Abstract: A device for filling containers has a top tray that engages with a bottom tray to fill containers. The bottom tray has a plurality of receiving slots to hold the containers and the top tray has a series of sleeves to insert into the containers for filling. An optional side tray collects excess food for later use or disposal. A method of using the device has the containers being secured by a plurality of receiving slots on the bottom tray, the plurality of sleeves on the top tray inserting into the plurality of containers, and food transferred or poured onto the top surface of the top tray, travelling through top openings on each of the plurality of sleeves to the containers.

Abstract: A method for treating a contaminated metal powder obtained as a residue of a metal deposition process is provided. The method includes receiving, by a vibratory filtering apparatus, the contaminated metal powder generated during the metal deposition process. The contaminated metal powder is received from a top end of the vibratory filtering apparatus. The method further includes filtering the contaminated metal powder by passing the contaminated metal powder through a plurality of filter plates. The plurality of filter plates are so positioned sequentially along a height of the vibratory filtering apparatus that dimensions of a first plurality of holes of a filter plate are larger than dimensions of a second plurality of holes of a subsequent filter plate placed below. The vibratory filtering apparatus is vibrating during the filtering of the contaminated metal powder. The method further includes obtaining, by a receptacle, a filtered metal powder that is reusable.
