Description
Technical field
The utility model relates to a kind of drying of wood system, and particularly a kind of microwave of new generation steams row's type composite wood drying system.Belong to microwave applications technology and steam field.
Background technology
At present, because the development of microwave technology utilizes microwave that the drying of material is obtained certain development and application.Microwave has the characteristics of Fast Heating and homogeneous heating for the moisture in the material, and has the high characteristics of the efficiency of heating surface, so microwave drying technology is widely used in agricultural product, Chinese medicine, rubber, plastic industry, and is subjected to effect preferably.
Existing microwave dryer mainly is divided into two kinds: the microwave dryer of batch (-type) or continous way, wherein the microwave dryer of continous way mainly adopts conveyer belt to carry out the conveying of material.In order to prevent the leakage of microwave, equipment openings at two ends aspect ratio is less, and the ventilatory function of equipment is relatively poor, thereby, the only suitable lower material of dry water content, though some equipment has been settled blast apparatus, but, because the defective of conveyor type continuous microwave drying equipment self, material still has many problems in the process of drying, (1) air-flow can only pass through from the upper surface of conveyer belt both sides or material, the upper surface of material is by carrying out material cooling and taking away the steam of evaporation, though the material top layer has obtained good drying, and bottom material internal water steam on the conveyer belt, superfluous heat is difficult to carry out in time with air-flow, it is overheated to be easy to generate, and causes material rotten; (2) because the equipment degassing function is poor, and the steam that produces in the dry run runs into the relatively low equipment inwall of temperature, solidifies residual titration easily, causes by a material and cross thermal denaturation, influenced the quality of product; (3) material is carried the influence that is subject to ambient impurities on conveyer belt, simultaneously causes that easily device interior makes moist when handling the high material of water content, causes short circuit, has influenced the service life of product quality and equipment, and has reduced the quality of product; (4) for the bigger material of water content, because equipment is poor to material internal ventilation function cooling capacity, water vapor diffusion speed is slow, has influenced the rate of drying of material, so steam, heat cause the material over-heat inside easily in the material accumulated inside; (5) layer thickness is owing to be subjected to condition restriction such as material properties, water content, so conveyor type microwave dryer production capacity is difficult to improve; (6) can not effectively contact with material owing to gas, so gas effciency is low, simultaneously, because dry materials is to carry out on the conveyer belt that opens wide, so gas recovery difficulty, cause environmental pollution easily.In addition, the time of delivery of material in drying oven can not be controlled effectively; (7) arid cycle of material long, once need 16 hours, and dry later material easy deformation cracking, dry materials gets inhomogeneous.
So be necessary to design these defectives that a new drying of wood system remedies drying of wood system.
