Preheat the oven to 250° and line 2 sheet trays with parchment paper.
In a large bowl, combine the pretzels, cheese crackers, rye chips, and sesame sticks. Mix together.
Combine the ranch mix, salt-free ranch seasoning and cayenne together in a small bowl.
Pour the melted butter over the snack mixture and then sprinkle the ranch mixture on top. Mix really well, coating all the pieces with butter and seasoning as best as you can.
Pour half onto each prepared sheet tray and bake for 40 minuets, stirring every 10 minutes.
Let cool fully and then store covered at room temperature for up to 3 weeks.
