Sustainable technology is a part of broader concept of sustainable product development and
sustainable development is an integral concept for achieving quality of limits, interdependence,
fundamentals and equity. Autoclave is a strong, pressurized, steam-heated vessel, as for laboratory
experiments, sterilization, or steaming. In general, this vessel contains of a view parts, they are the
body which is the cylinder part of the tank, the heads which are used as the closure of the tank, the
nozzle which are used as the fluid inlet and outlet port, and the saddle which are use to support
body/tank of autoclave. The existing condition in this research, autoclave used to steam animal food
materials and operated at 4 Bars pressured. The locking mechanisms are using 4 bolts to lock the
door of the autoclave. The design of the autoclave can be operated up to 7 Bars. The bigger pressure
operating condition, the faster processing happened.
Based on the existing condition, the goal of this research are finding and solving leakage problem in
the area between door (head) and cylindrical shell when the autoclave operates at the pressure more
than 4 Bars. The leakage starts when this autoclave operated at 4 Bars pressured. The bigger leakage
happened when the autoclave operates at the bigger pressure (7 Bars).
ANSYS software based on the finite element method is used in this research. Based on the
simulation result after re-design obtained, this autoclave can operates safely without leakage up to 7
Bars. Designing the mechanical product using ANSYS software can reduce materials, cost and time
of the product development. ANSYS software based on finite element method is a sustainable
technology for sustainable product development because simulation technology using ANSYS
software can perform the performance of the machine during the design phase and reduce materials,
cost and time of the product development.
