Malt, Barley, Steeping, Step, Transformation. Equipment
Traditional malting is a batch process that takes place in three discreet process vessels, with grain transfers between the vessels for each process step. There are no continuous processes in traditional malting. The three malting process steps are steeping, germination, and kilning.
This lecture will first cover the purpose of steeping and its role in the malting process, the equipment requirements for steeping, and examples of the two major steeping equipment configurations, with the pros and cons of each configuration. With an understanding of steeping equipment and utility requirements, the steeping process sequence, and the tools that the maltster uses to manage the steeping process are discussed.
