  • Patent number: 9555965
    Abstract: Method for feeding material into a rotary shaper device in a pneumatic pipe transport system for material, in which the material is conducted along a feeder channel to the rotary shaper device, in which case the material to be handled is conducted into the shaper device and/or through it by the aid of at least partly the suction and/or a pressure difference of the pneumatic pipe transport system. In the method the material is acted upon in the feeder channel, or in the channel leading into it, with at least one guide member, which is configured to reduce the undesirable rotation of the material in the feeder channel and/or to improve the access of replacement air into the rotary shaper. The invention also relates to an apparatus.

  • Patent number: 9440807
    Abstract: A hopper apparatus (100) provides a conveyance passage (150) equipped with a nitrogen purge system. In operation, the hopper apparatus (100) is installed over an opening of a process vessel (200). Chemical matter may be conveyed through the conveyance passage (150) to land within the process vessel (200). The hopper apparatus may have a flap valve (141) that serves to isolate the interior space of a process vessel (200) from the ambient environment outside the process vessel (200). The hopper apparatus (100) may also inject nitrogen at various rates into the falling stream of chemical matter as it is conveyed into a process vessel (200). The hopper apparatus (100) may also provide a ventilation sleeve (180) providing ventilation and extraction of dust and vapors emitted from the falling stream of chemical matter.

  • Patent number: 9399201
    Abstract: An exemplary homogenizer includes a valve plate stack having a shim sandwiched by a pair of valve plates, the stack being concentrically aligned by a center stud. Each of the valve plates includes a middle annulus radially situated between an outer rim and an inner raised hub. Each middle annulus includes annulus apertures that help increase flow rate. When the homogenizer is in a working position, the valve plate stack is compressed, and fluid entering through an inlet is homogenized as it passes through a gap between outer rims of adjacent valve plates. The minimum gap between the valve plates is set by the thickness of the shim. In a cleaned-in-process cleaning position, pressure is relieved from the stack, and a spring between adjacent valve plates separates adjacent valve plates. Enhanced drainage, and springs that are substantially sealed from fluids by spring retainers and O-rings, help promote sanitation.

  • Patent number: 8535402
    Abstract: A particle reduction system and method is disclosed having an air stream accelerator, a feeder assembly, a variable speed wheel lock operably associated with the feeder assembly for releasing raw material into a conveying air stream created by the positive displacement pump, and a particle conditioning assembly. The raw material is carried by the conveying air stream through the particle conditioning assembly, where particle of the material are collided with each other for the purpose of reducing the size of the particles. In some embodiments, a non-thermal drying system can be used to extract moisture from the raw material. The moisture/solids separation occurs, in large part, due to a head-on collision of two conveying air streams. The collision creates a large squeezing force, much higher than a centrifuge or filter. This impact squeezing acts to squeeze the moisture out of the raw material.

    Abstract: A new method and concept for the recovery of valuable materials from solid waste and the conversion of organic solid waste and sewage into crude oil, gas, usable elemental solids and water uses a two step process, solid waste reduction and an organic fusion process. Two resources are used in the Waste Resource Process, solid waste (municipal garbage) and waste water (municipal sewage). Waste water goes directly into the Organic Fusion Process. Solid waste requires processing for removal of non-organic products and preparation of the organics that are used in the Organic Fusion Process. Solid waste organics used in the Organic Fusion Process include, plastics, papers, food and yard waste, organic construction debris, waste oils, many household and commercial chemicals; anything with a hydrocarbon molecular structure.
