Describe how jet heaters work and where they are applied (processes).
A: The jet heater is mainly composed of nozzle, inhaler, and expansion tube. When the material passes through the nozzle at high speed, its kinetic energy increases, the static pressure energy becomes smaller, resulting in negative pressure in the suction chamber, steam sucking into the chamber, the material and steam are fully mixed in the throat of the diffusion tube, the material is heated, the speed in the diffusion section is gradually reduced, the pressure is also increased, and the kinetic energy is converted into static pressure energy and discharged from the outlet.
Jet heaters are suitable for places where materials are heated continuously, such as continuous sterilization.
