DSI - 2021 DSI H - 7/9

• Freezing of packaged fish fillets, seafood, and shellfish.
• Rapid freezing of meat products, including burgers and minced meat blocks.
• Preservation of poultry portions and processed chicken products.
• Freezing of certain fruit and vegetable products in block form.
• Batch freezing of liquid or semi-liquid products in trays or pouches.

Typical capacity

For this class of horizontal plate freezer, capacities commonly range from 500 kg/hr to over 2000 kg/hr, depending on product thickness and freezer plate count.

Power supply

Units of this type typically require a three-phase industrial power supply, commonly 400V/50Hz in the UK, with specific amperage requirements varying by refrigeration capacity.

Freezing method

Double-contact freezing, utilising direct contact between the product and refrigerated plates for efficient heat transfer.

Plate dimensions

Plate sizes vary, but commonly accommodate standard tray or carton dimensions for efficient loading.

Refrigerant type

Modern systems often use ammonia (R717) or CO2 (R744) as primary refrigerants, particularly in larger industrial setups.

Hydraulic system

Features a hydraulic system for plate compression, ensuring consistent product contact and efficient freezing.

Footprint

The overall footprint, especially with an integrated refrigeration container, will be substantial and requires adequate space for installation and maintenance access.

• What kind of products can be frozen with a DSI H-series plate freezer?

  These freezers are primarily designed for freezing products in uniform blocks or packages, such as fish fillets, meat blocks, poultry, and certain prepared foods. The double-contact method is highly efficient for flat products.

• What are the advantages of horizontal plate freezing?

• What maintenance is typically required for a plate freezer?

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

• What are the typical installation requirements?

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.
