一、划时代的快速冷冻设备日本—食品工业株式会社,1978年发明了一种瞬间结冻库,具有划时代的意义。普通结冻库温约为-25℃,产品因冻结时间长,水分蒸发多,冰结晶大,故品质易于劣化、老化。解冻时品质亦显著降低。为此,曾发明-35—60℃快速冷冻机,但全负荷运行,解冻困难,而且电动机耗量大,又空冷时,不能速冻。用液态氮速冻,只能冻结表面,不能
First, epoch-making rapid freezing equipment Japan - Food Industry Co., Ltd., in 1978 invented a kind of instant freezing reservoir, epoch-making significance. Normal junction freezing temperature is about -25 ℃, the product is frozen for a long time, more water evaporation, crystallization of ice, so the quality is easy to deteriorate, aging. Thaw quality is also significantly reduced. To this end, had invented -35-60 ℃ fast freezer, but full load operation, thawing difficulties, and the motor consumption, and air-cooled, can not be frozen. Frozen with liquid nitrogen, can only freeze the surface, can not
