An apparatus for processing a material, the apparatus comprising - a feeder configured to receive the material; - a press module operatively coupled to the feeder, wherein the press module comprises a body - having a volume of space for receiving the material from the feeder, wherein the feeder comprises a first piston configured to move the received material into the volume of space of the body, - having a first end and a second end opposite to the first end, and - comprising a pressing means configured to press and move the material received in the volume of space towards the first end of the body; - a sieve (106, 300) having a first side and a second side opposite to the first side, wherein the sieve is arranged at the first end of the body, and wherein the second side of the sieve faces the first end of the body, and wherein the sieve is configured to receive the material in a pressed form from the first end of the body via the second side of the sieve and to eject the material in a processed form via the first side of the sieve, characterized in that the sieve comprises a set of apertures (302, 306), and wherein the set of apertures extend from the first side of the sieve to the second side of the sieve, and that a diameter of each aperture of the set of apertures is larger at the first side as compared to the second side of the sieve, such that the material passes through the set of apertures (302, 306) and heats up because of friction experienced by the material while passing through the set of apertures (302, 306), due to high pressure and small volume set of apertures (302, 306), wherein the diameter of each aperture of the set of apertures (302, 306) at the first side and the second side is diligently selected to ensure that the material experiences friction while passing through the sieve (106, 300); and - cleaning means arranged to clean the second side of the sieve. - a feeder configured to receive the material; - a press module operatively coupled to the feeder, wherein the press module comprises a body - having a volume of space for receiving the material from the feeder, wherein the feeder comprises a first piston configured to move the received material into the volume of space of the body, - having a first end and a second end opposite to the first end, and - comprising a pressing means configured to press and move the material received in the volume of space towards the first end of the body; - having a volume of space for receiving the material from the feeder, wherein the feeder comprises a first piston configured to move the received material into the volume of space of the body, - having a first end and a second end opposite to the first end, and - comprising a pressing means configured to press and move the material received in the volume of space towards the first end of the body; - a sieve (106, 300) having a first side and a second side opposite to the first side, wherein the sieve is arranged at the first end of the body, and wherein the second side of the sieve faces the first end of the body, and wherein the sieve is configured to receive the material in a pressed form from the first end of the body via the second side of the sieve and to eject the material in a processed form via the first side of the sieve, characterized in that the sieve comprises a set of apertures (302, 306), and wherein the set of apertures extend from the first side of the sieve to the second side of the sieve, and that a diameter of each aperture of the set of apertures is larger at the first side as compared to the second side of the sieve, such that the material passes through the set of apertures (302, 306) and heats up because of friction experienced by the material while passing through the set of apertures (302, 306), due to high pressure and small volume set of apertures (302, 306), wherein the diameter of each aperture of the set of apertures (302, 306) at the first side and the second side is diligently selected to ensure that the material experiences friction while passing through the sieve (106, 300); and - cleaning means arranged to clean the second side of the sieve.
