See security protocol. series dehumidifying hopper dryers with process airflow up to 3000 cfm, low dewpoint to -100 F (average dewpoint -40 F), and pulse cooling technology. Units have a minimum of moving parts; clamps provide easy and quick access to the regeneration heater, process heater, and desiccant beds. Designed for safety and efficiency, heater packages use tubular elements, double-wall construction and insulation, reducing power consumption. Tubular heaters with low-watt density increase heater life. Multiple electric heater elements provide redundancy and extend heater life. DHD series comes with a PLC controller. Additionally, there are two expanded microprocessor controls available. All microprocessor controls feature SPI communications protocol capabilities, material saver, digital dewpoint monitoring, multilevel mul·ti·lev·el

UDC (Brit) n abbr (= Urban District Council) → Stadtverwaltung f series dehumidifying hopper dryers in four models ranging from 30 to 150 cfm. Standard features include microprocessor controls, material saver function with automatic temperature setback to a maintenance level, stainless-steel and aluminum internal components, mirror finish stainless exterior, digital dewpoint monitor, and SPI communications protocol. Standard configurations include hopper mount, floor mount with process air heater located in dryer enclosure, or floor mount with process air heater mounted remotely on the hopper for optimum efficiency. Dryers complement modular hoppers and combine to create modular drying systems in a variety of configurations.
AutoDry series hopper dryers have no moving parts and are simple to install and operate. Self-contained units with temperature ranges from 100 F to 375 F, 120 and 230 volts, and hopper sizes from 20 to 120 lb.
Gas Pack retrofit kit will convert expensive electrical units to low-cost natural gas. Unit is an easy bolt-on kit. Proprietary non-ceramic-woven metallic burner is designed for extended life span. Operation of the existing dryer is not affected. Gas Packs are available from 200 scfm/8kW to 4000 scfm/ 320kw. All kits available in standard temperature ranges from 175 F to 250 F, and high-temperature units to 375 F.
Dehumidifying desiccant dryers with microprocessor controller feature dewpoints of -40 F; electronic temperature control; process-air filter with cyclone and cartridge; cycle rates of 8, 12, and 16/hr; no moving parts except two four-way valves and the blowers; hopper clean-out door and large sightglass; 20 through 4000 cfm size range with hopper capacities to 25,000 Lb; direct-drive fans; location of desiccant inside towers and heaters outside in separate boxes; and drawer-type process-air heaters mounted externally.
Microprocessor-based control panel, which controls and monitors all dryer functions, available with graphic presentation. Process-air temperature selected manually and maintained with solid-state electronic temperature control.
Also hot-air dryers and preheater units for use with nonhygroscopic materials from 85 through 4000 cfm. Units have solid-state electronic temperature controls. Process heaters, mounted externally, are drawer-type that slide in and out. All units are compact, accessible from the exterior, and furnished with direct-drive fan.

Vibrating fluid-bed, Continuous dryers/coolers provide rapid drying and/or cooling. Vibration of the dryer, coupled with the fluid-bed design, provides a unit not sensitive to exact air flows or bed depths, while still providing "first-in-first-out" flow. Other features include ease of cleaning, negligible maintenance, and gentle handling of product with essentially no particle degradation.
WITTMANN ROBOT & AUTOMATION SYSTEMS, INC.
Closed-loop dryers equipped with individual, electrically operated switch over valves for each desiccant bed to avoid heat transfer between the drying and regeneration cycle and allow high efficiency of the process, as well as low dewpoint.

Turbo-Dryer has only two moving parts: tray/shelf assembly and fan assembly, both rotating independently in a fixed sealed housing.
Wet feed enters the Turbo-Dryer through a feed chute in the roof of the housing and flows onto the first shelf. Shelves are circular with cut-out center and radial slots and are rigidly mounted on an inner supporting frame, forming a vertical stack, which rotates slowly as a unit. Material flows onto each shelf from the one above, forming a pile. The rotation of the tray/shelf assembly carries the pile past a stationary blade set to level the pile to fill the tray at a uniform height. At the end of a revolution, the tray segment meets a second stationary blade set Lo wipe the tray clean of material. Material is held stationary by the wiper blade, while the tray continues its rotation. It flows through the radial slot onto the shelf below when the cycle is repeated and then progresses downward from shelf to shelf through thc dryer and is discharged through a chute the housing bottom.
Air or other drying medium is fed to thc Turbo-Dryer through a side-mounted vertical manifold with control dampers. Air moves inside the dryer by centrifugal fans mounted on a single vertical shaft. Fan assembly fits into the shelf assembly, rotating independently of the shelves. Drying medium leaves the dryer through a roof exhaust.
Turbo-Dryer housing, totally sealed, encloses and supports both tray/shelf and fan assemblies; supports stationary parts of the dryer, wipers
