Embodiment 1

[0023] The hollow fiber membrane in this embodiment can be a high-molecular polymer membrane, which has a hydrophilic gene, and there are many types of high-molecular polymer membranes, so the types are not limited, and the purpose of the invention can be achieved.

[0024] The structure of this embodiment is as figure 1 As shown, the letter in the figure indicates the pipeline number. A drying equipment for agricultural products, including a dehumidification system, a heating system and a drying system. A hollow fiber membrane 2 and a second hollow fiber membrane 4 are connected in parallel. The two hollow fiber membranes are connected by a vacuum pump 3. One end of the vacuum pump 3 is connected to the outlet of the permeable layer of the second hollow fiber membrane 4, and the other end is connected to the first hollow fiber membrane. The inlet of the permeation layer of the membrane 2 is connected, and the water vapor on the permeation layer side of the second hollow fiber...

Abstract

The invention relates to drying equipment for agricultural products and a drying control method, and belongs to the technical field of agricultural machines. The drying equipment structurally comprises a dehumidification system, a heating system and a drying system, and all the systems are connected through pipelines to form loops. The dehumidification system comprises a dehumidification film assembly, the heating system comprises a compressor, a condenser for heating a drying medium, an expansion valve, an evaporator for cooling and dehumidification and a humidification device, and the drying system comprises a drying box. A monitoring device electrically connected with a main machine is arranged in the drying box, and each loop is provided with a three-way valve and a temperature and humidity sensor which are electrically connected with the main machine. The drying equipment for agricultural products and the drying control method have the advantages that air is dehumidified through the low-energy-consumption and high-efficiency dehumidification performance of a dehumidification film, a heat pump is used for auxiliary heating, and the purposes of improving the drying efficiency of the drying system and reducing energy consumption are achieved.

Description

technical field [0001] The invention relates to a drying equipment for agricultural products and a drying control method, belonging to the technical field of agricultural machinery. Background technique [0002] my country is a big agricultural country and a big country in the production, consumption and export of agricultural products. Based on the characteristics of high moisture content, strong seasonality, and concentrated production of agricultural products, it is particularly important to do a good job in post-harvest processing of agricultural products and reduce losses. Drying is an indispensable and important link in the post-harvest processing of agricultural products. It is an important means to remove excess water in agricultural products and retain their nutrients, making them easy to store and transport. At present, the energy consumption of the drying link remains high in the global processing link. Similarly, drying is also one of the most energy-consuming a...
