Pour your solution in a pyrex dish, place it near a window and aim a fan directly on it. In SWIM's experience this will fully evaporate in about 10-12 hours, depending on how much fluid you have. If you've got a lot, spread it out in a couple of dishes to increase surface area.
If you're referring to slices of cacti, SWIM had the best luck dicing the cacti up and letting it air dry for a few days, in the sun if possible. Then, shred up the semi-dry chunks using a food processor/blender, spread them out in a pan and aim a fan at them. This should dry it out completely overnight, depending on how humid your area is.
