Jackstone Vertical Plate Freezer Package

• Rapid freezing of fish blocks, meat patties, and other seafood products.
• Preservation of fruits and vegetables in bulk for further processing.
• Freezing of liquid or semi-liquid products in trays or pouches.
• Used in large-scale food processing plants and fishing vessels.
• Suitable for products requiring quick freezing to maintain quality and texture.

Typical capacity

Vertical plate freezers of this class commonly offer freezing capacities ranging from 500 kg to several tonnes per batch, depending on plate size and number of stations.

Power supply

Units of this type typically require a robust three-phase electrical supply, commonly 400V, 50Hz, with significant amperage to power both the freezer plates and the associated refrigeration plant.

Refrigerant type

While this unit specifies Freon 404a, modern or reconditioned systems may use alternative refrigerants, and buyers should verify compatibility with current environmental regulations.

Plate spacing

The 100mm plate spacing mentioned is typical for freezing larger blocks or products, allowing for efficient heat transfer and accommodating various product thicknesses.

Footprint

A package including two freezers and a refrigeration plant will require a substantial industrial footprint, with specific dimensions depending on the exact model and layout of the components.

Throughput

Throughput for a two-unit system with 20 stations each would be considerable, allowing for continuous or high-volume batch freezing operations.

Construction materials

Typically constructed from stainless steel for hygiene and durability in food processing environments, with robust frames to withstand industrial use.

• What maintenance is typically required for a used vertical plate freezer?

  Regular maintenance includes checking the refrigeration system for leaks, inspecting hydraulic components, cleaning plates, and verifying the integrity of seals and hoses. Electrical systems also require periodic inspection.

• Can this type of freezer be used for different product sizes?

• What are the typical installation requirements for a package like this?

• Is Freon 404a still a commonly used refrigerant in the UK?

• What is the benefit of a vertical plate freezer over other freezing methods?

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.
