What Is a Foreign Material Separator?
A foreign material separator is a device that removes foreign materials during powder processing to maintain high quality.
It is intended to improve work accuracy and reduce labor costs by reducing the number of personnel performing sorting, and covering oversights caused by human error.
Foreign matter removal methods include image-based identification, powder particle characteristics, and methods using magnetic force. Selecting the most effective method according to the production process and characteristics of the foreign matter ensures reliable removal.
Uses of Foreign Material Separators
Foreign material separators are used in powder processing to remove foreign matter that has been introduced during the process.
They are used in a wide range of fields, including food manufacturing, pharmaceutical manufacturing, and the chemical industry. For example, in the food field, where hygiene is important, foreign matter such as stones, sand, metals, and hair mixed in with dried food such as grains and spices are identified and removed.
Principle of Foreign Material Separators
In image-based removal, the powder on the conveyor is photographed, and a sensor is used to recognize the color and shape of the powder to remove foreign matter.
In methods that use particle characteristics, the powder is vibrated and sieved according to differences in particle size, and differences in specific gravity are analyzed to distinguish between foreign matter and powder for removal.
Magnetic removal methods use magnetic force to remove foreign matter such as metals.
