About Schrauwen trading & engineering
Schrauwen trading & engineering NV has specialized since 1983 in the supplementary dosing of liquids in the production and treatment of animal feed, pet food, premixes, grain and fertilizers. The company from Turnhout (Belgium) designs and manufactures its own systems and components based on the specific requirements of these industries, including the Micro Volume Sprayer (MVS Coater) for coating pellets after pelleting (post pelleting) and the SMOG/NT-Atomizer for atomizing liquids directly in the mixer. The MVS uses CDA spraying technology (Controlled Droplet Application) with three stacked rotating discs and produces uniformly sized droplets for homogeneous distribution of the smallest liquid quantities onto the pellets. The portfolio also includes heated molasses day tanks, continuous weighing belts, mass flow meters, pumps, dosing pumps, liquid filters, electropneumatic valves, storage tanks, prefabricated liquid cabinets and electrical controls. Schrauwen offers complete projects with engineering, installation and service; according to the company, more than 200 MVS coaters are in operation, together coating over 5 million tonnes per year.

Application media and processes
Micro Volume Sprayer (CDA spray system)
Coating of pellets and crumbs with enzymes, phytase, fat, soybean oil, fatty acids, probiotics and flavours in the post-pelleting process.
SMOG/NT-Atomizer (centrifugal spray system)
Atomizes liquids of various viscosities and densities, including those with solids (smallest liquid passage 12 mm), directly in the batch or continuous mixer.
Heated molasses day tanks
Stainless steel tanks with 500 to 3000 litres capacity, heated to max. 50 °C via a double bottom with thermal oil and perforated mixing inserts.
Continuous weighing belts
Gravimetric detection of the pellet flow for precise liquid dosing.
Mass flow meters
Measurement of the liquid flow for exact dosing onto pellets or into mixers.
Top coating with powder-oil suspensions
Application of powders such as probiotics in oil suspension onto pellets.
