About – Alaqua Inc.
Alaqua Inc. is the supplier of processing equipment across the globe since 1989. We supply evaporators, crystallizers, and distillation systems and we have proven ourselves time and again to provide the most trusted products. Here we will talk about the types of evaporators made in USA by Alaqua Inc. to be supplied across the Globe.
An evaporator system is a machine that is used for chemical processing for different purposes in industries. These evaporators services also come in different varieties as per the purpose required. The evaporators are used for the liquid chemicals and components to convert the liquid to vapor.
We are an evaporators supplier from USA. We supply different types of evaporators across the Globe for different purposes that are mentioned below:
Falling Film Evaporator
Falling Film Evaporators are used as the heat exchanger from a liquid through vaporization. It is an evaporator where the liquid products enter from the top where the product is evenly distributed in the heating tube after which a thin film enters the heating tube and flows downwards at boiling temperature and evaporates. Falling Film Evaporators are majorly used for the dairy products such as milk protein, whey, cream, etc., sugar solutions, phosphoric acid, black liquor, and urea.
Forced Circulation Evaporator
Forced Circulation Evaporators are used if the feed contains solids or crystals and is used for both heat exchanger and flash separator. It consists of a vertical shell and heat exchanger tube along with a centrifugal pump. The additional advantages with these type of evaporators are that it has a high transfer efficiency, positive circulation, and reduced fouling. Forced Circulation Evaporators are majorly used for sodium sulfate, sodium chloride, urea, ammonium sulfate, citric acid, magnesium chloride, and caustic potash.
LTV or Long Tube Vertical Evaporators is also known as the rising film evaporators and are a combination of rising and falling film evaporators. These operate on the “thermo-siphon” principle where a very high ratio of evaporation is necessary to feed and the bundle of tubes can be divided or separated into two parts where the first one to operate is a rising-film and the second part as a falling-film. The LTV Evaporators can be used for the concentration of sugarcane syrups, nitrates, black liquor in paper plants, and electrolytic tinning liquors.
Plate evaporator is also known as gasketed plate and frame evaporator is a method in which a thin film is passed between the plates to conduct the evaporation. These evaporators contain a plate and frame heat exchanger and are majorly used by the foods and beverages industry. The major advantages of these evaporators are low headroom is required, it can be modified and cleaned easily and adapted to materials as well. These evaporator systems are used for fruit juices, fruit puree, syrup, milk, coffee.
Mechanical Vapor Recompression (MVR)
The heat of condensation of the working fluid is revived by increasing the temperature and pressure of the fluid and then condensing it. MVR has higher CAPEX (Capital Expenditure) and lower OPEX (Operating Expenses) that makes it attractive. Several features that make MVR unique from others are that the preheaters give short residence time to the external preheaters, better deaeration of the calandrias along with easy inspection and cleaning.
Thermal Vapor Recompression (TVR)
TVR or Thermal Vapor Recompression is widely used in the process industry to revive low-grade waste heat from an active fluid majorly steam. It uses the thermocompressor to decrease the steam necessary per pound of evaporation. The TVR is used to reduce energy consumption where water vapor from an evaporator is divided and compressed with high-pressure steam so it can be condensed in the evaporator heat exchanger. A thermocompressor is quite similar to a steam-jet air ejector that is used to maintain a vacuum in an evaporator.
Compact Skid Mounted Evaporator
We at Alaqua Inc. have a wide variety of multi-purpose compact evaporators that makes it the most suitable to be chosen for dairy, beverage, specialty food, and industrial fluid applications. This evaporator is designed to be functionally identical to the time-tested and is largely accepted long-tube falling film evaporators that are majorly used for food, pharmaceutical, and many industrial applications.
