Description

Degradable straw for sucking liquid food

Technical Field

The utility model belongs to the technical field of food, and particularly relates to a degradable straw for sucking liquid food.

Background

The traditional plastic suction pipe is generally made of polypropylene plastic, and the polypropylene plastic has good chemical stability and is difficult to degrade in natural environment. Because the consumption of the plastic suction pipe is astonishing, and the plastic suction pipe is small and light and is difficult to recycle, most of the plastic suction pipe is treated as dry garbage, and a lot of plastic suction pipe flows into the sea and becomes tiny plastic fragments under the irradiation of the sun, and the tiny plastic is harmful to the health of marine organisms and human beings. For environmental protection, China in 2020 restricts the use of disposable non-degradable plastic straws. At present, the widely used paper straws which replace disposable non-degradable plastic straws have poor smoking experience and poor taste, and chemical additives such as bleaching agents, adhesives and the like used in papermaking pollute the environment. Therefore, a new straw which can satisfy the function of sucking liquid food by the straw and is healthy and environment-friendly is needed.

SUMMERY OF THE UTILITY MODEL

In order to replace the existing disposable non-degradable plastic straw, reduce the raw material cost of the straw and reduce the pollution of the discarded straw to the environment, the utility model provides the degradable straw for sucking liquid food.

The utility model adopts the following technical scheme:

the straw is a sweet potato starch straw, the external equivalent pipe diameter of the straw is 6-15 mm, and the wall thickness is 1-2 mm.

A closed reinforcing layer is arranged at the opening at one end or at the openings at the two ends close to the straw.

The thickness of the reinforcing layer is at least larger than 1mm, and the axial width of the reinforcing layer is larger than 2 mm.

The cross section of the straw is of a circular or polygonal structure.

The surface of the straw is provided with an enhanced texture structure.

The reinforced texture structure is a strip-shaped texture arranged along the axial direction of the straw or a spiral texture arranged along the circumferential direction of the straw.

The whole straw is bent or linear.

The straw is a cured sweet potato starch straw or an uncured dried sweet potato starch straw.

The technical scheme of the utility model has the following advantages:

A. the straw structure made of the sweet potato starch as the main raw material can be directly used for sucking beverages, the problem of edible safety does not exist, the straw made of the sweet potato starch can be naturally degraded, and after the straw is used, the straw is only required to be thrown into kitchen garbage and treated according to wet garbage, so that the environment is not polluted; the sweet potato is used as a main crop in China, is suitable for planting in south and north, is high in yield and low in price, is a healthy raw material, is made into a straw by using sweet potato starch, is low in raw material cost, is simple in manufacturing method, and is easy to realize industrial popularization.

B. According to the utility model, the enhanced texture structure is arranged on the surface of the degradable straw, so that the overall strength of the straw is enhanced, and meanwhile, through different liquid soaking experiments, the straw slightly expands after being soaked for 1-48h, but can still keep better hardness and shape, and has better anti-soaking performance.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figures 1 and 2, the utility model provides a degradable straw for sucking liquid food, which is a sweet potato starch straw, the external equivalent pipe diameter of the straw is 6-15 mm, and the wall thickness is 1-2 mm. The main material of the straw is sweet potato starch, the straw structure with different diameters and wall thicknesses can be manufactured, the outer wall size includes but is not limited to 6mm, 8mm, 9mm, 10mm and 12mm, and the wall thickness size includes but is not limited to 1mm, 1.5mm and 2 mm.

In order to avoid the cracking of the opening of the straw, as shown in fig. 2, a closed circular arc-shaped reinforcing layer 2 is arranged at the opening at one end or at two ends close to the straw, the reinforcing layer is also made of sweet potato starch, the thickness of the reinforcing layer 2 is at least larger than 1mm, and the axial width of the reinforcing layer is larger than 2 mm.

In order to enhance the stiffness and the anti-soaking properties of the straw, a reinforced texture 1 is provided on the surface of the straw, as shown in figures 2 and 3. FIG. 2 shows the enhanced texture as a strip of texture disposed axially along the straw, and FIG. 3 shows the cross-section as a lace; FIG. 4 is a helical texture disposed circumferentially along the straw. The overall structure of the straw is curved or linear, and different curved radians can be manufactured according to the use scene. Of course, the interestingness of the surface of the straw can be increased, and the straw made of the sweet potato starch can be decorated. The cross section of the straw can also be in a circular or polygonal structure, such as a triangle, a pentagon, a hexagon and the like.

The straw provided by the utility model is produced by adopting an extrusion method, production equipment comprises but is not limited to a manual extruder, a single-screw extruder and a double-screw extruder, and sweet potato raw materials are prepared for direct processing treatment.
