Traditional cleaning methods are no longer able to meet the challenges of pesticide residues in modern agriculture. Running water only removes 30% of surface pesticide residues, saltwater soaking can damage the nutrients in fruits and vegetables, and chemical cleaners can cause secondary contamination. Coreal Machinery has compiled some information for your reference.
1. Industry Background and Pain Points: Limitations of Traditional Cleaning Methods
In the food processing industry, fruit and vegetable cleaning, as a key pre-treatment step, directly impacts product quality and production efficiency. Core Pain Points of Traditional Cleaning Methods:
- Efficiency Bottleneck: Manual cleaning can only process 20-30 kg of fruits and vegetables per person per hour. Large processing plants require dozens of people working simultaneously daily, with labor costs accounting for as much as 35%.
- Cleaning Blind Spots: Spray cleaning only removes surface dirt, leaving less than 60% of pesticide residue removed from wrinkles and crevices, posing a significant risk of microbial contamination.
2. Technical Advantages: The Core Competitiveness of Commercial Ultrasonic Cleaners
Deep Cleaning and High-Efficiency
- Pesticide Residue Removal Rate ≥ 90%: Far exceeding the 65% of manual cleaning and the 75% of spray cleaning.
- Microbial Killing Rate ≥ 99.9%: Elimination of pathogens such as Escherichia coli and Staphylococcus aureus meets standards.
- Continuous Processing Capacity: Mainstream models can process 800-2000 kg of fruits and vegetables per hour, meeting the needs of large-scale production.
3. Maintenance
Daily Maintenance Key Points
- Daily: Clean the tank filter, check the vibrator surface cleanliness, and discharge wastewater.
- Weekly: 5% Circulate citric acid solution for descaling and check belt tightness.
- Monthly: Ultrasonic power calibration (maintaining ±5% of rated value) and seal replacement.
- Annual: Transducer array inspection and insulation resistance test (≥100MΩ).
