This machine is designed in such a way that all the three processes:
Roasting of groundnut, Separation of groundnut shells from the groundnut seed, and the oil extraction is done in a single unit without any human interference.
The machine components are:
bowl feeder, crushing rollers, conveyor tray, vibrating tray, hopper and extracting chamber.
The fabricated machine is then tested to establish the influence of moisture content, heating time and temperature on percentage oil yield. The machine has an extraction capacity of 85 kg/hr with the screw shaft rotating at 53 revolutions per minute and a reduction gear to step down the speed of rotation to ratio of 27:1. The roaster was equipped with; a barrel heater. The machine gave the highest oil yield of 28 %, an equivalent of 64% when compared to 45% oil content of groundnut, at 100oC, heating time of 15minutes. The overall cost of the machine was Rs. 45,000.
ABOUT THE ENTRANT
Type of entry:individual
Rishabh is inspired by:Traditionally, groundnut oil extraction involves shelling the groundnut pods, roasting the shelled groundnut seeds, de-skinning/winnowing the roasted groundnut seeds, milling the cleaned groundnut seeds and kneading the paste produced. Hydraulic press and screw expelling machines were also developed to avert the drudgery and inefficiency involved with the traditional method. Several groundnuts shelling machines and oil extractors has also been fabricated. The problem with these designs is that it is a single unit of oil expelling machine. Machines which could combine roasting of the nut and expelling of the oil from the nut are not commonly available. However, if some of these units can be integrated it can generally enhance the efficiency of the entire process. An expelling machine for extracting oil from groundnut was thus designed and fabricated. This machine is designed in such a way that all the three processes: Roasting of groundnut , Separation of groundnut shells from the groundnut seed , and the oil extraction is done in a single unit without any human interference.
