Check out Rob’s ice cream machine… via Tim.

These are two photos of an ice cream machine made by a local Mennonite. It uses a small gas engine and pulleys to tun the crank for the ice cream. The engine also helps bring the temperature of the consumer grade anti-freeze to -67 F in the coils. The whole entity sits on a small pull wagon. The ice cream takes about 5-10 minutes to make. Cool stuff.

  1. Standard antifreeze uses ethylene glycol. Propylene glycol may be substituted and is non-toxic (in fact, it is approved as a food additive).

  2. Haha, I recognize the engine as a 6.5 horsepower Harbour Freight Special. They are on sale this month for just over $100. I just got mine this morning as a backup for a generator for Hurricane season. Plus you can mod it to run on 100% ethanol pretty easily. Would be interested to see some more specs on the cooling aspect of this setup…

    Cheers,

  3. I would like to see specs also. I make about a gallon of ice cream a week and am getting tired of the poor quality of the commercial machines like Rival.

  4. Hmmm, how do you get ethylene glycol down to -67F. It becomes solid at a much higher temperature. Are they using a two part system transferring from a different refrigerant to the ethylene glycol?
