Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing, in particular to a round onion peeling processing line. BACKGROUND

[0002] Round onion generally refers to onion, which is one of the common vegetables and is also a regular guest of people's daily dishes. Various dishes are developed through onion. With the improvement of people's living standards, the demand for onion is increasing. However, the processing of commercial onion becomes a problem under the condition of increasing demand and use of onion. Large-scale production cannot use manual peeling, and manual peeling is easy to smoke eyes, time-consuming and laborious.

[0003] The existing onion peeling machine is to draw a knife mark on the surface of the onion, and then put it into the roller with a brush on the surface. The onion skin is rubbed off by the rotation of the roller. This way has limited peeling effect and is easy to remove incompletely, so it needs to be put into the equipment repeatedly for peeling, and the second time of putting into the equipment is easy to damage the surface of the peeled onion. Another kind of onion peeling machine is to peel the skin of the onion gradually by spraying high-pressure air with the knife mark as the center. Since the knife mark of the onion before peeling is usually 2-3 knives, after drawing the knife mark, the onion is sprayed by the high-pressure air above during the conveying process, and then the onion skin is blown off. The time of the onion in the conveying line is limited, and the onion is in a static state during the conveying process. When the orientation of the knife mark is downward, the effect of breaking the skin by the high-pressure air blowing on the surface of the onion is not good, and usually some skin remains on the surface of the onion. The above two kinds of existing onion peeling equipment cannot achieve the ideal peeling effect and are easy to damage the onion.

[0004] Therefore, it is particularly important to design a round onion peeling processing line to solve the above problems. SUMMARY
