Chicken plucker biuld

Very nicely done, rasorbackq! Welcome to the popped breaker club.

Could you please post some photos of the plate inside the drum and maybe some info on where you got your gear reduction from?

Gear reduction is simply done with a belt and pulley.

Question for those that have done more chickens than me. How long do you scald them before throwing them in the plucker? I did a small batch last fall with a plucker I built, but had a lot of skin tearing. We would scald until the wing feather pulled out without much effort, but I think that was too long. I do need more fingers on the plate to help hold the bird up, but I also think we scalded them too long.

On my 3rd chicken plucker build . The last 2 have been a Whiz bang plucker style . This one is larger with a 30 " spinning plucker plate for doing turkeys better.


So my question is plucker picking plate should spin at 172 RPM and with a 1725 RPM motor to a 10:1 gear reducer the math adds up. But this seems to spin very fast !!.
My question is with this set up will a plucker plate that is 10" 20" or 30 all spin at 172 RPM at the outside edge?? Or does some how as diameter increase so does the speed?
Never took all that stuff in school and my math skills are not up to par

Tried the net but didn't know what to type in as a search.
Someone here will have the answer .

You didn't put the gear reduction on backwards to make it 1:10 by chance? That would give you 17,250 RPM! :laughing: Turbo Turkeys! :laughing:

Some rough calculations:

A 30" feather plate has a circumference (pi times diameter) of 94.2 inches

At 172 rpm the rim is traveling at 22.5 feet per second or 15MPH. 172x94= 16168 inches per minute. 16168/12=1347 feet per minute. 1347/60=22.5 FPS or 15MPH (all numbers rounded)

Using the same numbers for a 24" plate gives about 12.25MPH

To get the same rim speed from a 30" plate as you get from a 24" plate, you'd need a shaft RPM of about 138.

On a 1725 motor that'd be a reduction of 12.5 to 1.

Based on one season's experience with my home-built Whizbang, I need to slow my feather plate down too.

Princess Auto in Canada. This reduction system is great as it comes apart to move the I/P and O/P shafts from top to bottom or left and right depending on direction and how its going to be mounted. The plate is 3/16 The 3/4 shaft is welded to a 1/4 x 3 x 6 plate and bolted to the plate. The extra 4 holes were drilled with a hole saw and are slightly big to hold the fingers.
I will get some electrical box knock outs and plug them.

No belts on this one Direct drive gear reduction.

Scalding water temp is 147F for 1 min.

Much more and you can sell skinless poultry

The book .......Anyone Can build a Tub style Mechanical Chicken plucker (Only book I ever bought and read cover to cover . I hate reading books) says the rpm can be 150-300.. Since the gear reducer only comes in ratios of 10, 30 and 60:1 how can I slow it down. I have a variact transformer but not wanting to kill the motor.

My gear reduction is 10:1 already

One way that comes readily to mind is to add a jackshaft between the motor and the gearbox or between the gearbox and the shaft on the feather plate. As noted elsewhere, you can then use a belt and pulley setup to provide reduction. This would require the most fabrication but be by far the cheapest.

Option 2 would be a faster motor (3450 RPM) and deeper reduction (30:1) giving a shaft speed of 115RPM. Easiest to build but probably most expensive.

Option 3 a gear reduction motor driving your existing gear reduction unit. Gear reduction motors are available in a variety of options from places like Surplus Center.
