Description
Technical field
The invention belongs to tobacco drying apparatus control system, specifically one kind being capable of real-time monitoring microwave fixed bed hot blast connection
Close the control system and its method of tobacco dry tenacity in drying process.
Background technology
Microwave fixed bed hot air combined drying equipment can take into account the advantage of microwave drying and fixed bed heated-air drying simultaneously,
Processed material discharge position can be changed, the uniformity of microwave is improved, effective control to microwave can be achieved, accelerate rate of drying, compared with
The flavor components such as the good original color, smell and taste of reservation dried material, obtain desciccate best in quality.
However, existing microwave fixed bed hot air combined drying equipment, data are obtained merely by experiment or experience
Drying process to material is controlled, although can obtain quality of material in drying process in real time, equipment body barrel temperature
And the parameter such as hot blast temperature, but be necessarily required to operating personnel and its Parameters variation is monitored, it will certainly so increase behaviour
Make brought error, increase labour cost, reduce operating efficiency.
Recent study finds the drying tobacco material later stage, is dried using segmented, lowers and dries processing intensity, compared to
Traditional converted products by the way of fixed manufacturing parameter can significantly improve cigarette product organoleptic quality.But existing segmentation
Drying process is sequential control method, i.e., the processing of different drying conditions is carried out in the different drying time section of material.This when
Sequence controlling method, the change of degree of dehydration during dry materials is not considered, i.e., in different drying stages to dry materials condition
Regulation and control only only in accordance with drying time, change and non-correlation with material dewatering state itself.It is different to initial aqueous rate
Identical material, the temporal regulation method is difficult to the purpose for reaching uniformity processing.Simultaneously for the different thing of dehydration complexity
Material, the regulation and control method lacks universality.Therefore, existing regulation and control method it cannot be guaranteed that tobacco processing enterprise to obtain quality on a large scale steady
Fixed cigarette product.
Based on this, it is necessary to invent a kind of control system using Computer Control Technology, the control system can be according to drying
During material dewatering state change, hot air combined to microwave fixed bed dry tenacity carries out automatic on-line control.Computer
The characteristics of with programmable control operation, machined parameters, material just can lower behaviour significantly with one-touch ground output once setting
Make personnel labor intensity, improve operating efficiency.Meanwhile, using the accurate reliable advantage of computer control system, it can strengthen
To the controllability of dry materials process, the quality of dry products is more stablized, be conducive to microwave to fix hot air combined drying and set
Standby further genralrlization popularization.
The content of the invention
One kind that the purpose of the present invention is exactly specially designed for existing microwave fixed bed heated-air drying equipment is applicable
In the dry materials intensity automatic regulating system of the hot air combined drying process of microwave fixed bed, the system can be according to dry materials
During moisture than change carry out the power of each drying unit in control device, the final more stable joint of quality that obtains is done
Dry product.
The purpose of the present invention is achieved through the following technical solutions：
A kind of tobacco dry tenacity automatic regulating system suitable for the hot air combined drying process of microwave fixed bed, including it is dry
Dry equipment body and automatic turnover that is associated with the drying equipment main body and its course of work and condition being controlled
