The use of pulsed infrared drying in the processing of leafy plant raw materials

Abstract

Abstract The paper presents the results of research of leafy plant raw materials drying with pulsed infrared (IR) radiation by the example of spinach (Spinacia oleracea L.). The efficiency of the selected method for weight and humidity changes in the processed material has been analyzed. The specific energy consumption for removal of 1 g of moisture as well as ascorbic acid concentration in dried product have been calculated. The results of the analysis show that IR-drying of leafy plant raw materials is efficient and can be carried out in production environment.
