Types of Grading Sorting Machine
Optical sorting machines
Optical sorting machines use cameras and sensors to inspect food products. These machines are designed to detect and remove defective items based on color, shape, size, and other visual characteristics.
Weight grading machines
Weight grading machines sort products based on their weight. These machines use scales or weigh-in-motion systems to categorize products into different weight classes.
Size grading machines
Size grading machines classify products based on their dimensions (length, width, diameter). These machines often use rollers, screens, or sieves to separate items into size categories.
X-ray sorting machines
X-ray sorting machines use X-ray technology to inspect the internal and external qualities of food products. They are capable of detecting foreign objects, such as metal, glass, and bone fragments, as well as evaluating product density and structure.
Laser sorting machines
Laser sorting machines use laser beams to analyze the surface of food products. These machines can detect color, shape, and surface defects with high precision.
Mechanical grading machines
Mechanical grading machines use physical mechanisms such as rollers, conveyors, and vibrating screens to sort products. These machines often rely on the physical properties of the items, such as size, shape, and weight.
Advantages of Grading Sorting Machine
Speed:
Automation allows you to grade your produce much faster than humans. This increases efficiency and reduces labor costs.
Accuracy:
Grading technology measure and grade fruits and vegetables with higher accuracy than human graders. This leads to better quality control.
Consistency:
Automated grading systems grade your produce exactly like the parameters tell them to. They reduce human error and ensure consistent grading across all different quality characteristics.
Customization:
Automated grading technology can be customized to meet specific grading criteria and standards. This ensures you to sort your fresh produce exactly according to your clients wishes.
Data collection:
Grading software collects data on each fruit and vegetable that passes through the system. It provides valuable information on yield, size, quality and other data.
Sorting/Diversion Mechanism:
Paddles, air jets, tilting trays, drop chutes, or belt diverters that physically move the fruit to the correct output lane.
Singulation system:
Crucial step ensuring fruits are separated and presented individually for accurate measurement (rollers, belts, flumes).
Sizing mechanism:
Rollers, cups, weigh cells, or camera stations.
Control system:
Electronics and software that interpret measurements and control sorting actuators.
Infeed system:
Gently feeds fruit onto the sorting mechanism (e.g., vibrating table, conveyor with singulators).
Output lanes/bins:
Collection points for the different size grades.
User interface (HMI):
Screen for operators to set parameters, monitor performance, and diagnose issues.
