LOW-TEMPERATURE-SLUSH-FLUID PRODUCING APPARATUS

摘要

A low-temperature-slush-fluid producing apparatus capable of achieving an increased weight solidification rate of slush fluid is provided. A low-temperature-slush-fluid producing apparatus includes a slush-fluid producing unit that includes a heat exchanger having a heat-transfer surface and disposed in a liquid-phase low-temperature fluid L stored in a container and scraping means for scraping a solid-phase low-temperature fluid formed on a surface of the heat-transfer surface; and a cryogenic-fluid generating unit for supplying into the interior of the heat-transfer surface a cryogenic fluid having a lower temperature than the liquid-phase low-temperature fluid L stored in the container. The low-temperature-slush-fluid producing apparatus is configured so that the flow rate and temperature of the cryogenic fluid flowing into the interior of the heat-transfer surface and the rotational speed or reciprocating speed of the scraping means can be adjusted based on the particle size of the solid-phase low-temperature fluid scraped by the scraping means.
