Okay, I finally got around to making the Vacuum Freezer. First of all, I really don't like Tech Reborn. Incomplete buggy nonsense. For example, if you use the TR Wrench to break the Vacuum Freezer machine, it becomes a different machine. Super annoying, especially because you apparently need a 3x3 multiblock connected to the Vacuum Freezer, but there is no info on where the Vacuum Freezer attaches to it.
Also, despite the note in Age 10 of Guide, the Vacuum Freezer does NOT need Ice Shards as fuel. As someone on the Discord pointed out, the recipe still needs one single Ice Shard. But that's it. You don't need any more than one Ice Shard. Hope you didn't get into bees just for that.
EDITED to show you still need one Ice Shard.
