  • Patent number: 7556047
    Abstract: A method of expanding tobacco involves introducing a steam flow and a tobacco material into a duct having an inlet and an outlet and defining an arcuate flow path. The tobacco is entrained in the steam flow and conveyed along the arcuate flow path and toward the outlet. The presence of the steam results in volumetric expansion of the tobacco as the steam and entrained tobacco travel along the flow path. The steam and entrained tobacco are then collected and separated. As such, an expanded tobacco is provided.

A pivoted retainer (22) is pivotally connected to the frame and movable between a non-retaining position and a retaining position for retaining and supporting the last slide of the block. The retainer is actuated by a pneumatic rotary actuator. The pusher moves toward its rearmost position as soon as the last slice is in a retained and supported situation.

  • Patent number: 4945930
    Abstract: Apparatus for the expansion of tobacco includes a substantially cylindrical container (10), conveyors for feeding tobacco into the container and jet nozzles or slits for introducing a heating medium in the form of steam and/or humid air into the container. The jet nozzles or slits (12) are arranged substantially longitudinally of the container axis serving to direct high pressure steam and/or humid air substantially tangentially to the interior surface of the container (10) to engage the tobacco being fed into the container causing a turbulent mixture of steam, and/or humid air, and tobacco to travel along a helical path and to be maintained by centrifugal force in close proximity to the interior surface of the container as the stream moves axially therein and to maintain the circulation and to provide a succession of repeated high relative velocity, highly turbulent and dispersive contacts between the heating medium and the tobacco.

  • Patent number: 4922932
    Abstract: A tobacco feeder assembly utilizes a column of tobacco and a rotary conveyor to feed tobacco particles to a treatment zone which is maintained at above atmospheric pressure. The column of tobacco is maintained in the feed tube by control of the rotational speed of the rotary conveyor and provides an effective vapor barrier which prevents egress of the impregnating or treatment medium into the atmosphere.

  • Patent number: 4790335
    Abstract: A method and apparatus for curing tobacco is provided wherein each leaf is conveyed through a dual chamber curer. The stem of the tobacco leaf is disposed within the upper chamber while the leaf is disposed within the lower chamber. A pre-determined temperature difference is maintained between upper and lower chambers so that the stem and leaf are cured in approximately the same time period thereby preventing overcuring of the leaf.

  • Patent number: 4733676
    Abstract: Apparatus for slicing tobacco bales for conditioning in which the bales are moved from a conveyor (2) onto an adjacent lift device (16) by a first pusher (6), and are then sliced by a slicing blade (20) which is moved horizontally into engagement with the top of the bale and slices the bale while the lift device is dropped slightly to assist in cleaving the bale. The lift is then actuated to raise the bale ready for the next slicing operation, after the previous slice has been ejected by a second pusher (22).

  • Patent number: 4730627
    Abstract: An improved method and apparatus for treating particulate material with a liquid additive in a rotatable cylinder involves the use of a pressurized fluid such as steam directed obliquely against the inner wall of the cylinder to effect a cleaning action on the inner wall as the cylinder is rotated and to augment agitation action produced by the rotational movement of the cylinder and gravitational forces acting on the particulate material. Strategically located spray nozzles apply controlled amounts of liquid additive to the particulate material as it is undergoing agitation by the combined effects of the applied forces. The method and apparatus disclosed are particularly suited to the treatment of tobacco with casing materials.

  • Patent number: 4664131
    Abstract: An arrangement for transporting, storing, and blending tobacco employs a plurality of ventilated containers, each containing bales of a designated grade of tobacco. Containers are stored side-by-side and stacked several containers high, and rows of stacked containers are placed back-to-back so that all of the doors face outwardly. Following storage, the containers with various grades of tobacco are moved to a blending conveyor belt, and bales from the various containers are combined on the belt to form moxules of tobacco of a desired blend.

  • Patent number: 4640299
    Abstract: An apparatus for drying and conditioning tobacco leaves, including a heater for heating conditioning air for conditioning tobacco leaves after drying, a temperature controller for controlling the heater so that the temperature of the conditioning air becomes a preset temperature, an atomized water sprayer for cooling the conditioning air fed to the heater, a humidifier for humidifying the conditioning air, and a humidity controller for detecting the moisture content of the tobacco leaves after drying and conditioning and controlling the humidifier so that the moisture content of the tobacco leaves becomes a target moisture content. The humidity controller is so constructed as to control the humidifier on the basis of a wet-bulb temperature. Saving of heat energy can be attained, and because a cooling chamber is not needed, the apparatus can be made compact and it becomes easier to stabilize a target moisture content.
