Tom Sampson recently posted that his effort to develop a device to keep cocoa butter warm while spraying or airbrushing it has progressed. Here is his update:
QuoteSome months ago I posted my idea for a heater for an airbrush. I wasn't happy that it ran off batteries so this prototype is mains powered. In this test the liquid in the airbrush has maintained a temperature of 31C for 12 hours. I am hoping to add 2 accessories one which will heat 500ml of liquid and another which can be used with a larger airbrush.

Setting the cup temperature at 31C also heats the rest of the airbrush if is made of conducting metal and most are stainless steel. For larger cups made of polyurethane then I am working on a 3 x 0.5cm cylinder which sits in the medium.
I asked him about the possibility of developing a version for the Fuji or similar spray guns, and he immediately responded by asking me to provide the dimensions of the Fuji cup. The fact that the Fuji is pressurized and has a mandatory screw-on cap seemed problematic to me, but he stated that his device fits on the outside of the cup. I think that most chocolatiers with a Fuji use the small metal 75cc cup, but, as stated in the second quote, Tom is also working on a version of his device for polyurethane cups (which is what I believe Kalle Jungstedt uses in his production facility).
