PPDM extraction method for agriculture waste straw fibre

Abstract

The invention relates to a technique for PPDM extracting the agricultural wasted straw fiber, belonging to the straw fiber extracting technical field. The technique for PPDM extracting the agricultural wasted straw fiber comprises the following steps of the detecting, the cutting, the dipping and washing, the boiling, the thread rolling, the pressing, the mixing, the accurate grinding, the filtering and screening and the bleeding. The technique has the advantages that: 1. the pesticide residue is processed by dipping, washing and boiling; 2. the invention studies the constant boiling temperature and the boiling time; 3. an underground low-pressure concrete boiling pool is adopted, a cylinder mould is adopted to charge materials arranged by three rows. The technique saves water by more than 70 percent compared with the soda boiling fiber breaking technique, eliminates waste water, absorbs and digests the organic domestic garbage for protecting the environment; meanwhile, the technique adopts the marsh gas technique to exploit and adopt the new energy, the water can be used repeatedly completely, the electric energy is saved, the investment is saved and the security is high.

Description

1. Technical field [0001] The invention relates to a technology for extracting agricultural waste straw fibers by PPDM, and belongs to the technical field of extracting straw fibers. 2. Background technology [0002] At present, with the development of society and the progress of human civilization, people's awareness of pursuing health and environmental protection is becoming stronger and stronger. Rational use of resources and protection of resources are also one of the basic national policies of governments of all countries. Especially in recent years, people's demand for healthy and safe food and food packaging materials has become stronger and stronger. Western developed countries have already adopted various compulsory measures in catering and other aspects to ensure the quality of healthy and safe food and its packaging materials. Applied environmental standards require a series of regulations. Our government is becoming more and more strict on environmental law enfo...

Problems solved by technology

[0005] The production process of alkaline cooking cannot maintain the natural original color of plants, and a large amount of sewage is produced through bleaching and decolorization, and there are certain chemical residues in the plant pulp, which cannot meet the hygienic requirements for raw materials required for making green and environmentally friendly products

[0006] Steaming balls and cooking pots, because they are pressure vessels, are dangerous, and must be inspected once a year, and the cost is high; and because the volume pressure is limited, the amount of cooking materials is small each time, and the number of times of feeding and discharging increases, which wastes heat sources; The steaming ball needs to be erected to rotate the space, and the material needs to be conveyed and loaded by electric motor. In order to be heated evenly during cooking, the electric steaming ball needs to be rotated for a long time, which increases the power consumption and increases the investment.
