Wheat Straw Pulp Making Machine

Introduction to wheat straw

Wheat Straw , as the rest of the crop harvest, has long been considered agricultural waste. However, with the improvement of environmental awareness , people began to realize this rich renewable resources. Wheat straw has cellulose, it is a key ingredient in making pulp. Compared with traditional wood pulp, wheat straw pulp not only comes from a wide range of sources, but also has a short growth cycle, which has significant sustainability advantages.

Development prospect of wheat straw pulp

Driven by the global wave of environmental protection, as a renewable and environmentally friendly pulp raw material, the wheat straw market demand shows a steady growth trend. In the international market, the wheat straw continues to grow as the global demand for environmentally friendly papermaking raw materials.

Especially in developed countries with relatively poor resources, The need for renewable resources such as wheat straw pulp is more urgent. These countries care not only about the supply of wheat straw pulp, but also about the quality of wheat straw, which has prompted China’s wheat straw pulp export enterprises to increase production and at the same time, but also increase the strength of product quality control. The various demand of the international market provides a broad scope for China’s wheat straw pulp export enterprises, thus promoting the continuous expansion of China’s wheat straw pulp export scale.

wheat straw pulp manufacturing process

Pre-treatment: The wheat straw is screened, chopped and crushed, it make wheat straw facilitates the subsequent pulping process.

Pulping: Put wheat straw into the pulping tank, add the appropriate amount of lye and water, and The straw fiber is free under high speed stirring to form initial pulp.

Cooking: The initial pulp is added to the pulp digester, and the lye and other auxiliary agents, make the initial pulp take place a chemical reaction under high temperature and pressure so that the fiber is easier to separate and better quality pulp is obtained.

Bleaching: The boiled pulp is bleached and removes impurities. Finally, get a purer pulp.

Washing: The bleached pulp is washed to remove the residual lye, bleach and other components to obtain the final pulp.

Concentration: Concentrate the screened stock and adjust its concentration for easy storage and transportation.

wheat straw pulp mill

hay cutter and kneading machine

The main use of hay guilloff kneading machine in paper mill is to crush wheat straw and grass and other fibrous materials as raw materials for paper making. ‌ Hay guilloff kneading machine is suitable for crushing corn straw, cotton stalk, peanut seedlings, weeds, branches and other fibrous rod materials, the fineness of crushed materials can reach 2mm or less.

Pulp Digester

At the digester, wheat straw is subjected to heat, pressure, and chemicals to break down the lignin and separate the cellulose fibers. A rotary ball digester is a commonly used pulping equipment especially suitable for wheat straw pulping. By rotating spherical structure, this equipment can cook wheat straw under high temperature and pressure, which can effectively separate and brush the fiber. It improves the pulping efficiency. The rotary spherical digester is high efficiency, energy saving, and environmental protection, which is suitable for large-scale production.

Screening Machine

It is used to separate pulp from non-fibrous materials and residual straw particles. large impurities and non-conforming materials are removed from the straw. The purity and quality of pulping are ensured by screening processes.

Washing Machine

The pulp is washed to remove any remaining chemicals and impurities. The washing system is widely used in the cleaning and purification of wheat straw, reed, bagasse and other raw materials. It can effectively remove impurities such as mud and sand to improve the cleanliness of raw materials. The raw material can better play its fiber properties role in the subsequent pulping process after washing, which improves the quality and production efficiency of the pulp.

Bleaching Machine

In the COH bleaching process, after the chlorination stage (C stage) in the traditional CEH bleaching process, the oxygen delignification stage (O stage) replaces the traditional alkali treatment stage (E stage), thereby it reduces the consumption of sodium hydroxide and the emission of pollutants during the bleaching process. This way can not only get high whiteness, low kappa numbers, and good physical properties of pulp, but also can reduce the amount of chemicals. so it could achieve the goal of cheap and clean bleaching.

The advantage of AGICO Group

High efficiency and low consumption

Compared with traditional pulp equipment ,the work efficiency of this wheat straw pulping equipment is increased by more than 50% ,electricity consumption is reduced by 30-40%.This means the equipment is able to process more the wheat straw while consume less electricity. Thus this reduces cost of production.

High pulp yield and good pulp quality

The wheat straw pulping equipment efficiently turn the wheat straw into good pulp quality by cleaning, cooking, grinding, screening and other processes.these pulp well perform in the paper making process and could meet the needs of high quality paper production

high degree of
automation

Wheat straw pulping production line has a high degree of automation, which greatly simplifies the operation process, reduces manual intervention, and improves production efficiency. The automated system ensures the stability and consistency of the production process, thus ensuring the quality of the pulp.
