End-over-end (EoE) rotation of toroidal cans: An experimentally validated mathematical modelling study

Toroidal cans have been presented recently to improve the canning process efficiency, and previous studies focused on static and axial rotational processes. End-over-End (EoE) rotation is a significant agitation approach to increase the temperature uniformity of liquid canned products, and it would be important to observe the effect of this process combined with the toroidal cans. Therefore, in this study, this combined effect was considered to improve the process in the view of temperature uniformity. For this purpose, a computational numerical model was developed using - Star CCM+, and this model was validated with experimental data. Then, the rotational rate and headspace amount effects in a toroidal can geometry, including a liquid, were determined using this validated model. The numerical results indicated that these parameters influenced the heat transfer process with a resulting uniform temperature distribution through the EoE processing. •A computational model was developed to determine the EoE agitation on toroidal cans.•Mathematical model validation was carried out with experimentally obtained temperature data.•Effects of headspace amount and EoE rotation rates were evaluated.•A significant temperature uniformity obtained with the EoE rotation effects was demonstrated.
