# Daily Manufacturing Report (DMR) Cum Chemical Control (Sugar Lab) Calculation Sheet

## Formulas for Calculating Sugar Industry Daily Manufacturing Report (DMR)  With Simple Online Calculator

### Fundamental formula :

In put = out put

Cane +   Added water  = Gross mixed juice +   bagasse

If cane is 100  than 100 + Added water% cane = M. J. % cane + Bag. % cane.

Drit correction % M.Jc

Quantity of Drit in MT = Gross mixed juice x Drit correction % M.Jc

Net M.Jc in MT = Gross mixed juice – Qty of Drit in MT

( Note: Here to be take Net M.Jc in MT)

### Sugar balance :

Sugar (pol) in cane =Sugar (pol) in mixed juice +  Sugar (pol) in bagasse

Sugar (pol) % cane = Sugar (pol) in M.jc % cane + Sugar (pol) in Bagasse%cane

### Mill Extraction (M E).

The quantity of sugar extracted in the mixed juice per 100 sugar in cane i.e. percentage of sugar extracted in the mixed juice out of total sugar in cane.

### Fibre % Bagasse :

Bagasse  =  fiber + Moisture  +  Brix

Fiber= Bagasse   – Moisture   – Brix

If bag =100 Then,   fibre % bag = 100  –  moist %bag –   Brix % bagasse

Moisture % bag & Pol% Bag. are determined directly by analysis of  bagasse.

Brix% Bagasse

While determining brix % bagasse, it is assumed that purity of residual juice in bagasse is same as purity of last expressed juice.

Fiber % cane:

### Noel Deer and Mittal

Noel Deer proposed formula to reduce the extraction to common basis of 12.5% fiber, that is called as Reduced Mill Extraction (RME Noel Deer)

For unit juice in cane ‘e’ is mill extraction.

Then juice lose in bagasse will be (1 – e )

Assume that unit cane contains ‘f’ fiber, then unit cane contains (1-f) juice.

Therefore juice lost per unit cane will be (1-e) (1-f).

The unit cane contains ‘f’ fiber.Therefore juice lost in bagasse per unit fiber will

Where

Pbc = Pol in Bag. % cane,  Pc = Pol% Cane,  Fc  = Fiber. % Cane.

### Clarification Factor:

Good clarification means better sugar, less losses and unsatisfactory clarification means (results in) production of inferior quality of sugar with poor keeping quality and higher manufacture losses.

N .S. in M.J.% cane = Bx.% M.J. x M.J.% cane  –  Pol% M.J.  x  M.J. % cane.

Pol in CJ % cane =   Pol in M.J. % cane –  Pol in F.C. % cane.

N.S. in C.J. % cane = Bx.in C.J.% cane –  Pol in CJ % cane

Non sugars removal %cane = Non sugars in M.J % cane – Non sugar in c.Jc % cane

Clarification Factor = 100 – Clarification efficiency

### Theoretical Final Molasses % cane :

Non Sugars % F.M = Brix % F.M – Pol % F.M

### Expected Recovery

S = Purity Of final product(sugar)

J = M.Jc Purity

M = Final Molasses Purity

Expected Recovery = Pol in C.Jc % cane x SJM factor – Unknown losses  (Note:Here to be take estimated unknown losses )

### Pol balance

Pol % cane  =Pol in M.J.% cane+  Pol in Bag % Cane

(Note : Here to be take Theoretical Final Molasses % cane)

(Note : Sugar % cane means recovery%cane )

Total Losses   =Pol % cane  –   Pol in Sugar % cane.

Total Losses =   Losses in (Bag. + F.C  + F.M. + Unknown)

Unknown losses = Total losses – Determined losses

Unknown losses = Total losses –  Losses in (Bag. + F.C  + F.M.) (Note: It may differ 0.01 to 0.02 from estimated unknown losses)

### Boiling House Control

#### E.S.G ( Equivalent Standard Granulated) Factor :

a) The term Standard Granulated used to indicate the finest commercial product and considered as equivalent to pure sugar

b) The term E.S.G is used to indicate the finess of the commercial sugar and denoted by sugar(product) in very clean form. The commercial sugar is expressed in terms of standard granulate.

c) E.S.G form for commercial sugar apply S-J-M formula where S=100, M= actual purity of molasses and J= purity of sugar.

#### Boiling House Recovery (BHR)

The value of ration of sucrose (pol) in commercial sugar produced to the sucrose (pol) in mixed juice.

#### Basic boiling house recovery (BBHR):

The theoretical Boiling House Recovery as calculated by S-J-m formula in which J in purity of M.J. and S=100 and m=28.57

#### Reduced Boiling House Recovery (Noel Deerr)

Where Mv  =Virtual Final molasses purity

Where R = BHR = sugar in pol % cane / Pol in M.Jc %cane

J= M.Jc Purity (Unit value)

#### Reduced Boiling House Recovery (Gundurao)

Where   r  =  BHR

K   = N.S. in clear juice % cane /  N.S.in M.J.% cane

M = Final molasses purity

J = M.Jc Purity

In the next revision of the article will provide all formulas related to chemical control calculation.

I think, in this calculations, formula used for Clarification Efficiency is wrong. The correct formula should have been as,
Clarification Efficiency = Non Sugars in Clear Juice % Cane / Non Sugars in MJ % Cane X 100

Sir, Please post the calculation DMR for sugar in case of B Heavy and Syrup diversion for Ethanol with different ratios

will be provided

Recovery in case of BH diversion and Syrup diversion for ethanol is same as tradition method, only thing your have to subtract available sugar in Syrup % cane from Original recovery to get net Plant recovery., Pol balance includes Available sugar in Syrup and available molasses in Syrup., In case of B-Heavy in place of FM take BH purity for calculation.,
