Hydraulic Contact Fresh-Locking, Energy-Efficient Quick Freezing | New-Generation Hydraulic Plate Freezer Empowers Processing Upgrade for Aquatic Products and Prepared Dishes.

Recently, focusing on the upgrading of food cold chain equipment, the new-generation hydraulic plate freezer has been officially launched to the market. Adopting the hydraulic compression contact quick-freezing principle, the equipment features uniform freezing, low dehydration loss, controllable energy consumption and compact structure. It is suitable for the industrial quick-freezing of block-shaped raw materials including aquatic products, poultry meat and prepared food, delivering low-loss, high-quality fresh-locking solutions for food processors and helping the quick-freezing industry improve quality, efficiency and revenue while cutting costs.

In food quick-freezing processing, conventional blast freezing commonly suffers from high dehydration loss, uneven freezing and juice loss of raw materials, which directly affect the finished product yield and market selling price. This hydraulic plate freezer adopts a hydraulically driven compression structure. With adjustable pressure, it enables tight contact between food and high-thermal-conductivity aluminum alloy freezing plates to eliminate air insulation gaps. It achieves rapid temperature reduction via double-sided direct contact heat transfer, forming fine ice crystals quickly to fully preserve the cellular structure of raw materials. It maximally retains the original flavor, juice and nutrition of ingredients, greatly reduces product dehydration loss, and improves the yield rate and premium value of finished products.

The core freezing plates of the equipment are made of food-grade aluminum alloy with outstanding thermal conductivity and high heat exchange efficiency. The frame, pipelines and chamber body of the whole machine adopt SUS304 stainless steel, paired with high-density polyurethane insulation layers for excellent cold retention performance. It meets hygienic standards for food contact, with smooth surfaces easy to rinse and sanitize, suiting the routine cleanliness management requirements of food factories. Equipped with an independent hydraulic station and hard-chrome wear-resistant cylinders, it delivers stable lifting and compression with adjustable pressure and low leakage risk. Built-in intelligent electronic control system supports customized freezing duration and temperature parameters, realizing the full process of compression, quick freezing, pressure relief and discharging with one click. It is easy to operate and can be monitored by a single operator, applicable to multiple scenarios such as onshore processing plants and ocean-going fishing vessels.

Compared with tunnel quick-freezing equipment, the hydraulic plate freezer features a compact structure and smaller footprint. It requires no high-flow supporting fans and achieves lower overall energy consumption, making it flexible for renovation projects with limited space in small and medium processing plants, aquatic terminals and fishing vessel decks. It is widely used for quick-freezing of aquatic products such as fish fillets, fish paste, shrimp and shellfish, as well as cut meat, small-packaged poultry, boxed prepared dishes and fruit & vegetable blocks. It serves as the preferred fresh-locking equipment for standardized processing of export aquatic products and prepared food, delivering neatly shaped and stable-quality frozen products that satisfy the high standards of foreign trade orders.
