Portable Dryers provide higher capacities with greater flexibility while minimizing the investment. They may operate either dry & cool or all heat while cooling in properly equipped bins using LP or natural gas with many models able to use single phase electrical supplies. This design covers the smaller to middle capacity 5 point removal requirements from 220 to 2,450 BPH dry & cool and 420 to 4,000 BPH all heat. From a simple system with grain moved with augers to a more involved system with an overhead wet bin, drag conveyors, and bucket elevators, FFI’s portable dryer models are the most versatile. The low profile of the single module dryers work well with overhead wet bins, while the 8’-26’ basket lengths give growers the flexibility they need for capacity growth. Depending on the model, FFI’s optional grain inverters, heat recovery systems, and noise suppression systems can further enhance efficiency, quality, and environmental requirements in a high percentage of today’s growing farms.

• Entrelec Terminals: Color-coded Entrelec terminals are used for
all computer control circuits connections, making for easy installation, diagnosis and service.
• Safety Disconnect: For safely disconnecting power from main panel for servicing dryer controls.  Also provides an easy connection point for incoming electric supply.
FFI’S HIGH EFFICIENCY BURNER: FFI’s patent pending, high efficiency
burners provide superior heated airflow resulting in a cleaner flame,
increased fuel efficiency, and most importantly, lower operating costs.
Burner offers considerably improved flame sensing. An electronic ignition
system monitors the burner and a view window provides easy observation.
Maxon™ valves are used on all single module units which promote better
fuel flow. An electronic ignition system monitors the burner, and a view
window provides ease of observation.  Other features include an easy-to-adjust vaporizer, a large service access door, and an oil-filled gas pressure gauge.  This burner was developed in FFI’s research and testing facility at the Assumption, IL plant. Air flow and static pressure were exactly duplicated in state of the art test stands with Air Movement and Control Assoc. Int.(AMCA) specification air flow test chambers so the testing would not be limited to the fall drying season. Improvements were made in efficiency, flame stability, and flame sensing over our previous and other industry burner designs.
COMPOSITE POLYMER FAN BLADES: FFI Portable Dryers feature axial fans with composite blades, which allow for a very low starting load, leading to easier starting and improved efficiency over centrifugal fans.  Composite blades also eliminate the need to continuously rebalance the
fan. Additional benefits of composite blades include high airflow across
a wide static pressure range, quiet operation, and reduced energy cost.
OPTIMIZED AIRFLOW TO 80 CFM PER BU.: Sized to match the basket to achieve consistent airflow and capacity on all models.
EVEN HEAT/GRAIN QUALITY: High/Low fire cycling helps to maintain a uniform plenum temperature.  14” wide columns hold the maximum
amount of grain while minimizing the difference from the inside to the
outside of the column. Each plenum chamber also has an air-mixing
chamber to thoroughly mix the air and heat and to shield the grain
columns from direct contact with the burner’s infrared waves. Multiple
heat zones in two-fan and larger model dryers put the hottest air on
the highest moisture grain.
LOW PROFILE, FOLD-UP WET BIN: The 14’6” low profile overall height
permits easy set-up into existing installations and allows the FFI dryer to
fit into locations other brands cannot.  The wet bin is perforated to enable
pre-heating of the grain, to increase capacity, and to reduce operating
costs. Maximizes pre-heating of grain at its highest point of moisture.
AIR MIXERS: Mixing vanes eliminate ”hot spots” and create a more uniform plenum temperature.
OPTIONAL ON/OFF FIRE: Offers a wider range of plenum temperature control down to 5 degrees above ambient for wheat and other temperature sensitive circumstances.
VISION CONTROLS: Globally compliant Vision controls offer more dryer performance information than any control in the industry. A large 10.4” touch-screen helps make this the easiest to use control on the market. Vision controls allow users to track the dryer’s history. All shut downs are logged with time and date information.
PATENTED GRAIN INVERTERS: To promote consistent, even drying, higher test weights, and a reduction of operating costs, be sure to add the FFI Grain Inverters option to your stack dryer package.  Be sure to maximize the efficiency of every FFI stack dryer by including the optional Grain Inverters.  While more traditional grain exchangers move grain
from the inside of the grain column to the outside of the column in 6” columns, the patented FFI Grain Inverters move all grain, except the outer two inches, within the column to eliminate over-dried grain and to maximize drying efficiency and grain quality. These patented Grain
Inverters redirect the warmest grain from the inside of the column to be next to the wettest grain at the outside of the column where it is dried by the captured heat which would have otherwise escaped the dryer. (See diagram to right for visual illustration.)  This process maintains optimal grain temperature, thus maximizing grain quality while using less fuel and significantly reducing operating costs.  A convenient clean-out door also provides easy access for quick maintenance.
AC METERING ROLL MOTOR WITH VFD: AC Metering Motor with Variable Frequency Drive (VFD) allows you to set unload speed without the need for time-consuming calibration. AC motors are considerably more durable and require limited maintenance.
8” DURA-EDGE®AUGER FLIGHTING: All augers feature the new DURA-EDGE® 8” diameter flighting with 1/4” ribbon. The DURA-EDGE®
flighting has an outside edge that is 30% thicker than regular flighting,
resulting in a longer life and increased dependability.
7” DIA. METERING ROLLS: Virtually eliminate material bridging over the metering system in heavy trash applications. The 7” diameter metering rolls unload more evenly over the entire width of the column making the need for grain column adjustments unnecessary.
REAR DISCHARGE AUTO-SHUTDOWN: A 2’ discharge extension with manual grain sampler is standard equipment.  An automatic discharge shutdown operates off of a hinged lid switch at the rear discharge. It is activated when grain overfills the discharge auger and forces the lid to open.
LARGEST GRAIN HOLDING CAPACITY: Allows for higher bushels per hour to consistently achieve maximum drying. Long retention times result in better grain quality.
IMPROVED LADDER DESIGN: Redesigned standard ladder package
for portable dryers to meet OSHA specifications. FFI ladders feature
heavy-duty construction and slip-resistant patterns to give extra grip
in wet conditions. Stacked dryers include platform.
CLEAN-OUT MADE EASY: Inside metering and unload auger access panels lift freely out of the way to accommodate service and maintenance. External cleanout doors positioned in each grain column offer quick and easy unloading of the dryer if needed. Also, an extra wide rear access door and 12” cleanout doors assists in seasonal clean out of the dryer.
THREE-PIECE SIDEWALL SCREENS: FFI’s three-piece sidewall panels
allow the top angle section alone, the top angle and side sections, or
all of the exterior screens including the bottom angle section to
optionally be stainless steel. This allows for economical protection
against rust and corrosion where needed, based on the size of dryer
and type of usage. All fastening hardware is also stainless steel to
eliminate future corrosion.
NOISE SUPPRESSOR: FFI’s standard low speed 1725 rpm blades make FFI axial fan dryers much quieter than in the past at a level that OSHA allows for continuous 6 hour exposure 15’ away. Though most situations do not require the Noise Suppression System those that want their dryer to be ultra quiet, even quieter than the competitive centrifugal fan models, the system will reduce the noise level at 15’ to one-fourth the OSHA 8 hour exposure limit. System can be integrated with Heat Reclaimer.
HEAT RECLAIMER: On multi-fan dryers, reduces the amount of heat lost when operating in Dry & Cool mode to the atmosphere and recycles it, thereby reducing fuel consumption and lowering operating costs by up to 30%. Open ductwork is optimally sized for 0% capacity loss as it prevents accumulation of fine material. Sized to reduce air velocity very little chaff or air debris is pulled into the dryer. Heat Reclaimer can be integrated with Noise Suppressor.
