​​​​​​​​​​​​​​​​​​​​​​​Tetra Pak® Extrusion Tunnel M3

Tray tunnel system for ice cream production

The Tetra Pak® Extrusion Tunnel M3 is a tray tunnel system for the extrusion, shaping, filling, decorating and hardening of ice cream products including ball-top cones, desserts, wafer cups, sandwiches, cakes and logs, slices, bite sizes, stick products and candy bars. ​​

Quickfacts

CAPACITY

Up to 24,000 products/hour

APPLICATIONS

Ice cream sticks, sandwiches, cones, wafer cups, candy bars, slices, bite size, cakes, and logs

Features

Modular design

Modular design

Easily adapted to meet a range of production needs

The unit is designed in modules to maximize versatility with regard to the product. The layout of the equipment and its placement on the worktable can all be varied to enable the production of several kinds of ice creams

Servo cutter

Precisely repeatable production

The servo cutter slices the extruded ice cream with a high degree of precision every time independed of speed on line (standard deviation below 1%). This, combined with the fact that the Tetra Pak® freezer upstream delivers a well mixed and consistent stream of product, means that every single ice cream coming off the line is the correct and the same size

Start-up process design

Start-up process design

Enhances hygiene and minimizes product losses

Preparation for production is carried out outside the tray to ensure safe and clean start-up without the risk of contamination. As the ice cream mixture enters the extrusion nozzles, they are gradually cooled down. When they reach the right temperature and fill out the nozzle to form the correct product shape, the operator can move the nozzles over the product trays and set the cutter in motion.

Worktable-equipment interface

Worktable-equipment interface

Easy switch between different product types

This unit has a well-defined and standardized interface between the equipment and the worktable. It consists of identical mounting points where the equipment used to create (and differentiate) products is mounted. Production is easily varied, simply by switching and moving fillers, decoration equipment, biscuit dispensers etc.
Lubrication-free tunnel

Lubrication-free tunnel

Hygienic production

To prevent the risk of black spots, no lubrication is used inside the tunnel. Only lubrication free components are used on the inside, while the main drive is placed outside the freezing zone - which also facilitates maintenance.

Options

Dehumidifier

Dehumidifier

Extended run time between defrosting

If planning to run continuous operation for several days in a row, it is important to control the humidity in the hardening tunnel to prevent frost build up. The dehumidifier supplies dry air to the tunnel and keeps the moisture level down.

Automatic stick inserter

Automatic stick inserter

Enhances food safety and production reliability

With an automatic stick inserter, operators just need to load up boxes of sticks, and they receive an alert when it’s time to reload. This gives several advantages: there is no contamination risk from human contact; boxes cost less than bundled sticks, and one person can easily handle a four lane production line. This feature also supports the unit’s high operational speed – up to 200 sticks per minute per lane.

Combination trays

Combination trays

Broadening the range of possible products

Combination trays makes it possible to run different product types on the line without changing the trays on the worktable. The specially designed trays can be made to run up to 5 products on the same trays at varying capacities.

After cooler conveyor for stickles products

Optimizing footprint and energy consumption

When producing ice cream bars and bite size pieces on an extrusion line, chocolate needs to dry and harden after chocolate enrobing. While this is often achieved by having an additional tunnel connected to the line, with the Tetra Pak® Extrusion Tunnel M3, it’s possible to run an after-cooler conveyor through the tunnel house.

Add-on and exchange modules

Add-on and exchange modules

Enabling production of a broad range of ice creams

Whatever kind of ice cream you want to produce, there is an add-on module or modules to make it possible. Different stick product size and shape, full and half sandwiches, ice cream slices, candy bars, bite size, ball top cones, wafer cups, decorated cakes, logs etc.
