El evaporador de placas es un dispositivo de evaporación que utiliza principalmente placas de metal como elementos de transferencia de calor.
Este tipo de evaporador suele estar compuesto por una serie de placas metálicas delgadas, con canales o pasajes entre ellas, a través de los cuales fluye el líquido a evaporar. Los evaporadores de placas se utilizan ampliamente en diversos campos industriales, como la fabricación de azúcar, jugos de frutas, productos lácteos, sopa de huesos, fermentación, etc., debido a su alta eficiencia de transferencia de calor, estructura compacta, fácil expansión, limpieza y mantenimiento sencillos. Pueden evaporar líquidos eficientemente a bajas temperaturas, lograr la separación y concentración de mezclas líquidas, y también presentan ventajas como el ahorro de energía y un fácil control de automatización. Además, las placas de los evaporadores de placas suelen estar diseñadas con ranuras corrugadas para mejorar la turbulencia y la eficiencia de la transferencia de calor. El sellado entre las placas generalmente se logra mediante el uso de juntas de sellado en los bordes para asegurar un paso suave del canal de flujo del medio.
Los metales más comunes utilizados en evaporadores de placas son el acero inoxidable, el titanio y las aleaciones de níquel, seleccionados por su resistencia a la corrosión y durabilidad. Están dispuestos de forma que crean una serie de canales paralelos. Su diseño aprovecha la gran superficie de las placas delgadas para maximizar la transferencia de calor de un fluido caliente a uno frío.
Su diseño proporciona una mayor eficiencia térmica que los evaporadores tubulares tradicionales, lo que reduce considerablemente la necesidad de un área de transferencia de calor. Los evaporadores de placas son rentables, especialmente cuando se requieren materiales metálicos especiales.
Plate Evaporator is purpose built for evaporation, featuring two compact inlet feed connections and a spacious outlet dedicated to vapor and concentrate. It is equipment with one sizable inlet and two smaller outlets for condensate. The design of Plate Evaporator incorporates plates welded in pairs, allowing for effective condensation of heating steam in the welded channel, while the evaporated product smoothly flows through the gasketed channels.
During operation, the hot fluid flows through the wider channels from the bottom of the evaporator plates, while the liquid being evaporated flows through the narrow channels. Heat is transferred from the hot fluid to the liquid through the evaporator plates, causing the liquid to evaporate and the hot fluid to cool down.
It is commonly used in the food, beverage, and pharmaceutical industries for applications such as concentrating juices, syrups, and other liquids. They are also used in chemical and petrochemical plants for various evaporation and concentration processes.
Plate evaporator is an evaporation device that mainly uses metal plates as heat transfer elements.
This type of evaporator is usually composed of a series of thin metal plates, with channels or passages between them, through which the liquid to be evaporated flows.. Plate evaporators are widely used in various industrial fields, such as sugar making, fruit juice, dairy products, bone soup, fermentation, etc., due to their high heat transfer efficiency, compact structure, easy expansion, easy cleaning and maintenance. They can efficiently evaporate liquids at low temperatures, achieve separation and concentration of liquid mixtures, and also have advantages such as energy conservation and easy automation control.
In addition, the plates of plate evaporators are usually designed with corrugated grooves to enhance turbulence and improve heat transfer efficiency. The sealing between plates is usually achieved by using sealing gaskets at the edges to ensure smooth passage of the medium flow channel.
Efficient heat transfer - Arranged in a way that maximizes heat transfer and minimizes temperature difference between two fluids, resulting in a more efficient evaporation process.
Flexible capacity expansion - One prominent advantage of plate evaporator is its capability to increase or decrease capacity by adding or removing plates within the existing framework. This feature stands in stark contrast to shell & tube evaporators, where capacity remains fixed upon installation.
Energy Efficient - Plate evaporators are designed to minimize heat loss, which makes them more energy efficient than other types of evaporators.
Saving - The remarkable heat transfer efficiency translates into a substantial reduction in required heat transfer surface area compared to shell & tube evaporators. Consequently, plate evaporator becomes highly cost-effective, especially when dealing with demanding materials like SMO, titanium, nickel and Hastelloy.
Additionally, the compact and adaptable design of plate evaporator greatly diminish- es expende related to transportion, assembly, and installation when compared to shell & tube evaporators.
Multiple models provide the best choice - In OUDUN, we have multiple models that are suitable for various working conditions selection.
