Our Tailored Full-Auto Solution

Core Solution Units

1. ·20-Head 1.6L Multihead Weigher

   The core weighing unit of the whole line, specially optimized for fragile puffed food. It adopts a dual 10-head independent working mode, the 20-head weigher is divided into two independent weighing zones (Zone A and Zone B), each equipped with 10 sets of high-precision weighing units, to realize synchronous quantitative weighing of two channels. The outlet is equipped with a dual-chamber temporary storage hopper (Chamber A and Chamber B), which temporarily stores the weighed materials respectively, perfectly matching the beat of the dual-station filling machine, ensuring high weighing accuracy and no damage to puffed food.
2. ·Stable Integrated Supporting Platform

   Provides a solid anti-vibration support base for the whole production line, integrates the central electrical control system, realizes unified coordination and intelligent signal linkage of all equipment units, ensuring stable and synchronous operation of the whole line. The compact integrated design saves workshop floor space, and is convenient for daily operation and maintenance.
3. ·Z-Type Elevator

   Closed automatic feeding equipment, specially designed for fragile puffed food. It adopts a gentle lifting structure to avoid product breakage during the lifting process, and the closed design prevents dust, moisture and secondary contamination. It stably lifts the puffed food from the bottom hopper to the upper feed hopper of the multihead weigher, realizing continuous and stable material supply.
4. ·Horizontal Metal Detector

   Installed at the front end of the feeding line, it adopts high-sensitivity horizontal detection technology to accurately detect metal foreign bodies mixed in puffed food in real time. Once metal foreign bodies are detected, the system will send an alarm prompt, and the unqualified products can be manually removed in time, completely eliminating food safety risks from the source.
5. ·Dual-Station Filling Machine

   The core filling host of the whole line, exclusively designed for paper tube/box packaging of puffed food. It adopts dual-station synchronous filling design, which can simultaneously complete the filling of two paper tubes/boxes, greatly improving production efficiency. Equipped with an anti-spilling guide structure, it accurately docks with the paper tube mouth, ensures that the weighed puffed food is completely filled into the container without spilling, and perfectly matches the temporary storage hopper of the multihead weigher to realize synchronous filling beat.
6. ·CW220 Check Weigher

   High-precision online weight re-inspection equipment, installed at the back end of the filling process. It conducts 100% full inspection of the net weight of each filled paper tube/box in real time, automatically identifies and alarms unqualified products with overweight or underweight, ensures that each finished product fully complies with international net content regulations, and perfects the whole-process quality control system.

Standardized Automated Operation Flow

1. ·Front-End Metal Detection & Feeding: Puffed food products enter the hopper of the Z-type elevator after passing through the horizontal metal detector. The metal detector detects metal foreign bodies in real time, and the products with detected metal foreign bodies are manually removed by the operator to ensure the safety of raw materials.

2. ·Closed Gentle Lifting & Feeding: The Z-type elevator lifts the qualified puffed food to the upper feed hopper of the 20-head multihead weigher in a closed, gentle and non-damaging manner, realizing continuous and stable material supply for the weighing unit.

3. ·Dual-Zone Quantitative Weighing & Temporary Storage: The 20-head multihead weigher operates in dual 10-head working mode, divided into two independent weighing zones (Zone A and Zone B), each with 10 sets of weighing units, which complete high-precision quantitative weighing of puffed food in Zone A and Zone B respectively according to the preset target weight. The outlet of the multihead weigher is equipped with a dual-chamber hopper (divided into Chamber A and Chamber B). After the weighing in Zone A and Zone B is completed, the materials are discharged into the corresponding Chamber A and Chamber B of the hopper for temporary storage. At the same time, the empty paper tubes/boxes are transported from the sorting table to the filling position of the dual-station filling machine, ready for filling.

4. ·Dual-Station Synchronous Filling: The dual-station filling machine receives the signal from the multihead weigher, and the dual-chamber hopper releases the weighed materials into the corresponding paper tubes/boxes synchronously, completing the spill-free filling process accurately.

5. ·Online Weight Re-inspection: After filling, the finished paper tubes/boxes are automatically transported to the CW220 check weigher for 100% online net weight inspection. Unqualified products with overweight or underweight will be automatically identified and alarmed, and only qualified finished products will flow into the subsequent packaging process.

Final Achievable Effects & Business Benefits

1. ·Ultra-low Product Breakage Rate & High Weighing Accuracy
