Patent ID: 7717353

Claim:
An apparatus for mixing and dispensing flowable materials, comprising: a mixing chamber; a first hopper that retains a first flowable material, connected to said mixing chamber; a first valve associated with said first hopper, wherein said first valve regulates the flow of the first flowable material from said first hopper to said mixing chamber; a water pump unit; a control that selectively controls said first valve and selectively controls said water pump unit; a second hopper that retains a second flowable material, connected to said mixing chamber, wherein said first valve is associated with said second hopper and regulates the flow of the second flowable material from said second hopper to said mixing chamber, and wherein said control selectively controls said second valve; a third hopper that retains a third flowable material, connected to said mixing chamber; a fourth hopper that retains a fourth flowable material, connected to said mixing chamber; a second valve associate with said third hopper and fourth hopper, wherein said second valve regulates the flow of the third flowable material from said third hopper to said mixing chamber and the flow of said fourth flowable material from said fourth hopper to said mixing chamber; wherein said control selectively controls said second valve; a fifth hopper that retains a fifth flowable material connected to said mixing chamber; a sixth hopper that retains a sixth flowable material connected to said mixing chamber; a third valve associated with said fifth hopper and sixth hopper, wherein said third valve regulates the flow of said fifth flowable material from said fifth hopper to said mixing chamber and the flow of said sixth flowable material from said sixth hopper to said mixing chamber; wherein said control selectively controls said third valve; a seventh hopper that retains a seventh flowable material connected to said mixing chamber; a fourth valve connected to said seventh hopper, wherein said fourth valve regulates the flow of said seventh flowable material from said seventh hopper to said mixing chamber, wherein said control selectively controls said fourth valve; a hydraulic manifold; a hydraulic input; and a reservoir return, wherein said hydraulic manifold is connected to a hydraulic input and a reservoir return and to said mixing chamber.
