150L Commercial Pressure Sterilizer - Digital Electric Mushroom Autoclave

Our Professional 150L (160 Quart) Mushroom Autoclave is the industry standard for high-capacity sterilization—trusted by top labs and mushroom farms for over 15 years. Compact enough to fit in the footprint of a small bar fridge, yet powerful enough to process up to 48 grain bags per cycle, this unit is known as the workhorse of the industry.

With digital precision controls for temperature, pressure, and time, it’s a true set-it-and-forget-it sterilizer. Simply load your grain or substrate, set your PSI and cycle time, and press start. The autoclave takes care of the rest—ensuring consistent, repeatable results every time.

Frequently Asked Questions

Q: How hard is it to install?
A: Installation is straightforward—similar to adding a dryer outlet. Most electricians can wire it quickly.

Q: What’s the process for sterilizing grain bags?
A: Add 4–4.5 gallons of RO or filtered water, load the grain bags, secure the lid clamps, and start your cycle. For a full load, we recommend 121°C for 3.5 hours.

Q: How long does a cycle take?
A: On average, 4–4.5 hours including heat-up and cool-down. You can choose natural cooling (3–4 hrs) or computerized venting (15–25 mins) for faster turnaround.

Q: How much can I sterilize at once?
A: Up to 48 x 3 lb grain bags or about 140 lbs of substrate. Removing baskets allows slightly more capacity.

Q: Why buy from us instead of competitors?
A: Unlike many sellers shipping overseas units with 8–12 week wait times, we stock in the U.S. for fast delivery, provide in-house technical support, and offer custom factory upgrades to ensure reliability and bag-safe performance.
