Portable Grain Dryers

When drying capacities exceed the ability of a standard in-bin dryer, you can depend on FFI Portable Dryer lineup to fulfill practically an on-farm drying need. Because every dryer they produce is thoroughly tested throughout the manufacturing process, you can be sure that when it's time for on-farm installation, your dryer will be up and running quickly and efficiently.

Whether you grow corn, soybeans, or small grains, FFI single, double, or triple module Portable Dryers allow you to start harvesting your grain earlier at higher moisture levels, increasing yields and improving profits. You'll shorten wait time during drying, minimize weather risks, and reduce dry matter and head shatter loss.

FFI Portable Dryers are designed to provide the capacity you need in a footprint your layout can handle. The single module models can be upgraded to 1,160 BPH at 5-point removal All Heat without changing the layout of the load or discharge equipment. Our stack models can be upgraded to 2,450 BPH at 5-point removal Dry & Cool or 4,000 BPH All Heat (with limited colling bin size and special management) without changing the footprint or concrete foundation. And because they are scalable, you can begin with a simple system that moves grain by an auger or a more advanced system that incorporates an overhead wet bin, drag conveyors and bucket elevators.

The Inverter Advantage

Moving Grain for Consistent, Even Drying

To promote even, consistent drying, higher test weights, and to reduce operating costs, add a patented Grain Inverter option to your stack dryer package.

How It Works

The Grain Inverter redirects 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.

By inverting all but outside two inches of grain from the outside of the grain column to the inside, this process maintains optimal grain temperature and maximizes grain quality while using less fuel and significantly reducing operating costs.

In addition, the convenient clean-out door makes maintenance quick and easy.

Metering Rolls with VFD

Proven, Consistent Unload

Metering rolls with AC Variable Frequency Drive (VFD) provide a gentle flow of grain to the auger. The AC Metering Motor with VFD allows you to set unload speeds without the need for time-consuming calibration. AC motors are considerably more durable and require limited maintenance.

Standard 7" diameter metering rolls unload more evenly over the entire width of the column, making the need for grain column adjustments unnecessary. This proven design allows material to flow easily, resulting in a smooth transition from your dryer to your handling system.


Portable Grain Dryer Features

Static Moisture Sampler

Take your moisture sample accuracy to a new level with the Static Moisture Sampler. Featuring debris guards to ensure a trash-free, accurate sample, our sampler takes readings only when the grain is static and not flowing. Using FFI's patented discharge auger to ensure that a true cross section of the grain is sampled, a reading is taken once per minute. Based on more accurate moisture readings, your dryer adjusts to provide optimal results. FFI's sampling innovation moves the grain with air, not with gear boxes, pulleys, belts, or other conventional moving parts. The sampling chamber is blown empty, completely cleaning it after every cycle.


High Efficiency Burners

Efficiency Burner.png

Wherever you farm, whatever the weather conditions, FFI's high-efficiency burners are proven to provide even heat and deliver maximum airflow to the dryer's plenum. Single module dryers are equipped with high-quality ASCO valves. MAXON gate valves are the primary main gas supply valves on stackable dryers. An electronic ignition system monitors the burner, and a view window provides easy observation of the burner while in operation. Features include, easy-to-adjust vaporizer, large service access door and oil-filled gas pressure gauges.

Exclusive On/Off Fire

Only available and standard on GSI and FFI dryers, On/Off Fire offers a wider range of plenum temperature control, down to five degrees above ambient temperature, for wheat and other temperature-sensitive grains.

Largest Grain Holding Capacity

Apply excessive heat and you compromise grain quality. Larger grain column holding makes achieving rated drying capacity more likely. Drying grain too fast or too slow with the wrong air flow results in low quality grain and/or decreased efficiency. FFI dryers provide the optimal balance between the heat level, retention time and airflow for best grain quality and efficiency.

Even Heat & Grain Quality

High/Low Fire cycling helps maintain a uniform plenum temperature. the 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 infrared damage. Multiple heat zones in two-fan and larger model dryers put the hottest air on the highest moisture grain where a grain inverter is not installed.

Optimized Airflow

In all dryer models the airflow is sized to match the basket to achieve consistent airflow and capacity.

Even Heat & Grain Quality

More efficient than centrifugal fans, axial fans with composite polymer blades allow for a very low starting load which extends motor life and requires no rebalancing during the life of the dryer.

Additional benefits include high air flow across a wide static pressure range, quiet operation and reduced energy cost.

Stacked dryers include platform(s) on the upper modules with optional platforms for the bottom module as well as the top and side service platforms.

X-Stream Dryers

Maximum Efficiency, Unsurpassed Quality

Fans and heaters on most traditional dryers are mounted on the same end of the dryer. The optional X-Stream dryer design features fans and heaters mounted in a staggered configuration on opposite ends of the dryer. With this design, the X-Stream delivers more uniform heat throughout the entire dryer, regardless of column location. The result is a higher quality grain that is more evenly dried at a lower cost and up to a 10% grain in efficiency.

Unparalleled Performance

For even greater performance and the highest efficiency possible, add the optional grain inverters. Combined, the grain inverters and the X-Stream stack dryer dry again evenly from the front to back and across the entire column without the loss of usable heat. This combination of exclusive features gives you the most efficient portable dryer on the market.
