Abstract

The invention relates to post-harvest processing of onions and allows for increased productivity by improving the conditions for capturing the pen and separating the bulb from the pen. A pile of onions is fed in layers to the working body formed in pairs counter-rotating, imis oscillating rollers, while the oscillation frequency of the working body is set greater than the frequency of rotation of the rollers. Depending on the product to be processed, the oscillations dry out along or across or in both directions relative to the axis of rotation of the rollers. I zp f-ly, 1 ill.

This invention relates to post-harvest processing of onions.

The purpose of the invention is to increase productivity by improving the condition of capturing the pen and separating the bulb from the pen.

The drawing shows a diagram of the device 1dl separation of the pen from the bulbs. The method for separating the pen from the bulbs is as follows.

I A pile of onions with a feather is distributed in layers, in rows and directed at the working body formed by counter rotating rollers 1 with screw protrusions. The working body is brought into oscillatory motion by means of connecting rods 3 connected to the suspensions 2 connected to the eccentric shaft 4. The oscillation frequency of the working member is set higher than the frequency of rotation of the rollers. The frequency of rotation of the rollers may be, for example, 12 ... 19, and the oscillation frequency is 30 ... 38. The direction and frequency of oscillations for different heaps can vary: when processing a heap with small contents of a pen, in the longitudinal direction, with a large one in the transverse direction, and in case

Since the pile contains a large amount of wet and green feathers, oscillations are carried out in both directions relative to the axis of rotation of the rollers. When the rollers rotate and oscillate, the bulbs also get rotated and oscillated, the feather is drawn between the rollers, and due to the additional oscillation of the bulb, the process of its separation from the feather is enhanced.

Claims (2)

1. A method of separating the pen from the bulbs, including layer-by-layer feeding of the heap to the working body, formed by pairs of counter-rotating oscillating rollers, gripping and kneading the feather from the bulbs by the rollers, characterized in that, in order to increase productivity by improving the conditions of capturing the feather, the oscillation frequency of the working body set greater than the speed of the rollers. 2. A method according to claim 1, characterized in that the oscillations, depending on the product being processed, are carried out along or across or in both directions relative to the axis of rotation of the rollers.
