Seed Processing and Cleaning Equipment

Large amounts of seed need to be collected each year to grow native plants for Mt Chocolate.

With 220 different species to grow and plant, getting the right seed and germinating it can be quite a process.

Seed Processing Steps

  • Collection from the right plant during the right month
  • Drying the collected material
  • Separate the seed from husks, stalks and leafs
  • Washing and or cleaning the seed
  • Fermenting fruit mash for 3 days to kill bacteria and fungi at 20-24 C
  • Separate by washing and or cleaning
  • Drying again to a low moisture content
  • Storage in a container at the correct temperature and humidity

Seed Treatment Steps (possible)

  • Soak in water
  • Freeze
  • Heat up
  • Scarify hard seed coats eg Kowhai

Seed Sowing

  • Sow in seed trays and grow pots under cover.
  • Watch for seedlings last week of September.

Equipment

So after doing this for a few years, I wondered if there was a way to make and use simple DIY equipment to help with seed processing. It turns out there is a way. Large commercial nurseries and crop farmers may process their own seed using specialist equipment which costs a bit.

Searching on Google, there are loads of small scale things you can make in a home workshop that will do the same job. I'm going to have a go. Below are links and videos to some of the stuff I found.



  • Realseeds (has plans for these air separating seed cleaners).
  • Kimseed (specialises in great equipment for labs and revegetation projects in Oz).
