Multiple Item Dispenser

Allright, as you know nowadays we use a lot of farms and as a consequence we also have a lot of hoppers going on but we also need a way to transport the items from a "slime farm" down in the ground to our item collector/sorter so we use water streams with soulsand and that's all. In order to transport the items from the hoppers down in the ground to the hoppers above we generally use a fast clock that dispenses the items into the water stream an so on. I noticed that this cause a noise that I don't really like and also some lag in my case. My suggestion is to create a block that you'll need to activate using a simple redstone input like a torch that will automatically dispense the items from the hoppers very fast and also without all that noise from the clocks we use an so it will reduce also lag in my opinion. Thank you for your attenention and time!
