Description

Technical Field

[0001] The invention relates to the technical field of vegetable processing, in particular to an onion peeling device. Background Art

[0002] Onions contain prostaglandin A, which can reduce peripheral vascular resistance and blood viscosity, and can be used to lower blood pressure, refresh the mind, relieve stress, and prevent colds. In addition, onions can remove oxygen free radicals in the body, enhance metabolism, resist aging, and prevent osteoporosis. They are a health food suitable for middle-aged and elderly people.

[0003] The use of peeling machines to peel a large number of onions can meet the high demand for onions. The current onion peeling machine only uses a single peeling mechanism, resulting in low onion peeling efficiency. At the same time, due to the presence of sulfide substances in onions, the volatilization of the substance can irritate the eyes and cause tears. When peeling a large number of onions, more sulfide substances will be produced. If they are not treated, they will be inhaled into the nasal cavity by the operator, thereby irritating the eyes and easily causing damage to the eyes and nasal mucosa, which urgently needs to be improved.

5. An onion peeling device, characterized in that: How it works: (1) Open the machine cover, place multiple layers of onions to be peeled on the No. 1 peeling mechanism at the bottom, insert the No. 2 peeling mechanism at the top through the sliding slot onto the slide rail in the machine housing, and place multiple layers of onions to be peeled on the No. 2 peeling mechanism; finally, insert the No. 1 peeling mechanism at the top through the sliding slot onto the slide rail in the machine housing; (2) Install the No. 1 eccentric wheel and the No. 2 eccentric wheel on the output shaft of the No. 1 motor and the No. 2 motor at the positions corresponding to the No. 1 peeling mechanism, the No. 2 peeling mechanism and the No. 1 peeling mechanism arranged above and below; ensure that the No. 1 eccentric wheel and the No. 2 eccentric wheel at the same horizontal position are installed in the same direction, and the No. 1 eccentric wheel and the No. 2 eccentric wheel arranged above and below are arranged in opposite directions; (3) Start the No. 1 motor and the No. 2 motor to drive the No. 1 eccentric wheel and the No. 2 eccentric wheel to knock the screen plate. Since the onions to be peeled are laid between the upper and lower adjacent screen plates, and the upper and lower peeling convex rings are arranged in contact with the onions to be peeled, when the No. 2 peeling mechanism and the No. 1 peeling mechanism at the upper and lower positions move left and right relative to each other, the peeling convex ring peels the onions; (4) While step (3) is being performed, the pump is started, and the waste gas containing sulfide generated during the peeling process is sucked into the deodorizing box through the deodorizing suction hopper. The onion skin sucked in during this process is intercepted by the filter screen and is manually taken out from the onion skin discharge port after a certain period of time. The sucked gas is adsorbed by the deodorizer in the deodorizing box and then discharged from the exhaust pipe; (5) When the onion skin is removed, open the blocking door and manually take the peeled onions out of the discharge slot.
