What causes clumping when adding powder? Design points for preventing and addressing poor dispersion.

澁谷工業 澁谷工業
In dispersion processes, the occurrence of agglomerates (clumps) during powder addition, which cannot be resolved in subsequent dispersion stages, is a common issue in many settings. The cause of this is that the powder does not wet uniformly in the liquid, leading to the formation of localized high-concentration areas. These agglomerates are also referred to as "fisheyes," and due to their internal unwetted structure, they are difficult to break apart. Once an agglomerate forms during powder addition, liquid has difficulty penetrating its interior, resulting in only the outer layer being wetted, which makes it hard for the internal particles to be disintegrated. Additionally, depending on the addition position and speed, the powder may float on the liquid surface or remain stagnant without following the flow within the equipment, promoting the formation of agglomerates. Particularly under conditions of high viscosity or high solid content, the low fluidity makes it challenging to achieve uniformity in the initial dispersion stage, leading to a higher likelihood of agglomerates remaining. Such agglomerates may not be completely resolved even with strong shear in subsequent processes, causing variations in the quality of the final product and introducing foreign substances. To prevent the formation of agglomerates, it is crucial to improve wettability during powder addition, ensure appropriate addition positions and flow design, and optimize the initial dispersion. By performing shear and mixing simultaneously right after addition, as in inline powder addition and simultaneous dispersion, it is possible to suppress the formation of agglomerates and achieve stable dispersion quality.

This is the powder input and dispersion integrated system to prevent agglomeration.
The occurrence of lumps during powder input significantly affects the subsequent dispersion quality. Our solid-liquid mixing system achieves a uniform dispersion state from the initial stage by performing shearing and dispersion simultaneously with the powder input. We offer a stable process design that accommodates high viscosity and high solid content conditions while minimizing the formation of lumps.

Protein dispersion test service

Resolve issues of not dissolving and clumping in advance. Test the dispersibility of the protein.

The quality of protein products is greatly influenced by their dispersion state. In particular, powdered protein often faces challenges such as clumping during dissolution in water or solvents, uneven dispersion, and poor mouthfeel. Additionally, changes in formulation or raw materials can alter viscosity and dispersibility, leading to cases where there are no issues during prototyping but quality becomes unstable during mass production. This service conducts dispersion tests tailored to raw material characteristics and formulation conditions, verifying the suppression of clumping, improvement of dispersibility, and enhancement of mouthfeel. Furthermore, through process design aimed at scaling up from the lab to small machines and mass production equipment, we establish reproducible manufacturing conditions. We can support evaluations from the prototyping stage to pre-mass production verification.

Protein dispersion and mixing system for beverage manufacturing (solid-liquid mixing)

Suppressing sedimentation and evenly dispersing the protein.

In the manufacturing of protein drinks, issues such as "clumping," "residue," and "sedimentation/separation" are not merely due to insufficient stirring, but are caused by factors such as powder input conditions, wettability, and the design of mixing and dispersion processes. Particularly during high-concentration formulations or the addition of functional materials, variations in quality and reduced reproducibility become problematic. Shibuya Kogyo's solid-liquid mixing and dispersion system is designed as an integrated solution from powder supply to mixing, dispersion, and formulation, enhancing the solubility and dispersion stability of proteins. Through process optimization tailored to material properties and viscosity conditions, it achieves clump suppression, uniform dispersion, and prevention of sedimentation. We provide consistent support from the research and development stage to mass production equipment, ensuring quality reproducibility during scale-up. This contributes to stable production and quality improvement in food applications. Please consult us about your current challenges.

Dispersion machine (solid-liquid mixing dispersion system) slurry dispersion line

Dispersion is not determined by the equipment. It is determined by the process design of the solid-liquid mixing dispersion system.

The occurrence of "agglomeration," "cohesion," and "viscosity increase" in dispersion processes is caused not by the equipment but by the design of the process. Poor wetting during powder input and unsuitable dispersion conditions lead to quality variations and poor redispersion, significantly compromising stability during mass production. Additionally, during scale-up, it is often impossible to reproduce the same conditions, resulting in unexpected troubles. Furthermore, every time there is a change in materials or formulations, new conditions must be established, increasing the burden of development and mass production. Shibuya Kogyo's solid-liquid mixing and dispersion system is designed to provide a consistent process from powder supply to dispersion, formulation, and CIP cleaning. By optimizing the entire process, including material properties, input conditions, and fluid design, we stabilize dispersion quality and reproducibility. Moreover, optimization across the entire line contributes to reducing losses between processes and lowering equipment load. It is not just a dispersion machine but a dispersion system that governs the entire process. By building quality from the design stage, we achieve shorter startup times and improved yields. We also provide consistent support from equipment selection to startup, reducing the burden on the site. We propose the optimal dispersion process tailored to your materials and process conditions. Please consult us about your current challenges. We support you from initial considerations to mass production startup.

CNT disperser for continuous dispersion of nanomaterials.

Supports CNT aggregation prevention and uniform dispersion. Assists in stabilizing the quality of conductive material slurry through continuous processing.

This is a solid-liquid mixing system for conductive material slurries utilizing CNT dispersers. Carbon nanotubes (CNTs) tend to agglomerate easily, and their conductivity and slurry quality are significantly affected by dispersion conditions. This system addresses CNT agglomeration through high-shear dispersion and stabilizes quality through uniform dispersion. Additionally, inline continuous processing reduces dispersion variability, improves reproducibility, and stabilizes production. It also accommodates process design that includes powder supply, dispersion, defoaming, and transfer, allowing for system proposals that combine inline dispersers, batch dispersers, static mixers, etc., according to material properties and viscosity conditions. It is utilized for improving process challenges in applications involving nano materials such as CNT conductive material slurries, battery materials, electronic materials, and high-performance materials. It is capable of supporting everything from lab tests to scale-up and mass production line construction.

Hyper CLT flooring panel

Reasons for Being Chosen for Public Works | NETIS Registered "Hyper CLT Paving Slab"

  • NEW
  • PRODUCT

One of the major strengths of the Hyper CLT sheet is that it is a technology registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS. The NETIS registration number is **"TH-250021-A."** In public works, it is important to explain to the client "why we are introducing it" and "what effects we expect" when adopting new materials. If it is a NETIS registered technology, it becomes easier to connect it to proposals for the utilization of new technologies and creative ideas. The Hyper CLT sheet is a civil engineering sheet that utilizes wood CLT. It is lightweight and easy to install and remove, and it has characteristics unique to wood, such as reducing summer heat reflection and noise, and fixing CO2. It is important to be able to propose it not just as "wooden sheets," but as a civil engineering technology registered with NETIS. The Hyper CLT sheet, which combines wood, NETIS, civil engineering, and CLT, is a new temporary material that makes it easier to clearly demonstrate the reasons for its introduction in public works.
