Description

Continuous Rice Blanket Bowl Coupled Ecological Seedling Tray Microwave Jet Impact Coupling Dryer

technical field

The utility model belongs to the technical field of drying equipment, in particular to a continuous type rice blanket bowl coupled with an ecological seedling raising tray microwave jet impact coupling dryer.

Background technique

The total amount of crop straw produced in my country is about 1 billion tons every year, and the total output ranks first in the world. At present, the utilization of straw mainly includes energy utilization, feed utilization, raw material utilization, and fertilizer utilization. Excess straw is mainly treated by field burning. Straw burning not only causes waste of resources and environmental pollution, but also destroys the ability of soil to resist drought and keep moisture. Therefore, the utilization of straw resources has become an urgent problem to be solved.

Rice blanket and bowl coupled ecological seedling raising tray (abbreviated as ecological seedling raising tray) is an upgraded product of rice straw nutrition plug tray. It is prepared by drying and other processing techniques. Therefore, the production of rice blankets and bowls coupled with ecological seedling trays not only consumes a large amount of crop straws and increases the resource utilization of straws, but also produces ecological seedling trays that can store water and protect moisture, improve soil fertility, prolong the growth period of rice, and improve rice production. Yield and other advantages, increased farmers' income.

In the production of ecological seedling trays, after vacuum adsorption molding, the ecological seedling trays have high moisture content and low strength, which cannot meet the requirements of sowing, seedling raising, transplanting and transportation. Therefore, the vacuum adsorption forming ecological seedling trays must be dried. to meet production requirements. At present, the drying of ecological seedling trays (rice straw nutrition plug trays) mainly includes natural drying and hot air drying. The natural drying ecological seedling tray is greatly affected by the natural environment, and the drying efficiency is low. The dried ecological seedling tray has low strength and serious warpage, which seriously affects the quality of the ecological seedling tray and the follow-up work of rice production; although hot air drying can meet the requirements of ecological seedling breeding However, hot air drying has low efficiency and high energy consumption, which increases production costs and hinders the further promotion and application of ecological seedling trays. Therefore, a new drying method is urgently needed to dry ecological seedling trays.

Microwave drying technology is one of the hot fields and directions in the current drying technology research. Microwave drying is that microwaves are guided into the interior of the material through the waveguide device, and the interior of the material rapidly absorbs microwave energy to increase the temperature, causing the moisture in the material to migrate from the interior to the surface and evaporate from the surface of the material, and finally achieve the purpose of drying. Compared with traditional drying methods, microwave drying has the characteristics of fast drying speed, high heat transfer efficiency and short drying time; microwave drying also has uniform heating temperature, high drying quality, simple equipment and easy operation and control, high heat energy utilization rate, energy saving and environmental protection. specialty. However, if the heating rate of microwave drying is too fast, the moisture inside the material cannot be discharged in a timely and effective manner, or the internal temperature of the material is too high, causing the surface of the product to harden or gelatinize, thus affecting the drying quality.

Gas jet impingement drying is a drying method in which heated gas with a certain pressure is ejected through a nozzle of a certain shape at a relatively high rate and directly impacts the surface of the material during the drying process, thereby taking away the moisture inside the material. During drying, the gas is ejected through the nozzle as a low-quality fluid and impinges on the surface of the material at a very high speed, resulting in a very thin gas boundary layer on the surface of the material, thus effectively improving the heat and mass transfer efficiency between the drying medium and the surface of the material. Compared with traditional hot air drying, gas jet impingement drying has a heat transfer coefficient several times or even an order of magnitude, which enhances the removal of water, thus greatly shortening the drying time and improving the drying speed. However, preheating is required in the initial stage of gas jet impingement drying, otherwise the drying speed and effect will be affected.

Utility model content

Microwave jet impact coupling drying technology is that microwave and high-speed gas jet simultaneously act on the dry material to dry the dry material. The microwave jet impingement coupled drying technology combines the advantages of microwave drying and gas jet impingement drying, and has a faster drying rate and higher drying quality than microwave drying and gas jet impingement drying.
