Fine mesh strainer for sifting PDZ off my trays

[Colorful egg carton]

Tried a kitty litter scoop too much poop fell thru it.

So I bought one off Amazon it’s a reptile sand mesh shovel, but it’s the size of a sandwich and I need this large scale. Seems dumb to stand there and sift in little batches like I’m making Jiffy Pop and adds dust to the air when I’m doing it. I have 20 ft of tray to scoop and sift.

Using a long drywall scraper to scrape that’s a gem.
Pasta mesh strainers and flour sifters look too tight the pdz won’t fall thru that.

Can I make one or something??
What would you do?

Amazon has full size shovels with mesh insert in the scoop. Used by treasure hunters to filter sand/loose dirt.
