Description
Technical field
The utility model relates to Chinese medicine drying device, specifically refers to resistance heated medicinal material dryer.
Background technology
Traditional Chinese medicinal material drying equipment for drying, adopts wind-heat to dry, and its advantage is to be heated evenly, but its complex structure, need to possess heating part, heat exchange section, air intake part and air-outlet part, its design principle, general adopt boiler heat hot water or utilize factory's used heat to carry out heat exchange, air is heated, air needs to be dried processing in heating as last, then the air dry, temperature is high is passed into medicinal material and holds position, medicinal material is dried.
Design based on prior art and the specific (special) requirements of medicinal material, for most of Chinese medicines, dried quality of medicinal material is light, have for blade, have for coring, have for stem, have for fruit particle, and if these Chinese medicines also adopt the mode of wind-heat to process, can cause the medicinal material in drying chamber to fly upward everywhere, the collision between medicinal material causes a lot of broken ends to produce.Therefore lower for the medicinal material quality of finished after the dry processing of wind-heat.In addition, because wind-heat is dried, equipment is more, complex structure, so production cost and maintenance cost etc. are very high, so the ratio of input ratio output is larger.
Utility model content
The purpose of this utility model be to provide a kind of structure single, can meet medicinal material and dry the medicinal material drier that can not cause medicinal material to fly upward and be heated evenly, i.e. resistance heated medicinal material dryer.
The purpose of this utility model is achieved through the following technical solutions: resistance heated medicinal material dryer, it is characterized in that: comprise housing and run through housing and for carrying the transmission crawler belt of medicinal material, the left side of transmission crawler belt is provided with resistance heater A, the right side of transmission crawler belt is provided with resistance heater B, directly over transmission crawler belt, be provided with resistance heater C, under transmission crawler belt, be provided with resistance heater D; Along the transmission direction of transmission crawler belt, the resistance value of resistance heater A and resistance heater B all increases gradually; Along the transmission direction of transmission crawler belt, the resistance value of resistance heater D and resistance heater C reduces gradually; Resistance heater D is all connected with inner walls by lifting linking member with resistance heater C, directly over transmission crawler belt, is provided with range sensor, and range sensor and lifting linking member are all connected on controller.
The course of work of the present utility model is: medicinal material is placed to transmission crawler belt, under the drive of transmission crawler belt, medicinal material slowly moves ahead, utilize range sensor to detect the thickness of medicinal material, the time tranfer detecting is to controller, by controller judge whether to drive lifting linking member drive resistance heater D or and resistance heater C, make resistance heater D or and resistance heater C apart from the gap of medicinal material, whether change, to adapt to the medicinal material heating of different-thickness, if medicinal material is thinner, flower class for example, the medicinal material of blade class, need resistance heater D or and resistance heater C larger to the distance of medicinal material, in order to avoid medicinal material is subject to heat transition, but for tubers, root class, the medicinal material of fruit class needs stronger heat radiation, therefore need resistance heater D or and resistance heater C less to the distance of medicinal material, according to this demand, the utility model adopts said structure can adapt to the drying and processing of different medicinal material types, be heated and be protected, can there is not the overheated or not foot phenomenon that is heated, in like manner resistance heater A and resistance heater B also can adopt similar structures.
The problem that can cause medicinal material to fly upward everywhere in order to solve wind-heat in addition, the utility model, from changing the thinking of thermal source, adopts resistive heating device as thermal source, utilizes heat radiation to heat, although the drying rate of this mode is comparatively slow, the quality of the medicinal material after finished product is higher.For thermally equivalent, the utility model is provided with resistance heater A in the left side of transmission crawler belt, the right side of transmission crawler belt is provided with resistance heater B, utilize the hot mode that is subject to of both sides, make medicinal material obtain heat treated at left and right sides simultaneously, simultaneously, after entering medicinal material for fear of the initial stage, be heated too fast, cause the outside overdrying of medicinal material and medicinal material inside is excessively wet, therefore, the utility model adopts slowly the mode of heating gradually, makes medicinal material inside and outside be heated and increase progressively, and reaches medicinal material and also can reach dry effect in the inside outside dry time.Find after deliberation, when medicinal material one enters temperature between dry section when higher, medicinal material surface is heated too high, can form wink-dry, so internal moisture drying efficiency can reduce.Therefore, the utility model is in order to address this problem, make along the transmission direction of transmission crawler belt, the resistance value of resistance heater A and resistance heater B all increases gradually, like this, from transmission crawler belt transmission direction, hot-zone between temperature increase gradually, make drying effect faster, better, the mode of this slow heating makes medicinal material moisture content inside and outside all can reach comparatively unified effect.
