Unless you are in a heatwave which can cause real evaporation the usual reason for a worm bin failing to produce liquid is that there isn’t the volume of waste going into the kit in the first place. Over 95% of veg waste is liquid so as long as plenty is going into the kit as it breaks down the liquid will percolate through the worm casts and end up in the sump where you can use it diluted (about 1 part liquid to 10 parts water) as a general liquid feed.
