The document describes the design and components of a seed processing plant. The plant is designed based on the characteristics of the seed grain and impurities that need to be separated. The capacity of the plant depends on the capacity of the seed cleaner, which is the main machine. Other machines also work to separate materials based on differences in seed and impurity characteristics. These additional machines are matched to the cleaner's capacity for effective utilization. The plant building includes a receiving-cum-drying platform, processing area, and auxiliary building. Key processing machines include a scalper, air screen cleaner, specific gravity separator, indented cylinder, and elevator.

2. • Seed processing plant is designed, based on the
characteristics of seed grain and the impurities
present in it, which need to be separated.
• Capacity of plant is known by the capacity of the seed
cleaner which is the basic machine in the seed
processing plant.
• Other machines, which work on the principle of
separating the material, based on difference in
characteristics of good seed and impurities are
included in the plant.
• Capacity of such machines are kept matching with
that of cleaner to have effective utilization.

6. • In addition to building discussed above, a
provision will also be made for generator room.
• Sufficient length of road will be provided to
connect various functional buildings with each
other and main highway.
• Internal road will be 3.6 m wide. Boundary wall will
be provided all around the complex for security
reasons.
• One tube well is available at the site, which will be
used for construction works and drinking as well.

7. • The processing plant building will be
constructed as per CPWD/PWD norms.
• It will have tubular trusses, AC sheets pitched
hole roof, cement concrete flooring finished
with water-proofing cement paint, aerated,
ventilated, rat proof and bird protection.
• Sealed doors will be provided in these
buildings. Buildings will be suitably planned to
have interconnection for movement of seeds
and materials.
