Problems solved by technology

In recent years, solar drying has become an important research direction in the field of drying technology at home and abroad. The traditional solar natural drying of agricultural and grain products is a relatively slow process, which is easily affected by climatic conditions such as rainy seasons and showers, and may cause large quality problems. Loss and external pollution, in contrast, solar drying has fast drying speed, good quality of dried products, and will not destroy the nutritional value of its products, and the color is beautiful. It is an effective, cheap and safe drying method for agricultural and food products. However, Solar drying is easily affected by the intermittency and instability of solar radiation, and can only be operated within the sunshine time, which cannot guarantee the continuity of the drying process, resulting in economic losses due to reduced production, moisture resurgence of dried products, and even mildew.
[0003] However, in response to this problem, the current main technical solution is to use conventional energy auxiliary equipment and add low-cost heat storage materials, but there are still problems such as high investment costs and unsatisfactory effects. Therefore, it is important to seek new technical solutions. Practical significance, how to provide a solar drying system based on solid adsorption dehumidification is a problem that those skilled in the art need to solve urgently

Abstract

The invention discloses a solar drying system based on solid adsorption dehumidification. The solar drying system comprises a box body, a solar heat collector and a photovoltaic power supply device; a partition plate is horizontally and fixedly arranged in the box body; the partition plate divides the box body into an adsorption dehumidification chamber and a material drying chamber which are arranged up and down; a plurality of activated carbon fiber columns are arranged in the adsorption dehumidification chamber; and a first air outlet is formed in the top of the adsorption dehumidification chamber and communicates with the outside through a first fan; and a material tray is arranged in the material drying chamber, and an air inlet of the material drying chamber communicates with the solar heat collector; and the photovoltaic power supply device supplies power to the fan. According to the solar drying system based on solid adsorption dehumidification, different operation modes can be adopted according to weather conditions, the problem that solar drying is affected by intermittent and unstable irradiation is effectively solved, stable operation of the agricultural grain product drying process under different weather conditions is achieved, the adopted energy is clean and pollution-free solar energy, and meanwhile loss and waste of electric energy are reduced.

Description

technical field [0001] The invention relates to the technical field of solar drying, in particular to a solar drying system based on solid adsorption dehumidification. Background technique [0002] Drying is an important means of grain processing and value-added, and it is also a major energy-consuming link in the field of storage and transportation. The problem of drying wet grain after harvest has become increasingly prominent. Research on efficient, energy-saving, and environmentally friendly drying technologies has become a hot spot. Solar energy is an environmentally friendly, unlimited, economical, and achievable renewable energy source with great potential for many low-temperature applications, including drying of agro-food products. In recent years, solar drying has become an important research direction in the field of drying technology at home and abroad. The traditional solar natural drying of agricultural and food products is a relatively slow process, which is e...
