Abstract

A radiofrequency heating system and methods for processing agricultural products are provided herein. The method may include positioning an agricultural product between two electrode assemblies of a radiofrequency (RF) circuit, closing the RF circuit, and heating the agricultural product to a threshold temperature in greater than a threshold amount of time.

Claims (32)

1. A method, comprising:

positioning an enclosure containing an agricultural plant product between two electrode assemblies of a radiofrequency (RF) circuit, wherein the agricultural plant product is cannabis;

closing the RF circuit;

subjecting the cannabis to RF waves via the closed RF circuit for at least four minutes; and

heating and drying the cannabis via the RF waves, the cannabis heated to a final temperature ranging from 75 degrees Celsius to 115 degrees Celsius via the RF waves.

2. The method of claim 1 , wherein the enclosure is a moving enclosure, and wherein medicinal properties of the cannabis are maintained following the heating and the drying of the cannabis.

3. The method of claim 1 , further comprising differentiating that the cannabis has reached a threshold temperature, and then automatically opening the RF circuit via a controller.

4. The method of claim 3 , where a temperature of the cannabis is monitored via at least one temperature probe positioned within the enclosure that provides an output to the controller.

5. The method of claim 1 , wherein a frequency of the RF waves is 27.12 MHz±0.163.

6. The method of claim 1 , wherein the enclosure comprises vents.

7. The method of claim 1 , wherein the enclosure is a tray comprising polycarbonate, the polycarbonate tray including a fitted lid.

8. The method of claim 7 , wherein a bottom of the polycarbonate tray comprises a mesh.

9. The method of claim 1 , wherein the cannabis is dried via vaporization of water within the cannabis , and wherein the cannabis is dried without adding any moisture to the cannabis from a foreign source.

10. The method of claim 1 , further comprising heating the cannabis with a heating rate that is less than 19.0 degrees Celsius per minute via the RF waves.

11. A method of treating an agricultural product, comprising:

subjecting the agricultural product to radiofrequency (RF) waves, wherein the agricultural product is cannabis;

heating the cannabis to a final temperature ranging from 75 degrees Celsius to 115 degrees Celsius via the RF waves at a heating rate that is less than 19.0 degrees Celsius per minute; and

via subjecting the cannabis to the RF waves, reducing a microbial load of the cannabis to an acceptable limit while avoiding degradation of a chemical composition of the cannabis.

12. The method of claim 11 , wherein the chemical composition of the cannabis includes THC.

13. The method of claim 11 , wherein the chemical composition of the cannabis includes color chemicals and terpenes.

14. The method of claim 11 , wherein the cannabis is subjected to the RF waves for at least four minutes, and wherein the heating rate is greater than 6.5 degrees Celsius per minute.

15. The method of claim 11 , further comprising drying the cannabis via the RF waves.

16. A method, comprising:

loading a leafy agricultural plant product into an enclosure;

positioning the enclosure containing the leafy agricultural plant product between two electrode assemblies of a radiofrequency (RF) circuit;

closing the RF circuit;

subjecting the leafy agricultural plant product to RF waves via the closed RF circuit; and

heating the leafy agricultural plant product via the RF waves to a final temperature ranging from 75 degrees Celsius to 115 degrees Celsius, the leafy agricultural plant product heated at a heating rate that is less than 19.0 degrees Celsius per minute.

17. The method of claim 16 , wherein the leafy agricultural plant product is cannabis.

18. The method of claim 16 , wherein a frequency of the RF waves is 27.12 MHz±0.163 MHz.

19. The method of claim 16 , wherein the heating rate is greater than 6.5 degrees Celsius per minute, and wherein the enclosure is made of polycarbonate.

20. The method of claim 19 , further comprising drying the cannabis contained within the enclosure via the RF waves.
