Description

This desiccant refill pack pairs 6 oz of silica gel with 6 oz of activated alumina — the same two-stage desiccant combination used in our Easy Mushroom Drying Kit. Silica gel pulls moisture fast; activated alumina keeps working after the silica gel is full.

Both are reusable. The silica gel has blue indicator beads that turn pink when it's saturated, and you recharge both by baking at 250°F for about 60 minutes. Use it to refill a drying kit or add drying power to any sealed container.

Why growers use two desiccants

  • Fast first stage – Silica gel pulls moisture out quickly at the start of drying.
  • Steady second stage – Activated alumina dries more slowly and keeps removing moisture after the silica gel is full, trapping it in its porous structure.
  • No guesswork – Blue indicator beads in the silica gel turn pink when it needs recharging.
  • Reusable – Bake both at 250°F for about 60 minutes and they're ready again.
  • Easy refill – A larger refill of the two desiccants in our Easy Mushroom Drying Kit.

What's included

  • 6 oz container of silica gel with blue indicator beads
  • 6 oz container of activated alumina

How to use them

  1. Pre-dry. Air-dry fresh mushrooms in front of a fan first so most of the water is already gone.
  2. Load the container. Put both desiccants in the bottom of an airtight container and set the mushrooms on a screen or rack above them.
  3. Seal and wait. Close the container and let the desiccants pull out the remaining moisture until the mushrooms snap cleanly.
  4. Watch the beads. When the indicator beads turn from blue to pink, the silica gel is saturated.
  5. Recharge. Bake both desiccants at 250°F for about 60 minutes, let them cool, and reuse.

Need the whole setup? The Easy Mushroom Drying Kit comes with a 6.5-quart drying chamber, a mesh screen and 4 oz of each desiccant. For larger harvests, a mushroom dehydrator dries more at once.

FAQ

Why use both silica gel and activated alumina?

Silica gel pulls moisture out fast at the start. Activated alumina dries more slowly but keeps removing moisture after the silica gel is full, so together they dry more completely.

How do I know when to recharge them?

The blue indicator beads in the silica gel turn pink when it is saturated.

How do I recharge the desiccants?

Bake them at 250°F for about 60 minutes, let them cool, and they are ready to use again.

Will these fit my Easy Mushroom Drying Kit?

Yes. This is a larger refill of the two desiccants in the Easy Mushroom Drying Kit, and it also works in any airtight container.

Should I pre-dry mushrooms first?

Yes. Air-dry them in front of a fan first so the desiccants only have to remove the last of the moisture.
