F.B. Lehmann (www.fblehmann.de) F.B. Lehmann introduced a new generation of 5-roll-refiners which incorporate two main developments F.B. Lehmann introduced a new generation of 5-roll-refiners which incorporate two main developments. It contains five rollers, five motors, and five frequency converters. The result is a flexible, stepless adjustment of frictions between the rollers without changing gears. Different frictions are needed for different recipes. The different settings of each roller can be stored and recalled back as a recipe in the Multipanel. The speeds, and therefore the frictions, can be changed steplessly and individually. A fine selective adjustment to optimise taste, fineness and capacity is possible. Downtimes to change from one recipe to another are reduced to selecting the right recipe at the control panel. Other advantages of the five-motor concept include a reduced height machine, as no central drive unit is necessary on top. So the machine is more compact and can be fitted also into production facilities with less ceiling height. Feeding conveyor belt can also be placed very close on top of the machine. There are no gearwheels or an oil tray inside the machine body. Very easy and proper installation of the individual drives giving good access to the hydraulic system on the drive side of the machine. After re-grinding of the rollers the re-grinding of gearwheels is no longer necessary. In combination with the forced cooling water system the five-roll-refiner is said to be ideal for flexible applications and different heat-sensible products, such as milk chocolates and for very fine chocolates. Additionally, a calcium layer build up in the inner water cooling section of the rollers is prevented, as a closed cooling water loop is forseen. F.B.Lehmann also have a large range of ball mills available, to cover the whole production need for the industry also in concern of ball mill grinding starting from 50 kg/h up to 2.500 kg/h. Further equipment such as thin film reactors or taste changers, liquefiers, scraper coolers, melters in different executions for different purposes and a good range of feeding stations for liquid and powdery products and raw material treatment are produced by F.B.Lehmann. This equipment is added into the production lines depending on the requirement of the customer. Thanks to the conical, horizontal design of the grinding chamber masses with extremely narrow corn spectrum can be produced. Therefore a good flowability of the mass and fewer cause particles in the mass result. Several options are available for further optimising the product. Customers are welcome at the well equipped test centre at F.B. Lehmann in South Germany.
