เครื่องอัดแผ่นกระดานอัดจากเปลือกสับปะรดและเปลือกมะพร้าว
Abstract
The aims to study the possibility of compressing machine for producing board from pineapple and coconut peels are to help reduce agricultural refuse to produce heat-resistant board which could be used in construction industry and to decrease the quantity of imported machines which this study could produce cheaper machine to use in small domestic industry.
The machine could produce 120 x 240 x 1 cm. board from fraction of pineapple and coconut peels. In the process of production, the hydraulic pressing system is used to heat hot-oil which is inside the tube under flat iron plate. Electrical power is mainly used to supply the system.
The outcome of the study is a compressing machine which costs 550,000 baht and has a capacity of producing 48 board per 0.813 year from the current IRR of 26.17% and MARR of 5.75 %
