Quality Leap, Reshaping the Standard for High-End Seafood Snacks: The low-temperature vacuum process completely solves the traditional frying problems of "greasiness, scorching and nutrient loss." The crispness of the finished yellow croaker crisp is increased by more than 30% and the oil content is reduced by 25%, perfectly meeting the demand of high-end markets in Europe, America and China for "clean labels" and "low-fat health," helping Xianghai Foods further consolidate its position as an industry benchmark.
Zhejiang Xianghai Foods Co., Ltd. is located in Zhoushan, Zhejiang, the core production region of aquatic products, and is a leading enterprise in China's marine leisure food industry. The company has been deeply engaged in the deep processing of small yellow croaker and crispy seafood snacks for many years, and has a standardized 100,000-class purified production workshop and a large-scale cold-chain warehousing system. Its flagship best-selling product, "Yellow Croaker Crisp," sells well across the country, with supply channels covering major supermarkets, snack chains, e-commerce platforms and OEM systems; it is a benchmark factory for low-temperature vacuum frying of aquatic products in East China.
Pain points of the aquatic yellow croaker crisp processing industry
Tender flesh, easily damaged by high-temperature frying: The small yellow croaker has tender flesh and fine bones, and traditional atmospheric high-temperature frying easily causes skin breakage and flesh loss, resulting in incomplete products; moreover, high temperatures destroy the fresh aroma of the fish, and the bones are difficult to fry until crisp, failing to meet the standard of a best-selling product.
High oil consumption, and the finished product is prone to oxidation and rancidity: Conventional equipment has poor de-oiling performance, and the yellow croaker crisp has a relatively high oil content; during storage it easily becomes oily, greasy and oxidized with off-flavors, resulting in a short shelf life and requiring additional antioxidant ingredients and cost.
Insufficient capacity for large-batch centralized production: The fishing and processing cycle of yellow croaker is concentrated, small equipment has limited single-batch capacity, and piled-up raw materials are prone to spoilage, unable to meet the continuous supply needs of large national orders.
Cumbersome cleaning of aquatic processing, difficult to meet hygiene standards: Aquatic processing involves heavy oil stains and much fish-scale residue; ordinary equipment has many dead corners, cleaning takes a long time, and frequent shutdowns for cleaning seriously affect all-day continuous production efficiency.
Our customized solution of 8 sets of 300kg vacuum low-temperature fryers
Eight 300kg batch vacuum frying units are configured for Xianghai Foods, specially optimized for small yellow croaker aquatic raw materials and suitable for the large-scale mass production of yellow croaker crisp:
Vacuum low-temperature negative-pressure freshness-locking process: The whole process performs dehydration and frying in a low-temperature vacuum environment, processing the small yellow croaker gently to ensure the flesh remains intact and does not break up, and the bones are fully puffed and crispy and directly edible; the low temperature isolates air oxidation, fully preserving the natural umami of the fish, with a uniform golden color and stable appearance.
High-efficiency centrifugal automatic de-oiling system: The equipment has a built-in high-speed centrifugal de-oiling structure, greatly reducing the oil content of the finished product, making the yellow croaker crisp refreshing and not greasy, delaying oil oxidation, extending the product shelf life and reducing the use of preservative additives.
Automatic oil-water circulation filtration for long-term cost reduction: Equipped with a continuous oil filtration circulation device that filters impurities such as fish scales and flesh residue in real time, slowing the blackening and deterioration of frying oil and effectively extending the oil replacement cycle; long-term large-batch production can significantly save oil costs.
Food-grade whole machine, easy to clean and continuous production: The whole machine is made of 304 stainless steel food-grade material, with no dirt-hiding dead corners and support for quick flushing and cleaning, suitable for the production environment with heavy oil stains in aquatic processing; three units are arranged in parallel, supporting 24-hour uninterrupted continuous production.
Intelligent integrated control system: Independently preset frying process parameters dedicated to aquatic products; vacuum degree, temperature and frying time can be controlled with one button, parameters are automatically stored, manual operation is simple, ensuring highly consistent taste and crispness of each batch of yellow croaker crisp.
Capacity and product value improvement
Large capacity matches the centralized processing needs of aquatic products: A single unit feeds 300kg per batch, and eight units running simultaneously can quickly handle large quantities of small yellow croaker raw materials, solving the loss from raw material backlog during the fishing season, stably undertaking large orders from supermarkets and e-commerce nationwide, and doubling capacity.
