CATHAY dryer, efficient drying of materials, low energy consumption and high quality

CATHAY dryer: efficient drying, enabling material dehydration and volume reduction

1. Multi-dimensional drying technology to achieve deep dehydration

CATHAY dryer integrates hot air convection, conduction heating and intelligent temperature control technology to build a multi-dimensional drying system. After the material enters the drying cylinder (or drying chamber) through the feeding device, it is fully contacted with the high-temperature hot air (the temperature can be adjusted to 60-300℃), forming a fluidized bed or suspension state under the disturbance of the air flow, greatly increasing the heat exchange area. At the same time, the cylinder wall (or stirring paddle) assists in heating through conduction heating, so that the moisture inside and outside the material evaporates synchronously and is quickly discharged through the induced draft system. According to the characteristics of different materials, you can choose the downstream or countercurrent drying mode: the downstream mode is suitable for high temperature resistant materials and has a fast drying speed; the countercurrent mode is suitable for heat-sensitive materials to avoid local overheating. A single device can evaporate 50-500kg of water per hour, and the final moisture content of the material can be accurately controlled at 1%-15%, meeting the drying standards of different industries.

2. Multi-material adaptation, covering the needs of the entire industry

Mining field: Efficient drying of metal ore concentrates (such as iron ore concentrate, copper concentrate), non-metallic mineral powder (kaolin, quartz sand), filter cakes or wet materials from 20%-30% moisture content to 5%-10%, easy to transport, store and subsequent processing, reducing transportation costs by more than 30%.

Agricultural field: Suitable for dehydration and drying of agricultural products such as grain (corn, wheat), fruits and vegetables (peppers, wolfberries), and feed. Low-temperature hot air (60-80℃) is used to retain nutrients. The color of the material after drying is natural, and the shelf life is extended by 3-6 months.

Chemical industry: Processing chemical raw materials such as dyes, fertilizers, and plastic particles can accurately control the drying temperature and time to avoid material agglomeration or component decomposition, ensure product purity and activity, and increase the qualified rate of finished products to more than 98%.

Environmental protection: Drying and reducing the volume of municipal sludge, industrial waste residue, etc., drying wet sludge with a moisture content of 60%-80% to a moisture content of 10%-20%, reducing the volume by 70%-80%, facilitating incineration for power generation or landfill disposal, and reducing environmental pressure.

3. Intelligent temperature control system, precise control of the drying process

Equipped with a PLC intelligent control system, it monitors the moisture content of the material in real time through an infrared moisture sensor, and automatically adjusts the hot air temperature, material flow rate and drum speed in combination with the feedback data of a multi-point temperature probe (error ≤±1℃). The operator can preset drying parameters (such as final moisture content, heating rate) through the touch screen, and the system automatically generates the optimal drying curve, supports remote monitoring and data traceability, and reduces manual intervention. For batch production, it can store drying formulas for more than 100 materials, which can be called with one click when changing materials, and the switching time is shortened to less than 5 minutes.

4. Energy-saving design, reducing operating costs

Waste heat recovery technology: equipped with high-efficiency heat exchangers, the waste heat in the exhaust gas is recycled and utilized, the fresh air temperature is preheated to 80-120℃, the heat source energy consumption is reduced by 20%-30%, and the annual fuel cost is saved by more than 100,000 yuan (taking 10 tons/hour equipment as an example).

Variable frequency drive system: key components such as fans and conveyor belts use variable frequency motors, which automatically adjust the power according to the amount of materials, and the no-load energy consumption is reduced by 40%, avoiding energy waste.

Excellent thermal insulation performance: The drying cylinder wall adopts aluminum silicate insulation layer + stainless steel shell, the heat loss rate is less than 5%, which reduces heat loss by 15%-20% compared with ordinary equipment, ensuring stable temperature in the cylinder.

5. Structural optimization, durability and safety

Wear-resistant and anti-corrosion: The inner wall of the drying cylinder is made of high-chromium cast iron or ceramic coating, which has a three-fold improvement in wear resistance and can handle materials with high sand content; the parts in contact with the material are made of 304/316 stainless steel, which is resistant to acid and alkali corrosion and adapts to harsh working conditions such as chemical and environmental protection.

Safety protection: Equipped with over-temperature alarm, overload protection, and explosion-proof device (for flammable and explosive materials), it complies with national safety production standards to ensure that the equipment is running without safety hazards.

Easy-to-clean design: There is no dead corner in the cylinder, and it supports online cleaning function. When changing materials, residual materials can be quickly cleaned to avoid cross contamination, meeting the hygiene requirements of the food, medicine and other industries.

6. CATHAY brand guarantee, full life cycle service

Each dryer is tested at full load for 72 hours before leaving the factory to ensure that the performance meets the standards. Customized services are provided, and drying plans can be designed according to material characteristics (viscosity, particle size, thermal sensitivity), such as adding a disintegration device (for agglomerated materials) and an inert gas protection system (for easily oxidizable materials). The professional team provides on-site installation and commissioning, operation training, regular maintenance and other services, 7×24-hour technical hotline response, and a 3-year warranty on key components, allowing customers to use without worries.
