When ever people think of putting up a new biscuit plant , the first question which come s in mind is the plant output or capacity . This is important for design and project of new biscuit plant .Unit could be tons /hr or kg /hr of production . Biscuit output is required for material planning and plant specifications .
There different methods to calculate biscuit plant output as mentioned below
a . Baking time x with rows x columns in one minute from cutter /molder rpm. moulder and cutter have dies or cups as per biscuit shape and size .
b. Oven band surface area x baking time of biscuit oven .( tunnel oven )
Oven length and width depends upon the volume of biscuit to be produced
On the basis of capacity , Mixers and Packing machine are selected for line balancing
c. Mixing time with batch size processed in unit time
d. Number of packing machine used to pack with packet per minute for calculation .
Oven capacity (lbs/hr) = R x N x L 1/C x60/T
R = rows of goods per foot of band length
N = rows of goods across the band width
L = baking chamber length in ft.
C = count of baked biscuits per lb.
T = baking time in mins.maximum baked size of the coojie
To determine N & R.
Let W = actual product width in inches
D = maximum baked size of the cookie
S = spacing from centre to centre of adjacent rows
X = clear band space at each edge
Then, W = ( N x S ) - S + D +2X
or, N = W + S - D - 2X / S and R + 12 / S
Capacities of other machinery prior to the oven can be referenced to the oven capacity

Dear Sir,
ReplyDeleteI need a worked example of biscuit plant oven capacity calculation.
My company is only using R.P.M *no of rows of cup*no of column of cup*60*24*weight of 1 piece of biscuit/1000000.
Length of the oven, baking time, spacing btw biscuit piece and other parameters are not considered.
I think most of the biscuit manufacturers use above mentioned method to calculate oven out put
ReplyDeleteSir i need rpm caculation based on moulder rpm with gearbox for example my moulder running 867 rpm /gearbox ratio calculation. my moulser gear box ratio 34.3 motor 9.2 kw drive roler ratio 22.17
