7. The coater of claim 1 , wherein the coupling is removably attached to the motor.
8. The coater of claim 1 , wherein a position of the spray bar is adjustable from an outside of the housing.
9. The coater of claim 8 , wherein the location of the spray bar with respect to the material being coated is adjustable from the outside of the housing.
10. The coater of claim 9 further including:
a gun to bed distance monitoring system.
11. A coater for coating a material with a solution or a suspension, the coater comprising:
a housing;
a removable cradle including a support and a slot positioned within the housing;
a dolly slideably engagable with the cradle for removal and support of the cradle from the housing, the dolly including a plurality of wheels to permit the dolly to slide in and out of the housing;
a first drum including an annular flange at an access end, the first drum positioned on the cradle and supported at the access end with the support and supported at a drive end by the slot, wherein the cradle facilitates removal of and replacement of the first drum with a second drum having a different size than the first drum;
an access door positioned at the access end of the first drum and permitting removal of the cradle and replacement of the first drum with the second drum; and
a spray bar extending into a mixing chamber of the drum to coat the material with the solution or the suspension.
12. The coater of claim 11 further comprising:
a process port connected within the access door, the process port permitting access to a mixing chamber of the first drum.
13. The coater of claim 11 wherein the second drum includes at least twice the capacity of the first drum.
14. The coater of claim 11 further comprising:
a plurality of baffles positioned within the first drum, the plurality of baffles adjustable from outside of the housing.
15. A coater for coating a material with a solution or a suspension, the coater comprising:
a housing;
a drum positioned to rotate within the housing and removably attached within the housing, the drum having an annular flange positioned at an access end aligned toward a front of the housing and a drive end positioned opposite to the access end;
a cradle positioned under the drum, wherein the cradle facilitates removal and replacement of the drum with a replacement drum having a different size, the cradle including a slot to support the drive end of the drum;
a dolly slideably engageable with the cradle for removal and support of the cradle from the housing, the dolly including a plurality of wheels to permit the dolly to slide in and out of the housing;
