Brief description
Fig. 1 is the structural representation of an embodiment of fragrance retracting device of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this.
As shown in figure 1, the present invention provides a kind of method that use multi-stage condensing device reclaims fragrance, including：One retort is provided
1, carry out Maillard reaction in this retort 1；There is provided multi-stage condensing device 2, multi-stage condensing device 2 is arranged on described retort 1
Top, and multi-stage condensing device is distributed in the horizontal direction, and the bottom of first order condenser from front to back connected by air inlet pipeline 3
To described retort 1, the top of previous stage condenser is connected to the bottom of rear stage condenser, previous stage by the first pipeline 7
The top of condenser is connected to the top of rear stage condenser by the second pipeline 8, and the bottom of every grade of condenser is provided with one
Individual discharging tube 5, is provided with first flow control valve 6 on each first pipeline, is provided with second on each second pipeline
Control valve 9, each discharging tube is connected to described retort；From front to back, the cooling being continually fed in multi-stage condensing device follows
The temperature of ring water is successively decreased step by step, and 3～6 DEG C of the temperature difference of the cooling circulating water in adjacent condensed in two stages device；Treat that Mei Lade is anti-
Should start, open first flow control valve step by step from front to back, and at interval of first time period, open a first flow and control
Valve, opens second flow control valve from front to back step by step, and at interval of first time period, opens a second flow control valve,
Wherein, the first flow control valve between identical two condensers and second flow control valve are opened simultaneously, and this first
The flow of flow control valve is more than the flow of this second flow control valve.
It is introduced into ranking in the most forward first condenser from front to back from gas out in retort, cold by this
Condenser heat exchange, cooling, some the group branches in gas condense, and are flow back in retort by discharging tube；When continuing one section
Between after, open the most forward first flow control valve of ranking and second flow control valve, residual gas passes through first pipe more respectively
Road and the second pipeline enter in rear stage condenser, and gas is cooled down by this condenser, and a part of component condenses again；In the past
Open first flow control valve and second flow control valve step by step backward, thus condensing to gas step by step.The invention enables
Gas is persistently condensed after a period of time (i.e. first time period) in every grade of condenser, then first-stage condenser flowing backward, carries
The high condensation efficiency to condenser, that is, improve the organic efficiency to fragrance component, and reduce energy consumption.
And, previous stage condenser expellant gas simultaneously enter bottom and the top to rear stage condenser, rear stage
The gas entering from bottom in condenser flows up, and the gas entering from top flows downward, and this two strands of gases are interfering with each other,
Thus producing the air-flow of disturbance in rear stage condenser, and then improve the heat exchange effect to gas in it for the rear stage condenser
Really.Because the proportion of gas is larger, therefore from bottom to the gas that flows upward can relative motion slower, and from top to dirty
Dynamic gas can relative motion very fast, when the flow of the flow-rate ratio second flow control valve from first flow control valve is big, that is, from
The gas flow that bottom enters rear stage condenser is bigger than the gas flow from top entrance rear stage condenser, can strengthen two
Stock gas degree interfering with each other, and then improve heat transfer effect.
Preferably, described use multi-stage condensing device reclaims in the method for fragrance, for every grade of condenser, temperature detector
For detecting the temperature of cooled gas in corresponding condenser；For previous stage condenser, the temperature detecting when temperature detector
When angle value is consistent with the temperature of the cooling circulating water in corresponding condenser, then through second time period, then open this previous stage cold
Condenser rear and adjacent with this previous stage condenser first flow control valve；This second time period is passed through with lower section
Formula calculates：Using the Maillard reaction time precomputing divided by condenser number.
Specifically, the cooled gas of the actual inclusion of first time period reaches the temperature of cooling circulating water in this condenser
Time and second time period.I.e. the present invention will ensure that cooled gas just can continue to rear stage after by fully heat exchange
Condenser flows, so that this grade of condenser fully acts on；In addition, after by abundant heat exchange, the component in cooled gas is cold
Coagulate there is still a need for certain time, in order that condensation fully occurs in addition it is also necessary to again through second time period.During Maillard reaction
Between can be determined according to prepared product type and effect.
Because the cooling circulating water in condenser is continually fed into, it is therefore contemplated that with the changing of cooled gas
In thermal process, the temperature of the cooling circulating water in condenser does not raise, and only there occurs the temperature drop of cooled gas.
Preferably, described use multi-stage condensing device reclaims in the method for fragrance, and the cooling in two neighboring condensing tube follows
3 DEG C of the temperature difference of ring water.This temperature can ensure that the component in gas stepwise condense so that last in gas
Fragrance component recovering effect best.
Preferably, described use multi-stage condensing device reclaims in the method for fragrance, and each discharging tube 5 is provided with one the
Three flow control valves 4, when first flow control valve is opened, with above this first flow control valve and this first
The 3rd flow control valve corresponding to the adjacent first-stage condenser of flow control valve is opened simultaneously.When first-stage condenser is started working
When, its 3rd flow control valve is also opened, so that condensed component can be expelled back in retort again.Certainly,
3rd flow control valve can also be set between first-stage condenser and retort, and it is right that the 3rd flow control valve is used for deciding whether
Gas in retort carries out condensation process.
Preferably, described use multi-stage condensing device reclaims in the method for fragrance, and any level condenser condenses for shell and tube
Device.
The number of condenser can select 6 to 10 grades.
Preferably, described use multi-stage condensing device reclaims in the method for fragrance, and the flow of this first flow control valve 6 is
1.2～1.4 times of the flow of this second flow control valve 9.Through calculating, for rear stage condenser, when enter from bottom
When the flow of gas is 1.2～1.4 times of the flow of the gas entering from top, the flow perturbation situation in rear stage condenser
Best suit requirement, heat transfer effect is best.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in description and embodiment
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Realize other modification, therefore under the general concept being limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
