EVALUATION OF THE INCREASE IN MATERIAL EFFICIENCY ASSOCIATED WITH THE SKIMMING OF FRESH MILK AT THE "CUBANACÁN PASTEURIZER"

Abstract

Introduction:
Given the need to increase the material efficiency of the Cuban dairy industry, it is necessary to have technological schemes at the Cubanacán Pasteurizer that take full advantage of the composition of fresh milk.
Objective:
To evaluate the increase of material efficiency associated with the skimming of fresh milk, proposing a more efficient and sustainable technological scheme, establishing the demands for materials and the availabilities of finished products in the new scenery.
Materials and Methods:
An efficient and sustainable technological scheme was proposed with one variant using skimming of fresh milk increasing the quantity and acceptance of the elaborate assortments, and another traditional variant processing fresh whole milk. The material balance was carried out considering two typical stages: drought and spring. The flows and compositions of all process streams were determined in both variants.
Results and Discussion:
The proposed scheme allowed generating productive strategies and establishing analysis subsystems that facilitated the balance of materials. The composition of the new process streams constitutes important information that was not available. The availability of milk to divert to other plants and the overall production depend more on the stage of the year than on skimming, but the latter makes the process more flexible and increases the use of the composition of the main raw material.
Conclusions:
Milk skimming does not appreciably increase the total production of the Cubanacán Pasteurizer, but it does diversify its productions towards assortments with better acceptance and added value that make its management more sustainable.
