Batch and continuous systems achieve the same result – chocolate that’s glossy, firm, and stable – but they’re built for very different operations. A batch machine gives artisans full control over smaller runs, while a continuous system is built for seamless, high-volume output.
At Artisan Industrial, we help producers at all scales find machinery that matches their production needs and future growth. Here’s everything you need to know about choosing the right chocolate tempering machine for your business.
Why you need to temper your chocolate
Tempering is the process of heating, cooling, and reheating chocolate to control the crystal structure of the cocoa butter. When done properly, it produces that signature sheen, satisfying ‘snap’, and long shelf life you expect from high-quality chocolate.
Simon, the Managing Director of Artisan Industrial, says: ‘When you buy a bar of chocolate and break it and it cracks, it’s shiny and glossy, and you can hold it without it melting straight away … all of that is a result of tempering.’
What happens if you don’t temper your chocolate?
Dull, streaky chocolate that melts too easily, sets unevenly, and can develop a white, powdery film known as fat bloom (which occurs when cocoa butter melts, separates, and resolidifies on the surface). The product will be inconsistent and have a less appealing texture.
‘It’s not necessary to temper when the chocolate is being served melted,’ says Simon, ‘or when it’s going onto a frozen product – like ice cream or frozen berries – because the quick temperature change as the chocolate goes onto the cold product makes tempering irrelevant.’

Batch vs continuous chocolate tempering machines: which do I choose?
Choosing between batch and continuous tempering comes down to scale. Batch machines suit artisan producers all the way up to semi-industrial outfits. Continuous systems are more suitable for large-scale or industrial production lines requiring a steady, uninterrupted chocolate flow.
Simon says the decision is usually straightforward for small-to-medium business owners: ‘You’re not just going to wake up one day and buy a continuous tempering machine. It means you’ve got the volume. It’s a whole other beast.’
Batch tempering machines (artisan to semi-industrial)
Batch tempering machines are the workhorses of smaller operations, providing flexibility and control. They’re ideal for small businesses, bean-to-bar makers, and boutique chocolatiers, producing anywhere from 10 to 100 kg per batch.
Artisan Industrial’s preferred batch systems come from Gami, one of Italy’s most respected chocolate equipment manufacturers. Their machines are known for their reliability, technical precision, and hygienic stainless-steel construction.

Key benefits of Gami batch tempering machines:
- Bain-marie heating system: Uses a double-jacketed water circuit for even heat distribution, protecting cocoa butter from burning and preserving the chocolate’s taste, aroma, feel, and look.
- Removable stainless-steel auger: Allows quick cleaning and easy switching between chocolate types. Ideal for small producers working with dark, milk, and white chocolate in the same facility.
- Accurate temperature probe near the outlet: Ensures the chocolate leaves the machine at a precise, stable temperature.
- Automatic overnight timer: Lets operators set the melt cycle the night before, so chocolate is ready for tempering in the morning.
- Built to last: Machines are designed to operate up to eight hours a day, five to seven days a week, supporting growth from artisan to semi-industrial production.
Continuous tempering machines (semi-industrial to industrial)
Continuous tempering machines maintain an uninterrupted chocolate flow through heating and cooling cycles, ensuring perfectly tempered chocolate hour after hour. They’re the backbone of automated lines where downtime equals lost output.
Artisan Industrial offers Tecnochoc’s continuous tempering range, including the T1 model, which bridges the gap between batch and fully industrial systems. While full-scale continuous tempering lines can handle up to 1,200 kg per hour, the T1 produces a steady 70-150 kg per hour, making it ideal for small-to-medium producers scaling up from batch systems.
Key benefits of the Tecnochoc T1 continuous tempering machine:
- Three-zone temperature control:
- A bowl with a jacketed water circuit that melts the chocolate and serves as a decrystallisation unit.
- A cooling cylinder with a gas compressor circuit that forms the chocolate crystals.
- A final heating cylinder that stabilises the crystals for perfect temper.
- A bowl with a jacketed water circuit that melts the chocolate and serves as a decrystallisation unit.
- Continuous flow via pump system: Ensures a constant supply of tempered chocolate for molding, enrobing, or depositing without manual intervention.
- Integrated mould dosing head: Unlike other continuous tempering machines, it comes with a built-in dosing head for quick, precise mould filling without extra equipment.
- PLC touchscreen control: Automatically monitors and adjusts temperatures and flow rates for consistent, repeatable results.
- Modular integration: Can connect directly to other equipment, such as cooling tunnels, enrobers, or depositors.
Key differences: batch vs continuous
| Feature | Batch tempering | Continuous tempering (T1 & beyond) |
| Production scale | Artisan to semi-industrial | Semi-industrial to industrial |
| Output | 10-100 kg per batch | 70-150 kg/hr (T1) to 1,200 kg/hr |
| Operation | Manual or semi-automatic | Fully automated with PLC control |
| Flexibility | Great for varied recipes and small runs | Designed for consistent high-volume output |
| Setup & cost | Lower investment | Much higher investment; scalable integration |
| Learning curve | Simple, accessible | Requires trained operators |
| Best for | Bean-to-bar, artisan chocolatiers | Continuous molding, enrobing, or depositing |
How to know when it’s time to upgrade
Recognising when to move from a batch to a continuous chocolate tempering machine comes down to consistency and capacity.
You may be ready to upgrade if:
- Product flow is limited by manual and batch tempering cycles.
- You’re adding automated molding or enrobing lines.
- Maintaining consistency across shifts has become a challenge.
FAQs
How does a chocolate tempering machine work?
A chocolate tempering machine works by carefully heating, cooling, and reheating chocolate to stabilise the cocoa butter crystals. This controlled process gives chocolate its glossy finish, smooth texture, and firm snap.
What’s the main difference between batch and continuous tempering machines?
Batch machines process chocolate in individual cycles, while continuous machines maintain an uninterrupted flow for larger-scale production.
Do I need a continuous tempering machine for artisan chocolate production?
Not usually. Continuous systems are designed for industrial lines. Most artisan chocolatiers use batch machines for their control and flexibility.
Can I switch between dark, milk, and white chocolate in the same tempering machine?
It depends on the machine. Gami batch tempering machines include removable augers, allowing quick cleaning and colour changes between chocolate types.
What size is right for my business?
If you’re producing under 100 kg of chocolate per day, start with a batch machine. Continuous systems are generally more suitable for industrial production.
We’ll help you find the right fit
You don’t have to come to Artisan Industrial knowing the machine you need. We can help you figure it out. ‘If you’re brand new, your first pain point will be price,’ says Simon. ‘We’ll usually give three options with prices and volumes. If you’re established, we’ll ask your volume, how many bars per day, and do the calculations from there.’
Artisan Industrial has decades of experience supplying Europe’s finest chocolate equipment to producers across Australia and Oceania. Whether you’re launching your first bean-to-bar line or scaling up to continuous production, we can help you find a system that matches your workflow and growth plans.
