PROJECT- PEANUT PEELER

NEED STATEMENT-PROCESSING MACHINE

GUIDE-NANDISH HUMBI

Peanut peeling machine is one of the most important tools for agricultural development. It is mainly used to roll rubbing peeling method, it has stable and reliable performance, long service life, its half grain rate is low, good quality and so on, suitable for processing all kinds of peanut.

INDUSTRIAL USED MACHINE

!The peel structure of peanut peeling machine Mainly have steel bar or steel grid concave plate structure, rubber roller or rubber floating concave plate structure. Peeling machine made from the rack, a fan, a rotor, a single-phase motor, the screen (size two), into the hopper, vibration screen, belt pulley and the transmission belt. After the normal operation of the machine, the peanut is fed into the hopper in a quantitative, uniform and continuous manner, and the peanut shell is broken under repeated attack, friction and collision of the rotor.

Under the rotating wind pressure and blow, peanut kernels and broken peanut shells through the aperture of the screen (peanut first shelling with a large hole sieve threshing, after cleaning, replaced small hole screen mesh to conduct the second shelling). At this time, peanut shell and kernel suffer the blowing effect of rotating fan. The peanut shell with light weight is blown out of the machine, the peanut particles are screened by vibrating screen to achieve the purpose of cleaning. The working steps of soaked peanut peeler machine

• Soak the peanuts in hot water at 90 degrees centigrade, and take them out when the red skin can be rubbed off by hand.
• Place the peanut into the peanut peeling machine.
• Under the force of the peeling roller, the red skin and inner peanut are fully separated. During the process, you should spray the water onto the peanut, which is good for the peeling.
• The peeled peanuts finally come out from the outlet and the red skins are discharged from the back of the peanut peeler machine.

PROTOTYPE PROJECT

This work is related to design and development of electrically operated roasted peanut peeling machine and testing and analysis of peanut which includes size variation, compressive strength, roasting temperature and time of roasted peanuts. There are basically two types of peanuts which are widely used for domestic and industrial applications of food products they are Java type and bold type. Bold types of peanuts are used in our work as they are mostly used in confectionary and food industries also out of total peanut consumption 60% to 70% are of bold type as well as its compression strength is greater than other peanuts, reason for this is, it is long in length and sweet in test than other. From our observations it is found that the length of peanuts varies in the range of 14mm to 18.4mm and diameter of peanuts varies in the range of 9mm to 10.6mm. The average compression strength of bold type peanuts with roasting is 308 gram/cm2. For effective peeling, peanut should be sand roasted and sand temperature is kept in the range of 150°C to 160°C for 45 seconds to 60 seconds. In testing an average of 5.042 kg of roasted peanuts was fed into the machine; this produces an average mass of 3.989 kg of peeled roasted peanuts, 0.605 kg of unpeeled peanuts and 0.448 kg of broken peanuts. An average time of 248 seconds and efficiency of 79.129% was recorded. The machine is easy to operate and has a peeling capacity of 75kg/hrs. With this capacity this machine can be useful in confectionary and food industries for need of peeled roasted peanuts.
