Introduction to the technological process of milk production equipment

1. After filtering the fresh milk, feed it into the heating tank. When it is preheated to 50-60 degrees, add one-half of the white sugar used for production to the milk, heat it up to 70 degrees, homogenize it once, and then continue to heat it to After keeping at 80°C for 10 minutes, start to cool down to 43-45°C and keep the constant temperature. Add 3% of the fresh milk amount for production into the milk, and ferment at constant temperature for 3-5 hours. The pH of the fermented milk is controlled at 3.8- 4.15 is good, stop fermentation. Quickly cool to below 30 degrees, stir slowly to prepare

2. Preparation of stabilizer mixture: mix 1/2 of the white sugar used for production with stabilizer, meringue, potassium sorbate, dry mix and mix, and sprinkle into 80-85 degrees hot water while stirring to prevent powdery For bonding, if there is a colloidal block, it can be broken through a colloid mill. If the stabilizer mixture is soaked for 3-5 hours in advance, the effect will be better. Then cool it to 25-35 degrees.

3. Mix the fermented milk and stabilizer mixture evenly at low temperature, and measure its acidity. If the pH is above 4.2, use 2/3 side of the citric acid diluent (5% of the production water is used to dilute the citric acid) Sprinkle it into the material liquid while stirring to measure its acidity until the pH of the material liquid reaches about 4. 4. According to the fragrance type, sprinkle the spices into the material liquid and stir it evenly, and put it into the storage tank for packaging. The packaged product is quickly sent to the cold storage for post-cooking, and it can be put on the market the next day.

5. The milk filling machine is a kind of equipment on the production line. The technology used in the milk production line includes refrigeration tanks, storage tanks, mixing tanks, homogenizers, high-temperature sterilization machines, plate heat exchangers, finished tanks, filling machines, It is an integrated multifunctional production unit, which can be directly connected to the filling machine for filling from the system. The equipment has a reasonable structure and beautiful appearance, which can greatly save the space of the production site. One worker can operate and produce, low-cost maintenance, standardization of parts, and localization of substitutes. The multifunctional milk beverage production line can produce fresh milk, pasteurized milk, yogurt, fruity yogurt, fruit juice, blended juice, tea beverage, ice cream, etc.
