This equipment operates under vacuum pressure reduction conditions, achieving low-temperature and efficient concentration by reducing the boiling point of the feed liquid. The material liquid is heated and evaporated in the main body of the concentrator. After removing the entrained liquid foam through the gas-liquid separator, the secondary steam enters the condenser for condensation and recovery. Non condensable gases are extracted by the vacuum system. The concentrated material can be discharged with the assistance of a mixer and flipping mechanism to ensure the smooth discharge of high concentration materials.
