Multicyclones and cyclonettes
Los multiciclones y las «cyclonettes» de Alfa Laval se utilizan para el lavado, la concentración, la clarificación y la clasificación del almidón. Sea cual sea el reto al que se enfrente con su suspensión de almidón, puede confiar en nuestros sistemas de multiciclones para aumentar la capacidad, mejorar la calidad del producto o recuperar el almidón de los efluentes del proceso, al tiempo que se reducen los costes de mantenimiento. Son perfectos para su uso con suspensiones de almidón
La separación rápida y precisa del almidón aumenta el rendimiento del producto
- Máxima eficacia de lavado y bajo consumo de agua
- Fácil de manejar, larga vida útil
- Control automático opcional
- Bajos costes de mantenimiento, ya que no hay piezas móviles
- Fácilmente ampliable para aumentar la capacidad
Para una producción satisfactoria de almidón es necesario aprovechar al máximo las materias primas y conseguir la calidad deseada en el producto final mediante un procesamiento seguro, rentable y sostenible. Confíe en los multiciclones y las ciclonetas de Alfa Laval para obtener una separación centrífuga versátil y altamente eficiente, tanto para el lavado del almidón como para la concentración, clarificación o clasificación de las suspensiones de almidón.
La diferencia de tamaño y densidad entre el almidón y las impurezas, como el gluten y la fibra fina, permite utilizar la separación centrífuga con ciclones para las aplicaciones mencionadas anteriormente. Los sistemas se pueden configurar fácilmente para adaptarse a sus necesidades específicas, y es posible aumentar o reducir la capacidad sin dificultad siempre que sea necesario.

How does the multistage starch washing system work
The multistage starch washing system comprises several multicyclones installed in series. In front of each stage is a centrifugal feed pump.The starch milk enters the first washing stage. It is washed in a counter-current stream of water and leaves at the underflow of the last stage as concentrated purified starch milk.
The underflow of a given washing stage contains the concentrated starch milk and the overflow entrains the impurities and some recycled starch. The underflow of a given stage is together with the overflow of the second to next stage transferred to the feed pump of the intermediate stage. In this way, the starch milk entering the system in the first stage is washed by dilution and concentration in the subsequent stages and leaves the system via the underflow of the last stage.
The wash water entering the system ahead of the last washing stage leaves the system via the overflow of the first washing stage carrying the impurities such as soluble protein, gluten and fine fibre out of the system. The first stage overflow also contains a certain amount of starch that is recycled to the upstream process.
Types of multicyclones for starch processing
- RH multicyclones with a large capacity radial matrix design
- PH multicyclones with a small to mid-range capacity design and parallel manifolded cyclonettes
The RH multicyclones are primarily used for starch washing in large capacity corn wet milling plants with grind rates above 900 ton/day corn. The PH multicyclones are used in all other applications.
The Alfa Laval cyclonettes are installed inside the multicyclone housing. Separation takes place when the feed pressure is converted to a rotation of the liquid as it enters the cyclonette. This generates the required g-force inside the cyclonette for fast and accurate particle separation.
Several types of cyclonettes are available:
- 10 mm PC10 cyclonettes for washing, concentration and clarification of starch suspensions from corn, wheat and tapioca in PH type multicyclones.
PC10 cyclonettes can also be installed in the old Dorr-Oliver TM multicyclones. - 15 mm PC15 cyclonettes for washing, concentration and clarification of starch suspensions from potato in PH type multicyclones.
PC15 cyclonettes can also be installed in the old Dorr-Oliver TM multicyclones. - 10 mm RC10 cyclonettes used mainly for washing corn starch suspensions in the RH type multicyclones.
RC10 cyclonettes can also be installed in the old Dorr-Oliver radial matrix multicyclones. - 10 mm cyclonettes for the old Dorr-Oliver Clamshell multicyclones.
- 10 mm and 15 mm MOCL cyclonettes for the old Alfa Laval MOCL multicyclones.
