Ccd sorting

Types of CCD Sorting

A CCD food sorter uses a CCD camera to identify and classify food items according to particular criteria. The typical working process includes dropping the item on a moving belt while a camera takes images of each item in close intervals. After processing the image, the item is then classified according to the preset categories, and and item identified for rejection is either marked or physically removed from the conveyer at that point. A colour sorting machine works on a below-surface principle, using an arrangement of light sources and cameras to classify food products by colour.

A CCD sorter machine comes with many different types of sorting functionalities that are generally divided into two types:

• Functional sorting: This type of sorting is usually based on features like colour, shape, size, and maturity. It categorizes food items based on specific characteristics and distinguishes edible food from inedible food, that is not supposed to be consumed.
• Contaminant sorting: This kind of sorting differentiates between food particles that belong to a different category and should not be included in a specific food item. For example, foreign contaminants like stones, glass, or metal should be excluded from the sorted food product.

Apart from these two classifications, a CCD Sorting machine can also be classified based on its specific sorting methods:

• Colour sorting: A CCD colour sorter works by taking pictures of food items, usually using a CCD camera, and identifying and classifying them based on their colour. This is one of the most common sorting algorithms, and sorter applications are prevalent in the grain, nut, and vegetable processing industries.
• Size and shape sorting: These types of sorters use advanced imaging technology to measure the size and shape of an object. When the measurements are compared to preset parameters, the item is then classified. Usually, items that do not match the desired size and shape are excluded and identified as contaminants.
• Defect sorting: This method of sorting works on the basis of identifying defective food items, for example, rotten fruits, damaged vegetables, discolored grains, etc. It is usually helpful in enhancing the overall quality of the final sorted product and improving the yield.

Specification & Maintenance

Some of the most important CCD Sorting Machine specifications to highlight are as follows:

• Capacity:

  The number of items that the CCD food sorter can process at a specific time. This usually depends on the volume and speed of the sortation. For example, CCD sorters used for cereals can have 1000 to 3000 kg/h capacity, while those used for nuts can have 1500 to 4000 kg/h capacity.

• Optical Resolution:

  This is the minimum size and shape of an item that the CCD vision sorter can recognize. It usually varies between 2-5 pixels/mm. For example, to detect tiny foreign objects in food, a sorter may use a higher pixel resolution size.

• Camera:

  CCD sorters come with different types of cameras. These may be monochrome, grayscale, or color cameras. The traits or properties of an item that a camera captures also stems from the camera type. For example, a color camera can see the color differences of items.

• Boost System:

  Some CCD sorters come with a boost sorting system. This additional feature improves the total sorting performance of the machine. It works by increasing the speed of each item when they are ejected after sortation. The boost system is mainly used for sorters that handle ore and minerals.

• Reject Conveyor:

  This is the area where items that are not accepted by the sorter are placed. Items that are rejected will undergo further inspection and analysis. The conveyors used for CCD reject items vary in size and capacity based on what industry the sorter is used for.

Maintenance

With proper care and routine checkups, CCD food sorters can retain their sorting accuracy and efficiency. Here are some maintenance tips for these machines:

• Cleaning the Camera Lens: This should be done periodically to keep the optical performance at the peak. A lint-free wipe and cleaning solution should be used to do this.
• Regular Calibration: This is important to maintain the machine's sorting accuracy. The machines should be calibrated based on the guidelines provided by the manufacturer.
• Preventive Maintenance Programs: CCD sorters are vital processes in food production lines. Therefore, implementing a preventive maintenance program is very important. Doing this will help to identify issues before they deteriorate.
• Software Updates: The capabilities of the CCD sorter may improve with the software updates provided by the manufacturer. So, it is a great idea to stay up to date with them.

Applications of CCD Sorting

Some of the typical applications of CCD image sorting technology are as follows:

• Nut Sorting: One of the most common applications of CCD sorting technology is sorting various nuts, such as almonds, cashews, walnuts, and pistachios, based on different qualities like size, weight, brightness, shape, and other distinct features. CCD image sorting technology can efficiently categorize nuts with foreign material or those that do not meet the desired quality standards are removed from the final product.
• Fruit Sorting: CCD sorting technology is widely used in the fruit juice processing industry to sort fruits, such as apples, oranges, and berries, among others. In the fruit canning and freezing industry, too, fruits are sorted based on ripeness, color, size, and other factors. This ensures uniformity and quality in the final fruit product.
• Vegetable Sorting: Image sorting technology is also used to sort various vegetables like potatoes, carrots, leafy greens, and bell peppers, etc. The technology helps to remove discolored, misshapen, and decayed vegetables so that only quality produce is sent for further processing or distribution.
• Seeds and Grain Sorting: CCD sorting can also be used to separate and classify various seeds and grains, such as rice, wheat, coffee, cannabis, and cacao sorting, based on size, shape, and color. The technology helps enhance the purity, quality, and success rate of the seed and grain that is finally sorted and selected.
• Optical Detection of Defects: CCD sorting technology can detect various defects like cracks, blemishes, spots, and discoloration in a product to ensure quality. For example, tile sorting by CCD cameras can help classify good and defective tiles based on color, pattern, cracks, and other such features.
• Animal Sorting: The CCD immigration sorting system can also be used to categorize and separate different parts of animal carcasses based on color, size, and shape. For example, it can be used to identify and separate chicken parts like wings, thighs, and drumsticks. The technology can enhance yield and reduce wastage in poultry and meat processing plants.

How to choose a CCD sorting machine

Several kinds of CCD sorters are available, each with unique characteristics and capabilities. The devices use a chip-set that can sort various products and applications.

• Capacity and throughput:

  When selecting a CCD sorting machine for the requirements, it is essential to analyze its capacities. Consider the maximum capacity and throughput of the sorter. Take note of the volume that must be sorted and choose a sorter that can sort the required products in the hour while meeting production deadlines.

• Sizes, weights, and dimensions:

  CCD sorting machines come in various sizes. When choosing a sorter, it is essential to determine its physical weight and dimensions. The machine's capacity must accommodate the dimensions and weights of the products that need to be sorted. Consider whether it can be integrated into the existing production line.

• CCD camera technology:

  Consider the type of camera technology that should be used, which includes Color Camera Sorters, Near-infrared (NIR) Camera Sorters, Hyperspectral Camera CCD Sorters, and Multispectral Camera CCD Sorters. Each of these options is based on different wavelengths that identify specific material characteristics. Choose the camera that meets the requirement for material attributes.

• Other features:

  Depending on the product being sorted, faults that need to be identified, and the requirement for early detection in the production line, choose a CCD sorter that has the necessary software and hardware combination. Other essential features to consider are the type of material that needs to be sorted, the rejection mechanism required, the accuracy desired when sorting, and whether the sorter needs to be integrated into a packaging line.
