Single effect concentrated evaporator

Overview of single-effect evaporator:

  Evaporative concentration is the most widely used concentration method in syrup factories and food factories.Use evaporation and concentration equipment to heat the material, so that the volatile part of the water and other media in the boiling point temperature of the material constantly from liquid to gas, will be vaporized when the secondary steam is constantly eliminated, so that the concentration of the product continues to increase until the concentration requirements.

The evaporator consists of an evaporator (with heating interface and evaporating surface), a condenser and an air pump.Owing to the nature of the various solutions, the requirements of the evaporation conditions vary widely, evaporation and concentration equipment in the form of so many, according to the different classification: 1, atmospheric evaporative enrichment equipment, 2, vacuum evaporation and concentration equipment membrane evaporation concentrator, 3, 4, falling film evaporation and concentration equipment 5, thin-film evaporation concentrator, 6, the central circulation tube evaporative enrichment equipment, 7 evaporation and concentration equipment and so on, the coil type!

The single-effect equipment consists of vertical tube heater, evaporator, condenser and pipeline valve, etc. The vacuum system can be equipped with water jet or vacuum pump with other equipment. The main technical parameters are as follows:

Evaporation (Kg/h water) -- 150/300/500/1000

Heating steam pressure (MPa) -- 0.05-0.09

Steam consumption (Kg/h) -- ~1000

Water consumption (t/h) -- ~15t(can be recycled after cooling)

Classification of single-effect evaporator: single-effect falling-film evaporator, single-effect forced circulation evaporator, thin-film evaporator, single-effect external circulation evaporator, etc.

Single effect evaporator application

Single-effect concentrated evaporator is suitable for the concentration of materials such as traditional Chinese medicine, western medicine, starch, sugar, food and dairy products and the recovery of industrial organic solvent (such as alcohol).

Characteristics of single effect evaporator

1. Alcohol recovery: high recovery capacity, adopting vacuum concentration process.Compared with the same equipment of the old type, it can increase productivity by 5-10 times, reduce energy consumption by 30%, and have the characteristics of small investment and high recovery efficiency.

2, concentrate: single effect concentrator adopts the outside heating natural cycle and vacuum negative pressure evaporation, a combination of fast evaporation and concentration ratio can reach 1.3, the liquid in a state of full seal without the foam concentration, with a single effect concentrator concentrated liquid, with no pollution, the characteristics of the ingredients in thick, and convenient cleaning (open heater cover can be cleaned up and down).The single-effect concentrator is simple to operate and occupies a small area.The heater and evaporator adopt stainless steel insulation structure, and the outer insulation layer is made of stainless steel sheet, and the surface is treated with mirror or matt.

Triple effect evaporator 

Three effect concentrated evaporator

Three effect evaporator overview

Triple effect evaporator is a single effect evaporator in series on the double effect evaporator.

This device is a new type of high-efficiency and energy-saving vacuum evaporation and concentration equipment, which features as follows:

1. Multiple use of primary steam and effective heat preservation of superheated self-evaporator of condensed water greatly reduce the consumption of heated steam which is less than 0.4kg when 1Kg of water is evaporated.

2. The evaporator and condensate storage adopt overlapping structure, and the whole set of equipment occupies a small area.

3. Adopting advanced-flow evaporation process based on external heating or natural circulation, with large circulation degree, high evaporation speed, short heating time, easy coking and convenient cleaning.

4. The use of vacuum evaporation operation not only has a large evaporation capacity, but also the material can evaporate at a lower temperature, which can meet the requirements of concentration of heat-sensitive materials.

5. Adopt the new type of air separation device, no running material phenomenon, high product yield.In a word, this device is a new type of high efficiency and energy saving concentrated equipment, which can be widely used for high concentration concentration of materials in chemical industry, medicine, food and other industries.

6. Energy saving benefits, calculated according to sjn-1000, save about 54,000 tons of steam, 14 tons of water and 130,000 KWH of electricity annually, which is equivalent to 200,000-250,000 yuan (compared with single effect).

7. Three-effect concentrated evaporator adopts the negative pressure external heating natural circulation evaporation mode, with fast evaporation speed and large concentration ratio, up to 1.25-1.4 (general Chinese medicine extract).

8. The three-effect concentrator adopts the two-effect simultaneous evaporation, and the secondary steam is used. Compared with the single-effect concentrator, the total energy consumption is reduced by 67%.

9. Multi-functional operation features :(1) it can recover 80% alcohol concentration;(2) single effect, double effect and three effect can be repeated and pot paste collection;(3) intermittent and continuous feeding.

10. The contact parts between the three-effect concentrated evaporator and the materials are made of stainless steel, which conforms to GMP standard.Beautiful appearance.Outside the heater and evaporator are equipped with insulation layer, which is made of stainless steel sheet, and the surface is treated with mirror or matt.
