  • Patent number: 8226401
    Abstract: Gum manufacturing machinery and method of manufacturing gum is illustrated in which a gum loafing machine generates loaves of finished gum that are then subsequently run through a gum conditioner to more uniformly set the temperature and viscosity of the gum material prior to further processing. Upon achieving the appropriate conditioning level, a further forming extruder may be used to generate a continuous gum ribbon for subsequent rolling and scoring operations. The gum conditioner may include vertically stacked conveyors that have different operational modes including a first mode that provides a serpentine path for a long residence time and a second mode that provides a cascading path that avoids or bypasses much of the length of some of the conveyors to provide a shorter residence time. The gum manufacturing machinery may be used in an adjustable manner so as to accommodate difference gum recipes for different batches of gum product.

  • Publication number: 20120126446
    Abstract: The invention relates to a method for producing a concrete body having a planar upper side, wherein a high surface quality is obtained. In the method, a concrete body is extruded from unset concrete and is provided with a groove profile at the upper side thereof by means of a profiling unit. By means of the profiling unit and depending on the comb-shaped profile thereof, the sand particles are separated according to size, wherein large sand particles are displaced from the surface area of the concrete body toward the inside, this being toward the interior of the concrete body. Only fine sand particles can pass the profile, whereby raised areas of the groove profile are formed, which are made of extremely fine-grained unset concrete. Subsequently, the upper side of the concrete body is leveled by means of a leveling unit, wherein the raised areas of the groove profile are crushed and the fine-grained unset concrete of the raised areas of the groove profile is distributed to form a cover layer.

  • Patent number: 8157556
    Abstract: A system for controlling the dimensions of an extrudate exiting an extruder and for compensating for the variations in the extrusion rate of the extruder, expansion rate and rate of travel of the extrudate through sizing devices by changing the speed of an extrudate puller device, includes an extruder which extrudes the extrudate; a conveyor system comprising rollers and a series of sizing devices; a puller device for pulling the extrudate through the sizing devices; and a laser proximity measuring device to assist the system in keeping the desired shape of the extrudate. The laser proximity measuring device includes at least one pair of optical non-contact displacement transducers, a real time processor, and an interactive touch screen display unit. The transducers emit a laser beam which provides a laser point on the side of the extrudate.

    Abstract: An extrusion and conditioning apparatus, with an extruder in a conveying position, leads into a conveyor housing connected in a sealed manner to a pneumatic supply line and to a pneumatic conveyor line in which extruded material can be removed pneumatically, by means of superheated steam, via the conveyor line. The extruder can be moved from the conveying position into a bypass position, in which the extruder leads to the exterior of the conveyor housing, having a means for sealing the supply and conveyor lines and the conveyor housing from the surroundings when the extruder is in the conveying and bypass positions.

  • Patent number: RE42424
    Abstract: In the extrusion of feed-stuff pellets and relevant consumer products, the extruded products are subject to expansion as a result of the boiling of their water content when the products, after being exposed to high extrusion pressure and a correspondingly high temperature, are discharged to the atmosphere through the extrusion nozzles. Such an expansion is directly aimed at, but it is desirable to be able to control it, which is difficult by adjustment of the ordinary process parameters. With the invention it has been found that the expansion which arises can be controlled in a highly constant manner, i.e. by carrying out the extrusion into a closed chamber in which an over-pressure of a few bar is established in relation to the atmospheric pressure, and which can be regulated. The extrusion products can be continuously discharged from this chamber, or they can be discharged intermittently in portions.
