Biodegradable plant fiber raw material grains composition
A recently filed patent (Publication Number: US20230145833A1) describes a composition of biodegradable plant fiber raw material grains. The composition includes plant fiber powder, starch, vegetable gum powder obtained by fermenting starch, water-soluble polymer glue, and water-soluble cellulose derivative. The plant fiber powder is obtained from natural plant materials such as stem, bark, leaves, or pericarp, which are pulverized and dried to create a powder with a water content of 20% or less. The starch used in the composition can be derived from various plants including wheat, potato, corn, sweet potato, cassava, lotus root, rice, or algae. Additionally, the composition may also include bamboo vinegar solution.
The patent also outlines a method for producing these biodegradable plant fiber raw material grains. The method involves several steps, including acquiring the raw materials and adjusting their ratios based on the desired processed product and molding method. The fiber powder is kneaded in a first kneader to soften it, while the starch and water-soluble cellulose derivative are kneaded in a second kneader to activate fluidity of powder granules. The vegetable gum powder is kneaded separately to make it viscous. These ingredients are then combined in a fourth kneader along with the water-soluble polymer glue and agitated to uniformly knead the mixed raw material. The mixed raw material is then extrusion-molded into string-shaped strands using a molding device and subsequently cut into granular raw material grains. The grains are cooled and packaged for use.
The molding device used in the method includes a transport unit with power screws and transport rods separated in multiple stages. Blades are provided on the outer periphery of each transport rod, with the size of the blades varying along the transport unit. The temperature of each transport rod is controlled, and exhaust pipes are connected to a vacuum machine to discharge water and water vapor during the agitation and transportation process. The raw material outlet of the molding device is equipped with a molding extrusion platen with opening holes through which the mixed raw material is extruded and molded into strands.
The method also includes a cooling system for the strands, which involves a transport stage, a power device, and fans to blow air and cool the strands. The cutting unit, located outside the power device, cuts the strands into raw material grains using a rotating cutter blade. The second cooling system includes a series of tubs and blowers to collect, cool, and transport the raw material grains to a storage tub.
Overall, this patent describes a composition and method for producing biodegradable plant fiber raw material grains, offering potential applications in various industries that require environmentally friendly and sustainable materials.
