Optimizing agricultural (gleba) science freshness

Post by inefficient »

Hey folks,

Be ready for some fresh agricultural science from gleba!

I build this little contraption to make around 90 agricultural science per s on Nauvis in my setup (that is 2.7 science packs per second on gleba). To make sure I get there as cheap as possible, I needed the freshest gleba science possible. I manage to get the freshness to >97% in this setup with some packs having >98% that is 59 mins before spoilage! In my setup the key determinants for freshness are how long the fruits remain on the conveyor until delivered to my base and how long it takes to process the jelly and mush. Both jelly and mush have short spoilage timers so being quick here is imperative. The other components are a bit more forgiving. I had this running for an hour or so and no issues. I also want to point out it is extraordinary cheap to restart! You only need 25 nutrients and 1 egg :)

The machine has a lot of combinators that continuously monitor the item flux through the rocket silo, measure the flow rate of fruits on the conveyor belt and adjust them to a roughly constant level, but also a fail safe mechanism. If it ever were to stall, fret not, I got you. The factory will empty itself and put the leftover eggs into a box. This triggers an emergency signal and also tells you there is something wrong. You can use the eggs to restart the machine. But even in case they pop because you were busy somewhere else, there are some walls that contain the aliens. It also fully self-sustaining, making rocket fuel to power the entire contraption. There is some backup energy that fuels a few inserters to restart the factory after a complete shutdown and loss of temperature in the heating tower. Just flip the power switch and they will start rebooting it using backup rocket fuel. There is a combinator with some info sign that gives instruction for the restart.

How to use it:
1. Place the BP
2. Flip the orientation of the inserters that load the science pack biolabs towards the rocket silo so that they dont take eggs before production has taken off.
2. Flip the power switch and add some 60 rocket fuel into the lower wooden chest near the rocket silo that has two inserters next to it with rocket fuel filters set. Wait a minute or so and connect water somewhere.
3. Toggle the constant combinator with the S near the agricultural science buildings on. This resets the stalling timer and temporarily disables it.
4. You have to add rather timely 5 nutrients into biolabs making jelly, mush, bioflux and nutrients, and 1 egg into a egg biolab.
5. Once all 4 egg biolabs are running, flip the inserters of the science pack bioloabs back so that they start loading the labs and turn of the S combinator so that it can detect stalling.

In case of stalling:
1. again flip inserters for science packs and the S combinator.
2. add nutrients and 1 egg.
3. wait until all egg biolabs make eggs, flip inserters back and here we go!

In the beginning its a bit slower because it has to fill all the chest with rocket fuel but once this is done, there is more bioflux available for science.

Also, you can build this after visiting vulcanus, I need one green underground belt in the setup. All other materials are available as soon as you have yellow/purp science. There is a workaround to get rid of it but it bloats, up to you if you want to do that. But then you could go straight to gleba.
