Abstract

An apparatus for the continuous manufacture of a mixed fodder comprises a stationary drum having an infeed opening for straw bales at one end of the peripheral drum wall and an outlet for finished fodder mix at the opposite end. Centrally of the drum there rotates a shaft which carries chopping means in the region of the infeed opening and mixing means in a subsequent longitudinal section. For introducing solid additives there are provided one or more openigns at the first mentioned end of the drum. A liquid binding agent can be supplied through the hollow shaft and be sprayed through nozzles secured in the section of the shaft which carries the mixing means. Further liquid constituents may, if desired, be supplied from the opposite shaft end and be sprayed through other nozzles in the shaft. The apparatus is very compact because all constituents are introduced into the drum and processed and mixed therein. It has a low power consumption and it delivers a very homogeneous mixture. The chopping means and/or the mixing means may be shaped so as to create an air stream through the drum from the infeed end towards the outlet in order to support the travel of material towards the outlet.

Dependent claims

Apparatus for the continuous manufacture of a mixed fodder, the constituents of which comprise chopped straw, at least one solid additive and at least one liquid additive, said apparatus comprising

a stationary drum comprising a pheripheral wall and two end walls and having at one end thereof a straw bale infeed opening in its peripheral wall and at least one further infeed opening for said solid additive, and at its opposite end an outlet for the finished fodder mix,
means for feeding straw bales into said drum through said straw bale infeed opening,
a rotary shaft extending centrally through the interior of said drum and means for rotating said shaft at a relatively high rate of revolution,
a plurality of axially staggered chopping means secured to said shaft within a first longitudinal section thereof aligned with said straw bale infeed opening,
means for mixing said fodder constituents secured to said shaft within a second longitudinal section thereof intermediate said chopping means and said drum outlet,
the chopping means and mixing means being configured for conveying the chopped and mixed fodder constituents towards the outlet of the drum,
and nozzles extending into the interior of said drum for injecting said liquid additive towards the mixture of fodder constituents traveling along the peripheral drum wall towards the drum outlet.
