EVAPORATORS AND ITS TYPES

What is an Evaporator??

An evaporator is a device used for the process of turning the form of a substance from liquid to gaseous form or vapor and the process is known as evaporation.

Types of Evaporators:-

Falling Film Evaporators:-

The falling film evaporator is a type of evaporator which is used for heat exchanger. It consists of a vertical shell and a tube heat exchanger. The concentrated liquid is fed at the top of the tube and then flows down to the surface tube as a thin film. As it gets heated further, the vapors get generated. It increases the heat transfer and the vapor and liquid get separated further.

Rising Film, LTV (Long Tube Vertical) Evaporators:-

The rising film evaporator is very similar to the falling film evaporator. It’s just the opposite of falling film. It also consists of a vertical shell and a tube heat exchanger and it is also used for heat exchanging. The concentrated liquid is fed at the bottom of the tube. As the heat increases further the vapors get generated and lift the liquid upward. As a result the vapor and liquid get separated further.

Forced Circulation Evaporators:-

Force circulation evaporator is a type of evaporator which is used to separate mixture which is not possible by normal evaporating unit. In normal circular evaporator the velocity of liquid flow is 0.3 to 1m/s but forced circular evaporator increases the velocity of liquid flow to 2 to 6m/s. It contains a circulation pump and because of this it is used for both heat exchanger and flash separation. It separates the mixture without using normal conventional boiling. It consists of a vertical shell and heat exchanger tube with a centrifugal pump.

Plate Evaporators:-

Plane evaporators consist of a plate and frame heat exchanger and are mainly used in food and beverage industry. Plate evaporator is a type of evaporator in which a thin film of liquid is passed and flows between the plates for the process of evaporation. It is typically used for fruit juices, fruit puree, syrup, coffee, milk.

Thermal Vapor Recompression(TVR):-

Thermal vapor recompression evaporator is a type of evaporator which is used as a thermo compressor to reduce the steam required for the process of evaporation. A vapor steam is compressed to a higher temperature and pressure by a steam jet pump.

Mechanical Vapor Recompression (MVR):-

Mechanical vapor recompression is a type of evaporator in which the water vapor is compressed which results in rise of temperature and pressure. The rise in temperature makes the temperature difference between the vapor and the fluid. The further heat transfer results in heat exchanger. The compressed vapor is again fed back to generate more steam. This is energy efficient and energy recovery process.

Cruciality of Evaporator- thermal recompression in processing industry

What is an evaporator?

          Evaporator is a device whose job is to make the material evaporate, or enter in its gaseous form. They have a multiple applications which ranges from agriculture to waste management. Industries that are dependent on continuous supply of chemicals and fluids are generally equipped with evaporator systems.

Uses of evaporator system

       Evaporator systems are something that have a very wide area of application. As they are very efficient, therefore they are most common in processing industry. Evaporator systems can also be found in very low temperature applications in the food and pharmaceuticals industries. There is another industry where evaporators have extensive application i.e. waste management, they depend on evaporators for variety of mechanical recompression procedures.

          Evaporator systems are configured in such a manner that they are able to serve a wide range of practical uses. That is a reason for which they are being required in many different industries as they are the versatile solution to many critical issues.

          Various food manufacturing units put the processing structure of evaporative systems, mechanical recompression under their service. Opinions of designers and manufacturers of thermo-compressors & high-vacuum system suggests that the recompression feature of Evaporators-thermal recompression conserves the energy during the process.

          Here at alaquainc we are equipped with highly skilled engineers and technicians, who are efficient in producing the evaporators-thermal recompression machines and other equipment to serve our domestic and international base of customers. We have highly trained professionals with tremendous experience at your service.

We train your operators to avoid any complications, any help you in the desired manner so that you can achieve the most worthwhile solutions. That results in accomplishment of your targets and growth in your profit.

However, entrepreneurs involved in industries like food processing, pharmaceuticals, waste management, oil refining and many others are making efforts so that they can make their business more cost-effective by reducing the cost of fuel and improving the quality of the product.

If evaporators-thermal recompression can be installed into the new and existing systems then many number of plants could be easily converted to the evaporators those have the multiple abilities which would be beneficial for our customers and their businesses. By taking this step, one can reduce the costs over production. It could be proved a more practical method in comparison with others. The use of evaporators-thermal recompression could make a difference as it would help our customers in making their business more successful.

Adequateness of evaporators-thermal recompression

       More than one-third of the steam and water can be saved by the use of evaporators thermal recompression in which is unachievable in evaporator system with non-usage of thermo-compressors. In this way things become more efficient and profitable.

The latest technologies used in Evaporators & Crystallizers

Due To The Technological Advancements In The Field Of Crystallization And Evaporation, It Will Become More Important To Select The Appropriate Industry That Provides You The Best Possible Outcome. We Take The Responsibility To Give You The Latest Technological Equipment. We Mostly Deal In Evaporators, Crystallizers, Solvent Recovery System, Heat Exchangers, Distillation Equipments And Spray Dryers. Nowadays No one Uses the Non-Integrated Design and Manufacturing Methods, We Are The Best In Providing You The Fully Integrated Designs As Well Manufacturing Processes.

Good Evaporator Should Fulfill Certain Criteria Like

 1) Coil Temperature Should Be Correct For This We Have The Qualified Design Engineers Who Are Responsible To Maintain The Correct Pressure All The Time.

2)All The Liquid Should Be Boil To A Vapour For This We Have The Qualified Technician Who Gives The Surety That All the Liquid Is Converted To Vapour Because A Compressor Cant Work With A Liquid.
