Multi Level Weight Sorting Equipment

The fresh produce, fruits and vegetables, aquatic and seafood, and poultry processing industries have long been plagued by core pain points: low manual grading efficiency, inconsistent weight standards, difficulty in achieving product premiums, high labor costs, and excessive fresh product loss. For products such as Chinese mitten crabs, crayfish, premium fruits, and cut poultry, weight grading directly determines product pricing, brand reputation, and profit margins.

To address this critical industry need, Jiangsu Jutian Weighing Equipment Co., Ltd., with over 20 years of deep expertise in the weighing industry, an in-house 919 R&D Center and intelligent production base, has developed the J-SKY Multi Level Weight Sorting Equipment. Deeply customized for multi-stage weight grading scenarios, it delivers fully automatic, precise product grading by weight range, serving as core equipment for fresh food and agricultural product processing enterprises to achieve standardized production, increase product premiums, and reduce labor costs.

Product Advantages

Core Value: Beyond Grading, Boosting Product Profitability

Unlike traditional checkweighers focused on non-conforming product rejection, the core value of the J-SKY Multi Level Weight Sorting Equipment is to solve three key profitability pain points in the fresh food and food processing industries:

Eliminating inconsistent manual grading standards

Manual weighing has large errors, resulting in uneven specifications for products in the same batch, which undermines end-market pricing and brand reputation. This machine delivers 100% consistent grading standards with zero mis-sorting or missed sorting.

Solving low grading efficiency

Manual grading has extremely low hourly output, failing to keep up with large-scale mass production and peak season order demands. The machine reaches a maximum sorting speed of 200 pieces per minute, far exceeding manual efficiency.

Unlocking product premium potential

Precise multi-stage weight grading enables tiered pricing for products in the same batch based on weight, greatly expanding the premium space for high-grade products. It also reduces fresh product loss and cross-contamination risks caused by excessive manual handling.

Equipment Structure & Food-Grade Exclusive Design

The J-SKY Multi Level Weight Sorting Equipment is a proven, mature product with long-term market validation and outstanding customer feedback. It features a modular quick-release structure, consisting of four core units: infeed buffer section, high-precision weighing section, multi-channel grading execution section, and intelligent control cabinet.

The main body is standard equipped with a food-grade 304 stainless steel frame (316L corrosion-resistant stainless steel optional), paired with a food-grade PU conveyor belt. The whole machine has no hygienic dead corners, and conveying components can be quickly disassembled and cleaned without tools, fully complying with high hygiene standards in the food industry and eliminating cross-contamination of fresh products.

All core components are sourced from well-known industry brands, with built-in industrial ultra-high-precision weighing sensors and 24V brushless drive motors, paired with Jutian’s self-developed intelligent grading control system. It delivers stable operation, low failure rates, and extremely low maintenance costs, suitable for 7×24-hour continuous large-scale production. It supports multiple sorting methods including air blowing, pusher, flap, and diversion, which can be flexibly selected according to product characteristics.

Core Performance & Differentiated Advantages

Multi-Stage Flexible Grading for Full Scenario Adaptation

The machine supports 1–5 weight grading stages as standard, expandable to 8 stages according to customer needs. Users can freely preset the upper and lower weight limits for each grade, and the system automatically and accurately diverts products to the corresponding channels by weight range without manual intervention.Compared with traditional single-stage rejection equipment, this machine completes simultaneous grading of multi-specification products in one go, eliminating the need for repeated sorting and greatly shortening the production process.

Ultra-High Precision & High-Speed Sorting, Balancing Efficiency and Accuracy

Weighing range: 5g–5kg

Minimum detection accuracy: ±0.1g

Maximum sorting speed: 200 pieces per minute (1800 pieces per hour)

Grading accuracy rate: close to 100%

Even for small, fragile products such as crayfish and small berries, it achieves damage-free and precise grading, completely eliminating mis-sorting and missed sorting common in manual grading.

Food-Grade Waterproof Design for Fresh Processing Scenarios

The whole machine adopts industrial-grade waterproof and dustproof design, with a standard IP54 protection rating and optional IP65 high protection rating, supporting high-pressure washing of the entire unit. It perfectly adapts to the high humidity and frequent cleaning requirements of fresh food processing workshops. The quick-release modular design enables dead-corner-free cleaning, strictly complying with safety production specifications for the food and pharmaceutical industries.

Intelligent Digital Management for Full-Process Traceability

Equipped with a 10-inch industrial touch screen with Chinese/English bilingual operation interface, it real-time counts the quantity and weight data of products in each grading stage, automatically generates production reports, and supports USB data export.Abundant reserved industrial interfaces including Ethernet port, RS232/485 enable seamless connection with inkjet printers, barcode scanners, PLC, MES and other production equipment and management systems, realizing full automation of product grading, coding, and traceability to meet the digital production needs of large-scale enterprises.

Full-Dimensional Customization for Exclusive Solutions

Full non-standard customization is supported, including weighing platform size, number of grading stages, sorting method, protection rating, and software functions. We provide complete OEM, ODM, OBM and software secondary development services, with a stable monthly production capacity of 50 units. Exclusive weighing and grading solutions can be tailored to your product characteristics, workshop layout, and production needs.
