Plate Freezer

The Plate Freezer is a China-manufactured batch contact-freezing system by Lynxcool Industrial Refrigeration, designed for fish, shrimp, meat and specialty seafood processing plants globally. Comprising stacked hollow aluminium alloy freezing plates within an insulated stainless steel cabinet, it circulates refrigerant at −35°C to −40°C through internal plate channels.

As a leading China-origin solution, the Plate Freezer delivers 3–5 times faster freeze times than blast air freezing for equivalent product thickness, offering superior energy efficiency and space utilization. The integrated cabinet minimizes heat ingress, while flexible stainless steel hoses connect plates to the refrigerant circuit.

Hydraulic cylinder assembly controls plate closing/opening for easy loading/unloading, and all units undergo full assembly and testing at our China production facility. Compatible with R404A, R507A, R448A, R449A and R717 (ammonia) refrigerants, it meets diverse industrial freezing needs.


Main components and functions


·  Double-sided contact freezing: Simultaneous top/bottom freezing cuts cycle time by 3–5x vs. blast air freezing.

·  Hydraulic pressing: Eliminates air gaps to boost conductive heat transfer by up to 10x.

·  Space-efficient design: Vertical plate stack maximizes throughput per unit footprint.

·  Aluminium alloy plates: Die-cast with uniform temperature distribution, lightweight and corrosion-resistant.

·  Food-grade insulation: 100mm+ polyurethane foam cabinet with stainless steel construction ensures hygiene and thermal efficiency.

·  Dual configurations: Horizontal (tray/block loading) and vertical (specialized applications) options available.

·  Multi-refrigerant compatibility: Supports ammonia and all standard HFC/HFO refrigerants.

Application Scope


1.Fish Block Freezing

Lynxcool's plate freezer is the global standard for fish block freezing. Fish, fillets, and mince are pressed into uniform blocks under hydraulic pressure, freezing 3-4 times faster and using less energy than blast freezing. It’s perfect for both small and large-scale fish processors.


2.Shrimp Block Freezing

The plate freezer ensures shrimp are frozen into solid blocks with minimal ice crystals. This preserves texture, color, and reduces drip loss, providing premium quality at block-freezing efficiency. It’s ideal for shrimp exports.


2.Minced Meat and Processed Meat Blocks

Minced meat is frozen into precise blocks, minimizing oxidation and bacterial growth. The plate freezer uses food-grade materials, ensuring hygienic and accurate freezing for portioning and further processing.


3.Squid, Cephalopods and Seafood

Whole squid, octopus, and other seafood are pressed into uniform blocks, compacted with adjustable hydraulic pressure to avoid tissue damage. This solution is ideal for both on-board and shore-based freezing.


4.Ready Meals and Packaged Food

Ready meals, soups, sauces, and other packaged foods are frozen between plates, ensuring uniformity and preventing deformation. The flat freezing surface maximizes retail display space and meets food safety standards.
