Blast freezer liquid nitrogen blast freezer blast freezers

It is a plate-type blast freezer designed for rapid freezing of foods (fish, meat, seafood, fruits, vegetables). It features precise temperature control, stainless steel 304 construction, PLC control and is intended for industrial and commercial food-preservation applications.

The product name references liquid nitrogen, but the provided specifications list refrigerant R-404A, which indicates a mechanical refrigeration configuration. Please confirm with the supplier which configuration (LN2 or R-404A mechanical) you are purchasing, since installation, operation and safety requirements differ.

The unit supports temperature control in the ranges -80°C to 0°C and -40°C to 0°C, allowing very low-temperature freezing for different product needs.

The specification lists 220V voltage and a power rating of 1.7 kW. Verify local electrical compatibility and whether a dedicated circuit or special wiring is required for installation.

External dimensions are 880 × 740 × 1320 mm (L × W × H) and the unit weight is approximately 200 kg. Plan for sufficient floor loading capacity and space for service access.

It is suitable for freezing fish and seafood, various cuts of meat, prepared foods, fruits and vegetables. As a plate freezer, it works especially well for flat or packaged items that can be pressed between freezing plates.

Freezing time depends on product type, thickness, initial temperature, packaging and load size. Thin, single-layer products freeze much faster than large or dense blocks. For specific throughput and cycle-time estimates, provide sample product details to the supplier.

The machine is described as easy to operate and uses a PLC (programmable logic controller) for temperature control and automation. Basic operator training is recommended to ensure safe and efficient use.

The interior is stainless steel 304 for hygienic cleaning. Routine maintenance includes regular cleaning with food-safe detergents, inspecting door seals and plates, draining and defrosting as needed, and following the manufacturer's service schedule for refrigerant circuit checks. Any refrigerant or compressor service should be performed by qualified technicians.

Follow general cold-guard and food-safety practices: wear appropriate PPE to prevent cold burns, ensure adequate ventilation (especially if using LN2 to avoid oxygen depletion), avoid confined-space exposure to cryogens, and train staff on emergency procedures. Confirm the unit type (LN2 vs mechanical) to apply correct safety measures.

The unit is made from stainless steel 304, which is corrosion-resistant, easy to clean and suitable for food-industry hygiene standards.

The product listing mentions online support service. For on-site service, preventive maintenance plans, spare parts or warranty details, contact the supplier or manufacturer directly.

Yes — it is suitable for restaurants, catering services and food-processing facilities that require rapid freezing to preserve quality, provided the electrical and space requirements are met.

Obtain spare parts and refrigerant-system service through the manufacturer or authorized service providers. Refrigerant work must be performed by certified refrigeration technicians in accordance with local regulations.
