Yes all of our dehydrators, excluding our 116 hook rotisserie unit, come with 304 food-grade stainless steel mesh trays as well as a stainless steel drip tray at the bottom of each zone. Additional mesh trays or pan trays may be purchased on top of this. The mesh trays that come with the unit cannot be substituted for pan trays. You may also purchase non-stick mats from our accessories section if desired.
