A kind of beer saccharification filter device that utilizes the coiled pipe heating
Technical field
The utility model relates to the brewage field, particularly a kind of beer saccharification filter device of beer bierstube.
Background technology
Existing beer bierstube wheat juice preparation system has generally included saccharification filter vat and hot-water cylinder based on two devices and three devices.Referring to the applicant's Chinese invention patent application ZL200810059200.9 disclosed " a kind of combined preparation device for beer wort ".
Fructus Hordei Germinatus utilizes in the saccharification filter vat that hot water carries out saccharification in the hot-water cylinder, and no heating unit still is relatively tradition and a popular form in beer bierstube's sacchariferous equipment in the saccharification filter vat.
The benefit of this form is that the saccharification filter vat does not need heating jacket, does not also need mechanical stirring, coking phenomenon can not take place.But also there is following problem:
Material and external environment generation thermal conduction and radiative transfer in saccharifying because in the groove, temperature of charge is difficult to keep constant in continuous reduction in the groove.So just brought a lot of problems: at first owing to the reduction of temperature, Fructus Hordei Germinatus can not be incubated the sufficiently long time at the highest temperature section of enzymic activity, causes saccharification yield to descend; Secondly because temperature reduces, poor layer can shrink, and causes filtration difficulty; Its three, can only carry out single temperature saccharification, can not realize the diversity of beer bierstube's making method; Its four, first saccharification refilters, it is long to account for pot time.
The utility model content
Technical problem to be solved in the utility model is the present situation at prior art, and a kind of saccharification filter device that can keep constant temperature and can carry out the saccharification of many temperature in saccharifying is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the utility model utilizes the beer saccharification filter device of coiled pipe heating, it includes saccharification filter vat and hot-water cylinder, the top, the jar end of saccharification filter vat is provided with and is used for filtering sieve plate, the jar end that it is characterized in that described saccharification filter vat, be provided with the outlet of wheat juice, also be provided with wheat juice refluxing opening on the saccharification filter vat, and this wheat juice refluxing opening is positioned at the top of described sieve plate; Be provided with coiled pipe in the described hot-water cylinder, the outlet of the wheat juice of this coiled pipe connects wheat juice refluxing opening on the described saccharification filter vat by pipeline, and its wheat juice import then connects wheat juice outlet on the saccharification filter vat by pipeline, and the pipeline between the two is provided with impeller pump.
Described saccharification filter vat and described hot-water cylinder are the branch body structure that is provided with separately separately.
Described saccharification filter vat and described hot-water cylinder be a saccharification filter vat last and hot-water cylinder under the integral type Composite Can, and the top of described hot-water cylinder is that double as is the jar end of described saccharification filter vat.This structure helps saving the occupation of land space of material and minimizing equipment for minute body structure.
Be provided with the first Temperature Measure Control device in the described saccharification filter vat.
Be provided with the second Temperature Measure Control device in the described hot-water cylinder.
The utility model has been owing to set up coiled pipe in hot-water cylinder, thereby the wheat juice in the saccharification filter vat can be heated once more, thereby keeps the constant of temperature in the saccharification filter vat, realizes the constant temperature in the wheat juice saccharifying.And, can also pass through to regulate the temperature of hot water in the hot-water cylinder, and make saccharifying be in different thermostat temperatures, thereby realize many temperature saccharification of wheat juice in the different stages.In brief, its implementation procedure is: in saccharifying, when temperature of charge is lower than design temperature in the saccharification filter vat, just allow wheat juice flow through coiled pipe in the hot-water cylinder, utilize the temperature head of wheat juice and hot water to conduct heat, stop after reaching design temperature.In addition, the formation of layer on sieve plate because wheat juice by circulating in the coiled pipe, can promote to be pickled with grains or in wine in the saccharification later stage is so can save filtration time.
In sum, the utility model mainly is to increase coiled pipe and corresponding circulation line in hot-water cylinder, thereby the handiness that improves saccharification quality and production technique can also shorten accounting for a pot time.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, present embodiment utilizes the beer saccharification filter device of coiled pipe heating, and it includes saccharification filter vat 1, hot-water cylinder 2 and is placed on coiled pipe 3 in the hot-water cylinder 2.Saccharification filter vat 1 is top end sharing structure with hot-water cylinder 2, be a saccharification filter vat 1 last and hot-water cylinder 2 under the integral type Composite Can, and the top double as of hot-water cylinder 2 is jar end 11 of saccharification filter vat 1.
The top, the jar end of saccharification filter vat 1 is provided with and is used for filtering sieve plate 12, and the space between jar top, the ends 11 and the sieve plate 12 has funnel shaped wheat juice liquid collecting zone 13.Also be provided with the first Temperature Measure Control device 14 in the saccharification filter vat 1.
The jar end 11 of saccharification filter vat 1, be provided with wheat juice outlet 15, and the sidewall of saccharification filter vat 1 is provided with wheat juice refluxing opening 16, and this wheat juice refluxing opening 16 is positioned at the top of described sieve plate 12; Be provided with described coiled pipe 3 in the described hot-water cylinder 2, the two ends of coiled pipe 3 are respectively wheat juice import 31 and wheat juice outlet 32.The outlet 32 of the wheat juice of this coiled pipe 3 connects wheat juice refluxing opening 16 on the described saccharification filter vat 1 by the pipeline (not shown), its wheat juice import 31 then exports 15 by the wheat juice that pipeline connects on the saccharification filter vat 1, and the pipeline between the two is provided with the impeller pump (not shown).
Steam inlet 22 and condensation-water drain 23 that hot-water cylinder 2 has steam jacket 21 and is connected with chuck 21 are provided with the second Temperature Measure Control device 24 in jar.
In the saccharification filtration procedure, hot-water cylinder 2 keeps the design temperature of jar interior hot water by the steam break-make of its Temperature Measure Control device 24 control steam jackets 21.
When finding that material is lower than the setting technological temperature in the groove, the Temperature Measure Control device on the saccharification filter vat 1 14 wheat juice is squeezed into coiled pipe 3 by wheat juice outlet 15 by the impeller pump in the start-up system, wheat juice enters wheat juice refluxing opening 16 from wheat juice outlet 32 then, stops after the temperature of charge of this circulation in saccharification filter vat 1 reaches set(ting)value.
In the middle of this process, owing to the temperature difference produces heat exchange, the temperature in the saccharification filter vat 1 just can be elevated to set(ting)value to the hot water in the saccharification filter vat 1 in wheat juice and the hot-water cylinder 2 like this in coiled pipe 3.Simultaneously, beat in the middle of the cycle heat exchange process at wheat juice that wheat is poor to form filtering layer gradually on sieve plate 12, finish when filtering, just needn't carry out wheat juice again and circulate, saved the time when saccharification.
