Retinol, vitamin C, and fragrance components used in cosmetics are prone to degradation due to the effects of heat, light, and oxygen. This technology contributes to the protection of these ingredients and enhances stability in products through microencapsulation using cyclodextrin. Additionally, the sustained release function allows for the continuous release of active ingredients and fragrances. It also improves the dispersibility of lipophilic components and enables powder formulation, achieving high added value for skincare and haircare products.

The roller compactor (https://www.nc-ind.com/equipment/000019.php) can compact powder into granules by applying a maximum compression pressure of 5t/cm. The processes of adding a binder to the powder, dewatering, and drying can be combined and shortened into one step. ◎ Advantages of compact granulation ◎ "Easy to handle" → Reduces dust generation and scattering of powders → Improves measurability, transportability, and volume reduction "Retains original properties" → Can compact granulate using only powder without a binder ■ Recommended for such products 【Battery materials (cathode and anode materials)】 　◎ Reduces the intergranular void ratio that can hinder the sintering process 　　※ Sintering furnaces are also available! 　◎ Reduces costs associated with shaping using binder addition 【Resins, powder coatings, toner fine powders, cosmetic ingredients, resin additives, fertilizers, animal feed】 　◎ Increases bulk density, improving mixing stability and uniformity with other raw materials 　※ Abundant mixing machines 　◎ Prevents thermal degradation 【Additives, solid catalysts for industrial use】 　◎ Prevents modification due to binders 　◎ Improves solubility and dispersibility in the next process, prevents segregation 　◎ Enhances storage stability of granulated products 　◎ Pre-treatment before extrusion and tablet pressing = particle size adjustment

Battery materials for EVs, cosmetic ingredients including zinc oxide and titanium oxide, and fine ceramics materials for semiconductors and electronics are increasingly required to be "micronized" on a daily basis. The market size is also growing, and there are many requests from customers who want to achieve "powdering and micronization" using spray drying for research and development aimed at performance improvement and mass production. In our contract manufacturing, after spray-drying, we have analytical equipment that can quickly analyze the "particle shape, particle size distribution, moisture content, and bulk density" of the powder that customers want to know as soon as possible, on the same day. **Example of analysis items for powder after spray drying:** - **Particle shape:** Scanning Electron Microscope (SEM) Can observe up to 100,000 times magnification. - **Particle size distribution:** Particle size distribution measurement device Can measure dry powder directly in dry conditions. - **Moisture content:** Infrared moisture meter. - **Bulk density:** Bulk density measurement device. We have about 23 types of analytical equipment. You can view them in the "List of Analytical Equipment" below.

In recent years, the demand for electronic components has increased, and the cosmetics industry, which was affected by the COVID-19 pandemic, is gradually showing signs of recovery. Both electronic components and cosmetics are significantly impacted by contaminants and residues that can arise from raw materials during various manufacturing processes, which can affect the quality of the final product. Our company, specializing in contract manufacturing of chemicals, has installed vacuum shelf dryers in a clean room with a clean class of 100,000, allowing us to dry raw materials for electronic components, cosmetics, and more. To prevent the introduction of foreign substances from outside, we are also equipped with air showers at the entrance. Reducing contamination risks during the drying process leads to improved productivity across the entire manufacturing process. ■ Introduction to Vacuum Shelf Dryers (https://www.nc-ind.com/equipment/000024.php) - Capable of drying up to 720L at once 560L×1, 650L×1, 720L×2, totaling 4 units - Vacuum level: -98kPa, low-temperature drying below 80℃ - Moisture content can be reduced to 0.1% after drying

Among chemical materials, those that are sensitive to heat, such as resins, synthetic rubber, and surfactants, can easily lead to quality defects when exposed to temperatures above 100°C, resulting in: × shape changes × discoloration × decomposition of additives × loss of the material's inherent properties. For such materials, "vacuum drying" under vacuum conditions (-98 kPa) at temperatures below 80°C is optimal. Our company has vacuum dryers capable of accommodating various raw material shapes and quantities, so if you are considering drying, please feel free to consult us. ■ Introduction to Vacuum Drying Equipment Shelf Vacuum Dryer (https://www.nc-ind.com/equipment/000024.php) - Can dry up to 720L (up to 288kg for a bulk density of 0.4) at once - Installed in a clean room Nauta Mixer (https://www.nc-ind.com/equipment/000029.php) - Can dry up to 2,000L at once → High processing capacity, leading to cost reduction! - Simultaneous mixing and drying through rotating and revolving screw arms → Uniform drying in a short time, even for raw materials with different densities.

The filtration equipment known as the "filter press" is commonly used in wastewater treatment and food manufacturing sites, and there are few companies, including ours, that engage in contract manufacturing for chemicals. In addition to solid-liquid separation of slurries, it can also wash the cake within the process, efficiently removing unwanted components. We offer a lab machine that produces palm-sized dewatered cakes and a mass production machine that can adjust production volume by changing the number of filter frames. 【Recommended One-Stop Process】 ■ Slurry adjustment ■ Filter press for filtering, washing, and dewatering the slurry into a cake ⇒ Selection of filter cloths tailored to slurry characteristics is also possible ■ Drying the dewatered cake using a shelf dryer or vacuum agitation dryer ■ Packaging (paper bags, drums, bulk bags, etc.) *For more details, please refer to the PDF materials or feel free to contact us.

Among the more than 30 types of equipment at Nippon Color Industry Co., Ltd., the spray dryer, which can spray-dry slurry (liquid) and turn it into powder in an instant, was among our top-class inquiries in the fiscal year 2021. We offer a lineup ranging from lab-sized machines that can produce from one day, to small machines suitable for production of several dozen to several hundred kilograms, which is not enough to use mass production machines, and mass production machines capable of producing several tens of tons per month. This is recommended for those who want to turn slurry into powder for the first time, or for those who find it difficult to introduce large equipment like a spray dryer due to high hurdles. 【Recommended One-Stop Process】 ■ Slurry adjustment ■ Wet grinding of slurry with a bead mill ⇒ Increases dispersion by reducing and uniformizing particle size in the slurry ■ Powdering slurry with a spray dryer ⇒ Shortens filtration, dehydration, drying, grinding, and classification processes ■ Firing dried powder in a roller hearth kiln ⇒ Increases strength and removes unnecessary components ■ Packaging (paper bags, drums, FIBC, etc.) *For more details, please refer to the PDF materials or feel free to contact us.
