Rapid ribbon mixing in Helical Blade plant at their Congleton factory. As Brian Jones, Tate & Lyle’s Engineering Manager, put it; “I have known JR Boone for many years, and they have proved their ability to support us technically, both here and in our factories overseas. We ran supervised trials, with the mixed products then going through our full QC test procedure, which they passed successfully”. As mentioned above, the factory has very strict requirements for clean- down between mixes. The JR Boone mixer was fitted with two full-width doors to make it easy to clean every inch of the mixer interior, so much so John R Boone have supplied a new, Brisbane Australia. that cleaning only requires around ten high-specification, easy-clean Helical Along with other manufacturers, JR minutes.
