Description of mango washing waxing drying and sorting processing line
The mango washing waxing drying and sorting processing line is an integrated intelligent equipment system designed specifically for post-harvest mango processing, covering the entire process from initial fresh fruit handling to standardized grading. Whether small or medium-sized mango growing cooperatives or large fruit and vegetable processing companies, this mango processing line enables automated, standardized, and efficient mango processing, effectively addressing the pain points of incomplete cleaning, uneven waxing, large grading errors, and high waste rates associated with traditional manual processing.
Mango Washing Line Processing
- Loading: An inclined conveyor loader, controlled by variable frequency drive, gently transports the mangoes to the next process, preventing damage to the fresh fruit. The loading capacity can be flexibly adjusted based on the needs of subsequent processes, adapting to different processing scales.
- Washing: The mangoes enter the brush washer, where the brushes continuously tumble, thoroughly removing impurities such as mud, pesticide residue, and fruit hairs from the surface. A filtered circulating water tank is also included to filter and reuse the wash water, saving water and protecting the environment.
- Waxing: After washing, the mangoes are drained and transferred to the waxing machine, where edible-grade fruit wax is atomized and sprayed. High-pressure nozzles evenly coat the mangoes' surface with the wax, forming a dense protective film.
- Air-Drying: After waxing, the mangoes enter the hot air circulation dryer, which utilizes multiple sets of inclined air knives and an adjustable-speed conveyor belt. The hot air temperature and speed can be flexibly adjusted according to the mango variety. Strong, three-dimensional wind sweeping quickly removes excess wax and moisture from the mangoes' surface, ensuring even drying of the wax layer while preventing mold and mildew caused by residual moisture.
- Grading: After drying, the mangoes enter an intelligent grading machine. Using high-precision weighing sensors and an optical inspection system, the mangoes are automatically graded based on multiple criteria, including weight, size, color, and defects. Grading accuracy reaches ±5g, and the grading speed can reach up to 1,000 mangoes per hour. The graded mangoes are collected through different outlets and directly shipped to packaging.
Advantages of the mango washing waxing drying and sorting processing line
Significantly Improved Processing Efficiency: The entire production line utilizes automated control, requiring only 2-3 operators per line. This represents a 5-8 times improvement in efficiency compared to traditional manual processing, easily meeting the processing needs of large-scale mango harvests during peak seasons.
Reduced Fresh Fruit Loss: The entire process, from conveying, cleaning, and grading, utilizes a flexible handling design. Combined with precise parameter control, this effectively reduces mango damage from collisions and crushing, reducing processing losses from the traditional 15%-20% to under 5%.
Ensuring Consistent Processing Quality: Standardized cleaning, waxing, and grading procedures ensure consistent cleanliness, wax layer thickness, and size across each batch of mangoes, enhancing their appearance and product grade, helping the product enter the high-end market.
Energy Saving and Environmental Protection: Equipped with a water circulation and filtration system and waste heat recovery equipment, the system increases water utilization by over 60% and reduces electricity consumption by 20%. Furthermore, the use of edible-grade, environmentally friendly fruit wax ensures compliance with food safety standards, balancing economic and environmental benefits.
