Bring a large pot of lightly salted water to a boil. Add pasta, cook for 8 to 10 minutes, until al dente. Drain, and cool.
In a large bowl, mix the cooled pasta, creamy salad dressing, ranch dressing mix, tuna, Cheddar cheese, apple, carrot, and raisins. Chill 1 hour in the refrigerator before serving.
