AIR BLAST FREEZER (ABF) ROOM PT. BJT INDONESIA
An Air Blast Freezer (ABF) is a common type of freezing room filled with chilled air. Its advantage lies in utilizing convection currents to efficiently distribute cold temperatures throughout the room. However, the convective heat transfer coefficient of air tends to be small, requiring longer freezing times due to the low rate of heat transfer. The larger the room, the smaller the amount of heat that can be transferred in a given time. Weight loss of products can also occur due to direct contact between the product and water, which can lift the water content in food products, especially if the temperature and humidity allow.
How Air Blast Freezer Works
The cooling process involves a simple compressor machine that induces condensation, which is then transferred through expansion valves before reaching the evaporator room. The evaporator itself is a part of the cooler that vaporizes food items to low temperatures. Inside, the pressure from the refrigerant will become low pressure so that a high temperature or heat can be released.
This can happen when the refrigerant gas has been sucked by the compressor while the condenser only functions to transfer heat into cold dew, which then becomes liquid refrigerant.
The next task will be carried out by the compressor, which is to lower the temperature to change the form of solid ice. Freezing gas refrigerant or freezing in this way is excellent for preserving food because it will not spoil its taste.

Sandwich Panel Features
When it comes to constructing a reliable and efficient cold storage facility, the choice of sandwich panel features plays a crucial role in ensuring optimal insulation and durability. Let's delve deeper into each component to understand its significance:
Skin Material: The skin material of the sandwich panel is crafted from pre-painted galvanized steel, with a thickness of 0.5mm. This high-quality material is specifically designed for food-grade applications and is sourced from NS-Bluescope, a renowned provider of premium steel products. The pre-painted surface offers enhanced corrosion resistance and aesthetics, while the galvanized steel base provides structural integrity and longevity.
Skin Color: The skin of the sandwich panel is available in two color options: Rabbit white and Off white. These neutral hues not only complement various architectural styles but also contribute to a clean and professional appearance.
Insulation Material: The core insulation material of the sandwich panel is made of polyurethane (PU), a highly effective thermal insulator known for its low thermal conductivity and excellent moisture resistance. With an insulation density ranging from 40 to 45 kg/m³, the PU foam ensures superior thermal performance, minimizing heat transfer and maintaining stable temperature conditions within the cold storage facility.
Panel Thickness: The sandwich panel is available in two thickness options: 150mm and 200mm. The choice of panel thickness depends on the specific requirements of the cold storage application, with thicker panels offering enhanced insulation properties and structural stability.
Floor System: The floor system of the cold storage facility can be customized to suit different preferences and operational needs. Options include a PU foam + concrete combination, sandwich panel flooring, or a checkered aluminum (2mm) surface (Aluminum Bordes). Each flooring option offers unique benefits in terms of durability, hygiene, and ease of maintenance.
Door Type: The cold storage facility can be equipped with either swing doors or sliding doors, depending on space constraints and user preferences. Swing doors provide easy access and are ideal for smaller spaces, while sliding doors offer efficient utilization of space and smooth operation in larger installations.
Knockdown System: The sandwich panel features a knockdown system with easy-to-install cam locks, allowing for quick and hassle-free assembly and disassembly. This modular design facilitates flexible configuration and adaptation to changing storage requirements, making it an ideal choice for dynamic environments.
Heavy-Duty Hinge & Handle: The door hinges and handles are engineered for heavy-duty use, ensuring long-lasting performance and reliability. The safety door lock system enhances security and prevents unauthorized access, safeguarding valuable inventory and maintaining product integrity.
Plastic Curtain: The sandwich panel includes a plastic curtain with a 20% overlapping design, providing additional insulation and preventing heat infiltration. This feature helps optimize energy efficiency and temperature control within the cold storage facility, contributing to operational cost savings and environmental sustainability.
Compressor: The cold storage facility is equipped with a semi-hermetic two-stage compressor manufactured by BITZER Germany, renowned for its reliability, efficiency, and durability. The compressor ensures consistent cooling performance and precise temperature control, essential for preserving perishable goods.
Condenser: The condenser unit, supplied by reputable brands such as Guntner, HD, or equivalent BITZER Germany models, efficiently dissipates heat from the refrigerant, maintaining optimal operating conditions for the cooling system.
Evaporator: The evaporator, provided by trusted manufacturers such as Guntner or Muller, facilitates the evaporation of refrigerant, effectively cooling the air within the cold storage facility. Its high-quality construction ensures efficient heat exchange and uniform temperature distribution.
Electric Power: The cooling system operates on 380 V electrical power, compatible with 3-phase supply at a frequency of 50 Hz. This standard electrical configuration ensures reliable performance and compatibility with existing power infrastructure.
Temperature Range: The cold storage facility offers a temperature range from -35°C to -40°C, suitable for preserving a wide range of perishable goods, including frozen foods, pharmaceuticals, and biological samples. The precise temperature control enables compliance with industry regulations and ensures product quality and safety.
