Computational Fluid Dynamics (CFD) Simulation of Mixing Tank at Milk Powder Factory to Reduce Material Losses

Industrial milk powder production applies the principle of a spray dryer. In powdered industry using dryer, there are still some problems in actual conditions such as fouling heat exchanger and losses. Losses lost material or time so that result losses for company. The importance finding soon possible it is to make solution initially unknown wasted vain can be used finished good. Steps taken resolve problem identify data by making mapping according conditions. After that, CFD mixing tank simulation performed on Ansys with aim get contour foaming phenomenon find out height (foam) properties set up begins at beginning geometric designs size 3.5 m uses marine propeller type, then proceeds meshing geometry, here automatic method due limited analysis students. after solving stage carried inputting density, viscosity input multiphase (mixture), viscous (Large Eddy Simulation), boundary plane from results running form choose volume fraction phenomena occur conclusions solutions drawn. Based field quantity losses, wet dry have not been identified, percentage ratio 40.57% 9%. One biggest contributors tanks which simulated until known phenomenon. It interferes way works level sensor causes less maximum withdrawal liquid pump. best right reduce close valve output when showing 1.8% rounded 2% safety product 270 liters equivalent 113 kg. If calculation out, company store 8,505 kg/month powder.
