Article guide
1. Equal rated power does not create equal production
Both products publish a 15 kW rating, but the vessel diameter, total depth, machine footprint, and diner reference differ. A larger vessel can hold more material, yet the same rated input does not make every larger batch heat in the same time. Starting temperature, viscosity, mixing, evaporation, and handling all matter.
Ask the operational question
For each menu item, determine the safe working fill, net batch requirement, complete cycle, discharge method, and time needed to restore the station.
2. Compare verified specifications first
| Item | 60 cm model | 80 cm model |
|---|---|---|
| Model | G60-15-443 | G80-15-430 |
| Power and supply | 15 kW, 380 V/50 Hz | 15 kW, 380 V/50 Hz |
| Diameter and published pot depth | 60 cm, 200 mm | 80 cm, 200 mm |
| Total pot depth | 43 cm | 45 cm |
| Raised height | 20 cm | 20 cm |
| Pot material | 443 stainless steel | 430 stainless steel |
| Machine dimensions | 800×900×800 mm | 1000×1100×800 mm |
| Published diner reference | 60-100 | 200-300 |
Diner figures support initial screening only. Confirm effective working volume, fill limits, and menu cycle with the supplier and loaded trials.
3. Classify the menu by physical load
Four useful load groups
| Load | 60 cm tendency | 80 cm tendency | Shared check |
|---|---|---|---|
| Clear liquid | Smaller service waves and quicker changeover | Larger, less frequent batches | Starting temperature, heat-up, holding boundary |
| Noodles or floating foods | Potentially easier split batches and retrieval | Consider when a larger surface is needed | Fill line, movement, retrieval method |
| Viscous sauce | Smaller load may reduce mixing burden | Use only with an appropriate mixing plan | Local overheating, sticking, cleaning |
| Braised solid food | Medium loads and frequent flavor changes | Large pieces or larger single batches | Liquid ratio, loading, receiving container |
4. Put changeover inside the capacity equation
Complete cycle outranks nominal diameter
A 60 cm vessel may use more batches but recover faster in a varied menu. An 80 cm vessel may reduce batch count for one product but take longer to load, discharge, and clean. Measure the total workflow.
| Field | Why it changes selection |
|---|---|
| Net volume and mass | Shows whether a larger vessel is necessary |
| Discharge method | Large hot liquid or solids change handling risk |
| Flavor change and cleaning | May dominate a mixed-menu schedule |
| Peak batch count | Determines large-and-few versus small-and-frequent strategy |
5. Treat space and human motion as hard limits
The 80 cm model is published as 200 mm wider and 200 mm deeper. Add front working space, side tools, delivery turns, cleaning access, and service clearance. A larger diameter also changes loading reach, observation, mixing, retrieval, and discharge.
On-site mock-up
- Use the actual operator height to simulate reaching and mixing.
- Place the planned ingredient, utensil, and receiving containers.
- Ensure hot liquids or heavy loads do not cross an aisle.
- Confirm that drainage, cleaning, and service access remain open.
6. Verify electrical design for the whole project
Both pages publish 380 V/50 Hz, 15 kW, and copper coils. That does not authorize connection to any existing circuit. A qualified electrical professional must review the nameplate, concurrent equipment, isolation, protection, earthing, and local rules. This article does not prescribe cable or breaker sizes.
7. Compare five-year ownership using one menu
| Dimension | 60 cm effect | 80 cm effect |
|---|---|---|
| Station | Smaller footprint | Larger footprint and support zone |
| Operation | May require more batches | Same rating but potentially larger load; measure cycle |
| Labor | Lighter batch handling | May need assistance for loading, discharge, and cleaning |
| Menu flexibility | Potential advantage for frequent changeover | Potential advantage for one large repeated product |
| Downtime exposure | Smaller batch loss | Interruption can concentrate more product in one batch |
8. Avoid three misleading shortcuts
- Do not select from diner count alone; menus and service waves differ.
- Do not select from diameter alone; effective fill, mixing, and discharge define usable capacity.
- Do not select from 15 kW alone; starting conditions and physical properties determine the cycle.
- Do not turn a product-page feature statement into an untested food-quality guarantee.
9. Frequently Asked Questions
Will the 80 cm vessel heat more slowly because both models are 15 kW?
Diameter alone cannot answer that. Measure the actual load, starting temperature, physical properties, and complete cycle.
Can the published diner count select the model?
Use it only for screening. Convert diners into menu demand, service waves, and accepted batches.
Do the two vessels use the same stainless steel?
The 60 cm page lists 443 stainless steel and the 80 cm page lists 430 stainless steel. Confirm material documentation in the purchase file.
Does an 80 cm vessel always reduce labor?
No. Fewer batches may be offset by heavier loading, mixing, discharge, and cleaning.
Can cable and breaker size be chosen from the 15 kW figure?
No. A qualified electrical professional must design from the nameplate, project load, installation method, and local requirements.
10. About the Source and Supplier Verification
This article uses current Fengzhida product pages as equipment-fact sources while keeping the advice neutral. Before purchase, require the supplier to confirm the model, configuration, utilities, acceptance method, and service boundary in a quotation or specification sheet.
Source verification date: 2026-08-27. Product facts come from the listed Fengzhida pages. The workflows, formulas, and checklists are decision tools, not performance, capacity, or compliance guarantees.
