Rapid Freezing for Commercial Food Operations
Our 28-Tray Commercial Blast Freezer is a high-capacity rapid freezing system designed for bakeries, hotels, restaurants, catering businesses, supermarkets, and food processing plants. With 28-pan capacity and advanced refrigeration technology, this blast freezer quickly lowers food temperatures from +70°C to -18°C within 240 minutes, preserving freshness, texture, and nutritional value.
Unlike standard freezers that freeze food slowly (causing large ice crystal formation that damages cell structure), our blast freezer uses rapid airflow and powerful refrigeration to freeze food quickly. This forms smaller ice crystals, preserving the original texture, flavor, and appearance of baked goods, meats, seafood, and prepared meals. The result is higher-quality frozen products that taste fresh when thawed.
The digital control panel allows you to set precise freezing temperatures (-40°C to +10°C) and cooling cycles, with programmable recipes for different food types. The stainless steel interior and removable trays make cleaning quick and easy, while the energy-efficient compressor and thick insulation reduce operating costs and maintain consistent temperatures.

Q: What is the difference between a blast freezer and a regular freezer?
A: A regular freezer cools food slowly (typically 4-12 hours), causing large ice crystals to form that damage cell structure, resulting in texture loss and flavor degradation when thawed. A blast freezer uses rapid airflow and powerful refrigeration to freeze food quickly (240 minutes or less), forming smaller ice crystals that preserve the original texture, flavor, and nutritional value. Blast freezers are essential for commercial food operations where quality is paramount.
Q: How long does it take to freeze food?
A: Freezing time depends on food type, quantity, and initial temperature. Under optimal conditions, our blast freezer can lower food temperature from +70°C to -18°C within 240 minutes. For smaller items like pastries and individual portions, freezing time can be as short as 90-120 minutes. For larger items like whole chickens or large roasts, allow 3-4 hours for complete freezing.
Q: What is the maximum temperature range?
A: Our blast freezer can maintain temperatures from -40°C to +10°C. The wide temperature range makes it suitable for both rapid freezing (typically -30°C to -40°C) and temporary holding/chilling (0°C to +10°C). The digital control panel allows you to set precise temperatures and cooling cycles for different food types.
Q: Is it easy to clean and maintain?
A: Yes! The stainless steel interior is smooth and non-porous, making it easy to wipe clean. The removable trays and shelf supports can be washed separately. We recommend defrosting and cleaning the interior weekly with a mild detergent and warm water. The condenser coil should be cleaned every 3-6 months to maintain energy efficiency. Door gaskets should be inspected regularly and replaced if damaged.
Q: What voltage and power does it require?
A: Our 28-tray blast freezer is available in 220V/380V, 50/60Hz configurations (three-phase power recommended). The power consumption is approximately 3kW-5kW depending on the model and operating conditions. We can customize the voltage and plug type for your specific country and requirements. A dedicated electrical circuit with proper grounding is required for safe operation.
