Bean sheller machine

Types of bean sheller machines

The bean sheller machine serves as a crucial asset in the grain processing industry. Various models and types of this machine exist to accommodate diverse requirements.

• Mechanical contraptions

  The mechanical contraptions derive power from electric sources, enabling them to efficiently remove beans from their pods. Operating this machine is a straightforward task, as one only needs to feed in the beans, and within a short duration, they will have shelled beans.

• Manual bean sheller

  The manual bean sheller stands out for its easy portability and affordability. It provides a viable solution for individuals who lack access to electricity, enabling them to shell beans in remote areas. Though operated by hand, this machine increases bean shelling speed compared to the traditional method of using one's fingers.

• Power bean sheller machines

  Heavy-duty bean shellers are also referred to as power bean sheller machines. Such machines derive their energy from an electric motor or a gasoline-powered engine. They can operate at higher capacities and are ideal for commercial-scale bean shelling.

• Walk-behind bean sheller

  This machine calls for one to use it together with a walking tractor. It works perfectly well in countries that don't use bean pod stripping due to the unavailability of labor to harvest beans. It has been reported that such a machine increases harvesting efficiency by ten times compared to manual harvesting.

• High-efficiency bean sheller

  This bean sheller type excels in terms of efficiency. It is fast and cuts down on operational costs. Besides, it is designed to uphold the integrity of the beans, which are often expensive. In addition to this, the machine smoothens the processing line.

Specifications and maintenance of bean sheller machines

The bean shelling machine's capacity indicates the number of beans it can efficiently shell within a specific time frame, usually expressed in kilograms per hour (kg/h). This capacity directly correlates to the machine's size and power requirements. Larger, more powerful machines typically have higher capacities.

Power requirements for bean sheller machines vary based on their type and size. Electric machines usually specify their wattage or kilowatt (kW) rating, indicating the power needed to operate. For instance, a small electric bean sheller might require around 0.5 kW, whereas larger machines could need 2 kW or more. Portable bean sheller machines often have built-in motors to ensure seamless integration and mobility, eliminating the need for external power sources.

On the other hand, pneumatic or air-powered machines indicate their air pressure requirements, measured in pounds per square inch (PSI). These machines may require a specific air compressor setup to provide the necessary pressure for shelling beans effectively. For instance, a pneumatic bean sheller might need 90 PSI to function optimally.

The shelling efficiency of a bean shelling machine indicates how many beans are successfully shelled and separated from their pods compared to the total number of beans fed into the machine. This efficiency is crucial for minimizing waste and ensuring a high product yield. It depends on the design of the machine, including the size and shape of the shelling mechanism, as well as the training of operators.

Proper maintenance of the bean sheller is essential for smooth operation, exceptional performance, and extended lifespan. Cleaning the machine is crucial to prevent any residue buildup that could impact further shelling operations. Regularly removing any leftover beans, pods, or shelling residue and thoroughly cleaning the parts with water and mild detergent is recommended. Moreover, it is essential to dry the machine completely before storing it to avoid any rust or mold growth.

In addition, lubricating the moving parts is also essential to ensure smooth operation and prolong the lifespan of the machine. Users should apply food-grade lubricant to chains, gears, and bearings regularly. It is also essential to calibrate the shelling mechanism periodically to maintain optimal shelling efficiency. Shelling settings, such as the spacing between the shelling plates and the pressure applied, should be adjusted according to the type and size of the beans being shelled.

Usage scenarios of a bean shelling machine

• Small-scale farms and home consumption:

  One of the main uses of a bean sheller machine is on small-scale farms or for home use. On these kinds of farms or for personal use, a compact bean sheller is used because it has the benefit of being affordable, practical, and efficient for occasional use. It lets the operator remove beans from different pods quickly and accurately. When this machine is used on small-scale farms, it can help improve productivity and save time compared to manual methods.

• Food processing industry:

  In contrast, the larger versions of the machine are used in commercial settings and the food processing industry. They have a big capacity and can handle many beans or peas at once efficiently and quickly. These commercial-scale bean sheller machines have strong builds and lasting materials to withstand heavy daily use. They are often coming equipped with many speed settings and removable parts to let operators take full control and change the machine to meet various needs when working with different products.

• Wholesale markets and retail packaging:

  In addition to farms and the food industry, bean sheller machines are also used in wholesale markets and retail packaging. Here, bean shellers with conveyor belts are practical. These models save time and increase efficiency. They can shell beans steadily, putting the shelled beans straight into containers or boxes ready for storage or sale. This kind of setup reduces the need for operators manually handling the beans, which speeds up the process from shelling to storage.

• Research and development laboratories:

  Finally, in the food science area, these machines are valuable tools for research and development labs. R&D labs investigating the properties of beans and how to improve processing methods use bean shelling machines to separate the beans accurately and quickly. The machines allow them to work efficiently so they can study the specific features of different types of beans.

How to choose bean sheller machines

When looking for the right bean shelling machine, it is important to identify the requirement first. Determine the kind of beans for which the machine is needed and the amount of capacity required. This will depend on whether the machine is to be used for domestic or commercial purposes. Once the requirement is determined, it is easier to shortlist the machines by their specifications.

Different beans require different mechanisms to separate them from their shells. By thoroughly studying the working mechanisms of the shortlisted machines and examining their advantages and drawbacks, buyers will be ready to make the choice confidently.

The following specifications will help buyers make the right choices:

• Adjustable shelling mechanisms: Some machines have adjustable shelling mechanisms, which allow them to be versatile and adaptable to different types of beans and sizes. These kinds of machines are worth investing in because they can be used for different beans without incurring extra costs.
• Fine-tuned separation processes: Certain models of bean sheller machines have the ability to fine-tuned separation processes. Such machines ensure that only the shelled beans are separated, minimizing the risk of damaging beans that are still in their shells. This is an important feature to look for in shelling machines.
• Energy-efficient operations: The energy consumption of bean sheller machines can vary significantly from model to model. It is best to choose machines that offer energy-efficient operations. Consider the energy requirement during operation, including the motor power, along with the capacity so that energy consumption can be calculated.
• Easy to operate: The user interface is also an important thing to consider while choosing a bean shelling machine. An easy-to-use machine helps in smooth operation and minimizes the need for technical assistance.
• Disassembly for cleaning and maintenance: One of the important features of industrial and commercial machinery is the ability to clean and maintain them easily. Machines that can be disassembled for cleaning and maintenance will ensure hygiene and prevent the build-up of any kind of residue in the machine.
• Detailed product specifications: When purchasing bean shelling machines, it is always a good idea to check the product specifications. These include the shelling capacity, dimensions and weight, power requirements, the materials from which the machine is made, and so on.
