* * * Similarities:
1. Production of products: These three factories exist to produce specific products. Fermentation factories mainly produce fermented foods or drinks, such as yogurt, beer, soy sauce and so on. The food factory produces all kinds of food, such as bread, biscuits and canned food. Pharmaceutical factories produce drugs and medical supplies.
2. Biological effects: Both fermentation factories and pharmaceutical factories involve biological effects. Fermentation factories use microbial fermentation to transform food, raw materials or waste, and biotechnology is often used in pharmaceutical factories to synthesize drugs.
3. Quality control: These factories should carry out strict quality control in the production process to ensure the safety and quality of products meet the standards.
Difference:
1. Product type: Fermentation factory mainly produces food and drinks, food factory mainly produces food, and pharmaceutical factory specializes in producing drugs and medical supplies.
2. Supervision: Pharmaceutical factories need to follow stricter supervision in the production process, because drugs are directly related to people's health and life. The regulatory standards of fermentation plants and food plants are relatively low.
3. Technology and equipment: The technology and equipment of fermentation plants and food plants are relatively simple, mainly to promote the fermentation and processing of ingredients. The process and equipment involved in pharmaceutical factories are complicated, so it is necessary to ensure the purity and stability of drugs.
It should be noted that the above are similarities and differences in general, and may not be applicable to every specific factory. The scale, technology, product type and other factors of the factory will have an impact on its specific characteristics.
