FAQ

1. What is the difference between flash freezing and conventional freezing?

Flash freezing achieves temperatures of -18°C in 30–90 minutes compared to 4–24 hours for conventional methods. This rapid freezing creates smaller ice crystals, preserving cellular structure and reducing drip loss when thawed.

2. What products are suitable for flash freezing?

Flash freezers handle a wide range: seafood (fish, shrimp, shellfish), meat (cuts, patties), poultry, fruits, vegetables, bakery products, and prepared foods. The high air velocity requires products to be relatively uniform in size.

3. How is the freezing time determined?

Time depends on product type, initial temperature, thickness, and target temperature. The PLC control system includes preset programs optimized for common products, or operators can create custom programs.

4. What is the energy consumption?

Energy consumption varies by model and product. Typical consumption is 0.08–0.15 kWh per kg of frozen product. Variable speed fans and heat recovery options can further reduce energy use.

5. Can we integrate flash freezing into production lines?

Yes, we offer conveyor-fed flash freezers for continuous operations, as well as batch loading options for facilities with discrete production.

6. What maintenance is required?

· Daily: Clean chamber, check door seals

· Weekly: Check refrigerant levels, inspect fans

· Monthly: Clean condensers, calibrate sensors

· Quarterly: Professional service inspection

7. What power supply is required?

Standard models require 380V/3-phase/50Hz power. Total power consumption ranges from 25KW to 180KW depending on capacity. A dedicated power connection is recommended.

8. Do you provide installation and training?

Yes, we offer complete installation, electrical connection, refrigeration system commissioning, and operator training. Refrigeration technician coordination is included.

9. What is the typical lead time?

Standard models: 20–30 days. Custom configurations: 30–45 days. Large-scale projects may require additional time for engineering.

10. Are eco-friendly refrigerant options available?

Yes, we offer models using R449A, R290 (propane), or CO2 transcritical systems for facilities requiring low-GWP refrigerants.
