摘　　要：介绍了一种结合液氮喷淋和流态化速冻各自特点的液氮喷雾流态化速冻机,它以液氮为冷源,替代庞大复杂的制冷系统,实现了单体快速冻结,减少了初投资,提高了食品冻结质量。A new type of Liquid Nitrogen(LN_2)-Spraying fluidified quick freezer was introduced. The quick freezers were developed based on the LN_2-Spraying system and fluidify system, thus quick-freezing and decreased initial investment can be realized. The quality of the food was also improved.
