Peanut Shelling
A typical shelled peanut processing flow diagram is shown as the following. Shelling begins with separating the foreign material with a series of screens, blowers, and magnets. The cleaned peanuts are then sized with screens (size graders). Sizing is required so that peanut pods can be crushed without also crushing the peanut kernels.
Next, shells of the sized peanuts are crushed, typically by passing the peanuts between rollers that have been adjusted for peanut size. The gap between rollers must be narrow enough to crack the peanut hulls, but wide enough to prevent damage to the kernels. A horizontal drum, with a perforated and ridged bottom and a rotating beater, is also used to hull peanuts. The rotating beater crushes the peanuts against the bottom ridges, pushing both the shells and peanuts through the perforations. The beater can be adjusted for different sizes of peanuts, to avoid damaging the peanut kernels. Shells are aspirated from the peanut kernels as they fall from the drum. The crushed shells and peanut kernels are then separated with oscillating shaker screens and air separators. The separation process also removes undersized kernels and split kernels.
Following crushing and hull/kernel separation, peanut kernels are sized and graded. Sizing and grading can be done by hand, but most mills use screens to size kernels and electric eye sorters for grading. Electric eye sorters can detect discoloration and can separate peanuts by color grades. The sized and graded peanuts are bagged in 45.4-kg (100-lb) bags for shipment to end users, such as peanut butter plants and nut roasters. Some peanuts are shipped in bulk in rail hopper cars.
material and are later separated by winnowing. The device works best for jatropha curcas, shea, dried coffee, and peanuts (groundnuts).
The peanut shelling machine need feed material by labor first and automatically feed by wind fan connected to the machine. The fan automatically winnows the harvest (separates the shells from the nuts). The peanut shelling machines are capable of shelling the same variety of crops such as jatropha curcas, shea, dried coffee etc. The processor also provides access for the winnowing section to be used independently from the sheller. This allows winnowing of crops that are not shelled, such as rice, maize, sorghum etc.
The second component of our system is a device that separates the shelled kernels from the shells. Prior designs for separation equipment use forced air to carry the shells away from the kernels. Since forced air requires complex fan units and extra power, we designed a separation machine that does not depend on air currents. Our design uses the round property of the kernels to separate them from the husks. The round kernels roll in contrast to the shell fragments, which are flat and may have fibers sticking out at the broken edges. Our separator places the combined kernels and shells onto an inclined plane where the round kernels roll down the plane, and the shell fragments stick on the sloped surface.
A Low-Cost Peanut Sheller
In places like Haiti and many West African countries, peanuts are a major crop. Most peanut farmers shell their peanuts by hand, an inefficient and labor-intensive process. The peanut sheller is small and inexpensive. It fits well into the household peanut industry, which is to serve technologically where peanuts are grown, processed, and marketed. The simple, low-cost peanut sheller is economical for use by households and small workshops.
The peanut sheller, with sufficient market penetration, would offer a substantial increase in shelling efficiency. Most shelling is done by hand in peanut-producing regions of the developing world. The peanut sheller of our products feature low-cost, easy operation and high efficient. The peanut sheller could significantly reduce peanut processing time for the worker, opening up time for other tasks. The peanut sheller could be applied in peanut process workshop for industrial production. It is advanced in technological progress and agricultural innovation for many parts of developing world.
We are a professional machinery company offers nut seeds cleaning equipment, vegetable cleaning machinery, grain and seed cleaning equipment from China. Our goal is to serve advanced peanut processing technologies for customer. We are professional in the equipment for peanut shelling, oil pressing, and other general grain machinery.
