A reasonable layout for an Organic fertilizer equipment manufacturers should comprehensively consider production efficiency, environmental protection requirements, safety regulations, and future development needs. Specific design principles and recommendations are as follows:

1. Clear functional zoning: Office and living areas should be located upwind of the main wind direction and maintain a certain distance from the production area. These areas can be separated by green belts to minimize the impact of odor on these areas. The fermentation area should be located away from environmentally sensitive areas such as residential areas, and a boundary sanitary and environmental protection distance should be established. Finished product storage areas should be located near packaging processes for convenient storage and transportation.

2. Smooth logistics and system integration: Building, equipment, and process connections should be used to integrate various functional areas into an organic whole. The layout of raw material storage, pretreatment, fermentation, and finished product areas should be as compact as possible to minimize the distance and time required for material transportation.

3. Environmental protection and pollution control: The fermentation and pretreatment areas should be equipped with exhaust gas treatment equipment, such as biological deodorization equipment or high-pressure spray deodorization facilities, to reduce the emission of malodorous gases. The plant should implement separate drainage systems for rainwater and sewage, and production wastewater should be treated before discharge or reuse. Dust-generating processes such as crushing and screening should be equipped with dust removal equipment. Green belts should be established around the plant and between functional areas to effectively reduce the spread of odor and dust.

4. Consider future development: When designing the master plan, allow for expansion space to allow for future capacity expansion or equipment upgrades based on the needs of the organic fertilizer production line and technological developments.

The above layout principles and recommendations can ensure a rational, efficient, and environmentally friendly and safety-compliant layout for the organic fertilizer equipment plant.
