Project Description

Onion topper A2 with Pregrader

Onion topper

Categorie: Cleaning

The Allround Onion toppers are designed to top the ‘tail’ of onions. This is done by rotating knifes under vibrating sieves. The vibrating sieves causes the ‘tail’ of the onions to fall through the sieves, and is then cut off by the knife. The sieves of the machines are very easy to change because of the ‘quick lock’ system.

The Onion toppers are designed to be extremely produce friendly, and safe to use. Knives and propeller must be cleaned daily.

The pre-grader of the A1 onion topper will cause the undersize produce, and small waste, to fall through. This makes sure the undersize onions do not enter the machine, which creates dust and causes you to have to clean the machine more often

Frequency inverter knife motor

Extra set of knifes for one propellor

Frequency inverter on the sieve motor

In some cases, it is needed that the sieves of the machine do not shake at full speed. This might occur when the produce is very delicate. In most cases however it is best to have the motor run at full speed.

Machine on wheels

In some cases it is needed to be able to transport the onion topper. Allround VP is able to fit the machine with wheels.
