Aishin Industrial (Thailand) presents an innovative discharge system, the “precision weighing system (AI Dosing System)”, for the efficient and accurate feeding of powder and granular materials. In this article, we will introduce the features of the product in detail.

Weighing error within +/-1g range! High precision weighing and feeding of powders and granules

The “AI Dosing System” is a precision weighing system designed for efficient and accurate feeding of powders and granules. Unlike conventional rotation mechanisms, this system uses a cut-gate system to ensure stable feeding without being affected by the shape or physical properties of the material. It reduces the risk of damage to the shape of powders and granules, improves the stability of the manufacturing process, and enables accurate weighing within a range of +/-1 gram.

【Main features of the precision weighing systemำ】
■ Self-weight drop prevents breakage of granules
Unlike the common rotary system, cut-gate's self-weight drop system is not affected by material characteristics and reduces the risk of damaging the shape of powder or granular materials.

■ High feeding accuracy
While the weighing error of general powder and granular measuring instruments is about 1%, this product can accurately weigh within the range of +/-1 g, regardless of the number of measurements or the characteristics of the material. Very small weighing errors ensure product quality. There is almost no residual weight after weighing is completed.

■ Wide range of adjustment
The wide adjustment range allows flexible adjustment of supply volume, making it adaptable to a variety of production lines.

■ Multifunctionality
A single machine can register and measure multiple substances, thus improving production efficiency. In addition, the control system makes it easy to correct or modify the emission volume. The main body is made of stainless steel to prevent raw materials from contacting the gasket.

■ Simple structure and easy maintenance
The simple structure allows for easy periodic disassembly cleaning and replacement of parts about once a year, minimizing production line downtime.

【Weighing control】
■Supports both additive and subtractive weighing
■Parameters can be set for each material for optimum weighing

【Main applications】
■Food, pharmaceuticals, fine chemicals, and secondary battery materials
■Wearable materials, difficult-to-discharge raw materials, and high-capacity filling

Powder and granule precision weighing system lineup selectable according to application

The precision weighing system uses a dosing valve that enables fine feeding and can handle a variety of material characteristics from fine powders to lumps, and is available in H type (cut-gate type) and V type (pendulum type).

■ AI Dosing System-H (cut-gate type)

A special valve in the shape of an egg cutter moves horizontally and repeatedly to control the amount of material discharged. The valve opening can be adjusted in increments of 0.1mm, and the discharge rate can be set continuously at a ratio of 1:200.

▲ Only 10 parts, simple structure and high cleanability

■ AI Dosing System-V (pendulum type)

The fan-shaped valve body moves like a pendulum to control the discharge. The valve opening is adjustable in increments of 0.1 mm, and the discharge volume can be set continuously at a ratio of 1:200.

▲ Only 7 parts, simple structure and high cleanability

Aisin Industrial's powder and granule precision weighing systems have been implemented at various manufacturing sites throughout Japan, mainly in fields such as the supply of raw materials for Chinese medicines and the processing of carbon powder and vinyl chloride powder. In cooperation with factories in Japan, it is possible to conduct sample tests of products prior to installation, and through visualization of numerical values, it is possible to realize designs that meet customer needs.
