Reciprocating Action Solves Tough Heat Exchange Challenges

Scraped floor warmth exchangers have been used for troublesome heat transfer purposes involving viscous fluids or the place fouling is an issue, corresponding to evaporation processes. The most common type of scraped floor heat exchanger (SSHE) makes use of a rotating shaft with blades or augers which scrape the surface of the tube. The well-liked HRS R Series is based on this strategy. However, the design is not optimum for every scenario, and so HRS developed the Unicus Series of reciprocating scraped floor heat exchangers.
The Unicus Series of reciprocating scraped floor warmth exchangers is good for viscous products such as cream and tomato juice, in addition to merchandise containing fruit items or particles.
IT STARTS WITH DESIGN
The HRS Unicus Series is particularly designed to offer the improved warmth switch of a conventional SSHE, however with a delicate action to protect the standard and integrity of delicate meals products corresponding to cheese, yoghurt, ice cream, meat paste, and merchandise containing whole items of fruits or vegetables. Over the years, a selection of different scraper designs have been developed, meaning that each utility, from processing curds to heating sauce or pasteurizing fruit compotes could be dealt with in probably the most environment friendly but light method possible. Other applications the place the Unicus Series has been helpful embody dealing with meat slurry and mince, and processing yeast-malt extracts.
The hygienic design uses a patented stainless-steel scraping mechanism that strikes hydraulically back and forth within each inside tube. The movement performs two key features: it minimizes potential fouling by keeping the tube wall clear and likewise creates turbulence inside the material. Together, these actions enhance the speed of warmth switch within the materials, making a highly environment friendly course of that’s perfect for viscous and excessive fouling supplies.
Since they’re managed separately, the speed of the scrapers could be optimized for a specific product being processed, in order that materials that are susceptible to shear stress or pressure damage (such as lotions and custards) could be handled delicately to stop harm while still offering excessive ranges of heat transfer. The Unicus Series has confirmed notably helpful in handling viscous meals merchandise where texture and consistency are important attributes. For instance, some creams or sauces may shear when subjected to extra pressure, making them unusable. The Unicus means that effective heat transfer may be carried out at low pressures which overcomes these issues.
HRS UNICUS SERIES UP CLOSE
Each Unicus SSHE consists of three elements: a hydraulic cylinder and power pack (although in smaller units a pneumatic cylinder could be provided instead), a separation chamber to ensure hygiene and protect product separation from the motor, and the warmth exchanger itself. The warmth exchanger consists of a selection of tubes, each of which accommodates a stainless-steel rod to which the suitable scraping elements are fitted. Using a spread of food-safe materials including Teflon and PEEK (polyether ether ketone), these provide totally different inside geometry setups according to the applying, corresponding to 120-degree scrapers for giant particulates and 360-degree scrapers for viscous fluids with out particulates.
pressure gauge 4 นิ้ว ราคา is also totally scalable by increasing the shell diameter and including extra inside tubes from a single tube up to eighty in a single shell. A key feature is the specifically designed seals which separate the inner tube from the separation chamber, tailored to the product software. These seals prevent leakage of the product and ensure inside and exterior hygiene. A normal vary of models for meals processing present heat switch areas from 7 to 107 square toes, while bigger fashions as much as almost 1,300 square feet may be made for particular makes use of.
EXCELLENCE IN ACTION
One space where the Unicus Series excels is in evaporation applications, where the prevention of fouling is especially necessary. HRS has a selected version of the Unicus to be used in evaporation models where quantity reduction of the fabric is crucial. The scraping action retains the warmth switch surfaces clear in order that Unicus evaporators can concentrate materials to a degree that is unattainable utilizing traditional technologies. Unicus evaporators can be utilized in multi-effect setups or together with mechanical vapor recompression.
