(ton per day).
• Plant generally runs 12 hrs in a day due to
power cut.
Raw Material Used in Process:-
• Maze
• MBM (Mixed Bone Meal)
• Bran
• Khali
• Soya
Odor Issue
• MBM is the source of odor
• The Odor generates at stacking area
where MBM stack in Plastic Bags and
also the outlet of Cyclone.
Process Units
• Hammer Mill
• Mixing Mill
• Cooking section
• Pellet Section
• Cooling Section
Process Units
• All raw materials puts into the chamber
in which through conveyor it goes to
hammer mill.
Hammer Mill
• Hammer Mill crush all materials and
then transfer it to the mixing mill.
Mixing Mill
In Mixing Mill some medicines and enzymes are mixed with feed
for birds they are as follows:
1. Toxin Binder
2. Cozuril
3. Sodium Bicarbonate
4. Staquinol Plus
5. Phytase
6. Xylanase
7. Trace Mineral Mixture
8. Biocoline
9. Lysine
10.Methionine
11.Vitamins
12.Salt
13.Di Calcium Phosphate
Cooking Mill
• In cooking Mill feed cooks at 80 degree.
• After that it goes to pellet chamber.
Pellet Section
• Here Feed Converts into pellet form.
Cooling Section
• In Cooling Section feed cools from 80 to
60 degree.
Cooling Section
• It is a very important section odor
generates from this section.
• The main point is that it is not having any
compressor or blower for cooling.
• It is just like exhaust fan who lifts the hot
air of cooking section and send it to the
outer environment.
• There is a one fan in this cooling system
acts as a exhaust fan.
Air Section
• After pallet formation the fan lifts the air
from this section and send it to the
cyclone.
• Cyclone is used because Fan of cooling
system also lifts some product, and due to
this cyclone the product material again
comes into the mixer mill.
• So cyclone recovers the product and air
goes into the environment.

Air Section
• In fig 1 there is a cooling section one pipe of 16
inch attached to the upper part of that section
and a fan which is attached to this pipe is at third
floor of plant.
• Air and dust picked by this pipe line and send it
to the cyclone.
• In fig 2 cyclone attached with the fan who lifts air
and dust.
• Due to cyclone dust or product part again goes
into system and air goes to outer
environment(fig 3)

Temperature of Air
• At Outlet of cooler temperature remains 63
degree celcius.
• After cyclone temp was 60 ̊ c (Mention in
previous diagram).
Demo of BiOWiSH Odor
• First day 5000 ppm concentration of BiOWiSH odor
used for spraying.
• Dissolved 500 grm odor in 100 Ltr water.
• After 30 Min of Activation, filtered the solution and
filled it in spray pump for spraying.
Demo of BiOWiSH Odor
BiOWiSH odor sprayed at two different sites
of MBM.
• Grounded 120 kg MBM in a isolated room.
• Bags of MBM stocked.
Results of BiOWiSH odor
• After two days of dosing Results are very
