Okay, I know I have said that I would post some pics for a long time now. I guess better late than never.
This is my personnal processor and may not work for everyone and should only be used as a guideline. If you are poor (or cheap) like me this is probably as low cost as you can get and still make fairly large batches of Bio. This processor is constantly evolving as I find more parts and free stuff I can use.
Junk yards are your friend.
Thrift stores are your friend.
Dumpster diving and trash picking is strongly encouraged.
Drums- 55 and/or 35 gal
Bed frames or other scrap metal
heat source ( old turkey cookers are great)
Big chunk of something heavy (I used a 4x4 post)
various little bits of plumbing (there's no hard rule on this just make sure they are galvanized)
Cut the top off the Drum and grind/file/beat the sharp edges off.
Use the big chunk of something heavy to beat the bottom of the drum until it is rounded out. Try to keep the beating in the center of the drum so it drains completely.
Make a frame for the drum to sit on. I used old bed frames you can usually get for free out of the trash.
Weld a pipe flange to the bottom of the drum that will accept 3/4 inch pipe on the small side. Make sure to grind off the galvanized finish before welding
. After it is welded, drill several holes in the bottom of the drum inside the footprint of the flange.
Here is a close up
Attach a pipe nipple to the flange followed by a valve and fittings that you choose to get the product out of the drum and into buckets. You can see the rounding of the bottom in this pic.
The final step is attaching the heat source. I used the guts out of a turkey fryer and mounted it accordingly. Your heat source is going to determine how you mount it.
That's it, You're done with the basic processor.
I use the below processor for small batches and to break any emulsion I might get
I have a total of about $15 invested in this processor but I can get drums for free. Add the price of a drum and you should be in the ballpark.
ON TO THE WASH DRUM!:Thumbup:
