Abstract

Straw containing sugar, such as sugarcane (including bagasse), corn stalk adn sorghum stalk, as material is crushed, mould pressed at certain temperature and pressure for certain period, waterproof treated and disinfected to produce the food and sanitary utensil. Without water, supplementary material, adhesive and additive added, the present invention has simple production process and low cost.

Description

Make the method for degradable disposable food, sanitary ware with straw containing sugar

The present invention relates to a kind of usefulness and contain the method that sugared straw is made degradable disposable food, sanitary ware.

Before the present invention, people have made many effort in order to reduce white pollution, adopt papery or with crop stalk or wheat bran, etc. raw material produce apparatus such as disposable tableware, packaging for foodstuff, as application number be 91108365.0, the applying date is 911212, name is called the patent of " disposable tableware and foodstuff package capable of using as feed and manufacture method thereof ", though played effect to solving white pollution, but complex procedures, in process of production, need Jia Shui, add adhesives and additive, productive costs is increased.

The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and need not prepare burden, need not add the manufacturing degradable disposable food of adhesives, water, the method for sanitary ware.

The object of the present invention is achieved like this: a kind ofly make the method for disposable foodstuff, amenities with straw containing sugar, its raw material is that the straw that contains sugar is sugarcane (comprising bagasse), cornstalk, sorghum rod etc., its manufacture method:

The straw drying that 1, will contain sugar;

2, will contain sugared straw is ground into microgranular or powdery;

3, with mold heated to 120 ℃～250 ℃;

4, after mold temperature reaches setting value, at 2～50kg/cm ²Compression moulding under the pressure;

5, the product after the moulding stopped 5 seconds～10 minutes in 120 ℃～250 ℃ mould, took out product then;

6, on the product after the moulding, can spray the thick waterproof layer of one deck 0.01～0.1mm.Its waterproof layer can be food grade coating or covering one deck food grade plastic sheeting, but can adopt the food grade plastic sheeting for sanitary ware, and the letterweight that also can will have water resistance when moulding gets on;

7, to the food utensil disinfection of moulding.

Adopt the present invention to produce that degradable once is edible, sanitary ware, technology is simple, need not add adhesives, additive and water, thereby productive costs is reduced greatly; And to can be with bagasse be that the employment of changing the line of production of small paper mill that raw material is produced paper finds a way out.

Be described in further detail as follows below in conjunction with embodiment:

Embodiment 1 is that raw material is produced the disposable food apparatus, its manufacture method with bagasse: with the bagasse oven dry, after the oven dry, be ground into the fine particles that is similar to powdery; Bagasse is after crushed injected mould; With mold heated to 120 ℃～160 ℃, at 2～10kg/cm ²Pressure under compression moulding, under the said temperature condition, stay mould 5 seconds～5 minutes after the moulding, take out product after, cover last layer and be not more than the thick food grade plastics of 0.1mm, after the ultraviolet radiation sterilization, carry out sealed package.

Embodiment 2 is a raw material with corn stalk or the sorghum rod that contains sugar, produce disposable washbowl, its method is as follows: its straw containing sugar is carried out drying, be ground into the particulate that is similar to powdery after dry the doing, inject mould, with mold heated to 160 ℃～250 ℃, at 10～50kg/cm ²Pressure under compression moulding, and under said temperature, stay mould 1～10 minute, take out product after, be coated with the water-reducible finish that last layer is not more than thick nontoxic, tasteless, the heatproof (more than 120 ℃) of 0.1mm, good stability.
