Abstract

Spray drying is widely used for dehydration of dairy products and among, the most energy-intensive unit operation in this field. An optimization problem for a production scale milk drying system was implemented and solved, considering plant capacity (maximization) and energy consumption (minimization) as the objective. Decision variables were inputs to the spray unit namely the inlet dry bulb air temperature, concentrate moisture, and dry solids flow rate. Product stickiness conditions and moisture content were the main constraints, which were modeled using mass and energy balances. A non-deterministic derivative free based optimization technique, namely Markov Chain Monte Carlo (MCMC) algorithm was chosen to solve the problem. The results showed that throughput maximization is achieved at the expense of a relative energy consumption penalization in the spray and revealed that the structure of the problem seems to be convex. This study shows a promising non-conventional use of MCMC algorithms in optimization studies.
