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.

Metal Crack Repair: MS Method for Repairing Cracks and Fractures in Machinery Equipment

  • NEW
  • PRODUCT

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
