Plate Freezer
The Plate freezer is suitable for frozen blocks, such as fish, shrimp, surimi, meat, pet food, juice, etc. Our Plate freezers are commonly used for freezing brick-shaped products in mold or boxes. In plate freezers, refrigerant is allowed to circulate inside thin channels within the plates.
The packaged products are firmly pressed between the plates. High rates of heat transfer can be obtained between the packaged product and the evaporating plates.

Key Features
Unique one-piece insulated enclosure with better insulation and strength.
Full stainless steel structure with good appearance, easy to clean.
Aluminum-alloy evaporative plate with better freezing capacity.
Separate liquid supply and suction for each plate, even supply with high efficiency and better freezing performance.
Mass production, freeze in blocks.
High Efficiency
Made out of seawater-resistant aluminum, food grade, the 25mm thick Square aluminum plate gives high strength, high corrosion resistance, and thermal conductivity. Our plate is automatically welded and has minimum deformation.
Good Insulation Performance&Easy To Clean
The enclosure is insulated with one piece of Polyurethane foaming to ensure a robust structure and minimize the cold loss by eliminating the joints. Our plate freezer’s enclosure is stainless steel. It can sustain the harsh marine environment and is easy to clean.
