My tempeh incubator setup

Postby curtijam on Sat Jun 08, 2019 7:03 am

Hello fermentors,

New here and thought I'd share my incubator setup. I found a thermostatic bar heater on Amazon, and purchased this along with a digital thermometer (to test how accurate the heater was, and monitor the temperature) and a wire rack to keep the tempeh of the heater. I then stuck all of this inside a soft insulated picnic hamper which we already had, and used some drinking glasses to balance the rack on.

I spent an evening fiddling around with the thermostat on the heater trying to find the perfect temperature, and discovered there is a large gap of around 17 degrees centigrade between the high temperature where it cuts out, and the low temperature when it starts up again. So it's not very precise! In the end I found a setting where the maximum temperature didn't go above 35degC and made a reference mark with a Sharpie so I could easily find the same setting every time.

Quick and fairly cheap setup (~£50), but does the job and makes great tempeh!

What's your setup?

Jamie

and here are some pics of the finished tempeh! The first one was plain Soy bean, which was a bit under-fermented and crumbly. Second and third I started playing around with other beans and chickpeas, and let them ferment for a bit longer in the incubator.

Nice Cerbu - looks like I could have saved myself a few quid if I knew more about electronics!!! :)

I consider your tempeh to be poor quality. The beans should not be obvious, meaning they should be consumed by the mycelium. The cake should be homogeneous IMO. This is more than fermentation time. Look at some of my posts.

After an internet perusal of the presented fermenters or incubators it was decided to make a simple unit from common readily available parts. The parts are: A 23 liter bucket from home brewing wine store, a muscle heating pad wet/dry with Low, Med, High switch from a pharmacy about 14 by 11 inches, a 20 watt LED with a dimmer switch from a local hardware to fine control the temperature at 31C, a trouble lamp socket with cord for the dimmable LED bulb, A simple stand from shelving area of a hardware store to set the trays on, a cheap bulb thermometer. The only tool required is a soldering iron to burn a hole in the lid of the 23 liter bucket to install the dimmable LED. Construction should take only a few minutes after acquiring the parts.
