日本カラー工業 List of Products and Services

The roller compactor (https://www.nc-ind.com/equipment/000019.php) can compress powder into granules by applying a maximum pressure of 5t/cm. The processes of adding a binder to the powder, dewatering, and drying are combined and shortened into one step. ◎ Advantages of Compacted Granulation ◎ "Easy to handle" → Reduces dust generation and scattering of the powder → Improves weighability, 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, industrial solid catalysts】 　◎ 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. **Examples 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 the dried 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 the list of analytical equipment below.

In the field of chemical research and development, various products are developed towards commercialization by repeatedly going through "raw material development ⇒ process examination ⇒ performance evaluation" on a daily basis. Among these, small-scale prototypes in the early stages of development often come with requests such as: ✓ I want to explore the optimal manufacturing method by repeating the process more times than focusing on quantity. ✓ I am concerned about whether there is equipment available since the raw materials I can prepare are limited... ✓ I want a small sample as soon as possible, ideally in the shortest time frame. We receive many such requests and inquiries. At our company, we use small lab equipment (spray drying, filtration, mixing, grinding) to: ◎ Establish the optimal manufacturing method with any conditions in a single prototype run. ◎ Complete the prototype process in as little as one day. ※ Equipment cleaning and transportation arrangements are separate. This is what we can offer! Furthermore, having actual machines in preparation for future mass production is also one of our strengths. Please take a look at the materials available for download in PDF format to see what equipment is available for small-scale prototypes.

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 occur in the raw materials during various manufacturing processes, affecting the quality of the final products. Our company, specializing in contract manufacturing of chemicals, has installed vacuum shelf dryers in a cleanroom with a clean class of 100,000, allowing us to dry raw materials for electronic components and cosmetics. To prevent foreign substances from being brought in, we also have air showers at the entrances. Reducing contamination risks during the drying process leads to improved productivity across the entire manufacturing process. ■ Introduction to the vacuum shelf dryer (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) - Capable of drying 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) - Capable of drying up to 2,000L at once → High processing capacity, leading to cost reduction! - Simultaneous stirring and drying through rotating and revolving screw arms → Uniform drying in a short time, even for raw materials with different specific gravities.

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 the slurry using the filter press to wash and dewater it into a cake ⇒ Selection of filter cloths tailored to slurry characteristics is also possible ■ Dry 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 one of our top-class inquiries in the fiscal year 2021. We offer a lineup ranging from lab-sized machines that can start production from one day, to small machines suitable for production of several dozen to several hundred kg, which is not enough to require mass production equipment, 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 Bead Mill ⇒ Increases dispersion by reducing and uniformizing particle size within the slurry ■ Powdering Slurry with Spray Dryer ⇒ Shortens filtration, dehydration, drying, grinding, and classification processes ■ Firing Dried Powder in Roller Hearth Kiln ⇒ Increases strength and removes unwanted components ■ Packaging (paper bags, drums, bulk bags, etc.) *For more details, please refer to the PDF materials or feel free to contact us.
