Description

A solar energy storage device

technical field

The utility model relates to the technical field of agricultural product processing, in particular to a solar energy storage device.

Background technique

Traditional open solar drying (also known as natural drying) is the most common method of agricultural product processing. During the drying process, materials are laid out in the sun to remove moisture. The method is simple to operate and low in drying cost, but the drying process is easily affected by climate change and external environment, which makes the dried product vulnerable to secondary pollution such as microorganisms, dust, and rainwater.

In addition to traditional open solar drying, drying technologies such as heat pump drying, freeze drying, and infrared drying have also been widely used in industrial-scale food processing. These technologies require large investments and are accompanied by a large amount of fossil fuel consumption and greenhouse gas emissions. Drying, as an energy-intensive and high-greenhouse gas-emitting industrial operation unit, consumes about 7-15% of a country's total industrial energy consumption. Drying produce using renewable energy can play an important role in food security, low carbon footprint and sustainability, as well as curbing climate change. Therefore, solar energy is a dry renewable energy source suitable for agricultural products.

Existing solar drying technologies mainly include direct solar drying and indirect solar drying. Direct solar drying is directly completed by solar radiation; indirect solar drying is equipped with a solar collector and an independent drying chamber, and the heat energy of the collector is transported to the drying chamber under the action of natural convection or forced convection. Since the direct solar drying technology directly utilizes the radiation of sunlight, the solar drying temperature will periodically change with the intensity of solar radiation and the ambient temperature, and an unsuitable drying temperature will have an adverse effect on the quality of the dried product. For example, if the drying temperature is too high, it will lead to serious color deterioration and loss of nutrients of agricultural products, and if the drying temperature is too low for a long time, it will lead to adverse reactions such as fermentation and hydrolysis of high-moisture agricultural products.

However, the existing solar drying equipment has high requirements on the weather. When the light is insufficient, the drying process is difficult to carry out normally, which will lead to a decrease in drying efficiency and a significant extension of the drying process, which in turn will lead to the deterioration of the quality of agricultural materials during the drying process. In addition, when the irradiation intensity is too high, there may even be extremely short-lived high temperatures, which in turn will cause the degradation of nutrients and quality deterioration of agricultural products. It is precisely because of the uneven irradiation of solar energy and the large difference at night that it is difficult for solar drying equipment to work continuously around the clock. How to collect abundant solar energy during the day for use at night or when there is insufficient care, and use the collected energy in conjunction with solar drying equipment , so that the round-the-clock operation of the drying equipment has become an urgent problem to be solved.
