When attaching heat shrink film to containers such as glass bottles, there is a process that uses live steam. After attachment, products often have water droplets on them, and compressed air is frequently used to remove these droplets. We can remove water droplets using an energy-saving method that employs a blower (turbo blower) instead of compressed air. For example, compared to methods using compressed air, we can achieve this at less than one-tenth to one-fifteenth of the electricity cost. As a blower manufacturer, we will select and propose products that match your equipment. 【Features of this device】 ■ Energy-saving ■ All-in-one solution for removing paper dust to dust collection ■ High-performance filter installed to ensure clean blowing air *Please feel free to contact us.

The manufacturer of the blower used by the customer is no longer in business, so we would like to introduce a case where we manufactured a replacement machine. The customer had no drawings, only a photo of the machine's nameplate. After taking a photo of the actual machine and sending it to us, we confirmed the details and determined that a new replacement was necessary. We also received feedback from the customer, and as a result, the project included the manufacturing of the machine and the replacement work on-site. As a result, the customer's production equipment was successfully operational, and the following year, we received an order that included an update project for the same existing product. [Case Study] ■ Issue: There is no company to ask questions, so on-site investigation is necessary for machine information. ■ Response: - First, we requested any available materials from the customer (drawings, performance curves, product photos, etc.) *For more details, please refer to the PDF document or feel free to contact us.

The dust hopper at the bottom of the dust collector was experiencing issues with uneven dust distribution. To address this problem, we conducted airflow analysis using CFD (Computational Fluid Dynamics) and carried out modification work. The results after the modifications were as expected, and the problem-solving method using CFD analysis was recognized, ultimately leading to the acquisition of new orders for expansion work. Given our track record, the customer was pleased. [Case Study] ■ Problem: Uneven dust distribution in the dust hopper at the bottom of the dust collector ■ Response: - Conducted airflow analysis using CFD as an approach to problem-solving - Visualized airflow and pressure fluctuations inside the dust collector to confirm the details - Ensured stable effects could be achieved *For more details, please refer to the PDF document or feel free to contact us.

To sort raw materials and foreign substances using wind power, it was necessary to change the amount of air blown based on the weight of the raw materials. Therefore, to create a difference in the internal airflow of a single wind sorting machine, we implemented a double fan instead of a single fan, which allowed us to generate airflow with different characteristics within one machine. Previously, foreign substance removal was done manually, but with this method, only the final confirmation sorting requires manual labor, resulting in a foreign substance removal rate of over 98%. [Issues] - Removal of foreign substances from tsukudani raw materials (shredded kelp) - The need to control the structure of the wind sorting machine and two different airflows in an all-in-one manner *For more details, please refer to the PDF document or feel free to contact us.

There were issues with the disposal of exhaust gas after cleaning, which contained film gloss wax components. Therefore, various spray nozzles were used in the exhaust gas inflow section of the wet dust collector to increase the particle size of the target substances through forced humidification of the entire gas, thereby improving the dust collection capability of the wet dust collector. After the installation of the equipment, the exhaust gas became cleaner, and there were no complaints from nearby residents, along with a significant reduction in odor. [Problems] - The vaporized oil had a very small particle size, making it a very difficult substance to process unless it mixed efficiently with water. - When washing gas containing oil with water, there were issues with wastewater, and depending on the situation, there was a risk of exceeding environmental regulatory limits. *For more details, please refer to the PDF document or feel free to contact us.*

We confirmed on-site how the dust generated during the operation of the dust collector behaves in relation to the plastic bag inside the drum and what factors cause problems. It was found that there was a significant amount of residual air between the inside of the drum and the plastic bag covering it, and we observed the phenomenon of air and the plastic bag being drawn toward the hopper side. To reduce the air in the gap between the drum and the plastic bag to below the internal pressure of the dust collector, we installed a vacuum piping and an adjustment valve to the drum to adjust the atmospheric pressure difference. As a result, the inner plastic gradually became closely adhered to the inside of the drum, effectively achieving dust collection capacity. [Problems] - It is unavoidable to separately install a metal cage to prevent the dust collection plastic bag from floating inside the dust collection drum. - The removal and installation of this is cumbersome. - Additionally, the workers were covered in dust. *For more details, please refer to the PDF document or feel free to contact us.*

The separator had a predetermined airflow capacity based on its size, but adjustments were needed at the limit of the acceptable airflow, leading to the issue of "bookbinding cut paper pieces not falling smoothly from the lower hopper." Therefore, we conducted a site inspection to confirm the type and quantity of collected materials and the falling condition of the bookbinding cut paper pieces. By changing the routing of the air intake duct piping, we altered the direction of the airflow entering the separator. As a result, stable air transport and recovery of the bookbinding cut paper pieces were achieved, allowing for stable 24-hour operations at the factory. [Case Study] ■ Problem: Bookbinding cut paper pieces do not fall smoothly from the lower hopper. ■ Results - Achieved stable bookbinding transport and recovery. - Enabled stable 24-hour operations at the factory. *For more details, please refer to the PDF document or feel free to contact us.

At a certain food factory, they faced the challenge of wanting to significantly speed up the time for soaking in water or seasoning liquid compared to traditional manual methods, while also improving production efficiency and reducing labor through the use of a blanching device. To address this, they adopted a motor with a brake for the basket inversion. The stopping position of the basket was made easy to adjust in increments, with a kick plate for the limit switch welded to a slit collar. As a result, work could be performed at a stopping position of the basket that matched the height of the workers, reducing the manufacturing process by one step compared to usual, thereby increasing production efficiency. [Case Study] ■ Problem - Want to significantly speed up the soaking time in water or seasoning liquid compared to traditional manual methods. - Absolutely want to minimize manual labor (aiming for automation). ■ Effect - The time saved per operation reduced from the traditional time of approximately 45 minutes to 30 minutes, achieving labor savings over four operations per day. *For more details, please refer to the PDF document or feel free to contact us.

The tack labels for the collected items have adhesive on one side, making air transport difficult, and there was a problem with the adhesive strength of the tack labels varying by product. Therefore, by applying a non-adhesive treatment to various suction components, we prevented adhesion inside the piping. As a result, the workload for operators on-site was reduced, and the number of machines each operator could handle increased, significantly contributing to improved production efficiency. [Results] - No adhesion occurred inside the piping, achieving 24-hour unmanned operation as planned. - The workload for operators on-site was reduced, allowing them to handle more machines. - This significantly contributed to production improvements. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce examples of solutions to problems with dust collectors (wet and dry types). When the internal filter of the electric dust collector for oil vapor recovery became clogged, the collection efficiency drastically decreased, leading to complaints from nearby residents due to the leaked exhaust gas. To address this, we made improvements to the exhaust gas inflow section of the wet dust collector, increased the particle size of the material being processed, and enhanced the collection capacity of the wet dust collector. After the installation of the equipment, the exhaust gas became clean, and complaints from nearby residents ceased. Additionally, we have resolved issues with dry dust collectors, such as early filter wear due to abrasive dust inflow, leading to dust leakage. [Case Studies] < Dust Collector (Wet) > ■ Exhaust after washing exhaust gas containing film gloss wax components < Dust Collector (Dry) > ■ Effective use of plastic bags installed inside the dust collection drum after dust collection ■ Improvement of dust leakage due to early filter wear ■ Issue of uneven dust accumulation in the dust hopper at the bottom of the dust collector *For more details, please feel free to contact us.
