Product Description

Product Introduction

Product Description   

Drum dryer is a contact-type, internally heated, conductive drying device designed for efficient drying of a variety of materials, such as grain, ore, coal, and sawdust. The rotating motion of the drum evenly distributes the material in the heated airflow, rapidly evaporating moisture. This dryer is favored for its consistent drying performance, energy-saving features, and ease of operation, making it suitable for a variety of industries, including chemical processing, food processing, agriculture, and environmental protection. Customization is also available to meet specific production needs.

Applications  

Rotary drum grain dryers are mainly suitable for various agricultural and cash crops such as rice, wheat, corn, soybeans, sorghum, rapeseed, millet, peanuts, and sunflower seeds. They are widely used by large-scale grain growers, family farms, grain cooperatives, grain purchasing points, township grain stations, large grain depots, feed mills, and grain and oil processing enterprises. They can quickly reduce grain moisture, preventing mold, germination, and pests, meeting the standardized drying needs before grain storage, long-distance transportation, deep processing, and market circulation. They can also be used for seed drying, ensuring seed germination rates, and are suitable for various production models, from seasonal concentrated grain collection to year-round large-scale drying.

Product Advantages  

High Efficiency and Energy Saving: The drum dryer utilizes advanced drying technology and equipment to quickly evaporate moisture from materials, achieving rapid drying results while effectively controlling temperature and humidity to avoid energy waste.
Widely Applicable: The dryer can be adjusted to suit the characteristics of different materials, effectively drying a wide range of materials, from powdered materials to granular materials and bulk materials.
Stable and Reliable: Utilizing high-quality materials and advanced manufacturing processes, the dryer offers excellent durability and stability, ensuring long-term stable operation and ensuring production efficiency and product quality. Environmentally Friendly and Energy-Saving: During the drying process, the dryer effectively controls Exhaust emissions are minimized, reducing environmental pollution while effectively utilizing waste heat and waste gas, achieving energy recycling.
Flexible Handling of Specialty Materials: Rotary drum dryers offer exceptional flexibility, handling a wide range of materials, including solids, pastes, and sludge, making them suitable for industries such as agriculture, mining, and chemicals.
Scalability and Customization: The dryers offer scalability and customization options, allowing for continuous use in harsh conditions. Their rugged design minimizes wear, extending service life, and reducing maintenance requirements.
Emission Compliance: Modern rotary drum dryers are designed with environmental considerations in mind, minimizing emissions.
High Thermal Efficiency: Because the dryer utilizes heat conduction, the direction of heat transfer remains largely consistent throughout the entire heat transfer cycle. Therefore, the majority of the heat supplied to the drum is used to vaporize the moisture in the material, resulting in a thermal efficiency of 80% to 90%.
High Drying Rate: Heat and mass transfer from the wet material film on the drum wall is consistent from the inside out, creating a large temperature gradient, maintaining a high evaporation intensity on the film surface.

FAQ

Q: What materials can a drum dryer dry?

A: 1. Mainstream grains: Wheat, rice, corn, sorghum, soybeans, and other grain crops; suitable for both high and low moisture content grains.

2. Cash crops: Peanuts, rapeseed, cottonseed, and other oilseeds, as well as granular medicinal and edible crops such as goji berries and red dates.

3. Other pellets: Feed pellets, small medicinal herb granules (such as Isatis root).

Q: What are the heat sources for a drum dryer?

A: 1. Biomass heat source (straw, sawdust)
2. Gas/oil heat source (natural gas, diesel)
3. Electric heating
4. Coal heat source
5. Mixed heat sources

Q: How to set the drying temperature for different grains?
A: 1. Heat-sensitive grains (wheat, rice, oats): 35-50℃. For initial moisture content ≤18%, set 35-40℃; for 18%-25%, set 40-45℃; for >25%, pre-dry at 35℃ for 1 hour before increasing the temperature to prevent cracking.
2. Heat-resistant grains (corn, sorghum): 45-80℃. For corn, with moisture content 20%-25%, set 50-60℃; for >25%, set 60-70℃. Soybeans have high oil content; control the temperature at 45-55℃ to prevent oil oxidation.

Q: Grains stick to the inner wall of the drying drum. How to solve this?

A: 1. Pre-dry the grains for 1-2 hours to reduce surface moisture.
2. Preheat the drum to 40℃ with an empty machine before feeding.
3. Increase the hot air volume to accelerate moisture evaporation.
4. Replace small grain particles with baffles with guide grooves to prevent sticking.

Q: What maintenance should be performed on the equipment after each day's use?

A: 1. Clean the drum: Open the inspection door and use a soft brush to sweep away any residual grain from the inner wall and lifting plate to prevent mold and contamination;

2. Remove dust: Remove the dust collector bag and beat it to remove dust; replace any damaged bags promptly;

3. Check components: Check the tension of the drive belt and add special lubricating oil to the bearings (once a month).
