Method for producing and using kiln-dried malt

摘要

- The method comprises treating germinated malt with a water content of 10-50 wt.% in a process by planet roller reactor to kiln-dried malt. The planet roller reactor has eight planet modules that have a length of 0.4-1.2 m, where a module consists of rotating central spindle and a planet spindle rotating to the central spindle, where the planet spindle combines with an interiorly interlocked reactor wall. The planet roller module consists of central spindle and twenty four planet spindles, which run against a thrust ring arranged in flow direction at the end of the planet spindle. The method comprises treating germinated malt with a water content of 10-50 wt.% in a process by planet roller reactor to kiln-dried malt. The planet roller reactor has eight planet modules that have a length of 0.4-1.2 m, where a module consists of rotating central spindle and a planet spindle rotating to the central spindle, where the planet spindle combines with an interiorly interlocked reactor wall. The planet roller module consists of central spindle and twenty four planet spindles, which run against a thrust ring arranged in flow direction at the end of the planet spindle and are inserted in dispersing rings of different size. The central spindle, the planet spindle and/or interior reactor wall comprise a nap tooth system, where a left-hand zigzagging groove is incorporated similarly to a thread gear in a right-hand toothing. The pressure in the planet roller reactor is 500 N/cm 2>. The transmission of the reaction energy is carried out through heat conduction by tempering modules. The heat conduction is carried out over an internal and external temperature zone through the central spindle and the reactor wall. The temperature is adjusted in a value of 100-250[deg] C and the energy transmission in the reactor is controlled in order to vary and determine the color and aroma and also the digestion degree of the malt content. The time duration of the malt in the reactor is 1-5 minutes. The malt is malt unfragmentised as starch-rich raw material or green malt with a water content of 40-47 wt.%, where the 20 wt.% of green malt is used.
