Dust collector with a filter that can be washed completely - "Dust collector with internal cleaning function"
A dust collector that can automatically clean and dry without removing the filter! Adopted in the granulation process of a major pharmaceutical manufacturer!
This dust collector allows for the avoidance of contamination inside the container and the risk of environmental pollution through manual filter replacement and internal cleaning operations. 【Features】 - Bug-in-bag-out system, passes ISPE particle containment performance tests, compatible with clean rooms - The interior of the container, including the filter element, can be completely cleaned and sterilized (HACCP management compliant) - No need to open maintenance doors or remove filter elements due to sealed processing - No risk of contamination or bacteria entering the dust collection container - Extremely safe, with no risk of worker exposure during filter replacement - Capable of automatic cleaning and sterilization, reducing the time required for switching between different powders 【Case Study】 Location: Granulation and coating process line of a pharmaceutical manufacturer Purpose: To collect fine powders generated and ensure cleanliness in the area ● Concern.. There was a need to reduce the hassle of cleaning or replacing filters when they became clogged or when switching the manufacturing line to collect different powders, while ensuring the safety of workers. ○ Solution! Cleaning operations are performed within the dust collector itself (shower cleaning) and drying is also achieved. Additionally, there is no risk of worker exposure to powders.

basic information
Until now, maintenance doors and other features have been installed on dust collection containers, allowing for the removal of filter elements to manually clean the inner walls of the dust collection container and the filter elements. However, this cleaning method poses a risk of contamination by bacteria and other contaminants entering the dust collection container due to the need to open the maintenance door during the process. Additionally, if the powder being collected contains environmental hormones or hazardous substances, there is a risk of environmental pollution and danger to the cleaning personnel. Ryuki Engineering has developed a method that divides the dust collection container, which houses the filter elements, into an upstream dust collection chamber and a downstream filtration chamber, each equipped with supply and discharge paths for cleaning liquid and opening and closing valves. This allows for the safe cleaning of not only the filter elements but also the dust collection container. The filter elements utilize surface filtration with a permeable Teflon membrane, enabling complete cleaning by applying pulse shock waves during immersion after dust removal. Furthermore, using high-temperature water for flushing can eliminate general bacteria. This method has already been adopted by major pharmaceutical manufacturers.
