Scraped floor warmth exchangers have been used for troublesome warmth switch applications involving viscous fluids or the place fouling is a matter, corresponding to evaporation processes. The most common type of scraped surface heat exchanger (SSHE) makes use of a rotating shaft with blades or augers which scrape the floor of the tube. The well-liked HRS R Series is predicated on this method. However, the design just isn’t optimal for each 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 such as cream and tomato juice, as well as merchandise containing fruit items or particles.
pressure gauge weksler ราคา is specifically designed to provide the improved warmth switch of a conventional SSHE, however with a delicate motion to preserve the standard and integrity of delicate food products corresponding to cheese, yoghurt, ice cream, meat paste, and products containing whole items of fruits or vegetables. Over the years, a quantity of totally different scraper designs have been developed, meaning that each software, from processing curds to heating sauce or pasteurizing fruit compotes can be dealt with in the most environment friendly but mild method attainable. Other functions where the Unicus Series has been beneficial embrace 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 within every inside tube. The motion performs two key features: it minimizes potential fouling by keeping the tube wall clear and in addition creates turbulence inside the material. Together, these actions increase the speed of heat transfer in the material, creating a extremely efficient process that is perfect for viscous and excessive fouling supplies.
Since they’re managed individually, the pace of the scrapers can be optimized for a selected product being processed, in order that materials which are prone to shear stress or pressure injury (such as lotions and custards) could be handled delicately to stop damage while nonetheless offering excessive levels of warmth switch. The Unicus Series has proven notably useful in dealing with viscous food merchandise where texture and consistency are essential attributes. For example, some creams or sauces could shear when subjected to extra pressure, making them unusable. The Unicus means that efficient warmth transfer can be carried out at low pressures which overcomes these issues.
HRS UNICUS SERIES UP CLOSE
Each Unicus SSHE consists of three parts: a hydraulic cylinder and power pack (although in smaller items a pneumatic cylinder may be supplied instead), a separation chamber to ensure hygiene and preserve product separation from the motor, and the warmth exchanger itself. The heat exchanger consists of numerous tubes, every of which accommodates a stainless-steel rod to which the appropriate scraping parts are fitted. Using a range of food-safe supplies together with Teflon and PEEK (polyether ether ketone), these present different internal geometry setups based on the appliance, such as 120-degree scrapers for big particulates and 360-degree scrapers for viscous fluids with out particulates.
The Unicus Series can also be absolutely 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 characteristic is the specifically designed seals which separate the internal tube from the separation chamber, tailored to the product utility. These seals forestall leakage of the product and guarantee inside and external hygiene. A standard range of fashions for meals processing present heat transfer areas from 7 to 107 sq. toes, while larger fashions up to practically 1,300 sq. 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 particularly necessary. HRS has a selected model of the Unicus for use in evaporation units where quantity reduction of the fabric is essential. The scraping action keeps the warmth switch surfaces clear in order that Unicus evaporators can focus materials 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.
