How does a chocolate tempering machine work?

The world of chocolate sometimes seems like magic: smooth, shiny chocolate that breaks with a gentle snap. Behind this magic lies a precise process called tempering. Proper tempering gives chocolate the texture, shine, and stability we know. To achieve a perfect result every time, many use an advanced solution: a chocolate tempering machine.

What is Temperor and why is it important?

Tempering is a process of controlled heating and cooling of chocolate to stabilize the cocoa crystals. When tempered incorrectly, the chocolate takes on a grainy texture, dull color, and a whitish appearance on the surface. It may also break unevenly and melt quickly in the hand. In contrast, precise tempering produces shiny, stable, and pleasant-to-eat chocolate.

How does a chocolate tempering machine work?

A chocolate tempering machine performs the precise steps of heating, cooling, and maintaining a stable temperature for us, in an automatic and controlled manner. It heats the chocolate to the temperature required to break down the crystals in the cocoa, then gradually cools it to the ideal temperature to form stable crystals. The machine then maintains the correct temperature so that the chocolate remains ready to work for a long time. Furthermore, the machine provides constant movement to the chocolate during the process, which contributes to the even distribution of heat and ensures a consistent result every time. In other words, a tempering machine allows you to work comfortably without the need for endless checks with a thermometer.

The benefits of working with a professional tempering machine

Such a machine saves time and prevents mistakes. It allows for the rapid production of large quantities, without compromising quality, and ensures a uniform and fast result day after day, a significant advantage when working with customers and in repetitive production processes. Another advantage is the ability to keep the chocolate ready for use over time, without having to start the tempering again at each stage. This is especially useful in the production of pralines, chocolate sheets, cake decorations, and chocolates for filling molds.

Compatibility with different types of chocolate

Dark, milk, and white chocolate require different tempering temperatures, as each contains a different percentage of cocoa butter, sugar, and protein. Dark chocolate, for example, is typically heated to a higher temperature to break down existing crystals and develop an exceptionally smooth texture. In contrast, milk and white chocolate are more sensitive to heat, and therefore require a more precise and lower temperature range to prevent scorching or discoloration. A quality tempering machine allows for complete control: the heating, cooling, and working temperatures can be preset according to the type of chocolate used, and maintained over time. In addition, advanced machines are equipped with a smart system that saves recipes for each type of chocolate, so that each operation can be repeated to exactly the same process without the need for recalibration. The result is chocolate with a perfect shine, smoothness, with a gentle snap when breaking, and a consistent taste in every bite.

Who needs a tempering machine?

Confectioneries, large bakeries and praline manufacturers all benefit from the ability to maintain consistent quality and high professional standards. Cafés that make fresh desserts also use the machine to improve work efficiency and maintain the appearance of chocolate layers, coatings and decorations. The machine is suitable not only for industrial production, but also for small businesses offering handmade chocolate boxes or personalized products. In addition, pastry schools and professional baking schools incorporate Tempur machines to provide students with correct work habits and practical tools for work in the real world.

For those looking for bottom lines because the oven is beeping:
Baking with controlled air technology saves energy, affects the excellent taste, optimizes the work and can be controlled remotely. You are invited to get to know the MIWE IN ROLL oven.

So what is air control and what is it used for?
A short lesson on energy:

The amount of air circulating in the cycle and passing over the baked product has an immediate effect on the baking results .
The physical background for this reason is also easy to understand – above all it is known that two parameters are responsible for transferring the energy from the air to the product:
The air temperature (and for a more focused definition – the difference in temperature between the air temperature and the product temperature) and the amount (or speed) of the swirling air over the product.

The two parameters determine each other. At a warmer air temperature, the amount of air can be reduced by transferring the same amount of energy to the product. On the other hand, if more air is swirling – you can settle for a lower air temperature, and still transfer the same amount of energy to the product.

In fact, in the baking process it is quite clear that there are limitations. Of course, you cannot increase the amount of air as much as you want (and of course you cannot lower the baking temperature without limit), without disrupting the baking processes.

So after we learned about temperature…

What are the advantages of controlling the air flow in the oven?

Various advantages will be available to the baker if he can control the amount of air separately from the control of the baking temperature. The physical process described does work well in baking many products.

– Reducing the baking time while increasing the amount of air in the oven, which enables energy savings

Each baked product has its own parameters regarding heat conductivity and volume/weight ratios. That is, if we study the product features in depth, it seems that each product requires its own amount of air and temperature level.

There is an ideal combination of the amount of air and the temperature in each baking oven (due to the different climate conditions), in each baking process, in different seasons and at different points in the world. It is clear to every baker that a lower temperature (or gentler baking) is required as the product is rich in fats and proteins.

On the other hand, the actual improvement that can be achieved as a result of this ideal combination, instead of the conventional method of controlling the temperature alone, is most impressive in different types of pastry, such as yeast cakes, cakes in chuss or cakes in a mold, where the quality of the final product is affected in a positive and visible way when varying amounts of air.

Controlling the amount of air in the oven can also compensate for changes in the baking result caused seasonally due to weather changes, humidity and more. For example: the relative humidity is completely different in summer and winter. In the summer, crispness problems can arise due to low humidity. If we bake in the summer with a greater amount of air in the third and last stage of baking, we can stabilize the crispiness.

The Air control method

The amount of air is controlled by an electric valve (sliding door) located between the combustion chamber and the baking chamber. This valve, which can work for years without problems, regulates the air flow and thus determines the amount of air flowing in the oven.

This valve also closes automatically and without delay in two additional cases to save energy: during steam activation and when opening a door. When steam is injected into the oven, the heating system is completely sealed and separated from the baking chamber into which the large amount of steam is injected. Only after the effect of the steam does the valve return to its place according to the baking program. As a result, the steam does not pass through the combustion chamber, which prevents the cooling of the oven due to the steam at least by 10º – as was the case in the past in ovens with speed controllers and in all conventional ovens, in which it was necessary to start the baking process at a higher temperature.

According to Miwa engineers’ calculations, it is possible to save up to 10% in energy costs as a result of this method, and in addition – the lifespan of the combustion cells has been especially extended.

And in case of a malfunction in the valve, you can easily open it manually and continue baking. Also, since the steam must fill only the baking chamber and not the combustion chamber (as in conventional ovens), a higher amount of steam is created than the same amount of water, and of course in less time and less maintenance costs in the future.

And the other advantage of the method is the possibility to flow up to 1/3 more air into the oven when needed beyond the amount that could be flowed with the speed controllers.
