Description
Technical field
The invention belongs to Tea Production equipment technical field, more particularly to a kind of wild black tea dust pelletizing system and dedusting side
Method.
Background technology
Black tea category full fermentation tea, in black tea rich in carrotene, vitamin A, calcium, phosphorus, magnesium, potassium, caffeine, isoleucine,
The various nutrient elements such as leucine, lysine, glutamic acid, alanine, asparatate, it is the drink that people like, at present, state
The interior main place of production of black tea is distributed mainly on:Sunshine, Anhui Qimen, Guangxi Zhaoping, Yunnan Fo Hai, ShaoXing,ZheJiang, Sichuan Yibin etc.
Ground, contain substantial amounts of dust in the wild black tea newly plucked, it is necessary to by by withering, dedusting, knead, ferment, drying
Drinkable black tea leaf could be made after some row process, at present, domestic tealeaves class enterprise removes to black tea
The general mode using individual event, unit processing during dirt processing, many tealeaves class enterprises are still in the processing using straight-line
Mode, during using this processing mode, due to tealeaves lighter in weight itself, unit dust removal process is not in totally enclosed environment
Lower progress so that dust therein is easily kicked up, and causes the secondary pollution to environment, and the dust partly kicked up returns to tealeaves life again
In other processes during tea, make the dust removal process to black tea leaf not thorough, have impact on the hygienic quality of Tea Production
Product quality, for example, the patent document of Publication No. " CN205040577U ", discloses a kind of black tea process equipment, including such as

Side, buncher B32 output shaft are provided with disc cam 37, and the working face of cam 37 contacts with oscillating plate 31.Black tea is sent
After entering bag filter, collided first with oscillating plate, cause the transporting velocity of the black tea containing dust to reduce, thicker dust exists
Fallen into collision in dust hopper, tiny dust and black tea together enter in dust settling pocket, because power set drive vibrating device
Make vibration intermittently vertically, the black tea containing fine dusts constantly collides with dust settling pocket inwall, makes fine dusts
Absorption is fallen into dust hopper in dust settling pocket in the presence of the intermittent vibration of dust settling pocket, finally, the black tea after filtering
Sent out by discharging opening C, in course of conveying, dust settling pocket constantly vibrates one side black tea, adds between dust and dust settling pocket
Collision probability, improve the efficiency of dust collection of black tea, on the other hand, vibrate and remain cleaning using dust settling pocket, extend pocket type
The service life of filter.
The working face of cam 37 is provided with least one flange.The quantity of flange determines the vibration frequency of vibrating device,
And the height of flange determines the Oscillation Amplitude of vibrating device, preferably Oscillation Amplitude is advisable for 60-240mm, and vibration frequency is
120-180 times/min is advisable.
In addition, present invention also offers a kind of wild black tea dust removal method, comprise the following steps:
Step 1:Wild black tea is sent into settler 1 using conveying device, controls wild black tea in settler 1
Transporting velocity is 35-45m/s, is exported by settler 1 and obtains coarse filtration black tea;The main function of settler is using attached on black tea
The dust the gravity of itself makes relatively large dust natural subsidence fall into collection in dust hopper A, therefore, wild in settler 1
The transporting velocity of black tea is unsuitable too fast, and in order to make bulk dust fully settle, further, dust-catching board 17 is preferably fine using carbon
Particle board manufacture is tieed up, to improve adsorbing powder dust ability.
Step 2:Step 1 coarse filtration black tea is sent into cyclone separator 2, control coarse filtration black tea is in cyclone separator 2
Transporting velocity is 40-60m/s, is exported by cyclone separator 2 and obtains half refined filtration black tea;The main function of cyclone separator 2 be by
Medium sized dust granules are in course of conveying is rotated in coarse filtration black tea, make dust granules throw away under the influence of centrifugal force from
And be attached on the inwall of cyclone separator 2, and finally fall into disposal box B, it is convenient to clean, it also avoid oxygen airborne dust, avoids
Secondary pollution is caused to environment, when it is 40-60m/s to control transporting velocity of the coarse filtration black tea in cyclone separator 2, enters one
Step ground, when preferably to control transporting velocity of the coarse filtration black tea in cyclone separator 2 be 50m/s, can be effectively ensured dust in foot
It is thrown out of under enough centrifugal actions, and can ensures that the collision probability between dust and auger is enough, makes part dust more
Come off in secondary collision.
Step 3:Half refined filtration black tea of step 2 is sent into bag filter 3, half refined filtration black tea of control is in bag type filtering
Transporting velocity in device 3 is 30-40m/s, is collected from the outlet of bag filter 3 and obtains refined filtration black tea;Black tea is sent into pocket type mistake
After filter, collided first with oscillating plate, cause the transporting velocity of the black tea containing dust to reduce, thicker dust falls in an impact
Enter in dust hopper, tiny dust and black tea together enter in dust settling pocket, because power set driving vibrating device makees intermittence
The vibration of ground vertically, the black tea containing fine dusts constantly collide with dust settling pocket inwall, make fine dusts absorption except
In dirt bag, and fallen into the presence of the intermittent vibration of dust settling pocket in dust hopper, finally, the black tea after filtering is by discharging
Mouth C is sent out, and in course of conveying, dust settling pocket constantly vibrates one side black tea, adds the collider between dust and dust settling pocket
Rate, the efficiency of dust collection of black tea is improved, on the other hand, vibrate and remain cleaning using dust settling pocket, extend bag filter
Service life.
Conveying device is ribbon conveyer in step 1.Further, ribbon conveyer is that conveying inclination angle is 30 ° to 60 °
Ribbon conveyer.
Coarse filtration black tea is sent into cyclone separator 2 in step 2, in addition to it is 40 DEG C to control temperature in cyclone separator 2
To 60 DEG C.When to control in cyclone separator 2 temperature be 40 DEG C to 60 DEG C, it can further make the obstinate dust for being attached to black tea surface
Adhesive force reduce so that dust is easier to come off, and half refined filtration black tea is more dried, but temperature is no more than 60 DEG C,
Otherwise can burn black tea surface, the various mineral compositions contained be damaged in black tea, further, it is preferable to control cyclone separator
When temperature is 45 DEG C in 2, the black tea obtained is the purest, and influences minimum to the mouthfeel of drinking of black tea, protects in tealeaves
Nutritional ingredient.
Half refined filtration black tea is sent into bag filter 3 in step 3, in addition to makes half refined filtration black tea in bag filter 3
In vertically vibrate, vibration frequency is 120-180 times/min.In vibration processes, deduster is on the one hand set to be easy to clean,
The service life of bag filter is extended, on the other hand, the collision for adding half refined filtration black tea and bag filter inwall is several
Rate, make dust be easier to come off, improve production efficiency, further, it is preferable to when vibration frequency is 160 times/min, obtained
Black tea it is the purest, and caused vibrations noise is minimum when bag filter 3 is run, and the influence to environment is also minimum, protects
The safe handling of equipment is protected.
