The Fabrication Process
Stationery Solar Powered Fish Dryer
The following step by step process is recommended for the
construction of the stationery solar powered fish dryer:
• Selection of the site – Avoid marshy, muddy lands.
Sandy soil is best. The area needs to be levelled and
have a proper drainage system. The area should have
direct sunlight (unhindered by trees etc.) The dryer
needs to be expos ed to sunlight from 9.30a.m to 3.30
p.m to work efficiently.
• Select suitable workers - Call for offers from
prospective artisans for fabrication of drier as per
detailed working drawings. The skills of the artisans
and the construction workers need to be assessed in
the selection process.
• Clear and prepare site area - An area of at least twice
the length and breadth of the dryer’s structure should
be cleared of scrub jungle.
• Excavate ditches to lay foundation - The soil should be
excavated as per B.O.Q submitted for civil works.
• Erect the foundation walls, and timber columns in place
as per B.O.Q.
• Prepare floor – Fill and ram the earth, adding water as
required to compact the earth firmly and level the area.
• Construct half walls and fix chimneys- The chimneys
need to be incorporated into theside walls and thus
should be constructed simultaneously. The chimneys
need to be fixed with inlet air ducts and roof ventilators.
Next the rodent guard needs to be put in place right
round the 2.5 ft half brick wal level. Plaster and
smoothen both sides of the brick walls. Apply matt
black paint on the exterior walls and outer side of the
chimneys.
• Construct timber super structure – this serves as the
framework for the upper walls and roof.
• Place the matt black coated metal collector plates on
the support framework, making adequate provision for
space between any two plates.
• Erect and fix framework
• Construct half walls and fix chimneys- The chimneys
need to be incorporated into the side walls and thus
should be contructed simulataneously. The chimneys
need to be fixed with, inlet air ducts and roof
ventilators. The in place. Next the rodent guard need to
be put inplace right round the 2.5 ft half brick wall level.
Plaster and smoothen both sides of the brick walls.
Apply matt black paint on the exterior walls and outer
side of the chimneys.
