About this deal
In regard to color, the pasteurization process does not have much effect on pigments such as chlorophylls, anthocyanins, and carotenoids in plants and animal tissues. Developed countries adopted milk pasteurization to prevent such disease and loss of life, and as a result milk is now considered a safer food.
When the measured value does not equal the set value, the regulator adjusts the signal to the regulating device. Now, the MilkTaxi permits reliable feeding and weaning depending on calf age – which was only possible with a calf feeder before.Actuation is essentially as follows: a pneumatic signal from a controller is supplied to a proportioning device, a positioner, at the top of the valve. To achieve this, the milk is normally heated to not less than 72 °C for at least 15 seconds and then cooled rapidly. According to the Centers for Disease Control, between 1998 and 2011, 79% of dairy-related disease outbreaks in the United States were due to raw milk or cheese products.
The setting of the regulating device, valve plug position or motor speed, determines the amount of the regulated process parameters. In plate heat exchangers, the connection plates between the sections are provided with inlets and outlets for product and service media.
