• Prototype Services

Here is a brief introduction to the "spray dryer" used in SD science. We adopt the "rotary atomizer method" as the spraying method. Compared to other spraying methods, it is easier to control the particle size, allowing us to obtain products with uniform particle sizes. Additionally, we use a "two-point collection method" for product collection, recovering from both below the drying chamber and below the cyclone. This results in a good overall product recovery rate and eliminates the need for mixing in subsequent processes, thereby increasing production efficiency. We also welcome factory tours, so please feel free to reach out to us. 【Adopted Methods】 ■ Rotary Atomizer Method ■ Two-Point Collection Method *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the process from when you start considering our services to the delivery of the powdered product. First, please contact us via our website or by phone. After a meeting and proposal, we will conduct test processing using a testing machine (prototype production). (The initial test with the testing machine is free!) After that, if you evaluate the prototype and are satisfied, we will proceed to test processing with the actual production machine. If you are satisfied with the prototype from the actual production machine, we will provide you with a quotation based on the test results. After confirming the order and processing details, we will carry out the actual production. We will ensure timely delivery to the specified location. For any other detailed conditions, please feel free to contact us. 【Flow of Contracted Processing】 ■ Inquiry for contracted processing → Meeting / Proposal → Test processing with testing machine → Meeting / Proposal → Test processing with actual production machine → Submission of quotation → Order / Processing details meeting → Contracted processing → Delivery *For more details, please refer to the PDF document or feel free to contact us.

In production using a spray dryer, contamination (hereinafter referred to as "contamination") is a serious issue that is always present. Neglecting contamination measures can lead not only to problems in the subsequent processes of our clients but, in the worst case, can damage our clients' trust. Our company has introduced a CIP (Cleaning in Place) automatic cleaning system for the cleaning of drying equipment, and we have installed numerous inspection ports along the line to conduct visual checks during all cleaning processes. Additionally, since we are a specialized factory for contract processing that dries a large number of raw liquids, we use flexible piping between the raw liquid tanks and the liquid transfer pumps, disassembling and cleaning them for each product changeover. We have been and will continue to work on contamination measures. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the production equipment we have. We possess a "spray dryer" that can continuously dry, as well as "testing equipment" for conducting various tests, and "purification equipment" that filters wastewater generated during equipment cleaning over time before discharging it. Please feel free to contact us when needed. 【Equipment Owned】 ■ Spray Dryer (for production) - Sprays the raw liquid into a hot air stream using a micronization device for continuous drying. ■ Testing Equipment - Conducts various tests. ■ Purification Equipment - Filters wastewater generated during equipment cleaning over time before discharging. *For more details, please refer to the PDF document or feel free to contact us.

The "Spray Dryer" is a spray drying device that continuously dries liquid materials such as emulsions and slurries by atomizing them into a hot air stream using a micronization device. The sprayed droplets become spherical due to surface tension, resulting in dried particles that are also close to spherical, allowing for the production of highly flowable dried powders. Additionally, it dries materials in a shorter time compared to other drying equipment (with a small thermal history), making it suitable for drying products that are sensitive to heat. 【Features】 ■ Dried particles are close to spherical, allowing for the production of highly flowable dried powders. ■ Dries materials in a shorter time compared to other drying equipment (with a small thermal history). ■ Suitable for drying products that are sensitive to heat. ■ Rotary atomizer method (disk type). ■ Particle size can be adjusted by changing spraying conditions such as rotation speed. *For more details, please refer to the PDF document or feel free to contact us.
