Input to the oven is the heat energy from combustion of fuel ( lpg , cng , ldo/hsd/ , electrical ) . One must evaluate the fuel options available for the factors such as
- Availability of fuel
- Cost per unit
- Calorific Value of the fuel
- Maintenance cost on the Burners
Hence the fuel with best value ( calorific value per unit x net cost per unit ) should be sourced .
Now Oven out put in energy terms are
Heat Loss during baking of biscuit
Heat Loss during evaporation of moisture - Flour quality plays important role plus the mixing quality
Heat Loss through flue gas - Combustion generates flue gases which escapes through stacks . Heat recovery system can be installed recover this heat .Air to fuel ratio has to be checked so as to prevent excessive heating going out as flue gas .
Heat Loss through radiation - Biscuit Ovens have either duct s or Pipe s through which hat air circulates . Considerable heat are lost in these mediums . Good Insulation can be provided to minimize the loss of heat through Biscuit Oven body
Heat Loss in Band Heating - Band re heating s are now days incorporated by manufactures by providing enclosure at the bottom through which the bands returns to the feeding end .
For majority of the Baking Ovens it has been seen that it utilise' s only 40 - 50% of the Heat Input . Efforts has to be made for optimisation of heat energy

ReplyDeleteto cut down fuel cost in biscuit industry
Dear Manoj ,
ReplyDeleteThnx for your comment
we would appreciate if u can tell us more on gasifier and tell us where all you have installed bio mass gasifier in biscuit industry
Dear Subodh,
ReplyDeleteThanks for your kind interest in biomass gasifier.
Gasifier can be used in biscuit industry to replace existing ldo/fo/diesel in their , which in result can give saving of fuel cost upto 50%.
Please find attached our product catalogue for your kind reference.
we have installed our system in various biscuit plant,
few of them are
Ravi food , Hyderabad
Raj Agaro Hyderabad
Sururchi Biscuit Kolkata
Satya Biscuit , BHOPAL
Suraj Biscuit, Rajkot
e.t.c
If you need any further details please let us know.
Regards
Thnx Manoj for submitting companies names which are using gasifier as alternate to ldo/fo/hsd .
ReplyDeleteManufacturers can now contact these units to verify the working of gasifier in biscuit plants .
Infinite Energy are the manufacturer of these gasifier plants
Can we use exhaust heat from zone 4 (250 degree) to zone 1,2,3 which is having low temp than zone 4 ,is it applicable in real Biscuit oven.
ReplyDeletePlease suggest me...

Dear Hari ,
DeleteWe can utilize heat from zone 1/2/3/4 to eliminate burners from zone 6 or zone 5 thus resulting in fuel saving
