Drying leaves and shredded celery by infrared radiation

Demidov S.F., Voronenko B.A., Pelenko V.V., Demidov A.S., Dergunov M.V.

Medicinal raw materials is the whole plant. Celery leaves are used as a medicinal food plant tonic, as an anti-inflammatory diseases of the prostate gland, a diuretic in kidney disease and a tendency to be overweight. The leaves are 0.1% essential oil, vitamin "C", carotene, minerals: potassium, calcium, sodium, magnesium and phosphorus. In the roots of celery contains salts, fats, carbohydrates, fiber, vitamins B1, B2, B3, B6, essential oil, which is composed of aldehydes, ketones, acids, esters. For the drying of vegetable raw materials in our country most widely dryer steam SPK-90, CSA-80. Inside dryers located mesh belt feed is moved from one belt to another. The disadvantage of the conveyor belt dryers include uneven heating of the material due to the difficulty in applying heat to the inner parts of the layer due to lack of mixing of the material. An experimental study of the process of drying leaves and shredded celery isolated infrared wavelengths, depending on the height of the layer of leaves and shredded celery stalks, drying temperature, the heat flux density on the mesh tray made of stainless steel with a mesh size of 2 mm.
