My sister is looking for a juicer to buy my mother who makes gallons of tomato juice each year by manually pushing the tomatoes through a colander . I have the Kitchen Aid fruit and vegetable strainer attachment that works with the food grinder attachment and used it years ago to make tomato juice but can't remember if it does a good job. I have the impression that many of today's juicers aren't meant to be used for such high volume jobs. Does anyone have any suggestions or experiences using a juicer to make a lot of juice? Thanks.
