Method and plant for obtaining a ready-to-use food product based on rice germ

A method for obtaining a ready-to-use food product based on rice bud, comprising the steps of:

• providing a certain quantity of rice bud;
• subjecting said quantity of rice bud to a radio-frequency drying treatment;
• and
• packaging at least part of said quantity of dried rice bud;
• wherein the step of providing a certain quantity of rice bud comprises the steps of:
• providing a certain quantity of husked rice or paddy rice;
• and
• separating rice buds from rice grains of the husked rice so as to obtain the certain quantity of rice bud with a purity of more than 70% by weight and wherein the radio-frequency drying step occurs within 24 hours of the separating step of the rice buds from the rice grains of the husked rice;
• and
• wherein the step of separating the rice buds from the rice grains comprises the steps of:
• subjecting the husked rice to a first separation treatment by means of a pneumatic cyclone in order to obtain separation between heavier material falling to a bottom of the cyclone and lighter material evacuated upwards;
• subjecting the heavier material exiting the cyclone to a treatment by plansifter so as to obtain separation of the rice grains from waste including bran, husk and middling;
• subjecting the rice grains separated in the plansifter to a classification step by means of a grinding machine in order to obtain separation of rice tips from the rice grains of a size equal to or greater than half of a grain of the rice grains;
• subjecting the rice grains exiting the classification step to a second separation treatment by means of a pneumatic cyclone so as to obtain separation between the heavier material falling to the bottom of the cyclone and the lighter material evacuated upwards;
• subjecting the heavier material exiting the second cyclone to a treatment step in a vibrating tank from which the rice bud is precipitated onto a densimeter table so as to obtain a classification of the rice bud according to the specific weight by separating smaller buds from larger ones;
• and
• subjecting the larger buds from the densimeter table to a second vibrating tank.
