In order to ensure accurate and timely management of manufactured products, with clear tracking of raw material movements—milk and cream—the following main elements must be taken into account:

DAILY MANAGEMENT:

=INITIAL STOCK= highlights the initial stock of the day in liters of milk (whole, standardized, skimmed) and kg of fat, both in terms of quantity parameters in liters or kg, fat units, kg of raw material, as well as their physico-chemical parameters for % fat, % SUT, density and the corresponding automatic calculations—within the factory’s management system;

=INPUTS= highlights the day’s inputs in liters of milk (whole, standardized, skimmed) and kg of fat, both in terms of quantity parameters in liters or kg, fat units, kg of raw material, as well as their physico-chemical parameters for % fat, % SUT, density and the corresponding automatic calculations—from the field, from other factories, or from cream separation and standardization processes;

=RAW MATERIAL CONSUMPTION= highlights the day’s consumption of raw materials allocated for the production of manufactured products according to orders, in liters of milk (whole, standardized, skimmed) and kg of fat, both in terms of quantity parameters in liters or kg, fat units, kg of raw material, as well as their physico-chemical parameters for % fat, % SUT, density and the corresponding automatic calculations;

=FINAL STOCK= highlights the final stock of the day in liters of milk (whole, standardized, skimmed) and kg of fat, both in terms of quantity parameters in liters or kg, fat units, kg of raw material, as well as their physico-chemical parameters for % fat, % SUT, density and the corresponding automatic calculations—within the factory’s management system;

=LOSSES= highlights the losses recorded during the technological process, as the difference between total inputs and total outputs, across the various analysis elements in the file: liters of milk, kg of fat, kg of SUT, kg of milk, fat units, etc.

The connections between the elements described above are reflected in the general formula:

TI = TF …… = SI + I = SF + E + P

WHERE:

Total In = Total Out  TI = TE

Total Initial = Initial Stock + Input  TI = SI + I

Total Final = Final Stock + Outputs + Losses  TE = SF + E + P

The essential elements of a material balance, in the technological and professional sense, are given by the presented formulas, with examples from the daily management file. The elementary formulas of the daily balance, which must be taken into account, are described.

In practice, the formulas provided represent key elements of the material balance.

THE PRESENTATION OF A COMPLETE MATERIAL BALANCE IN DAILY MANAGEMENT can be carried out through an Excel table or by transferring the table values into complex computerized management programs.
