Manually sorting pineapples has long been a challenge for the industry. Manual weight estimation leads to inconsistent grading and mixed sizes; selling ungraded batches drives down overall prices, while low efficiency and high labor costs result in slow shipments during peak seasons—severely impacting sales volume and profitability. This manual-feed pineapple weight grader is specifically designed for the characteristics of large pineapples. It is ideal for small-to-medium-sized farms, cooperatives, and processing plants requiring lightweight, cost-effective solutions to the grading challenge.

1. Precise Weighing & Standardized Grading: Equipped with high-precision load cells, the system offers gram-level sorting accuracy with minimal grading error. It supports customizable weight ranges—allowing for the separation of premium, large, medium, and small sizes—resulting in uniform product grading that is perfect for premium gift boxes, supermarket supply, and wholesale/retail channels, thereby easily commanding a price premium.
2. Manual Loading & Hassle-Free Operation: Designed for manual fruit loading, the system eliminates the need for complex feeding mechanisms. It accommodates the large size and heavy weight of pineapples, effectively preventing jams or blockages. Operation is simple, featuring a one-touch control panel for parameter adjustments; a single operator can manage the line, and beginners can get up to speed quickly, significantly lowering operational and maintenance barriers.
3. Gentle Handling & Damage Prevention: Features specialized flexible loading cradles and a cushioned discharge structure that contours to the pineapple's shape. The transport process involves no squeezing or bruising, maximizing the integrity of the fruit's surface, minimizing sorting-related damage, and significantly increasing the yield of marketable fruit.
4. Compact, Durable & Versatile: With a small footprint and high mobility, the machine is suitable for various environments, including processing workshops, warehouses, and harvest sites. Constructed from food-grade stainless steel, it is waterproof, rust-resistant, and easy to clean—ideal for the humid conditions typical of fruit and vegetable processing—while offering robust durability and a low failure rate.
