Description
Technical field
The present invention relates to a kind of wheat juice continuous processing apparatus and wheat juice continous treatment process.
Background technology
In the past, proposed to have following a kind of wheat juice continuous processing apparatus and wheat juice continous treatment process (not drawing continuous conversion technique) (please refer to Fig. 3).In this technique, first the wheat juice after filtering is heated in temporary tank 1, make temperature rise to 100 DEG C from 78 DEG C.Then these 100 DEG C of wheat juice are delivered in generation tank 2 continuously by pump.Hops are online between temporary tank 1 and generation tank 2 quantitatively to be added.Generation tank 2 is equipped with agitator and direct steam injection device, and under 100 DEG C of-104 DEG C of temperature condition, wheat juice is incubated 45 minutes in generation tank 2.Be delivered to continuously afterwards in settling tank 3 heat of dissociation coagulum and clarification wheat juice.Settling tank 3 is pyramid type tank, and the import of wheat juice is positioned at at cone the end, and is equipped with a static press device help throw out precipitation.This throw out transfers out from settling tank 3 bottoms continuously by pump, and is recovered utilization.100 DEG C of wheat juice after settling tank 3 is clarified 45 minutes, continuously by pump delivery to stripping tower 4, and effectively remove bad volatile matter with live steam convection current.Overhead vapours is by the cooling rear discharge of condenser 5.Wheat juice after steam stripped, is delivered to continuously and in water cooler 5, is carried out continuously coolingly in stripping tower 4, then enters fermentation unit 6.
But, not drawing in continuous conversion technique, although whipping appts is installed in generation tank 2, due to wheat juice flow pattern in tank, differed wheat juice residence time in tank, and then make wort quality produce fluctuation.The stripping stage need to be removed volatile component and supplement the energy that reduces loss due to clarification phase temperature with saturation steam, so consume a large amount of steam; Stripping tower complex structure, operation inconvenience; After stripping, wheat juice temperature raises, and increases the refrigeration duty of cooling workshop section.
In the past, also proposed to have following another kind of wheat juice continuous processing technique (please refer to Fig. 4).In this kind of technique, 75 DEG C of wheat juice after filtration are by interchanger 2 and 3 laser heatings to 100 DEG C or slightly exceed the temperature of 1-3 DEG C, to offset the thermosteresis in plug flow boils tower 4.The steam that interchanger 2 adopts stripping tower 5 to discharge heats.Interchanger 3 adopts live steam heating.Wheat juice after heating is delivered to plug flow and boils tower 4.It is cylindrical containers that variable frequency control agitator motor and rotating disk are installed that plug flow boils tower 4.It can be from top or bottom feed, and this explanation adopts bottom feed to facilitate stripping tower 5 strippings.For the residence time that ensures that wheat juice boils tower 4 at plug flow, establish material outlet in its equipment different heights position.Saturation steam is controlled flow by reducing valve and variable valve 8, and flow velocity is set as a fixed percentage of stripping stage material flow, to obtain, stripping tower 5 falls without pouring or the optimum operating condition of liquid flooding.Afterwards, saturation steam enters stripping tower 5 and forms adverse current with material, and bad volatile constituent is taken away by stripping.The steam that leaves stripping tower 5 can directly discharge, and also can heat and partial condensation by heat exchanger 2, or associating interchanger 2 and 6 carries out total condensation and becomes liquid to carry out wastewater treatment.Pressure transmitter 7 and variable valve 8 are combined to be made for ensureing the control to stripping process.After stripping, wheat juice is delivered to surge tank 11 by pump 9, is transported to afterwards hot trub segregation section 10 and carries out hot trub separation and clarification wheat juice, then carries out wheat juice cooling process again.
This technique has realized Wort boiling, processing and cooling continuity, has shortened the process time, and will boil function by rotating disc type plug flow boil tower generate and stripping tower stripping two portions realize.Compare the above-mentioned generation tank not drawing in continuous conversion technique, rotating disc type plug flow boils tower and is stirred and obviously improved the homogeneity of material in equipment and the homogeneity of the residence time by rotating disk, has ensured quality product.While wheat juice boils at plug flow can be in malleation not boiling state in tower, and this has great role to preventing equipment because fouling occurs the boiling of wheat juice, and then ensures to produce continuously and be easy to cleaning, reduction thermal load.Stripping process is the same with the above-mentioned continuous conversion technique of not drawing, and effectively reduces volatile constituent content, particularly DMS (dimethyl sulphide) content in wheat juice by saturation steam stripping.But the rotating disc type plug flow in this technique boils tower design relative complex, and its rotating disk needs additionaling power with revolution.The stripping stage need to be removed volatile component with saturation steam, consumes a large amount of steam; Stripping tower complex structure, operation inconvenience; The deficiencies such as after stripping, wheat juice temperature raises, the refrigeration duty of increase refrigerating work procedure.
In the past, also proposed to have another following wheat juice continuous processing technique (please refer to Fig. 5).The wheat juice making from previous process enters temporary tank 1, and approximately under 5.5bar pressure, is being delivered to reaction tubes system 4 by pump 2.Wheat juice, before entering reaction tubes system 4, is heated to 140 DEG C of boiling temperatures by direct steam injection in advance in steam-Mai juice well heater 3, and the thing of hop extraction simultaneously adds by pipeline 10a and 10b online by quantitatively adding pump 9.Wheat juice is after reaction tubes system 4 stops 4 minutes, and overheated wheat juice is delivered in expansion drum 6 through throttling valve 5, and pressure is reduced to 1bar left and right.This overheated wheat juice enters that expansion drum 6 is rear to be distributed in whole cross section relatively equably, and the steam bubble stripping forming by means of pressure decreased 0.75 meter of dark wheat juice in expansion drum 6, thereby realize, bad volatiles is removed.Stripping gas enters atmosphere or is re-used from vapor pipe 7.95 DEG C of hot wheat juice after stripping are delivered in settling apparatus through pump 8, and heat of dissociation coagulum and clarification wheat juice, carry out cooling afterwards.
This technique has realized Wort boiling equally to cooling continuity, has greatly shortened the wort preparation time and has reduced cleaning process, improves throughput.Wort boiling function by online open steam heat, reaction tubes system stop and stripping process complete.Although the high temperature Wort boiling in this technique is improving quickening greatly at temperature, but use the significantly 120-160 DEG C of temperature range higher than the temperature range (100-108 DEG C) of current wort preparation, can cause a series of shortcomings such as increase, reducing substances oxidation such as the rising of wheat juice colourity, HMF (hydroxymethylfurfural), DMS (dimethyl sulphide).In addition, in reaction tubes system, high temperature wheat juice easily makes protein precipitation generation serious scale, once occur will be difficult to clean to cause producing and interrupting continuously, runs counter to operate continuously requirement.

As shown in Figure 1, flash tank 4 is also connected with vacuum cooler-condenser 8, and vacuum cooler-condenser 8 is connected with vacuum pump 9.Vacuum pump 9 extracting airs make flash tank 4 produce negative pressure, and in arriving certain pressure, after the flash-off steam in flash tank 4 exchanges by vacuum cooler-condenser 8, steam becomes water of condensation, volume-diminished, and pressure decreased, and then maintain vacuum state.
Clarifying tank 5 is also connected with turbid juice tank 11, and turbid juice pump 10 is installed on the pipeline of clarifying tank 5 and turbid juice tank 11, for being transported to turbid juice tank 11 from the turbid juice of clarifying tank 5.
It is cooling that water cooler 6 utilizes frozen water to carry out the wheat juice from clarifying tank 5, and discharge hot water.The cooled wheat juice of the device 6 that is cooled utilizes wheat juice pump 7 to be transported to fermentation unit, ferments.
Below, the technological process of this example is illustrated as follows.
Specifically, the wheat juice after brewing room filters is stored in surge tank 1, and the temperature of this wheat juice is generally 72-78 DEG C, through adopting steam-heated well heater 2 to be heated to 100 DEG C, and is imported into and boils in tower 3.Utilize static pressure because boiling tower 3 in interior, thereby reach boiling state after avoiding wheat juice to enter boiling tower 3, avoid wheat juice protein precipitation to cause and boil tower 3 foulings.Again, boil that tower 3 is interior has installed some column internalss 31, be used for ensureing that wheat juice is the homogeneity of plug flow regime and the residence time,, make every part of the wheat juice after heating rest on and boil the inside of tower 3 and boil with the identical time, but also utilize this to boil the direct steam injection device 32 in tower 3, compensation thermosteresis, improves flow pattern.
Boiling in tower 3 and stopping after certain hour in 98-100 DEG C of wheat juice, be delivered to immediately vacuum tightness and be-flash tank 4 of 0.4bar in flash distillation.The wheat juice boiling in tower 3 enters flash tank 4 by the effect of wheat juice pump 7 along tank body tangential way.Under vacuum state, wheat juice evaporates rapidly, and acutely boiling, effectively removes the unpleasant odor materials such as DMS (dimethyl sulphide) in wheat juice.Wheat juice self temperature after flash distillation is reduced to 85 DEG C from 100 DEG C, and is delivered to immediately in clarifying tank 5 heat of dissociation coagulum and clarification wheat juice.Hot trub is delivered in turbid juice tank 11 by turbid juice pump 10, adds in right amount washing wheat juice wherein at filtration stage.Clarification wheat juice be delivered to continuously in water cooler 6, carry out cooling.
Below effect of the present invention is described.
Hot wheat juice in the present invention after boiling is directly delivered to flash distillation immediately in flash tank 4, and front and back are to carry out continuously, and the time is shorter, and calorific loss is very little, even can ignore, and in flash vaporization process, not need additionally to increase thermal source again.
Again, enter flash tank 4 through the hot wheat juice that boils tower 3 with tangential direction, at the large generating surface of a parabola form of the interior formation of evaporating pot 4, flash evaporation rapidly under vacuum state, violent boiling, effectively remove the unpleasant odor materials such as DMS (dimethyl sulphide), and then ensure beer quality.In addition, wheat juice by vacuum flashing after self temperature be reduced to 85 DEG C from 100 DEG C, do not need to provide extra steam to carry out stripping.
Again, flash tank 4 is simple in structure, processing ease.Just conventional containers of flash tank 4, not special construction, vacuumized and made flash tank 4 reach certain vacuum degree (as-0.4bar) by vacuum pump 9 in use, wheat juice flash distillation normal operation final vacuum pump 9 can not opened, and only uses vacuum cooler-condenser 8 can reach corresponding vacuum tightness.Like this, the control of flash tank 4 more easily realizes automatization.
Again, the wheat juice temperature after vacuum flashing is only 85 DEG C, enters in clarifying tank clarifying process in lesser temps, has reduced thermal load TBA (thiobarbituricacidα-) etc., safeguards wheat juice performance.
Again, after flash distillation precipitation, wheat juice temperature is lower, thereby the refrigeration duty of cooling workshop section is little, comparatively energy-conservation.Wheat juice temperature after vacuum flashing precipitation is only 85 DEG C, is cooled to ferment under required certain temperature (5-8 DEG C) at wheat juice, and the refrigeration dutys such as the required frozen water of lesser temps of the rear wheat juice of flash distillation precipitation are less, reduce energy expenditure and production cost.
Above, best example of the present invention is illustrated, but the invention is not restricted to described example.About concrete structure, not departing from the scope of aim of the present invention, can carry out suitable change.
In above-mentioned example, flash tank is connected with vacuum cooler-condenser, and vacuum cooler-condenser is connected with vacuum pump, but the invention is not restricted to this, flash tank also can directly be connected with vacuum pump, and the air constantly extracting in flash tank by vacuum pump keeps the vacuum tightness in flash tank.As long as the structure that makes flash tank carry out flash distillation to wheat juice under vacuum state, any can.
