Jackstone Froster Vertical Plate Freezer

• Freezing of whole fish or fish fillets into compact blocks for efficient storage and transport.
• Processing of meat products, such as minced meat or offal, into uniform frozen blocks.
• Freezing of certain fruit and vegetable purees or pulps for later use in food manufacturing.
• Production of frozen blocks of pet food ingredients.
• Batch freezing of liquid or semi-liquid food products within suitable packaging.

Typical freezing capacity

For this class of equipment, freezing capacity commonly ranges from 500 kg to several tonnes per batch, depending on plate size and number.

Plate gap

Commonly found plate gaps on units of this type are between 50mm and 150mm, accommodating various block thicknesses.

Refrigerant type

Units typically operate with refrigerants such as Freon (R22, R404A) or ammonia, depending on the system design and age.

Number of stations

Vertical plate freezers commonly feature between 10 and 30 freezing stations, influencing throughput.

Power supply

Typically requires a 3-phase industrial electrical supply, commonly 400V, 50Hz in the UK, with varying amperage requirements based on compressor size.

Footprint

Overall dimensions for this class of equipment can vary significantly, but typically range from 2m to 5m in length, 1.5m to 2.5m in width, and 1.5m to 2.5m in height.

Construction material

Freezing plates are typically made from aluminium, while the frame and external panels are commonly stainless steel or painted mild steel.

• What are the main advantages of a vertical plate freezer?

  Vertical plate freezers offer rapid freezing, efficient use of floor space, and produce uniformly shaped blocks, which are beneficial for storage and transport.

• What type of products are best suited for a vertical plate freezer?

• What maintenance is typically required for this equipment?

• Can this unit be integrated into an existing processing line?

• What are the typical power consumption considerations?

• Are spare parts readily available for Jackstone Froster equipment?

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.
