Reciprocating Action Solves Tough Heat Exchange Challenges

ร้านซ่อมเครื่องวัดความดันomron have been used for tough warmth transfer functions involving viscous fluids or the place fouling is a matter, corresponding to evaporation processes. The most typical type of scraped floor warmth exchanger (SSHE) uses a rotating shaft with blades or augers which scrape the surface of the tube. The in style HRS R Series relies on this method. However, the design isn’t optimum 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 right for viscous products similar to cream and tomato juice, in addition to merchandise containing fruit pieces or particles.
The HRS Unicus Series is specifically designed to provide the improved warmth switch of a traditional SSHE, however with a gentle motion to preserve the standard and integrity of delicate food merchandise such as cheese, yoghurt, ice cream, meat paste, and products containing whole pieces of fruits or vegetables. Over the years, a number of totally different scraper designs have been developed, meaning that every application, from processing curds to heating sauce or pasteurizing fruit compotes could be handled in probably the most environment friendly yet light method potential. Other purposes the place the Unicus Series has been useful 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 every inside tube. The movement performs two key functions: it minimizes potential fouling by maintaining the tube wall clean and likewise creates turbulence throughout the material. Together, these actions enhance the rate of heat transfer within the materials, making a extremely environment friendly course of that is best for viscous and high fouling materials.
Since they are managed individually, the velocity of the scrapers could be optimized for a specific product being processed, in order that materials that are prone to shear stress or strain damage (such as creams and custards) may be dealt with delicately to stop injury while still providing high levels of warmth transfer. The Unicus Series has proven particularly useful in handling viscous meals merchandise where texture and consistency are necessary attributes. For example, some lotions or sauces might shear when subjected to excess stress, making them unusable. The Unicus means that effective warmth transfer can be carried out at low pressures which overcomes these issues.
Each Unicus SSHE consists of three parts: a hydraulic cylinder and energy pack (although in smaller units a pneumatic cylinder can be supplied instead), a separation chamber to make sure hygiene and protect product separation from the motor, and the warmth exchanger itself. The heat exchanger consists of numerous tubes, every of which incorporates a stainless-steel rod to which the appropriate scraping elements are fitted. Using a spread of food-safe supplies together with Teflon and PEEK (polyether ether ketone), these provide completely different inner geometry setups based on the application, similar to 120-degree scrapers for giant particulates and 360-degree scrapers for viscous fluids without particulates.
The Unicus Series can be totally scalable by growing the shell diameter and adding extra interior tubes from a single tube as a lot as eighty in one shell. A key function is the specifically designed seals which separate the inner tube from the separation chamber, tailor-made to the product application. These seals prevent leakage of the product and guarantee inside and external hygiene. A standard vary of fashions for meals processing present heat switch areas from 7 to 107 sq. feet, whereas bigger fashions up to nearly 1,300 sq. toes could be made for specific makes use of.
One area where the Unicus Series excels is in evaporation applications, the place the prevention of fouling is especially essential. HRS has a particular version of the Unicus to be used in evaporation items where volume discount of the material is important. The scraping motion keeps the warmth switch surfaces clear in order that Unicus evaporators can focus materials to a level that’s unattainable using conventional technologies. Unicus evaporators can be utilized in multi-effect setups or together with mechanical vapor recompression.
