A method of infusing wood grilling products with water or other aromatic liquid comprising the steps of:
- (A) providing a plurality of wood grilling products and a first quantity of liquid;
- (B) providing a vacuum infusion chamber containing the first quantity of liquid;
- (C) placing a rack fixture containing the plurality of wood grilling products into the vacuum infusion chamber, and securing the rack fixture, such that all surfaces of the plurality of wood grilling products are exposed to the first quantity of liquid and are submerged within the first quantity of liquid;
- (D) hermetically sealing the vacuum infusion chamber containing the first quantity of liquid and the plurality of wood grilling products;
- (E) evacuating a first quantity of air out of the vacuum infusion chamber in order to extract a maximal quantity of air from tissues, fibers and crevices of an entire cross-section of each of the plurality of wood grilling products while the plurality of wood grilling products are submerged and restrained beneath a top surface of the first quantity of liquid;
- (F) maintaining a vacuum on the plurality of wood grilling products at an optimal negative pressure and for an optimal time duration while the plurality of wood grilling products are submerged and restrained beneath the top surface of the first quantity of liquid;
- (G) obtaining a plurality of infused wood grilling products by introducing a second quantity of air into the vacuum infusion chamber in order to restore the vacuum infusion chamber to an atmospheric pressure so as to infuse a portion of the first quantity of liquid into the tissues, fibers and crevices of the entire cross-section of each of the plurality of wood grilling products while the plurality of wood grilling products are submerged and restrained beneath the top surface of the first quantity of liquid;
- (H) opening the vacuum infusion chamber to facilitate unrestraining and removal of the rack fixture containing the plurality of infused wood grilling products;
- (I) individually transferring each of the plurality of infused wood grilling products from the rack fixture to a corresponding vacuum-sealable pouch among a plurality of vacuum-sealable pouches each containing a second quantity of liquid;
- and
- (J) vacuum-sealing each of the plurality of vacuum-sealable pouches containing a corresponding infused wood grilling product among the plurality of infused wood grilling products and a corresponding second quantity of liquid among the plurality of second quantity of liquids by using a vacuum sealing machine so as to to augment and preserve the infused wood grilling product in an infused state until the infused wood grilling product is to be used.
