Design, layout, and construction of laboratories for agricultural product inspection and testing institutions

As an agricultural country, the safety of agricultural products has always been a concern for all sectors of society. The agricultural residue testing laboratory also plays an important role in food safety and detection of contaminated residues in agricultural products. Agricultural product testing laboratories can cause significant environmental pollution due to the use of large amounts of organic and inorganic chemical reagents, as well as highly toxic chemicals. Therefore, laboratory construction should be located away from residential areas. Considering the ventilation requirements and energy conservation of the laboratory, it should be an independent building, preferably a multi story building. If it is a shared building, it should be located at the top of a multi story building, especially a high-rise building. This will save a lot of resources and energy in the ventilation design and use of the laboratory, and the ventilation effect will be better.

Due to work requirements, the agricultural product testing laboratory can set up the following parts:

Business sample collection room, sample storage room, sample processing room, reagent storage room, sample testing pre-processing room, instrument analysis room, weighing room, drying room, standard solution preparation room, sensory analysis room, quality analysis room, microbiological testing room, genetically modified ingredient testing room, food toxicology analysis room, etc. Each section has basic and special requirements. The business sample room mainly deals with customers, receives samples and sends test reports, handles customer complaints, and is the window for laboratory work. It should be located on the first floor of the building near the entrance hall or in the middle hall of each floor. In short, everything should be based on convenience for customers. The pre-treatment room for sample testing mainly considers ventilation requirements. The instrument analysis room mainly considers requirements such as electrical load, temperature and humidity control, gas circuit, ground wire, and fire protection measures. The weighing room should consider requirements such as stable airflow, no vibration, and isolation buffering. The standard solution preparation room should consider requirements such as independent space and prevention of cross contamination. Clean areas such as microbiological testing rooms, genetically modified ingredient testing rooms, and food toxicology analysis rooms should meet the requirements of relevant national technical specifications.

In terms of other related facilities, the distribution power of agricultural product testing laboratories should generally have a 10% power surplus for each workspace.

A good ventilation system is the key to ensuring the normal operation of a laboratory. We usually use organic and inorganic exhaust ducts in the construction of agricultural product testing laboratories, and arrange ventilation cabinets made of different materials such as steel, steel wood, PP, etc. according to user needs, as well as imported exhaust hoods for multiple people to independently operate small laboratories.

The construction and operation of agricultural product testing laboratories require not only precise laboratory equipment and high-quality professional laboratory operators, but also reasonable laboratory planning and layout, as well as appropriate environmental conditions.
