Bean sorting grading machine

Types of bean sorting grading machines

A bean sorting grading machine is an essential piece of equipment used to segregate beans based on different parameters, including size, color, weight, air drag, acoustic signature, shape, and length. Distinguishing beans based on these features is crucial for food processing companies, as it ensures that only the right type of beans make it through to the cooking or canning facility.

Generally, bean sorting machines can be classified into two broad categories: sieving machines and color sorters. Sieving machines use mesh or screens with different diameters to let through only specific beans while trapping others. Typically, sieving machines are low-tech machines that do not require a lot of energy to operate. Beans that fall through the sieve are further processed, while those that do not are discarded.

The Color sorting bean grading machine sorts beans based on color and is usually equipped with a high-resolution camera and artificial intelligence to tell the difference between good and bad beans. Recent advancements in technology have made it possible for machines to distinguish between subtle differences in color. Additionally, modern machines are capable of sorting beans based on size and shape, letting through only the right ones to the processing facility. Usually, color sorting machines are automated and have higher processing capacities than sieving machines. They are linked to hoppers that feed beans at high volumes, and they discharge sorted beans into collection bins. Depending on the level of automation and technology, these machines can be quite expensive.

Colour sorting machines can further be divided into:

• CCTV-Based Sorting Machines: These machines utilize closed-circuit television technology to visually inspect and sort beans based on color differences. A set of cameras captures images of the beans, and computer algorithms analyze the images to identify and separate beans of different colors.
• CCD (Charge-Coupled Device) Camera Sorting Machines: Beans are captured by CCD cameras in these machines, which convert the visual information into electronic signals. The signals are then processed by sorting software that classifies the beans based on color.
• Laser Color Sensor Sorting Machines: Using laser sensors, these machines detect color variations in beans. The lasers emit light that interacts with the beans, and the sensors measure the light's reflection and colorimetry. The data is then analyzed to determine the bean's color, and the beans are sorted accordingly.
• Hyperspectral Imaging Technology: HSI (Hyperspectral Imaging) color sorting machines are advanced devices that use hyperspectral imaging to sort beans. These machines capture detailed spectral information about the beans, allowing for a more precise analysis of their chemical composition and color.

Overall, color-sorting machines operate using a similar mechanism. An array of sensors is used to recognize good and bad beans, and a jet of air is released to blow the unwanted beans, which are then collected in a separate container. The desired beans are further processed.

Specifications and maintenance of bean sorting grading machines

Specifications

• Sorting materials: Beans, such as red beans, green beans, yellow beans, etc.; also can be applied to other similar grains, such as raisin and frozen berry selection. The beans sorting machine may require specific adjustments or configurations to accommodate different types of beans.
• Machine structure: The architecture of a bean sorting machine typically involves several key components that work together to facilitate the sorting process. The main components might include a feeding system, a conveying system, a sorting mechanism, a collecting system, and an overall machine structure with frames and support.
• Sorting Methods: Commonly employed sorting approaches, such as size-based, color-based, shape-based, or optical sorting, which utilize advanced technologies such as machine learning and image recognition.
• Machine dimensions: Such as the weight, size, and capacity. For example, a small bean grading machine's length could be around 1 meter, the width 0.5 meters, and the height 1.2 meters. Large machines may have longer pipeline threads, such as 6.5 meters, and about 1.2 meters in width and 2.3 meters in height.
• Power Supply: Such as voltage, frequency, current, etc. For instance, some machines require a three-phase supply with 0.75kw.

Maintenance tips

• Cleaning: Regular cleaning is a crucial step in the grading machine's maintenance, which helps prevent the buildup of debris and dirt. One can use a soft brush or a vacuum cleaner to remove loose material.
• Lubrication: Lubrication is critical in ensuring the smooth operation of moving parts of the grading machine, such as bearings. Users can apply a small quantity of lubricant to moving components that are exposed to friction.
• Inspection: Conducting regular inspections is vital for identifying signs of damage or wear. Check all machine parts, including belts, bearings, and blades, in look for deformities or damages. Also, ensure the fasteners are securely covered.
• Calibration: Grad bean machines include complex grading systems that should be regularly adjusted to maintain accuracy. Follow the manufacturers' instructions for proper calibration, and apply the suggested settings, and periodically check the calibration results.
• Dust Control: Such as using an exhaust fan to reduce dust pollution produced during the grading process. It can be achieved by using a vacuum cleaner or a dust collector.
• Check Electrical Components: By focusing on electrical components, such as wires and connectors, checking for damages, loose links, and signs of corrosion to ensure secure connections and proper insulation.
• Follow Manufacturers' Guidelines: Each grading machine is unique, and their maintenance requirements may vary. Users should follow the specific maintenance recommendations and instructions provided by the manufacturers to ensure optimal performance and longevity of the machines.

Scenarios of using a bean sorting and grading machine

• Food manufacturing and processing companies

  These companies usually have large amounts of beans to sort. They will use industrial-scale machines with large hoppers to handle input at that capacity. Beans of all varieties are typically run through machines to remove impurities for the safety and satisfaction of customers.

• Farming operations

  Bean grading machines are invaluable tools for farmers who grow beans as their main crops or entire business model. Farmers with small to medium-sized bean-growing operations prefer portable machines they can easily move from field to field. Grading by size and color helps determine what can be sold at farmer's markets or directly to restaurants or grocers.

• Exporting and importing companies

  These companies run diverse, large-scale bean sorting machines to meet international standards when exporting beans to foreign markets. Grading determines the price and what countries beans can be exported to. Along with the financial aspect, it is essential to follow all international laws and guidelines.

• Wholesale suppliers

  Wholesale distributors need efficient and accurate sorting machines to maintain their supply chains. The goal is to meet retailer demands and avoid costly miscommunications and excess inventory.

• Small-scale businesses

  Local coffee shops and small cafes are examples of businesses that have limited inventories but still need to ensure the beans they serve to customers are properly sorted and graded. Small bean grading machines are sufficient for such businesses and help keep costs low while maintaining quality.
