After drying, the silica gel that is very hot and should be filled into a suitable container and sealed airtight as possible.
The cooling on the baking sheet under contact with the ambient air will loading the silica gel again and greatly limit the later use in the adsorber.
A prerequisite for the regeneration of a loaded silica gel in a domestic oven is that no oil or other substances are on the surface and the regeneration temperature is observed. 1. Preparations
Set a temperature of 120°C and circulating air to ventilate the silica bulk as well as possible.
The silica gel should be spread as flat as possible in a baking sheet. The flatter the bed, the better the flow through with hot air and the faster the regeneration will take place. 2. Process
Push the baking sheet with as much distance to each other into the oven.
The regeneration time until completely dry depends on the bed height of the bulk and is calculated as follows:
