Objectives of the Project:

• Know the different stages of cow milk production

• Know how we can improve the quality of the cow milk

• Know the advantages of automation in food production process

• The heavy manual labor were taken over by machines. The heavy manual labor were taken over by machines. • MechanizationMechanization, together with the rapid expansion of , together with the rapid expansion of

production capacity, also led to increase in the number of production capacity, also led to increase in the number of operations that had to be executed. operations that had to be executed.

• More valves had to be operated, more motors had to be More valves had to be operated, more motors had to be started and stopped. The timing of individual operations started and stopped. The timing of individual operations also became also became criticalcritical. Operating a valve too soon or too . Operating a valve too soon or too late, for example, could lead to product losses. late, for example, could lead to product losses.

• Every Every malfunction malfunction in the process, and every operator in the process, and every operator error, could have serious economic consequences. error, could have serious economic consequences.

• Depending on regulations, the design of process lines for Depending on regulations, the design of process lines for pasteurized market milk pasteurized market milk varies varies a great deal from country a great deal from country to country and even from dairy to dairy. to country and even from dairy to dairy.

• Fat standardization (if applied) may be executed in-batch Fat standardization (if applied) may be executed in-batch before pasteurization or in-line where the standardization before pasteurization or in-line where the standardization system is integrated into a pasteurization unit.system is integrated into a pasteurization unit.

• A common requirement in all countries is that the heat A common requirement in all countries is that the heat treatment must guarantee significant treatment must guarantee significant reductionreduction of of spoiling microorganisms and destruction of all pathogenic spoiling microorganisms and destruction of all pathogenic bacteria, without the product being damaged.bacteria, without the product being damaged.

Homogenization Process

8

Homogenization Process

• Homogenization is to reduce the size of the fat globules in the milk, in order to reduce or prevent creaming.

• Homogenization may be total or partial. • Partial homogenization is a more

economical solution, because a smaller homogenizer can be used.

Cow milking is ready

Filling milk tanks

Milk feeding pump filling the pasteurization unit after milk filtration

When Pasteurization done The deareation process ll begin by exerting high Pressure CinAnd Cout (Start and end the process)

Homogenization start by adding other Ingredients for a preset time. Bottles filling processStart filling 3 bottles at time

The Bottles are filled with in a boxes of 6 ,the system will stop production when it reaches 600 boxes per day

Conclusions

• The most important advantages of automation are:

-Food safety -Consistent product quality -Reliability -Production economy -Flexible production -Production control -Trace ability

11

Conclusions

• PLC can reduce the cost of milk production by reducing the number of hand labors and replaced them by smart machines and sensors
