Cabinet and Loading Structure
- Dual-cabinet structure, the two cabinets open independently; a single cabinet can be opened on its own, one cabinet cooling while the other is loaded.
- Overall dimensions 1900 × 940 × 2150 mm, single-cabinet inner cavity 580 × 720 × 1430 mm, single-cabinet volume 0.597 m³, total of two cabinets 1.194 m³.
- The cabinet interior is 304 stainless steel plate, and the insulation layer is PU polyurethane integral foaming.
- Rack 460 × 600 × 1370 mm, 30 standard trays per cabinet; matching trolley 2000 × 1040 × 2250 mm, materials go in and out of the cabinet on the trolley.
- The evaporator defrosts on a set cycle (electric heating or hot-gas defrost); check the door gasket regularly, as a poor door seal will affect cooling.
Refrigeration System and Cooling
- The refrigeration system consists of a compressor, finned-tube evaporator, air-cooled condenser and piping; unlike vacuum blast chillers, this machine does not include a vacuum system.
- Evaporating temperature -40℃, cabinet interior can reach -45℃, a relatively large temperature difference; the evaporator fan drives cold-air circulation inside the cabinet, and air-duct guide plates distribute the air supply, with cold air blowing directly across the food surface to carry away heat.
- The condensing method is air-cooled with a built-in fan, requiring no cooling water connection; it can be changed to a water-cooled configuration, confirmed per order.
Control System and Operation
- Thermostat or PLC with touch screen, running automatically according to the set discharge target temperature; the discharge temperature is adjustable within the range of 3～10℃.
- Core temperature is measured by inserting a probe thermometer into the center of the material; an infrared thermometer gun reads surface temperature and cannot replace it.
- Select 220V or 380V according to site conditions, power cable 2.5 square, grounding and circuit breaker according to installation requirements.
Application Scenarios
| Scenario | Description |
|---|---|
| Cooked food processing | Braised products, roasted meats, soy-braised meat, loading at 85～95℃, target 10～25℃ |
| Bakery products | Bread, cake, mooncakes, loading at 80～90℃, target 20～25℃ |
| Meat processing | Ham, sausage, meatballs, loading at 75～85℃, target 10～15℃ |
| Central kitchen | Prepared dishes, catering, loading at 80～90℃, target 10～20℃ |
| Fast-food chains | Rice, side dishes, loading at 80～90℃, target 15～25℃ |
In cooked-food and soy-braised workshops, products go into the cabinet on the trolley right after coming out of the pot, replacing natural spread cooling; bakery and pastry items can be packaged once past the cooling stage, with the target temperature set at 20～25℃.
The same series also includes DKN-RHC-60D-80, with the same exterior and single-cabinet inner dimensions, the difference being the refrigeration configuration and cabinet temperature; see food blast chillers. For batches of several hundred kilograms or more, or continuous production with packaging, see liquid nitrogen freezers; where materials need direct contact with the cooling medium for heat exchange, see immersion chillers.
Installation Conditions
- Site: reserve trolley passage and cabinet door opening space according to overall dimensions, and leave heat-dissipation distance around the condenser.
- Power: 220V / 380V optional, configure a 2.5 square power cable according to the machine’s total power and provide proper grounding.
- Medium: air-cooled models require no external cooling water; when changed to water cooling, cooling water and a cooling tower need to be provided on site, confirmed per order.
- Exhaust and environment: the condenser discharges heat to the environment, so keep the installation location ventilated; the cabinet belongs to a cooked clean area, cleaned per shift, and not shared with the raw-material area.
Warranty and After-Sales
One-year warranty for the whole machine; a solution is provided within 2 hours of receiving a request, arrival on site within 24 hours, and fault clearance within 72 hours; one free on-site service per year, with lifetime technical support.
Frequently Asked Questions
How much material can DKN-RHC-60D-45 hold per batch, and how long does cooling take?
30 standard trays per cabinet, 3～5 kg per tray, about 100 kg per batch per cabinet and about 200 kg for both cabinets. Single-batch cooling takes 1～2 hours, depending on food type and loading temperature; run a test with your own material before production.
Cooked food enters the cabinet at 60～90℃; what discharge temperature is suitable?
The discharge temperature is adjustable within the range of 3～10℃. Braised products, roasted meats and soy-braised meat commonly use 10～25℃, while bread and mooncakes can be set at 20～25℃; after cooling, transfer to the 0～4℃ refrigeration stage as soon as possible.
Does this equipment need liquid nitrogen?
No. Cooling capacity is produced by the compressor and evaporator, with heat dissipated by the air-cooled condenser; there is no vacuum system in the machine, and no liquid nitrogen storage tank is connected. For liquid nitrogen deep-low-temperature applications, see liquid nitrogen freezers.
What power distribution capacity is needed?
Total power is about 4.55 kW, power supply 220V / 380V optional, power cable 2.5 square; power distribution capacity and grounding are determined according to installation requirements.
What are the practical differences of the dual-cabinet model compared with the single-cabinet model?
The two cabinets open independently, so they can be used in staggered mode: one cabinet cooling while the other is loaded, and the single-batch loading amount adds up according to the number of cabinets.
To check the cabinet model against your product and batch weight, go to contact us and describe your single-batch loading amount, individual piece thickness, loading temperature and target temperature.
