Systems and methods for measuring tobacco for packaging in pouches are disclosed. A system includes a hopper structured and arranged to hold a granular material in a hopper cavity. The system also includes a measuring system including a measuring cavity and a tube that is slidable in the hopper cavity between a first position unaligned with the measuring cavity and a second position over and aligned with the measuring cavity. The measuring system is configured to continuously communicate a vacuum to the measuring cavity. The measuring system is configured to move a portion of the granular material from the hopper cavity to the measuring cavity when the tube is in the first position. The measuring system is configured to move the portion of the granular material from the measuring cavity to a pouch making machine using pressurized gas that overcomes the vacuum when the tube is in the second position.

A clamping and conveying device for a material bag filling system is provided. Through displacement of X-axis rails and a Z-axis rail and rotation of rotating arms, grippers can be rotated and inserted into a filling tube portion of a material bag. Cantilevers can be moved away from each other for the filling tube portion to be stretched. Through the rotation and return of the rotating arms, the displacement of the cantilevers and the clamping action of the grippers, the filling tube portion is clamped stably. The cantilevers are displaced to the bottom of the material filling device by the Z-axis rail and the X-axis rails. The filling tube of the material filling device is displaced to enter the material bag for blowing air and filling the material. Through a conveyor belt, the material bag with the filled material is conveyed to a sealing device for sealing.

An air accelerator dosing tube for a form/fill/seal machine used to package fine cut tobacco material includes an axially-adjustable annular venturi communicating with the particulate material passage. A lining of polyether ether ketone optionally covers surfaces exposed to the particulate material. A metering assembly for delivering predetermined quantities of particulate material at predetermined time intervals may also be fabricated from polyether ether ketone. Each dosing tube is adapted for calibration by adjustment of the annular venturi to produce a predetermined force at a predetermined stand-off distance. In operation, consistent simultaneous operation of multiple dosing tubes, each of which has been calibrated, gives substantially uniform deposit of particulate material in pouch-type packages. The particulate material may include finely cut tobacco in addition to humectants, flavorants, and other tacky substances.

The present invention relates to a method and device for collecting, washing and drying solid particle samples used in collecting the solid particle samples in sample collection work in the fields of industrial production and scientific research, and particularly relates to a method and device for collecting, washing and drying solid particles by pneumatic conveying. A method for collecting, washing and drying solid particles by pneumatic conveying comprises: collecting and conveying a sample mixture containing solid particles into a solid particle collecting and processing device by a pneumatic conveying airflow; then disturbing and diluting the collected sample mixture containing solid particles in the solid particle collecting and processing device by the pneumatic conveying airflow and a washing liquid to filter and wash solid particle samples. The present invention overcomes the problems in the prior art: washing and drying to realize automatic one-stop completion of collection.

A table top appliance rapidly fills a pouch through some mechanical actuation or automation by inserting the pouch into the appliance and the machine fills the pouch. One embodiment of the food pouch filling station may be a mechanical version that includes a method to pump or push the contents of the container into the pouch. A second embodiment of the food pouch filling station may be an electric pump version that fills pouches and may have the option of controlling the amount of food dispensed. The food pouch filling station may also include a valve that connects to the pouch to control the flow to the pouch.

A pellet column is formed in a metering duct. The lowermost pellet is located in a connection point where an outlet duct is connected to the metering duct and leads transversely away therefrom. A first duct, which opens into the metering duct via a first duct mouth above the connection point, is impinged with negative pressure, wherein a pellet is suctioned onto the first duct mouth and is fixed thereto. This pellet acts as a block for the pellets thereabove. A second duct, which opens into the connection point via a second duct mouth, is impinged with positive pressure, wherein the pellet at the connection point is pneumatically ejected via the outlet duct and supplied to a container. After the ejection of the lowermost pellet, the negative pressure in the first duct is switched off such that the pellet held at the first duct mouth advances toward the connection point.
