Patent attributes
Pre-roll infusing apparatus includes fluid vessel, a fluid pump and an infusion needle for spraying fluid into the pre-roll. An elevator includes a tube nest for receiving a support tube containing the pre-roll and selectively raises the pre-roll to be pierced by the needle. A needle heater is supported for travel along the needle as the elevator moves up and down. The elevator tube nest includes a motor-driven rotatable base for rotating the support tube and pre-roll during infusion. A stepper motor equipped with an encoder controls the raising and lowering of the elevator. The needle may include two or more spaced spray ports. A needle pointer indicates to a user the location of the needle spray ports. The fluid vessel includes a stirrer motor, and the current draw thereof is used to determine the viscosity of the fluid. Different support tubes are provided to accommodate different pre-roll styles.
