Specifically, temperature-detecting device includes the first temperature detecting part and second temperature test section.First temperature detecting part For detecting intake air temperature at shell air inlet and sending inlet air temperature value to controller, second temperature is detected for portion's detection Air outlet temperature at housing gas outlet simultaneously sends out temperature value to controller, and controller is according to inlet air temperature value and air outlet temperature The temperature and/or volume of the cooling gas prepared by value control refrigeration system.The present embodiment is by detecting respectively shell air inlet The temperature or volume that enter the cooling gas in cooling housing 21 are controlled with the temperature of housing gas outlet so that this reality Applying the chiller of example can realize automatically controlling the temperature of Nicotiana tabacum L., and can accurately by the temperature control of Nicotiana tabacum L. Within the specific limits.In addition, being directed to different types of Nicotiana tabacum L., can be at not using the Nicotiana tabacum L. processing system of the present embodiment Within the scope of same temperature, therefore the adaptability of the Nicotiana tabacum L. processing system of the present embodiment is wider.

As shown in Fig. 2 in the present embodiment, conveyer device 1 is conveyer belt.And cooling housing 2 part covers conveying dress Put 1.

In the unshowned embodiment of accompanying drawing, cooling housing can also all cover conveyer device.

In order to improve cooling effect, the cooling housing 21 of the present embodiment is provided with least two shell air inlets.

Preferably, at least two shell air inlets are arranged along the material conveying direction of conveyer device 1.So in conveyer device Diverse location on 1 material conveying direction has cooling gas to enter in cooling housing 2 so that on conveyer device 1 The Nicotiana tabacum L. of diverse location can sufficiently be contacted with cooling gas, realize uniform cooling.

In the present embodiment, cool down housing 21 and be provided with least two shell air inlets.Chiller 2 also includes shunting knot Structure 23.Refrigeration system 22 is connected by flow dividing structure 23 with cooling housing 21.Flow dividing structure 23 include shunting air inlet and At least two shunting gas outlets, shunting air inlet is connected with refrigeration gas outlet, and at least two shunt gas outlets and at least two shells Body air inlet corresponds connection.The setting of flow dividing structure 22 allows the chiller of the present embodiment to realize from least two shells Body air inlet is simultaneously to cooling space input cooling gas so that the cigarette of the diverse location of the load-bearing surface in conveyer device 1 Leaf can carry out contact heat-exchanging with cooling gas and realize cooling simultaneously.

Specifically, flow dividing structure 23 includes the sub- flow dividing structure that at least two-stage is sequentially connected with.As shown in Fig. 2 in this enforcement In example, flow dividing structure 23 includes the sub- flow dividing structure of two-stage.The sub- flow dividing structure of the first order leads to the refrigeration gas outlet of refrigeration system 22 Cross centrifugal blower 30 to connect.In fig. 2, it is schematically shown the first order sub- flow dividing structure has three first shunting outlets Mouthful.Each first shunting gas outlet be connected with the sub- flow dividing structure in the second level respectively again, and such as 2 schematically show second level divides Flow structure has two second shunting gas outlets.Second shunting gas outlet is connected by blast pipe 29 with shell air inlet.

Preferably, it is provided with air adjusting valve 28 between the sub- flow dividing structure of the first order and the second sub- flow dividing structure.Actually used During, can as needed adjust the aperture of air adjusting valve 28 to control to flow to second level son point from the sub- flow dividing structure of the first order The volume of the cooling gas of flow structure.

In order to the concentration for realizing cooling gas is sprayed, blowing to improve cooling effect to the Nicotiana tabacum L. in heaped-up is increased, The chiller 2 of the present embodiment also includes the air nozzle 24 being arranged in cooling housing 21.Below by the concrete of air nozzle 24 Structure is described in detail.

As shown in figure 3, air nozzle 24 includes air nozzle housing 241.There is gas flowing lumen in air nozzle housing 241.Spray Valve housing 241 is provided with the jet air inlet 241A and jet gas outlet 241B for connecting with gas flowing lumen respectively.Jet is entered QI KOU 241A is connected with shell air inlet, and jet gas outlet 241B is connected with cooling space.Cooling gas are from jet air inlet 241A is entered after gas flowing lumen, is sprayed from the 241B of jet gas outlet through the extruding of gas flowing lumen, cooling gas spray The instantaneous velocity for going out is larger, and the Nicotiana tabacum L. to being piled up on the load-bearing surface of conveyer device 1 produces certain impulsive force, can be preferably Nicotiana tabacum L. is blown, cooling effect is improved.

Preferably, jet gas outlet 241B is bar shaped gas outlet, more conducively concentrates injection.

Preferably, jet gas outlet 241B is spaced on the top of the load-bearing surface of conveyer device 1 and along load-bearing surface Horizontal direction extend, horizontal direction is substantially vertical with the conveying direction of conveyer device 1.As shown in figure 3, jet gas outlet 241B Horizontal direction along load-bearing surface extends, and the Nicotiana tabacum L. of the different lateral attitudes on the load-bearing surface of conveyer device 1 is carried out Blow and cool down.And as shown in Fig. 2 it is provided with least two air nozzles on the material conveying direction of conveyer device 1.Therefore originally The chiller 2 of embodiment can be realized blowing comprehensively to the Nicotiana tabacum L. of the diverse location on conveyer device 1, reach uniform cooling Purpose.

As shown in figure 3, Nicotiana tabacum L. T is in heaped-up, it is low middle high that it piles up section both sides.It is thus in the Nicotiana tabacum L. of centre more Many, needing the cooling gas of more high wind speed could seethe all blowing in middle Nicotiana tabacum L..In the present embodiment, jet is entered QI KOU 241A is located at the middle part of the horizontal direction along conveyer device 1 of air nozzle housing 241.So enter from jet air inlet 241A The cooling gas for entering gas flowing lumen can directly from the middle air-out of jet gas outlet 241B, therefore jet gas outlet 241B Middle wind speed is higher, so that the Nicotiana tabacum L. of centre is uniformly hiked up and seethed, reaches preferable cooling effect.

In the unshowned embodiment of other accompanying drawings, multiple air nozzle air inlets, example can also be set on air nozzle housing Such as respectively it is provided with air nozzle air inlet in the both sides and centre of the top of air nozzle housing.Now in order to improve jet gas outlet Middle part wind speed, the circulation area in middle air nozzle air inlet can be made bigger.

In order to adjust the outgassing direction of jet gas outlet 241B, the chiller 2 of the present embodiment also includes angular adjustment machine Structure 25.For different types of Nicotiana tabacum L. or the Nicotiana tabacum L. in different temperatures, can pass through to adjust going out for jet gas outlet 241B Gas direction is adjusting effect of the cooling gas to Nicotiana tabacum L..

In the present embodiment, angle adjusting mechanism 25 is by adjusting conveying of the air nozzle housing 241 relative to conveyer device 1 The angle in direction is adjusting the outgassing direction of jet gas outlet.

In the unshowned embodiment of other accompanying drawings, can also be by adjusting jet air inlet relative to jet gas outlet Position is adjusting the outgassing direction of jet gas outlet.
