During the growth of lemons, their surfaces typically accumulate substantial impurities. These include soil, dust, leaf debris, and microorganisms. Such contaminants not only compromise the lemons’ appearance but may also affect food safety. If sold untreated, the fruit’s surface often appears dull and coarse, significantly reducing consumer purchasing interest and consequently lowering market prices.
This fruit washing line is specifically designed for lemons. Through this washing line, it is possible to:
- Thoroughly remove impurities from the lemon surface.
- Enhance the visual quality of lemons.
- Achieve standardised grading for sales.
- Extend storage life.
Lemon Washing Process:
A complete lemon fruit washing line typically comprises multiple stages, with each component working in tandem to form a continuous automated production process.
- Washing
Washing constitutes one of the core steps in the fruit washing line. Common washing methods combine spray washing with roller brush cleaning. This approach not only rapidly removes soil and impurities but also avoids damaging the fruit peel.
- Air-drying
After washing, the surface of lemons retains a certain amount of moisture, which must be removed using air-drying equipment. This not only prevents subsequent processes from being compromised but also enhances the effectiveness of the waxing treatment.
- Grading
Grading systems are typically carried out by automated sorting machines. Depending on specific customer requirements, systems can be configured for grading based on size, weight, sugar content, and other parameters, enabling precise classification of lemons.
- Waxing
Waxing is a crucial step in enhancing the commercial value of lemons. When food-grade fruit wax is evenly sprayed onto the lemon surface, it forms a protective coating that not only improves the fruit’s lustre but also reduces moisture evaporation, thereby extending its storage life.
- Packaging
Finally, the processed lemons are conveyed to the packaging area. Depending on sales requirements, various packaging methods may be employed, such as: mesh bag packaging, carton packaging, pallet packaging, etc.
Application of the Lemon Fruit Washing Line
Although this production line is primarily designed for lemon processing, its application extends beyond lemons. Featuring a flexible design, the equipment is equally suitable for washing and grading various citrus fruits and certain round fruits, such as:
Oranges, Tangerines, Limes, Pomelos, Apples, Pears
Consequently, this industrial lemon washing machine is suitable not only for lemon plantations and fruit processing plants, but also for large-scale fruit and vegetable wholesale markets and export processing enterprises.
