Hello all,
I am hoping to set up a WVO collection and filtration operation up in Canada, where the weather isn't so hot (frequently -10C at night during the winter)
I've already got a deal with a local oriental restaurant to collect ~50 gallons a month from them. However obviously the cold weather complicates things. I will not be able to pump the WVO, and instead will have to simply take away the full barrel and replace it with an empty one.
It also complicates filtration. I was going to use 2 1000L totes, one for the unprocessed WVO, and after it goes through the misting, heat settling and filtration, another for the clean filtered VO. I was planning on pulling from the tote into a heated misting barrel and then heat it in-line through the filtration process. The problem is during winter I would need to keep the entire tote warm, which poses a significant cost. When I got barrels home I'd use a barrel heater to thaw them before transferring them to the 1st tote.
My other concern is that once I put filtered VO into barrels to store them, can I store them outside? If they freeze, thaw and refeeze continually, would it harm the VO?
Any thoughts? |

I had to collect wvo this way for several years. Much easier if you can get the restaurant to pour the wvo back into the cubees it comes in after it has cooled. Full cubees weigh around 35 pounds and can be lifted and even stacked fairly easily. They can be re-liquified (if frozen solid) easily by setting them on a water bed heater pad.
Drums are much harder to move by hand. I can post a few simple designs for inexpensive ways to move/load them without busting your back if this simpler option is no..well.. and option.

Maybe I am missing something...are you planning to process more than this 50 gal per month? If so ...and you have to use drums to collect and transport in...you can just mist wash in the drum after you have heated it to around 80-90F. You can then transfer your "washed" wvo to a settling tank/tote (up flow type) through a 10 micron filter and draw off the top surface using a floating pickup.
Passing this through a second filter (of whatever micron rating you want) you can then use it as fuel or place in a holding tank.
The amount you plan on processing per month effects what I would recommend as the optimal processing equipment for your operation. So if you can clarify that it would help.

Once wvo has had the particulates and suspended water removed you can allow it to freeze if you wish and simply liquefy the amount you need to remove when you need it. Freezing processed wvo won't harm it.
