How it works

• Load & Push: Place loaded trays onto the trolley and wheel it into the sealed chamber.
• Precise Spray: Precision nozzles spray nitrogen to instantly absorb heat and flash-freeze products.
• Forced Convection: Internal fans circulate ultra-cold air evenly, eliminating temperature gradients.
• Smart Control: PLC system automatically adjusts LN2 flow based on real-time sensor feedback.
• Harvest: Door unlocks automatically once the preset core temperature (e.g., -18°C) is reached.

Typical Industries / Applications

• Seafood processing: sea cucumber, prawn, shellfish, fresh fish quick-freezing.
• Berry & fruit producers: freeze strawberries, blueberries to retain moisture and taste.
• Cooked food factories: freeze ready meals and premium cooked dishes for retail supply.
• Meat processing workshops: marinated meats and specialty cured products.
• Food R&D and labs: small-batch freezing for trials and formula development.

Features of the instant cabinet freezer

• Full SUS304 construction for food safety and easy cleaning.
• Intelligent PLC + touch control for one-click automatic running and manual adjustments.
• Anti-freeze heated door seal to prevent door sticking and limit cold loss.
• Built-in oxygen depletion alarm and other safety monitoring devices.
• Mobile brake casters for easy relocation and flexible installation.

Advantages over traditional blast freezing equipment

• Lower initial investment: no large compressor/condenser civil works required.
• Ultra-fast freezing speed reducing moisture loss and preserving product quality.
• Compact footprint suitable for small factories and limited production spaces.
• Flexible batch production: rapid on/off operation to match irregular small-batch schedules.
• Improved product value by protecting cellular integrity via rapid cryo-freezing.

FAQs (selected)

• Q: What affects the liquid nitrogen freezer price?
  A: Price depends on voltage requirements, optional extras (for example data logging software), and any custom options; final pricing varies by configuration.
• Q: Do I need to buy an LN2 tank from the supplier?
  A: The unit is supplied with an LN2 hose interface and can connect to standard LN2 storage tanks available locally.
• Q: How much liquid nitrogen does the machine consume per hour?
  A: Consumption depends on product thickness, moisture content, and initial temperature; typical consumption is approximately 0.5–0.8 kg LN2 per 1 kg food for many products, but exact figures vary by product.
• Q: Can the machine be used for both freezing and chilling?
  A: Yes. The blast chiller supports multi-stage programming to allow freezing or chilling profiles (for example transitioning cooked product from +90°C to -18°C in stages).
• Q: Are OEM or custom tray sizes available?
  A: Yes, OEM/ODM customization of inner tray dimensions, additional safety devices, or control panel language is supported.
