Demonstration of Stage III Peterson Press

It softens the cellulose fibers, It makes it into a somewhat gelatin consistency. If you have had a Tamale you will have a good idea of the texture that can be achieved. In Mexico tamales are still made the old way with the nixtamal process using slaked lime or sometimes wood ash, this softens and loosens the outer cellulose husk which is partially washed away with water.

[zibbix]

Adding wood ash to the slurry, will break down the cellulose to make a better slurry. The same process is used to make hominy corn. See nixtamalization in Wikipedia.

@zibbix Does the wood ash soften/separate the cellulose fibers or break/dissolve them? The former is good, the latter is bad. We need the cellulose fibers to bind the briquette together when the raw material is compressed. PaulAlley@Comcast.net

I have a couple suggestions/ questions, for the spacers, in 3rd world countries would not tin/sheet metal spacers ( made from tin cans )be easier to find than acrylic. also more forgiving is dropped or used extensively second in stead of using an ejector pipe. make a shorter ejector that also uses the plunger.saving @ 8inches of pipe

Where can I buy one? I live in Canada.

[BeavertonRotary]

@qsdfcvgyjmkl The Beaverton Rotary Foundation sells complete press kits for $75 USD including ground transportation via UPS or FedEx. If you would like one I can send you a PayPal invoice.

Hi do you sell the micro compound briquette press thanks

[MrErnz23]

can u pls send me ur procedure tnx

[BeavertonRotary]

@MrErnz23 I need an email address to be able to send you a pdf file.  Would you like the English or French version? PaulAlley@Comcast.net

What's are the ingredients and proportions in your briquette?

[BeavertonRotary]

@wjj4832 The ingredients vary by what free waste material is available. Typical 3rd world semi urban areas often use something like shredded paper 50-60% (a few as much as 100%), sawdust 30-40% and 0-20% charcoal fines (the unsalable fine powder that is found in piles where charcoal is sold.) Rural areas will reduce the shredded paper content and replace it with rice husks, coffee husks, banana leaves or other agricultural waste.

Changing orientation so that the water doesn't soak the jack could prevent rust.

[MrLeonard55]

Hi. I really enjoy your videos. Can you give us some lengths of the pipes, etc?

[BeavertonRotary]

@MrLeonard55 The Beaverton Rotary Foundation sells plans for making a Peterson Press and directions for making fuel briquettes for $10. This can be paid online via PayPal or a check mailed to the foundation.

[lovegunz1]

do they drink the water after it comes out to or is it re used

[BeavertonRotary]

@lovegunz1 The water is reused to make more briquettes.

[oneshotveth]

Any reason why they couldn't be made into 12 - 18 inch logs (instead of the pucks that you are making in the video) to burn in my woodburning stove?

And maybe make a video explaining how you determine the lengths of the PVC pipes/ wood for the press...

[mladenkorotaj]

cool job

[jacksellers]

Your unit could also be used as a multi purpose unit. It could be also used to make oils from nuts and seeds for cooking.

[BeavertonRotary]

Could be used for any small pressing type application where you need no more than one ton of pressure. Would not be good for shelling or grinding.

[jacksellers]

I am impressed with the water saving device. This could be made portable (back pack) and people could walk out to make these fuel bricks without bringing excess wast to village. They could be made while in the farming field or while getting water.

[BeavertonRotary]

The small light weight press is ideal for carrying to villages where there are no roads.  Wet briquettes are fragile so you don't want to transport them until they dry (3-5 days). Making them in the field or at a distant water source is probably not a good idea.

V Good video.
