This paper aim on design and Development of pedal operated Seed oil extraction machine. The machine is portable which makes it light in weight and can be used for small scale industries and for Household and Pure oil extraction. Since this machine requires less space to move, it can be used in a more versatile manner as compared to heavy powered machines that are mounted on heavy and large industries. This machine can be efficient and easy to operate and maintain. The oil extracted has various applications in food, medicine, and industry (1). This paper is also aim on Literature Sur-vey on var-ious mechanism used by top Universities professors According to the Need.
Expeller presses (also called oil extractors) are a mechanical method for extracting oil from raw ma-terials. The raw materials are squeezed under high during asingle step. When used for the extraction of food oils, typical seeds such as flex, mustard, and peanut which are supplied to the press in a continuous feed. As the seeds is pressed, friction causes it to heat up; in the case of harder nuts (which require higher pressures) the material can exceed temperatures of 140 °F (60 °C). Oil expeller may be adevice which mayproduce pressure by rotating feed to expeller screw manually or automatically. Screw press method for oil extraction may be amechanical method for extracting oil from raw materials. Oil extracted by screw pressing is employedeither as a foodstuffor as an indus-trial product. Food products include raw oil in dressings and made up to vegetable oil, groundnut oil, rice bran oil etc. For this heat generation it faces some common problem including overheating, excessive thermal stress, dimensional stability and other thermal related factors. By analysing through simulating software design verification of parts used in screw presser can be modified and increase performance efficiency (2). Locally available material low-carbon steel was utilized inconstruction of the oil expeller. In the construction of oil expeller firstly it had beendesigned and validity of stress checked in Ansys. After constructing the oil extraction barrel rectangular bars were placed surrounding it as it permits the passage of oil only and helps to create pressure inside the barrel. The choke mechanism was set in the screw at the outlet of extraction barrel. It was adjusted accordingly to regulatethe output of wastage and to extend and reducepressure accordingly. A reducing gear was used to reduce the rpm of the motor and to increase the energy in the screw shaft (3). Power is transmitted by using pedal which is maintained at gear ratio 18:44 which is for smaller and larger sprocket respectively. The gearbox is connected at output of smaller sprocket shaft. The gearbox used is worm and pinion gearbox which rotates the lead screw at 140 rpm.
II. DESIGN CALCULATION
The gear ratio of the chain drive will be 2.44, the velocity of chain drive will be 0.9309 as we taken the speed of the revolu-tion of larger sprocket N1 = 100 rpm. It can be increased by increasing the power output of the chain drive. Therefore we use worm and pinion gearbox which is connected directly to the main shaft of the lead screw, the gear ratio of the gearbox will be 0.6 which gives the output of 146.4 rpm. The length of the chain will be 2.1 m which will be open and connected to the input shaft of the gearbox in the end.
