By covering the surface of your cooking vessel with these polypropylene balls, a reduction in water evaporation of up to 90% can be achieved, crucial when cooking using a thermal circulator for long periods of time. Undesired effects of light and odours are also significantly reduced.
The polypropylene balls are lightweight with a very hard and smooth surface which also helps prevent bacteria and chemical corrosion. The steam trapping balls allow you to cook without a cover with minimal heat loss and evaporation.
Each pack contains 100 balls of 20mm diameter.
