Abstract
The utility model relates to an automatically transmitting device for a mini drying machine, which is a device designed for enhancing cost performance of the low speed transmission system of an original mini drying machine. The inside of the machine is provided with multiple groups of overlapping transmission bands, an electromechanical integration electromotive machine with small power and speed reducer is adopted, and an original electromotive machine and a mechanical speed reducing device are replaced by the electromechanical integration electromotive machine. The utility model has the advantages of small size, light weight, low cost, less power consumption, high reliability and easy fabrication. In addition, after multiple strips of transmission bands with lower cost is adopted in the machine, the drying amount of the machine is enhanced, and furthermore, the drying degree and the drying evenness are also observably improved.
Description
The utility model is a kind of device that designs for the ratio of performance to price of the small-sized or miniature dryer low speed automatic transmission system that improves agricultural byproducts processing special uses such as traditional food, tealeaves.
The low speed transmission device of miniature dryers such as existing food, tealeaves is owing to adopt off-gauge mechanical reduction gear, and not only cost height, volume are big, the processing more complicated, and also reliability is also relatively poor.In order to overcome above-mentioned shortcoming, the method that adopts the vibration feeding is also arranged, although also can reach the purpose of transmission, transmission speed is difficult for stable.Particularly when requiring transmission speed very low, there are many enchancement factors all will make this parameter of transmission speed become variable, even zero or negative occur.This will directly exert an influence to the oven dry uniformity, and will be unfavorable to improving product specification.And to some agricultural byproducts in whole heating, drying process because to be subjected to stronger impact shock easily broken and produce powder always.
In addition, existing miniature dryer is limit by volume, and the oven dry in oven dry degree and unit interval measures that this is also very outstanding to contradiction, often can not first drying.From the angle of drying, total time length of wishing baking that is to say to make the interior transmitting speed of dryer good a bit slowly, but this is very unfavorable to the oven dry amount.Their relational expression is respectively: oven dry amount=channel width * transmission speed * oven dry thickness
Oven dry degree=(baking temperature)/(oven dry thickness) * drying time=(baking temperature)/(oven dry thickness) * (passage length)/(transmission speed)
Passage in the formula refers to the part that infrared ray can dry by the fire on the transport tape, and oven dry thickness refers to the thickness that baked article is spread on the transport tape.
By following formula as can be known: transmission speed is directly proportional with the oven dry amount, is inversely proportional to the oven dry degree, needs the two to take into account (ordinary priority satisfies the oven dry degree) during design.The baking temperature height is favourable to shortening stoving time a bit, but limit by maximum permissible temperature.The food thickness of being dried is favourable to improving the oven dry amount greatly a bit, but is subjected to the restriction of the oven dry degree and the oven dry uniformity.Channel width can improve the oven dry amount greatly a bit, and the oven dry degree is not had influence yet, but is subjected to the restriction of floor space and cost.Optimal way is exactly the effective length that increases passage under the situation that does not increase the dryer volume.Can increase transmission speed under the prerequisite of drying time and do not influence the oven dry degree satisfying like this, increase the oven dry amount of dryer because of increasing transmission speed simultaneously in the unit interval.But existing miniature dryer is subjected to himself length to limit the increase that its passage length can not be at double.
The purpose of this utility model is to provide a kind of volume little, and cost is low, reliability is high, can improve the automatic conveying device of miniature dryer performance.It reduces energy consumption, reduces cost by the volume that dwindles automatic conveying device, or increases the transport tape group also mutually to fetching the raising drying capacity and improving the oven dry degree under the prerequisite that does not increase former cost.
The utility model is achieved in that with the electromechanical integration motor of small-power band decelerator and replaces original motor and mechanical deceleration device, with reduced volume and weight, reduce cost and energy consumption, increase reliability etc.With many groups of overlapping transport tapes by mutually to fetching the increase passage length, increase the oven dry amount to reach.Reach different baking thickness with the different transmission speed of each group transport tape, adjusted the position and the angle of baked article when between each group, joining mutually simultaneously, with the further improvement oven dry degree and the oven dry uniformity.
The utility model is described in further detail below in conjunction with accompanying drawing.This figure is that example is only done an explanation to its driving section with the tea drier.
Accompanying drawing 1 is the schematic diagram of this automatic conveying device, and wherein b figure is the schematic side view of automatic conveying device.Tealeaves is poured into from material bin (2).Enter transport tape (5) through inlet treating apparatus (1), along with the slow rotation of the axle (6) that slowly runs, tealeaves is brought into transport tape (5) and slowly moves forward, and is subjected to the baking of infrared heater (4) simultaneously.Reflect heat plate (3) is provided with in order to improve the thermal efficiency.By blanking plate washer (7) tealeaves being turned over automatically when tealeaves is walked to be at the end by last transport tape (5) falls down on the transport tape (5), by turning over, has changed the baking position and the angle of tealeaves automatically.The transmission speed of following transport tape (5) makes that greater than last transport tape (5) transport tape (5) is gone up the tealeaves thickness minimizing of toasting down.To improve the baking uniformity of tealeaves.Tealeaves is finished the overall process of oven dry at last from dryer outlet (8) automatic outflow.
Transport tape can be respectively directly driven by the electromechanical integration permagnetic synchronous motor (9) of two small-power band decelerators up and down; Also can connect axle (6) (the seeing schematic side view 2) that slowly run up and down, only use a motor (9) to drive by belt (10).The electrical power of motor (9) is general≤20W.For 3～4 transport tapes can be set in the dryer of higher gears, and also a transport tape can only be set for low-grade dryer.The transmission speed of transport tape can be regulated according to the needed time of drying tea leaves.Because the synchronous motor rotating speed is accurate, mixes the electrical adjustment controller and can regulate more accurately transmission device, can adapt to the higher technological requirement of various precision, this is vital to the class that improves the quality of products.
Be subjected to the temperature rise restriction not allow the food or the agricultural byproducts of high temperature heat radiation for some, thermal convection current and heat conducting effect ratio will rise, and at this moment can set up the gentle breeze machine and impel the heat convection current, so that further quicken drying and improve hot uniformity coefficient.
