Thoughts on the batching sequence of premix

This topic is a little big. We are a feed manufacturer, and the production of premix (so-called small material) has always been a hidden trouble in quality. We now weigh choline, salt and acidifiers separately without premixing. Residual amino acid enzyme preparation multi-dimensional ore to add medicine feed additive carrier, how to determine this order? Our mixer is a 250 kg mixer. PS would like to know what your output is? -- monthly sales are about 12000-15000-- well, that's great. -looking forward to the expert's advice! Light first, then heavy, first more and then less, but calcium hydrogen and stone powder should be added separately from others as far as possible-- no matter how much you match. All carrier 50% murine-drug additive-carrier 50% murine-directly added to the mixer First more and then less.-- my current mode of operation: the formula is ordered to use a fixed mode (one to four sequential weighing): one: salt, baking soda and other two: amino acids and premixtures three: mineral addition and multi-dimensional four: additives (mainly refers to: pharmaceutical feed additives, enzyme preparations, Improver, etc.) batching order: weigh 30% carrier first-1, 2, 3, 4-70% carrier to ensure the mixer filling coefficient 0.7 That is, 230-240 kg per plate. Is the main thing all right? Also ask the master to correct! Vitamins were added last and antioxidants were added earlier.
