here's another build I just did using kekimurus...
kekimurus eat cake that's placed down into the world and produce mana. it can actually be quite difficult to automatically place down a cake.
sure, you could use a golem, but I don't really like to use golems in automated builds.
in the end I found out that a block placer from OpenBlocks is able to properly place down a cake, and using that block I was able to make this build.
it starts out with a simple 3x3 farm made with crops from agricraft. 3 crops are wheat, 3 are sugarcane and 3 are soybeans.
their growth is boosted using the sprinklers from agricraft, and the crops are harvested using a harvester from MFR.
the output is send to 3 barrels.
from the barrels I'm using Steve's Factory Manager to craft cheesecake from pam's harvestcraft, which can actually be placed down into the world and kekimurus can gobble them.
I chose the cheesecake because it's such an easy recipe to do. I use SFM to craft both the sugar and flour, but for the silk and firm tofu I need to use the presser from pam's harvestcraft.
the presser's are actually the part of the build that slows things down, so if you want to speed things up, use more presser's.
as you can see I'm using 3 pressers, one for soybean > soy milk, one for soy milk > silk tofu and the last is silk tofu > firm tofu.
as soon as all the required components are gathered into the chest, a cheesecake gets crafted and the output is send to the barrel.
from that barrel 1 cheesecake is send each time to the culinairy generator from Extra Utilities to provide RF that's needed for the harvester.
the other cheesecakes are send to the openblock's block placer if there's more then 16 cheesecakes in the barrel.
lastly a redstone pulse is provided to the block placer if there's more then 1 cheesecake in the block placer, which causes the cheesecake to be placed down so the kekimurus can gobble them up.
any producded mana is send to a mana pool using a gaia spreader because the kekimurus can actually produce quite some mana.
lastly, if the pool is full a comparator will send out a redstone signal which will stop the block placer from placing down more cheesecakes.
the build can be done much bigger then this, but as mentioned the problem lies with the presser's that are quite slow, so if you are planning on making this build bigger by using more kekimurus, also add more presser's to the build.
