Floating Feed Oil coating Machine
Please describe the working principle of a floating feed oil coating machine used in floating fish feed production. How does it ensure proper oil penetration and coating of the extruded pellets without compromising buoyancy and pellet integrity? Discuss the importance of oil viscosity, feed temperature, and coating time in the efficiency of the process. What challenges may arise if these parameters are not properly controlled?

Well compiled

if the parameter are not well control,too much oil reduce Oxygen available in ponds/tanks/,pollute water.reduces shelf life.

the oil doesnt have negative effect on the boyancy and integrity of the pellets but add the quantity of oil in the recipe to it.the oil also enhance floatability.

What is the optimal temperature to maintain in the reserve oil tank to ensure smooth and consistent flow into the horizontal oil coater drum?

This is rather complicated question. If your extruded pellets meet your specifications for density and by inference buoyancy and moisture content the method of fat coating can be a measured amount of fat per unit of pellets in a tumble-drum with timed residence before exiting; can be a cascade of pellets over a spinning disc with a measured amount of fat sprayed on the pellets.
This is not a “hit-or-miss” operation – if your pellets are not sufficiently dry before fat coating the fat will seal the moisture in perhaps causing molding issues; if the pellets are too cool when fat coated the fat will not penetrate the pellet and perhaps “wash” off when introduced to the water causing water quality problems. If the ratio of fat to pellet is too great the density of the pellet will be altered perhaps causing the pellet to sink – so application of the fat must be accurate – too much not, too little not good.

Thanks sir for your insights. I appreciate your tips.

Dear Sir
What is the optimal temperature to maintain in the reserve oil tank to ensure smooth and consistent flow into the horizontal oil coater drum?

the fat coater can using example of drum coater.as a wheel which the drum continously run on it.
Inside the fat coater a noozles on a horizontal line,behind the coater,there is a pipe that enters it ,there is a process bin connected to the coater with a scale to measure the rate of flow of dried pellets that enter it,
has a materials which flow through the scale that has a been caliberated on the PLC ,the refined or crude oil doses according to the kilogram of feed dropping.
