PepsiCo R&D: Analysis of shear forces during mash disk formation
Allwright, David; Ballu, Marin; Correia, Joaquim M C; Chakraborty, Abishek; Cuminato, José; Ewetola, Michael; Grinfeld, Michael; Hall, CameronThis problem relates to the production of chips in a particular process. A potato composite composed of multiple mashed ingredients and small particles is fed through a spreading manifold. This forces the mash into a cylindrical mould (forming process) on a rotating drum to produce mouth sized disk pieces, which then continue to a drying process. During the forming process a scraper is used across the top of th...
Analysis of shear forces during mash disk formation
Allwright, David; Ballu, Marin; Correia, Joaquim M C; Chakraborty, Abishek; Cuminato, José; Ewetola, Michael; Grinfeld, Michael; Hall, CameronThis report concerns a forming process in which mash is forced from a spreading manifold into moulds on a rotating drum, transported in the moulds underneath a surface held flush with the drum (the shoe), and ejected from the moulds. The quality of the final product is understood to be related to the shear stresses experienced by the mash in the moulds as it is transported under the shoe. We describe and analys...
