Technical brief
• Construct timber super structure – this serves as the
framework for the upper walls and roof..
• Plac e the matt black coated metal collector plates on
the support framework, making adequate provision for
space between any two plates.
• Erect and fix framework
• Install G.I. wire support system for the roof
• 12. Apply double sided tape on the wooden framework
• 13. Stick on the “cut-to-size” polyethylene sheeting to
the superstructure of the drier, using double sided
adhesive tape so as to ensure it is air tight. As a
protective measure, fix wooden beading over wooden
framework using tintacks. Use G.I wires to support the
chimneys.
• 14. Cement render and smoothen floor allowing for a
gradient of 1 in 40 lengthwise and make provision for
drainage outlets.
• 15. Install bird and insect proof netting over the air
inlets. Provide hoods over these inlets to prevent rain
water beating in.
• 16. Fix entrance door
• 17. Fix plastic coated G.I mes h on the supports for the
drying platform.
Mobile 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 exposed to sunlight from 9.30 a.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 site -An area of at least twice the length and
breadth should be cleared of scrub jungle.
• Excavate for the foundation- The soil should be
excavated as per B.O.Q for civil works already
submitted.
• Prepare floor – Fill and ram the earth, adding water as
required to compact the earth firmly and level the area.
• Construct the half masonry wall
• Construct the cement rendered and paved floor.
Ensure a gradient of 1 in 40 towards either of the long
sides and provision of drain pipes
• Paint the external masonry walls and floor with matt
black
• Erect the arches and roof vent structure
• Provide G.I wire support system for the roof
• Apply of the double sided tape to the superstructure.
• Apply the ‘cut-to-size” polyethylene sheeting to the
superstructure of the drier, using double sided adhesive
tape already applied to the superstructure ensuring
perfect air tightness. As a protective measure apply
and fix wooden beading over superstructure using
coach screws
• Apply bird and insect proof netting over the air inlets.
Provide hoods over these inlets to prevent rain water
from beating in.
• Fix the entrance door
