Abstract: An herb vaporizing apparatus includes an herb receiving port, a grinder to grind the herb, and a heating chamber for heating the ground herb to create a vapor. A first end of the heating chamber is positioned closer to a top of the apparatus than a second end of the heating chamber, such that the ground herb generally moves in at least a partially downward direction as it travels through the heating chamber. The apparatus further includes a screw feeder positioned within the heating chamber that rotates and moves the ground herb within the heating chamber. The apparatus further includes an air pump for pumping vapor out of the heating chamber and a valve positioned along an airway between the heating chamber and a vapor output. The valve permits air and the vapor to move from the heating chamber to the vapor output only while the air pump is activated.
