This invention relates to a method and a device for thermally treating flour, especially middlings, for hygienic purposes. The device includes modules which are a first, heatable batch mixer () with a pre-mounted depot (). The batch mixer is connected to a drier/cooler () via a look-like flap system (). A second batch mixer () includes a device () for adding additives and a discharge device is mounted behind an additional flap system () that is mounted behind the drier/cooler ().

Method of thermally treating flour for hygienic purposes

This invention relates to a method and a device for thermally treating flour, especially middlings, for hygienic purposes. The device includes modules which are a first, heatable batch mixer () with a pre-mounted depot (). The batch mixer is connected to a drier/cooler () via a lock-like flap system (). A second batch mixer () includes a device () for adding additives and a discharge device is mounted behind an additional flap system () that is mounted behind the drier/cooler ().

Screw extruder and process for controlling the quality of feedstuff

A pellet mill (1) is provided with a control unit with the help of which a desired value of press roll slippage, e.g. zero or a pre-selectable peak value can be maintained. For this purpose, the pellet mill (1) comprises a first measuring unit (27, 28) for measuring the circumferential speed of the perforated die (8) as well as a second measuring unit (23, 24) for measuring the circumferential speed of the press rolls (11, 12). In a comparator (30, 31), the two circumferential speeds are compared and on exceeding a pre-selectable peak value for the difference of the two measured values, a slip signal is created by means of which the mill drive, and/or the supply of basic material to be formed is influenced in such a manner that the slippage will be prevented.

Apparatus for slip regulation of a pellet mill

A pellet mill comprises a perforated annular pellet die having an axis of rotation and first and second ends; and a die carrier rotatable about an axis of rotation and having an annular recess for receiving the first end of the annular pellet die. Fixing devices are secured to the first end of the die and cooperating fixing devices are provided in the annular recess in the die carrier. The fixing devices and the cooperating fixing devices have a first position relative to one another permitting insertion of the first end into the annular recess by relative axial movement of the die and die carrier and a second relative position permitting the transmission of force between the fixing devices and the cooperating fixing devices to draw the die towards the die carrier into a clamped position. Various different devices are provided for generating the force. In addition centering devices are provided which are effective on drawing of the die towards the die carrier to center the die relative to the die carrier. The pellet mill also includes a device for releasing the die from the die carrier.
