Process and system for coating a feed composition with a feed additive

A system for applying at least one liquid feed additive to a feed composition comprising:

• a liquid additive line;
• a dilution agent line;
• a connecting device connecting said liquid additive line with said dilution agent line for combining a dilution agent with a liquid feed additive in order to form a feed solution;
• a pump located along said liquid additive line, said pump for pumping said liquid feed additive to said connecting device for combining said liquid feed additive with said dilution agent;
• a flow meter located along said liquid additive line for monitoring the flow rate of said liquid additive;
• a spray chamber for applying said feed solution onto a feed composition, said spray chamber including at least one spray device in fluid communication with said connecting device, said spray device for spraying said feed solution onto said solid feed composition;
• a solid feed stream in communication with a solid feed measuring device for measuring the flow rate of a solid feed composition contained in said solid feed stream;
• and
• a controller in communication with said pump, said flow meter, and said solid feed measuring device, said controller being configured to receive information from said flow meter regarding the flow rate of said liquid feed additive and from said solid feed measuring device regarding the flow rate of a feed composition and wherein said controller, based on said information received from said flow meter and from said solid feed measuring device, is further configured to control said pump for applying predetermined amounts of said liquid feed additive onto said feed composition.

A system for applying a liquid feed additive to a feed composition comprising:

• a mixing tank;
• a liquid additive line for supplying a liquid feed additive to said mixing tank;
• a dilution agent line for supplying a dilution agent to said mixing tank;
• at least one measuring device configured to measure the amount of a liquid additive and a dilution agent being fed to said mixing tank in forming a feed solution;
• a dispensing tank in fluid communication with said mixing tank for receiving said feed solution therefrom, said dispensing tank also being in fluid communication with a recirculation conduit and an effluent;
• a flow control device for selectively dispensing said feed solution from said dispensing tank into said recirculation conduit or said effluent;
• and
• a spray device in fluid communication with said effluent for applying said feed solution onto a feed composition.

A system for applying at least one liquid feed additive to a feed composition comprising:

• a liquid additive line;
• a dilution agent line;
• a first pressure control device located along said dilution agent line for maintaining a dilution agent at a substantially constant pressure within said dilution agent line;
• a connecting device connecting said liquid additive line with said dilution agent line for combining said dilution agent with said liquid feed additive in order to form a feed solution;
• a pump located along said liquid additive line, said pump for pumping said liquid feed additive to said connecting device for combining said liquid feed additive with said dilution agent;
• a spray device in fluid communication with said connecting device, said spray device for spraying said feed solution onto a solid feed composition;
• a controller in communication with said pump, wherein said controller is configured to control said pump so as to combine selected amounts of said liquid additive with said dilution agent;
• and
• a solid feed stream in communication with a solid feed measuring device for measuring the flow rate of a solid feed composition contained in said solid feed stream, said solid feed measuring device being in communication with said controller, said controller being configured to receive information from said solid feed measuring device and, based on said information, to control said pump for controlling the amount of said liquid feed additive that is combined with said dilution agent in response to flow rate fluctuations of said feed composition.

A system for applying at least one liquid feed additive to a feed composition comprising:

• a liquid additive line;
• a dilution agent line;
• a first pressure control device located along said dilution agent line for maintaining a dilution agent at a substantially constant pressure within said dilution agent line;
• a connecting device connecting said liquid additive line with said dilution agent line for combining said dilution agent with said liquid feed additive in order to form a feed solution, said connecting device being configured such that said liquid feed additive is only combined with said dilution agent when the pressure of said liquid feed additive within said liquid additive line is greater than the pressure of said dilution agent within said dilution agent line;
• a pump located along said liquid additive line, said pump for pumping said liquid feed additive to said connecting device for combining said liquid feed additive with said dilution agent;
• a spray device in fluid communication with said connecting device, said spray device for spraying said feed solution onto a solid feed composition;
• and
