PSD series fully open dynamic rake dryer is a kind of efficient intermittent drying equipment, widely used in chemical, pharmaceutical, food and other industries. Through the rake stirring and heating of the material, the material is dried under vacuum or atmospheric pressure, and has excellent drying effect. The material contact part of the rake dryer can be 304, 316L, TA titanium alloy, C276 Hastelloy.

First, PSD series fully open dynamic rake dryer - working principle

The device uses a jacket and internal rake teeth to heat the material by conduction while removing evaporated water or solvents through a vacuum pump. In the drying process, the rake teeth constantly stir the material, increase the efficiency of heat and mass transfer, and prevent the material from caking or excessive drying. Because the system is in a vacuum state, the evaporation temperature is low, which can effectively protect heat-sensitive materials.

Second, PSD series of fully open dynamic rake dryer has a number of advantages, improve the operation convenience and safety of the equipment, the specific advantages include:

### 1. ** Easy to clean and maintain **

The fully open dynamic rake dryer door opening device enables the equipment to be cleaned quickly and easily after use, especially for the pharmaceutical and food industries with hygiene requirements. When cleaning, the front or side of the entire equipment can be opened directly, and the operator can fully access the inside of the equipment to ensure thorough cleaning and reduce residue pollution.

### 2. ** Speed up loading and discharging **

The fully open door design significantly speeds up the material loading and removal process. After opening the door, the large area of the feed or discharge port improves the processing efficiency of the material, especially for the more viscous and difficult to flow materials, which is easy to operate quickly by manual or automated equipment.

### 3. ** Improve operational safety **

The door opening device is usually equipped with multiple safety locks and limit switches to ensure that the device will not misoperate and start when the door is opened. This can prevent safety accidents caused by misoperation and ensure the safety of operators.

### 4. ** Easy to check and monitor **

After opening the door, you can quickly check the inside of the equipment, including checking the dry status of the material, the wear of the rake teeth, and the internal cleanliness. This feature is particularly important for processes that require strict quality control during production.

### 5. ** Improve work efficiency **

By simplifying open door operation and reducing maintenance and cleaning time, fully open door devices can improve overall production efficiency, especially when frequently changing materials or products, reducing non-production time.

The all-open dynamic rake dryer device manufactured by Jiangsu Bohong greatly improves the operability, convenience and safety of all-open dynamic rake dryer, making it adapt to the needs of efficient production and sanitary conditions in various industries.
