| Increase Agricultural Productivity by Adding a Bulk Feed Bin System |
Bulk feed storage bins are used for safe, dry feed storage. Bulk feed bins protect feed from the negative effects of weather. Ideally, they are made from corrugated sheets of galvanized steel as grain stored in plastic bins will rot. Bulk feed bins are typically used to supply poultry houses, pig houses, horse barns and dairy barns. They will increase productivity in a poultry or livestock operation through the increased ability to monitor the feed intake of each animal or group.
Bulk feed tanks are designed for the storage of material having a density of no more than 40 pounds per cubic foot. This style of feed bin is designed for the storage of free-flowing material only. Soybean meal, meat scraps, and certain other materials are not considered to be free-flowing and should not be stored in these bins.
All farm bins must be periodically replaced as they can collapse or split during filling. Dents at the base that weaken the structure are caused by vehicles or owners that attempt to free up the grain flow by hitting the lower part of the bin with a heavy object. Dents can put strain on welded seams or joins. Common visual cues to structural deterioration that indicate your bin may need replacement include bowing panels, deformed legs or joints, and corroded bars or bolts.

| Standard features in a bulk feed bin system
|
|
Bulk Feed Bin Panels for the desired size or capacity - 6 ft., 7ft., 9 ft. diameter etc. The number of corrugated rings determines how tall your bin will be. 4" wide corrugation reduces the resistance to the downward flow of feed, feed hang-up and bridging. Industry test have proven that wide corrugation gives 25% more vertical strength than narrow corrugation, and almost twice the strength of bins with no corrugation. Wider corrugation results in wider bin sheets, thereby increasing capacity making the same width corrugated bin hold more bushels than a narrow corrugated bin.

|
Hopper - Hoppers come in several degrees of slope to facilitate the smooth flow of feed. Tank hoppers are available in three slopes: 45° for dry, free flowing grains; and 60° or 67° for harder flowing materials. A hopper access door will permit easy clean out of the bin from the ground.
|
|
Hopper Stiffener - A hopper stiffener is considered mandatory if the bin size is 7 ft wide x 5 rows high or greater. A hopper stiffener is optional if the bin is smaller but highly recommended if using soybean meal, high fat feeds, heavy feeds or non non-free flowing materials in any size bin.
|
|
Lid - the lid must be easy to operate, operate from the ground so no one has to climb up to the top when the feed truck comes to deliver, and seal the top from the wind, rain and snow.
|
|
Roof - A 40-degree roof pitch will match the natural incline angle of stored feed to maximize the usable storage capacity of the bin.
|
|
Side and Roof Ladders - While ladders are often sold as an option, they are highly recommended. Falls are one of the most common farm injuries. A fixed ladder is necessary for the safe operation of a grain storage system.
|
Unloading System (Slide Valves, Poly Boots & Unloaders) - Some kind of unloading system is a necessary part of the total bulk bin system to get the feed out of the bin.
A hopper valve is used for wheelbarrow unloading. Raise the handle and a gate on the side of the bin/ hopper slides open and releases feed down a chute to your bucket or cart. A hopper valve and slide valve may both be installed at same time.
Boots are for automated feed delivery systems using augers to provide an even flow of grain. If using a poly boot and unloader, the poly boot must match the auger diameter.
|
Augers - An auger is an optional part of the grain storage system. They are used to automatically and efficiently deliver feed from the bin to the livestock. Using an auger system to automate the delivery of feed saves a significant amount of manual labor - no hauling feed in wheelbarrows or buckets. Most auger systems offer a choice of feed conveying rates. Augers come in different diameters depending on the desired volume for delivery as well.
A fixed auger is for outside operations. An adjustable auger is for "through the wall into-a-building" applications. Note that the auger diameter must match the poly boot size on the bottom of the hopper. A motor and V-belt is required if an auger system is selected. A pulley is also required with an auger and motor.
|
|
Auger Bracing - While optional, an auger bracing kit is highly recommended for safety and wind protection with a free standing auger.
|
Motor - Select a motor if an auger will be included in the system.
Example:
4" Auger - 5 hp motor
6" Auger, 1.5 or 2 hp motor
Larger hp for high fat or heavy feed
|
Pulley - Select a pulley if an auger will be used.
2.5" pulley for 4" Auger
3.6" pulley for 6" Auger
|
V-Belt - Select one if a motor is selected.
36" for 4" Auger
48" for 6" Auger
|
|
Scales - Digital scales give highly accurate weights for feed stored in individual grain bins. The bin sits on weight bars providing information such as how much feed was consumed yesterday, today or total consumption.
|
|
Sensors - An electronic system of sensors and software for inventory management can be added to a bin for even further automation. Sensors measure feed level in the bins, trigger low feed level alarms, and measure feed disappearance and consumption over time for specific groups of animals while software uses re-order points to forecast when the bin will be empty and assists in scheduling feed deliveries.
