"Isn't it possible to create a more efficient vacuum dryer...?" The answer lies in "high radiation"! Compared to our conventional products, we have achieved a drying rate that is more than double under the same temperature conditions, and reduced the drying time to less than half. In a vacuum environment, heating through convection is not possible, so the heating methods are conduction or radiation. Achieving high radiation under vacuum means that heating can be done quickly, leading to significant cost reductions. By applying our unique groundbreaking special processing (patent pending) to the heat source section of the vacuum dryer, we have successfully increased the radiation heat in a vacuum, and it has been confirmed that the heat absorption of the workpiece has significantly improved. Our technology can be applied to any model of our vacuum dryers, and comparative testing with test machines is also possible.

We have prepared a demonstration test machine to verify the deodorization effect. There are many types of odor components that can be oxidatively purified, such as organic solvent gases (VOCs) and biochemical odors. The temperature at which oxidation purification can occur varies depending on the component, so it is necessary to confirm the purification temperature with a catalyst when multiple components are mixed. Additionally, even if 99% purification is achieved, some odor may remain. - Can it be purified using a catalytic combustion method? - Will any odor remain? - What are the running costs (electricity)? By addressing these concerns through a demonstration test, you can confidently introduce a catalytic combustion deodorization system. We will listen to the situation regarding the exhaust gas and odors that you are facing, and after prior discussions, we will determine the method and schedule for the demonstration test. (Note: We may decline based on the judgment of the odor components and their occurrence.)

In the manufacturing of raw materials that require high quality, such as battery materials, ceramic materials, carbon, and resin materials, high precision and uniformity are necessary for heating temperature history, atmospheric conditions, and holding time. For drying and heat treating large quantities of powdery substances, a rotary kiln that allows for continuous supply and discharge is optimal compared to static heat treatment methods or batch methods. The rotary kiln (SGV series) has achieved continuous and high-precision uniform heating treatment of temperature history through our unique method of moving raw materials along a spiral groove (formed by guide blades fixed to the inner wall of the retort). We provide a compact device that meets requests for optimal heat treatment considering raw material characteristics, selection of retort material, temperature/time/atmosphere control, and automation of supply/discharge.

We are considering drying and heat treatment using a rotary kiln method, and we are preparing a demonstration test machine for customers who are troubled by the following questions: - Is it possible to dry and heat treat using the rotary kiln method? - What time and temperature can be used for heat treatment? - We want to determine the size and specifications of the production machine. Based on the results of the demonstration test, we will design and propose the optimal rotary kiln. Please let us know the material specifications, drying and heat treatment conditions, and target specifications you are considering. After a preliminary meeting, we will decide on the method, schedule, and costs for the demonstration test. (Please note that we may decline based on factors such as material flowability and generated gases.)
