220V to 380V Converter for 34kW Coffee Roaster

Hello everyone,
I'm looking for a power solution for our coffee roasters that run on 380V 3 phase, using only a 220V 200A 1 phase circuit. The roaster's max power draw is 34.3 kW (only during preheat for 10 minutes), and I think it might be possible to run it from a single circuit with nothing else on it.
If needed, I'm okay combining transformers and VFDs into a single solution, but ideally we'd like one box that does it all!
Any advice is appreciated.

If yes, we can provide a single-box solution, but one question — what’s the max power of the roaster’s internal motors individually? Do they have a starting controller, like a VFD or soft starter, to limit inrush current at startup?

The 34.3 kW is the absolute peak during preheating. Most of the time, it runs under 30 kW. The hot air blower is 495W and runs with a VFD.

Most of the load comes from heating elements and halogen lamps:
Hot Air Ceramic Heater: 16 kW
Halogen Lamp: 16 kW
Drum Heater: 10 kW
Cooling Motor: 1.5 kW
Agitation Motor: 0.2 kW

Cooling and agitation motors are regular motors without speed control. The key point is — as long as we have 380V, stable at 60Hz, it works fine. I’m wondering whether a large VFD or a rotary phase converter would be better.

According to our calculations, your machine needs a peak current of 240A at the input end to run, so your power supply at the input end must reach 53kW.
