Construction of drying vegetable greenhouse
Before building a drying shed, precise site selection is the crucial first step. It is necessary to choose a high and open flat site, as such terrain is conducive to drainage and flood prevention, effectively avoiding the adverse effects of water accumulation on the shed and the items being dried. At the same time, it is essential to ensure that the surrounding area has convenient transportation for the easy transportation of items to be dried and the finished products, and vegetable greenhouse should also be an adequate and stable water supply as well as convenient access to electricity to meet the daily operational needs.
The design and planning stage of the vegetable greenhouse is of vital importance. Based on the actual drying scale and operation process, the appropriate area and reasonable layout of the vegetable greenhouse should be determined. It is recommended that the vegetable greenhouse be oriented in a north-south direction, as this orientation can maximize the utilization of natural light and ensure uniform lighting inside the greenhouse. The height of the greenhouse should be moderate, ensuring good ventilation while also facilitating the operation and management by personnel inside.
Infrastructure construction is the stable foundation of the vegetable greenhouse. Based on the selected frame material and local geological conditions, the form and size of the foundation should be scientifically designed. Generally, independent or strip foundations can be constructed by pouring concrete, and it is essential to ensure that the depth and strength of the foundation meet the requirements, so as to effectively bear the weight of the greenhouse and external loads.
In the main structure assembly stage, operations must be carried out strictly in accordance with the design drawings. Precisely install the framework to ensure that its verticality and levelness meet the standards, and that all connection parts are firmly and reliably fixed. This can be achieved through welding or bolt connection methods. After the framework is assembled, carefully lay the covering materials to ensure a tight and undamaged coverage, and properly seal the edge parts to prevent air leakage and water leakage.
The installation of ventilation and cooling facilities plays a crucial role in regulating the internal environment of the greenhouse. Ventilation openings can be reasonably set on the top or sides of the greenhouse. The area of the openings should be determined based on the size of the vegetable greenhouse and local climatic conditions. At the same time, manual or electric ventilation equipment such as exhaust fans can be installed to promptly discharge hot air and lower the temperature inside the vegetable greenhouse during hot weather.
After the construction is completed, a comprehensive inspection and debugging of the vegetable greenhouse are necessary. Check whether the connections of all parts are firm, whether the covering materials are damaged, and whether the ventilation, drainage and other facilities are operating normally. Through actual tests, ensure that all performance indicators of the vegetable greenhouse meet the design requirements, and provide a safe, stable and efficient place for subsequent drying operations.
