We know equipment longevity depends on proactive care, especially when machines like our GMJY-2000 Fruit & Vegetable Cleaner (Capacity: 500–700 kg/h) aren't in regular use. Here's how to safeguard your investment during downtime:
1. Power Down Safely
Disconnect Properly: Use the dedicated air switch in your circuit to cut power completely. For the GMJY-2000 (rated 8–10A at 28KHz), this prevents voltage surges from damaging its ultrasonic transducers.
Secure Wiring: Ensure the 380V power cord and grounding wire (marked with yellow-green insulation) are dry and free of corrosion.
2. Empty & Dry the System
Drain All Fluids: Residual water or cleaning agents can corrode the stainless steel tank. Tilt the machine to remove trapped liquid.
Dry Thoroughly: Wipe the tank, conveyors, and ultrasonic vibrators with microfiber cloths. Leave the lid open for 24–48 hours to air-dry.
3. Protect Critical Components
Transducer Care: Apply a thin layer of LERFORD's anti-oxidation gel (included in maintenance kits) to transducer surfaces.
Electrical Safeguards: Cover the control panel and motor with waterproof dust covers. Store in a low-humidity area (<60% RH).
4. Avoid Environmental Hazards
No Harsh Chemicals: Never store flammable or acidic substances near the machine. Even inactive, fumes can degrade seals.
Temperature Control: Keep storage areas between 10°C–30°C to prevent rubber part cracking.
5. Pre-Storage Maintenance Checklist
Inspect Filters: Clean or replace the GMJY-2000's sediment filters (part #LF-2000F).
Lubricate Moving Parts: Use food-grade silicone spray on conveyor rollers.
Update Firmware: For smart models, sync with LERFORD's app to install latest updates.
6. Reactivation Protocol
After prolonged storage:
Refill Correctly: Add clean water until the tank reaches the 700L mark (GMJY-2000's max capacity).
Test Gradually: Run a 10-minute cycle without produce to check for leaks or abnormal noises.
Calibrate Ultrasonics: Use a frequency meter to confirm transducers operate at 28KHz ±1%.
