Utilisation of malt sprouts in the malting plant
The companies Weyermann® Malz and Tietjen have been business partners since the 1980s. Weyermann® Malz produces barley, spelt and wheat malts for breweries and the food industry in its malthouses. Tietjen mills have been in use at Weyermann® Malz for many years. Both the high-speed mill VL and the self-feeding mill HM grind the malt sprouts. The high-quality, protein-rich end product is used as a feed additive.
Replacement of the old hammer mill and investment in occupational safety and explosion protection
The sprouts are extremely abrasive and the antiquated, heavily worn mill at the Haßfurt plant had to be replaced. At the same time, Weyermann® Malz wanted to invest in reliability, work-place safety and explosion protection.
Mr Buhrmann, General Operations Manager at Weyermann® Malz, is very satisfied after 3 months of using the new self-feeding hammer mill type HM2 in operation:
“The mill grinds the sprouts very finely while increasing throughput at the same time. In addition, the silo capacity has been increased by 25% due to the fineness of the ground material.”
Mr. Buhrmann and the team leader for machine maintenance, Mr. Precht, are also very satisfied with the significantly lower noise emissions compared to the old machine.
Tietjen supplied the explosion-decoupled HM2 mill, which is self-conveying over 25 meters, a feed pipe chain conveyor, a conveying pipe system with explosion decoupling, two cyclone separators for the two silos and the control cabinet with control system. A particular challenge was the limited space available and the building conversion during ongoing operation. In addition, the installation of the cyclones above the external silo at a height of approx. 25 meters with corresponding height safety devices is quite complex.
