  3. 3. P reserving grain weight and quality whilst prevent- ing insect infestation, mold presence and therefore avoiding dangerous toxins. The grain cooling techniques were developed by scientists originally with the target of temporary keeping the grain safe with higher moisture contents till their drying process, thus managing larger amounts of grain with existing driers. Later on, the grain cooling showed many more advantages. Wheat and corn were the targeted products at the beginning. Having never been done before with paddy rice, Consergra lead this first ever practical test with paddy -and later with oth- ers- which took place at two rice co-operatives along the Ebro river delta in Spain. After some very successful results coming out of this research Consergra have led the way in chilling rice in bulk. Through the 70’s, 80’s, 90’s and noughties chilling rice has become a more and more common procedure. Consergra have constantly kept innovating and it is this, which keeps them ahead of the field in grain chilling technology. Talking with the Managing Director for Consergra Joan Rius, our International Marketing Manager Darren Parris learns what Joan, feels separates Consergra from the competition. “For over 45 years we have researched and developed grain cooling technology, specializing in the chilled bulk preservation of all kinds of grains, seeds, oilseeds, and many other perishable products” Joan went on to say, “Our product Conserfrio® is a registered brand of the Consergra company, which stands for CONSERving GRAins”. Our experience includes the conservation of wheat, barley, corn, oats, paddy rice, milled rice, …, soybeans, sunflower seed, rapseed, cotton seed, …, green coffee beans, ead- ible beans, different kind of pellets, nuts and many other perishable products. Continuing on from the early works with paddy rice, more recent tests with cargo and milled rice, in all varieties of long, semi-long and short grain have all showed the very same successful results as their counterparts back in the beginning. It is because of this research you will see that many different types of rice and grains are preserved using the Conserfrio® product. Many hundreds of these units are now being used in countries all over the world. Consergra was estabilished near to Barcelona, Spain many years ago and since then, one of its key activities has been in the design and manufacturing of cooling machines which are mainly used for the grain conservation. Joan Rius, further explained “besides the rationally scaled standard grain cooler production program, which covers capacities starting from 30 up to 500 tons per day, per machine, we build customized solutions for special projects where solutions are tailor made for process control applications in seeds, food, feed and other industries where a strict control of air and temperature, moisture and flow is needed. “ On asking Joan what sets Consergra apart from the competi- tion, what USP’s do you have; Joan replied “ All our Conserfrio® CONSERVING GRAINS Case study 1: Capital Cereals Company Capital Cereals Company (CCC), located near to Bangkok, is a Thai leading company in the process and reprocess of white (also called milled) rice. The current total storage capacity at just this plant alone (CCC currently owns other plants in different locations s as well) is 450.000 tons approximately. As a leading Thai company they have high expectations to match their very own impres- sive and highly technologically advanced plant. Being such a large state of the art plant the white rice is stored in concrete silos as well as in huge warehouses. The white rice is stored for up to one year at a time. So it is clear with such high capacities and production, they needed a quality solution to keep their rice cool. In the concrete silos there is a ducting system at their bottom. The chillers are placed under the silos. At the warehouses, a combination of both on-floor ducting system and under-floor ducting system is used. On-floor for the older ware- houses, under-floor at the new- est warehouses, which were just built one year ago with the latest storage expansion program. The clean, temperature and humidity controlled air blown by the Conserfrio® chillers is drawn into the grain mass cooling the entire product when crossing the pile. Using this method, the prod- uct keeps its original white color without getting yellowish or damaged by insects. The freshness and the best flavor of the CCC product are kept at their very best right up until the dispatching date, which can be a year after storage commences. CCC purchased the first CONSERFRIO® units many years ago, and installed more units recently as the storing capacity increased with the new built warehouses. On operations of this scale, the cost of purchasing and the efficiency of running the cool- ers can be recouped in product saving within 12 months to 18 months. Joan added; “Currently 18 Conserfrio® units of different types help our customer in his task of having the best product by preserving the quality of the milled rice, avoiding product color dete- rioration (grain yellowing), aroma loss, insect infestation and all related issues to grain storage” through drying 36 | March - April 2014 GRAIN&FEED MILLING TECHNOLOGYF

In addition to this we are very proud at Consergra to have the ISO 9001-2008 (TÜV certified) where we are certified for the design and manufacturing of industrial and agricultural machinery”. and the experience we gained throughout all these years and accurate after sales service are key. Looking through the global list of Consergra custom- ers, it is clear to see that Conserfrio® units are installed all over the world. They are being used more and more in mild weather countries, but especially in those areas where the ambient heat and moisture damage the grains quicker. Joan Rius added, “With cooling, optimal grain con- servation is achieved which often minimizes and even completely avoids the use of chemicals. Besides being a cost-effective operation, the grain weight and quality is preserved at its best avoiding weight losses, insect infestation, mold presence and therefore the so dangerous toxins. The optimum product moisture content is kept as well. “ More than 15 years ago, the Conserfrio® chiller was introduced into Thailand and since then more than a hundred units have been set up and are in operation in this country alone. Some Thai customers owing their continued growth and success over the last decade to the excellent experience that have had with the Consergra chillers. In Thailand the coolers conserve mainly rice (paddy and milled) and corn, including their seeds as well. Below you will find two brief reports on where coolers were successfully introduced in two leading Thai companies for different applications of both paddy and white (milled) rice cooling in bulk in silos as well as in warehouses. Case study 2: Tonghua Rice Tonghua Rice is another Thai leading company in the Jasmine rice process and trade, their rice is exported all over the world where highest quality is demanded. Tonghua Rice is located in the Bua Yai District, Nakornrachasima, North Eastern area of Thailand where the jasmine rice is grown. At this huge and highly techno- logical facility of Tonghua Rice their activities include drying, storing, milling, packaging of most delicate jasmine rice. Their current installed storage capacity is approx. 150.000 tons, which is divided into several large ware- houses. The rice is safely stored for many months. At the Tonghua Rice company, 24 Conserfrio® units keep the excellent quality of their jasmine rice. Not only are the paddy rice cooled, some chill- ers are also used to keep the white rice packed in a cold room before the rice is dispatched. The unique design of the cooling units permits high flexibility in their use without any modification. This process of chilling allows the Tonghua rice company to maintain its high quality and demand good prices for its products.
