Oyster Mushroom Straw Substrate Pasteurizer/Cooker and Bagger Equipment.

Description

Semi automatic, Oyster mushroom substrate processing equipment.
Custom built, and used system for 2 years. It is design so 1 person can do the substrate processing for oyster mushrooms.
Here is an overview of the this setup’s process.
Finely chopped straw is added to the mixer via a hatch door on top.
Water is added to straw till desired moisture content is reached.
The steam cycle is started. The following is the automatic cycle.
Boiler starts.
The target pasteurize temperature is reached and maintained for the set amount of time.
System switches to cool mode and is vented till cool target temperature is reached.
System stops.
Spawn is added and mixed.
Put bag on end of bagger.
Unload mixer into bag packer.
What is included:
Insulated mixer.
Propane steam boiler.
Bag packer.
Bag cart.
This system produces 12 inch diameter bags, up to 7 feet long.
Three small straw bales would produce 2 columns approximately 6 feet long, weighing 150lb each.
I used this system twice a week, producing 4 columns a week which produced about 120lbs of fresh mushrooms a week.
Usually I would start this system in the evening, it would run it’s cycle overnight and be ready for bagging in the morning.
Filling the mixer with straw and prepping took about 30 minutes. Bagging and cleanup took about 1 hour.
