Description
Technical field
The present invention relates to tobacco manufacture field, be specifically related to a kind of tobacco scrap prodn processing method controlling material water ratio.
Background technology
Tobacco scrap prodn process is whole process smoked sheet being processed into cut tobacco, and common processing process is as follows: and loosening and gaining moisture-Ordering and casing-storage leaf-tobacco leaf heats-and chopping-cut tobacco warming and humidifying-cut tobacco drying-ratio mixes and joins-tobacco perfuming.As can be seen from above-mentioned technological process, tobacco scrap prodn processing can be divided into blade sections processed and cut tobacco section two large divisions processed, finally need could form pipe tobacco finished product after the humidification of multiple working procedure, dry etc. processes.
In humidification or the process of drying, material and hot wet gas current carry out Mass and heat transfer, and then affect physical quality and the aesthetic quality of product.As can be seen here, in whole process, the accurate control of material water ratio plays a very important role for the formation of the processing quality of tobacco.
Present stage, in tobacco scrap prodn process, the CCP of material water ratio mainly contains following two:
(1) control of tobacco leaf humidification moisture.Namely smoked sheet is through the process of loosening and gaining moisture operation, carries out warming and humidifying.In above process, mainly through the control of loosening and gaining moisture operation amount of water parameter, requirement is set with tobacco leaf material target moisture content after satisfied moisture regain, meets the processing request of the operations such as follow-up chopping, cut tobacco be dry simultaneously.At present, in the process of same trade mark cigarette product different batches, loosening and gaining moisture operation amount of water pre-set parameter is identical, and does not arrange bound adjusting range.
(2) cut tobacco is dried the control of process moisture.Tobacco leaf is after chopping, and now moisture is higher, again through the process of cut tobacco drying process, need carry out dehydration of drying.In above process, mainly through the control of drying equipment hot blast temperature (air-flow) or barrel temperature (thin plate) parameter, requirement is set with satisfied dry posterior lobe silk materials target moisture content, meets the processing request of finished cut tobacco moisture after dry run aesthetic quality and perfuming simultaneously.At present, in the process of same trade mark cigarette product different batches, the setting value of cut tobacco dry posterior lobe silk materials target moisture content is identical, and does not arrange bound adjusting range.
Current, adopt material water ratio control method in above-mentioned tobacco scrap prodn process, main exist following two deficiencies:
(1) adopt existing control method, same trade mark cigarette product cut tobacco dry entering water rate differences between batches are larger.Be in particular in: when tobacco leaf supplied materials state changes, when such as tobacco leaf supplied materials moisture is higher or on the low side, in loosening and gaining moisture operation, if the now same trade mark, different batches still adopts identical moisture regain amount of water, after then causing moisture regain, target moisture content runaways, in addition, under Various Seasonal varying environment temperature and humidity conditions, material is exported to the cut tobacco dry entrance process material moisture degree of scattering and disappearing from loosening and gaining moisture and differs widely, and then cause product to criticize a cut tobacco dry entrance moisture generation larger difference, affect the stability of cut tobacco drying process key parameter, thus affect same trade mark cigarette product criticize between the level of processing that homogenizes.
(2) adopt existing control method, after perfuming, finished cut tobacco moisture easily occurs exceeding standard control overflow.Be in particular in: when processing environment state changes, when such as ambient temperature and humidity is higher or on the low side, cause material to be exported to tobacco perfuming entrance moisture loss degree from cut tobacco drying to differ widely, if now cut tobacco drying process same trade mark cigarette product different batches still adopts target moisture content design load after identical drying, after then causing perfuming, moisture in cut tobacco runaways, and then it is defective to cause finished cut tobacco moisture to occur, significantly affect physical quality and the aesthetic quality of product.
Summary of the invention
