1、 Overview:
Bamboo chips are an organic compound with a moisture content of around 40-50%. After drying, their moisture content is generally around 12%. The main moisture content is free water and biological water. Free water is relatively easy to remove, while biological water is difficult to remove. The drying process of bamboo chips mainly considers factors such as output size, characteristics of finished materials, ease of operation, one-time investment, and operating costs. At present, most bamboo chip drying equipment adopts air flow dryer, fluidized bed dryer, and rotary dryer. Among them, air flow dryer and drum dryer are the most widely used in bamboo chip drying, and the investment of air flow dryer is the most economical, especially when the output is small. However, due to the extremely short drying time of air flow dryer and the inability to classify the coarse and fine, it is easy to produce unstable moisture after drying, which is prone to blockage and unreliable operation, resulting in the inability to match the rear equipment, causing waste of investment and energy.
Nowadays, there are also many methods that use drum and airflow to dry bamboo chips. However, most of the rollers use single rollers, which occupy a large area and have poor insulation properties. In addition, bamboo chips are unevenly distributed on single rollers, and there is no coarse and fine material grading drying device, which often leads to instability. The most common issue is that the final moisture content cannot be controlled properly, either too dry or too wet. Causing the subsequent process to malfunction, sometimes good and sometimes bad. In addition, bamboo chips contain a small amount of impurities such as stones and iron nails. If the equipment is not properly handled, it can cause frequent damage to the equipment, resulting in equipment fires, explosions, and other phenomena.
Jiangsu Jingjiang Wantai Machinery Manufacturing Co., Ltd. is the only enterprise in China specializing in the design and manufacturing of bamboo chip drying equipment. It has introduced the new technology of multi-layer sleeve bamboo chip drying machine from Germany and applied for a patent.
The new energy-saving bamboo chip specialized dryer designed and produced by Wantai Company is a drying equipment with a large processing capacity. It is designed and manufactured based on the specific characteristics of bamboo chips, and analyzes the impact of the dryer structure on the production and quality of bamboo chips.
Based on the characteristics of bamboo chip materials, a comprehensive technical transformation has been carried out on the dryer to improve the filling rate of materials and the residence time of materials in the cylinder. A new type of combined lifting device and multi-layer sleeve structure have been adopted to eliminate the phenomenon of air holes in the materials, allowing bamboo chips to fully exchange heat and dehydrate; And a coarse and fine particle separation device has been added, greatly improving the heat utilization rate and also increasing the yield; Under the same investment conditions, the advantages of drying machines produced by Wantai are very obvious.
After being used by multiple biomass pellet enterprises in Taicang, Jiangsu, Huzhou, Zhejiang, Jiangxi and other places, it has superior performance and low energy consumption, with a drying wood consumption of less than 100 kilograms per ton of dry bamboo chips. If large bamboo roots and bark are sieved out, the fuel required for basic drying is not much. After the fifth renovation, the performance and quality have become superior, and the environmental friendliness of the machine has been greatly improved, making it more environmentally friendly and energy-saving.

2、 Main features of the equipment:
Main features of bamboo chip dryer:
1. Automatic control can ensure that the moisture content of the dried bamboo chips is uniform and stable.
2. Automatic stone and iron removal can ensure that impurities in the dried bamboo chips do not enter the subsequent process.
3. The investment required for the equipment is 1/6 of that for imported products from abroad.
4. The self insulation thermal efficiency of the cylinder can reach over 70% (the thermal efficiency of traditional single cylinder dryers is only 35%), increasing the thermal efficiency by over 50%.
5. Adopting tail transmission, the transmission is smoother and more reliable; Thoroughly change the phenomenon of the idler wheel frequently slipping and affecting production.
6. Reduce land occupation by about 50% compared to a single drum dryer, lower civil engineering investment by about 50%, and reduce electricity consumption by 60%.
7. Multiple circumferential feeding combinations are distributed to effectively regulate the drying time. Good drying effect.
8. The final moisture content can be easily adjusted according to user requirements.
9. By using frequency conversion speed regulation to control material flow, the desired final moisture index can be easily adjusted according to user needs.
10. The exhaust temperature is low, and the dust removal equipment is used for a long time, allowing for continuous production for the next process.
11. Equipped with a new energy-saving hot air stove, it is efficient, energy-saving, thermally controllable, and easy to operate, reducing coal consumption by up to 60%
