Hi everyone. I currently can make about 10 liters of a hot process emulsion (specifically, hair conditioners) at a time by utilizing 3 hot plates and large beakers. I'm outgrowing this batch size and am curious about the type of equipment to make larger batches. What type of equipment does a bigger lab use to heat up each phase adequately and then combine them?

You can purchase kettles or small tanks if you have a place that has a boiler and heating system. I have seen companies use large cooking pots as tanks with hand held and detachable mixers. Heating is down on hot places or an electric heater. Tanks may come with and without mixers (centerpole and side sweep) .
If you are making thick products like the conditioner I would recommend something with a side sweep. Manual sweeping is a pain. I hope this helps.
a 200L drum, second hand will cost you $10, you get a drill and a paddle and you are in business I guess. To heat a you can get 2 or 3 heating units used for home brew... they can heat your mix to 40 plus degrees...
You can go to 50 L batches, but this is not lab scale anymore.
The owners are great to work with.
Their bottling tanks are what I use for my company and they come in a wide range of sizes. All water jacketed for even heating.
