Abstract

A process and its special-purpose apparatus for preparing the disposable chopsticks from the stem and leaf of plant are disclosed. Its preparing process includes such steps as drying the said stemks and leaves, pulverizing, mixing with adhesive, squeezing to obtain plate or strip, cutting to required size, fixating shape, and baking at 150-200 deg.C for 5-10 min.

Description

Make the method and the specific equipment thereof of throwaway chopsticks of plant stem-leaf

The present invention relates to a kind of method and specific equipment thereof of making throwaway chopsticks of plant stem.

Existing throwaway chopsticks all adopt timber to make, and timber resources is caused great waste, and environment is produced ill effect.And on the other hand, a large amount of plant stem-leafs (as straw, careless bar) that proportion of crop planting produces etc. are often burned as waste, and not only contaminate environment also is a kind of waste to resource.Still not having a kind of method and specific equipment at present can make full use of plant stem-leaf, is made into the throwaway chopsticks that satisfy service requirements, to reduce the waste to timber resources.

The purpose of this invention is to provide and a kind ofly make the method and the specific equipment of throwaway chopsticks with plant stem-leaf, make it can make full use of depleted farm crop cauline leaf, the throwaway chopsticks that cost of manufacture is cheap, can satisfy service requirements are protected the limited forest reserves.

Method of the present invention realizes through following steps:

The first step, the exsiccant plant stem-leaf is pulverized, to granularity be 120 orders～180 orders, add weight ratio and be 15%～20% binding agent, stir it (binding agent is nontoxic composition, generally adopt Dian Fentang, polymine, phthalic anhydride and an amount of water formulated);

Second step is 7 * 10 ⁵～10 * 10 ⁵Under the squeeze pressure of pa, the raw material extruding that the first step is obtained is a plane tabular, perhaps uses extrusion equipment that above-mentioned raw materials is extruded and is strip, the tabular or strip material excision forming that will obtain again;

In the 3rd step, with product pressure holding typing and the oven dry of pressing plate with excision forming, bake out temperature is 150 ℃～200 ℃, and drying time is 5～10 minutes, packs at last.

Specific equipment of the present invention comprises a hopper, level is equipped with some to the extrusion roll by the motor transmission after the outlet of hopper, level is equipped with a rolling cut roller behind extruding Kun, be used for the moulding of board-like material rolling cut, level is a stoving oven and the calibrator that is installed in the stoving oven that has heating unit behind the rolling cut roller, this calibrator comprises upper and lower two cover sprocket wheels and is installed in the caterpillar typing press strip of the cover of two on the sprocket wheel that the back level of stoving oven is a package mechanism.

Below in conjunction with the structural representation of the given specific equipment of the present invention of accompanying drawing, to of the present invention

Embodiment is described further:

The first step is pulverized the exsiccant plant stem-leaf, to granularity be 150 orders, add weight ratio and be 15% binding agent, it is stirred.The weight ratio of each composition is in the binding agent: Dian Fentang 3%～10%, polymine 35%～45%, phthalic anhydride 8%～12%, water surplus;

Second step added the hopper 1 of diagram specific equipment with the raw material after stirring, and the raw material of being sent by hopper is squeezed into plane tabular for 2 three times through extrusion roll, and (extrusion roll pressure is adjusted into 9.8 * 10 ⁵Pa), again by between the upper and lower two cover typing press strips of sending into after the 3 rolling cut moulding of rolling cut roller in the stoving oven 45;

In the 3rd step, two cover typing press strips 5 are finalized the design the product pressure holding of rolling cut moulding up and down, and are heated oven dry in course of conveying, and the temperature of stoving oven is controlled at 200 ℃, by adjusting the transfer rate of sprocket wheel 6, guarantees that drying time is 5 minutes.Product warp after the oven dry shoe film roller and the heat-sealing roller of level is later packed.

By the throwaway chopsticks that method of the present invention and specific equipment are made, bright and clean solid, through the reality test, its breaking force can satisfy service requirements fully greater than 200g, substitutes existing wooden throwaway chopsticks, has reduced the waste to timber resources.

Claims
