Vegetable and fruit washing production lines, through automated operation, greatly improve washing efficiency and capacity, effectively reducing labor costs and intensity. They thoroughly remove surface dirt, pesticide residues, and most microorganisms, significantly improving product cleanliness, safety, and hygiene standards. Simultaneously, the gentle washing method better protects the appearance of fruits and vegetables, reducing damage, and extends shelf life through subsequent preservation treatments, making it a key link in ensuring the quality and scale of modern food processing.
