What are the causes of dispersion troubles? An explanation of the reasons for aggregation, sedimentation, and variation, as well as design points to reconsider in the dispersion process.

澁谷工業 澁谷工業
In dispersion engineering, issues such as unresolved agglomeration, sedimentation, and unstable particle size distribution occur frequently at many sites. These problems are caused not only by the performance of the equipment but also by inconsistencies in particle characteristics, dispersion conditions, and process design. For example, when there is insufficient dispersion energy, particles do not break down to primary particles, and agglomeration remains. Additionally, if the shear conditions or flow state are not appropriate, uniform dispersion cannot be achieved, leading to sedimentation and variations in quality. Particularly in high-viscosity systems or high solid content slurries, even slight differences in conditions can significantly impact the results. Furthermore, in batch processing, variations in mixing uniformity and residence time make it difficult to ensure reproducibility. To resolve these dispersion issues, it is important to optimize the entire process, including particle characteristics, dispersion energy, and flow design, rather than simply changing the equipment. By maintaining consistent conditions, as in inline continuous processing, stable dispersion quality and reproducibility can be achieved.
Poor dispersion causes particles to remain agglomerated, leading to sedimentation and variations in quality.

Here is the approach to process design and engineering to prevent dispersion troubles.
Dispersion troubles arise not only from the equipment itself but also from multiple factors such as particle characteristics, dispersion conditions, and flow design. Our company offers process engineering that focuses on inline continuous processing, optimizing dispersion energy and shear conditions, and considering reproducibility during scale-up. We will introduce specific design points to achieve stable dispersion quality.

CNT water dispersion liquid manufacturing system (inline continuous type, dispersion stabilization)

Inline continuous process that stabilizes CNT dispersion without disrupting its state.

In the production of CNT water dispersion, it is important not only to break down agglomerates but also to maintain a dispersed state. CNTs tend to agglomerate strongly at the nanoscale, and even after dispersion, re-agglomeration can occur, making stable quality assurance a challenge. This system consistently controls the process from dispersion to stabilization through inline continuous operation. It maintains a uniform dispersion state while suppressing excessive shear, preventing re-agglomeration. It accommodates water-based and low to medium viscosity conditions, contributing to the stabilization of CNT dispersion quality and improving reproducibility in mass production processes. Furthermore, by optimizing dispersion conditions and residence time, it is possible to suppress variations in the dispersion state and continuously ensure stable quality. It also supports consistent scale-up design from the lab to mass production, aiding in the stable manufacturing of CNT dispersion.

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.

Wooden CLT flooring at summer construction sites | Hyper CLT flooring

  • NEW
  • PRODUCT

In civil engineering sites during extreme heat, the surface temperature of the ground plates and the heat reflection significantly affect the working environment. In particular, steel plates tend to retain heat when exposed to sunlight, posing challenges for workers' heatstroke prevention and safety management. Hyper CLT ground plates are civil engineering materials utilizing wood CLT. As wooden ground plates, they can be used for temporary roads, access routes, heavy machinery work yards, material storage areas, and pedestrian pathways, making them a versatile alternative to steel plates in various civil engineering sites. In actual sites, there are cases where the surface temperature differs by about 20 degrees compared to steel plates, making them effective as a solution for heat prevention and reflection suppression. The 5×10 plate weighs approximately 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce the burden of transportation, installation, and removal. They are materials that easily promote noise reduction, CO2 fixation, and environmental consideration unique to wood. Registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A," they can also be utilized for creative ideas and safety measures in public works. They are recommended for companies looking to reassess the summer site environment. We also accept inquiries for consultations and requests for materials tailored to site conditions. We can propose solutions for temporary plans during summer for both public and private civil engineering projects. Please feel free to consult with us.

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 often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks 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.
