[Technical Column Update] How to Eliminate Rat Holes in Flour and Matcha? Testing the Effectiveness of Aeration Hoppers.

MONOVATE(旧:日東金属工業) MONOVATE(旧:日東金属工業) 八潮工場
Powders behave very differently depending on their properties and the environment in which they are handled, making them very difficult to manage. Our company receives daily inquiries regarding the handling of powders, and among them, a common issue reported is that "blockages such as bridges and rat holes occur, preventing sufficient quantities from being supplied to the next process." To address these challenges, our company offers an "aeration hopper" in our product lineup, and to ensure that customers can confidently choose our products, we conducted experiments to demonstrate its effectiveness.

Resolve hopper powder clogging | Aeration hopper

An accessory that eliminates powder blockages such as in rat hole bridges and promotes smooth discharge. It is used by attaching it to the hopper outlet.

【Smooth discharge by moving powder like a liquid, reducing labor and raw material loss】 It is used by connecting air. Air flows into the hopper, promoting the discharge by fluidizing the powder. 【Structure with excellent cleaning properties to prevent cross-contamination】 The inner hopper has fine holes that allow air to be drawn in. The interior of the holes has a structure close to straight, making it easier to clean even when powder gets inside compared to multiple layers of meshes with different roughness. This reduces the risk of contamination in cases of producing multiple types on the same line or in the pharmaceutical industry, where high hygiene levels are required. 【Would you like to experience powder fluidization?】 You can experience powder fluidization using the aeration hopper at "INTERPHEX OSAKA," one of the largest pharmaceutical and cosmetic manufacturing technology exhibitions in Kansai! Please visit our booth. Event dates: February 25-27, 2025 Venue: Intex Osaka Booth location: Hall 5, 6-31 For visitor registration and other exhibited products, click here: https://www.monovate.co.jp/blog/blog/bipj-o2025/

イプロスカスタムホッパー.jpg

Stainless Steel Hopper Custom Catalog

A stainless steel hopper that can be customized with up to 7 parts.

◆We solve these problems with stainless steel hoppers! "Poor usability," "Size doesn't fit," "Contents don't flow out smoothly." ◆Here’s what sets our stainless steel hoppers apart "You can specify the height." You can specify the height of the hopper body and the leg height in 10mm increments. This allows you to choose according to the installation location and work content, leading to increased work efficiency. "You can choose the discharge outlet." You can select fittings (such as unions, sockets, nipples, flanges) that match the connection destination. This prevents issues where the "type of fitting differs" or the "size of fitting differs" from the connection destination. "You can choose the hopper angle." You can choose the hopper angle from 45° (eccentric), 60°, or 90°. The hopper angle can affect the flowability of the contents, and selecting the hopper angle according to the contents can lead to improved workability, time savings, and stable quality. For more details, please refer to the PDF.

THT-G_01.jpg

A stainless steel hopper that is resistant to powder adhesion and less prone to bridging.

A feeding hopper with a surface treatment that allows powder to flow smoothly, ideal for feeding filling machines and large containers.

Powder Adhesion Prevention Input Hopper [THT-G] - The inner surface of the hopper has been treated with Gemini processing to prevent powder adhesion. - Since the surface is directly processed, there is no concern about the surface peeling off, unlike coatings. - It has good slip properties, making it less likely to experience bridging, allowing for smooth discharge. - The discharge port has a helix design, making installation, removal, and cleaning easy.

Lathe Module "TURNING"

Lathe module "TRUNING" scheduled for release in February 2026.

  • NEW
  • PRODUCT

From turning processing to milling processing—responding to process integration with composite machining centers C&G Systems Co., Ltd. has released the lathe module "TURNING," which realizes the "true process integration" required in the era of composite machining centers. By covering 2D and 3D milling, wire electrical discharge machining, and turning processing, "EXCESS-HYBRID II / Parts CAM" has evolved into an ALL-IN-ONE CAM system that transcends the boundaries of processing fields. The lathe module "TURNING" was developed against the backdrop of voices from the field, where the advancement of high functionality and integration of NC machine tools has led to continued reliance on interactive input and manual programming, resulting in increased man-hours, occurrence of errors, and a shortage of skilled technicians. While composite machining centers have the significant advantage of completing both turning and milling in one machine, the diversification and complexity of processed shapes have made programming advanced and intricate, necessitating measures against interference risks and efficient process design. "TURNING" achieves a reduction in programming time and stable quality reproduction, maximizing the performance of composite machining centers.
