Automatic Vibrating Sifter - Commercial 15.50 x 4" Sifting your plant material is an excellent way to remove stems automatically. This commercial sifting machine was explicitly designed with processors in mind - the stainless steel construction and screens ensure you can easily clean our sifter, and the screen sizes are fine-tuned for the most common sifting needs. The commercial grade sifter offers a larger diameter, coming in at 15.50 inches, compared to the 11.75 inches of the original starter sifter - this means you'll be able to sift more plants in one sitting! Once you've ground your plant material, you only need to pour it into the sifter and switch it on. You can now walk away and wait for your plants to be automatically sifted - no more standing around doing manual sifting. Sifting your biomass will not only ensure no stems make it into your final product but will also ensure nothing else makes it into your product, like large leaves, gravel, or any other foreign matter. Additionally, consistent grinding will make your product burn more evenly and pack more evenly in any cone-filling machine. (Compare to Custom Cones) Plant Material Specific Sifter The commercial sifter was explicitly designed for plant material processors. From its stainless steel construction to multiple screen sizes, our team of Experts is confident this sifter or our other larger sizes will be the perfect addition to your product production process. We offer multiple screen sizes, allowing you to customize the particle size for the plant material in your product. Depending on the strain or weight of the product you are making, you may want to experiment with various screen sizes. Multiple Screen Sizes When it comes to sifting your plant material, you will want to have an ideal particle size for your plant material in mind. If you are still determining what size screen you need, our team of Experts is here to help! Depending on your strain and grinder, your ground biomass will have a different consistency. Additionally, depending on the size of the cone you are using and your desired fill weight, the particle size of your plant material will play a significant role. For example, a smaller particle size will allow you to pack more plant material into a small cone, but a particle size that is too small may lead to a poor, uneven burn.
