I. Product Overview
Integrated gold assay and re-assay machine Digital metal detector and High-precision weight recheck scale Featuring two core modules and an integrated 304 stainless steel frame, this system enables a single production line to simultaneously perform metal foreign‑object detection and weight‑check inspections—two critical quality‑control steps—eliminating the need for separate, stand‑alone equipment and its segmented installation. This saves floor space, reduces manual interfacing along the line, and seamlessly integrates into automated end‑of‑line inspection lines for food, pharmaceuticals, pet food, and daily‑use chemical packaging. At the front of the system, the YJ‑DTC three‑coil, all‑digital metal detector serves as the primary sensor; in the middle, a high‑precision weighing platform ensures accurate mass verification; and at the rear, a flip‑plate‑type automatic reject mechanism handles defective products. Together, this single unit addresses two major quality‑control challenges—metal contamination and underfilling—while meeting HACCP, GMP, and FDA export‑inspection standards. It is a one‑stop quality‑assurance solution for fully automated packaging lines.
II. Comprehensive Core Selling Points of the Entire Device
- Dual inspection with a single device, reducing costs and saving space. A single device simultaneously performs metal detection. + Weight re‑inspection, compared with procuring separate gold‑detection machines and checkweighers, reduces equipment procurement costs, minimizes the footprint of the production line, eliminates manual transfer steps between the two stages of equipment, and enhances the overall automation level of the entire production line.
- Dual quality-control checks prevent double losses. It both intercepts and processes metal contaminants to prevent supermarket recalls and customer claims, and eliminates issues such as insufficient packaging materials, underfilling, and missing components, thereby avoiding complaints of short weight or quantity and regulatory penalties—ensuring that a single system safeguards against two major quality‑control risks.
- Fully sanitary-grade compatible, meeting export factory inspection requirements. Whole machine 304 Stainless steel, highly waterproof protection, compliant with HACCP/GMP/FDA Standardization: Foreign‑object detection data and weight‑nonconformance data are automatically stored in a dual‑system architecture, enabling third‑party audits and customs spot checks to access complete quality‑inspection records.
- Synchronous variable-frequency interlock, compatible with high-speed production lines. The three conveyor belts for metal detection, weighing, and rejection are equipped with synchronized variable-frequency drives, achieving a maximum… 40 m/min High-speed inspection ensures smooth operation, eliminating product backlog and missed defects, and is compatible with fully automated high-speed packaging, filling, and boxing lines.
- Stable and durable under all operating conditions. The thickened stainless steel frame has a high self-weight, providing excellent shock absorption and resistance to motor vibrations in the workshop; it is well-suited to the working environment. - 10℃~50℃ Cold storage, high-temperature processing, and high-humidity sauce-processing workshops, 24 Low hourly continuous production failure rate and simple maintenance.
III. Mainstream Applicable Industries & Inspection Workstations
Applicable Industries
- Food Industry (Core Scenarios) Meat products, frozen dough-based foods, frozen seafood, snack foods, baked goods, sauces and seasonings, and bagged grain and oil products; with metal fragment screening also conducted. + Material shortage and excessive weight.
- Pharmaceutical and Healthcare Products Industry Capsules, tablets, traditional Chinese medicine powders, and ointments—packaged finished products; screening out metallic debris from molds and inspecting tablets and powders for underfilling to ensure compliance. GMP Cleanroom production requirements.
- Pet food industry Bagged cat and dog food, canned food, and bulk freeze-dried feed; intercepts metal contaminants in grinders and detects underfilling or missing bags.
- Daily chemical and maternal & infant industry Packaging for facial masks, wet wipes, diapers, and personal care powders; inspection for metal fragments in nonwoven fabrics and verification that packaging does not omit any contents.
- Foreign trade export processing factory Complete export‑ready packaging for all product categories; a single piece of equipment simultaneously meets overseas customers’ requirements for metal detection and weight‑based sampling inspections.
Standard installation workstation
At the final inspection station, after product packaging is completed, the line interfaces with the downstream packaging and coding machines, serving as the last quality‑control checkpoint before the finished goods leave the facility.
- Dual inspection with a single device, reducing costs and saving space. A single device simultaneously performs metal detection. + Weight re‑inspection, compared with procuring separate gold‑detection machines and checkweighers, reduces equipment procurement costs, minimizes the footprint of the production line, eliminates manual transfer steps between the two stages of equipment, and enhances the overall automation level of the entire production line.
