Yeast Propagation Tools

To help grow viable yeast before pitching, I built a stir plate. The first model I made turned out to be underpowered and so with this one, I went with a larger motor and clear acrylic so that I could spot what was going on if there was a problem.


The dial on the right allows us to adjust the motor so we get the perfect speed depending on yeast starter size.

Although this is just water, the stir plate allows more oxygen into the yeast starter. This, combined with the fact that it also keeps the yeast in suspension, helps to grow larger and healthier quantities of yeast which in the end help to produce a better fermentation.

  1. The Heated Blanket nozzle has not been regularly cleaned and construct up has occurred. Brittle filament, breaking or snapping could mean stale filament. There are additionally some of the the} more brittle formulation, particularly for PLA or PMMA, which could snap when passing the drive gear or is bent for instance in a Bowden tube at a better angle. Filament will take up moisture, Nylons and PVA particularly, but may possibly} additionally occur with ‘normal’ filament, even PLA, it just takes longer. Make positive you retailer your filament in sealed luggage with freshly charged desiccant. The identical half of} filament is getting retracted, pushed forward, retracted multiple of} occasions.
