Bag Tumbler

Unicorn Mushroom Bag Tumbler
For best results with your spawn run, it is necessary to fully mix the spawn with the substrate after it is sealed in the bag.  Shaking the bag by hand helps, but does not fully do the job.  Some mechanical shakers can damage the bags and lead to contamination.  We have developed a double axis tumbler that safely and completely mixes the spawn with the substrate to insure a fast spawn run. This mushroom industry specific rotating tumble mixer uses custom and proprietary trademarked technologies to achieve a consistent single pass bi-directional or bi-axial mixing motion of the contents of spawn inoculated substrate bags.
Bag tumblers are available only by special order.  Please contact us to place your order.
