The OPI Integris Grain Management system goes way beyond the moisture-tester-run-the fan approach to grain moisture management of previous technologies. In fact, this technology manages not only grain moisture levels, but grain bin temperature and insect infestations as well. When Skyway designs a grain bin drying system, this is the moisture management system that we use.

The OPI Integris system utilizes crop data they have experimentally developed to direct the moisture management of barley, canola, corn, oats, popcorn, rice, sorghum, soybeans, sunflower and wheat. Each of these commodities exhibits specific characteristics in terms of their uptake and shedding of moisture. These characteristics are built in to the OPI-integris system which directs the control of fans and heaters to achieve optimum moisture levels when it comes time to market the grain.

The OPI Integris system saves money in two ways: by ensuring optimum moisture levels and minimizing shrinkage in grain at shipping time, and by achieving this optimum level by directing the use of fans and heaters at times when conditions are ideal to add or shed moisture.

The system works like this.

OPI Integris has several levels of grain management systems. The most basic level involves temperature monitoring cables in each grain bin. The number of temperature monitoring cables varies with the size of the bin but for illustration purposes, let us use a 48’ bin. A 48’ grain bin requires 6 temperature monitoring cables. One cable in the centre of the bin, and the remaining 5 cables distributed evenly around the perimeter of the bin.

The retractable temperature cables are encased in a protective sleeve and feature a sensor at 4’ intervals along the cable. The temperature data collected by these sensors is downloaded to a handheld monitor and displayed 32 sensors at a time on the monitor screen.

The second level of the grain management system includes cables to monitor moisture levels in the grain. Again, the cables are housed within a protective sleeve and feature sensors at 4’ intervals. These sensors collect data on the relative humidity of the air around the grain. In a 48’ bin, the centre cable would be a moisture cable and 2 of the five remaining cables would measure moisture. Again the readings supplied by the cables are collected by a handheld monitor and the data is shown onscreen, 32 sensors at a time.

The third level of the grain management system is where the system actually manages the quality of the grain in the bin. This system is either wired directly into computer software or is transmitted wirelessly to the software. Moisture is added or eliminated from grain in the bin through the judicious use of circulation fans and heaters. If the grain needs to have moisture removed then the system activates the fans and heaters when the relative humidity around the grain bin will allow the air blowing through the grain to pick up moisture from the grain and eliminate it through the vents.

If the grain is over dry and needs moisture added to the bin, the fans are activated when the relative humidity around the bin will allow the air blown through the brain to add moisture to the grain in the bin. All of this happens automatically and is driven by the software developed after extensive research on which crops require which treatment regime to accomplish optimum moisture content for the seed in question.
