A large coastal aquatic products processing enterprise, specializing in deep processing of seafood such as shrimp, crab and shellfish, previously used traditional quick-freezing equipment, which had problems such as uneven temperature at the center of frozen products, water loss rate up to 15% after thawing, and low production efficiency, seriously affecting product quality and market competitiveness. To solve this pain point, the enterprise selected a customized spiral freezer from Yongxing Factory.
Yongxing’s technical team optimized the wind speed and temperature curve of the quick-freezer according to the characteristics of its seafood products, accurately controlling the quick-freezing temperature at -35℃. The spiral conveying structure maximized space utilization, increasing the single-batch processing capacity to 2.5 times the original. After the equipment was put into operation, the central temperature of frozen products was stably below -18℃, the water loss rate after thawing dropped to 6%, and the fresh and tender taste of seafood was completely retained. At the same time, the intelligent control system equipped with the equipment realized unattended operation and reduced labor costs. At present, the equipment has been operating stably for 3 years, the annual output value of the enterprise has increased by 40% compared with before, and the products have successfully entered the high-end supermarket market.
