Designed according to the principle of doubling, the use of dry thermal media to make the solid particles dry in the fluidization state is a fluidized bed dryer, also known as the boiling bed dryer.
The FG series fluidized bed drying granulator, as an important process and equipment for the production of solid -system agents in the pharmaceutical industry, realizes mixed grains and dryness of the raw auxiliary materials; or dry the wet particles obtained by the wet method mechanism. The PLC automatic control system is adopted, and the equipment and technology meet the current GMP and national pharmacopoeia requirements.
The working principle of boiling (granular) dryer
Material powder particles are boiling and fluidized in the raw material container (fluidized bed). They are hydrated and mixed after purifying heating air. Due to the continuous drying of the material by thermal air, the water in the group is evaporated and the adhesive solidifies. This process is repeatedly carried out to form an ideal and uniform multi -porous ball -shaped particles.
Features of boiling (granular) dryer equipment
1. Entry air air treatment unit
Entry -air air treatment unit contains initial efficiency G4, medium -effect F8, high -efficiency H13 three -level filter, high temperature control accuracy, input air flow control through frequency frequency frequency of fan, can be set and adjustable.
2. Host structure
The host contains the bottom cylinder, the moving warehouse, the fluidization warehouse, and the expansion room (or the filter room); the bottom tank, the mobile warehouse and the fluidized warehouse are used by the silicon rubber expansion and sealing ring, and the compressed air detection function is Reliable seal.
3. Product filter
The double -shaking bag anti -static cloth bag filter (or a stainless steel anti -blow filter can be used when there are special requirements) and the filter room is used between the rubber expansion sealing ring, and it has a compressed air detection function to ensure that the seal is reliable. The exhaust pipeline designs the dust sensor and links with the PLC control system to ensure the safety of the product's product.
4. Evaluating air treatment unit
The exhaust system can be designed to select the dust collection system in accordance with the requirements to ensure environmental protection requirements.
5, 2BAR and 10Bar dust storm design
You can choose 2BAR or 10BAR dust storm design, guarantee personnel, equipment and environmental safety, and reliable ground.
6. Freshlyclass bed granules
When requiring the dried granules of the fluidized bed, provide a adhesive stirring tank and a peristaltic pump spray gun system, inject the adhesive into the material through the spray gun, and spray the atomization to the surface of the material under the action of compressed air; the granules of the material; Breaking the bridge through adhesives to form maternal particles, gradually growing up to form wet particles that meet the requirements, and dry the adhesive to get uniform dry particles under the action of hot air.
7. Missing system
It can provide the whole unit of the online drying method to improve the overall unit, or the vacuum -free online unit, to achieve dust -free production, which meets the
current GMP dust -free production requirements.
