Abstract
A squeezing, puffing and shaping technology for making degradable dinner set and package filler containing plant fibres asmaterral includes such steps as breaking plant fibres, grinding to obtain power (50-100 meshes), mixing with plant starch and water, squeezing at 140-190 deg.C and 0.5-0.8 MPa and injecting into shaping mould. Its advantage are degradable nature, no environmental pollution high productivity and low cost.
Description
The present invention relates to utilize the crop plants fiber to be raw material, adopt the extrusion moulding process to make tableware, dottle pin article process field.
At present, China's fast food market tableware mainly is stationery and moulds based article.The exploitation of stationery tableware is to mould the discarded back of dishware at long-term a large amount of uses to be difficult for degraded, environment is polluted put forward.Be one and can not be ignored " white pollution " source and mould system industrial packaging dottle pin goods.
In recent years, be that the tableware that raw material is made is come out one after another with the string, it has had both paper, has moulded the advantage of two based articles.The relative paper products of plant fiber products does not consume timber, does not have the black pollution of paper-making pulping process yet, but than paper products degradation speed is faster arranged; Plant fiber products is moulded based article relatively, and degradation property is more completely arranged; The plant fiber products main raw material is crops, and it becomes the raw material of industry, helps the comprehensive utilization of agricultural resource, improves additional value of farm products.So exploitation uses plant fiber products to help protecting environment and resource regeneration.
The production technology of current plant fiber tableware mainly is the hydraulic press single-set operation, hand charge, compression molding.The links such as burr that produce when charging, the demoulding and mold pressing all need manually to handle by part to remove.Although changed hydraulic pressure afterwards is pneumatic, changes hand charge and is mechanically materials device such as weigh, and its energy consumption waste and labour intensity are still very big, and direct result is that efficient is low, the cost height.
In addition, the batching link mainly is glue mixing in string, adds functional waterproof and oilproof auxiliary agent, and forming process is a physical process.Such dinner set product consumption glue amount is big, is of close texture, and structure is hard, and it is soft that feel is owed, and heat-insulating property is poor, and color is difficult for being accepted by the consumer.
The objective of the invention is to utilize the crop plants fiber to be raw material, adopt the extrusion moulding process to make degradable dinner set and packing dottle pin goods.Realized producing degradable tableware and packing dottle pin goods, can improve the die press technology for forming of present production plant fiber products again, realized working continuously, automated production has reduced energy consumption, has improved efficient.
Making plant fiber tableware of the present invention and packing dottle pin goods extrusion moulding process flow process such as Fig. 2
The concrete enforcement of technology of the present invention is as follows: at first with crops, make 50～100 purpose fiber dusts as pulverising mills such as corn stalk, jowar straws, then with this powder and plant amylum and water by 1: (0.25～0.55): (0.25～0.40) weight ratio proportioning becomes material, enters the moulding of extruder extrusion after stirring.
The extrusion shaped device is seen Fig. 1.
The extrusion shaped device is made up of transmission device 1, machine barrel 2, feed arrangement 3, screw rod 4, heater 5, control device 6, nib 7 and shaped device 8.
The material that stirs is a feed zone 1 by the machine barrel 2 that feed arrangement 3 enters screw extruder
1, transmission device 1 makes the extruder screw rotation, and material is pushed ahead with the screw rod rotation and is gradually reduced, by 1
1Section enters 1
2Section is an extruded segment.1
1The thread of section spiral is darker, raw material is entered be full of machine barrel in the extruder.Enter 1
2Section, screw channel shoals gradually, and pitch shortens, and is subjected to the drag effect at head place, and material is by compacting gradually.The internal friction heat that the blending shear forces of material is produced through screw rod, machine barrel and from the effect of machine barrel external heat device 5, material heats up rapidly, boosts, 1
2End becomes the quantitative section 1 of homogenizing that enters machine barrel behind the plastic fluid that dissolves indefinite form fully
31
3Section, because screw channel further dwindles, shearing force sharply increases, fluid is continued increasing temperature and pressure, and physicochemical property changes, under the control of control device 6, last screw rod with plastic fluid constant temperature (140～190) ℃, level pressure (0.5～0.8MPa), extrude the shaped device 8 that is injected into normal temperature and pressure from nib 7 quantitatively, form the expanded green article of certain physical dimension and shape, after surface treatment, promptly become finished product again.
In order to satisfy market demands, increase aesthetic feeling, this plant fiber tableware and packing dottle pin can add edible or industrial colouring agent according to different needs when preparation of raw material, as Masterbatch, to change this color of string.In addition, also can be according to the product design needs, a kind of among 0.5～0.8% blowing agent of the weight that adds materials such as modification Celogen Az and the freon.
The present invention has following advantage and effect:
1, can utilize crop stalk to make degradable dinner set and dottle pin product, be conducive to the agricultural resource comprehensive utilization, improve agricultural product added value, also solve the black pollution problem of " white pollution " and the paper products of plastic products simultaneously.
2, extrusion moulding process of the present invention solves unit hydraulic operation in the present plant fiber tableware production, the automaticity that die press technology for forming exists is not high, shortcomings such as the low and energy resource consumption height of production efficiency, the present invention can realize the production of working continuously automatically, its production capacity can reach 100～130kg/h, installed capacity needs 80～100KW, and type captain's degree is at 20～25m.
3, after material is handled through extrusion, the protein denaturation in the material, microorganism is killed.Because volume of material increases (1.5～2.5 times), inside has produced many microporous sponges soma, and the quality pine throws, and heat insulation property is good, and smooth surface is smooth, and has alleviated about 1/3rd with a kind of product bulk density.
4, the finished product after surface treatment meets food hygienic standard and technical conditions, the results are shown in Table 1.
This product is nontoxic, tasteless, resistance to water, oil resistivity, high-low temperature resistant, chemical proofing meet the relative national standards requirement.Pollution-free, the degradable of this product reclaims capable of using as feed or fertilizer simultaneously.
| Sequence number | Test item | Standard value | Measured value |
