Abstract
The present invention relates to a method of mixing inhomogeneous flowable food material, fodder material, or pharmaceutical material in a tank provided with mixing devices. The method comprises measuring and registering the content of one or a number of components in samples taken from the material in the tank.
Claims23
A method of mixing a flowable material, which comprises:
- a) placing at least one unhomogeneous food, fodder or pharmaceutical material having a form or size that can lead to uneven component measurement into a tank provided with mixing devices;
- b) measuring and registering the content of at least one component from samples taken from the material in the tank by removing material from the tank through a tube which is situated adjacent the tank and which communicates with the internal space of the tank;
- c) moving the removed material to a segment of the tube adapted for making measurements;
- d) measuring the effect caused by the material placed in said tube segment on electromagnetic energy made to enter the tube while the material is retained therein;
- e) repeating steps c-d, optionally while introducing completely or partly new material in the tube segment;
- and
- f) registering at least one measurement value from the individual measuring procedure to determine the content of the components to be mixed.
4 more elements
A plant for mixing an inhomogeneous flowable food, fodder or pharmaceutical material, comprising:
- a tank (2) for combining the material, a plurality of mixing devices (4), an examining unit adjacent the tank and comprising a tube (10) having an opening communicating with the internal space of the tank (2) for removing material from the latter, in said tube (10), a movable closure member (17) situated in said tube adjacent the opening for receiving material, a conveying member (18) for conveying material having been removed through said opening into a segment (10b) of said tube (10) adapted for carrying out measurements, a measuring device (32-37;
- 40, 41;
- 50-56;
- 60-64) situated adjacent said segment (10b) of said tube (10) and adapted to transmit electromagnetic energy into said segment and to measure the influence on this energy exerted by the material being present in said segment, a control unit (6a) to cause the measuring procedure comprising the introduction of completely or partly new material in said segment (10b) and measuring of its influence on electromagnetic energy, to be repeated, and a recording unit connected to said measuring device and adapted to record individual measurement values or sets of same for material having been measured in the respective measuring procedures.
