Abstract
It is known that the cooling of food prevents the reproduction of microflora, thus contributing to the preservation of the beneficial properties of products. Despite this, the cooling process is still the least studied stage of cold processing, which necessitates further in-depth study of the problem discussed in the article. Given the diversity and volume of processing facilities and the energy resources they consume, it is important to justify the analytical and numerical apparatus to address many engineering and plant-based cooling products of technological challenges. Below, in the article, computer-based tools are used to be different from the method used conveniently enough for practical purposes to quantify and calculate the common in production process of food freezing.
Highlights
It is known that, along with the problem of cooling plant-based substances, while achieving a reduction in energy costs, a similar problem is forced to solve, in general, and the entire human community in a wide variety of tasks to justify the most rational technologies in the field of organic and inorganic systems
The problem is solving on the basis of the model of the paired task of the cooling of the heat transfer task of Stefan for two zones of product I and II in two different aggregate states
Inside each of the frozen and cooled zones I and II, the temperature of the environment in spherical coordinates satisfies the differential equations of thermal conductivity and the boundary conditions of the first kind (Fig. 1)
Summary
Along with the problem of cooling plant-based substances, while achieving a reduction in energy costs, a similar problem is forced to solve, in general, and the entire human community in a wide variety of tasks to justify the most rational technologies in the field of organic and inorganic systems. The task of forming frozen and cooled areas of the body in question is interpreted as a complicated (due to phase transition) change in the aggregate state of the environment, the problem of heat exchange between the cooled zone I and the frozen zone II (Fig. 1). The problem is solving on the basis of the model of the paired task of the cooling of the heat transfer task of Stefan for two zones of product I and II in two different aggregate states. On the basis of the developed algorithm, the quantitative dependence of the coordinates of the temperature front on the time of the freezing process of the preparation is justified, at different values of temperature indicators on the boundaries of zones and the content of the product
