Abstract
Thesis The design and construction of a feed mixer was intended to Design and build a feed mixer To study raw material variables that affect the production process and machine performance to improve feed mixing for the community and is a role model for small and medium-sized farmers.
The operation of the feed mixer is equipped with a horizontal mixing tank in which the body can be rotated to compress. The diameter of the tank is 60 centimeters, length 93 centimeters. Inside the tank are welded creeps attached with the inside of the mixing tank to use to stir the ingredients without letting the ingredients sit at the bottom of the tank The power unit is used to drive the mixer tank, it uses a 1/3 hp 220 volt motor and a 1 hp 220 volt motor drives the agitator. The experimental procedure was performed using the agitator rotation speed of 40 and 60 revolutions per minute to determine the production rate. and suitable humidity for mixing.
The results of the feed mixer experiment can be seen that as the rotation speed of the agitator increases Will cause humidity and time to decrease, resulting in a trend of increasing feed mixing rate. which formulas 2 and 3 can be mixed with the most suitable quality.Production rate 300 kg/h, humidity 14 percent, speed 60 rpm, with break-even point, pig feed pellet machine. Must be produced at 65 days, which will cost 217829.3 baht.
