Cold smoking in warm climate

^{Image from Smokai's page about fridge conversion}

Living where it’s usually too warm to cold smoke in ambient temperatures,  I’ve been thinking about making a cold smoker by mounting a smoke generator to a working refrigerator.

The idea is that the fridge will be on and kept at the desired temperature using an Inkbird controller.

Will this work and is it food safe ?
