Description
Technical field
The present invention relates to a kind of for grain drying, and the high electric field drying machine of being powered by solar photovoltaic assembly, particularly a kind of solar energy drum-type high electric field drying machine, belongs to solar photoelectric and utilizes field.
Background technology
Dry, be one of important process in work, agricultural production, directly affect the energy consumption etc. of form, quality and the operation process of product.Dry by food material, not only can obtain meeting the product that water content requires, and other character of food are exerted an influence, as fragrance, color, matter structure, shelf life, nutritive value etc.Drying and dehydrating is very important in food processing, is the larger operating unit that consumes energy.In modern industrial or agricultural department, the drying means conventionally adopting has natural drying, utilizes fuel factor (as power frequency, high frequency, infrared ray, microwave) dry of thermal source or the electric current of steam, hot blast, solar energy, vacuum freeze drying, Sonic drying etc.Although these methods have advantage separately, but can bring a series of problem in actual applications: oven drying and conductive drying (claiming again heated air drying) can cause a large amount of thermal loss, and the interior tissue of dried foods material, color, taste and nutritive value etc. are caused to adverse influence.Although freeze drying can prevent the loss of heat and keep the intact tissue of material, the equipment manufacturing cost of this technology is high, and operating cost is high, and drying time is long, be unfavorable for extensive universal with use, and freeze drying meeting changes the local flavor of food.This just needs a kind of brand-new dry technology, and the loss that both can save the energy can keep again the natural characteristics such as color, local flavor of material preferably.
Roller drying tool disposal ability is large, drying cost is low, simple in structure, uniform drying, can use high-temperature hot-air material to be carried out to the advantages such as rapid draing; But exist baking temperature higher, to some materials, can damage local flavor or be the shortcomings such as abnormal color because of overheated.
High electric field drying: there is facilitation high-voltage electrostatic field to the dry run of evaporation of water and material, utilizing high voltage electric field to be dried material is one of focus of current drying.The effect of high voltage electric field shows and not only can improve rate of drying, the saving energy but also the quality of product is not had to harmful effect.What is more important, corona discharge can produce under room temperature, normal pressure, so high electric field drying carries out under normal temperature (low temperature), is applied to heat sensitive material dry especially noticeable.
Roller drying is combined with high electric field drying, design a kind of drum-type high electric field drying machine, have higher dry mass to have again good drying efficiency, and energy-conserving and environment-protective, market prospects had very much.
Summary of the invention
The problem existing based on above drying mode, the present invention has designed solar energy drum-type high electric field drying machine, not only have that high electric field drying does not heat up (under normal temperature, carrying out) and roller drying advantage evenly and rapidly, and required energy consumption is low, adopt solar photovoltaic assembly (15) power supply can meet energy consumption for drying demand.
