Don't try to recycle your bisquettes. After being used once, and dropped into the water bowl the bisquettes will most likely begin to fall apart in the chute, jam while feeding, and you will have to take the generator apart to clean it.
I'm a New Yorker, and I'm going through the same cold spell, and it will get colder this weekend. One thing you can do when it is this cold is to leave the generator hooked up to the cabinet. Unplug the power cord that connects the cabinet to the generator, so the heating element doesn't produce any heat. Leaving the top vent wide open, the amount of heat from the generator only may still take you over temperatures for cold smoking, but you can prop the door open with a pencil to allow heat to escape, but still monitor the cabinet temperatures. There will still be plenty of smoke inside the cabinet. Some members will place ice inside the cabinet to help keep the temperature down, but I don't feel it will be necessary during this cold period.
If you find that with the generator attached to the cabinet, and the temperature is below the temperature you want to cold smoke at, you may have to periodically use some heat from the heat element.
I forgot to mention when you use the cold smoke adapter in cold weather, the smoke does not flow that well. It is best not to fully extend the hose, and keep the generator close and below the level of the cabinet.
