Advantages of Tunnel-Type Freezers:
1. Stainless steel conveyor belt;
2. 150mm thick sandwich-type polyurethane foam board, composited with stainless steel on both sides; complete floor panel included;
3. Door equipped with frame heating device;
4. Aluminum evaporator with varying fin spacing;
5. Axial fan: stainless steel air box, aluminum blades;
6. A single welded stainless steel drain plate installed above the floor panel. It drains defrost water from the cabinet through multiple stainless steel drain pipes.
7. Air intake, exhaust, and all structural components are made of stainless steel;
8. Control panel made of stainless steel;
9. Siemens brand electronic components;
10. Gearbox from a well-known brand;
11. Short-time freezing with excellent cross-ventilation, freezing time from 10 to 50 minutes;
12. Works with a dual-speed motor, expanding application range while saving energy. 13. Air blowers are classified into different types according to different frozen products, such as left-right cross blowing, mixed blowing, and top blowing, so as to achieve perfect freezing effect, ensure product quality and improve efficiency.
MATTON Refrigeration Units
The refrigeration unit consists primarily of four basic components:
Compressor: Compresses the refrigerant into a high-temperature, high-pressure gas. We partner with international brands such as Bitzer, Mayekawa (MYCOM), and RefComp.
Condenser: Converts the high-temperature gas into liquid and dissipates heat.
Throttling device (expansion valve): Reduces the pressure and temperature of the liquid refrigerant.
Evaporator: Absorbs heat from the surrounding environment while converting the refrigerant into gas. In certain quick-freezers handling high-temperature product inputs, the evaporator is crucial for maintaining low internal temperatures.
As the core component of the quick-freezer, the refrigeration unit is the foundation of most technical advantages. MATTON supports various refrigeration unit configurations—such as two-stage screw compressor units or cascade refrigeration systems (e.g., CO₂/NH₃ or Freon cascade)—to ensure high cooling efficiency at low evaporation temperatures.
Refrigeration units utilizing NH₃ or CO₂ are becoming increasingly popular worldwide; MATTON develops and supplies these systems globally in compliance with international refrigeration regulations.
Why Choose MATTON Tunnel Freezers?
Simply put, for the same production capacity, power consumption is lower; for the same power consumption, production capacity is higher. MATTON always puts the customer first, manufacturing our machines with sincerity.
| ITEM | MATTON | OTHER | REMAKE | |
| 1 | Effective storage capacity | Effective storage capacity = internal net length × net width = 12.1 × 2.5 = 30.25 m² | Effective storage capacity = net length × net width = 7.96 × 2 = 15.92 m² | When freezing time and infeed density are the same,
freezer capacity determines production output. |
| 2 | Evaporator | Wide fin pitch; 30 mm fin pitch on the air intake side. | Slice spacing ≤ 20 mm | The spacing of the air intake vanes is too wide, resulting in poor freezing performance. |
| 3 | Air Speed and Freezing Effect | The raised base plate structure improves the point of impact for the cold airflow on frozen products, preventing the loss of cooling capacity and reducing electricity consumption. | With the bottom plate lowered, it is difficult for the same fan to achieve the ideal air velocity; this inevitably leads to a loss of cooling capacity and increased power consumption. Cleaning is difficult. | |
| 4 | Import/Export and Goods In/Out Section | Adjustable stainless steel wind-blocking and thermal insulation unit for entry and exit points.
Five-sided thermal insulation for the loading/unloading bay. |
The adjustment mechanism for the flexible entry/exit curtains lacks thermal insulation.
There is no five-sided thermal insulation system for the loading/unloading bay. |
|
| 5 | Wind speed | Adjustable, 4–5 m/s。 | It is not adjustable, and there is no accurate data. | |
| 6 | transmission | Full-length stainless steel drive shaft; prevents scale buildup and is easy to clean. | Nylon roller shafts spaced close together; dirt between the shafts cannot be cleaned out. |
