Department of Engineering, ICT and Technologies for Energy and Transport Patent Title Machine able to separate the ĮďĞƌ and the shives from hemp for industrial use. Ref. CNR 10318 Assignee(s): CNR, Assocanapa CNR InƐƟƚute: IMAMOTER Main Inventor: Renato Delmastro Countries: IT Priority date: 28/06/2010 Abstract Machine capable of receiving and working long-Įber hemp harvested in round bales. It can to separate and collect the ĮďƌŽƵƐ part and the shives ensuring a degree of cleanliness conform to the values required by the market. Background Hemp ĐƵůƟvĂƟŽn has experienced a sharp decline in produĐƟon due to the excessive cost of labor needed for its ƉƌŽĚƵĐƟŽŶ and preparĂƟŽn. The object of the present inveŶƟŽn allows to drĂŵĂƟĐĂůly reduce the Ɵme and hence the cost of prepĂƌĂƟon, making possible a high-quality product with compeƟƟve prices. Technology The machine is composed of three main parts: the feeder/power pack, the separator that separates Įbers from shives using three co-roƚĂƟŶg rotors and the cleaner of the Įďer. Two prototypes are available: the Įrst one is powered by a farm tractor drive shĂŌ PTO, while the second is powered by an electric motor. Advantages and ApplicaƟons The machine allows to work the bales of hemp by means of a single ŽƉĞƌĂƟŽn; it is able to directly receive the bale of hemp, to separate the Įbrous part from shives and to collect the two components for subsequent processing steps. The hemp ĮďĞƌ is required by the texƟůĞ and construĐƟŽn industries; the shives have interesƟŶŐ characterisƟĐƐ in the ĮĞůĚ of auƚŽŵŽƟǀĞ products and buildings insuůĂƟŽn. Development stage The Įrst prototype made it possible to assess the beneĮts and the changes necessary to improve the working eĸĐŝency. The second prototype, ĂŌer the engineering phase, will increase the hourly prodƵĐƟŽŶ and the quality of the product, in order to ŽƉƟmize costs and match market requests. 21
