Milk and Food Tanks

Name: Milk and Food Tanks | Welltech®
Brand: Welltech®

Zero-roughness surfaces preventing bacterial growth, high-insulation polyurethane, and stainless engineering suitable for food safety.

Ultra-Hygienic Engineering (FDA/GMP)

The storage of milk, fruit juice, and delicate food products requires maximum hygiene. Welltech® milk tanks are designed to leave no blind spots (dead volume) inside. Weld seams are ground to a smoothness of Ra < 0.6 microns. Thus, there are no surfaces left for bacteria to cling to, and excellent cleaning is ensured thanks to integrated CIP (Clean-In-Place) balls.

Frequently Asked Questions

How well does the insulation in milk tanks maintain heat?

Thanks to the high-density (40-42 kg/m³) polyurethane insulation we use, even if the outside temperature is 30°C, the product temperature inside the tank increases by a maximum of 1°C in 24 hours.

How is the cleaning (CIP) of the tanks ensured?

Thanks to the 360° rotating CIP spraying balls placed at the top of the tanks, the pressurized washing liquid homogeneously contacts all inner surfaces of the tank, offering a zero bacteria guarantee.
