When I went to the supermarket, I found an interesting phenomenon in the fruit and vegetable area. When the fruits and vegetables were sufficient, some fruits and vegetables that had no other problems but were not good enough were often thrown aside until the fruits and vegetables became scarce, and some people would take them from A pile of fruit and vegetables with insufficient quality is selected. In this way, not only in the human group, but also in the food industry, the value of the face is also very important. Merchants are aware of this kind of psychology of people, using sorting equipment to strictly classify foods, reduce the ugly rate when selling, and let them enter deep processing factories to exert greater value. In this process, optical sorting equipment is indispensable.

Optical sorting equipment has greatly enriched the category of food sorting projects since it was introduced into the food sorting field. Most of the usual sorting equipment is used for the removal of foreign matter, size and weight. Since the optical sorting equipment, the sweetness, maturity, moisture content, slag rate, skin and internal flaws, biological characteristics, etc. They have become categories that can be sorted. In order to ensure high-end quality, the use of optical sorting equipment in the use of optical sorting equipment only selects five oranges that are superior in appearance, maturity and taste. There is also an optical sorting device for aflatoxins in nuts.

For optical sorting equipment, the light source is extremely important. Current optical sorting equipment sources include light-emitting diodes, infrared light, ultraviolet light, laser light, fluorescent light, and X-rays. Different lights will have different effects. Light-emitting diodes are used to remove defective products and impurities. Lights such as infrared rays and ultraviolet rays can be used for photography to distinguish the shape and color difference of the product. The laser can not only identify the structure of the product but also remove foreign matter. Color sorts foods; fluorescence uses natural fluorescence of some fruits and vegetables to remove foreign matter; X-rays can be used for packaged products, rejecting unqualified products by density index detection, and ensuring the safety of the final product... The evaluation criteria for food quality are constantly improving, and the optical sorting equipment is actually equipped with a more complex light source to achieve various requirements for sorting.

According to the online public information, the optical sorting equipment is suitable for a wide variety of foods. Local special agricultural products such as Minnan Navel Orange, Zhaotong Apple, Cangxi Red Heart Kiwi, and imported blueberry use optical sorting equipment as an important tool for sorting product grades to reduce the flow of non-conforming products to the market and enhance their brand image. As mentioned earlier, optical sorting equipment can also sort out food contaminated with aflatoxin, so nuts, seeds, peanuts and other dried fruits that are susceptible to aflatoxin contamination can be classified by optical sorting equipment. In addition, meat products such as meat and seafood can also be applied to optical sorting equipment. As for the packaged foods, x-ray sorting equipment can be used to eliminate the unqualified products... It can be said that the optical sorting equipment has been able to adapt to most food categories on the market.

In addition, in the food industry, cleaning is a part of the sorting equipment that cannot be ignored. Cleaning is divided into two aspects, one is the cleaning of the sorted food, and the other is the cleaning of the mechanical equipment itself. For the sorted food, the optical sorting equipment can be equipped with a variety of equipment such as feed pool, brush cleaning machine, drying tunnel, etc., which are well integrated into the food production line. In terms of cleaning the mechanical equipment itself, optical sorting equipment manufacturers have begun to provide intelligent cleaning functions for optical sorting equipment. According to reports, this optical sorting device equipped with intelligent cleaning function has its own monitoring device, which can automatically sense the cleanliness of the optical window and clean it. The cleaning process will not affect the sorting. This cleaning method is more intelligent and more efficient than regular cleaning.

For the time being, optical sorting equipment has adapted to people's further requirements for food quality, and there will be greater development potential in the future. Manufacturers of optical sorting equipment need to go deep into the market, gain insight into the further requirements for food sorting in the market, and timely reform and research equipment to seize the opportunity of food sorting.
