The extrusion sheet is pressed by using a sheet extruding machine, the combined raw materials are added into a hopper, the combined raw materials are discharged into a hot water tank from a feed opening under the vibration of an electromagnetic vibrator to form a modified starch sheet, the modified starch sheet is wound around a winding shaft to move forwards under the rotation action of the winding shaft, the formed extrusion sheet reaches a carrier roller through a guide wheel, the extrusion sheet moves forwards under the rotation action of the carrier roller, the extrusion sheet is cut into sheets with specifications through a cutter to form an extrusion sheet, the extrusion sheet is placed on a die cavity, and the extrusion sheet is pressed and formed to form a starch box or a starch disc and a disc.
The combined raw materials can also be directly processed and utilized.
Example 1:
starch bowl:
the structure of the rotary compressor is as follows: the bowl-shaped die 05 is made of stainless steel, a die cavity 06 faces upwards, two sliding rods 07 are arranged at the bottom of the die and penetrate through a cross rod 02, handles 03 are arranged on two sides of the cross rod, a speed reducing motor 01 is arranged on the upper portion of the cross rod, and a die head 04 is arranged on the lower portion of a shaft rod of the speed reducing motor.
The cross rod and the gear motor are lifted through the handle, the combined raw materials are quantitatively put into the die cavity, the gear motor drives the die head to rotate, meanwhile, the cross rod and the die head are pressed downwards through the handle, the combined raw materials are pressed downwards through the die head in a rotating state, a bowl-shaped blank with a set wall thickness is formed, after the set depth is reached, the cross rod and the gear motor are lifted through the handle, and the demolding is performed to form the bowl-shaped blank to be dried.
When the bowl-shaped mold is used for pressing starch bowls, the combined raw material powder is added into a bowl-shaped mold cavity, then the die head is rotated and pressed downwards, so that the combined raw material is attached to the mold cavity of the bowl-shaped mold, the combined raw material is solidified, bonded and formed along with the increase of the temperature, the bowl blank is pushed out of the mold cavity by the demolding mechanism, the bowl blank is placed into a drying box by hands, and the tableware bowl is formed after drying.
Example 2:
starch dish:
making stainless steel material into disc or square disc mold, setting mold cavity in the upper part, pressing the extruded sheet onto the disc mold cavity, heating to solidify the extruded sheet, demolding the disc tableware with an ejector, and stoving to form the starch disc or disc.
Example 3:
starch box:
the box-shaped die is made of stainless steel and is provided with a die cavity, the combined raw material extrusion sheet is placed in the die cavity of the box-shaped die, and the box-shaped starch box is formed after pressurization, heating, solidification and demoulding. The starch box may be square or round.
Example 4:
starch cup:
making a cup-shaped cavity die made of stainless steel, adding the combined raw materials into the cavity die, performing compression molding by rotating an extrusion die, and heating, curing or drying to obtain the cup-shaped starch tableware.
And the die head of the rotary compressor is pressed down while rotating, so that the starch raw materials are combined and pressed for molding.
The performance of the raw materials is as follows:
the glutinous rice expands and loosens after being puffed, and has a pore structure even if being crushed into powder, so that a framework can be formed.
The sticky glutinous rice pulp is made of glutinous rice with amylopectin and heated to make the sticky glutinous rice pulp, and can replace a cementing agent.
The tremella powder is edible fungus, has more dietary fiber, can play a role in strengthening and pulling, is food, and is safe and free of toxic and side effects.
The potato starch is starch made from potatoes, and has a formed structure which is firmer than other starches, so that the potato starch has good rigidity, high strength and good transparency.
The organic silicone oil is a safe water repellent agent, and can resist water and prevent softening when being added into a product.
The technical principle is as follows:
when the starch paste is heated in water, the starch paste forms a transparent state, such as powder leakage in rural areas, vermicelli and wide powder, and is in a semitransparent state after being dried in the air, so that the starch paste has high strength and toughness. According to the invention, potato starch is adopted as a main raw material, glutinous rice pulp is adopted as a binder, puffed glutinous rice flour is adopted as a framework, tremella fibers are adopted as a reinforcing pull-bonding material, organic silicon oil is adopted as a waterproof agent, and the starch is cured under the condition that the compounded composition is heated in a wet state to form an integral structure, which has the effect like powder leakage in rural areas. But the rural leakage powder uses single starch, and compared with the single starch, the combination improves the structure and the performance, thereby achieving the innovative effect.
The method is characterized in that:
the starch tableware is made by adopting puffed glutinous rice flour, potato starch and tremella powder as constitutional raw materials, glutinous rice pulp as a wetting binder and organic silicon oil as a water repellent through mould pressing. The raw materials are all milky white, and the organic silicone oil is colorless, so that the prepared starch tableware has milky or semitransparent appearance, is thorough in appearance, not only is hard in structure and high in strength, but also has an appearance effect suitable for aesthetic impression. The raw materials are food-grade, so the feed is safe to use, and can be reused after being cleaned or used as feed. Therefore, the starch tableware prepared by the method and the raw material combination meets the requirement of environmental protection, and can be biodegraded even when being thrown into a refuse dump as tableware garbage.
Compared with the background document, the potato starch is directly used as the main raw material, and the starch is not fermented, so that the potato starch does not contain acid and does not need to be neutralized by adding alkali; titanium dioxide minerals are not added, so that the paint is safe, easy to degrade and free of residues; glycerin is not used, so that the product cannot soften and absorb moisture; gelatin is not used, and glutinous rice pulp is used as a binder, so that the glutinous rice flour is not easy to deteriorate under a dry condition and cannot absorb water for softening; instead of using plant fiber powder, tremella is used as the fiber material.
In summary, compared with the technical content of the background art, the invention has the advantages that the raw material combination is different, the processing method is different, and therefore, the obvious progress and the substantial effect are generated, and the invention is creative.
