Method and apparatus is described for producing bee wax particles to be used in pharmaceutical or cosmetics industry. Molten wax is fed from the top of an upright column downwards, against a counterflow of a cooling air whereby the molten wax solidifies into small particles. The method and the apparatus include provision for controlling and/or monitoring the following variables: (i) the velocity of cooling air flowing through the column; (ii) the temperature of cooling air at its entering into the column; (iii) the temperature of air discharged from the column; (iv) the temperature of the wax at its entrance into the column.
