What Happens When You Grind Dry Florals or Herbs?

Being able to manufacture our three roll mills and have our lab next door has been a great resource for testing, not only for us but customers. Recently we had a customer to come in and test a dried herb that was quite oily and sticky when processed - they wanted to see how the mill would be able to handle different herbs and how it compared to other machines. As this customer was testing on the mill they asked us how it would be able to handle different items from lavender to tomato seeds just to name a few. We knew it could pass those products based on past tests that we had ran on other products, but had never actually tested them ourselves. That is how we started the poppy seed test and lavender test. First to see how each product handled going through the mill dry and how it handled after being paired with something that would make it saturated.

The first lesson that we learned in processing was that poppyseeds handle being dry much better than lavender due to the natural oils they produce. They were able to pass through both the front and back gap without a problem because they stuck to each other and during its pass, ground down to a pigment like consistency. Whereas the dried out lavender was able to pass through the machine without a problem but it would fall sometimes in between the back gap because it didn't always have enough natural oils to hold itself together throughout the entire milling process. We never had to add any other products to the poppy seeds since they were able to pass without any extra product to hold them together. However the lavender while it was being finely ground, it wasn't the best technique since some of it was falling through the back gap, so we added a bit of petroleum jelly to see how fine we could make the pieces and see if we could make it smooth enough to add into a cream which we achieved with no problem.
