Specialized airflow dryer for sawdust
Project Description:
With the development of technology and the scarcity of resources, sawdust (sawdust), as well as various types of straw and edible mushroom residue, have been transformed from discarded waste into usable resources for the production of sawdust products and high burning value biofuels. All of these require sawdust and crushed residue to undergo a drying process. However, many drying equipment on the market are not suitable, and many biomass pellet fuel manufacturers can only maintain production due to low efficiency of drying equipment, poor operation of equipment, and product quality issues, resulting in low profits. Therefore, biomass fuel and charcoal production enterprises are forced to seek professional manufacturing enterprises with high production equipment efficiency and processes. The optimization design of drying equipment should first meet the requirements of producing competitive quality products, followed by investment savings, smooth operation and low maintenance costs of mechanical equipment, high labor productivity, and consideration of labor conditions and environmental protection requirements.
1、 Equipment Overview:
Wood chips (sawdust) are organic compounds with a moisture content of around 40-50%. After drying, they generally have a moisture content of around 12%. Their main moisture is free water and biological water, with free water being easier to remove while biological water is difficult to remove. The drying process of sawdust (sawdust) mainly considers factors such as output size, characteristics of finished materials, ease of operation, one-time investment, and operating costs. At present, most sawdust drying equipment adopts air flow dryer, fluidized bed dryer, and rotary dryer. Among them, air flow dryer and drum dryer are widely used in sawdust drying. Air flow dryer has low investment, 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.
2、 Equipment Description:
The new energy-saving sawdust dryer designed and produced for drying is a drying equipment with a large processing capacity. It is designed and manufactured based on the specific characteristics of sawdust, and analyzes the impact of the dryer structure on the yield, quality, and other aspects of sawdust.
Based on the characteristics of sawdust materials, a technical transformation was 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 were adopted to eliminate the phenomenon of air holes in the materials, allowing sawdust 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 drying machine produced by Jianda has a very obvious advantage.
3、 Equipment features:
Main features of sawdust drying equipment:
1. Automatic control can ensure that the moisture content of the dried wood chips is uniform and stable.
2. Automatic stone and iron removal can ensure that impurities in the dried wood 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 energy-saving, thermally controllable, and easy to operate, reducing coal consumption by up to 60%.
