How many mixing tanks do I need for a beverage line with multiple flavours?

A minimum of two mixing tanks per product type is recommended for a continuous production operation: one tank is being filled and blended while the other feeds the filler or pasteuriser. This two-tank (buffer tank) arrangement prevents the filler from waiting for the blending cycle to complete. For a multi-flavour operation, the number of tanks depends on the changeover frequency and whether tanks are dedicated to specific flavour groups or shared. Shared tanks require thorough CIP between flavour changeovers — a validated CIP cycle and allergen changeover procedure if any flavour ingredients contain allergens. Stainless steel tanks are easily CIP-cleaned, but the required CIP time and verification method must be established for your specific product range.

What surface finish standard is required for food-grade beverage mixing tanks?

For food-grade beverage mixing tanks, the internal product contact surface finish is typically specified as Ra ≤ 0.8 micron (approximately 32 microinch Ra) or better. A smoother surface (Ra ≤ 0.4 micron) is required for dairy and other hygiene-critical applications. The Ra (roughness average) specification prevents microbial harbouring in surface defects. All welds on internal surfaces should be fully welded and ground smooth. Connections and fittings should be to hygienic design standards (DIN 11851, SMS, or TriClamp/TriClover). Ask the supplier to provide surface finish measurement certificates (profilometer readings) for the vessel before acceptance.

Beverage mixing tanks — design and specification

Beverage mixing tanks are stainless steel agitated vessels used in beverage plants for syrup preparation, beverage blending (water + syrup + acid + flavour mixing before carbonation or filling), ingredient hydration, and intermediate storage. Standard design features for beverage mixing tanks include: 316L stainless steel product contact surfaces (to prevent corrosion from acidic beverage ingredients — citric acid, phosphoric acid, ascorbic acid); Ra ≤ 0.8 micron (32 Ra microinch) internal surface finish to meet food-grade hygiene standards; CIP (clean-in-place) connections — at minimum a CIP supply nozzle, CIP return, and drain; top-mounted agitator sized for the product viscosity (most beverage syrups are low to medium viscosity — turbine, propeller, or sweep agitator are standard); jacket (for hot syrup preparation where sugar is dissolved at elevated temperature, or for temperature-sensitive flavour blending); heating and cooling connections; temperature sensor; and a vent filter. Beverage mixing tanks are typically operated in a batch blending mode: ingredients are added in sequence, blended to homogeneity, then transferred to the filler feed tank or pasteuriser.
