How it works
A controlled flow of ice cream mix or other ingredients is pumped into the freezing cylinder along with the desired amount of air. As the mixture passes through the cylinder, it is frozen by the refrigerant surrounding the cylinder, and air is incorporated by a dasher and beater. Stainless steel blades mounted on the dasher scrape the frozen mixture off the inside wall of the cylinder, and a second gear pump moves the ice cream forward for filling or extrusion.

Features
Space efficient design
How many litres product per m2
The selection of a highly compact motor and pulley system enable a narrow design, so it is possible to place several freezers side by side if needed. The internal piping is optimized to enhance space efficiency and serviceability – all of which results in an unusually high output for a footprint of only 1.72 m2 (CF 2000).
Rotary pump
For precise production and minimal waste
The most precise pumps on the market are used in this freezer, ensuring an accurate flow of product and guaranteeing production stability with repeatable results and low waste. The pumps are cleaned automatically during the freezer’s own CIP cycle.
IE3 and IE4 motors
High energy efficiency
Built with the most energy efficient motors, this unit keeps power consumption down to a minimum, thereby reducing running costs.
Patented cylinder design
High energy efficiency
This unit features a unique cylinder that enables a 10% increase in the heat transfer rate compared to older models of freezers. The outer diameter of the pipe remains identical, but the surface of the coolant channel is ribbed to maximize heat transfer.
Hygienic shaft seal
3000 hours component lifetime
This shaft seal is made of hard metal steel in order to withstand production of mixtures with coarse particles without wearing out the components prematurely. It has a recommended replacement time is 3000 hours. To further enhance hygiene, the spring is placed outside the product zone, thereby preventing product from becoming trapped during production.
Operator control panel
Increases efficiency, safety and traceability
A user-friendly touch screen panel shows operators what is happening in the individual unit and can be connected to the production control system, Tetra PlantMaster™ for an overall line view. This enables full production monitoring capabilities and access to a historic log for tracing production.
Patented start-up procedure
Reduces waste during start-up
In traditional freezers, the first 2 to 3 batches of product are usually wasted due to inaccuracies in overrun. But with this model, the overrun is accurate from the start, leading to an upper limit of half a cylinder of product waste at start-up. This feature saves a significant amount of money on expensive ingredients.
Mass flow meter A2 series
Controlled and economical production
A mass flow meter ensures that precisely the desired amount of air enters the freezing cylinder and is incorporated into the mixture. More or less air can be incorporated to vary product texture as needed, with minimal production fluctuations and hence minimal waste. The meter can handle up to 140% overrun, enabling products with a high air content.
Options
Multiple outlet pumps
Feed several product lanes without extra costs
Multiple outlet pumps make it possible to feed up to four product lanes with a single freezer, or eight lanes with two freezers, and still get a precise, consistent volume of product distributed into each container. With one freezer to feed up to four lanes of production you also reduce investment, start-up waste, spare parts and maintenance costs.
Dasher tray
Increases operator safety and protects your capital equipment
Uniquely, Tetra Pak® offers a pull-out tray which makes it possible to safely remove the dasher. It keeps the operators hands at a safe distance from the dasher’s sharp blades and prevents contact with the cylinder surface.
Cooling valves
Enables reduction in energy consumption
With these cooling valves, there is no pressure drop across the valve. This enables a higher suction pressure and hence lower power needs.
Line integration
Minimizes operator interference and reduces running costs
A communication package that enables communication between the freezer and the downstream equipment. Shared recipe handling and production hold signals reduce the need for operator interference. Also, by sharing flow signals to downstream equipment like ingredients dosers, the use of ingredients can be optimized to the actual outlet flow from the freezer.
Tetra Pak® Low Temperature kit for Continuous Freezer
Save energy and improve ice cream texture
The Tetra Pak® Low temperature kit freezes the product by up to an additional -3°C. These extra degrees give a more energy-efficient production process, as the product spends shorter time in the hardening tunnel and less energy is required for churning. Colder ice cream also results in an enhanced product texture and mouthfeel.
