Hello guys!
Pls, help me with my DIY winnower, I'm stuck in nowhere after several of iterations of making the winnower.
Pls, check the photos here: telegra.ph/My-winnower-11-01
Initially, I made it exactly according to your drawing - with a 3" drop tube and other tubes were 2", but the bucket was 10 gallons instead of 6. My 1800 watt cyclone Hitachi vacuum cleaner couldn't suck most of the husk, so I rented professional one with 2 engines 1200+1200 watts. As I got from a comparison of Shop-Vac US and world models 6.5 hp = 1800 watts, so 2400 was definitely enough. But, again, no luck. I even tried to reduce the volume of the bucket to 2/3 or 3/4 putting its cut cover to the bottom part, again - most of the husk wasn't sucked. Another thing - I used Crankenstein mill, which made very uneven nibs and husk, so I thought the prob could be related to big husk parts (which wasn't sucked) and small nibs (which was sucked).
So I ordered second-hand Champion and in the same tame changed 3" tubes to 2". My cleaner still couldn't suck anything at all, so when I got Champion, I rented the same 1200+1200 watts pro-cleaner and started to experiment.
That iteration was good: cleaner was sucking husk and nibs, in different proportions depends on valves settings. I even could get almost 100% clear nibs, but when I started to measure weight - it was only 50% of all nibs/husk.
After 1,5 days of playing with settings, I got such thing: I can do 50% of clear nibs or even 60% of almost clear nibs. Or I can get 80%-85% of nibs but they will be not clear at all. I drew some scale on valves, and I got 50% at one point of scale of the valve which is on top of the bucket, and 80%-85% at the next point. I tried to set a valve to some neutral position between these 2 points of the scale but got the result close to 50% or 80%. Looks like I couldn't get any results between these 2 results (50% and 80%)!
And the valve, which is close to the deflector almost didn't affect the result - the number of nibs in the bucket almost not correlate with the position of the valve, it jumps chaotically. So I couldn't make any less waist of nibs at 50% or 80%.
I tried with no luck:
- to use 1200 w and 2400 w of vacuum (1 or 2 engines)
- to decrease the volume of the bucket from 10 to 7.4 gallons
- to grind off a bit of deflector
Also, I had some idea that maybe beans not roasted enough. But my wife roasts them and do hairdryer winnowing, it's works fine and she getting 85% of nibs, and also I was reading that your Sylph possible to use even for the raw nibs.
Pls, give me some advice on what to do to make it work? I'm trying to make my wife work process easier but spent time, money and have no idea where to go.
