Modeling of drying process of wood raw material for its subsequent use at fish smoking

Abstract

Models of many technological processes (drying, Smoking and drying fish) are described by equations. Such models and applies the model of drying process of raw materials for example wood drying. The article considered a model of drying of raw materials based on the heat equation with variable coefficients. Physical properties of wood during the drying process change, and therefore the equation coefficients are changed according to some given law. The model becomes essentially nonlinear. As a rule, to obtain the solution for such models explicitly impossible. In this case, it becomes the actual task of developing numerical methods for solving model equations and writing of appropriate programs for computer simulation of technological processes. The existence of such programs allows researchers to solve the problem of selecting the optimal parameters and the optimum conditions of the studied technological processes to determine the time required to achieve the desired values of the objective functions. Based on the calculation formulas developed simulation program of the thermal field in MatLab that can be used to simulate the drying process under different conditions. The article provides examples of model calculations for different values of parameters of raw materials. Processes associated with heating or drying of the feedstock, are observed when Smoking or drying fish. The suggested algorithm can be, after some modifications, used for their modeling.
