Reciprocating Action Solves Tough Heat Exchange Challenges

Scraped surface heat exchangers have been used for troublesome warmth transfer purposes involving viscous fluids or where fouling is a matter, similar to evaporation processes. The commonest sort of scraped floor heat exchanger (SSHE) makes use of a rotating shaft with blades or augers which scrape the floor of the tube. pressure gauge 4 นิ้ว is based on this approach. However, the design just isn’t optimal for each scenario, and so HRS developed the Unicus Series of reciprocating scraped surface warmth exchangers.
The Unicus Series of reciprocating scraped floor heat exchangers is right for viscous products similar to cream and tomato juice, in addition to products containing fruit pieces or particles.
IT STARTS WITH DESIGN

The HRS Unicus Series is specifically designed to offer the improved heat transfer of a conventional SSHE, however with a mild motion to preserve the standard and integrity of delicate food products similar to cheese, yoghurt, ice cream, meat paste, and merchandise containing complete items of fruits or greens. Over the years, numerous different scraper designs have been developed, which means that every utility, from processing curds to heating sauce or pasteurizing fruit compotes could be handled in probably the most efficient yet gentle way attainable. Other purposes the place the Unicus Series has been useful include dealing with meat slurry and mince, and processing yeast-malt extracts.
The hygienic design makes use of a patented stainless-steel scraping mechanism that moves hydraulically forwards and backwards within each inside tube. The movement performs two key features: it minimizes potential fouling by keeping the tube wall clear and in addition creates turbulence within the material. Together, these actions enhance the speed of warmth switch in the materials, making a highly environment friendly course of that’s ideal for viscous and excessive fouling supplies.
Since they’re managed individually, the velocity of the scrapers can be optimized for a specific product being processed, in order that materials which are prone to shear stress or pressure injury (such as lotions and custards) could be handled delicately to prevent injury whereas nonetheless providing excessive levels of heat transfer. The Unicus Series has proven significantly helpful in dealing with viscous meals products the place texture and consistency are essential attributes. For example, some lotions or sauces may shear when subjected to excess stress, 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 components: a hydraulic cylinder and power pack (although in smaller units a pneumatic cylinder may be supplied instead), a separation chamber to ensure hygiene and preserve product separation from the motor, and the warmth exchanger itself. The warmth exchanger consists of a selection of tubes, each of which contains a stainless-steel rod to which the appropriate scraping parts are fitted. Using a variety of food-safe materials including Teflon and PEEK (polyether ether ketone), these present totally different inner geometry setups according to the applying, corresponding to 120-degree scrapers for giant particulates and 360-degree scrapers for viscous fluids without particulates.
The Unicus Series is also fully scalable by rising the shell diameter and adding extra interior tubes from a single tube as a lot as eighty in a single shell. A key characteristic is the specifically designed seals which separate the internal tube from the separation chamber, tailored to the product application. These seals stop leakage of the product and guarantee inside and exterior hygiene. A standard range of fashions for food processing provide heat switch areas from 7 to 107 sq. feet, while bigger models up to practically 1,300 square toes can be made for specific uses.
EXCELLENCE IN ACTION

One area where the Unicus Series excels is in evaporation functions, where the prevention of fouling is especially essential. HRS has a selected version of the Unicus for use in evaporation items where volume discount of the material is essential. The scraping action retains the warmth transfer surfaces clear in order that Unicus evaporators can concentrate materials to a degree that is unattainable using conventional technologies. Unicus evaporators can be used in multi-effect setups or in combination with mechanical vapor recompression.
