Description
This dynamic conveyor checkweigher is an inline automatic weight inspection device specially customized for food production packaging lines. It performs real-time continuous weight detection of flowing packaged products, automatically separating underweight, overweight and qualified goods to realize full-process quality control.
Adopting SUS304 all-stainless steel hygienic structure, high-precision weighing sensor and intelligent touch screen control system, the machine complies with global food safety standards (FDA, CE, RoHS). It can be seamlessly connected with filling, packaging, metal detector and cartoning equipment, widely applied in coffee, snack, frozen food, dairy, seasoning and other food processing factories.

4. Working Principle
- Packaged food products flow into the weighing conveyor through front production line;
- Infrared sensor detects incoming goods and triggers the weighing module;
- High-precision sensor captures real-time product weight and transmits data to touch screen controller;
-
System compares actual weight with preset upper/lower weight limit values:
- Weight within tolerance: product passes normally to next process;
- Weight lighter / heavier than set range: rejection device automatically pushes out unqualified goods, with sound-light alarm notification;
- All weighing and rejection data are automatically stored for later export and quality analysis.
5. Wide Application Industries
- Coffee Industry: Packaged coffee beans, ground coffee, coffee capsule weight inspection
- Snack & Confectionery: Potato chips, biscuits, candy, nut small bag weight checking
- Frozen Food: Frozen dumplings, steak, quick-frozen prepared meals
- Dairy & Beverage: Milk powder cans, yogurt boxes, beverage bottles
- Seasoning & Condiment: Sauce packets, spice bags, edible oil bottles
- Pet Food: Small bag and large bag pet feed weight detection
- Pharmaceutical & Cosmetic: Small medicine boxes, cream cosmetic packaging
