Double effect concentrator

This double-effect concentrator is a high-efficiency, energy-saving concentration equipment, widely used in pharmaceutical, food, chemical and other industries. The main body of the equipment consists of a first-effect evaporator, second-effect evaporator, condenser, vacuum system and related piping valves, all of which are made of high-quality stainless steel, with good corrosion resistance, to ensure long-term stable operation and comply with health standards.

One effect evaporator through the steam heating, so that the material in a vacuum state rapid evaporation and concentration, the secondary steam into the second effect evaporator as a heat source, to achieve the secondary use of energy, greatly improving the thermal efficiency, reduce energy consumption. The second effect evaporator further concentrates the material, and the condenser condenses and recovers the vapor produced by evaporation. The vacuum system maintains the vacuum environment inside the equipment, reduces the boiling point of the material, accelerates the evaporation speed, and at the same time effectively protects the heat-sensitive components from being destroyed.

The equipment is equipped with perfect temperature, pressure, liquid level and other monitoring and control systems, real-time monitoring and precise adjustment of operating parameters, easy to operate and safe and reliable. With its compact structure and small footprint, it is suitable for different scales of production needs, whether it is a small laboratory trial or large-scale industrialized production, it can efficiently complete the concentration task and help enterprises to improve production efficiency and reduce production costs.

I. Product structure and principle

Structural components:

condenserIt includes one effect evaporator and two effect evaporator, which are made of high quality stainless steel with good corrosion resistance and heat transfer performance. The internal structure of the evaporator is reasonably designed, which can make the material and heating medium fully contact and ensure efficient evaporation.
condensers: Used to condense the secondary vapors produced by evaporation into liquid for recovery, usually using a tube or plate structure, with high condensation efficiency.
vacuum system: It consists of vacuum pump, vacuum piping and related valves, which can maintain a stable vacuum environment inside the equipment, reduce the boiling point of materials and promote the evaporation process.
Pipes and valves: Connects components to achieve smooth flow of materials, steam, condensate, etc. The valve allows precise control of flow and pressure.
control systemEquipped with temperature, pressure, liquid level and other sensors, as well as automation control instrumentation, real-time monitoring and adjustment of equipment operating parameters

How it works:

The material firstly enters into the first effect evaporator, and is heated and evaporated by steam (or other heat source) under vacuum. The secondary steam generated into the second effect evaporator, as the heat source of the second effect evaporator, the material in the second effect evaporator for heating and evaporation, to realize the secondary use of energy and improve thermal efficiency. The concentrated material in the first and second effect evaporator reaches the set concentration and is discharged. The secondary vapor produced by evaporation is cooled and condensed into liquid in the condenser for recovery. The vacuum system maintains the whole process in a vacuum environment to reduce the boiling point of the material, accelerate the evaporation speed, and at the same time protect the heat-sensitive components from being destroyed.

II. Performance Advantages

energy-saving and efficientDouble-effect evaporation design, the reuse of secondary steam significantly reduces energy consumption, compared with single-effect concentrator can save energy about 50%. High evaporation efficiency can effectively shorten the production cycle.
quality assurance (QA): Vacuum low-temperature evaporation environment, can effectively avoid the destruction of heat-sensitive components, to maintain the active ingredients and flavor of the material, suitable for temperature-sensitive product concentration.
Excellent materialThe main parts are made of high-quality stainless steel, corrosion-resistant, easy to clean, in line with the hygiene standards of the food, pharmaceutical and other industries, to ensure product quality and safety.
easy operation: The automated control system can monitor and adjust the temperature, pressure, liquid level and other parameters in real time, and the operation interface is simple and easy to understand, which reduces the difficulty of manual operation and labor intensity.
operational stability: The equipment has a compact and reasonable structure, and the components have been strictly tested and quality inspected, which is stable and reliable in operation, easy to maintain, and can be operated continuously for a long period of time.

III. Application scenarios

Pharmaceutical industry: It is used for the concentration of extracts of traditional Chinese medicine and solutions of western medicine, etc. It can effectively retain the active ingredients of drugs and improve the quality and production efficiency of drugs.
Food industry: It is suitable for the concentration of fruit juice, jam, honey, plant protein, etc. It can keep the original nutrients and flavor of food, and is widely used in the production fields of beverages, condiments, bakery and so on.
Chemical industry: It can concentrate chemical solutions, organic solvents, etc., recover valuable components, realize the recycling of resources and improve production efficiency.
Other industries: It is also widely used in the fields of concentration of cosmetic raw materials, concentration of biological products, etc., to meet the concentration needs of different industries.

IV. Operation and maintenance

Operation:

Before starting the machine, check whether the parts are firmly connected, whether the valve opening and closing status is correct, and whether the meter is normal.
Turn on the vacuum system to establish a vacuum environment inside the unit.
Start the heating system and set the heating temperature of the first and second effect evaporators.
Slowly feed the material, control the feeding speed and liquid level to avoid material overflow or dry burning.
According to the material characteristics and concentration requirements, adjust the temperature, pressure, vacuum and other parameters, real-time monitoring of equipment operation status.
After the concentration is completed, first stop feeding, then turn off the heating system and vacuum system in turn, and finally discharge the concentrated liquid.

Maintenance:

1. Regularly clean the evaporator, condenser and other components to remove internal dirt and deposits to prevent affecting heat transfer efficiency and product quality.
2. Check the sealing performance of valves and pipes and replace worn or aged seals in time to prevent leakage.
3. Regularly calibrate temperature, pressure, level and other instruments to ensure accurate measurements.
4. Perform regular maintenance on key equipment such as vacuum pumps, adding lubricant, checking motor operation, etc., in accordance with the instruction manual.
5. When the equipment is out of service for a long period of time, the inside of the equipment should be cleaned and dried, and the equipment should be guarded if necessary.
