Modeling the operating costs for production of the hydrolyzate

Abstract

Nowadays, the waste management is an important issue. In this paper a mathematic modeling of the main operating costs for production of collagen hydrolyzate from leather shavings is presented. The model is based on physical and chemical ongoing processes in the reactor and other parts of the production system, such as kinetics of the hydrolysis, mass and dry matter balances and protein balance in equilibrium. The aim is to determine optimal time of hydrolysis reaction, optimal mass fraction of decomposed protein and hence the main operating costs. The modeling is performed for a batch reactor and pilot plant conditions. © Springer International Publishing AG 2018.
