Company TOMRA Food is TOMRA 3A - a sensory grading machine for freshly harvested root vegetables, able to offer potato growers unrivaled performance and functional reliability at an affordable price. Sorter TOMRA 3Atailored to the specific requirements of customers, outputs quality sorting potatoes to the next level with exceptional trash removal efficiency.
These sorting machines are usually installed at the entrance to the storage facility, where they carry out the final cleaning of the freshly harvested crop after it passes through a mechanical sorter and soil removal equipment. The machine scans and sorts incoming products on the fly, removing stones, soil clods and other impurities. Sorter TOMRA 3A capable efficiently handle large volumes, which fully meets the conditions of a short harvest season, as well as provide delicate sorting, which avoids causing damage to the product.
Jim Frost, Product Manager at TOMRA Food, says: “In developing this machine, we drew on extensive experience working with farmers in the industry, and also adapted our own advanced technological solutions that have proven themselves in our other devices. As a result, the new sorter gives farmers exactly what they need: more productivity, removal of green tubers, gentle product handling, increased operational reliability and excellent durability, ease of use and handling, more data collection and more detailed statistics, and a lower overall cost. possession ".
Advanced image processing technology and advanced automatic control functions
Advanced Image Sorter Processing System TOMRA 3A has the ability to identify colors, which makes it possible to identify unsuitable green potatoes. The use of semiconductor pulsed LED lighting technologies together with the use of high-resolution cameras allows the separation of root crops from foreign bodies. By analyzing a wide range of responses from multiple LEDs tuned to individual frequencies (some visible, some invisible infrared), advanced software detects the presence of herbaceous green potatoes that have become discolored by exposure to light. The sorter does not depend on the presence of external lighting and can work at any time of the day, be it day, evening or night, without reacting to changes in the light level.
During the operation of the sorter, moving parts do not interact, which increases the overall reliability of the equipment, and the hermetically sealed camera body is resistant to climatic factors such as rain, wind, dust and heat. Advanced technology TOMRA, in particular the automated alignment and calibration of the camera, guarantee the stable operation of the machine. In addition, the new thermal management system monitors the uninterrupted supply of optical signals, which ensures unrivaled performance in a stable and efficient operation in both cold early morning and midday heat.
Sorter TOMRA The 3A excels when it comes to tough short harvesting seasons and delivers increased - up to 30% higher - productivity. To meet the varying loading needs from enterprise to enterprise, the sorter is available with different feed conveyor widths: 120 cm, 160 cm and 240 cm, which allows processing up to 45, 65 and 100 tons of root crops per hour, respectively.
Sorting plant TOMRA 3A employs an ejector pin system across the entire width of the sorting space. Mechanical ejector pins are designed to maintain operational reliability and efficiency when removing even the largest and heaviest potatoes from the line, thereby minimizing the need for repair or replacement parts. Optimized pin movements prevent adjacent root crops from banging against each other when entering the sorted product area. Delicate handling of potatoes is a key advantage of sorters TOMRA... The “selected products” conveyor has a unique design, thanks to which it grips, slows down and delivers high-quality sorted tubers without damage or dents.
Sorter TOMRA 3A is controlled by platform based software TOMRA ACT, a multi-award winning company. The graphical user interface, as well as various functional solutions, are borrowed from the "big brother" - the sorter The TOMRA 5A ... For ease of use, a wide 15-inch touchscreen with high resolution and increased brightness is used. Interface TOMRA The 3A offers the following functions: alarm, statistics and diagnostic capabilities with the option of remote support via a 4G modem connection.
The machine is easy and convenient to operate. Easy access to the ejector mechanism allows customers to order and replace parts themselves. The new LEDs are designed for long life and do not need to be replaced annually. The use of modern sensor technologies allowed the cameras to be placed as far away from the product sorting area as possible, which significantly reduced the need for cleaning equipment and maximized the continuous operation of the sorting machine. This way, the potatoes get into storage faster.
In addition, storage space is used more efficiently, since trash and poor quality tubers are kept out. Among other things, the farmer can provide the client with the highest quality product - in full accordance with the approved specifications.
Jim Frost commented on the market launch of the new screening plant as follows: “Real field trials TOMRA 3A with the sorting of freshly harvested potatoes and already processed tubers, carried out in cooperation with farmers in Ireland and France, confirmed the high reliability and production efficiency of the machine. All farmers who tested TOMRA 3A, expressed a desire to purchase it! We expect that TOMRA The 3A will be very popular with potato growers and root cannabis packaging shops around the world. ” Sorting plant TOMRA The 3A was first presented on 4 and 5 September at the International Potato Show in Tournai (Cain), Belgium.
