamshell-type lid. The dryer is designed to operate in conjunction with a Proceco Turntable Parts Washer.
Components are transferred from the parts washer to the drying chamber immediately after the cleaning cycle is completed, while the parts are still very hot. The vacuum in the drying chamber will cause the moisture to evaporate completely with the heat stored in the components..
Horizontal Through-Fed Vacuum Dryers
The horizontal vacuum dryer is a through-fed design with automatic operated sliding doors at each end, and integrated conveyor loading and unloading system.
Components are transferred from the parts washer to the drying chamber immediately after the cleaning cycle is completed, while the parts are still very hot. The vacuum in the drying chamber will cause the moisture to evaporate completely with the heat stored in the components. Drying cycles are a fraction of those associated with convection-type dryers.

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.

Vacuum belt / band driers consist of a housing with built-in conveyer belts for the product running over heating plates. Automatic belt control ensures precision belt operation. The belts run parallel to one another and a metering pump with oscillating application nozzle is assigned to each individually controlled belt.
The shift in the boiling point under vacuum provides for a low evaporation temperature and therefore gentle product temperature.
Pumpable products usually run through a highly viscous, frequently sticky phase during the drying process. This formation of vapor bubbles in the product results in a dry cake on the belt toward the end of the drying process. The temperature to which the product is subjected during the drying process has a significant effect on the achievable product quality. The belts run over a number of heating zones and over a cooling zone at the end. Steam, pressurized water or thermal oil can be used for heating; each zone can be controlled separately, allowing the temperature of the heating surfaces to be adapted to the specific requirements of the product.

Drum Dryers are available in single and double drum models. Single drum units may be dip or splash fed, or equipped with applicator rolls. The latter is particularly effective for drying high viscosity liquids or pasty materials such as mashed potatoes, applesauce, fruit-starch mixtures, gelatin, dextrine-type adhesives, polyacrylamide, synthetic resins, and various starches.
Double drum dryers are the most versatile and widely applied. These dryers are used to dry many food, chemical, and pharmaceutical materials of widely varying densities and viscosities: dilute solutions, heavy liquids, pasty materials, or fairly heavy sludges. The movable drum permits complete control of product film thickness. Feed may be by perforated tube trough, pendulum, or special engineered devices.

FLUID BED DRYER DESIGN
The rectangular fluid bed dryer system, CONTACT FLUIDIZERTM incorporates back-mix and plug flow sections. A rotary distributor disperses the wet feed evenly over the back-mix section equipped with contact heating surfaces immersed in the fluidized layer.
The heating surfaces of this fluid bed dryer are designed to avoid deposits and obtain a high heat transfer in the fluidized layer, and they provide a significant portion of the required energy.
Fluid Bed Dryer - CONTACT FLUIDIZER
Therefore it is possible to reduce both the temperature and the flow of gas through the system. This is particularly important for heat sensitive products.
Specially designed perforated gill plates allow handling of oversizes and minimize powder holdup by grade changes.
The heating panels can be inspected or cleaned externally.
Cleaning in place (CIP) of the whole plant is often provided.
Subsequent plug flow sections are used for postdrying and cooling, if required.
ADVANTAGES
Advantages of the CONTACT FLUIDIZERTM - compared to fluid beds without heating surfaces, two-stage flash/fluid bed dryers, or rotary dryers - include its compact design, high thermal efficiency, and low gas throughput
