Introduction to high moisture grain storage in silo bags

High moisture grains are a quality, economical feed source that eliminates the high cost of drying. Rather than organizing a substitute feeding system, using high moisture grain involves a change in harvest schedules and storage methods. By processing the grain into storage, better efficiency is achieved by eliminating processing at the time of feeding. Corn is the principal grain harvested and stored in high moisture form but sorghum, wheat, barley and others are equally suitable.

It is important to notice that some of the main objections often cited against high moisture grain can be disregarded when silo bags are used. Indeed, these objections point at the fact that with conventional storage large expensive facilities are needed, that storage losses are large through exposure to air, and that these losses increase and persist whenever ensiled grain is removed at feeding time. Bags do away with these problems.

High moisture grain production has a number of agronomic and economic advantages. These include: a harvest date several weeks in advance of harvest for dry storage, which contributes to a 3% to 6% decrease in field and harvest grain losses; elimination of drying costs; also a reduced commodity cost that has to do with seasonal grain prices and discounts equivalent to drying and elevator dockage charges.

With the Richiger processing system, grain can be rolled or ground with mills mounted atop the baggers and then packed inside the bags, all in one single movement. With corn, if the bagger used is model R6MFA equipped with a hammer mill unit, both shelled corn and ear corn can be ground and stored in the form of high moisture corn (HMC). Of course dry corn and other dry grains can also be ground and stored in the same way as moist produce.

Richiger also has several bagger models equipped with roller mills, namely models R650M, R650MX, R950M and R950MX. These roller mills can produce approximately 40 metric tons per hour, and are mounted on 6 ft. and 9 ft. baggers as either single or twin mill units. In the latter instance production rate is 80 tons of crimped (or rolled) grain per hour. For added marketing flexibility, all Richiger baggers can be used for bagging unprocessed dry grain as well.
