sagekai:Hi, and thanks in advance for any wisdom you can share! I'm currently using a Chocovision Revolation 3Z and I'm looking to get a chocolate melter to melt enough chocolate for an additional batch overnight so I can be more productive... Unfortunately the Chocovision and Mol d'Art melters aren't NSF certified, which I need it to be so I can use it in a commercial kitchen. And the Savage Bros smallest unit is well out of my price range at over $4500. Does anyone know of an NSF approved chocolate melter for under $1500 that can handle 30-45 lbs of chocolate? Thanks so much!
Try an NSF-certified buffet warmer that does not require water. Use NSF-certified hotel pans to hold the chocolate. The buffet warmer should holds 8" deep hotel pans but only put 4" or 6" deep pans in it as you do NOT want the pans to touch the bottom as the temperature controllers tend to be not very sophisticated and if the bottom of the pan is touching the inside bottom of the warmer it can scorch the chocolate. Rather than using full-size pans, use third-size pans to make transferring chocolate easy. (You can also put in a new pan of chocolate when you take out a melted one during the day.) Make sure to cover the pans with lids overnight. You could also put an upside-down sheet pan over the top overnight to make it more efficient.
Total cost, under $250 depending on the buffet warmer you get. Much less, if you already have the hotel pans and lids.
If you want to make sure that you don't scorch the chocolate and get it to melt faster -- get a temperature controller and affix the sensor to the inside bottom of the warmer. Set the temp for ~140F (~60C). You can now set the temperature controller on the front of the buffet warmer to a much higher temperature knowing that the temperature controller will keep it from getting hot enough to scorch the chocolate - the external controller will cut the power if it gets too hot. When it cools down the power will come back on. After a little tweaking you can find the front panel setting that gives you the most efficient cycle.
Controllers that will do this are under $100.
