Product Details

Product Introduction

Vacuum concentration is a process in which the material is heated under reduced pressure, causing the moisture to evaporate rapidly and form vapor, while the resulting secondary steam is continuously removed. This continuously increases the concentration of the product until it reaches the desired level. The equipment used to carry out this process is known as vacuum concentrators. The three-effect vacuum concentrator is suitable for liquid evaporation and concentration, as well as for recovering valuable components, in industries such as traditional Chinese medicine, Western pharmaceuticals, and light chemical manufacturing.

Working principle

The steam generated in the first effect is pressurized and then conveyed to the second‑stage steam drum as a heat source, and subsequently to the third‑stage steam drum for the same purpose. With three sequentially operated steam drums, this configuration is referred to as a triple‑effect evaporator. After steam is introduced into the first effect, it releases heat and condenses into liquid; the resulting secondary steam then enters the second effect, where it heats the feed liquid and subsequently condenses. The secondary steam produced in the second effect flows into the third effect, again heating the feed liquid, and after releasing its latent heat, it condenses and is discharged.

Product Structure

The triple-effect vacuum concentrator consists of a first-effect heater, a first-effect evaporator, a second-effect heater, a second-effect evaporator, a third-effect heater, a third-effect evaporator, a shell-and-tube condenser, a liquid receiving tank, a buffer tank, a water-ring vacuum pump, a circulating water tank, and other components.

Product Features

1. Vacuum concentration lowers the boiling temperature of raw materials during evaporation, thereby avoiding high‑temperature processing and helping to preserve their nutritional components; it is particularly well suited for concentrating heat‑sensitive materials such as milk.
2. The reduction in the boiling temperature increases the temperature difference between the heating steam and the feed material, thereby enhancing the heat transfer rate, accelerating the evaporation process, and boosting production capacity.
3. Conditions have been created for utilizing secondary steam and conserving energy, such as in double-effect and multi-effect concentration processes.
4. Vacuum concentration is carried out under low-temperature conditions, with a small temperature difference between the equipment and the surrounding environment, thereby minimizing heat loss during operation.
