CLARA - CLARA 500 - Medium-capacity solids-ejecting centrifuge for the wine and beverage industries - 1

Medium-capacity solids-ejecting centrifuge for the wine and beverage industries CLARA 500 Alfa Laval disc stack centrifuges for the wine and beverage industries are available in many different sizes and confi gurations, each specially designed for a specifi c kind of separation duty. With a feed fl ow capacity of up to 50 m3/h*, combined with excellent solids handling capability, the CLARA 500 is ideal for conditions common in many of the processes used in the wine and beverage industries. The CLARA 500 design combines the benefi ts of a high G-force, a high standard of hygiene and automated operation. The Alfa Laval CLARA 500 clarifi er features the computerized Alfa Laval SmartEject self-triggering system, which provides intermittent discharge of solids that have a high dry matter content. The CLARA 500 is also equipped with Oxy-Stop, a hydrohermetic seal that ensures minimal oxygen pick-up in the clarifi ed liquid. * actual capacity depends on the specifi c application Applications The Alfa Laval CLARA 500 is specially designed for use in the wine and beverage industries, and is particularly suitable for clarifying the following products: • white grape must (free run and press juice) • young wine (still and sparkling) • matured wine • fruit juices (deciduous, citrus and tropical). The CLARA 500 can be used for removing suspended solids that contain particles in the size range 0.5–500 ìm. The solids content in the feed is normally in the range of 0.1–10% by volume, depending on the specifi c operation involved, but can also be higher. Standard design The machine consists of a frame that has a horizontal drive shaft, worm gear, lubricating oil bath and vertical bowl spindle in the lower part. The motor is of a type suitable for variable frequency drive (VFD). The bowl is mounted on top of the spindle, inside the space formed by the upper part of the frame, the solids collecting cover, and the frame hood. The feed and liquid discharge CLARA 500 complete with motor system also rests on this structure. All metallic parts that come in contact with the process liquid are made of highgrade stainless steel. Liquid-wetted rubber gaskets are made of FDA-compliant nitrile rubber. The upper part of the frame and the hood are cooled with water, which reduces temperature increase of the process medium to a minimum and acts as a sound dampener at the same time. The CLARA 500 centrifuge is equipped with sensors for monitoring bowl speed and vibration level. Flushing takes place inside, above and under the bowl, in the solids collecting ring, and in the Oxy-Stop seal.

Special features The discharge volume in the CLARA 500 is adjustable. Combined with the SmartEject self-triggering system, this ensures discharge of solids that have a high dry matter content, which minimizes product losses. The CLARA 500 is also equipped with Oxy-Stop, a hydrohermetic seal that ensures minimal oxygen pick-up. The centrifuge is equipped with a built-in paring disc for the separated product, eliminating the need for an external pump. The top part of the frame and the frame hood are jacketed for cooling and sound dampening. The sliding bowl bottom is fitted with an easily...
