A vertical packaging machine that includes a hopper with a hopper inlet mouth and at least one hopper outlet mouth, a tube arranged downstream of the hopper with a tube inlet mouth and a tube outlet mouth. A supply conduit is formed by at least the hopper and the tube. Acceleration means is provided and configured for injecting a gaseous fluid into the supply conduit through two injection ports arranged in the supply conduit at different heights with respect to the tube outlet mouth and for causing, with said injection, part of the air present in said supply conduit above the corresponding injection port to follow the injected flow.

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.

An apparatus configured to provide portioned instances of a compressible material includes a channel assembly, a gas source, a cutting assembly, and a discharge assembly. The channel assembly holds a bulk instance of the material extending through upper and lower channels of a continuous channel. The gas source supplies gas to compress the bulk instance. The cutting assembly moves in relation to the channel assembly to isolate the upper and lower channels, severing upper and lower material portions of the bulk instance. The discharge assembly directs gas to impinge on a lower face of the cutting assembly to discharge the lower material portion as a portioned instance. The channel assembly may be moveable, where operation of the gas source, cutting assembly, and/or discharge assembly are based on moving the channel assembly between various positions. The gas supply may be controlled based on a determined property of the portioned instance.

The method includes first configuring a first cross-sectional flow area of a throat within a first air accelerator to discharge a target quantity of a particulate material, the first air accelerator including a body and an adjustable member, an interior surface of the body defining a cavity containing the adjustable member, the throat being at an air outlet of a chamber defined between the body and the adjustable member, the throat being near a discharge end of a singular bore defined by the adjustable member, the first configuring including axially moving the adjustable member along a first longitudinal length of the cavity.

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.

Disclosed is a vertical packaging machine configured for packaging a product. The machine may include a supply conduit formed by at least one hopper through which the product to be packaged is introduced in the supply conduit. A tube is arranged downstream the hopper. The supply conduit includes at least a first passage conduit and a second passage conduit which are separated from one another such that each of the first and passage conduits offers a different path for the product to be packaged. Each of the first and second passage conduits includes a first injection opening and a second injection opening, the first injection openings being located at different heights and in different angular positions in reference to the second injection openings. The machine also includes one or more injection devices and that are configured to inject gas into the first and second gas injection openings.

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.
