Project Background
India is one of the world's major pineapple-producing countries, with pineapple exports growing steadily in recent years. International markets have imposed increasingly stringent requirements on the size standardization of export-grade produce.
Our company recently delivered a Manual Grading Machine to a fruit grower and exporter in India, for weight-based grading of fresh pineapple at their packing facility to meet the specification requirements of export markets.
Client's Core Needs
The client is a fruit grower and exporter based in India, serving overseas markets. Prior to adopting our equipment, the client faced the following challenges:
1. Insufficient Accuracy in Manual Grading
The client previously relied on visual inspection for fruit grading. Different workers applied inconsistent standards, resulting in mixed sizes within the same batch—making it difficult to meet the strict size specification requirements of export markets.
2. Strict Weight Specifications in Export Markets
Overseas markets have clear weight range requirements for different fruit grades. The client needed equipment capable of precise weight-based grading to ensure every batch met the entry standards of target markets.
3. Controlled Equipment Investment
As a medium-scale packing house, the client needed to achieve grading automation within a reasonable investment range. Large-scale fully automatic grading lines involved excessive investment and complex maintenance, which did not align with the client's cost expectations.
Equipment Solution
To address the client's needs, we provided the Manual Weight Grader.
How It Works
The machine uses weight sensor technology for precise grading. Workers place fruits one by one onto the conveying cups. As the cups pass over the built-in weight sensor, the sensor measures the weight of each fruit in real time. The system then automatically directs each fruit to the corresponding outlet based on preset weight ranges.

Key Advantages
· ±2g High-Precision Grading: Real-time weight sensor measurement delivers accuracy far beyond manual visual inspection, ensuring consistent fruit sizing
· Compact Footprint, Space-Saving: Occupying only approx. 9.6m² (7020×1370mm), the streamlined linear layout fits comfortably in the limited floor space of small to medium-scale packing houses—no major facility modifications required
· VFD Speed Control, Flexible Throughput: Equipped with a Schneider frequency converter, operating speed adjusts flexibly to match feed rate
· Multi-Fruit Compatibility: Suitable for mangoes, grapefruits, apples, oranges, pears, dragon fruit and more—the client can continue using the equipment if they expand to other fruit varieties in the future
· Low Learning Curve, Easy Maintenance: Intuitive control panel allows workers to operate after minimal training; well-designed structure simplifies daily cleaning and upkeep
Implementation
The equipment was manufactured on schedule and delivered to the client's facility in India. Our company provided detailed installation guidance and operating instructions to assist the client with equipment installation and commissioning.
The equipment is now operational, helping the client upgrade from manual visual grading to automated weight-based grading.
Project Value
· Enhanced Export Compliance: Precise grading ensures consistent sizing across every batch, meeting overseas market weight specifications and reducing the risk of failed inspections
· Significant Labor Savings: One machine replaces 6–8 manual graders, delivering a short payback period
· Optimized Facility Space: Compact footprint eliminates the need for costly plant expansion, saving additional capital investment
· High Equipment Utilization: Multi-fruit versatility means no need for repurchase when expanding to new fruit categories—further shortening the ROI cycle per machine
The successful delivery of this project validates the reliability and practicality of our Manual Weight Grader in export fruit grading applications.
