Jacket Reactor GMP

The jacket design consists of an outer jacket which surrounds the vessel. Heat transfer fluid flows around the jacket and is injected at high velocitythrough nozzles. The temperature in the jacket is regulated to control heating or cooling. The single jacket is probably the oldest design of external cooling jacket.

Milk cooling

Divide the cooling fluid flow rate by the milk flow rate to determine the ratio. In our example this would be 1.5 divided by 0.5 = 3. Therefore the cooling fluid flow rate is 3 times the milk flow rate – a ratio of 3:1. This ratio would indicate that the problem lies elsewhere as it is in the correct range.
