We know that the current market mainly consists of track type color sorting machines and slide type color sorting machines. Which one is more efficient and suitable for use? This will be explained in the following text.
Compared to traditional slide type color selection machines, track type color selection machines have advantages such as high color selection accuracy, minimal damage, high output, and direct packaging after selection. They are increasingly recognized and accepted by customers of color selection machines, and their market share is constantly expanding.
One A Brief Analysis of the Applicable Scope of Slide Type Color Sorters and Track Type Color Sorters
On the other hand, due to the fact that the slide of the slide type color sorting machine is designed according to the shape and size of the product, it is suitable for regular materials such as rice and wheat. For materials with significant differences in shape and size such as peanuts, plastics, ores, and tea, the color sorting effect is not ideal. With the continuous enrichment of material types in the market and the increasing demand for color selection, slide color selection machines have gradually become unsuitable for the development trend of the color selection industry. The track color sorter is different, it is suitable for color selection of various materials.
II What is a slide type color sorter?
The slide type color sorter uses gravity to make materials slide at high speed along the slide. Some materials cannot slide at a constant speed or have up and down jumping during the sliding process, resulting in low color selection accuracy.
There are two important steps in the operation of a color sorter, namely optical imaging and nozzle. The main function of optical imaging is to identify materials, while nozzles mainly remove materials based on identification. Inside the entire machine, there is a distance of about 10cm between the optical imaging point and the nozzle position, so there needs to be a fixed delay and a stable running trajectory for the material from the discovered position to the nozzle position. The material fluctuates up and down on the slide machine, causing it to not run at a constant speed on the slide. If the speed is not consistent, the nozzle delay will also be inconsistent, which will cause the nozzle to move in advance or delay, ultimately leading to a decrease in color selection accuracy.
In addition, the up and down jumping of the material actually affects the distance from the material to the optical imaging lens, causing imaging blur. The up and down jumping of materials can also affect the distance between the material and the nozzle. Therefore, when the material is too far away from the nozzle, the force of the nozzle on the material will weaken, thereby reducing the color selection accuracy.
III What is a track color sorter?
The track color sorter relies on the conveyor of tracks to transport materials to the sorting area. During this process, the materials run at a constant speed and remain relatively stationary, which can effectively maintain a fixed delay and stable running trajectory. This maximizes the accuracy of color selection.
When the slide type color sorter is running, the material is continuously accelerated from top to bottom. Even after the color selection is completed, the material will still be accelerated for a period of time and distance, which will increase the damage to the material and lead to a high rate of damage.
However, the track color sorter does not have this defect. The material moves horizontally on the track, flies and falls flat, and there is no problem of excessive acceleration of the material. The damage to the material is relatively minor and small. For materials such as peanuts, peanuts, peeled peanuts, garlic, and tea that require high damage rates, customer on-site verification has shown significant results with very low damage rates.
In terms of color selection output, the speed of the track color selection machine is controllable and the output can be adjusted. The specific design is based on the actual production of the customer. The structure, speed, and output of the chute color sorter are fixed.
Compared to slide machines, track color sorting machines require some moving parts and have a relatively complex structure, so their cost is relatively high. However, overall comparison shows that the economic benefits of tracked color sorting machines far outweigh the cost investment.
4 Summary:
Compared to slide color selection machines, track color selection machines offer a wide range of material options, high color selection accuracy, minimal damage, high output, and low take out ratio. In short, the cost-effectiveness of track color selection machines is much higher than that of traditional slide color selection machines. They perfectly achieve the screening function and can use mechanization to select high-quality products, which greatly promotes the development of agricultural mechanization and gradually replaces slide color selection machines in the market, becoming the first choice for color selection customers.
