Batch or continuous
Batch and wheel machines temper a tank at a time and suit hand work. Continuous machines temper a flow and feed an enrober or depositor. Output figures for the two are not comparable.

A tempering machine is judged on whether the chocolate leaving it is in temper every minute of the shift, and that depends on cooling you may have to supply yourself, which many quotes leave out.

01
Batch and wheel machines temper a tank at a time and suit hand work. Continuous machines temper a flow and feed an enrober or depositor. Output figures for the two are not comparable.
Continuous tempering removes heat in a cooling zone. Some machines have a built-in chiller; others need a steady chilled water supply from you. That is a second machine to buy and install.
Continuous machines heat, cool and reheat in separate zones. Ask how many zones, who makes the controllers, and whether each zone temperature is shown and logged.
Kilograms per hour is usually rated on a standard dark chocolate. Milk, white and high-viscosity recipes may run slower. Ask the rating for your type.
Unused tempered chocolate must return and be re-melted. Ask whether return piping and a melting tank are in the scope.
02
Chinese continuous tempering machines are often named QT plus a number. In the two QT250 listings checked the number matched the stated kilograms per hour. Treat it as the rating on a standard chocolate, not on yours.

| Require this | A pass looks like |
|---|---|
| Temper your own chocolate at the rated output for at least one hour, taking a temper test every quarter hour. | Every sample sets with gloss and snap within your normal setting time. |
| Log every zone temperature for the full run. | Each zone stays at its set point, log attached to the FAT record. |
| Stop flow for a short break and restart. | Chocolate back in temper without re-melting the circuit. |

A melting tank with temperature control. Compound coating does not need tempering.
A tabletop batch or wheel tempering machine. A continuous machine needs steady flow to stay in temper.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.

Every machine we source in this area is on the Food & candy page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
Temperature control precision, heat exchanger design and parts supply. Test temper stability over a full hour on your chocolate before you decide.
Model and serial against the declaration, zones counted, chiller present if quoted, guards at the pump and screw, and a temper test every quarter hour on your chocolate.
A Declaration of Conformity under the Machinery Directive 2006/42/EC until 19 January 2027, then the Machinery Regulation (EU) 2023/1230, plus 2014/35/EU and 2014/30/EU. A CE mark alone proves nothing.
The company placing it on the EU market, named on the machine or documents, which checks the conformity file. Buying direct, that is you.
