WELCOME TO BÜTTNER DRYING TECHNOLOGY, BURNERS AND ENERGY SYSTEMS FOR THE GLOBAL MARKET Since its foundation by August Büttner in 1874 in Krefeld, BÜTTNER Energie- und Trocknungstechnik GmbH has looked back on a remarkable long tradition. Today BÜTTNER is the leading international supplier of complete plants in the field of heat generation and drying technology. BÜTTNER assumes responsibility for engineering, supply and installation as well as the commissioning and after-sales service of plants for industrial clients around the world at the highest technical level. Quality, reliability and efficiency...

EXPERTS IN ENERGY AND DRYING

APPLICATIONS The different dryer systems, the range of burners and the BÜTTNER energy systems are always used with the aim of drying industrial goods or providing process heat. MDF boards from wood fibres, OSB boards from strands or particle boards are just three examples from the wood processing industry of where BÜTTNER systems are used. The fibres for wood fibre insulation boards used in home construction as well as the flakes for the increasingly popular wood pellets also first have to go through an industrial drying process. Outside of the pure wood industry, bulk solids, animal feed from...

WOOD FIBRES FOR MDF AND INSULATION BOARD DRIED EFFICIENTLY IN BÜTTNER FLASH TUBE DRYERS A preferred material for furniture, flooring or ceiling panelling: medium-density fibreboards (MDF) are in use around the world. Their quality depends on proper production. BÜTTNER supplies the wood-based panels industry with energy systems, drying systems and burners, which ensure that wood fibres are quickly and efficiently dried, before they are pressed. Medium-density fibreboards (MDF) and high-density fibreboards (HDF) are made of wood fibres and characterised by their particularly homogeneous structure....

DRYING OSB STRANDS WITH BÜTTNER SINGLE-PASS DRUM DRYERS Once called wafer boards, everyone has heard of the OSB boards used in construction and packaging; long, thin flakes (strands) from debarked logs are layered and then pressed into large boards. The wood-based panel industry's modern, highly-efficient presses require a source material which exhibits a permanent uniform degree of moisture. The flue gas required for heating the dryer is generated either in the grate firing system or in special combustion chambers with multi-fuel burners. Manufacturing wastes, for example bark, screening and...

BIOMASS FOR ENERGY RECOVERY BÜTTNER DRYING SYSTEMS AND ENERGY SYSTEMS, A COMBINED SOLUTION The utilisation of renewable raw materials is attracting ever more attention and the application of biomass as a fuel is now commonplace. Bark, waste from the wood industry, from roadside maintenance and from landscaping, as well as agricultural waste such as straw or palm fibres serve as fuel. Although the composition of biomass is extremely heterogeneous, all materials have one thing in common: in most cases their water content must be significantly reduced before they can be used for energy. BÜTTNER’S...

WOOD FLAKES FOR PARTICLE BOARDS HIGH QUALITY STANDARDS THANKS TO BÜTTNER FLASH TUBE PRE-DRYERS AND DRUM DRYERS Particle boards have a special place among wood-based materials. They were traditionally, and are still to this day, used to a great extent in furniture production. Chipped waste wood, wood thinnings and recovered wood are the raw materials used to produce particle boards in the wood industry. For particle board production, wood flakes are glued, sorted according to size and then pressed; the larger flakes form the middle layer and fine flakes the hard surface. A uniform moisture level...

FLAKES FOR THE PRODUCTION OF WOOD PELLETS FUEL PRODUCTION WITH BÜTTNER ENERGY SYSTEMS AND SINGLE-PASS DRUM DRYERS Wood pellets are popular as fuel for private homes and industrial firing systems. The rod-like pellets are produced mainly out of wood wastes from saw and planing mills, as well as from debarked and shredded logs. BÜTTNER'S drying systems ensure that wood chips are dried efficiently with energy savings in mind and at the required moisture level before they are made into pellets. Both small and large flakes must have a constant level of moisture before being pressed into the ring die...

DRYING OF BULK SOLIDS SINGLE-PASS DRUM DRYERS AND OTHER DRYING SYSTEMS FOR FREE-FLOWING MATERIALS Free-flowing bulk solids represent very different challenges to the drying process because of their heterogeneous nature. Wood particles, beet pulp and other biomass products are processed differently from fertiliser, soil, fodder or coal. Based on decades of experience with a variety of materials, BÜTTNER has established a comprehensive spectrum of drying solutions and related thermal energy systems. In addition to a customised drying process for bulk solids, with single-pass drum dryers or tube...

SUGAR BEET PULP FOR PRODUCTION OF FODDER ANIMAL FODDER FROM SUGAR PRODUCTION – DRIED WITH BÜTTNER'S DRYING SYSTEMS In Central Europe sugar is generally produced from sugar beet, and in the tropics from sugar cane. After waste materials are dried and made into pellets they serve as energy-rich animal fodder. To this end, BÜTTNER supplies flexible drying and energy systems, which together ensure that the dried pulp has a homogeneous moisture distribution. This is the only way that pellet presses can operate without interruption. After cleaning, sugar beet is initially shredded for sugar extraction....
