Product Description

The PLC controlled rotary drum dryer is an intelligent industrial drying equipment that integrates a high-precision PLC automatic control system on the basis of traditional rotary drum dryers. It can realize full-process automatic adjustment of drying parameters, avoid manual operation errors, and ensure the stability and consistency of drying effects. It is widely used in high-standard, high-automation drying production scenarios in industries such as new energy, fine chemicals,

Working Principle

The PLC control system centrally collects real-time data such as drum rotating speed, hot air temperature, material moisture, feeding speed and exhaust gas humidity from each sensor node. According to the pre-set optimal drying process curve, it automatically adjusts the operating parameters of the transmission system, heat source system, feeding and discharging system in real time. The materials are accurately controlled to stay in the drum for the optimal time, fully and uniformly exchange heat with the hot air at the set constant temperature, and the moisture is precisely evaporated to the target value. The whole process does not require frequent manual intervention, realizing the fully automatic, intelligent and stable drying operation.

Key Features

• ‌High-precision automatic control‌: The temperature control accuracy can reach ±1℃, the material residence time error is less than 1%, and the moisture uniformity of finished materials is controlled within ±0.2%.
• ‌High degree of intelligence‌: It supports one-key start, automatic fault diagnosis, operation data recording and remote monitoring, which greatly reduces the labor intensity of on-site operators.
• ‌Stable and consistent product quality‌: It completely avoids the quality fluctuation caused by human misoperation, and the product qualification rate is increased by more than 15% compared with that of manually controlled dryers.
• ‌Strong process adaptability‌: Multiple sets of drying process curves can be pre-stored, and one-key switching can be realized when changing different materials, which is very suitable for multi-variety and high-standard production demands.
