200L Commercial Pressure Sterilizer – Digital Electric Mushroom Autoclave
Commercial Capacity • Digital Controls • 220/240V Electric • Built for Grain Spawn, Substrate & Lab Sterilization
Scale your mushroom production with our 200L Commercial Pressure Sterilizer, a digital electric mushroom autoclave designed for serious growers, labs, and small-to-medium commercial farms. With a compact vertical footprint and true commercial-grade capacity, this unit helps sterilize grain spawn bags, substrate bags, agar supplies, tools, jars, and other cultivation materials with consistency and confidence.
Part of our Professional Series, this 200L vertical autoclave offers the capacity of a commercial sterilizer while taking up only about 29" x 29" x 51" of floor space. It features digital control over cook cycles, temperature, pressure, and timing, making it a dependable “set it and forget it” machine for daily production.
Choosing the Right Commercial Autoclave
Watch this quick overview to compare autoclave sizes, production capacity, and which model may be the best fit for your mushroom operation.
If you're comparing sterilizer sizes, the 200L commercial autoclave is a popular mid-scale option. It offers significantly more capacity than smaller sterilizers while still fitting through standard doors and working well in garages, labs, grow rooms, and small production spaces.
- Great step-up model for growers scaling beyond pressure cookers
- Higher capacity for grain spawn, substrate, jars, and lab prep
- More efficient production compared to running multiple small sterilizers
Why Choose the 200L Commercial Autoclave?
- Commercial-Scale Capacity – Holds up to approximately 72 three-pound grain bags or 40 five-pound bags, depending on bag size and layout.
- Digital Set-It-and-Forget-It Controls – Adjustable temperature, pressure, and timer settings simplify repeat sterilization cycles.
- Compact Vertical Footprint – Large internal capacity while taking up only about 29" x 29" x 51" of space.
- Built for Mushroom Production – Ideal for grain spawn bags, substrate bags, agar prep, jars, tools, and lab supplies.
- SUS 304 Stainless Steel Chamber – Durable internal construction designed for commercial use.
- Manual & Automatic Venting Options – Choose the cooling and venting method that best fits your workflow.
- Safety-Focused Design – Includes a safety-locking lid, water level sensor, automatic shutoff, and over-pressure bleed valve.

- Professional installation recommended
- Color-coded wiring can be configured for the outlet type selected by your electrician
Common Uses
- Sterilizing grain spawn bags
- Sterilizing substrate bags
- Preparing agar media and lab supplies
- Sterilizing jars, tools, and reusable equipment
- Pasteurization workflows when lower temperatures are desired
- Small farm and commercial mushroom production
200L vs. Smaller Sterilizers
For growers using pressure cookers or smaller autoclaves, the 200L model can dramatically increase output per cycle. Instead of running multiple small batches, you can consolidate production into fewer larger cycles, saving labor and improving workflow consistency.
- More capacity per run than tabletop or pressure cooker setups
- Better workflow efficiency for farms producing grain spawn or substrate regularly
- Still compact enough for garages, grow rooms, and small production facilities
- Ideal bridge model before moving into larger commercial systems

So far it seems very sturdy and I will give another review after I fill her up. Im just getting started with this life changing hobby and this will hold up strong
It was a price commitment, however it equated to less than I would spend on most any DIY project. I decided to purchase it and have since done spore work, agar transfers to agar and grain, culture to spawn bag inoculations, cloming and prints all with a 0% contamination rate. I practice about as good a sterile technique as I can mustard, considering I perform all my work on my kitchen table. Im consistently amazed by how flawless everything has turned out since adding this to my operations. I consider it indispensable. Instead of the double sided tape provided, i purchased some plastic velcro tape from the Gnome Depot and use it to affix the pvc guards to the sides. When i am done, i have also made it so i can sandwich them together and store them one the front to protect that precious filter when not in use. If you can swing it, buy it. Takes the risk out of procedure. Im bummed i cheaped out on the stainless riser offered at a discount with purchase of the LFH. That would have been exceedingly useful, but I have since utilized a baking drying rack to much success. Now go forth and frolic in the dung!
This is really built well, simple to operate, so happy to have some control of fruiting conditions finally.
I ordered 7 altogether so far, and every single one worked faster than expected. As you can see from the pics I got crazy growth in just 5 days from all of them!
I absolutely love the 28 quart monotubs. It lets me have 2 different grows going and since I'm a beginner, that helps in case one tub get contaminated or something goes wrong with one. I will still have a backup! Happy Growing! I know I am!
So far, I have no complaints. Everything was delivered on time packaged with care. I got everything set up now, i'm just crossing my fingers and hoping everything crosses the finish line.
10 pounds black cow casing, 3-32oz 5 grain jars fully colonized in mono-tub. Completely covered with mycelium and started fruiting condition on day 7.
Very happy with my purchase of Milo. Would recommend to anyone who is interested in making their own grain spawn.
The coco husk is perfect and it's a good price
Thanks for the amazing products and Great Service! Always my go to vendor for grain and substrate
Last week I got the brick to test drive for my microgreens, after using Fox Farm for over 3.5 years. As the rising costs of soil, the weight, the shipping cost and the covering per bag, we needed to find something else. After a couple of days searching I found the bricks from Midwest. I send an email to be sure that I can use it for my greens, signed up for subscription as it saved me 10 bucks and ordered a pack of 4. If it doesn't work well so it be, for 66 bucks, 120 bucks cheaper than the soil, there's not much to loose.
I was anxious, as I never used anything else than soil, your always be careful when changing to a different product.
Used 1 brick with water and was blown away immidiatly as I actually was getting almost 28 gallons of soil from 1 brick, astonishing. Okay now we plant and see if it's working and dam, I'm impressed!!! Greens came up 2 days faster than expected, the soil is the best i've got in years, they water intake is amazing as it holds it much longer than soil. The greens looked great and taste perfectly.
I counted that a pallet of 220 bricks for $1724 incl. shipping, could give me roughly estimated 26 gallon per brick, 5720 gallons which is 764cu.ft, I would need to buy 382 bags of soil to get the same amount of soil comparing to the bricks, I would need to order 8 pallets of soil which ends up incl. shipping at $17236,80 (shipping per pallet at $861). Considering that I get an awesome product that works 10 times better than soil, I also safe $15512,80 that I can invest in my company. I'm sold. The future looks brighter than ever as i stick with the bricks!!
I order everything here first so needless to say… but well deserved…
This company hands down is for mycology and the people!! I bet you bottom dollar I’ll order something or rather from Midwest within the week or 2🤑
WORKS WELL IM IMPRESSED THANK YOU MIDWEST YOIR THE BEST !!!!!☝️
Works great 👍
