Description
Technical field
The invention belongs to drying equipment technical fields, and in particular to a kind of fixed ecological seedling-cultivation plate of rice blanket alms bowl coupling is micro-
Wave jet impulse couples drying machine.
Background technique
The total amount that China generates agricultural crop straw every year is about 1,000,000,000 tons, and total output accounts for first place in the world.Currently, the benefit of stalk
With main including several ways such as recovery energy, fodder utilization, raw material utilization and Fertilizer Transformed cropland applications, but the whole nation is every
Still there are 200,000,000 tons of stalk development and utilization not yet in effect year, superfluous stalk is mainly handled in such a way that field is burned.Stalk
Burning not only causes the wasting of resources and environmental pollution, while also destroying the drought-resistant moisture-preserving ability of soil.Therefore, stalk resource
Change using as current urgent problem to be solved.
It is rice straw nutrition hole tray upgraded product that rice blanket alms bowl, which couples ecological seedling-cultivation plate (referred to as ecological seedling-cultivation plate),
It adds nutritional additive necessary to paddy growth, sterilization agent using agricultural crop straw as primary raw material, through air pressure
The processing technologys such as molding and dryness finalization are prepared.Therefore, rice blanket alms bowl couples ecological seedling-cultivation plate production, and not only consumption is a large amount of
Agricultural crop straw, increase the resource utilization approach of stalk, and ecological seedling-cultivation plate produced also has and retains and conserve soil moisture, mentions
High soil fertility extends rice growing season, improves the advantages that rice yield, increases the income of peasant.
In the production of ecological seedling-cultivation plate, ecological seedling-cultivation plate is after vacuum adsorption molding, and moisture content is high, and intensity is low, can not
Meet the requirement of sowing, seedling, rice transplanting and transport, therefore, it is necessary to the ecological seedling-cultivation plate after vacuum adsorption molding is dried,
To meet production requirement.Currently, ecological seedling-cultivation plate (rice straw nutrition hole tray) drying mainly has natural drying and heated-air drying
Two ways.The ecological seedling-cultivation plate of natural drying is bigger by natural environment influence, and drying efficiency is low, the ecological seedling-cultivation plate after drying
Intensity is low, and warpage is serious, seriously affects the follow-up work of the quality and Rice Production of ecological seedling-cultivation plate；Although heated-air drying can
Meet the requirement of ecological seedling-cultivation plate dry mass, but heated-air drying low efficiency, energy consumption is big, increases production cost, hinders life
Therefore the further promotion and application of state seedling-cultivation plate are badly in need of doing ecological seedling-cultivation plate using a kind of novel drying mode
It is dry.
Microwave drying technology is one of hot fields and direction in current dry technology research.Microwave drying is that microwave is logical
It crosses waveguide assembly to lead into inside material, absorbing microwave energy inside material rapidly rises temperature, causes moisture in material
It is evaporated from inside to surface migration and from surface of material, is finally reached drying purpose.Compared with traditional drying mode, microwave drying
Have the characteristics that rate of drying is fast, heat transfer efficiency is high, drying time is short；Microwave drying be also equipped with heating temperature uniformly, dry product
The characteristics of matter is high, the simple easily operated control of equipment, heat utilization rate height, energy conservation and environmental protection.But the heating that microwave drying is too fast
Rate will lead to that the moisture inside material cannot timely and effectively be discharged or internal batch temperature is excessively high that product surface is caused to harden
Or gelatinization, to influence drying quality.
Gas jet impact drying is in the drying process to pass through the heat gas with certain pressure with higher rate
The nozzle of certain shapes sprays and directly impact is in surface of material, to take away the drying mode of material internal moisture.When dry,
Gas is sprayed as low-quality fluid through nozzle and with high rate impact in surface of material, causes the gas side of surface of material
Interlayer is very thin, to effectively improve the heat and mass transfer efficiency of dried medium and surface of material.With traditional heated-air drying
It compares, the dry heat transfer coefficient having beyond several times or even an order of magnitude of gas jet impact strengthens the exclusion of moisture, because
And drying time is substantially reduced, improve rate of drying.But gas jet impact drying is bigger to the consumption of energy,
It is unfavorable for saving production cost.
Microwave jet impact coupling dry technology is by microwave and high-speed gas jet while to act on dried material, right
Dried material is dried.Microwave jet is impacted coupling dry technology there is presently no scholar to apply on dry materials, more
There is no scholar to apply technique on ecological seedling-cultivation plate is dry, and realizes the drying of microwave jet impact coupling dry technology
Equipment research is at home and abroad or blank out.
