Description

Technical Field

[0001] The utility model belongs to the technical field of composting, and more specifically, relates to a simple shed for vacuum sterilization and composting ripening. Background Art

[0002] With the continuous development of agriculture and the improvement of people's awareness of environmental protection, composting, as an effective method for treating organic waste, has received more and more extensive attention. However, in the current field of composting, the method of manual open-air treatment still dominates, and there are many technical problems with this treatment method.

[0003] Firstly, it is difficult to control the composting conditions in an open-air environment. Factors such as temperature, humidity, and ventilation play a crucial role in the composting ripening process. In an open-air environment, these factors are greatly affected by natural conditions and are difficult to maintain stability. For example, in the hot summer, the composting temperature may be too high, resulting in a decrease in the activity of beneficial microorganisms and even death; while in rainy weather, the composting humidity may be too high, affecting the ventilation effect and slowing down the composting ripening speed.

[0004] Secondly, open-air composting is easily contaminated by the outside world. Dust, impurities, and various pathogenic bacteria in the air may enter the compost, affecting the quality of the compost. At the same time, open-air composting is also easily washed by rain, resulting in nutrient loss and even possible environmental pollution. In addition, the ripening time of manual open-air composting is relatively long. Due to the lack of effective control means, the microbial activity in the composting process is difficult to reach the best state, resulting in an extended ripening time and a reduction in the composting efficiency.
