Roller shutter quick-freezing equipment and quick-freezing method for aquatic products

Abstract

Relating to the field of aquatic product refrigeration, the invention aims to provide roller shutter type aquatic product quick-freezing equipment and a quick-freezing method. The roller shutter type aquatic product quick-freezing equipment comprises: a heat preservation box equipped with a feeding device and a quick-freezing device, and also includes a roller shutter device equipped with an aquatic product carrying steel belt stretching into the heat preservation box, an aquatic product turnover device disposed above the aquatic product carrying steel belt, and an inclined discharge path arranged below the aquatic product carrying steel belt. A lower end of the inclined discharge path extends out of the heat preservation box. The roller shutter type aquatic product quick-freezing equipment provided by the invention enables consistent freezing speed at the upper and lower parts of aquatic products, and the quick-freezing time is short.
