  • Patent number: 11472589
    Abstract: A pouch conditioner having a roller frame positioned over a bottom conditioning belt is disclosed. The roller frame includes a housing that has a pair of opposed guide plates, between which are positioned a plurality of conditioning rollers, a top conditioning belt, and a top conditioning belt drive. The top conditioning belt is disposed about the conditioning rollers. Each of the conditioning rollers is coupled to the guide plates by a pair of actuators that provide each roller with independent articulation and individual compressive force. The distance between the bottom conditioning belt and the top conditioning belt defines a conditioning gap through which product containers are advanced. The height of the conditioning rollers relative to the bottom conditioning belt may be varied to provide a graduated conditioning gap.

  • Patent number: 11162218
    Abstract: The multi-stage modular horizontal digester is primarily comprised of a single auger in a horizontal orientation. The single auger includes sections of lesser and greater inner diameter, thus creating sections of that allow for mixing and time to operate on the contents, and sections where the liquids are squeezed out. As compared to the known processing methodology, the multi-stage modular horizontal digester creates numerous benefits. For example, by maintaining elevation of the pulp, it can be directly expelled into the hydrapulper without the need for an additional pump. Processes can be changed quickly by altering the rotation speed, auger sections, or chemical inputs and outputs without the need to move heavy tanks or adjust pumps. In other words, there is no need for the standard cascade-style system where the pulp descends through a step, is raised to the next step, and so forth.

    Abstract: In a parallelepiped agricultural baler flake transfer events are sensed e.g. by the activation of a pre-compression chamber switch or other means indicating that the pre-compression chamber is full and a signal is sent to the baler control logic. The baler logic records in memory the GPS location of the baler at the time of the flake transfer event. A map is then generated showing the GPS location of each flake transfer event. The average crop quantity per flake is determined e.g. by weighing a finished bale and dividing the bale weight by the number of flakes per bale and programming the information into the baler logic. Finally the crop yield for a given field area is determined in the baler logic by multiplying the average crop quantity per flake by the number of flake events recorded in the given area.

In the method a dried wood block (1) is compressed at least in one direction and the compressed wood block (1 kept in compressed shape, for instance between walls (6); (7), and shifted into a heating chamber, which to its cross-section is a closed chamber of predetermined shape and free from oxygen, whereby still in the said chamber the temperature of timber block (11) is quickly raised to 210–390° C. and the timber block kept tight under controlled compression in each direction and that the timber block (11), still under compression, is quickly and controllably cooled, for instance placing it in a space between cooling walls (8).

  • Patent number: 7104191
    Abstract: A method is provided for determining the throughput of a parallelepiped agricultural baler. The baler has a feed duct communicating between a crop pick-up assembly and a baling chamber and the feed duct serves as a pre-compression chamber to accumulate crop to a predetermined density before the crop is transferred to the baling chamber. The transfer of the crop from the feed duct (pre-compression chamber) to the baling chamber is accomplished by a stuffer mechanism actuated in response to a crop density sensor associated with the feed duct (pre-compression chamber). The baler further has a plunger mechanism that compresses the crop into a column to form a bale in the baling chamber. The invention senses when the crop in the feed duct (pre-compression chamber) has reached a predetermined density for transfer to the baling chamber and when the plunger has attained a home position that allows for transfer of crop from the feed duct (pre-compression chamber) into the baling chamber.

  • Patent number: 7028610
    Abstract: A machining waste metal recycling machine has an in-feed hopper. The hopper uses paired augers to move the waste metal through the hopper to a cutting and transporting auger. The hopper augers are powered independently from each other, and may be individually reversed or reversed as a group to clear jams. In the event a jam is not cleared through one or more reversal cycles, the remaining augers may be operated to clear the hopper, thereby avoiding the need for manual unloading. Within the hopper are one or more shear bars that are provided to sever bunches or bundles of machining waste and thereby clear tangles which might otherwise jam the augers. The cutting and transporting augers ultimately feed a reciprocating compactor having a movable gate with one or more grooves for controlled drainage of machining oil and other liquid, as the machining waste metal is compressed into pellets.

  • Patent number: 7011018
    Abstract: The material compactor generally includes a feed apparatus and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having confronting compression plates and an adjustably taperable portion. The area of the inner cavity of the final compaction chamber can be adjusted to become measurably smaller (tapered) or larger at the opened discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the chamber significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus and out an open discharge port.

  • Patent number: 6948424
    Abstract: The material compactor in accordance with the present invention generally includes a feed apparatus, a preliminary compaction apparatus, and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having an adjustably taperable choke tube. The area of the inner cavity of the final compaction chamber can be tapered to become measurably smaller or larger at the discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the tapered choke tube significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus.
