RECEIVING OF RAW MATERIALS
|
-
The first operation in the feed processing plant involves the receiving of raw materials into the plant premises.
-
Feed ingredients arrive in gunny bags, or other small containers and in bulk.
-
Ingredients in gunny bags are checked physically for moisture, contamination, smell and for soundness of the material.
-
Ingredients must then be stored in a dry location with proper protection from rodent and insect infestation.
-
Sacked stocks are then rotated regularly to minimize moldiness, product degradation, and insect infestation.
-
Bulk ingredients are handled according to their physical form. Liquid ingredients, such as oils and molasses, are generally stored in bulk tanks.
-
Proper storage temperature is maintained and the filter screens are checked periodically.
-
Solid bulk ingredients such as grains, oil meals, etc., are cleaned with a scalper to remove foreign material prior to storage in bins.
-
Bin temperatures are monitored to prevent heating due to grain respiration.
-
In the feed manufacturing process, evaluation of the feed ingredients is important for achieving consistent quality.
-
If the quality of the ingredient can be assessed before it is unloaded from the truck, it would save both trouble and money. There are different types of evaluations.
