ÖNSA Machine-manufactured milk storage tanks are designed to preserve the quality, nutritional value, and hygienic integrity of fresh milk for extended periods. Manufactured from AISI 304 and AISI 316 quality stainless steel in full compliance with food safety standards (HACCP), our tanks offer professional solutions for every scale, from dairies to industrial milk processing plants.

Technical Specifications

Capacity: Flexible production options from 500 litres to 100,000 litres.

Construction: Vertical or horizontal cylindrical body, conical base design for complete drainage.

Surface Treatment: Smooth polishing (mirror finish) on internal surfaces, matt or Scotch Brite coating on external surfaces.

Equipment: Sample valve, vent, top manhole cover and stainless steel adjustable feet.

Maximum Hygiene and Heat Retention Standards

Surface quality and insulation are the most critical factors in preventing product spoilage during milk storage. Our tanks are equipped with high-density insulation layers that maintain a constant milk temperature and a smooth surface structure that does not harbour bacteria.

Key Functional Features

High-Quality Material: Certified AISI 304 or AISI 316 grade corrosion-resistant stainless steel.

Advanced Insulation: Polyurethane or rock wool insulation that prevents the milk from being affected by the outside ambient temperature.

Homogeneous Mixing: A gentle mixing system that prevents the fat structure of the milk from breaking down and distributes the temperature evenly throughout the product.
