The diagram given illustrates the multi-stage process of making yoghurt.
Overall, it is clear that the production of yoghurt requires four stages, starting with mixing four ingredients and ending with packaging to be distributed to consumers.
First of all, the process begins with combining four ingredients, which consist of stabilizers, dry milk, sugar, and milk, and pouring into a hygienic stainless steel vessel, where the mixture is ready to be heated to 85 degrees Celsius. After the pasteurization stage is completed, the blend, which starts the homogenization phase, is cooled to 42 degrees Celsius.
Following the first two steps, the mixture is stirred while another ingredient called cultures is put into it. The blend then continues to decrease to 7 degrees Celsius and goes through the fermentation process to become yoghurt. In the final step, the complete product is packaged into individual containers to be sold to customers.
