Posted: Tue Sep 04, 2018 6:17 pmSteeping Grain
The moisture content of barley is increased from 12-13% to 42-46% required for germination.
Steeping has two components, west steeping and air rests.
Steeped in cool water for eight hours. Drained off and air rested for eight hours.
Steeped again for two hours. Drained off and air rested for eight hours.
Continue this until small roots start to grow. (call chits)
So the barley is Chitted.
I use two bins the small one has holes drilled and the large one hold the water. So drying is lifting the
small bin up and let it drain for resting period. Renew water each time you steep.
I also use a small aquarium pump to push air into the water.
There is plenty of info floating about on the Web.
Malting Machine
An old front loader washing machine.(whirlpool AWM 312/3) With a dryer motor on top and pulleys to gear down the speed to 18 rpm using two small bicyle wheel at the back.
Germination of grain at 18 deg with moisture. 2 to 5 days
A pressure sprayer keeps the grain moist and the motor and drum are controlled by the Sansui timer and rotates 5 minutes every 1 hr 12 minutes and the inkbird timer controls a water value which sprays water for 5 seconds and a small blower fan on the right hand side for air circulation
The 240 Volt Sansui is a 20 program timer.
I use a turbo oven for temperature to keep the temperature to 18 deg. This is controlled by an STC
Drying and Kiln.
When the acrospire is 3/4 length. The turbo oven is set on 40 deg for 24hrs and 60 deg for 12 hours. to dry and than at 80 deg for 3 to 5 hours to kiln.
Need to test for moisture content, so those times are approximate.
The STC controller is powered direct from the 240 volt power. The temperature is set to whatever is required and the turbo oven and the motor to turn the drum is now plugged into the STC controller which switches on and off as the required when temperature is reached.
The temperature probe is through the door into the malt. Had to put a stiff piece of wire along the probe to keep it in the malt,.
When drying and Kiln, water spray is not needed.
Once a day I pressurize the sprayer to 30psi and I need to keep an eye on the temperature. It doesn’t use much water, about 2 litres a day maximum. Its call a halogon turbo oven and draws 1200 watts, but it is very efficient. Yes it has a fan that forces air into the washer.
Note the STC is a Lilytech ZL-6230A+ with and output of 30A
