LOW-TEMPERATURE SLUSH FLUID PRODUCTION APPARATUS

摘要

A low-temperature slush fluid production apparatus that attains an increase of weight solidification ratio of slush fluid. There is provided low-temperature slush fluid production apparatus (1) comprising heat exchanger (12) with heat transfer plane (11) disposed in low-temperature fluid (L) of liquid form held within vessel (10); slush fluid production unit (2) equipped with scraping means (13) for scraping off any low-temperature fluid of solid form produced on the surface of the heat transfer plane (11); and extremely low temperature fluid generating unit (3) adapted to supply an extremely low temperature fluid whose temperature is lower than that of the low-temperature fluid (L) of liquid form held within the vessel (10) to the inside of the heat transfer plane (11), wherein not only the flow rate and temperature of the extremely low temperature fluid flowing into the inside of the heat transfer plane (11) but also the rotational speed or reciprocation speed of the scraping means (13) is regulated in accordance with the particle diameter of low-temperature fluid of solid form scraped off by the scraping means (13).
