Jackstone Froster Vertical Plate Freezer

• Rapid freezing of whole fish, fish fillets, and other seafood products.
• Batch freezing of meat blocks, poultry, and offal in industrial settings.
• Freezing of liquid products in trays or bags, such as fruit purees or concentrates.
• Suitable for high-volume production lines requiring efficient freezing cycles.

Typical capacity

For this class of equipment, freezing capacities typically range from 500 kg to 5,000 kg per batch, depending on product and plate configuration.

Power supply

Commonly requires a 3-phase industrial power supply, typically 400V/50Hz, with associated motor power for the hydraulic system and refrigeration compressor (if integrated).

Plate configuration

Units of this type commonly feature 20 to 30 stations, with plate gaps typically between 50mm and 100mm, influencing block thickness.

Refrigerant type

Typically designed for use with common industrial refrigerants such as Ammonia (NH3) or various HFCs, depending on the specific refrigeration plant it connects to.

Freezing time

Freezing times for products like fish blocks are typically 2 to 4 hours, influenced by product thickness, initial temperature, and refrigerant temperature.

Construction material

Frames are commonly galvanised steel for durability in harsh environments, with freezing plates typically made from extruded aluminium for efficient heat transfer.

Footprint

A vertical plate freezer of this configuration typically requires a floor area of approximately 2m x 2m to 3m x 3m, plus space for maintenance and loading/unloading.

• What is a vertical plate freezer used for?

  Vertical plate freezers are primarily used for rapidly freezing products into uniform blocks, such as fish, meat, or liquid products, by direct contact with refrigerated plates. This method ensures efficient heat transfer and consistent product quality.

• What are the benefits of using a vertical plate freezer?

• What maintenance is typically required for this type of equipment?

• Can this freezer be integrated into an existing refrigeration system?

• What are the considerations for installation?

Plate freezers are valued for their efficiency in rapid product freezing across food processing applications. Buyers typically appreciate their compact footprint and consistent performance. When purchasing used equipment, inspecting plate condition for corrosion or damage is essential, as worn plates reduce freezing efficiency. Key strengths include reliable operation, relatively straightforward maintenance requirements, and suitability for batch processing. Industry sentiment favours models from established manufacturers with documented service histories. Buyers should verify refrigeration system integrity and confirm spare parts availability before committing to purchase.
