Abstract

The procedure and apparatus (1) are used to melt organic product (4) using microwaves. The apparatus (1) consists of at least one microwave waveguide (6) which is fixed to a metal support (3) containing the initial solid organic product (4). The microwaves cause the solid (4) to melt into a layer of liquid on top (11). The apparatus (12) is used to erode the solid product (4), which is in direct contact with the liquid.

Claims (22)

The device (1) under claim 6 has the following characteristics: it consists of a device (13) that causes the movement of the suspended substance (22) upwards to the base (3). 8. The device (1) under claim 7 has the following characteristics: The erosion device (12) consists of a head (13) with teeth (16) and devices (14,15) that drive the head (13) to rotate around the vertical axis xx, and devices that move the head (13) vertically. 9. The device (1) under claim 8 has the following characteristics: the tooth (18) is part of the said blade (17), each blade is oriented vertically on average, the tooth (18) of each blade (17) makes an angle r with the plane (P17) in the vertical direction of the orientation of the corresponding blade (17). 10. The device (1) under claim 9 has the following characteristics: each blade (17) has teeth (18) arranged so that the points (180) are in line with a straight line (L18) that forms an acute angle B open to a line drawn through the said straight line. 11. The device (1) under any of the claims 6 to 10 has the following characteristics: it consists of a device (28,29) which is used to measure the temperature of the upper part of the liquid layer (11). 12. The device (1) according to claim 11 has the following characteristics: the device (28,29) used to measure temperature consists of a metal tube (28) and a temperature measuring rod (29) inserted inside the tube (28). 13. The device (1) under either claim 11 or 12 has the following characteristics: it consists of a device that adjusts the microwave distribution to be a function of the temperature mentioned. 14. The device (1) under claim 13 has the following characteristics: it consists of a device to adjust the erosion control and agitating device (12) according to the function of temperature. 15. The device (1) according to claim 14 has the following characteristics: it consists of a temperature function control device, a sliding device, an erosion and agitation device (12) to move toward the bottom of the support base (3). 16. (4) Melted products obtained by any of the methods under claims 1 to 5. 17. (4) Melted products obtained from equipment (1) under any of claims 6 to 15. 18. A device for the complete melting of solid organic material in a support using microwaves. It consists of a cover for the top opening of the support, at least one waveguide for the passage of microwaves from the source to the solid organic material within the support for melting. The melting proceeds gradually from the top to the bottom of the support. An abrasive device scrapes against the surface of the solid organic material, causing it to detach as suspended particles within the molten material, and also stirs these suspended particles. An upper extension of the abrasive device supports and moves the device downwards, ensuring it continues to scrape the surface of the solid organic material throughout the melting process. 19. The device referred to in claim 18 has a cutting device that includes a toothed, rotating agitator which scrapes against the solid organic material, and the device extending upwards to a driven shaft enclosed within a housing to enable axial and rotational movement. 20. The apparatus referred to in claim 18, which has a conical abrasive surface that excavates solid organic material to cause particles within the suspended material to flow upward. 21. The method for completely melting solid organic material in a microwave support involves several steps to deliver microwaves from a source to the open top surface of the solid organic material in the support. This allows for the gradual melting of the solid organic material from the top down to the core of the support. The solid organic material is then agitated and scraped off by an erosive device, resulting in the suspension of various particles within the molten organic material. The agitation is maintained by continuously and gradually moving the agitation device from the top down to the bottom of the support, and the suspension is agitated by rotating the agitation device. 22. The procedure under claim 21 involves a rotating, toothed, agitating cutting device which is gradually moved from the top to the bottom of the support base (Clause 22, page 5, figure 4).
