[Stoves] {briquetting} Fwd: new briquette press from Hungary

[Sanukaji Shrestha]

Dear Richard and Nora,
Thanks you very much for sharing car jack briquette press for multiple
productions. What a co-incidence? I was talking with a group of people from
rural village today about their cooking practices which requires mostly
sticks (fire wood). They were asking me to design cheaper model of stick
press to use briquette stick in mud stoves in the village. I showed them
some sample briquettes of 12"x2" and 18"x4" sticks produced in screw press,
but that was very expensive (say about US$150 to US$200). We want cheaper
design so that our villagers can afford easily.
>From 2004 to 2006, we disseminated Legacy's lever press with hard wood. In
2007, we introduced screw press with handle. Both were press-down models.
In 2011, we introduced push up model with 2 tons' car jacks designed by Bob
for producing different sized briquettes in one press such as 2", 3", 4"
and 6". Four sized briquettes can be produced in one press in different
time. So far we distributed five car jack press in different communities.
Although we trained the community housewives on multiple use of car jack
press, majority of people like to have screw press for easy operation.
We also produced a screw press for multiple productions. It has five
3"-cylinders which is capable to produce 30 pcs in five minutes, but 25 is
comfortable. This press was sold to ICIMOD for its exhibition in Godavari.
We also designed a handy press with a piece of fiber sheet with 150 holes
supported with dividers and two pieces of pipes. We can use CD as dividers.
It is a low-density briquette press which costs about US$6.
So far we sent one screw press in Haiti, 10 presses in Colorado University,
2 in Afghanistan, 2 in India, 2 in China, 2 in Pakistan, one in Australia.
Since we are trying to give multiple choice to the communities, it would be
very helpful if you share your design to us for testing in Nepal.
I look forward to hear from you,
Warm regards, Sanu Kaji
