Triple-Effect Evaporator

Triple-Effect Evaporator | Multi-stage, Series-Connected, Energy-Efficient, Low-Temperature Vacuum Concentration Equipment for Large-Scale Production Lines

💡 The triple-effect evaporator is a highly efficient, energy-saving vacuum concentration system designed for large-scale batch production. It features a three-stage cascade evaporation structure with secondary steam recycled and reused at each stage, achieving energy savings of 60% or more compared to single-effect systems. Its low-temperature, continuous operation fully preserves the activity of heat-sensitive materials, making it suitable for large-scale liquid concentration production lines for traditional Chinese medicine, plant extracts, food, and health supplements.

I. Product Overview

Triple-effect evaporators are commonly used in large-scale production.High-Efficiency, Energy-Saving Vacuum Concentration Equipment, featuring a multi-stage series evaporation structure comprising first-, second-, and third-effect stages, where the secondary steam generated in the preceding stage is sequentially used as the heat source for the subsequent stage, enabling multi-stage heat recovery and significantly reducing steam and cooling water consumption. The equipment operates continuously under vacuum and at low temperatures. The feed solution is heated for a short duration and undergoes gentle, stable heating, effectively protecting heat-sensitive active ingredients. It is widely used in large-scale evaporation and concentration processes across industries such as traditional Chinese medicine, plant extraction, food, and health supplements.

II. Structural Configuration Description

The equipment consists of a first-effect heating and separation chamber, a second-effect heating and separation chamber, a third-effect heating and separation chamber, a condenser, a condensate recovery tank, a vacuum system, piping and valves, and a complete automatic control system. The main types are divided intoExternal-circuit, falling-filmTwo configurations, fully enclosed, sanitary-grade, integrated design:

✅ Three-stage cascading evaporation structure

First-, second-, and third-stage sequential heat exchange, combined with secondary steam recirculation and recovery, significantly improves thermal efficiency and substantially reduces steam and cooling water consumption.

✅ High-efficiency multistage gas-liquid separation unit

Each stage features independent demisting and separation, completely preventing material carryover in the feed liquid. This results in high recovery rates for organic solvents such as ethanol and reduces raw material loss.

✅ All-stainless-steel, food-grade housing

The interior and exterior surfaces of the cylinders and piping are mirror-polished, leaving no hygiene dead zones; they are corrosion-resistant and easy to clean, and comply with cleanroom production standards.

✅ Expandable full suite of automated support modules

An automatic defoaming system, continuous feed and discharge mechanisms, CIP (Clean-in-Place) systems, and fully automatic level/temperature control and interlock modules can be installed as needed.

III. Key Features

✅ Multi-stage heat recovery cycle, offering significant energy-saving and consumption-reduction benefits

Three-effect steam cascade reuse saves 60% or more in energy compared to single-effect concentration equipment; long-term mass production can significantly reduce operating costs for steam procurement and cooling water and electricity.

✅ Gentle evaporation under vacuum at low temperatures preserves the activity of heat-sensitive materials

The entire process operates under negative pressure and at low temperatures, minimizing the time the feedstock is exposed to heat and preventing the high-temperature oxidation and decomposition of active ingredients in traditional Chinese medicine, fruit juices, and biological raw materials.

✅ High throughput, suitable for continuous, large-scale mass production

The entire unit features high evaporation efficiency and a large processing capacity, supporting 24/7 uninterrupted continuous concentration, and is suitable for large and medium-sized standardized production lines.

✅ Smooth material flow, low risk of scaling and coking

The stable, circulating flow path design reduces localized material buildup and prevents sticking to the walls and scaling, resulting in less work required for equipment shutdown cleaning and routine maintenance.

✅ Materials that comply with hygiene standards and meet GMP food regulations

The entire unit is manufactured from 304/316L food-grade stainless steel and polished without any dead corners, fully complying with pharmaceutical GMP and food contact safety standards.

✅ Multi-mode intelligent control for stable and reliable operation

Supports two operating modes: semi-automatic manual operation and fully automatic PLC interlock control. Features automatic adjustment of temperature, vacuum, and liquid level, as well as fault alerts, ensuring stable operation.

IV. Scope of Application

Widely used in the pharmaceutical, herbal extraction, food, health supplement, daily chemical, and fine chemical industries, it is designed for low-temperature vacuum continuous concentration of aqueous solutions, alcohol-based extracts, and various heat-sensitive raw materials.
