Description
Technical field
The present invention relates to a kind of device for the warm adsorption/desorption that grades for biomass water, specifically one kind is applied adds in tobacco
Work field detection lug cigarette or pipe tobacco（Biomass）The device of reclaimed water point isothermal adsorption and desorption process.
Background technology
The porous media that piece cigarette or pipe tobacco are made up of complicated organic substance, can in the heat and wet treatment of tobacco processing course
Some changes can be produced to tobacco leaf or pipe tobacco pore structure, at the same the addition of the outside feed liquid of some in process change tobacco leaf or
Pipe tobacco Surface Physical Chemistry property, causes after processing that moisture absorbs moisture under certain temperature and humidity conditions in piece cigarette or tobacco sample
Certain change is produced with the ability of removing moisture.Piece cigarette or tobacco sample are to the isothermal adsorption of moisture and de- after evaluation processing
When attached ability and changing rule, it will usually including multiple continuous Mass and heat transfer processes, only by entering Mobile state to the process
On-line checking, could carry out effective detection and evaluation to sample water adsorption and desorption ability.Piece is understood by this evaluation
Cigarette or pipe tobacco dry to water adsorption and desorption performance, the physics humectation effect for adding humectant, optimal storage requirement and high temperature
Roasting and moisture regain performance etc..
The migration such as to adsorb and be desorbed under certain temperature and humidity conditions existing for moisture in the biomass such as piece cigarette or pipe tobacco
As.Majority detection method is that different temperature and humidity conditions are set in climatic chamber at present, carries out the detection of process, by offline
Weigh and obtain the data of change in process, and existing commercial on-line checking product is below 30mg moisture to sample bearing capacity majority
The detection of migration, temperature controlling range is more than normal temperature（Normal temperature can not be less than）Or can not complete wet using same complete equipment
Spend continuously adjustable experiment detection work.In addition, the adjustment control response time of existing detection means humidity and temperature is long, surely
It is qualitative to be difficult to meet requirement of experiment.Because moisture transition process is a continuous process in piece cigarette or pipe tobacco, so needing to combine
Online with the advantage of offline two methods, the device for the warm adsorption/desorption that grades for piece cigarette or pipe tobacco reclaimed water is developed.
Inventor once applied for the patent of invention of a Patent No. 201210267723.9, and its is entitled《For

The adjustment control response time of temperature is shorter.But the device has the following disadvantages in test application：1）Because balance is in
The reason in incubator, so calorstat temperature should be arranged on 5 DEG C -50 DEG C（This temperature range is the normal condition of balance, day
Put down when near or above 50 DEG C, be also easy to produce temperature drift or damage）, it is difficult to realize adsorption/desorption of the test higher than more than 50 DEG C
Experiment（Need to be operated and tested in the range of 50 DEG C~90 DEG C to most in the baking of piece cigarette and the performance test that gets damp again, be higher than
50 DEG C have application value）；2）Because saturated moist air is directly produced by water-bath, it is de- that saturated moist air temperature is slightly below absorption
Temperature in alcove, relative humidity under room temperature condition higher than 90%RH is extremely difficult to, and the quick adjustment tested to high humility is made
Into difficulty；3）The temperature of saturated moist air is due to above-mentioned 2）Middle reason, is easily condensed under conditions of high humidity, influence test effect
Fruit and measuring accuracy, meanwhile, damage balance.
