The fruit grader moves on the inner or outer surface of the roller when it works. Because the relative motion between the lemon and the roller surface is small, it is not easy for the lemon to collide with each other, and the damage is very small. This method is suitable for the classification of spherical and nearly spherical materials. It is easy to finish in structure, low in cost, high in classification accuracy, and high in efficiency. It is widely used at home and abroad.

 

 

The important part of the drum classifier is the cylindrical screen with an inclination of about 3 ~ 5 degrees. The screen mesh is made of stainless steel plate, and the aperture is from the high end of the cylindrical screen to the low end. With the rotation of the cylinder screen, the lemon gradually leaks out from the sieve hole from small to large, and the extra large lemon rolls out from the cylinder screen.

 

 

 

The classifier is composed of progressive feeder and 4-barrel 5-stage classifier. Progressive feeder is automatic progressive, and the average feeding is achieved through automatic rotation of roller. 4-barrel 5-stage classifier is sorted according to the diameter of lemon. The machine foot is equipped with universal casters, which is easy to move and operate. The machine power is 1.1kw.

 

The working principle of the fruit classifier is: after the picked lemon is poured into the fruit washing tank, the control equipment of the machine is initiated, so that the automatic classification can be completed after the cleaning, transportation, cleaning, transportation, multi row conversion to single column, classification recognition and offline classification operation. Therefore, the secondary machine includes the following parts: Lemon washing trough, washing and escorting machine, lemon washing machine, waxing machine, lemon wax dryer, transportation equipment, single line mechanism of multi row fruit consumption line, fruit grade identification equipment, offline lemon grading structure.

 

Fruit grader uses: fruit with leaves, citrus, pear, apple, peach, big green jujube, pomegranate, mangosteen, tomato, lemon, mango and other round fruits and vegetables.
