Dear All,
I am following the group and I find it very interesting. Thank you to
all for your contributions.
I work in tea in China in a private initiative project aimed to increase
the sustainability of the organic tea garden and the local community.
Among other actions, some money is allocated every year to finance small
projects. I am looking into biochar stoves to improve efficiency use of
firewood of the local households (currently burning wood and coal),
however what I am more interested in at this moment is into the
possibilities of using pyrolysis to supply the energy needed for tea
processing while enjoying other benefits (i.e., biochar for the tea
garden soil, waste management by using alternative feedstock such as pig
sludge, producing vegetable coal,…).
I am not sure if this is the right place to raise the question … but I
go on:
I know there exists pyrolysis systems to generate heat but the scale is
too large for the needs in the tea factory. I have explored with some
companies and the minimum feeding rate of the module is 250 kg/hr of
biomass and our needs lay somewhere 300-600 kg/day of biomass (12-24
kg/hour). So my question is, do you know if pyrolysis modules to produce
heat (and biochar as side product) can be scaled down to what I need?
And, if yes, do you know of any company working on this?
Thank you very much! and sorry if my question was raised in the wrong place.
Warm regards,
Pablo
Brief description of the area: The tea factory is located in a remote
mountain area (see some pictures attached). In the factory the tea is
first heat up to stop enzyme activity, then is rolled and finally
roasted. Currently the first heat up and roasting is done using wood and
vegetable coal and the rolling uses electricity. To process the tea of
one year the factory uses 50 ton of wood trunks (big trunks, with some
water content), 5 ton of wood brunches (as fire starter, dry thinner
wood), 3.5 ton of vegetable coal and 35 MWh.
