RESULTS OF MODELLING THE TREATMENT OF GRANULAR AGRICULTURAL PRODUCE

An important stage in agricultural production is its primary processing. This process includes a complex of technological operations. The most important of them is drying and cooling. In order to investigate conditions for rational use of energy, it is necessary to simulate the process of ventilated drying.

Another important problem is cooling of hot dried agricultural produce. An important problem is to clarify the influence of air filtration time and speed on the temperature of produce and quantity of moisture conveyance as well as pace of production cooling by ventilation during day time and at night.

In the Republic of Latvia approximately 25% of yield is dried by ventilation [1]. This type of drying becomes particularly important when prices of energy are high.

The similar problem is to describe cooling of hot dried small granular agriculture produce (grain, peas, beans, rice) by atmospheric air (cool air) ventilation. The problem's essence is to clarify the influence of air filtration time and speed up moisture transfer and the rate of heat transfer of cooling by ventilating the granular produce during day-time and at night.
