The grading scale is widely used in industries such as food, aquatic products, fruits and vegetables, poultry and meat, Chinese medicinal materials, daily chemicals, pharmaceuticals, and chemicals.

Large-sized Box Type Weight Sorting Machine

Suitable for weighing and sorting products such as white chicken, white duck, whole chicken, whole duck, large goose, pigeon, hairy crab, yellow croaker, and other fields that require weight sorting and grouping.


The grading scale is a device used to weigh and grade products. It can weigh products of different weights during continuous operation, automatically classify and combine them according to the set weight level, and can also statistically store product data. It has fully automated control, integrated weighing and grading, replaces traditional manual weighing and sorting, and automatically weighs and sorts at multiple levels to save labor and improve efficiency. It uses dynamic weighing anti-interference technology, making weighing data more reliable and achieving precision and standardization. It is a key equipment for online weight standardization testing of products, helping enterprises realize process management and improve product quality. It has the characteristics of compact structure, beautiful appearance, accurate weighing, fast grading speed, durability, and easy cleaning. It is suitable for the food, aquatic products, fruits and vegetables, poultry meat, medicinal materials, daily chemical, pharmaceutical, and chemical industries.

Working principle:

The grading scale consists of a frame, a material box, a control system, a weighing sensor, a conveying system, and a sorting mechanism. The product to be graded is placed into the material box for transportation. During transportation, the weighing sensor completes the collection of weight signals and sends the weight signals to the control system for processing. The completed products are transported out of the weighing area by the conveying mechanism and transported to the sorting mechanism. The system compares the weight range with the preset range and automatically classifies and groups the products. It can also collect and store product data, and can work continuously with good repeatability.


Application range:

The grading scale is widely used in industries such as food, aquatic products, fruits and vegetables, poultry and meat, Chinese medicinal materials, daily chemicals, pharmaceuticals, and chemicals.
