Dry feeding
While for liquid feeding the various components (flour, CCM, whey, silage corn, potato pulp, etc.) get mixed together and can be fed homogeneously, this applies for dry feeding only a very limited way.
From our point of view there are three variations:
1.) The simple variant:
A flour silo close to the pigsty, from where a short auger feeds the flour into the feedstuff pipeline. In the pipeline a chain with cams pulls the flour into the pigsty, where it turns out of taps into the automatic feeder. The amount of feed can be adjusted through telescopic tubes in the feeder. This variant is often extended to a second flour silo in order to completely empty the flour silo prior to a new flour delivery. For this purpose there is a toggle switch which releases the flour screw alternately.
2.) Semiautomatic dry feeding:
From up to four different flour silos the respective type of feedstuff gets transported into the feedstuff pipeline, in a user predetermined order. Each tap of the automatic feeders is operated by compressed air and can be assigned (open/close) to the matching feedstuff type through ball valves. When the first automatic feeders are stuffed with the matching type of feedstuff, the residual stuff in the pipeline is emptied into the origin silo. Subsequently, the other predefined varieties are fed into the tube system, with the appropriate emptying process in between. The quantity control is performed as in the simple variant on telescopic tubes in the automatic feeders.
