(The mod name have changed to Cold Chain Logistics, because now we have local store, cross planet space transport, local planet railway transport, and distination warehouse storage. And I think we can proudly announce that, we have the full supply chain updated with refrigeration support.)

Having produced agricultural science pack spoiled?
No worries! This mod can cover you up!

• Adds a fridge chest that slows down the spoil time of items inside it by 20 times. Now you can set your own freeze speed. ranged from 1 to 100.
• Adds receive, passive and buffer logistic fridge
• Adds a big freezing warehouse for late game research, more specifically, after you have cryogenic science pack unlocked. (graphics not ready yet, just using same icon but larger size..) Graphics now ready!
• space cargo bay that adds extra slots into main hub that can freeze item in it.
• cargo train with same function

(if you curious why it need a uranium-fuel-cell, well technically a fridge need power to operate, but a container prototype don't have any energy options. and if i want to use other prototypes that has energy inputs then it doesn't have large enough storage space. I can't find a way to "fuse" two prototypes together. and another approach is to create a hidden entity that takes energy and controls fridge function based on whether connected to electricity. but this is complicated and may cause bugs, and I don't have time for that, so I just takes an uranium-fuel-cell and says somehow it managed to make a Nuclear powered refrigerator that don't need to connect to electricity then. Now big warehouse is using this "fake power cord". To keep it simple, I remains small fridge unchanged )

P.S.
I am busy studying, so I don't have much time to work on this mod. but I am happy to review and merge others' pull requests. so feel free to contribute to this mod. source code here

TODOs:
- Add fridge in space platform Done
- Add refrigerated train car Done
- Add settings for configure how slow the spoil time is. Done
- Add a freezer entity that stops the spoil time completely. (this need some balance, such as item in the freezer need to be defrosted until it can be used) Done
- Adjust technology tree make it reasonable, such as can only be researched after you landed on the frozen planet. Done
- Adds fancier graphics for fridge and freezer. Done on freezer
- Adds bigger capacity for fridge and freezer. Done, now adjustable in the settings
- Adds temperature system, such that the spoil rate is affected by temperature.
