截至2026年，出口买家和中央厨房选商用洗菜机，不能只看清洗速度。TY-106（20-30kg/batch）和DXC-400（30-40kg/batch）怎么匹配产能、电压、用水量？本文给出5项技术协议要点、耗水量测算与8项FAT验收清单。
截至2026年，商用洗菜机选型投诉集中在三处：批次容量虚标、耗水量无核算、清洗后菌落总数超标。本指南以TY-106和DXC-400两款机型为案例，拆解选型逻辑，为出口买家和中央厨房提供5项技术协议要点、耗水量测算与8项FAT验收清单。
1. Real Throughput: Capacity vs. Line Speed
The most common mistake is confusing processing volume with actual throughput. TY-106 rates 20-30kg/batch at 3-5 min/cycle; DXC-400 rates 30-40kg/batch at 3-5 min/cycle. Real numbers:
- TY-106: 30kg divided by 4min times 60min equals 450kg/h (theoretical); practical stable throughput approximately 350-400kg/h including loading, washing, unloading and tank cleaning
- DXC-400: 40kg divided by 4min times 60min equals 600kg/h (theoretical); practical stable throughput approximately 500-550kg/h
The bottleneck stage determines true line throughput. If upstream cutting runs at 800kg/h and you install a TY-106, the entire line slows to 400kg/h. Acceptance is based on 3-batch continuous average; single peak readings are not used as acceptance criteria.
2. Water Consumption: A Mandatory Item for Export Projects
Middle East and Southeast Asia buyers always check unit product water consumption during factory acceptance. Field test data (April 2026 production line test):
| Model | Per Batch | Per Hour | Per Tonne Raw Material |
|---|---|---|---|
| TY-106 | 120-150L/batch | approximately 1800-2250L | approximately 4.5-5.0m3/tonne |
| DXC-400 | 180-220L/batch | approximately 2700-3300L | approximately 5.0-5.5m3/tonne |
DXC-400: 2.25kW motor, 380V/50Hz three-phase, measured approximately 2.7-3.3m3/h water consumption — 15% lower than comparable models on the market due to shorter turbulent wash flow path. TY-106: 2HP water pump plus 1HP hydraulic pump, approximately 2.2kW, 380V/50Hz. Water quality requirements in technical protocol: total hardness not more than 150mg/L, pH 6.5-8.5, chloride ion not more than 50mg/L.
3. Material and Hygiene Design
Both models use 304 stainless steel (GB 4806.9-2016 food contact material), but details differ:
- TY-106 inner tank: 700 by 700 by 620mm, perforated plate 1.2mm, drawn without weld seams; suitable for leaf-heavy light-wash applications
- DXC-400 inner tank: 700 by 700 by 620mm, perforated plate 1.5mm, tapered drain at tank bottom — no water pooling; suitable for root vegetables and high-soil loads
Key hygiene design check points: not less than 5mm gap between inner tank and outer housing (prevents liquid stagnation and mold growth, GB 14881-2013 Section 5.3.2); drain outlet fitted with stainless steel strainer to prevent material debris blocking the drain; outer shell should be one-piece drawn, not welded panels (welded seams trap soil and harbor bacteria).
4. Five Technical Protocol Items (Must-Negotiate Before Signing)
- Minimum throughput: both parties jointly test on supplier machine, 3-batch average not less than 90% of rated value
- Maximum water consumption: per tonne raw material not exceeding 5.5m3 (based on supplier test report)
- Water quality: buyer site water must meet total hardness not more than 150mg/L, otherwise water softener required
- Material certificate: 304 stainless steel material report (GB 4806.9-2016) and food contact material compliance declaration
- Cycle time: loading plus washing plus rinsing plus unloading per batch no more than 6 minutes total
5. Eight FAT Acceptance Checklist Items
| No. | Item | Acceptance Criteria |
|---|---|---|
| 1 | No-load run test | 30 min operation, bearing temperature rise not more than 35 degrees C, no abnormal vibration or noise |
| 2 | Full-load wash test | 3-batch average not less than 90% of rated capacity; no visible soil residue on washed product |
| 3 | Water consumption measurement | Record actual water use per batch; calculate not more than 5.5m3 per tonne raw material |
| 4 | Inner tank hygiene check | No weld seam cracks, perforated edges free of burrs, tank bottom drains freely |
| 5 | Electrical safety | Grounding resistance not more than 0.1 ohm; insulation resistance not less than 2M ohm; emergency stop response not more than 0.5s |
| 6 | Material verification | 304 stainless steel material certificate matches physical unit |
| 7 | Water pump performance | TY-106 pump flow not less than 3.5m3/h (head 5m); DXC-400 pump flow not less than 5.0m3/h (head 6m) |
| 8 | Accessories list | Spare seal ring times 2, pump strainer times 1, tool kit times 1 |
6. Selection Recommendation: Match Your Line Rhythm
For central kitchens processing 10-15 tonnes per day, TY-106 (single unit, stable 350-400kg/h) with manual feeding meets requirements. For more than 20 tonnes per day with continuous line, DXC-400 with conveyor feeding delivers higher throughput and better water efficiency. Both models use 380V/50Hz three-phase power; export projects to Southeast Asia where grid is 220V/60Hz require transformer or custom motor specification.
FAQ
Q: Which model suits root vegetable washing?
A: DXC-400. Tapered tank bottom drain and 1.5mm reinforced inner tank handle high-soil loads from potatoes, radish and similar produce without water pooling, delivering approximately 12% higher wash cleanliness than TY-106.
Q: Does high water hardness affect wash performance?
A: Yes. Hardness more than 150mg/L causes scale buildup on heating coils and spray nozzles, reducing wash uniformity and eventually clogging spray holes. Install water softening equipment at the inlet, or use DXC-400 integrated descaling rinse function.
Q: What certifications are required for Southeast Asia export?
A: CE certification (EU) or target-market hygiene certification is prioritized. Nameplate must show voltage (380V/50Hz three-phase or as per buyer requirement), power, manufacturer info and GB standard number.
Q: Can wash cycle time be adjusted?
A: Both TY-106 and DXC-400 support adjustable wash time (0-10 min settable). Set 5-6 min for high-soil load produce; 3-4 min sufficient for leaf vegetables to avoid excessive leaching of nutrients.
Q: Site requirements for installation?
A: Equipment entrance clearance not less than 1800 by 1200mm (overall unit dimension); floor load capacity not less than 600kg/m2; water inlet DN25, drain DN50; equipment requires reliable grounding, resistance not more than 0.1 ohm.
Q: What is the lead time for both models?
A: TY-106 standard configuration lead time approximately 15-20 working days; DXC-400 approximately 20-25 working days. Actual lead time subject to written confirmation; peak season may extend delivery.
