Dryer is widely used in food, feed, chemical, pharmaceutical, mining and other industries.
Before and after treatment
Straw dryer, widely used in corn stalks drying, soybean straw drying, cotton straw drying, wheat straw drying, sorghum straw drying, wood drying, shaving drying, sawdust drying, ginkgo biloba drying, Mulberry leaves drying and other agricultural cellulose materials drying.
Equipment can be used for hot convection heating, steam can also be used for conduction heat transfer. Drying speed, drying strength, short stay time. Fully automatic control, smooth and reliable operation. Coal-fired system using fuzzy controller, the temperature can be automatically controlled to ensure the quality of drying products. Safe production and reliable operation. Multi-stage waste heat recycling system, integrated thermal efficiency increased by 10% or more, so that drying costs greatly reduced.

Straw dryer work flow:
Step 1: wet straw through the grinder, feed scraper belt machine, hot air through the hood, both from the dryer head into the same direction to run back from the tail, called the cis (and) flow baking Dry process; in the cylinder, the material and hot air full contact with the mixing, the hot and humid exchange:
Step two: high temperature air will heat transfer to the wet material, so that wet material temperature,
Step 3: wet material heated to heat up, the water contained in the heat discharged to the hot air, in order to achieve the drying of the wet material; cylinder within the double-board, constantly scraping the material, so that the material and hot air Full contact, promote the heat exchange, and make the material from front to back;
Step 4: After drying the dry residue through the sealed discharge scraper belt conveyor exhaust drying rotary cylinder, and then by artificial packaging, the exhaust gas is treated by the dust removal device from the chimney into the atmosphere.
Straw dryer structure: The straw dryer used in this process is a large continuous drying equipment, the whole set of equipment from the coal-fired hot stove, into the material equipment, rotary cylinder dryer, dust removal system, finished Warehouse, electronic control system, steel frame and other equipment and institutions.
The technical parameters and technical parameters and structure selection and design of the straw drying production line of Jiulong are based on the careful analysis and production practice of the physical and chemical properties of the straw material, and adopted a series of original Of the unique new technology, new technology and new equipment, a good solution to the drying process of various problems, and achieved good drying effect.
Straw dryer features:
1, the precipitation is large, the maximum precipitation range can reach 85-10%.
2, large capacity, a single set of equipment up to 10 tons (precipitation range of 85-12%).
3, high thermal efficiency, low energy consumption, the average amount of 1 ton of precipitation per ton of coal is not more than 176kg standard coal (continuous production, and the ambient temperature ≥ 5 ℃).
4, adaptability, in addition to drying straw can be used, but also for alcohol bad, forage, apple pomace, fresh bean dregs, compound fertilizer and other scattered poor, large precipitation material.
5, the design and manufacture of components are considered in the long-term high temperature conditions to ensure that the mechanical performance requirements, to ensure long-term continuous full load state of the drying operation.
6, the use of mechanical chain-type coal-fired hot air stove as a drying system of heat source, the coal-fired hot air furnace on the coal to adapt to the ability of the stepless variable speed drive, coal combustion is fully complete, hot air furnace overall thermal efficiency Up to 80% or more. On the coal and slag are mechanized operations, stable operation, easy to operate.
7, the use of rotary cylinder dryer as the host of the drying system, simple structure, less failure, low maintenance costs, production capacity, and can guarantee a long continuous operation.
8, in the drying system at high and low temperature pipelines were installed with temperature measurement sensors and digital display instruments, to achieve the best drying effect and to ensure the safe operation of the system.
9, the use of scraper feeder, the use of variable speed transmission, according to the level of material moisture to facilitate the adjustment of the amount of feed.
10, rotary cylinder dryer with stepless variable speed drive, according to the level of material moisture and the amount of feed and easy to adjust the speed of the drum to achieve the best drying effect.
11, in the drying rotary cylinder with a specially designed strong blower, can effectively solve the sticky material in the drying process of bonding and winding and other issues, improve the drying effect.
12, using a unique double copy board structure, to ensure that the dryer drying effect.
13, the use of new and unique sealing device, and with a good effect of the insulation system, effectively reducing the drying system of coal consumption.
14, the overall system sealing performance is good, and with a complete dust removal device, no dust spill, good working environment.
15, the entire drying system using electrical centralized control, hot air temperature automatic adjustment, a high degree of automation, easy to operate.
