"New chocolate innovations 2022 and beyond"
In a fast-paced global market, it’s difficult to keep up with today’s everchanging consumer tastes and demands and there are many local and global drivers that are influencing these changes. Brands that stay head lead by emulating credibility, being contemporary and innovative.
Types of chocolate
Before diving into the details of the chocolate production equipment, let’s first explore the types/colours of chocolate. There are three main types of chocolate: dark, milk, and white. Dark chocolate contains a higher percentage of cocoa solids, while milk chocolate has added milk powder or condensed milk. White chocolate mass is made with cocoa butter, milk, and sugar but does not contain any cocoa solids. Each type of chocolate requires a specific tempering process to achieve the desired texture and appearance.

How does the tempering process work?
To get informed about the different tempering machines that can be useful for your production line, we first explain the tempering process. The tempering process involves heating and cooling chocolate to specific temperatures to ensure the chocolate has the right crystal structure. When tempered chocolate is melted, the cocoa butter crystals separate and form into different structures, including unstable, beta, and alpha crystals. To achieve the desired texture and appearance, chocolate needs to be cooled and heated to specific temperatures to promote the formation of stable alpha crystals.
The tempering process involves three stages: heating, cooling, and reheating. The heating stage involves melting the untempered chocolate to a temperature between 40-50°C. The cooling stage involves cooling the tempered chocolate to a temperature between 26-28°C while stirring the chocolate continuously. This process promotes the formation of stable alpha crystals. The reheating stage involves heating the chocolate to a temperature between 30-32°C to remove any unstable crystalline structure and ensure the chocolate is smooth and glossy. Now we know more about the hot chocolate melter and tempering of chocolate, we move on to the different machines that are available on the market.
Which different tempering machines are on the market?
Tempering chocolate by hand can be a time-consuming and challenging task. As a result, tempering machines were invented to make the process more efficient and consistent. There are various types of tempering machines available on the market, including:
- Traditional chocolate tempering machine: This type of machine uses a column design and a heating and cooling system to temper chocolate. The chocolate is poured into the top of the machine and flows through the column, where it is heated and cooled to achieve the desired texture and appearance.
- Automatic chocolate tempering equipment: These machines are computer-controlled and use advanced technology to temper chocolate. They offer precise temperature control and can temper large amounts of chocolate quickly and efficiently.
- Batch chocolate tempering machine: This type of machine is ideal for small to medium-size chocolate production. It uses a bowl size up to 30-40 kgs of chocolate per hour to heat and cool chocolate.
- Continuous tempering machine: This type of machine is ideal for large-scale chocolate production. It uses a continuous table for chocolate blocks metering and can produce up to 2000 kgs of bulk chocolate per hour.
