1. Convert place settings into basket loads
A “place setting” may include a tray, bowl, cup, and cutlery, or it may mean a project-specific combination. Deep bowls and large plates occupy different space. Build a standard basket from actual dishware at the required spacing and record piece count, weight, and exposure to steam and hot air.
Create a site-specific basket standard
- Document plate, bowl-and-cup, and mixed loads with a photo and count.
- Do not stack or compress dishware merely to claim capacity.
- Separate fragile and heavy items and record handling requirements.
2. Compare the published cabinet data
| Item | LZ-ZQ1 single door | LZ-ZQ2 double door |
|---|---|---|
| Rated power and supply | 3100 W, 220 V/50 Hz | 3200 W, 220 V/50 Hz |
| Process | Steam plus hot-air drying | Steam plus hot-air drying |
| Baskets | Four deep baskets, 510×380×150 mm | Four deep baskets in each of two chambers |
| Published capacity | 340 L, about 120 settings | 680 L, about 240 settings |
| Dimensions | 650×700×1900 mm | 1260×700×1900 mm |
| Published diner reference | 50-100 | 150-200 |
| Body | 201 non-magnetic stainless steel, casters | 201 non-magnetic stainless steel, casters |
The pages do not publish a complete cycle, water use, independent chamber-control details, or continuous-duty limits. Put these items in the RFQ and acceptance sheet.
3. Size from the complete turnover cycle
Program time is not basket turnover time
The complete cycle begins with dirty-dish sorting and ends when clean dishware can enter protected storage. Sorting, pre-rinse, loading, queue, program, drying, cooling, unloading, and reset all consume capacity.
| Time block | Site record | Capacity effect |
|---|---|---|
| Sorting and pre-rinse | Minutes per basket and queue | A slow front end starves the cabinet or creates a dirty backlog |
| Loading and program | Door, setting, steam, drying | Determines cabinet occupancy |
| Cooling and unloading | Safe-touch time and labor | Often missing from theoretical output |
| Reset | Cleaning, refill, inspection | Determines the next start time |
4. Use a single door for a clear line and a double door for defined parallel work
| Situation | Single-door tendency | Double-door tendency |
|---|---|---|
| One main return wave and narrow room | Narrower station with simple ownership | May consume excessive lateral space |
| Two dining areas or dish groups | Requires time separation | Can support chamber assignment after control verification |
| Highly variable demand | Straightforward small batches | May offer reserve, subject to single-chamber operating conditions |
| Concentrated peak and adequate clean storage | May require repeated cycles or two units | Offers parallel potential |
5. Write chamber-management rules
Two doors do not create clean-to-dirty zoning
Both chambers remain inside one dishwashing room. Crossing staff, floors, baskets, and storage can still recontaminate clean items. Assign chambers by dining area, dish material, return wave, or accountable team, then support the rule with labels, baskets, and logs.
- Confirm whether each chamber can start, stop, and show status independently.
- Fix each chamber's purpose rather than improvising at peak time.
- Use color or numbers to separate dirty and clean basket states.
- Move completed loads to protected clean storage, not back to pre-rinse.
6. Space planning extends beyond 650 and 1260 mm
Both pages list 700 mm depth and 1900 mm height. Add door opening, basket removal, caster locking, drainage, steam environment, ventilation, cleaning, and service space. A double-door unit may have two people unloading at once, so simulate the peak aisle and receiving positions.
Acceptance observations
- Load and unload the actual basket at its highest planned weight.
- Observe how steam, hot air, and condensate are managed.
- Verify protected storage immediately after processing.
- Document how an interrupted load is reprocessed rather than released.
7. Include baskets and labor in five-year cost
| Cost group | Single-door plan | Double-door plan |
|---|---|---|
| Equipment and space | Narrower unit; quantity can scale | Wider single unit may replace side-by-side equipment |
| Operation | Measure power, water, and drying by actual load | Measure after confirming single- and double-chamber modes |
| Baskets | Working and reserve basket inventory | Parallel chambers need clearer identification and more simultaneous baskets |
| Labor | Simple line may create one loading bottleneck | Parallel work may require coordinated staffing |
| Downtime | Single-unit failure is concentrated | Redundancy depends on chamber construction and controls |
8. Do not publish 240 settings as peak throughput
- Published capacity omits the actual dish mix, spacing, and complete cycle.
- Two chambers do not automatically mean two independent systems.
- A larger cabinet does not repair a slow pre-rinse, cooling, or clean-storage stage.
- Diner count ignores multiple items per person and multiple return waves.
9. Frequently Asked Questions
Is the 680 L double-door model two fully independent 340 L systems?
The page publishes two chambers and total capacity but not the complete independence and redundancy boundary. Confirm this in the specification and acceptance test.
Can 120 and 240 settings be converted directly into hourly output?
No. Actual basket occupancy, program, drying, cooling, unloading, and reset time are also required.
Is the single-door unit limited to 50-100 diners?
That is a published reference. Size from dish pieces, return waves, and measured complete turnover.
Can one chamber hold dirty dishes while the other stores clean dishes?
Do not treat door count as zoning. Design clean-to-dirty flow across the entire room, basket system, and storage area.
How many extra baskets are required?
Calculate baskets simultaneously in pre-rinse, cabinet occupancy, cooling, and clean storage, then confirm physical compatibility.
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.
