Japan's e-tsutsui (Tsutsui Rika) ultrasonic sieving machine SW-20AT for use in the food and pharmaceutical fields
Japan's e-tsutsui Tsutsui Rika Sonic Sieving Machine SW-20AT for Food and Pharmaceutical Applications

• Working principleUsing the air column vibration method, the sieve frame is not mechanically moved; instead, the air inside the sieve is vibrated to force the sample through the mesh surface, thereby achieving material sieving.

• High-precision screeningIt can achieve high-precision screening operations and is suitable for multi-stage classification with a dry opening of 5μm. It has excellent screening effects for ultrafine powders, effectively separating particles of different sizes to meet various fine screening requirements.

• Efficient and energy-savingThe vibration mode of the air column results in higher screening efficiency, allowing more material to be processed per unit time. Additionally, compared to some traditional screening equipment, it consumes less energy, helping to reduce production costs.

• Long screen lifeSince it does not rely on mechanical vibrations to drive the screen movement, direct friction and collision between the screen and the material are reduced, thereby extending the service life of the screen and lowering the maintenance cost of the equipment.

• Easy to operateThe operation of the equipment is relatively simple and easy to learn, allowing staff to become proficient after minimal training. Additionally, the equipment boasts excellent stability, with a low likelihood of malfunctions during operation, thereby reducing downtime for maintenance.

• Easy to cleanThe structural design is reasonable, with no dead corners, making it easy to clean residual materials inside the sieve. It meets hygiene standards and is suitable for industries with high hygiene requirements, such as food and pharmaceuticals.

Additionally, this equipment can be used in the pharmaceutical industry for sieving drug powders, ensuring uniform particle size and improving drug quality and stability. For example, it can be applied to the classification and sieving of powdered drugs such as antibiotics and vitamins. In the food industry, during the production of food raw materials like flour, starch, powdered sugar, and milk powder, it enables fine sieving of raw materials, removing impurities and substandard particles to ensure the taste and quality of the food.
