Reciprocating Action Solves Tough Heat Exchange Challenges

เกจวัดแรงดันnuovafima have been used for difficult heat transfer purposes involving viscous fluids or where fouling is a matter, corresponding to evaporation processes. The most common kind of scraped surface heat exchanger (SSHE) uses a rotating shaft with blades or augers which scrape the floor of the tube. The popular HRS R Series is predicated on this method. However, the design isn’t optimal for every state of affairs, and so HRS developed the Unicus Series of reciprocating scraped floor warmth exchangers.
The Unicus Series of reciprocating scraped floor warmth exchangers is right for viscous merchandise such as cream and tomato juice, in addition to merchandise containing fruit items or particles.
IT STARTS WITH DESIGN
The HRS Unicus Series is specifically designed to provide the improved heat transfer of a standard SSHE, but with a gentle motion to protect the quality and integrity of delicate food products corresponding to cheese, yoghurt, ice cream, meat paste, and products containing whole pieces of fruits or vegetables. Over the years, a number of completely different scraper designs have been developed, meaning that every application, from processing curds to heating sauce or pasteurizing fruit compotes may be dealt with in the most environment friendly yet light method potential. Other functions the place the Unicus Series has been helpful embrace handling 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 within each inside tube. The motion performs two key capabilities: it minimizes potential fouling by maintaining the tube wall clear and in addition creates turbulence within the material. Together, these actions enhance the rate of warmth switch within the material, making a highly environment friendly course of that’s ideal for viscous and excessive fouling supplies.
Since they are controlled separately, the pace of the scrapers can be optimized for a selected product being processed, in order that supplies which are prone to shear stress or pressure injury (such as lotions and custards) can be handled delicately to prevent damage while still offering excessive ranges of heat transfer. The Unicus Series has confirmed particularly useful in dealing with viscous food products the place texture and consistency are important attributes. For example, some creams or sauces could shear when subjected to excess pressure, making them unusable. The Unicus means that efficient heat switch can 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 models a pneumatic cylinder can be equipped instead), a separation chamber to make sure hygiene and protect product separation from the motor, and the warmth exchanger itself. The warmth exchanger consists of numerous tubes, every of which incorporates a stainless-steel rod to which the suitable scraping components are fitted. Using a spread of food-safe supplies together with Teflon and PEEK (polyether ether ketone), these provide different inside geometry setups according to the appliance, corresponding to 120-degree scrapers for big particulates and 360-degree scrapers for viscous fluids without particulates.
The Unicus Series can also be fully scalable by rising the shell diameter and including more inside tubes from a single tube as much as eighty in a single shell. A key function is the specially designed seals which separate the inner 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 vary of fashions for meals processing present warmth transfer areas from 7 to 107 sq. feet, while larger models up to nearly 1,300 square toes can be made for particular makes use of.
EXCELLENCE IN ACTION
One area where the Unicus Series excels is in evaporation purposes, where the prevention of fouling is especially necessary. HRS has a selected model of the Unicus for use in evaporation units the place volume reduction of the fabric is important. จำหน่ายเกจวัดแรงดัน scraping motion retains the warmth transfer surfaces clear so that Unicus evaporators can focus supplies to a level that’s unattainable utilizing conventional technologies. Unicus evaporators can be used in multi-effect setups or in combination with mechanical vapor recompression.
