Reciprocating Action Solves Tough Heat Exchange Challenges

Scraped floor heat exchangers have been used for tough heat switch functions involving viscous fluids or the place fouling is an issue, such as 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 relies on this strategy. However, เกจวัดแรงดันปั๊มลม is not optimal for every scenario, and so HRS developed the Unicus Series of reciprocating scraped floor heat exchangers.
The Unicus Series of reciprocating scraped surface warmth exchangers is right for viscous merchandise similar to cream and tomato juice, as nicely as merchandise containing fruit items or particles.
The HRS Unicus Series is particularly designed to supply the improved heat transfer of a traditional SSHE, however with a gentle motion to protect the quality and integrity of delicate meals merchandise similar to cheese, yoghurt, ice cream, meat paste, and merchandise containing entire pieces of fruits or vegetables. Over the years, a variety of different scraper designs have been developed, meaning that every application, from processing curds to heating sauce or pasteurizing fruit compotes can be dealt with in probably the most environment friendly but light method possible. Other applications the place the Unicus Series has been useful include 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 preserving the tube wall clean and in addition creates turbulence within the materials. Together, these actions enhance the speed of warmth transfer within the materials, making a highly efficient course of that is best for viscous and excessive fouling supplies.
Since they are controlled separately, the pace of the scrapers could be optimized for a specific product being processed, in order that supplies that are susceptible to shear stress or strain damage (such as lotions and custards) can be dealt with delicately to stop harm whereas still offering excessive ranges of heat switch. The Unicus Series has confirmed significantly helpful in handling viscous food products where texture and consistency are necessary attributes. For instance, some creams or sauces might shear when subjected to excess stress, making them unusable. The Unicus signifies that efficient warmth transfer could 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 items a pneumatic cylinder can be equipped instead), a separation chamber to ensure hygiene and preserve product separation from the motor, and the warmth exchanger itself. The heat exchanger consists of a number of tubes, each of which accommodates a stainless-steel rod to which the suitable scraping elements are fitted. Using a range of food-safe materials together with Teflon and PEEK (polyether ether ketone), these present different internal geometry setups in accordance with the application, corresponding to 120-degree scrapers for large particulates and 360-degree scrapers for viscous fluids without particulates.
The Unicus Series is also fully scalable by growing the shell diameter and including extra interior tubes from a single tube as much as eighty in one shell. A key function is the specially designed seals which separate the inside tube from the separation chamber, tailor-made to the product utility. These seals stop leakage of the product and ensure inside and exterior hygiene. A standard range of fashions for meals processing present heat transfer areas from 7 to 107 sq. toes, while larger models as much as practically 1,300 square toes can be made for specific uses.
One area where the Unicus Series excels is in evaporation functions, the place the prevention of fouling is especially essential. HRS has a particular model of the Unicus to be used in evaporation items the place quantity reduction of the fabric is crucial. The scraping action retains the heat transfer surfaces clear in order that Unicus evaporators can concentrate supplies to a degree that’s unattainable using conventional technologies. Unicus evaporators can be used in multi-effect setups or in combination with mechanical vapor recompression.
