TB20-W Water Cooled Temperer

The TB20-W is a water-cooled chocolate tempering machine offering a cost-efficient alternative to compressor-cooled systems, while still delivering controlled batch tempering.

The machine melts and tempers 20 kg batches of chocolate while giving the operator full control over all three tempering stages. The desired temperatures for melting, cooling and tempered chocolate can be defined and stored, and the three temperature levels in the tempering process are not limited by pre-set values or fixed temperature differences.

During tempering, 30–40 litres of water are used to regulate the cooling process. A 20 kg batch can be tempered in approximately 25–30 minutes, depending on chocolate type and starting conditions. Throughout the process, the total volume of chocolate in the tank reaches a uniform temperature at each stage before the next begins, ensuring consistent batch results.

The TB20-W can be used for both melting and tempering from start to finish, or solely for tempering pre-melted chocolate. When filled with melted chocolate at a minimum of 45°C, 20 kg of tempered chocolate will be available in approximately 30 minutes.

Highlights:

  • Water-cooled tempering system
  • Uses 30–40 litres of water to regulate the cooling process
  • Full control of all three tempering stages (melting, cooling and working temperature)
  • Individually defined and storable temperature settings
  • Uniform temperature throughout the entire 20 kg batch
  • Can be used for both melting and tempering, or tempering only
  • Stainless steel construction for hygienic and easy cleaning

How it works: Water-cooled chocolate tempering in 20 kg batches

The TB20-W manages tempering through three controlled stages: melting, cooling and final working temperature.

Cooling is regulated by circulating 30–40 litres of water during the tempering process. At each stage, the full 20 kg batch reaches a uniform temperature before the next stage begins.

In TB20-W it takes 30 minutes for a perfect tempering of 20 kg chocolate

Frequently asked questions about the TB20-W

How does a water-cooled chocolate tempering machine work?

A water-cooled tempering machine regulates the cooling stage by circulating cold water during the tempering process. In the TB20-W, 30–40 litres of water are used to control the cooling phase while managing melting, cooling and final working temperature.

How long does it take to temper 20 kg of chocolate in the TB20-W?

A 20 kg batch can be tempered in approximately 25–30 minutes, depending on chocolate type and starting conditions.

Can the TB20-W be used for both melting and tempering?

Yes. The TB20-W can manage the complete tempering cycle from melting to working temperature. It can also be used for tempering pre-melted chocolate.

What is the difference between water-cooled and compressor-cooled tempering machines?

Water-cooled machines use circulating water to regulate the cooling stage, while compressor-cooled machines rely on an integrated cooling system. The choice depends on production setup and available infrastructure.

Is the TB20-W suitable for batch chocolate production?

The TB20-W is designed for controlled 20 kg batch tempering where stable and consistent temperature management is required.

Product details

TB20-W is based on the experiences from previous models within the 6T range of similar kind of melting and tempering machines . The outside stainless steel surface makes it very easy for the operator to keep the entire tempering machine in a clean and nice condition. The agitator can be lifted up from the tank without using of any kind of tools.

The tempering machine is controlled by a special controller, which offer the following features:

  • The temperatures in the tempering process are set by the operator, and each temperature is independent from other temperatures. The operator can bring temperatures close to the limits of the standard recommendation – and further if required.
  • The temperatures can be stored. This ensures the same tempering result tank after tank – day after day.

The machine has a smooth stainless steel surface for easy cleaning.

Water supply and drain

On the back of the machine hoses for water supply and drain must be attached to the fittings. In the inlet fitting is a water reducing insert which reduces the inlet flow of water to 2,0-2,5 liter/minutes depending on the actual water pressure.

An example of a water-cooled tempering process in TB20-W

  • Chocolate melting temperature: 45,0 0C
  • Chocolate cooling temperature: 27,5 0C
  • Finished chocolate temperature: 32, 0C
  • Total tempering time: 26 minutes
  • Total cooling time: 14 minutes
  • Water used for tempering: 2,0 l / min
  • Water temperature: 10 0C in average

Conclusion: 20 kg of chocolate has passed the three tempering stages in 26 minutes. Cooling time by means of water was 14 minutes. App. 2,0 liter of water per minutes, at a temperature of app. 10 0C was used.
