| 165094000 | WITH SCRAPER REMOVING PRODUCT FROM TEMPERATURE MODIFYING SURFACE | 7 |
| 20080202728 | Device for Reducing Fouling in a Tubular Heat Exchanger - The invention relates to a device for reducing fouling in a tube ( | 08-28-2008 |
| 20090188648 | Heat Exchanger - A heat exchanger comprises a plurality of heat exchange tubes inserted into a cleaning device. The cleaning device has the effect of movably scraping the dirt or dust accumulated in an outer side of each heat exchange tube, and a watering device is provided for spraying water to lower the temperature of the heat exchange tubes and to clean the heat exchange tubes. The cleaning device cooperates with the watering device to scrap the dirt or dust accumulated in the heat exchange tubes, clean and lower the temperature of the heat exchange tubes, so as to prevent the dirt or dust from being accumulated in the heat exchange tubes, improve the radiating effect of the heat exchange tubes and save the energy. | 07-30-2009 |
| 20130306270 | SCRAPING HEAT EXCHANGER - The invention relates to improvements of a scraping heat exchanger having an outer cylinder comprising a first wall having a smooth circle-cylindrical inner side, and an inner cylinder positioned concentrically within it. The improvements regard a simple detachable inner cylinder, a heat exchanger with lid including a fluid barrier, a heat exchanger with a tangential output, and a method and heat exchanger adapted for improved evacuation of a product chamber of a heat exchanger. | 11-21-2013 |
| 20140209274 | SELF-PUMPING HEAT EXCHANGE UNIT - In addition to efficiently removing residues from the inner wall of the inner tubes ( | 07-31-2014 |
| 20150083366 | MULTI-SURFACE HEAT EXCHANGE WITH VACUUM CAPABILITY AND MAGNETIC SCRAPERS - A multi-surface scraped surface heat exchanger for heating or cooling of liquids or slurries having a series of three or more concentric tubes that provide four or more heat transfer surfaces, three of which are independently temperature and flow controllable. Slurry products are cooled or heated across all of the surfaces in line or in parallel. Scrapers are mounted on a rotor assembly and are magnetically or spring tensioned to increase surface engagement and may be contoured to enhance folding and mixing of product. | 03-26-2015 |
| 20160018170 | SCRAPE-OFF TYPE HEAT EXCHANGER - Provided is an inexpensive scrape-off type heat exchanger that is simple in construction, eliminating the need for using a pump for forcibly feeding the process fluid. With the scrape-off type heat exchanger ( | 01-21-2016 |
| 20160161168 | HEAT EXCHANGER FOR USE IN COOLING LIQUIDS - A heat exchanger has at least one inlet and outlet to permit circulation of refrigerant therethrough. Each heat exchanger includes a plurality of thin sections of material arranged between a pair of thin flat outer plates. Each of the thin sections of material is comprised of parallel flow paths, allowing for the refrigerant to flow through the inlet, then from one section to the next, and finally out the outlet. The arrangement of the sections of parallel flow paths allows for the refrigerant to come into contact with the majority of the inside wall of the outer plates, allowing for maximum heat exchange. In use for cooling liquids, the heat exchangers are arranged within a frame and brought into contact with the liquid to be cooled. When the heat exchangers are used to cool liquid sufficiently to produce ice crystals, a rotating scraping device sweeps across the surface of the heat exchanger, removing any ice crystals that have formed. | 06-09-2016 |
