An in-depth look at equipment for efficient grain handling and storage
Agromatic AG, Laupen, Switzerland, the leading manufacturer of measuring and control systems for mills, feed mills and silos, looks back on a very successful past.
Since the company's founding in 1979, Agromatic has become the largest producer of silo temperature measuring systems. Approximately 3 million tonnes of silo space are equipped with Agromatic measuring systems every year. Agromatic systems offer the highest levels of safety; they continuously measure and give alarms 24 hours a day.
Dampening systems by Agromatic (Agrogran N) are known worldwide in the milling industry. They are produced with capacities ranging from 3 tonnes per hour up to 200 tph (for dampening in a silo). Agromatic also produces all types of full and empty level indicators, including capacitive (self-adjusting), mechanical (rotary flaps) and vibrating rods. For continuous measuring of silo levels, units are offered for bin heights of up to 60 meters (ultrasonic version).
Agromatic provides metal detectors and separators for all applications. Whether the safety control point is in the ready-made packed product, in the loose loading or in the manufacturing process, Agromatic offers the right machine for the specific purpose.
In some countries, rotary speed- and alignment monitors are a must. Agromatic produces a wide range of combined units (one unit for rotary speed- and alignment control). Wherever safety in the elevator is necessary, Agromatic's series ALS197 units are in use.
Grain cooling equipment without programmable logic control is still on the market today. Agromatic's “Coolstop,” which incorporates silo temperature measurement in connection with a grain cooling machine control, allows the optimum control of the cooling equipment and consequently prevents the waste of energy.
Behlen Mfg. Co., Columbus, Nebraska, U.S., is a supplier of steel bins up to 18,230 tonnes (31.85 meters in diameter) and hopper bins up to 1,000 tonnes; as well as “Berico” commercial dryers of grain, oilseeds or rice in capacities up to 136 tonnes per hour. Behlen bins utilize a trapezoidal wall panel design for added strength.
Behlen/Berico dryers are noted for energy efficiency with a hot air recirculation system and trouble-free performance. Grain enters the dryer through the grain intake located on top of the unit. How quickly the grain passes through the dryer depends on the moisture level of the end product.
From the intake, the grain moves into the receiving hopper and then to two narrow vertical columns. High air flow within the columns produces fast surface-moisture removal. As the grain drops deeper into the dryer, the columns expand out in width. This extra width allows for gentle, internal kernel moisture removal and maximum cooling time in the cooling section.
As the grain reaches the mid-point of the dryer section column, grain moves from one side of the column to the other. This “Turn Flow” process takes the grain that was on the inside of the column and exchanges it with the grain on the outside of the column.
This mixing action delivers uniformly dried grain and minimizes grain kernel temperatures for better quality. These dryers are available in a wide range of capacities for use in drying a variety of grains.
Behlen also manufactures a wide range of flat storage buildings, including a full line of commercial/industrial building systems. Behlen's design capabilities combine with manufacturing expertise to assure quality leading products.
Behlen, with more than 60 years of experience, is a worldwide supplier of products in use in more than 50 countries. The global need for technology and products continues to grow, resulting in an important market for Behlen Mfg. Co.
A new generation pneumatic shipun-loader for grain and feed derivatives is now available from BMH Marine, Bjuv, Sweden. It can be supplied in various sizes with unloading capacities of up to 400 tonnes per hour.
The extensive know-how in pneumatic transportation of various types of bulk materials within the BMH group of companies has been utilized in the development of the new machine.
The unit structure has been designed with the aid of the latest computerized design technology, resulting in a light, yet sturdy construction.

Currently, 25 satellite facilities are under construction with 25 more scheduled for construction. These facilities, like the one pictured in Khas Alez, Syria, supply wheat to a regional elevator and then to a port facility for exporting.
The proper design of grain handling and storage facilities is going through significant changes, as new and increasing demands are being brought to the grain sector. Kepler Weber, Porto Alegre, Brazil, leader in the South American market for grain storage facilities, is keeping pace with this evolution through the development of equipment that allows cleaning, handling, drying and storage at lower rates of product loss, with savings in fuel and energy and respect for the environment.
As a result of the evolving environment, the capacity and flexibility of grain handling facilities can be quite demanding as evidenced by extra high moisture-content grain coming into the plant, extra-short harvesting periods, several simultaneous crops or varieties or even the combination of these possibilities.
Grain quality preservation, which requires a proper conveyor design that causes little or no damage to the product, and dryers, with a gentle drying process by means of adequate moisture removal rates and an even treatment to all kernels, are also important features.
To achieve these features, the key parameters are: suitable conveyance speed and restrictions to grain falls; and for the dryers, large static capacity, proper drying air temperature and preferably mixed-flow type dryer bodies. Last but not least, it has to be mentioned that cleaning is of major importance, given that processing equipment works better with a clean product, no matter if it is a conveyor, a dryer or a bin.
Once the grains are cleaned and dried, new challenges are expected for the storage procedures. The new requirements for pest control and the suitability of the equipment for the so-called “integrated pest management” have been widely discussed in recent years.
To satisfy these requirements, new developments are in the pipeline to provide equipment with proper sanitation and sealing features. Even more demanding characteristics are expected to be incorporated into grain equipment, with the banning and phasing-out of several currently used pesticides that are in progress because of agreed protocols. No doubt, significant innovations will result as a consequence of this fact.
