Abstract

Tehnologija sušenja duhanskog komposta uključuje proces pripreme duhana, izrade cigareta, sakupljanja sirovina (otpada) za duhanski kompost, kompostiranje te sušenje komposta. Kao materijali u ovom radu su korišteni uzorci duhanskih sirovina Svijetle Virdžinije i Burleya. U radu je praćeno sušenje slojeva duhanskog komposta različite debljine, na zraku, pri temperaturi od 20˚ C, u periodu od 40 dana. Na osnovi dobivenih podataka određena je brzina sušenja za svaki sloj. Udio vlage u uzorcima je određivan klasičnom metodom sušenja do konstantne mase te metodom infracrvenog sušenja. Mjerenja su pokazala da najveću brzinu sušenja ima najtanji sloj, no s obzirom na količinu osušenog komposta ovaj sloj nije i najidealniji za sušenje. S obzirom na konačnu vlažnost i količinu osušenog komposta, sloj debljine 5 cm (u odnosu na maksimalnu moguću debljinu od 30 cm - sloj 1:6) se pokazao kao najidealniji među šest slojeva koji su sušeni.

Abstract (english)

Technology of tobacco compost drying includes processes of tobacco preparation, cigarette production, collection of raw tobacco left-overs for tobacco compost, compost production and compost drying. As materials in this work have been used Light Virginia and Burley tobacco. Tobacco compost layers of various thickness have been dried on air, on temperature of 20˚C, in period of 40 days. Speed of drying process for each layer has been shown, based on research results. Moisture portion in speciments has been measured by classic method of drying and by method of infrared drying. Results showed that the thinnest layer has the highest speed of drying, but considering the quantity of dried compost this layer is not optimal for drying. Regarding the final moisture and quantity of dried compost, 5 cm thick layer ( compared to maximal possible thickness of 30 cm – 1:6 layer ) has proved to be optimal between six layers which have been dried.
