Description
Technical field
The present invention relates to suction pipe technical field more particularly to a kind of deformable grain suction pipes, preparation method and application.
Background technique
With the quickening of modern life rhythm, the defect of disposable hard plastic products increasingly shows.Seek it is a kind of safety,
Convenient, healthy, environmentally friendly, inexpensive modern tableware is the eager desire of numerous packaging circle knowledgeable people, in particular with environmental protection
Cry grows to even greater heights, and the research and development and application with true environment protection significance product are to be imminent.
For this purpose, occurring some environmentally friendly suction pipes, including PE laminating adhesive cardboard, paper mould, straw fruit on the market at present
Tableware materials or the products such as the molding of shell class, degradative plastics, biologically degradable starch, but all almost attend to one thing and lose sight of another, it cannot be simultaneously
Meet safety, health, conveniently, environmental protection, low cost the advantages that.
And other kind disposable suction pipes that China's tableware uses at this stage are also not appropriate for being widely applied.For example papery is inhaled
Pipe, first is that environmental pollution is quite big when papermaking, cost is again high；Second is that tellurian area of woods is increasingly reduced, environment is increasingly
Deteriorate.Real environment-friendly products are also not as what other stalk, straw, degradative plastics etc..
It to implement a scientific outlook on development, builds a resource-conserving society and friendly environment society, how to be taken from source
Effective measure supervises enterprise to produce product that is durable, being easily recycled decomposition environmental protection and carrys out substituted for plastic, promotes comprehensive utilization of resources,
It preserves the ecological environment, is pushed further into energy-saving and emission-reduction work, be the emphasis direction for sending out sustainable development path now.
For this reason, it may be necessary to it is a kind of harmless, it is non-toxic and tasteless, degradable and equal in the manufacturing, use and Destruction
Pollution-free, product quality complies fully with state food hygienic requirements, has the characteristics that easily recycling, easily disposition or easily consumption after being finished
Suction pipe.
Summary of the invention
Aiming at the shortcomings in the prior art, the object of the present invention is to provide a kind of harmless, non-toxic and tasteless, easy drops
Solution, and it is pollution-free in the manufacturing, use and Destruction, product quality complies fully with state food hygienic requirements, is finished
Have the characteristics that easily recycling, the easily deformable grain suction pipe of disposition or easily consumption, preparation method and application afterwards.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of deformable grain suction pipe, the raw material including following parts by weight: 40-50 parts of cornstarch, rice starch 40-50
It is part, 10-20 parts of water, 0.2-0.5 parts of sugar, 0.1-0.2 parts of salt, 0.3-0.4 parts of curing agent, 0.4-0.5 parts of waterproofing agent, anti-oxidant
0.5-1 parts of agent.
It further, further include having 30-45 parts of fruit vegetable powder, 0.5-2 parts of edible pigment.
Further, the curing agent is ethylenediamine, diethylenetriamine, diaminomethyl hexamethylene, one in hexahydropyridine
Kind is several.
Further, the waterproofing agent be one of paraffin, gum rosin, stearic acid, organic silica gel or chitosan or
It is several.
Further, the antioxidant is diphenylamines, p-phenylenediamine, dihydro quinoline, (3,5- three-level butyl -4- hydroxy benzenes
Base) thioether, double Lauryl Alcohol esters, bi-myristoleyl, one or more of double octadecanol esters.
Another technical problem to be solved by this invention be a kind of preparation method of deformable grain suction pipe is provided, including with
Lower step:
1) extracting corn starch 40-50 parts, 40-50 parts of rice starch, 0.5-2 parts of edible pigment, sugar 0.2-0.5 parts, salt
0.1-0.2 parts, 0.3-0.4 parts of curing agent, 0.4-0.5 parts of waterproofing agent and 0.5-1 parts of antioxidant are added to single screw extrusion machine
In；
2) by 30-45 parts of fruit vegetable powder, 10-20 parts of water are added into single screw extrusion machine, and stirring squeezes out crushed material；
3) will stirring squeeze out after crushed material be delivered to extruder extrusion, tie rod, cooling, slice obtain suction pipe, wherein squeezing
The temperature of machine barrel is 80-120 DEG C out, and the temperature of die head is 70-100 DEG C, and the temperature of cooling water is 40-50 DEG C.
Further, the draw ratio of the single screw extrusion machine is 20:1, and effective length is 2 meters.
Further, in step 3), obtained suction pipe is subjected to quality inspection after natural drying, removes underproof rice and inhales
Pipe.
Further, in step 3), qualified rice suction pipe is put into ultraviolet sterilizer and is sterilized, sterilizing time 8-
10h。
Another technical problem to be solved by this invention is to provide the above-mentioned deformable grain suction pipe of one kind in beverage application, medicine
Application in product and oral solution.
The manufacturing theory of starch-based edible suction pipe is: progress is mixed in material of main part, various auxiliary agents, water in proportion
Mixed pressure, in extrusion process, material carries out various physics, chemical reaction is that raw material is bonded and generates the related performance of disposable tableware
Internal cause, these reactions are as follows: first at high temperature under high pressure, opening the protein disulfide bond in material of main part, generate molecule sulphur
Acid；After the based polar group of sulfonic acid generates, the compatibility to adherend is just improved, adhesive tension is increased, high pressure and movement rub
It wipes and generates temperature, material is made to obtain boiling and be gelatinized, the input of mechanical energy melts part grain, and water-soluble sex index is aobvious
It writes and improves；With the reduction of starch molecule amount, the permeability of material is also increased；In this way, the viscosity of material, affinity and film forming
Performance is further improved.
The beneficial effects of the present invention are:
1, environment-friendly degradable, 2, the colorful edible band of suction pipe is interesting, and 3, it can be recycled as high-grade feed, 4, it can replace
Make the common demand of people for current suction pipe；It is strong with flexibility, it is added to fruit vegetable powder, moreover it is possible to allow suction pipe to show colourful
A variety of entertaining colors are free of any additive, derive from the Nature, and full of nutrition, available can eat；5, durability is strong,
Can steep hot water two it is more than hour indeformable.
