ZKJB-300II Vacuum Cooling Meat Mixer
A compact twin-shaft platform for 200–220 kg-class batches that require controlled air inclusion and tighter temperature management. Specify the cooling duty around your formulation—the published evidence confirms the mixer, while the thermal package remains project-defined.

Compact temperature-managed mixing
Vacuum performance with a clearly defined cooling boundary
HELPER's Chinese catalog names this model ZKJB-300II Vacuum Cooling Mixer. Its body specification matches the established ZKJB-300 vacuum platform: a sealed 300 L chamber, parallel twin shafts, reversible operation and pneumatic lid and discharge functions. HELPER Group material also states that cooling can be supplied as an option for special applications.
Unlike the separately tabulated 650 L and 1,200 L cooling machines, no independent English cooling schedule was found for the 300 L model. This page therefore presents verified base-machine values and treats jacket design, added power, weight, envelope, refrigeration equipment and guaranteed temperature change as quotation-controlled data.

Control the variables that shape batch quality
Seal and evacuate
Close the pneumatic lid and establish the recipe vacuum without uncontrolled foaming or liquid carryover.
Mix and cool
Run the validated shaft speed and reversal pattern while monitoring product and coolant temperatures.
Vent and discharge
Restore pressure safely, confirm endpoint uniformity and transfer promptly to filling, forming or packing.

Compact sealed twin-shaft construction
- Parallel shafts circulate ingredients across and along the chamber.
- 84/42 rpm published operating speeds support controlled recipe development.
- Pneumatic lid and discharge actions simplify the operating sequence.
- Stainless chamber and external surfaces support hygienic cleaning procedures.
- Vacuum mixing can limit entrained air and improve distribution in cohesive recipes.
- Control hardware and component brands should be confirmed for the destination market.
- No separate refrigeration skid is shown in the exact official photograph.
Do not assume that “II” automatically includes a chiller. Define whether the supply includes a jacket and connections only, or a complete loop with tank, pump, refrigeration unit, valves, hoses, sensors and integrated controls.

Cooling configuration required: the values above describe the repeatedly documented 300 L vacuum mixer platform. No independent official ZKJB-300 Cooling row confirms the final weight, dimensions, power or heat-exchange performance. Layout and procurement must use the approved ZKJB-300II GA and utility schedule—not the base-machine envelope alone.
Thermal design
Turn “cooling option” into measurable performance
Start with batch mass, product specific heat, ingredient start temperature, desired endpoint and allowable mixing time. Add estimated mechanical heat and ambient gain. The resulting duty establishes the required jacket area, coolant supply temperature, flow, return-temperature rise and refrigeration recovery capacity.
For chilled water or glycol, confirm approved medium, concentration, connection size, design pressure, condensation control and drainage. Review insulation, jacket welds and access around utility connections during sanitation assessment. Where the plant provides utilities, define a clean interface; where it does not, quote the entire thermal loop as one system.
Selection fit
Choose the configuration by process need
Standard ZKJB-300
Suitable when ingredients are pre-chilled and the existing room and cycle already protect endpoint temperature.
ZKJB-300II jacketed
Add a heat-exchange boundary when the plant can supply a stable, correctly sized coolant circuit.
Complete cooling package
Specify mixer, jacket, pump, tank, chiller, instrumentation and controls together when a guaranteed cooling curve is required.
Factory acceptance
Test with the actual formulation and utilities
Mixing result
Check ingredient distribution, texture, binding, residual air and temperature at multiple chamber positions.
Cooling curve
Log product temperature plus coolant inlet, return, flow and pressure against time for the agreed batch.
Safety sequence
Verify lid, vacuum, vent and discharge interlocks, emergency stop and safe recovery after utility interruption.
Hygiene release
Inspect product-contact surfaces, seals, drainability and access, then document cleaning and inspection intervals.
Buyer questions
ZKJB-300II Cooling FAQ
Is 220 kg the guaranteed working batch?
It is the published maximum for the base ZKJB-300. Confirm the practical range using your product density, fill level, viscosity and mixing objective.
Does ZKJB-300II include refrigeration equipment?
The public pages do not define the complete scope. Require a line-item bill covering jacket, ports, pump, tank, chiller, valves, piping and controls.
Can the standard dimensions be used for factory layout?
Only provisionally. Cooling jackets, insulation and utility connections can change service clearances and final envelope, so use the approved cooling GA.
Was an exact operating video verified?
No stable exact ZKJB-300II cooling run was found. A generic vacuum mixer video is not presented as proof; request a run-off video and cooling log for the quoted configuration.
