Abstract: The application of vacuum impregnation technique for soaking of Gulabjamoon in sugar solution was conceptualized and the equipment was designed and developed. Vacuum impregnation unit (VIU) was operated under vacuum and hence the design of its wall thickness was of critical consideration. VIU facilitated rapid soaking of Gulabjamun in sugar syrup under full vacuum in cyclic process. VIU is cylindrical in geometry, designed to work at 65-80 ºC at 5 kPa pressure (vacuum) on the inside and was exposed to atmospheric pressure on the outside. This leads to compressive forces acting on inside of the cylinder wall. The shell thickness will have direct bearing on stresses developed. There will be implosion (due to compressive forces) of VIU when Von Mises stress generated is more than yield stress of stainless steel (205 MPa). Wall thickness of cylinder of VIU was optimized by Finite Element Analysis (FEA) by modeling and simulation using Pro/ENGINNER. ANSYS-14 was used for analysis of Von Mises stress, deformation and factor of safety. The wall thickness of shell was analyzed by hyper tetrahedron meshing. To validate, design software developed by ASME was used for shell thickness determination. The model prediction was shown to be in good agreement with the analytical calculation. The FEA resulted in Von Mises Stress of 135.79 Mpa, deformation of 1.55 mm and factor of safety of 1.5. VIU was fabricated as per FDA C-GMP standards from 4.00 mm thick AISI-316 SS material. The working drawings were developed and actual fabrication was carried out adopting the prescribed sanitary standards. The unit was subjected to various safety tests and it successfully passed out all of them. Satisfactory production of Gulabjamoon was carried out in the newly designed and developed equipment resulting in a product of excellent quality confirming validity of the design.
