TB20-1 Compressor Cooled Temperer

The TB20-1 is a small chocolate tempering machine designed to melt and temper 20 kg batches of chocolate while giving the operator full control over all three tempering stages.

All three temperature stages can be individually defined and stored, allowing the operator to fine-tune the tempering curve for different chocolate types. During tempering, the entire volume of chocolate in the tank reaches a uniform temperature at each stage before the next begins, ensuring controlled and consistent batch treatment.

The TB20-1 can be used for both melting and tempering from start to finish, or solely for tempering pre-melted chocolate. Its integrated compressor cooling system provides independent temperature regulation without the need for external water cooling.

For increased capacity and dual batch flexibility, see the TB20-2 compressor-cooled tempering machine. If you require a water-cooled solution with similar batch capacity, the TB20-W tempering machine offers an alternative cooling principle.

Highlights

  • 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
  • Integrated compressor cooling – no external water connection required
  • Can be used for both melting and tempering, or tempering only
  • PLC-controlled interface for process management
  • Stainless steel construction for hygienic and easy cleaning

How it works: The three-stage tempering process

The TB20-1 controls the tempering process by guiding the chocolate through three defined temperature stages: melting, cooling and final working temperature.

First, the chocolate is heated to fully dissolve all existing crystal structures. The machine then lowers the temperature in a controlled cooling phase to initiate the formation of stable crystals. Finally, the chocolate is gently reheated to the desired working temperature, ensuring proper viscosity and flow for further processing.

Each stage is independently adjustable through the PLC interface, allowing the operator to define the exact tempering curve for different chocolate types and production requirements.

Frequently asked questions about the TB20-1


How does a compressor-cooled tempering machine work?
A compressor-cooled tempering machine manages melting, cooling and final working temperature through controlled temperature stages. The integrated compressor regulates cooling without requiring an external water connection.

Can the TB20-1 be used for both melting and tempering?
Yes. The TB20-1 can manage the complete tempering cycle from melting to working temperature. It can also be used for tempering pre-melted chocolate.

Is the TB20-1 suitable for small chocolate production?
The TB20-1 is designed for small to medium-sized production environments requiring controlled batch tempering and consistent results.

What are the advantages of a compressor-cooled tempering machine?
Compressor-cooled machines provide controlled temperature management without external water cooling. They are well suited for batch production requiring flexibility and consistent quality.


How do I choose between compressor-cooled and water-cooled tempering machines?
Compressor-cooled tempering machines are typically suited for small to medium-sized producers who require high control and consistent batch quality. Water-cooled tempering machines are designed for larger production capacities and integration into bigger production lines.

Product details

TB20-1 is based on the experiences from previous models within the 6T range of similar kind of melting and tempering machines – and then supported by new technology. 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 tempering machine is controlled by a PLC, and this technology offer you the following features:

  • The entire machine is controlled from the touch panel, which has a graphics that intuitively guides the operator through the options available.
  • 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.
  • In total 3 combinations of tempering temperatures can be stored. This ensures the same tempering result tank after tank – day after day.
  • The machine can be programmed to start tempering at a pre-defined time. It means that well tempered chocolate can be available at any time: In the morning when the staff turns in – after lunch hour – or at any other pre defined time.
  • The temperature progress during the tempering process can be visualized for later inspection.
  • The machine has a smooth stainless steel surface for easy cleaning, and the agitator can be lifted up from the tank without using of any kind of tools.
