PNEUMATIC FEED INGREDIENT DELIVERY SYSTEM AND METHOD

摘要

A system and method provides for delivering dry feed ingredients through delivery lines using vacuum propelling techniques, and to mix the dry feed ingredients, without use of liquids such as water. By avoiding use of a liquid during dispensing and transporting to a mixing vessel, lower infrastructure costs can be achieved while also avoiding problems such as freezing related to systems that carry liquids. A method is also provided for delivering feed ingredients to achieve optimal mixing between ingredients to prevent ingredient damage by over-mixing, and undesirable separation of ingredients. Another method is provided for delivering feed ingredients to prevent cross contamination between ingredients in a batch or between ingredients in separate batches. A cleaning ingredient is used to clean selected lines to prevent the contamination, such as corn or grain, therefore also avoiding use of a liquid.
