Bühler empowers pulses processors to achieve consistency and quality through innovative product leadership

07/02/2014 Pulses processors benefit from over 150 years of Bühler’s expertise and experience to improve their productivity and yield. The Bühler Group, a global leader in food processing and optical sorting solutions, continues to underpin excellence in the treatment of pulses by offering cutting edge technology at every stage of the production process, from pre-cleaning, cleaning, grading, hulling, drying and splitting, through to optical sorting, polishing and final bulk packing, for the world’s vast array of pulse products. Specialising in turnkey as well as individual solutions, Bühler represents the perfect technology partner for pulse processors everywhere.

Much of the developing world relies on pulses, in order to obtain at least 10% of their daily energy intake and the demand for these invaluable products continues to increase. With this background, pulses processors are being challenged to produce ever more and ever better pulse products, reduce their wastage and improve quality and consistency – all within a smaller plant footprint. Rising to this challenge and drawing on more than 150 years of experience of processing food grains and seeds, Bühler’s technology supports pulse processors in their quest to drive quality, efficiency and profitability, and to compete in this vital sector of the global food supply chain.
Pulses, like any other grains, consist of starchy endosperms - a fat rich germ or embryo - and an outer hard protective layer, known as the husk or hull. However, unlike cereals such as rice and wheat, both the seed coat covering the grain and the underlying endosperm are firmly attached by a naturally occurring gum layer. The strength of this attachment varies with the differing types and the origins of the pulses, making them either easy or difficult to dehull.

Bühler’s dedicated pulse processing equipment has been developed to handle all types of pulses. The state-of-the-art technology overcomes the various adhesive forces within the grain, with minimum loss of the endosperm and produces the optimum in finished product yield and quality.

Each individual component of Bühler’s complete pulse processing line offering, such as Bühler’s Pulsroll AIHI, which gives exceptional hulling performance with minimum loss of cotyledon with skin, is designed to operate with lower energy consumption and easier, smoother operation.

For the drying of incoming raw materials, or for pulses at other stages in the intricate pulse production process, Bühler designed its Pulse Dryer, to give uniform and consistent drying performance. As a stand-alone piece of equipment or as part of Bühler’s turnkey solution, the Pulse Dryer consistently delivers efficiency, yield and final end-product quality.

As pulse quality is often defined by appearance and by the absence of foreign material, Bühler has perfected a range of equipment to support this. The Bühler Destoner ensures the removal of even the smallest of stones from incoming material, while the Bühler Gravomat Density Grader machine can be fed with 10 tons of product per hour and separate out 85% of the input into valuable grain. For the ultimate in peace of mind, the Bühler SORTEX optical sorting solutions remove even the most subtle light and dark colour defects, spots, damaged or blemished grains and foreign materials.

Each of Bühler’s modern pulse processing technologies ensure gentle processing, in combination with dramatic increases in yield, coupled with safety, ease of cleaning and handling, and seamless integration. The automation and sophistication they bring to the pulse production process help reduce damage, provide far more efficient separation of impurities and far greater recovery of valuable product, such as lighter grains, which would otherwise be rejected into the waste stream.

Automation and sophistication, in the integration of individual pieces of equipment, underpin Bühler’s turnkey pulse processing lines, which are now taking today’s pulse processors to new levels of productivity, consistency, safety and efficiency, not possible with individual pieces of machinery. State-of-the-art automation and control systems can help pulse manufacturers achieve a higher degree of process flexibility and a higher output than ever before. They also help to reduce processors’ dependency on labour and offer smoother operation.

Ultimately, understanding evolving customer and market requirements is a key factor and Bühler’s experience with these extends far beyond the pulse industry. Knowledge of the intricacies involved in each stage of handling processes, not only for pulses but for sesame, spices, rice and more, coupled with the versatility of solutions Bühler can offer, support a wide range of processors in their bid to increase yield and ensure a more profitable product, clean and free from foreign material, time and time again.
