Introduction
Bamboo paper pulping machine is the core equipment that converts raw bamboo into high-quality chemical bamboo pulp, which is further processed into toilet tissue base paper. The global demand for eco-friendly and soft toilet tissue rolls has surged in recent years, and bamboo pulp has emerged as the ideal raw material due to its sustainability, soft fiber texture, and high absorbency.
As a leading manufacturer in China, NRC MACHINE (Qingdao New Richuan Precision Machine Co., Ltd) specializes in designing and producing high-efficiency bamboo paper pulping machine tailored for toilet tissue production. With over 18 years of machinery export experience, our equipment has been exported to more than 80 countries and regions, delivering reliable solutions for tissue production enterprises worldwide.
What is a Bamboo Paper Pulping Machine?
2.1 Definition of Bamboo Paper Pulping Machine
A bamboo paper pulping machine is a complete set of chemical pulping equipment that processes raw bamboo into pulp through cooking and adding caustic soda (sodium hydroxide). This equipment effectively breaks down lignin in bamboo, separates cellulose fibers, and produces high-purity bamboo pulp that meets the quality standards for toilet tissue base paper. Unlike mechanical pulping machines, our chemical bamboo paper pulping machine preserves fiber integrity, resulting in softer and more durable toilet tissue products.
2.2 Core Functions of the Bamboo Paper Pulping Machine
The bamboo paper pulping machine integrates multiple functional modules to complete the entire pulping process: raw material preparation, high-temperature cooking, pulp washing, screening, refining, and dewatering. Its core functions include removing impurities from bamboo, decomposing lignin via chemical reactions, extracting pure cellulose fibers, and adjusting pulp consistency to meet the requirements of subsequent toilet tissue production lines.
2.3 Advantages of Bamboo Pulp for Toilet Tissue
Bamboo pulp produced by the bamboo paper pulping machine offers unique advantages for toilet tissue manufacturing:
- Softness & Absorbency: Bamboo fibers are fine and soft, providing a gentle touch and high water absorbency.
- Sustainability: Bamboo matures in 3–5 years, much faster than wood, making it a renewable and eco-friendly raw material.
- Strength: Bamboo pulp has high mechanical strength, ensuring toilet tissue is not easy to tear during use.
- Cost-Effectiveness: Bamboo is widely available in many regions, reducing raw material costs for tissue manufacturers.
Chemical Bamboo Pulp Production Process Using Bamboo Paper Pulping Machine
The chemical bamboo pulp production process is a systematic workflow executed by the bamboo paper pulping machine, ensuring efficient conversion of bamboo into high-quality pulp. The detailed steps are as follows:
3.1 Step 1: Bamboo Raw Material Preparation
Mature bamboo (3–5 years old) is harvested and cut into uniform chips (10–25mm in size) using a bamboo chipping machine. The bamboo chips are then washed to remove dust, soil, and other impurities, ensuring the purity of raw materials for subsequent pulping.
3.2 Step 2: Cooking with Caustic Soda in Bamboo Paper Pulping Machine
The washed bamboo chips are fed into the digester of the bamboo paper pulping machine, where caustic soda (sodium hydroxide) is added as the cooking chemical. The mixture is heated to 160–180°C under a pressure of 0.6–0.8 MPa for 90–120 minutes. This high-temperature and high-pressure cooking process decomposes lignin and hemicellulose in bamboo, separating cellulose fibers to form crude bamboo pulp.
3.3 Step 3: Pulp Washing & Black Liquor Recovery
The crude bamboo pulp is washed repeatedly in the washing unit of the bamboo paper pulping machine to remove residual caustic soda and black liquor (a byproduct of cooking). Our equipment is equipped with a closed-loop washing system that recycles water and recovers black liquor for energy reuse, reducing environmental pollution and production costs.
3.4 Step 4: Pulp Screening & Refining
The washed bamboo pulp is screened to remove undigested bamboo chips and impurities. Then, it is refined using a disc refiner to further separate and fibrillate cellulose fibers, adjusting fiber length and uniformity to optimize pulp quality for toilet tissue production.
3.5 Step 5: Pulp Bleaching (Optional) & Dewatering
For white toilet tissue, the refined bamboo pulp can be bleached using eco-friendly oxygen-based bleaching agents. Finally, the pulp is dewatered to a consistency of 25–30% using a screw press, forming wet pulp or pulp sheets that can be stored and transported to toilet tissue making machines.
