Vegetable constant temperature storage is an indispensable facility in the agricultural production process, which can provide a stable temperature and humidity environment, protect vegetables from sudden changes in temperature and humidity, and prolong the shelf life of vegetables. The following is a detailed introduction to the design and construction of the vegetable constant temperature warehouse.
1.Reasonable site selection: The location of the vegetable constant temperature warehouse should consider the surrounding environment, topographical conditions and the distance between the surrounding vegetable planting area and the market. When selecting the site, we should try to choose a place far away from industrial areas, busy road traffic areas and water pollution areas to ensure the environmental quality of the vegetable warehouse.
2.Building structure: The building structure of the vegetable constant temperature storage should be strong and durable, able to withstand natural disasters and loads. Common building structures include steel frame structures, brick-concrete structures, and the setting of seismic facilities. At the same time, in the design process, it is necessary to make reasonable use of natural light, increase the lighting area, and reduce the dependence on artificial lighting.
3.Thermal insulation materials: In order to maintain a stable temperature in the vegetable constant temperature warehouse, good thermal insulation materials should be selected. Common thermal insulation materials include insulating glass, polystyrene board, polyurethane foam, etc., which can reduce heat transfer and reduce energy consumption.
4.Ventilation system: The ventilation system in the vegetable constant temperature warehouse is very important for the preservation of vegetables. The ventilation system should be able to realize the fresh air entering the warehouse, exhausting the dirty air, maintaining the flow of air and avoiding the breeding of germs. Effective ventilation can be achieved by installing ventilation windows, ventilation fans, and airflow directing equipment.
5.Temperature and humidity control: The temperature and humidity control in the vegetable constant temperature warehouse is the key to keeping vegetables fresh. Air conditioning systems, humidifiers, dehumidifiers and other equipment should be installed to achieve precise control of temperature and humidity. At the same time, the corresponding temperature and humidity parameters should be adjusted according to the characteristics and requirements of different vegetables.
6.Sterilization system: In order to prevent the growth of germs and fungi, a sterilization system in the vegetable constant temperature warehouse is indispensable. Ultraviolet sterilizers, air purifiers, ozone generators and other equipment can be used to eliminate germs and odors in the vegetable storehouse.
7.Water supply: Vegetable cultivation requires a large amount of water. A complete water supply system should be established in the vegetable constant temperature warehouse, including wells, pumps, water tanks and other equipment to ensure the irrigation needs of vegetables.
8.Environmental monitoring system: In order to monitor the temperature and humidity, light, carbon dioxide concentration and other parameters in the warehouse in a timely manner, an environmental monitoring system can be installed. In this way, abnormal situations can be found and adjusted in time to ensure the stability of the environment in the warehouse.
The design and construction of the vegetable constant temperature warehouse are related to the quality and yield of vegetables in the whole planting process. Only reasonable design and scientific construction can achieve good planting and preservation effects of vegetables. Through the comprehensive consideration of the above points, it is believed that some suggestions and guidance can be provided for the design and construction of vegetable constant temperature storage.
