Extraction plant for potato and onion processor
At a large potato and onion processing and packaging company in Belgium, Meconaf recently installed an extraction system. The installation includes two cyclone systems, a windshifting system, diverter valves, booster fan and many meters of piping.
Windshifting installation
In the first place, at the beginning of the processing line, at the supply of the potatoes or onions, a windshifting installation is installed. Windshifting is a combination of blowing and suction in one. With this we realize that we immediately separate large amounts of sheets and dust from the product stream.
Changeover valves exhaust system
Furthermore, by switching with valves, the plant can provide extraction for both potato processing and onion processing. Purely because they are two different processing lines. In fact, the main tube inside splits to separate suction lines. Depending on the product (potato or onion), one then opens the appropriate suction line by means of the switching valve.
In this project, because of the required capacity, two cyclones were chosen. One for the packaging area and windshifting and one for the two processing lines.
Booster fan
A booster fan was also installed in the piping to bridge the large distance between the packaging department and the cyclone plant. To illustrate, the piping here is about 80 meters. The booster fan is placed as a kind of tool, to ensure that the air speed remains high enough to carry away all the dust and sheets.
In short, Meconaf installed a versatile extraction system at the potato and onion processor.
