Title:
LOW-TEMPERATURE SLUSH FLUID PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/145029
Kind Code:
A1
Abstract:
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).
