The book series I am thinking of featured a family of mother, father and two brothers living on a fairly ramshackle spaceship, each book was about 150-200 pages long, aimed probably at the 9-12 age group and was available in the UK.
The series premise was that the family travelled around doing odd jobs, but of course something always intervened and turned into the main plot point. The space ship was in bad state of repair; and most of the technology on board was dated by the standards of the time and constantly breaking.
They did have a food replicator which 'created' food based on the thoughts of the operator, again this didn't work very well and most often the flavour or texture was off. At one point one of the boys thinks really hard and tries to make roast dinner (?) but all that happens is that for weeks afterwards every food created by the replicator is a cross between the operators thoughts plus some component of the dinner (peas were mentioned ISTR).
