What is double tube heat exchanger?

Double tube heat exchanger is a kind of Shell And Tube Heat Exchanger, which is a concentric circular casing connected by two different sizes of Seamless Tube (connected with Flange or others), the outer one is called shell process and the inner one is called tube process. Two different media can flow in the shell and tube process in the reverse direction (or the same direction) to achieve the effect of heat transfer.

What is the role of double tube heat exchanger in the tomato sauce production line?

In the sterilization section to quickly raise the temperature of the sauce to the prescribed temperature, in order to kill a variety of mold; cooling section to sterilize the sauce body quickly cooled, in order to maintain the freshness and color of the sauce; warming section to maintain the temperature of the material, ready for filling.

This section of the sterilization temperature is the key point of control. If the sterilization temperature does not meet the requirements, the product will be spoiled due to the presence of mold; if the sterilization temperature is too high, it will make the freshness and color of the product drop too much, and ultimately affect the quality of the product. The discharge valve at the outlet of the holding section is a three-way valve, when the sterilization temperature is detected to be too low, it will close the channel in the filling direction, and the sauce will re-enter the stirring tank, while automatically adjusting the steam valve opening, so that the water temperature rises, and the cycle of sterilization.
