Technical field
The present invention relates to study the test unit of tobacco (or living beings of similar tobacco) processing characteristics, specifically is the pressurization drying process device that grows tobacco, and this device is used in investigates pressurized conditions to Tobacco drying influence research under the convective drying condition.
Background technology
In the process of tobacco, drying is the important manufacturing procedure that influences tobacco organoleptic properties and physics, chemical property.Many researchs about the tobacco drying have related to the factors such as selection of atmosphere temperature, humidity, flow velocity and drying mode basically; But environmental pressure also is a key factor that influences product quality in dry run; And seldom consider pressure factor in the Tobacco drying process at present; From expanding the angle of dry process of tobacco and research and development, the dry influence that produces has important exploration meaning to tobacco to investigate pressure.In the process of research; Utilize existing dryer change pressure to study and have certain limitation; For example; The existing required test specimen amount of tobacco shreds drying equipment is big, influence normal process of manufacture, the material waste is more, and test condition is limited in scope, and the existing equipment transformation is realized that the pressurized conditions difficulty is bigger.In view of the importance of research contents, the test unit of special is a problem to be solved by this invention.
Investigate the influence research of pressurized conditions to dry materials; Common way be with dried material be placed in advance can the dryness storehouse of bearing certain pressure in; Dryness storehouse is charged into dry gas to boost; When the pressure in the storehouse to be dried reaches to specified pressure, regulate the convective flow that the terminal valve aperture realizes drying medium again.This research method can satisfy the research requirement of the drying of some materials, but for the operating process of tobacco (or similar living beings) practical study, inevitably can introduce some systematic errors, thereby bring certain influence to result of study.For example, fill certain stabilization time that pressure release needs, gas flow temperature, moisture stable also need the regular hour, in stabilization process, can produce considerable influence to material, thereby can't accurately estimate the influence of pressure to dry run.By contrast, a kind of more satisfactory method is under the condition of stablizing the various test parameterss of dryness storehouse, feeds material fast and carries out dried, and can under the condition of not pressure release of dryness storehouse, take out material and carry out next step analysis.
Summary of the invention
The object of the invention just is being based on above-mentioned existing in prior technology problem and the custom-designed one pressurization drying process device that grows tobacco; This device can carry out the experimental study aspect dry under certain pressure, temperature, humidity and wind friction velocity; Obtain tobacco moisture situation and preparation sample over time, be used for analyzing the situation of change of index convective drying processes under the pressurization situation such as physics, chemistry and aesthetic quality of tobacco.
The object of the invention can be realized through following technical scheme: tobacco pressurization drying process device of the present invention; Comprise stress reaction storehouse and feeding warehouse; Connect through spherical valve between stress reaction storehouse and the feeding warehouse; Be provided with inlet gas distribution grid and exit gas distribution grid in the stress reaction storehouse; On the stress reaction storehouse, be connected with the gas pretreatment system of forming by air compressor, air flowmeter, steam generator, steam-flow meter, air heater, in the stress reaction storehouse, also assign the temperature and the temperature thermocouple and the tensimeter of pressure that are useful on the monitoring conversion zone; Be provided with the magnetic force feed arrangement in the feeding warehouse, this magnetic force feed arrangement is by the magnetic force bar that has sample cell and be positioned at the outside magnet of feeding warehouse and form, and feeding warehouse passes through gas admittance valve and is connected with nitrogen cylinder, and on feeding warehouse, is provided with tensimeter.
Air inlet pipeline is provided with the gas flow of safety valve with control system in the stress reaction storehouse, and outlet pipe is provided with and presses valve fully in the stress reaction storehouse, is used to control the storehouse internal pressure.
Inlet gas distribution grid and exit gas distribution grid are horizontal upper-lower position and are placed in the stress reaction storehouse; Conversion zone between two plates (i.e. zone between two gas distribution grids) height is greater than the nominal diameter that connects spherical valve; The two central lines can make sample cell pass in and out reaction warehouse smoothly.
Between feeding warehouse and stress reaction storehouse, be connected with air delivering pipeline, be used for the pressure between balance two storehouses.
The follower arm end connects sample cell, and sample cell is detachable, and handle through punching the bottom, is convenient to air-flow and circulates up and down.
Outside the air delivering pipeline of whole device, be covered with heat-insulation layer, prevent that the atmosphere moisture that causes changes because temperature descends.
Groundwork process of the present invention is following:
At first open the air compressor and the air heat decorum, the over dry air is heated, the preheating reaction warehouse.Open steam generator then, produce the gas of certain humidity, regulate air heating system, the dry gas of certain humidity is heated to the testing requirements value through the quality of regulation flow.According to testing requirements, regulate reduction valve and place certain aperture, the flow velocity of gas in the stopping reaction storehouse; Regulate simultaneously and be equipped with pressure valve; Make the pressure in the reaction warehouse reach the testing requirements value, whether the inspection exhausr port is unobstructed, and whether the valve of coupled reaction storehouse and feeding warehouse is closed.After the sample of known quality put into sample cell, close feeding warehouse, feeding warehouse is charged into inert nitrogen gas; When treating that the feeding warehouse internal pressure equates with the reaction warehouse internal pressure; Open the connection valve, utilize the magnetic force feed arrangement that sample is sent in the reaction warehouse, and pick up counting and image data.After the predetermined processing time, sample to be taken out, the adjustment parameter is tested or by aforementioned opposite orderly close-down system again.
The present invention is a kind of device that can solve the quick down turnover material of pressurization airtight condition; Ultimate principle is to utilize a cold conditions pressure feeding warehouse to be connected with hot pressure drying storehouse, utilizes valve body and magnetic force pay-off to realize the tobacco turnover dryness storehouse under the seal-off pressure condition.This device can be used for the dry dynamic test research of tobacco (or similar living beings), also can be used for the influence research of pressurized conditions to tobacco (or similar living beings) drying quality (physics, chemical property).For dry dynamics research, the influence that test unit of the present invention has avoided stable drying test parametric procedure to bring.
The present invention has following advantage:
1. guaranteeing that reaction warehouse reaches under the situation of reaction conditions; Realized quick feeding in the airtight pressurization space; Avoided between batch test because open, time that closed reaction storehouse and conditioned reaction condition are spent, reduced systematic error.
2. the monitoring of test parameters and easy to adjust and can contain the operating mode of actual production process, and can be used in the dried of tobacco under the condition of normal pressure.
