salivary glands
The primary mixing or churning organ in the human body is the stomach. It is responsible for breaking down food into smaller particles and mixing it with gastric juices to form a semi-solid mixture called chyme. The muscle contractions in the stomach wall help to churn and mix the food, aiding in digestion.
The salivary glands create enzymes that aid in the initial mixing with food and breaking it down into particles.
Brownian motion is the random moving and mixing of particles.

Fruit Juices are considered mixtures because when mixing two or more juices no chemical reactions take place, so they can not be called compounds etc.

Particles with very small dimensions - easy mixing; big dimensions - slow mixing and also uncomplete.
they are concealed
in solid mixing solid particles are mixed randomly but in liquid mixing the liquid droplets are mixed as homogeneously.
