We provide end-to-end customization for the freezer’s internal volume, layout, refrigeration power, and accessory matching, based on your actual production needs. Whether you need to freeze 240kg of bread per hour or other specific output targets, we can design a solution that perfectly matches your production scale, with full compatibility for standard and custom bakery trolleys.
The equipment is equipped with a world-renowned Bitzer screw compressor, paired with an evaporative condenser and ceiling-type aluminum tube aluminum fin air cooler, delivering strong and stable refrigeration performance. The core refrigeration valves adopt internationally renowned brands such as Danfoss, ensuring reliable operation, fast cooling speed, and precise temperature control to meet the strict freezing requirements of bread products.
The warehouse body uses 150mm thick double-sided stainless steel polyurethane insulation panels with a density of 40±2kg/m³, connected by eccentric hooks with seamless sealing treatment, minimizing cold loss and reducing energy consumption. The freezer door is equipped with a safety locking device that supports emergency escape from inside the warehouse, paired with moisture-proof LED lighting and IP65 rated electrical components, ensuring safe operation in high-humidity bakery production environments.
The independent electrical control system adopts core components from ABB, Schneider, and Siemens, with real-time temperature automatic control and stepless energy regulation functions. It can adjust the refrigeration output according to actual loading and temperature conditions, reducing unnecessary energy consumption while ensuring stable freezing effect, and lowering long-term operation costs for production enterprises.
This blast freezer is suitable for commercial bread bakeries, frozen baked goods manufacturers, central kitchen bakery facilities, and pastry and dessert processing enterprises. It is primarily used for batch freezing of finished bread, pre-baked bakery products, pastry items, dough blocks, and other bakery-related products. It can also be adapted for freezing of flour products, seafood, and prepared foods, meeting diverse batch freezing needs in food production.
Absolutely. Our design team will tailor the freezer’s volume, refrigeration power, and internal layout based on your production requirements, such as the 240kg per hour bread freezing capacity requested by our long-term bakery client, to ensure the equipment fully meets your output targets.
The freezer is equipped with an internal emergency escape safety door lock, moisture-proof explosion-proof LED lighting, waterproof copper core cables, and IP65 rated electrical components, fully adapting to the high-humidity, high-frequency operation environment of bakery workshops, and ensuring the safety of operators and equipment.
