How to increase Torque and reduce speed


i'm building a cat feedar using a rotating hooper..my problem is the rotating speed of the hooper is too fast and don't have enough torque..A few suggestion that i have gather is to buy a new motor with higher ratio.is there any other way to accomplish the same result?

since i have 5 cat.. i'm still looking a way to dispense the food into 5 tray(if possible)..anyone here have any suggestion how to achieve it...Maybe using rotating tray?(but still the same problem with the motor ,not enough power)
