Application
The document describes the continuous preparation of ice cream mix with capacities ranging from 1,200 l/h to 14,000 l/h. The unit handles the entire preparation process, including high shear mixing, high pressure homogenization, HTST pasteurization, and delivery to aging tanks. It is suitable for high viscous ice cream products, those containing pulps, fruit pieces, flavors, fragrances, sorbets, and water ice.

Highlights
- Fully automated continuous production
- Powerful mixing with Tetra Pak® High Shear Mixer
- Production traceability and product safety system
- Hygienic design and sustainability focus
- Variable options including integrated CIP unit and external cooler
- Option for a third mixing tank for flexibility

Working Principle
Ingredients are mixed in a Tetra Pak® High Shear Mixer, which can be open or vacuum type. The mix is recirculated to ensure complete hydration. The Tetra Pak® Plate Heat Exchanger is used for heating and cooling, minimizing energy consumption. The unit is compact and divided into three parts: mixing tanks and mixer, unified frame with pasteurizer and HMI, and homogenizer.

Standard Material
The unit includes stainless steel mixing tanks with agitators, sample valves, level sensors, and CIP spray balls. The main frame contains a double strainer, balance tank, plate heat exchanger, pumps, hygienic valves, and an HMI panel. The homogenizer features automatic pressure release and remote pressure settings.

Automation Functions
- Automated PLC operated sequences for sterilization, mixing, pasteurization, circulation, emptying, cleaning, and CIP
- Automated pasteurization temperature control
- Automated flow diversion controlled by temperature sensors
- Differential pressure supervision

Optional Equipment
- Water recovery
- CIP dosing unit
- Rework/fat/sugar/fresh milk dosing inlets
- Extended holding time
- Control of CIP detergents with conductivity
- Connection to automatic powder handling units
- Control system Rockwell
- Product integrator with recipe management and parameter control

Technical Data
Capacities range from 1,200 l/h to 12,000 l/h. Dimensions vary by model, with recommended free space around the unit. The choice of mixer affects unit size.

Service Media Conditions
- Process water: 18-28°C
- Steam: 3 bar, saturated
- Compressed air: 6.0-6.5 bar
