Cold Smoker

  1. I am building a coldsmoker (with hot plate) and my question is, Do I need air vent(s) and if so, where should be the placement?

    Yes you will need air vents it you will end up with stale smoke. You will need a lower vent and an upper vent to get a cross draft going. Size will depend on the size of your box.

    For most cold smoking, you do not need heat....

    Cold Smoking

    Cold smoking at 52-71° F (12-22° C), from 1-14 days, applying thin smoke with occasional breaks in between, is one of the oldest preservation methods. We cannot produce cold smoke if the outside temperature is 90° F (32° C), unless we can cool it down, which is what some industrial smokers do. Cold smoking is a drying process whose purpose is to remove moisture thus preserving a product.

    You will find that different sources provide different temperatures for cold smoking. In European countries where most of the cold smoking is done, the upper temperature is accepted as 86° F (30° C). The majority of Russian, Polish and German meat technology books call for 71° F (22° C), some books ask for 77° F (25° C). Fish starts to cook at 85° F (29.4° C) and if you want to make delicious cold smoked salmon that is smoked for a long time, obviously you can not exceed 86° F (30° C). Cold smoking assures us of total smoke penetration inside of the meat. The loss of moisture also is uniform in all areas and the total weight loss falls within 5-20% depending largely on the smoking time. Cold smoking is not a continuous process, it is stopped (no smoke) a few times to allow fresh air into the smoker.

  4. Thanks Guys

    I made my smoker out of a upright freezer. I have 2x 1" dia holes on the bottom on each side and a 3" chimney, 4' horizontal and 28" verticle. I cold smoked by putting 3 hot bricks on my pan of chips. I think the bacon turned out pretty good.

    I'll attach some pics
