The onions harvested in nature will show different shapes; but the onions we see in the supermarket are uniform in size, neat and look very comfortable. Because these onions have been graded, after the onions are graded, different grades of onions can be priced separately, which greatly increases the added value of onions. As the main equipment for onion processing, the onion grading machine is deeply loved by the majority of processors. So what are the types of onion grading machines?
1.Roller grading machine
The roller grading machine rotates through rolling bearings, and pushes all the roller shafts of the grading bed to move forward in parallel, gradually increasing the center distance between the rollers to reach the corresponding size of the onion, so that the onion is separated from the rollers. The distance between the onions is dropped into the conveyor belt and sent out to achieve the purpose of grading the size of the onion. The outlet of the grading machine is directly filled and sealed by the bag filling device, and the grading is achieved in a cycle.
2. Air grading machine
The airflow classifier adopts advanced classifying rotor design, with high classifying efficiency and accurate cutting point. A multi-stage classification system is composed of multiple air-flow classifiers connected in series, which are divided into several particle size segments according to the particle size of the material.
3.Turntable weight grading machine
The weight grading machine uses dynamic weighing technology to detect the weight of onions. It can detect onions with different weights in continuous work and automatically classify them according to the set weight level. It can also automatically count and store onions. The weight grading system is the core part of the weight grading machine, which determines the detection accuracy and operation stability of the weight grading machine. The measuring range of the weight sensor determines the weighing size and scale of the weight grading machine. At the same time, the accuracy of the weight grading machine also affects the accuracy of the weight sorting machine.
