Handover: Upstream
Collect recipe ranges, finished form, pellet die diameter in millimetres if pelleting is in scope, and whether cooling and bagging must match the same t/h as the mill. If floating or sinking aquafeed is actually required, the brief asks livestock-line bidders to stop mixing pellet-mill ratings with extrusion, drying and coating. Bühler’s aquafeed pages distinguish floating and sinking applications; that split is a question to copy, not a certificate from this desk.
Control boundary
Ask every bidder to list: receiving and dosing; grinding; mixing; conditioner and pellet mill or extruder; cooler or dryer; coating if used; bagging; dies and spare rolls; installation; training; spare parts; shipping terms. Items left blank are treated as excluded. Connected load, three-phase supply and steam demand belong in the same table so plant contractors are not guessing. Water-stability or pellet-durability claims must name the test duration and sample method—see the aquafeed note.
