DKN-RFT-1612 is the 1600 mm wide mesh belt model in the Kunning Cryo mesh belt freezer product line: mesh belt width 1600 mm, mesh belt length 12 m, with compressor refrigeration as the cold source. Material is spread onto the stainless steel mesh belt from the infeed end, travels continuously through the low-temperature zone with the mesh belt to complete freezing, and then exits from the discharge end. It is suitable for aquatic products, meat and poultry, prepared dishes and other production lines requiring continuous feeding and stable rhythm. The equipment does not require a liquid nitrogen storage tank or low-temperature piping; it can operate once connected to power on site and with condensation and heat dissipation conditions in place; working temperature, cooling capacity and freezing cycle are configured according to customer materials and capacity, confirmed at the time of order.

Structure and Configuration
The equipment is a continuous tunnel structure, composed of four parts: insulated enclosure, mesh belt conveying system, evaporator and cold air circulation system, and control system.
- Insulated enclosure: inner and outer walls are formed from SUS304 food-grade stainless steel plate, with rigid polyurethane foam insulation layer in between to reduce cooling loss; the enclosure has access doors for cleaning and routine maintenance.
- Mesh belt conveying system: stainless steel mesh belt with variable frequency speed control motor and tensioning device, conveying speed continuously adjustable, infeed and discharge ends can be connected with upstream and downstream processes.
- Evaporator and cold air circulation: evaporator with axial flow fans and air guide plates, cold air circulates for heat exchange on both upper and lower sides of the mesh belt, allowing material surfaces to quickly pass through the ice crystal formation zone.
- Control system: PLC plus touch screen control, PID automatic adjustment, temperature measurement using PT100 platinum resistance; with over-temperature alarm, emergency stop switch, grounding and phase sequence protection and other safety designs.
Applicable Scenarios
| Scenario | Description |
|---|---|
| Aquatic processing | Continuous IQF of fish, shrimp, shellfish, requiring rapid passage through the ice crystal formation zone |
| Meat and poultry processing | Continuous production lines for cut meat, poultry block freezing and IQF |
| Prepared dishes and prepared foods | Multi-category switching, calling different mesh belt speeds and temperature programs according to product |
| Pastry and fruit/vegetable granular materials | Continuous quick freezing of granular and small block materials |
For batch-type, multi-variety small-batch production, cabinet equipment can be considered (liquid nitrogen quick freezing cabinet); for how to choose between liquid nitrogen refrigeration and mechanical refrigeration, see Comparison of Liquid Nitrogen Quick Freezing and Mechanical Refrigeration Quick Freezing.
Installation Conditions
- Site: reserve space for operation, maintenance and infeed/discharge connection according to equipment external dimensions (external dimensions confirmed per order).
- Power: 380V/50Hz, wiring and grounding according to total power and site power distribution capacity.
- Heat dissipation: compressor condenser requires ventilation or cooling water conditions, the workshop should reserve heat dissipation space and maintenance access.
- Floor and drainage: calculate floor load-bearing according to equipment fully loaded weight; the workshop should set slope and drainage ditches according to cleaning and drainage requirements.

Frequently Asked Questions
What does 1612 in DKN-RFT-1612 represent?
According to Kunning Cryo equipment numbering rules, the numeric segment for tunnel and mesh belt models is “mesh belt width (mm÷100) + mesh belt length (m)”, so 1612 means mesh belt width 1600 mm and mesh belt length 12 m. Mesh belt size determines the conveying surface of a line, not equal to hourly capacity.
Does this equipment use liquid nitrogen or a compressor?
It uses compressor refrigeration, i.e. mechanical refrigeration. Unlike liquid nitrogen quick freezing tunnels, it does not require a liquid nitrogen storage tank or low-temperature piping; it can operate once connected to power on site and with condensation and heat dissipation conditions in place, and operating costs are unrelated to liquid nitrogen prices.
How are capacity and freezing time calculated?
Piece weight, spreading thickness, infeed temperature, target core temperature and shift output requirements need to be provided, calculated according to specific materials; mesh belt speed is variable frequency adjustable, and freezing cycle can be adjusted with product. The parameter table does not list fixed hourly capacity precisely because capacity varies with material, and writing it as fixed would be misleading.
What are the working temperature, cooling capacity and total power?
These three items are configured according to customer materials, capacity and site power conditions; there are no fixed values in the technical data, confirmed per order. After working conditions are confirmed, we provide the corresponding selection parameters and power distribution requirements.
What discharge core temperature can be achieved?
Quick freezing conditions are calculated at material core temperature below -18℃; the specific achievable value is related to material thickness, moisture content, and residence time in the low-temperature zone, confirmed per order.
