Technical field
The present invention relates to a kind of burley tobaccos that improve and bakes method and the device that machine exports moisture content in leaves uniformity.
Background technology
The operation principle that Primary processing shop burley tobaccos bake machine equipment is the white rib cigarette sheet by being machined into 34% moisture, after entering roasting machine, in the process of advancing with roasting machine web plate band, dry by the Hot-blast Heating in roasting machine, and removes ammonia wherein; Then, dry blade is cooled in cooling zone, and is adjusted to the moisture of about 16% by atomization air flow in moisture regain district.
Nozzle that burley tobaccos bake machine moisture regain district has and sprays downwards, also to have and upwards spray, existing burley tobaccos bake the structural representation of machine moisture regain district nozzle as shown in Figure 1, this nozzle is the one of upwards spraying, tobacco leaf conveyer belt is above nozzle, water flows through from water pipe 1, and steam flows through from steam pipe 3, and nozzle 2 is arranged on steam pipe 3 successively; Steam and water are mixed to form steam atomization water in nozzle, are sprayed on tobacco leaf.Because steam and water are in nozzle interior Hybrid Heating, easily generate incrustation scale and plug nozzle, need often to change, cleaning nozzle, affect normal production and processing, reduce production efficiency, add production cost.
Existing nozzle cannot regulate, and roasting machine cannot adjust in the nozzle atomization effect in moisture regain district, makes on same pipeline five nozzle atomization effects inconsistent.According to equipment mounting structure, steam and running water are supplied 5 nozzles often arranged successively by one end, and the steam of certain pressure and running water are changing through the pressure of 5 nozzles successively, and pressure reduces gradually.The change of pressure makes nozzle atomization state change.The moisture content in leaves on roasting machine transporting reticulation belt is finally caused to occur uneven situation.
Before transformation, the moisture content of outlet of single batch is listed as follows shown in table.
Summary of the invention
Object of the present invention is exactly to solve the problem, there is provided a kind of and improve method and the device that burley tobaccos bake machine outlet moisture content in leaves uniformity, solve five nozzles on series pipe because the spray pattern variation issue of fluid medium pressure fluctuation generation, five nozzles being adjusted to atomizing effect consistent, making the uniform moisture on the tobacco leaf through getting damp again district.
To achieve these goals, the present invention adopts following technical scheme:
Improve the method that burley tobaccos bake machine outlet moisture content in leaves uniformity, comprise the following steps:
The first step, estimation roasting machine moisture regain district adds tidal energy power;
Evaluation method is, tobacco leaf is baked in machine dry section and is baked the moisture of dehydration to about the a% of gross mass; Process goal behind moisture regain district is that biodiversity accounts for b ﹪, then tobacco leaf adds (b-a) % through moisture regain district biodiversity accounting, in production process, tobacco leaf flow is mKg/h, then the amount of water in estimation moisture regain district is about: m × (b-a) %.
Second step, estimates the parameter of original installation site nozzle in roasting machine moisture regain district, comprises spray angle and jet length.
Nozzle, no matter above material or below, all requires that the atomized water of nozzle can be applied on tobacco leaf, namely also has requirement to the jet length of nozzle.
The evaluation method of nozzle atomization angle is, nozzle is L1 apart from the vertical range of tobacco leaf transmission mesh steel band, and the horizontal range between two adjacent nozzles is L2, then nozzle atomization angle θ is estimated as
Jet length is estimated as the vertical range L1 of nozzle distance tobacco leaf transmission mesh steel band.
3rd step, utilizes the data obtained in the first step and second step, carries out design selection to nozzle;
Nozzle selection SJ13 double source nozzle, the atomization angle of nozzle can reach the atomization angle obtained in second step; Jet length also can reach in second step the jet length estimated and obtain; Total Water by all nozzles per hour reaches in the first step water yield needed for moisture regain district moisture regain ability estimated and obtain.
Nozzle is by regulating bottom nut, change the annular cross-sectional area of nozzle supplies water pipeline, thus regulate the size of injection flow rate, by regulating each nozzle on same row, make the nozzle atomization state consistency on same row, range of atomized flow covers the tobacco leaf on whole roasting machine expanded metal lath.The nozzle of original same model is when being installed in series, it is inconsistent that fluid medium pressure fluctuation can produce spray pattern, cause atomizing effect inconsistent, so select adjustable nozzle, by regulating respective nozzle, each nozzle can be matched with the pressure medium of each nozzle mounting points, and atomizing effect is consistent, not influenced by fluid medium pressure difference.
Improve the device that burley tobaccos bake machine outlet moisture content in leaves uniformity, comprise water pipe arranged side by side and steam pipe; On water pipe and steam pipe, be crossed with conduit at a certain distance, across conduit on nozzle is installed.Described nozzle is the nozzle that injection flow rate can regulate.
Beneficial effect of the present invention:
Roasting machine is carried out redesign type selecting at the nozzle in moisture regain district, and nozzle used can regulate injection flow rate, can carry out the adjustment of atomizing effect, makes the nozzle atomization effect on same pipeline consistent, improves the stable and uniform that burley tobaccos bake machine outlet moisture content in leaves.The nozzle that the present invention is used, steam and water realize mixing at nozzle place, can not produce incrustation scale, spray nozzle clogging situation would not occur, effectively extend the nozzle cleaning cycle, improve production efficiency of equipment in nozzle interior.
