translator doesn't determine the grammar I eat rice = 我 吃 米饭。 = wǒ chī mǐ-fàn.

Do not use online translators for Chinese. The sentence it has given you is nonsense. If you want to say you are eating rice (at this moment) you can say 我在吃米饭. If you just want to say you like eating rice, you can say 我喜欢吃米饭.
