01 For the alcohol extraction and alcohol precipitation of the workshop, the explosion-proof of the workshop should be considered
Due to the explosion of the pool, the width of the extraction workshop should not be designed too wide. Equipment that needs to take explosion-proof measures should be arranged as close to the outer wall as possible, and the electrical switches in the explosion-proof area should be explosion-proof.
02 The workshop produces heat and moisture, and heat and moisture removal should be done well
The workshop design should consider reserving space for future development. The floor, walls and ceiling of the workshop should be resistant to acid and alkali corrosion and mildew. Lamps and switches in the heat and moisture generating area should be waterproof, and heat and moisture generating equipment should be arranged as close to the outer wall as possible.
03 The transportation volume of the extraction workshop is large, pay attention to reducing labor intensity
The extraction workshop has a large amount of medicinal materials. In order to facilitate management and transportation, the raw medicinal material warehouse, clean medicinal material warehouse, and medicinal material pre-treatment and extraction workshop are generally built in a joint building or in one building. In order to reduce labor intensity and ensure safety, the transportation of raw medicinal materials and clean medicinal materials should be carried out by elevator, and the extraction feeding should be set up with a feeding layer or vacuum suction, and the slag discharge should be set up with a slag discharge room.
04 Post-processing process of concentrate
The concentrate should be refined in a 300,000-level clean environment. The clean area design should meet the requirements of GMP specifications. The workshop should have a cold storage to store the concentrate. If a cold storage is set up in the clean area, a clean buffer room should be set up at the entrance of the cold storage.
05 Extraction of toxic medicinal materials
Special equipment should be set up for the extraction of toxic medicinal materials, and the extraction should be carried out in a special area to prevent cross contamination.
