Walk-in Blast Freezer: Optimised Bulk Trolley Logistics for High-Volume Meat Processing

De BFR-500 Walk-In Blast Freezer is de ideale oplossing voor de logistieke uitdagingen rondom grootschalige invriezing in grote vlees- en pluimveeverwerkingsinstallaties. Deze robuuste shock-freezing faciliteit is ontworpen om volledig beladen rollend-in karren direct vanaf de productievloer te accepteren, waardoor handmatig laden per tray overbodig wordt. Door een extreem hoge luchtstroom van -40 graden Celsius over batches van 500 kg te sturen, wordt de kerntemperatuur van dikke primairstukken of verpakte pluimvee razendsnel teruggebracht naar -18 graden Celsius. Dit stopt de bacteriële groei en voorkomt vochtverlies tijdens de cruciale koelfase.

Højeffektiv termodynamisk teknik

To freeze half a tonne of dense biological material in just a few hours, one requires a combination of sheer thermodynamic power and precise aerodynamic control. The BFR-500 achieves this by utilising a heavy-duty Bitzer two-stage screw compressor mounted on an external skid, delivering massive cooling capacity without leaking heat or noise into the main production area.

• Loft-mounted dual-discharge evaporators:De grote axiale ventilatoren zuigen de terugkerende lucht krachtig door de centrale verdampingsblok en blazen vrieskoude lucht met kracht langs beide tegenoverliggende wanden. Dit creëert een turbulente wervelstroom die diep tussen de trolleyrekken doordringt, waardoor de binnenste trays met exact dezelfde snelheid bevriezen als de buitenste trays.
• 150 mm Cam-Lock isolering:Given that the ambient air within the factory is warm and highly humid, the room is built using 150mm thick polyurethane panels. These panels feature an interlocking design driven by internal eccentric cams, creating an airtight and vapour-proof seal that effectively eliminates thermal leakage and external condensation.
• Versterkte vloerverwarming:Standard concrete flooring is prone to frost heave and cracking when subjected to extreme static loads in sub-zero temperatures. In contrast, the BFR-500 is equipped with an insulated, SUS304-reinforced floor featuring integrated low-voltage heating cables. This design prevents ice expansion and ensures the structural integrity required to safely support the weight of steel trolleys at maximum capacity.

Integratie met de logistiek voor de verwerking van vleesproducten

In high-capacity slaughterhouses, the time spent handling livestock is a direct driver of labour costs. As the internal floor is designed to be perfectly level with an external loading ramp (or built directly into the factory floor), workers can seamlessly wheel trolleys from the primary butchery stations straight into the cold room. This seamless logistical flow is essential when incorporating the freezer into a large-scale industrial setup.slagtelinje til fjerkræhvor hundredvis af fugle skal nedkøles samtidigt, før de pakkes. Når frysestadiet er fuldført, rulles vognene glidende videre til palleteringszonerne, hvilket sikrer, at de tunge maskiner fraindustriel vleesverwerkingsapparatuursectorerne står aldrig stille og venter på, at der bliver ledig plads i kølerummet.

Defrosting and Airflow Control for Industrial Use

Processing meat with high moisture content inevitably releases a vast amount of water vapour, which causes ice to build up rapidly on the evaporator coils. To ensure that freezing efficiency remains at 100 per cent during back-to-back 500kg production runs, the system features an automated hot-gas defrost cycle. When pressure sensors detect a drop in static airflow—a clear sign that ice is bridging across the aluminium fins—the logic controller temporarily reverses the refrigerant flow. This melts the ice block directly into a heated drain pan in a fraction of the time taken by standard electric induction heaters, allowing operators to load the next trolley immediately without any significant downtime.
