A multi grain seed sheller is a kind of threshing machine specially designed to separate the outer husk or shell of various types of grains from the edible grain. It performs the process of shelling without damaging the seeds or grains. Multi grain shellers provide an efficient solution for farmers and agricultural industries to prepare grains for consumption, planting, or further processing. Different types of multi grain shellers are described below:
Mechanical shellers
Mechanical shellers are designed to be operated either by hand or foot. They use a crank, lever, or pedal system to thresh grains. Mechanical shellers are made from cast iron for long-lasting use. They are compatible with various grains, such as maize, wheat, barley, millet, chickpeas, peas, rice, and beans. The shellers usually have a feed hopper, where un-husked grains are supplied for processing. It also has a rotating drum with a textured cylinder that separates the husk from the grains through friction and abrasion. After processing, the sheller provides separate outlets for the husked grains and the husk. The outlet provides easy access to the processed grains for further use or storage.
Mechanical shellers help users to separate grains efficiently. They are not dependent on power sources and are mostly used in areas without electricity. However, the shellers require physical effort to operate, and the capacity of the shellers may be low compared to electrical or automated options.
Electrical shellers
Electrical or electric grain shellers work the same way as mechanical shellers but have a motor-driven mechanism for grain separation. Electric shellers are compact machines. They have a feed tray for unprocessed grains. The sheller also has a motorized rotating drum that separates the grain from its shell by friction. The processed grains go through a separate outlet. The processed grains can amount to a few hundred kilograms to several tonnes, depending on the size of the sheller and the power of the motor. An electric sheller is easy to operate and provides a better output than a manual sheller.
Electrical shellers have the advantage of higher productivity in seed shelling. They are, however, dependent on electricity for operation. In case of power outages or electricity unavailability, electrical shellers cannot function. The power consumption of electrical shellers may be high in some instances, which can be costly.
Pneumatic shellers
Pneumatic shellers use air pressure to separate grains from their shells. They have a fan or blower that blows air to create the pressure necessary for separating the two components. Pneumatic shellers are used widely in rice mills. They separate the rice grains from the paddy by applying air pressure while the paddy is moving over a screen. The rice grains fall into the designated container, and the husk is carried away through the air stream in a different direction.
Pneumatic shellers are more efficient than mechanical and electrical shellers in separating grains. They are extremely useful in large-scale rice production facilities. However, like electrical shellers, they require a constant power supply to operate. The complex operation makes maintenance necessary at regular intervals.
Universal threshers
Universal threshers are large machines designed to process multiple crops without changing the main components. They are used widely in commercial farms for large-scale production. While universal threshers process grains efficiently, they are very expensive and may not be cost-effective for smaller farms that do not produce large quantities of crops.
Some shellers might have different specifications based on their design and capacity. Some key specifications to consider include the shelling capacity, shelling efficiency, grains compatibility, noise level, energy consumption, and the structure and material.
To get the best out of any shelling machine, it is important to schedule maintenance. This will help reduce the risk of breakdowns and prolong the life of the machine. It also minimizes grain loss and improves shelling efficiency. The first maintenance tip is to inspect the sheller parts regularly. This includes identifying any damages or wear and tear that might need immediate repair. Be on the lookout for loose bolts and nuts and any unusual noise that could signal a problem.
Secondly, clean the machine thoroughly after use to prevent build-up of any debris or seed residue that could affect its performance. It is also important to lubricate the moving parts of the grain sheller to ensure smooth operation. This also minimizes chances of wear and tear. Follow the manufacturer’s guidelines when it comes to maintenance practices and avoid using unauthorized spare parts.
The multi-grain seed sheller illustrates its versatility across industries and sectors. In some rural settings, it can still be used to provide power through a pedal to serve as an alternative to electricity in shelling grains. It can also be used, as mentioned earlier, together with a seed cleaner, which also has different types of motors for cleaning seeds and may be used in conjunction with a seed sheller for further processing of seed grain. These machines are sometimes blent in disassembly lines in food industries where maize, rice, and other grains are prepared for consumption; grain includes a part of the ingredients that must be removed before usage.; thus, shelling is an essential part of the process.
Grain shellers may also be used in animal feed production to assist farmers in preparing feed for cattle, poultry, and other livestock, constituting part of the animal's feed, especially when it concerns corn, which must be shell before it can be ingested or used in its entirety. Grain shellers are also used in trial fields to verify and evaluate the performance of various agricultural machinery, including their efficiency, capacity, and the quality of the grain remaining after shelling, to set standards – not to mention the farm management practices that must be adhered to when conducting these trials on farms or research facilities.
A grain sheller may be necessary in certain labor-intensive industries or small-scale production processes to increase the productivity and efficiency of grain processing. In large commercial farms, grain shellers are vital to quickly process a large volume of grain, contributing significantly to the food chain and economy.
In developing countries, grain shellers may have a socio-economic impact by facilitating grain processing for local consumption or sale. This process increases the value of grain products and generates opportunities for employment and economic growth. Where the grain sheller is not available through technology, manual knowledge of the traditional way in which this was done must be taught and used to educate the next generation of farmers.
It is essential to have case studies that illustrate the grain sheller's impact, efficiency, technical implementation, and contribution to sustainable agriculture and economic development. By sharing best practices and success stories, rural farming communities can benefit from adopting grain shellers, leading to increased productivity, improved food security, and enhanced livelihoods.
