Effective grain cleaning is only possible once you determine your needs and following that up with a comprehensive, tailored cleaning system to achieve the desired specifications.
It is often said that grain quality can never improve after it's been harvested. No matter how well an elevator dries their grain, monitors its bin temperature, manages moisture and controls pests, not much can be done to bring the quality up a notch once it's taken from the plant. For the most part, this notion holds true with the exception of one measure: grain cleaning. Taking this step right after harvesting can get the whole process off to a smooth start. While grain cleaning doesn't physically add anything to the grain, it certainly adds value by removing foreign materials, making it a more marketable product.
Clean grain is achieved through a variety of products such as screens, vibrators, scalpers and aspirators. Grain passes over screens while different sized holes allow unwanted pieces to fall through, leaving only the desired size or shape grain behind. Also, grain is screened to remove oversized and foreign materials. Elevator operators determine how much foreign matter, or dockage, to remove based on specifications handed down from their customers or the Federal Grain Inspection Service. These specifications depend on the type of grain and its intended destination.
According to experts in the cleaning field, the dockage is the most important player in the grain cleaning game. Knowing the desired specifications is a good starting point, but developing the best cleaning approach to achieve those specs depend on what you need to remove from the incoming product.
Dockage refers to several types of foreign materials such as straw, chaffs, hulls, seeds, dust, sand, pests and damaged or immature kernels. The FGIS puts strict standards on how much of this material can be present within the crop. The website has published the official U.S. standards for all grains, such as corn, barley, wheat, soybeans and sorghum, among others.
The FGIS defines dockage differently for each grain. According to the FGIS website, corn dockage is-
Grain, feed and seed facilities are often faced with a dirty situation when designing dust collection for rail car and truck dump pits. Designing a dump pit with good dust collection in mind not only addresses the dirty situation, but can save you operational time and money.
Point-of-use dust collectors capture nuisance dust while keeping product with the grain stream.
We’ve all seen the headlines across social media about the potential for Cuban Cigars to be legalized. That’s because in December 2014, President Obama said the U.S. would soon re-establish relations with Cuba nearly 55 years after the trade embargo was enacted
Industrial facilities that use rail as a part of their operation move railcars by a variety of motive power types. No matter what type of motive power is used, applicable rail operating safety rules and procedures should be followed. Applying up-to-date rules and procedures to rail operations will enhance employee safety and facility efficiencies.
Having automated technology running operations in facilities has been an industry standard in the feed industry for years, and the grain industry is rapidly catching up. The advantages of the technology are numerous and evolving. Automation improves equipment life expectancy, employee safety and productivity, facility efficiency and ultimately profitability.
Feed & Grain is proud to announce the winners of its 2014 Harvest Photo Contest. Entries poured in from December 2014 until this February showcasing our readers’ ability to manage a record crop — some with limited access to rail or other shipping options. Congratulations to all the winners and honorable mentions!
The year 2014 ended as a mixed bag on the transportation front. Historically poor railroad performance in the Northern Plains and record-high costs for railcars were detrimental to many grain shippers. But on the bright side, Congress’ passage of the Waterways Resources Reform and Development Act recognized the importance of maintaining vital waterways like the Mississippi River.
In comparison to many transactions in the business world, grain and feed ingredient purchase and sale transactions are fairly informal. In many respects, grain and ingredient trades remain relatively straightforward and largely result from casual telephone conversations followed by a short written confirmation.
