1, FG series boiling dryer - equipment use

FG series boiling dryer is a multi-functional drying equipment that integrates mixing and drying. It adopts fluidized bed drying technology to achieve fast drying process requirements. The boiling dryer is a device for the production process of solid preparations in the pharmaceutical industry, and has various functions such as mixing and drying. The boiling dryer is suspended in a fluidized state by using a hot air stream purified by air filtration, and is rapidly dried by heat, and the water is evaporated and then removed with the air flow. It is suitable for rapid drying of granules and powder materials in the pharmaceutical, chemical, food and other industries. Applicable to many varieties, multi-dosage and large-scale production needs in the pharmaceutical, food, chemical and other industries.

2, FG series boiling dryer - equipment principle

The boiling dryer consists of a main engine, an air treatment system, a heating system, a control system, and the like. When working, the material is added to the hopper of the boiling dryer, and the program and parameters are set according to the process requirements, and the whole machine starts to work. The air is filtered by the air treatment system, and the filtered clean air is heated by the heat exchanger convection to raise the air to a certain temperature. After the air is heated by the heating system, the fan enters the host machine, and the hot air passes through the distribution hole and the negative hole of the hole mesh plate. Under pressure, the material forms a boiling state in the dryer, and the hot air is in extensive contact with the material. In the large-area gas-solid two-phase contact, the water in the material (solid phase) evaporates quickly and is carried away along with the exhaust pipe. In a short period of time, the water in the material is evaporated and separated to achieve the purpose of drying the material.

The boiling dryer has reasonable structure, stable performance and convenient operation. There is no dead angle in the whole machine and no exposed screws. It adopts PLC automatic control, all operations are automatically completed according to user requirements, and all process parameters can be printed. The original record is true and reliable. Full compliance with GMP and FDA requirements for pharmaceutical production.

3, FG series boiling dryer - equipment features

1. The circular structure in the fluidized bed avoids dead angles, so that the materials are dried in time, and the materials do not stick to the wall of the barrel.

2. The hopper can be equipped with a stirring device to avoid agglomeration of wet materials, especially dust particles due to electrostatic adsorption.

3, the drying speed is fast, the drying process temperature can be strictly controlled to fully guarantee the quality of the material after drying. Manually flipping and unloading is convenient, quick and thorough, and the automatic entry and exit system can be designed as required.

4. Pneumatic pulse back-blowing device: The dust-removing method of dust-removing filter adopts pneumatic pulse back-blowing method, and alternate-type gap back-blowing, so that the dust on the dust-removing cylinder is detached, and the good gas permeability of the dust-removing cylinder is ensured.

5. It can be interfaced with high-efficiency wet granulator and rocking granulator. It is carried out in a closed vacuum system. The wet material (powder and granules) is sucked into the room for drying by negative pressure, effectively avoiding dust leakage and material multiple times. Transfer.

6. The equipment is designed according to the 2bar pressure standard, and the whole machine has a good local work. Top-mounted or side-mounted explosion-proof devices are safe and reliable. PLC intelligent control, high degree of automation, easy operation and maintenance.
