Scraped floor heat exchangers have been used for tough warmth switch applications involving viscous fluids or where fouling is a matter, corresponding to evaporation processes. The commonest sort of scraped surface warmth exchanger (SSHE) makes use of a rotating shaft with blades or augers which scrape the surface of the tube. The popular HRS R Series is based on this method. However, the design isn’t optimum for each scenario, and so HRS developed the Unicus Series of reciprocating scraped surface warmth exchangers.
The Unicus Series of reciprocating scraped floor warmth exchangers is ideal for viscous merchandise such as cream and tomato juice, in addition to products containing fruit pieces or particles.
IT STARTS WITH DESIGN
The HRS Unicus Series is particularly designed to supply the improved warmth switch of a conventional SSHE, but with a delicate motion to protect the quality and integrity of delicate meals products corresponding to cheese, yoghurt, ice cream, meat paste, and products containing whole items of fruits or greens. Over the years, a selection of totally different scraper designs have been developed, meaning that each application, from processing curds to heating sauce or pasteurizing fruit compotes can be handled in essentially the most efficient yet light way potential. Other functions where the Unicus Series has been beneficial embrace dealing with meat slurry and mince, and processing yeast-malt extracts.
The hygienic design uses a patented stainless-steel scraping mechanism that strikes hydraulically forwards and backwards inside each inside tube. The movement performs two key functions: it minimizes potential fouling by keeping the tube wall clear and likewise creates turbulence inside the material. Together, these actions improve the rate of warmth switch within the material, creating a highly efficient process that is best for viscous and excessive fouling materials.
Since they’re controlled individually, the pace of the scrapers may be optimized for a particular product being processed, so that supplies that are prone to shear stress or stress injury (such as creams and custards) may be dealt with delicately to prevent injury whereas nonetheless providing high ranges of warmth switch. The Unicus Series has proven notably helpful in handling viscous meals products the place texture and consistency are important attributes. For instance, some creams or sauces could shear when subjected to extra strain, making them unusable. The Unicus implies that efficient warmth switch may be carried out at low pressures which overcomes these problems.
HRS UNICUS SERIES UP CLOSE
Each Unicus SSHE consists of three elements: a hydraulic cylinder and power pack (although in smaller items a pneumatic cylinder could be supplied instead), a separation chamber to ensure hygiene and preserve product separation from the motor, and the heat exchanger itself. The warmth exchanger consists of a quantity of tubes, every of which accommodates a stainless-steel rod to which the appropriate scraping elements are fitted. Using a range of food-safe materials including Teflon and PEEK (polyether ether ketone), these provide completely different inner geometry setups according to the appliance, such as 120-degree scrapers for giant particulates and 360-degree scrapers for viscous fluids without particulates.
The Unicus Series can also be totally scalable by growing the shell diameter and including more interior tubes from a single tube up to eighty in a single shell. A key feature is the specifically designed seals which separate the internal tube from the separation chamber, tailor-made to the product application. These seals prevent leakage of the product and guarantee inside and external hygiene. A normal vary of models for meals processing provide warmth switch areas from 7 to 107 sq. ft, whereas larger models up to nearly 1,300 square feet could be made for particular uses.
EXCELLENCE IN ACTION
One space where the Unicus Series excels is in evaporation applications, where the prevention of fouling is particularly essential. HRS has a particular model of the Unicus for use in evaporation items where volume discount of the fabric is important. digital pressure gauge ราคา scraping motion keeps the heat switch surfaces clean in order that Unicus evaporators can concentrate supplies to a stage that is unattainable utilizing conventional technologies. Unicus evaporators can be used in multi-effect setups or together with mechanical vapor recompression.
