Industrial tray washing machines

Clean propagation trays are essential for healthy products and higher profits. As a grower, of course you want to minimise the risk of contamination by bacteria, viruses and fungi, which makes good hygiene is very important.

Our expertise in manufacturing industrial tray washing machines is at your disposal

Cleaning with a Limex tray washing machine ensures that your industrial trays meet the strictest hygiene and food safety requirements. With our specialist knowledge and extensive experience, we can tailor our industrial tray washers specifically to your crops. This reduces the risk of contamination considerably and immediately results in less spoilage and higher net yields. After all, you’ve already made the investment into inputs such as energy, water, raw materials, seeds and labour;

Choosing Limex means choosing a sustainable solution. Our washing machines reduce water, energy and chemical consumption. The Limex tray washer removes organic soiling and eliminates contamination by bacteria, viruses and fungi. This results in less spoilage, and higher yields from the same investment in raw materials and labour.

Sinner’s Circle

Professor Sinner described and visualised the physical principle behind cleaning many years ago in his Sinner’s Circle. It explains how getting the balance between these factors right gives the best cleaning result. These factors are: mechanical action (water pressure and flow), time, temperature and chemical action. The four factors need to be balanced properly for maximum efficiency. Our engineers design the tray washers so they are perfectly balanced in accordance with the Sinner’s Circle principle.
