Abstract

The invention relates to environmentally-friendly tableware, in particular to fully naturally-degraded and recycled biological rice (first-level aged grain) starch tableware and a manufacturing process thereof. The manufacturing process is characterized by comprising the following steps of: uniformly mixing and stirring biological rice starch comprising 55 to 60 weight parts of rice meal and 35 to 40 weight parts of biological edible auxiliary mixed material which consists of 30 percent of rice starch adhesive, 8 percent of edible cassava and 2 percent of degradation agent in a mixing unit, performing modified dissolution at the temperature of between 60 and 80 DEG C, devolatilizing, and extruding granules into sheets with the width of 100 to 300mm and the thickness of 1.5 to 3 mm at constant temperature of between 160 and 180 DEG C in a TSK-65/44 parallel co-rotating double screw extruder; performing automatic hot-forming on the sheets in a tableware mold in various dimensions and shapes at the temperature of between 50 and 60 DEG C, disinfecting through an ultraviolet disinfection machine, cutting edges and shearing through a shearing machine, cooling and molding; and finally, detecting according to national standards by a quality inspector to meet the national standards of GB18006.1-1999 and GB18006.2-1999, packaging and warehousing. The tableware can be naturally degraded, is degraded within one month in a completely exposed environment, is degraded within 72 hours in water, is not degraded within six months under the condition of a sealed package, and is convenient to preserve.

Description

Rice one-level grain in storage for years starch dishware and manufacture craft thereof

One, technical field

The present invention relates to a kind of environment protecting tableware, the biological Starch rice tableware and the manufacture craft thereof of particularly a kind of full natural degradation and recycling.

Two, background technology

Traditional disposable tableware mostly is to utilize expanded plastic to make, because they can not natural degradation, forms " white pollution " and becomes current one big public hazards.Also once released degradable papery, moulded pulp set for dining on the market.But mould tableware because of have drawn from bamboo wood forest raw material and cost are higher than bubble, the not only wood protection of unfavorable country and price competitiveness are so fail extensively to promote.Though some places are carried out doing starting material with branch, grass roots, straw and produced tableware, gown film and recombining process have not only increased manufacture difficulty and cost, and do not reach the purpose of environment-friendly degradable, so can not mass production.

Three, summary of the invention

It is short that the technical problem to be solved in the present invention provides a kind of natural degradation cycle, and manufacture craft is easy, not only 100% can natural degradation in 72 hours, and can make animal-feed or agricultural fertilizers such as pig, duck, chicken after real the recovery.

For solving the problems of the technologies described above, technical scheme of the present invention is:

Full natural degradation biological rice (grain in storage for years) starch dishware, it is characterized in that it is after adding edible Tapioca Starch mixing by biological Starch rice, through 60-80 ℃ of temperature modification dissolving, under 160-180 ℃ high temperature, make sheet material and hot pressing moulding tableware again after making granulating, but as long as order articles for use packing box wrapped products such as the mess-tin of just production various size of mold exchange shape, supermarket pallet, bean curd box, bowl, bowl lid, ice cream cup, can body, preserved fruit box, pickles box, bonbon box, cake box, fruit packing box, egg holder more.

Four, rice (grain in storage for years) starch dishware manufacture craft comprises the following steps:

1, rice (grain in storage for years) is ground into 50-80 order ground rice through screening impurity elimination dedusting.

2, be that the rice meal of 55-60 weight part and food organism Tapioca Starch that content is the 35-40 weight part add and mix the unit uniform mixing, i.e. 60-80 ℃ of modification dissolving, devolatilization, granulation with content.

3, the particle that compound is made changes the twin screw extruder group again over to, and the required width of extruding is that 100-300mm and thickness are the sheet material of 1.5-3mm under 160-180 ℃ of constant temperature.

4, and then with sheet material molding unit (selecting for use corresponding die needed) under 50-60 ℃ temperature, hot-forming automatically, shear cutting edge, cooling and shaping.

5, after finished product is sterilized with the disinfection by ultraviolet light machine after testing, the packing warehouse-in.

Five, Fa Ming economic benefit and social benefit are

1, belong to the food starch tableware that can automatically degrade, it is a raw material with edible rice grain in storage for years, the biological powder tableware after sterilization to wrap food without any pollution.

2, Biological resources cycling and reutilization, the tableware after using up can be concentrated and put into remaining food bucket, and together as feed, there is not the discarded and waste of Biological resources in processing treatment separately.

3, biological rice (grain in storage for years) starch dishware, dimensionally stable is tall and straight, and is waterproof, uses in-20-150 ℃ microwave oven or refrigerator, indeformable, do not ftracture.

4, biological Starch rice tableware can natural degradation, in the environment that exposes fully, and a degraded in month, degraded in 2 days under seal-packed condition, was not degraded in 6 months in the water, was convenient to preserve.

5, the cost of material is low, easily buying.Try repeatedly to survey, use through us, effect is fine.235 * 180-190 * 35mm split four lattice cutlery boxs (32 restrain), the product export valency is 0.18 yuan as long as (wherein material cost is 0.092 yuan/, 0.048 yuan/of other cost, 0.01 yuan/of tax delivery, 0.03 yuan/of profit after tax).Sales price can be decided according to various countries and market, domestic each department.

Six, embodiment:

Below in conjunction with accompanying drawing and case study on implementation the present invention is described in further detail:

1,,, becomes the biological powder of 50-80 purpose in 600 * 600mm crusher for crushing through screening impurity elimination dedusting with 70 kilograms of rice grains in storage for years.

2, with 16 kilograms in Starch rice tackiness agent, 2 kilograms of edible degradation agentss, 8 kilograms of edible materials Tapioca Starchs all add the mixing unit and stir, and through 60-80 ℃ of modification dissolving, devolatilization is granulated in the parallel parallel dual-screw extruding granulator of TSK-65/44 again.

3, pellet is squeezed into wide 100-300mm through sheet extruder under 160-180 ℃ of constant temperature, the sheet material of thick 1.5-3mm.

4, then sheet material is automatic hot-forming at 50-60 ℃, (in the needed size of corresponding processing, the shape tableware mould), automatically hot-forming, and through the sterilization of disinfection by ultraviolet light machine and along shears cutting edge shearing, cooling and shaping, after quality examination person by (GB18006.1-1999) and (GB18006.2-1999) national standard detect, qualified back packing is put in storage.

Description of drawings: more than be a complete technological process of production figure.
