Hi there, We are making whisky with a grain-in process. The mash is pumped from the mash tun to the fermenter with a centrifugal pump and stays there without agitation. After a week the grain is settled at the bottom and the husk is floating dry at the top. It is a hell of a job to pump this to the still after it is settled. I am thinking about using a lobe pump but I am not sure this will work with the solid at the bottom. The other solution would be to add an agitator to keep the mash homogeneity. Does anyone ever had this problem with a grain-in process? Did you try a lobe pump or other solution? Thanks!
