Onion Taring Line

An onion taring line developed by RMA-Techniek for weighing, top tailing and inspecting onions.

RMA-Techniek has built up a lot of experience with onion inspections through the years. We can help you with this by developing a complete onion taring line from weighing onions to top tailing and inspecting.

Top tailer

The sample is thrown onto the top tailer by means of a conveyor belt. The onions fall onto the rollers of the top tailer. The 'tail' of the onion will be pinched off by the counter-rotating rollers.

To ensure that onions do not remain on the rollers, the machine is equipped with an emptying mechanism. This mechanism consists of a number of rubber flaps that rotate over the onions by means of a chain drive. This way the onions are brought to the end of the top tailer where they are further transported in the taring line.

Space is provided under the top tailer to place a box. A tarpaulin is provided to prevent dust from still being released between the box and the machine.

Weighing platform

The sample will be weighed by means of the weighing platform. The box can be placed on the intended platform, and the weight can be read on the screen. After the weight has been determined, the box can be emptied into the hopper. The funnel is designed in such a way that some of the dust and small debris is already filtered out of the sample.

Inspection table

When the onions are top tailed, they end up on the inspection table. The inspection table consists of a conveyor belt over which the onions are transported, a row of trays where the different sizes can be sorted, an input screen, a printer and a weighing platform where the remaining onions are weighed.

The entire line consists of:
