There are several types of corn threshers, each with distinctive features and capabilities. Some of the most widely used types are discussed below:
Traditional Manual Corn Threshers
Traditionally, corn threshers were all done manually. Before the invention of machines, threshing was done by trampling the cobs with the help of livestock. This was a rural practice that required a lot of time and physical exertion. Modern manual threshers are simple and come with a hand crank. Although it is difficult, affordable corn threshers offer an eco-friendly way of processing corn. Some models come with a pellet bag for further use.
Mechanical Corn Threshers
Mechanical corn threshers are operated through different kinds of small engines. Some have car-like tires and are pulled by vehicles on farms, while others are mounted on tractors or towed behind. A lot of them use roller systems to remove kernels. The rollers mash the cob lightly so the kernels can be released without damaging them. Once the kernels are out, the rollers release the residuals which can be used to make biofuels and farmyard manures.
Motorized Corn Threshers
Motorized corn threshers are specialized machines that extract corn kernels efficiently. Most of them work with two rollers. Corn is fed in between the rollers where the kernels are scraped off. This method prevents damage to the kernels and is used widely in commercial settings. After processing the cob, the residuals are collected and can be further processed into biogas or manure.
Power-Driven Corn Threshers
Post-harvest corn production often involves using a power-driven corn thresher. It is independent of manual operation and is an efficient way to handle a lot of corn. These machines are usually pulled behind a tractor and are attached via a three-point linkage system. It has a power take-off shaft that connects the engine's output to the eating mechanism of the corn. Power-driven corn threshers work excellently and are cost-effective in processing large volumes of corn.
Rotary Corn Threshers
The rotary corn thresher has a threshing drum and feeding mechanism to push corn into the drum. The drum turns at a high speed and removes the kernels through centrifugal movement. Rotary corn threshers are mostly used in big farms because of their efficiency and high production rate.
Purchasers of corn threshing machines typically look at a few key specifications.
Capacity
The capacity is usually represented using tons per hour. It indicates the amount of maize that the machine can process in one hour. Businesses typically choose machines with high capacity. A machine with a high capacity will increase productivity and save time.
Power source
Threshing machines have different power sources. Some use electricity, while others use diesel engines or hand cranking. An electric corn thresher machine will require a stable electricity supply to function. On the other hand, a diesel corn thresher will need a constant source of fuel. Businesses will choose a power source that matches their needs.
Durability
The materials used to build the machine affects its durability. Machines built with metal are more durable than those built with plastic. More durable machines will cost more, but businesses will have to incur fewer replacement costs.
Dimensions
The dimensions of the machine also affect its processing capacity. Some machines are very compact, while others are large. Larger machines tend to process more grain than smaller ones.
Efficiency
Some machines separate the grains and cobs more efficiently than others. A well-efficient machine will reduce wastage and yield more grains.
The function, efficiency, and lifespan of a corn thresher will depend on regular maintenance. Let’s look at some recommended maintenance tips for a corn grain thresher.
Daily inspection
The user manual will outline all the daily maintenance tasks that must be performed before and after using the machine. All corn threshers require a daily inspection. The grounds and fasteners will be checked for blockages. The electrical wiring and belts will be checked for damages and adjusted as needed.
Periodic oil changes
Once every three months, the machine's oil will need to be changed. During the oil change, the machine will be lubricated. This will include all moving parts such as chains, bearings, and shafts. The grease fittings will be lubricated as well.
Deep cleaning
Every three months or so, a thorough deep cleaning of the machine will be required. This may be done after the threshing season as well. All cob and kernel residues will be removed from the machine. A blower or air compressor may be used to flush out debris from hidden parts.
Electrical maintenance
Every six months, the electrical system of the machine will have to be inspected. All wiring connections will be checked. The wiring will be inspected for rat bites and breaks. Damaged or worn-out parts will be replaced as needed.
Often found in large-scale farming and commercial corn production, an electric corn thresher machine offers a labor-saving method to extract corn from cobs rapidly and efficiently. Because of this, it has become a very important tool in the corn-processing industry.
Apart from increasing productivity in harvesting corn, threshers also accelerate production processes in various corn-based industries. Many tons of corn can be shelled in a single hour. This high efficiency transforms the otherwise lengthy threshing process into an easy and fast task.
Corn kernels separated by a thresher are directly processed into products such as tortillas, chips, taco shells, and corn syrup. Industries that manufacture these products often use threshers to increase their production rate and improve inventory to meet the demands of customers.
Besides food production, corn kernels are ground into corn starch and syrup to manufacture biofuels. Some are also used in animal feed. Corn thresher machines help extract corn efficiently for these industries to produce energy and animal feed. Thus, they can also reduce the carbon footprint by expediting the creation of biofuels and thrice separating corn that would have released energy on combustion.
In addition to agricultural, food, and energy industries, corn-threshing machines are invaluable in research and seed-breeding sectors. Corn-thresher machines provide a precise and systematic method for extracting kernels from specific corn varieties. They allow scientists and breeders to evaluate genetic traits, analyze yield potential, and assess quality characteristics closely. By efficiently separating the kernels, corn threshers facilitate the examination of seed composition, enabling researchers to identify and select superior varieties for further development and testing.
Even small-scale organic farms benefit from corn shelling machines, as many models are available that can also be powered with minimal electricity or even by hand. Because of this, organic farmers can harvest their own organic corn and save energy and resources as they prepare their produce for sale.
Given the diverse applications of corn cob threshers across agricultural, industrial, energy, research, and small-scale farming sectors, their significance in optimizing corn utilization and improving efficiency cannot be overstated.
