Food-grade stainless steel tank, 1000 L on skid

Concept design of a 1,000 L atmospheric tank in AISI 304 for food and beverage plants, on a transport skid. Portfolio concept project, not a manufactured product. Scope: 3D CAD in SolidWorks (22 parts, 4 sub-assemblies), structural verification in ANSYS, hand checks in MATLAB and KeyShot renders. Design: vessel ID 1000 x 1250 mm in 3 mm sheet, 15 degree conical bottom for full drain, DN400 manway, clamp-ferrule nozzles, DN50 outlet line with butterfly valve, four tubular legs on a 1300 x 1300 skid. Empty mass 258 kg. FEA: shell-and-beam model with 93,000 elements. Full of liquid at 1,200 kg/m3 the peak von Mises stress is 52 MPa at the cone-to-shell junction against a 140 MPa allowable. Mesh convergence and equilibrium were checked, and hand calculations agree with the FEA.
