Various uses of garlic color sorter in agriculture
As an economic crop, garlic is widely grown in many parts of the world. Garlic is divided into purple garlic and white garlic. Purple garlic has a strong flavor and is generally found in the north; white garlic has a mild flavor and is eaten more often in the south. China's garlic planting and processing industry is also developing rapidly, but the mechanization of garlic production is still in its infancy. It is mainly manual, with low production efficiency and high work intensity. affect the development of the industry.
1. The application of color sorter technology in garlic cultivation.
In order to solve the problems encountered in garlic planting, picking and classification, color sorters are applied to the garlic industry. The color sorter plays an important role in the whole production and harvesting cycle of garlic.
First of all, the color sorter provides assistance for the grading of garlic seeds. According to the article "research status and prospect of garlic seed classifier"（https://xueshu.baidu.com/usercenter/paper/show?paperid=115602v08w5v00p0wj590gx0fn681038） published by "Journal of Chinese Agriculture Mechanization": the mechanized classification of garlic seed not only requires the classification rate, but also the graded garlic seeds mainly In addition to the grading rate, the graded garlic seeds are mainly used for planting, and they are also required to meet the agronomic requirements of garlic planting, with intact outer skin and no damage. The development of optoelectronic technology can do this. For example, the garlic color sorter produced by GroTech can comprehensively use new technologies such as modern optics, electronics and biology to detect the appearance, internal quality and other aspects of the material, and perform automatic classification and rejection.
Secondly, garlic color sorter is also starting to be used in the process of harvesting. Anyone who has grown garlic knows that garlic tends to wither after being left for a long time. And consumers will choose garlic that is large, neat, and firm when choosing garlic. Weigh it by hand and feel heavyweight, garlic cloves are not sprouted, odorless, and dry. Manual selection of garlic is inefficient, time-consuming, and labor-intensive, and cannot meet the production demand. With the rapid development of science and technology, garlic rice color selection began to be artificially intelligent. It can effectively sort out peeled and unpeeled; garlic with different colors and shapes after peeling; garlic with the rod, garlic with skin, garlic with the dark scar, etc.
Third, the garlic color sorter can be widely used in scientific research, helping agricultural researchers to improve the industrial process of garlic planting and harvesting, and improve the economic benefits of garlic planting.The "Training Toolkit, Module 2: Seed processing equipment", published by the Food and Agriculture Organization of the United Nations, describes the use of color sorters in seed selection.“The colour-sorting machine – or optical sorting machine – is a sophisticated piece of equipment that separates seeds according to colour or light reflection. The seed is fed into a hopper on top of the machine and guided into thin lines or channels of seed that pass through a dark chamber. A special light bulb illuminates the seed flow and reads the colour of individual seeds. When an impurity is detected, a shot of high-pressured air diverts it from the seed flow.”（http://www.fao.org/3/i6396e/I6396E.pdf）
2. What is a garlic color sorter?
Garlic color sorter is a kind of belt type color sorter. The color sorter can be divided into chute-type color sorter and belt-type color sorter. The chute-type color sorter uses the action of gravity to let the material slide along the chute to the sorting area. During the sliding process of the material, it is inevitable that collision and friction. The belt-type color sorter sends the material from one port (into the hopper) to the other end of the outlet through the crawler, and the process is relatively stable. This can greatly reduce the breakage rate of the material. This satisfies the need for color sorting of garlic seeds. Garlic is very brittle and can be easily damaged during the color selection process. It is recommended to choose a belt type color sorter machine,。The garlic color sorter developed by GroTech is mainly for fragile materials to improve the degree of finished materials and reduce the damage rate.
3. Ten advantages of garlic color sorter
（1）The belt-type soft conveying system has lower drop, low broken rate, and High productivity applicable to various materials.
（2） High flexibility, applicable to a wider range of materials, can accurately set the operation parameters according to the moving track of specific materials; which makes the machine multifunctional and high value-added.
（3）Powerful Operation System, various sorting modes and automatic memory function, set sorting system once for repeated materials, best sorting results are acquired easily.
（4）The belt color sorter is more suitable for combining artificial intelligence technology (deep learning algorithm), because the deep learning algorithm needs to set aside a certain amount of time for identifying materials, and the space required for the identification area is greater.
（5） Double-layer belt system, for materials with a high impurity for example plastic, can complete sorting at one time.
（6）belt color sorter for specific materials can be specially customized, such as the belt bed structure design can be optimized to spill material processing, to prevent material to the internal belt and roller scratches.
（7） Leading LED light source technology. High efficiency, long service life, strong anti-interference ability, and lower cost。
（8） Leading intelligent shape functions can effectively detect different sizes and shapes. Optional NIR function can detect and remove various malignant impurities.
（9）Stainless steel body construction， Separable body design for quick belt change。
（10）Belt color sorter supports a variety of ways to clear the ash combination, especially for easy to wear the material light using high-pressure gas clearing ash, reducing glass wear, to ensure recognition rate.
4. Precautions for the use of garlic color sorter.
（1） Garlic may be damaged during the molting process, and some juice will flow out. The color selection machine works for a long time, and the vibrating feeder becomes very dirty, which affects the color selection effect.
（2） During the working process, because the garlic is damaged, the juice will splash on the glass, which will affect the color selection of the color sorter. GroTech has introduced the innovation of widening the glass to minimise the influence of juice on the effect of colour selection.
（3） To maintain the garlic color sorter, dry garlic is best cleaned every 2-3 days, and wet garlic is cleaned once a day.
