Food machine

The Food Machine was a device in TARDISes which created flavoured pills and water for consumption.

The Doctor used the food machine to feed Barbara and Ian Chesterton, giving them pills that tasted like a bacon and eggs breakfast. (DW: An Unearthly Child)

Ace was later able to make the food machine produce actual food. (NA: Legacy)

Later, the Doctor attempted to fix the machine, which had not been used in years. He was unable to do so, giving food pills with disgusting mixes of flavours. He was later able to uses these food pills to kill the Glutonoid, when he fed him a fatal mixture. (DWBIT: The Glutonoid Menace)
