It seems like the pipe on the cryo generator isn't pointing into anything. The cryo generator cools down the structure it is connected to, and it is connected when its pipe (the yellow thing sticking out to the left of the cryo generator in your screenshot) is touching the structure. You should move the cryo generator so that its pipe is right up against the freezer chamber, other than that the setup looks good.
Yeah I would do what kurrosity said. You should have the cooling fan adjacent to the building. You have to ctrl+click (i'm not sure if this is correct, it's been a few months since i've played) the inspector panel for it to work properly (foods have a certain temperature range where they can be created in, if it's too low or too high the food isn't made).
If you still need help just lmk and I'll redownload the game and send you more instructions. Like I said, it's been a hot minute since I've played Gain Factory so sorry if my instructions were ass
