Abstract

The paper presents an automated system for processing fruit and vegetable products, which includes such technological operations as steam peeling (thermovacuum method), cutting, convective and vacuum drying of fruit and vegetable products. For efficient operation of the plant a control system is used, which provides full automation of the whole complex of technological elements. The plant has a high level of energy efficiency, as it uses thermal accumulators (with the effect of thermomagnetic convection) and heaters with temperature self-regulation. The parameters of the operation modes of thermal accumulators agree with the operation of the heater with adaptive energy consumption (with variable power and constant temperature) depending on the temperature of heating of plant raw materials. At the first stage, when intensive heat flow is required for drying - thermal accumulators provide inertia-free heating of horticultural products. The function of the heater is connected with controlled heating depending on the temperature of plant raw material, providing heat flow correlated with the operation of thermal accumulators. The use of combined and adaptive heating from thermal accumulators and electric heaters allows for uniform temperature distribution (temperature field), which ensures efficient processing of vegetable raw materials. Automated change of heating power from electric heaters and thermal accumulators provides the possibility of adaptation to any power electric network based on the need for the level of processed horticultural products, and the use of thermal accumulators allows to accumulate thermal energy from solar collectors.
