Fermentation unit comprises fermenting case 2, drawing mechanism 3, breaks up device 4 and conveying device 5.Fermenting case 2 comprises that four outside plates 21 surround the fermenting case main body that forms, and is surrounded by four interior orifice plates 22 in fermenting case 2 and is an interval with outside plate 21, forms the air chamber 223 of an annular.The two ends up and down of air chamber 223 are airtight.Be provided with a bottom of slidably removing 31 in the bottom of fermenting case 2, be provided with a threaded silk seat 33 at this bottom 31.Outside plate 21 is provided with the ventilation duct 25 of a connection air chamber 223 therein, and these ventilation duct 25 other ends are communicated with external heated blower fan (not showing on the figure) and oxygen generator (not showing on the figure), make extraneous air lead to air chamber, and then feeds inner chamber.Be provided with a deep bead 222 at the interior orifice plate direct relative with ventilation duct, prevent that local air flow from directly contacting and yeast-bitten with fermentation raw material in a large number.In ventilation duct 25, be provided with atomizer 26, keep the skin wet fast by the high-pressure atomization humidification, to carrying out humidity regulation in the fermenting case 2.In fermenting case 2 inner chambers that surrounded by interior orifice plate 22, be provided with temperature and humidity sensing 23 and oxygen concentration sensor 24.Be evenly equipped with a large amount of pore 221 at interior orifice plate 22, fermenting case 2 inner chambers that make air chamber 223 and interior orifice plate 22 surround formation are communicated with.
Conveying device 5 comprises the guide rail 54, the support 55 that are arranged on the frame 1, be arranged on chute feeder 51 on the support 55, carry motor 59, by the roller 56 of carrying motor 59 to drive and rolling at described guide rail 54 be arranged on travel switch 58 on the guide rail 54.The guide rail 54 that is arranged on the frame 1 is two, is set in parallel, and roller 56 is four and is and is arranged in twos on the support 55.Travel switch 58 is arranged on therein on the guide rail 54, and sets up the both sides of a roller 56 therein separately.In the present embodiment, carry motor 59 to drive roller 56 by a chain drive 57 and roll at guide rail 54, carry motor 59 to commutate according to the travel switch 58 of roller 56 touchings, conveying device 5 is moved back and forth at guide rail 54.Arranging apart from corresponding with the width of discharging opening 42 of travel switch 58.Chute feeder 51 is connected on the support 55 by elastic plate 53, and be provided with vibrator 52 in the bottom of chute feeder 51, and chute feeder 51 is vibrated in course of conveying, carry fermentation raw material to move along chute feeder 51, and play secondary and break up effect, the fermentation raw material that drops on the chute feeder 51 is laid evenly.By reciprocating motion and the vibration of conveying device 5, fermentation raw material can be dropped in the fermenting case 2 of next stage fermentation unit at more uniform stand.
During work, utilize outer elevator (not showing on the figure) and the conveyer belt of weighing (not showing on the figure) of joining that tea raw material is sent in the one grade fermemtation case 2, at this moment, with addition of air-heater (not showing on the figure) and oxygen generator (not showing on the figure) work, air-flow carries the required an amount of temperature of fermentation, oxygen in ventilation duct blows into the air chamber 223 of fermenting case 2 outward.After avoiding air-flow to have breather pipe 25 to come out, air quantity is excessive in the scope of the direct corresponding region of the mouth of pipe causes local fermentation transition, is provided with deep bead 222 at this place.When air-flow blows to deep bead 222, begin around air chamber, to shunt, make air chamber internal pressure field even.
Along with the increase gradually of blast in the air chamber 223, air-flow begins to be blown into and to connect fermentation raw material inside by the pore 221 at interior orifice plate 22 four sides, and is discharged by fermenting case 2 open tops, makes in the fermenting case 2 the tea raw materials obtain fermenting temperature required, and oxygen fully contacts.
Temperature Humidity Sensor on the inboard of deep bead 222 and oxygen concentration sensor can be surveyed humiture and oxygen concentration.When humidity is lower than 90%, 26 work of high-pressure atomization nozzle.Atomized steam enters fermentation raw material inside with air-flow, keeps wetting balance.When oxygen concentration was too high, oxygen concentration sensor fed back signal to control system (not showing on the figure), stopped outside oxygen generator (not showing on the figure) work.
When appropriateness is arrived in fermentation, drawing mechanism 3 work.Discharging motor 34 cooperates by rotational lead screw 32 and by the screw pair with silk seat 33, and bottom 31 is moved horizontally along leading screw 32 directions.Fermentation raw material falls into to be broken up in the device 4, and the tealeaves after breaing up drops on the chute feeder 51 of conveying device 5.Chute feeder 51 drops in the fermenting case 2 of next stage fermentation unit at the stand fermentation raw material by moving back and forth and vibration uniformly.
After fermentation raw material enters down single order fermenting case 2, will continue continuity higher level fermentation, finish until fermentation.At this moment, begin the new raw material of packing into again in the fermenting case 2 of higher level's fermentation unit of vacating, beginning is fermentation for the first time.
The staged series connection mode of continuously fermenting can improve the uniformity of fermentation efficiency and fermentation quality, and the continuity fermentation is beneficial to the realization of automatic assembly line operation.When amount of fermentation is big, can be with multistage fermentation unit parallel connection, the work of many groups improves output.
Specific embodiment is in order more to be expressly understood the utility model, not as a kind of restriction to the utility model right, under the prerequisite that does not break away from the utility model aim, various variations can be arranged, and all these will be included within the scope of this claim the apparent modification of described those skilled in the art.
