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.

Services that we provide:

·         Engineering, fabrication, installation, start-up and personnel training are provided by us on every application. Instantaneous response is provided on every troubleshooting call.

·         Engineering and consulting services are also among our list of services.

·         Operation to specifications are always guaranteed.

·         We are always at your service, 24 hours a day despite of your location.

Including this we provide basic and detail engineering services, fabrication of equipment, retro fitting services, field services, troubleshooting services, installing and commissioning services along with training the personnel.
Basic engineering services include three major drawings:
·         Process flow drawing.

·         P&I drawing.

·         General arrangement drawing with loads.

Amplitudes for all the vessels, pumps and pipe work for the system would be measured by alaquainc, not only this but also be designed by the same, so that the unit functions correctly. Once installed by the customer, we assist the customer in operating the unit systematically.

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.

How Falling Film Evaporators Are Rendered Tasks At Distillery Stillage Industrial Unit?


Before filling inside knowledge about film evaporators, let’s intellect what is evaporator? An evaporator means the equipment which is employed under vacuum in order to let the water evaporate present in the solution through the inlet feed point. Evaporators have got their exercise in food, dairy, chemical, or other industries. In the plant of the distillery, decreasing the volume of liquid effluents and recovering the water is essential for generating the final product. Falling film evaporators is one of the sorts, pushed in exploitation for distillery stillage. This evaporator is put in use for purposes like bio methanation spent wash and RO reject water concentration.

How does the cycle within falling film evaporators conduct?  

    Product
    Concentrate
    Condensate
    Vapor
    Deaeration
    Steam
    Falling Film Calandria
    Vapor Separator

What is the working direction of falling film evaporators?

In such evaporators, the liquid product makes its entry from the head and is equally distributed into the heating tubes placed inboard. A thin film then gets in the heating tubes of falling film evaporators and flows down at boiling temperature & is evaporated to a partial extent. To heat the evaporator, steam is usually used. Further, product and vapor flow downward, maintaining the parallel format. That the downward movement is hereafter augmented by the current of flowing vapor. When the concentrated product separates, a vapor is formed and undergo the bottom section of the separator and heat exchanger devices assembled with the falling film evaporators.

How much in numbers are the limitations of the falling film evaporators?

·        If great precautions and monitoring is put into action, 30% concentration might be accomplished.
·        The smell of fowl causes pollution in the atmosphere as well as bed environment.
·        High foaming and entrainment are the limits for obtaining the effective capacity of such an evaporator.
·        Scale formation in the evaporator can be cleaned after 8 to 10 days by making the selection of the correct combination of MEE with efficient feed treatment methods.
·        Extra effluent generation occurs because of chemical cleaning and special treatment prior to discharging to the main ETP set up.
·        It could seem highly risky to live when bio digester overflow and falling film evaporator is approached as an Integrated Evaporation Arrangement.
·         
Does remedial measures can be adopted in the case of falling film evaporators?

·        Auto feed control and monitoring system can be installed for the process supervision.
·        Auto steam/temperature control can be made a component of the evaporation frame.
·        Operating cooling water temperature monitoring system for the correct observance.
·        Deploying the Stand by Calandria with extra valves.
·        For the factor to avoid scale formation, pretreatment is an important step.

Is there any problem materialize in bio methanation spent wash plying falling film evaporators?

·        Excessive foaming concludes at polluted condensate.

Solution:

A new design gas removing system can be brought into play which involves rotary clarifier, DSI, gas separator Calandra, anti-foaming mechanism, compressed air injection with filter cartridge for micronizing the air to eliminate the solids that are in suspended stage & also induced draft type gas removal unit with fines ( SS ) removal and sludge scraper.
