Oil
Spraying Machine
The Oil Spraying Machine is used to
spray fine most of edible oil on
the top and bottom of hot biscuits
coming out of oven before being
transferred to cooling conveyor.
Biscuit
Baking Oven:
-
Construction:
The oven body consists of
steel steamtight tunnel with
equally divided zones of the
radiators. Stainless steel
expansion joints are provided
between these zones in order
to eliminate the expansion of
the oven section. The
inspection doors are provided
for inspection of the baking
goods during the process.
-
Firing
Chambers: The complete
chamber will be insulated with
minerwall filled from outside
to conserve heat and increase
efficiency. The fully
automatic imported burner
shall be fitted to the chamber
and the temperature shall be
controlled by automatic
temperature controller on the
control panel.
-
Insulation:
The complete oven will be
covered with 10" thick
mineral wool insulation from
top, bottom and the sides. The
bottom portion of the oven at
the sides will be covered with
CRC sheets for the conveyor
protection and to avoid heat
loss.
-
Baking
System: The baking in the
heating chamber takes place by
radiators located under and
above the wire mesh band which
distribute heat for uniform
baking. The recirculation
heating gases of these
radiators can be controlled
for each zone separately. The
closed recirculation system is
having slight vacuum so that
combustion gases can not enter
into the baking chamber. The
ventilating fan is for
circulation of the heating
gases through the
recirculation system and
thermostatically controlled
burners provide the set
temperature of the heating
gases.
-
Fans:
All the circulating fans are
fabricated from M.S. &
S.S. and will be well balanced
to avoid vibration and will
give noise free operation in
high speeds.
Cooling
Conveyor & Stacking Machines:
Cooling conveyor is made in a
modular construction of 2.5 Mtrs.
long and connected together to
form the required length. The
supporting side channels are
fabricated from 3mm thick M.S.
sheet.  
Idle rollers are spaced at 750mm
apart on conveying direction and
1700mm on the return direction.
All the idle rollers are of 48mm
dia, mounted on 6004 ZZ deep
groove ball bearings with grinding
finish and hard chrome plated for
hygienic conditions.
As you know very well practically
about the droppings of oil from
the cloth due to rubbing of cloth
against tie angles when producing
high fat biscuits. To minimise
this we replaced the all tie
angles also with idle rollers.
This might costs little extra, but
you can maintain hygienic
conditions at working area.
Drive drums are two no's. of 220mm
dia and projections are made on
the surface of drums to minimise
slip or covered with friction grip
rubber tape. Manual tensioning and
tracking are provided.
You can rely only on feeder table
to stack the oil sprayed biscuits
which does not require more travel
after oil spraying.
Sugar
Grinder:
-
Application:
The machine is used to granule
(crystal) sugar to make it in
powder form for using in
biscuit recipe. 
-
Design:
Hammer Mill type, body of the
machine is fitted on a sheet
metal box/container/receiver
with one air exhaust balloon.
The driving motor is fitted on
the top of the box. In case of
auto feeding a bucket elevator
is fitted at one end of the
box.
-
Output:
10 Kg/min. (icing sugar)
-
Feeding:
Automatic
-
Power
Load: 5 HP for grinder,
1 HP for auto feeder with
built-in control panel.
Rotary
Moulder: The dough to be
moulded is fed into the hopper and
a forcing roller forces the dough
into the cavities of the moulding
roller made out of gun metal,
uniformly engraved and coated with
food grade Teflon. Excess dough is
cleared with a knife, which is
held by a holder made from tool
steel, to ensure uniform filling.
 
An adjustable rubber roller
conveying the discharge cotton
web, presses it uniformly against
the moulding roller for perfect
transfer of molded pieces from the
moulding roller on to the web.
The purpose of three drives is,
speed of the forcing roller
influences the density of dough
forced in to the moulding cavity.
The speed of the die roller
influences the production speed.
The discharge web speed influences
the shape of the biscuits produced
along the web or across the web.
