How to Make a Cold Smoke Generator - Pump

Introduction : Cold Smoke Generator - Pump

This is a follow on from the initial instruction on creating a vent and door for the smoke generator.

I have decided to break the instructions into a number of key parts which might just be useful components on their own.

Step 1: Parts

The aim is to use a few consistent parts:

  • 1 x Copper solder ring equal Tee 22mm;
  • 1 x Copper solder ring reducer 15mm to 22mm;
  • 1 x Copper solder ring straight coupling 22mm;
  • 1 x 50mm x copper pipe 22mm;
  • 1 x aquarium pump;
  • 500mm x upc pipe 7mm;
  • 50mm x Copper pipe 5mm;
  • 1 x Copper tank coupler 22mm;
  • 1 x wine cork; and
  • 1m x flexible pipe 25mm.

**A gas canister or anything else that needs a door**

**A smoking chamber where the food will be smoked in**

**The upc pipe can be longer or shorter, depending where the smoke chamber needs to be**

Step 2: Tools

Think this is the minimum you will need:

  • 1 x drill (potentially electric);
  • 1 x 30mm diameter hole saw (needs to be robust as cutting steel);
  • 1 x Solder;
  • 1 x Solder Torch; and
  • 1 x 7mm drill bit.

Step 3: Drill Pipe Hole

Using the hole saw drill the pipe hole in the canister:

  • Fit the tank coupler to the canister.

Using the hole saw drill the pipe hole in the smoke chamber:

  • Fit the tank coupler to the smoke chamber.

Step 4: Assemble Pipe

Assemble the pipework:

  • Solder the reducer to the equal tee;
  • Solder the 50mm pipe to one leg of the tee;
  • Create a right angle bend in the 5mm pipe;
  • Pass the 5mm pipe up through the reducer and pointing away from the pipe;
  • Reduce the diameter of the cork to fit the 15mm reducer;
  • Drill a 5mm hole down the centre of the cork;
  • Pass the cork over the 5mm pipe;
  • Attach the upvc pipe to the 5mm coper pipe; and
  • Attach the aquarium pump to the upvc pipe.

Step 5: Smoke Chamber

Connect the pipework:

  • Join the 25mm pipe to the two copper connectors.
