A.O.M. preview: 100th technical conference and trade show

   A presentation on the history of flour milling highlights the Association of Operative Millers' 100th Annual Technical Conference and Trade Show May 4-8 in Minneapolis, Minnesota, U.S.

   In conjunction with the trade show, World Grain features the following products, services and developments of interest to millers and grain handlers:

      Agrogiva dryers and storage bins

   Agrogiva SRL, Milan, Italy, is known internationally for its efficient, top quality bins and storage plants. In 1995, the company introduced innovative developments in grain drying systems with the Ecodry, a new dryer that meets worldwide ecological and energy savings requirements.

   More than 3 million tonnes of grain and oleaginous seeds are stored in Agrogiva bins, and almost 5 million tonnes are processed and dried by the company's dryers. Agrogiva's highly qualified and experienced personnel meets the customer's needs by offering a number of services, including study and analysis of the project; layout, preliminary and final project design; project implementation; and commissioning, testing and staff training.

      Boston Gear motion control products

   Since 1877, Boston Gear, Quincy, Massachusetts, U.S., has led the growth in the power transmission industry with innovation and determination. Today, we have five manufacturing facilities in the United States whose completed products are inventoried at our central distribution facility supporting regional warehouses in the United States, Canada and Mexico. Boston Gear has a full line of electrical and mechanical motion control products to meet the industry's motion control requirements.

   The DuraKleen Boston Gear System is specifically engineered and designed for the flour milling industry. This U.S.-patented rollermill differential has proven to be reliable, and many millers have experienced reductions in unscheduled downtime and savings in related expenses.

   The DuraKleen Gear system, operating in the United States, Canada, Mexico and two European countries, uses the special Powerform tooth configuration to assure the dependability and integrity of the non-lubricated, non-metallic differential gear system.

      Buhler wheat tempering system

   Keeping informed about the latest developments in grain cleaning and processing is important to every miller, and the A.O.M. trade show provides ample opportunity to do so. Buhler Ltd., Uzwil, Switzerland and Buhler, Inc., Minneapolis, Minnesota, U.S., are exhibiting two of the latest designs, the MTRB Separator and the MYFB Automatic Moisture Control unit.

   Cereals need constant moisture to achieve the best milling performance with optimum flour yield and lowest energy consumption. The microwave technology is safe, and it accurately measures the moisture in either dry or damp grain.

   The new Automatic Moisture Control unit precisely calculates the quantity of water to inject into the MOZK Tri-Rotor Dampener, which is normally installed in the grain stream ahead of the moisture measuring unit. The intensive action of the machine forces the water to penetrate the wheat uniformly and quickly, producing the mellowing necessary for optimum milling. This newly developed solution allows a water addition of up to 7% in a single pass.

      Cimbria grain cleaners

   Delta, the cleaner division of Cimbria Unigrain A/S, Thisted, Denmark, is meeting the growing demand for larger cleaning machines with three new high volume cleaners. The new line, which includes units with capacities of 120 tonnes per hour, 240 tph and 360 tph, features the patented Drive Boss, a double drive balance oscillation and suspension system. Unlike traditional systems, the Drive Boss drives two sieve boats with only one eccentric drive. The eccentric rods are connected to the screen boats by special rubber oscillating drive heads, and the two screen boats are suspended by parallel double rubber swing elements. When one screen boat moves, the other swings in the opposite direction as a counterweight. This suspended swinging motion counterbalances the force of the screen boats, preventing the force from being absorbed by the cleaner frame and the building.

      Comptrol flow measurement, bag filling and palletizing

   Congratulations to the A.O.M. on its 100th anniversary — a century milestone to be celebrated! Comptrol has presented its products to the milling industry over the past 14 years, and we are very proud members of the A.O.M.

   At Comptrol, we make it our top priority to listen to our customers and develop products that meet their specific needs. The result — we are now the industry leader in supplying weighing and flow control solutions to the milling industry.

   Our products on display this year include the SUMamatic 36SLS, a larger model of the Feedamatic 67 Series of loss-in-weight scales and our new Momentum 25F Feeders. Also included will be the MillView, which offers critical data on mill and cleaning house operations; and the BlendView, which delivers an automated recipe base blending and mixing system. For the second year, Comptrol also will offer a complete line of bag filling and palletizing solutions.

   We will exhibit these products in booth numbers 21, 23 and 25 and invite you to stop by and discuss your needs.

      Fundiciones Balaguer chilled rolls

   Founded in 1916, Fundiciones Balaguer, S.A., Alicante, Spain, manufactures chilled rolls for the flour milling and oilseed industries. Solid rolls have uniform hardness because of casting of two materials that allow accurate measurement of chill depth. The rolls come in a range of standard hardness and can be modified at customer request.

      Grain Systems tower dryers

   Grain Systems, Inc., Assumption, Illinois, U.S., introduces a line of tower dryers for commercial grain operations.

   The dryers offer several features, including 30-centimeter grain columns equipped with grain turners to assure uniformly dried grain. A simplified grain discharge system eliminates sweep augers and provides for quick dryer cleanout. Recycled heat reduces fuel costs, and in line centrifugal blowers are internally mounted for a quiet operation.

   G.S.I. tower dryers also feature the new Electronic Monitoring Control System, which self-diagnoses dryer problems and displays the information on a large backlit liquid crystal display. The Electronic Monitoring Control System also is featured in new Airstream dryers introduced by G.S.I.'s Airstream grain conditioning division.
