Why should we use an efficient egg grader?

All kinds of eggs like duck eggs, and goose eggs are nutritious foods that we often eat in our daily lives, so eggs are usually sold well in the market. However, eggs are extremely fragile products, and eggs are often broken and wasted in the process of egg collecting and classifying. Manual egg classification is inefficient and takes a long time. Therefore, the use of a fully automatic egg grading machine to sort out and collect eggs is very important for the majority of egg distributors and egg processing plants. In addition to the grading of eggs, there are other egg processing, such as egg cleaning, egg coding, and other processing, so that eggs are more clean and hygienic and guaranteed when they are purchased by consumers.

The egg grading processing:

  1. The worker manually places the eggs on the conveyor belt. There are neatly arranged individual egg trays on the conveyor belt so that the eggs are not easy to slide and break.
  2. The conveyor belt will transfer the eggs to the part where the light inspection device is installed. The light inspection device will continue to emit light, and the light will penetrate the eggs to detect the quality of the eggs. Workers can pick out broken eggs, embryo eggs, black eggs, moldy eggs, and so on.
  3. After light testing, good eggs will be sent to the grading system. The grading system is pre-defined into 5 to 7 grades according to the weight and size of the eggs. When the eggs pass through the sorting device in turn, eggs of different weights will fall into different channels, and eggs of the same weight will fall into the same channel.
  4. Finally, the worker manually collects the eggs from different channels into different egg trays.

Through the factory’s research on egg grading, it is found that when the egg grader is in operation, it is more troublesome to place eggs, and you must be very careful, otherwise the eggs will be easily broken. Therefore, in the new version of the egg grader, the eggs can be placed on the machine by the egg suction machine, which saves a lot of time.

How to check the egg sorting machine before starting?

  1. It is strictly forbidden to put any sundries on all transmission chains of machinery and equipment. If so, it must be cleaned up before starting.
  2. Check whether the egg conveyor track chain bar is And checks the chain of each part of the machine for tripping.
  3. Check and clean the automatic weighing system to check if the knob in the package head is in place (open the machine cover at the top of the package head and check if the protruding metal rods on both sides of the black knob are fully inserted into the groove).
  4. Check that the compressed air valve is open (should keep it open normally, if it is off, the green handle is level with the ground, turn the green handle clockwise 90 to make it perpendicular to the ground).
