Reciprocating Action Solves Tough Heat Exchange Challenges

Scraped floor warmth exchangers have been used for tough heat switch applications involving viscous fluids or the place fouling is a matter, corresponding to evaporation processes. The most common kind of scraped floor heat exchanger (SSHE) uses a rotating shaft with blades or augers which scrape the surface of the tube. The in style HRS R Series is based on this approach. However, the design isn’t optimal for every situation, 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 merchandise corresponding to cream and tomato juice, in addition to merchandise containing fruit items or particles.
The HRS Unicus Series is particularly designed to provide the improved heat switch of a standard SSHE, however with a mild action to protect the standard and integrity of delicate food merchandise similar to cheese, yoghurt, ice cream, meat paste, and products containing complete pieces of fruits or greens. Over the years, numerous completely different scraper designs have been developed, which means that each utility, from processing curds to heating sauce or pasteurizing fruit compotes could be dealt with in essentially the most efficient but light way potential. Other purposes where the Unicus Series has been useful embrace dealing with meat slurry and mince, and processing yeast-malt extracts.
The hygienic design uses a patented stainless-steel scraping mechanism that moves hydraulically back and forth within every interior tube. The motion performs two key features: it minimizes potential fouling by keeping the tube wall clear and also creates turbulence within the material. Together, these actions increase the speed of warmth transfer in the materials, creating a extremely efficient course of that’s perfect for viscous and high fouling materials.
Since they’re managed individually, the velocity of the scrapers could be optimized for a specific product being processed, so that supplies that are vulnerable to shear stress or strain injury (such as creams and custards) can be handled delicately to prevent damage while still providing high levels of warmth transfer. The Unicus Series has confirmed particularly helpful in dealing with viscous food products the place texture and consistency are essential attributes. For instance, some lotions or sauces may shear when subjected to excess stress, making them unusable. The Unicus signifies that efficient warmth switch can be carried out at low pressures which overcomes these problems.
Each Unicus SSHE consists of three components: a hydraulic cylinder and energy pack (although in smaller models a pneumatic cylinder can be provided instead), a separation chamber to make sure hygiene and preserve product separation from the motor, and the heat exchanger itself. The heat exchanger consists of a selection of tubes, each of which accommodates a stainless-steel rod to which the appropriate scraping components are fitted. Using a variety of food-safe supplies including Teflon and PEEK (polyether ether ketone), these present completely different inner geometry setups according to the applying, similar to 120-degree scrapers for giant particulates and 360-degree scrapers for viscous fluids with out particulates.
The Unicus Series can be absolutely scalable by rising the shell diameter and adding more interior tubes from a single tube as a lot as eighty in one shell. A key feature is the specifically designed seals which separate the internal tube from the separation chamber, tailored to the product application. These seals forestall leakage of the product and guarantee inner and exterior hygiene. A standard range of models for food processing present heat transfer areas from 7 to 107 sq. toes, while bigger fashions up to nearly 1,300 sq. feet could be made for particular makes use of.
One space where the Unicus Series excels is in evaporation purposes, where the prevention of fouling is especially necessary. HRS has a specific model of the Unicus for use in evaporation units where quantity reduction of the fabric is essential. The scraping action retains the heat switch surfaces clean so that Unicus evaporators can concentrate supplies to a level that is unattainable utilizing conventional applied sciences. Unicus evaporators can be used in multi-effect setups or in combination with mechanical vapor recompression.
