Abstract

The beer making technological process includes the steps of saccharifying malt, filtering, boiling, cooling, fermentation, filtering to produce clear beer, packing, etc. There is one hop product adder mounted to add hop product at relatively low temperature of 4-8 deg.c in the last adding step. The lowered hop product adding temperature reduces the loss of the fragrance in hop product with evaporating water, and this raises the quality of beer product and makes the beer product more fragrant and delicious. The hop product adder is simple, practical and easy to install.

Description

A kind of beer new preparation process

That the present invention relates to is beer preparation technology.

In the making method process of beer, traditional beer brewing technique is earlier with malt amylase, filters the back and boils at 100 ℃, adds hops and hop product in the process of boiling, then through cooling, fermentation, filter, make pure mellow wine, the packing back is a finished product.The boiling time of wheat juice was generally 1-1.5 hour, and the interpolation of last hop product is in order to increase the fragrance of beer, to be referred to as blending.The interpolation of last hop product is under the high-temperature boiling state in Wort boiling (100 ℃) pot in this technology, hop product is added in the boiling pot together with raw material boil, and after the cooling, goes into fermentor tank adding saccharomycetes to make fermentation by the materail tube linear flow.Although the time of boiling after the last hop product adds is short, the most of fragrance of determining in the hop product is pulled away along with the evaporation of moisture, has 80% even 90% fragrance therefore to lose in the hop product approximately, has seriously influenced the quality of wine product.For these years, the beer production is followed such manufacture method always and is produced beer.

The objective of the invention is this traditional beer preparation technology improved a kind of beer new preparation process is provided, change the addition manner of last hop product among the traditional beer preparation technology by this novel process, reduce the loss of hop product fragrance, improve the quality of beer product.

The objective of the invention is to realize by following technical scheme: the beer new preparation process is to adopt cold wheat juice method, the last that is hop product adds the interpolation of employing low temperature, concrete way is that the hop product adder is installed in perforate additional on the material material pipeline of flowing through when entering fermentor tank, the tremie pipe of hop product adder inserts in the material pipeline, behind saccharification wort, through boiling, cooling back temperature is 4-8 ℃, when the fermentor tank charging, opening the hop product adder simultaneously makes hop product in the feed pot along with the Flow of Goods and Materials in the material pipeline enters fermentor tank together, the last that carries out hop product adds, and the optimum temps that last adds is 5 ℃.Such addition manner and interpolation temperature promptly have the better protecting effect to the yeast that uses in the following road fermentation procedure; be unlikely to make yeast to lose efficacy; because the last of hop product interpolation temperature is lower, and the fragrance of hop product is pulled away with the water evaporates of boiling.

The interpolation of hop product is to be undertaken by the hop product adder.

The last that the present invention has changed hop product adds temperature, the fragrance that such addition manner has reduced hop product is evaporated the chance of loss with moisture, and the quality of beer product is improved, and the beer of production gives off a strong fragrance, mouthfeel is better than the beer of former explained hereafter, and quality is superior; The simplicity of design practicality of hop product adder, cost is low, does not occupy floor area, consumption of power not, installing does not influence ordinary production.

The invention will be further described below in conjunction with the drawings and specific embodiments:

Fig. 1 is the former process drawing of the present invention;

Fig. 2 is a process drawing of the present invention;

Fig. 3 is the structural representation of hop product adder among the present invention;

Fig. 4 is the structure vertical view of hop product adder among the present invention.

1 feed pot, 2 feed hoppers, 3 needle type valves, 4 tremie pipes, 5 material pipelines among the figure

Embodiment 1:

The hop product adder is made up of feed pot 1, feed hopper 2, needle type valve 3, tremie pipe, feed hopper 2 is installed in feed pot 1 open top, tank body 1 bottom opening is installed needle type valve 3, connects tremie pipe 4, and there is a camber tremie pipe 4 ends along the flow direction of material.Enter on the material pipeline 5 of fermentor tank after the hop product adder being installed on the cooling of wheat juice earlier, 2/3 place that tremie pipe 4 inserts in the material pipeline 5, hop product is packed in the hop product adder.The saccharification of Fructus Hordei Germinatus elder generation is filtered the back and is boiled at 100 ℃, and boiling time 1-1.5 hour, added hops this moment in boiling pot, and its purpose reduces the foam in the Wort boiling pot, anti-Spill stopping pan, sterilization.Boil the back wort filtration, when being cooled to 5 ℃ to the fermentor tank charging, the needle valve of opening the hop product adder simultaneously adds hop product, allow hop product enter fermentor tank together in company with the Flow of Goods and Materials in the material pipeline 5, regulate the fragrance of beer, through fermentation, filtration, make pure mellow wine, the packing back is a finished product, and proportioning raw materials and other processing condition do not change.

Embodiment 2:

Hop product adder and installation thereof are with embodiment 1.The saccharification of Fructus Hordei Germinatus elder generation, filter the back and boil at 100 ℃, boiling time 1.5 hours adds hops this moment in boiling pot, purpose is with embodiment 1, to the fermentor tank charging, the needle valve of opening the hop product adder simultaneously adds hop product, allows hop product enter fermentor tank together in company with the Flow of Goods and Materials in the material pipeline 5 when boiling back wheat juice, heat exchange postcooling to 4 ℃, fermentation, filtration, make pure mellow wine, the packing back is a finished product, and proportioning raw materials and other processing condition do not change.

Embodiment 3:

The hop product adder is installed with embodiment 1.The saccharification of Fructus Hordei Germinatus elder generation, filtering the back boils at 100 ℃, in the wheat juice pot that this moment, hops divided secondary to be added into to boil, purpose is with embodiment 1, in the time of will boiling back wheat juice, heat exchange postcooling to 7 ℃ to the fermentor tank charging, the needle valve of opening the hop product adder simultaneously adds hop product, allow hop product enter fermentor tank together in company with the Flow of Goods and Materials in the material pipeline 5, pure mellow wine is made in fermentation, filtration, the packing back is a finished product, and proportioning raw materials and other processing condition do not change.

The finished beer of three kinds of addition manner productions gives off a strong fragrance, and mouthfeel all is better than the beer of former explained hereafter, and wherein adding temperature with the last hop product is that 5 ℃ embodiment 1 is an optimum.

Claims

1, a kind of beer new preparation process, its technological process be Fructus Hordei Germinatus through saccharification, filter, boil, cool off, ferment, filter and pack after making pure mellow wine, on the material pipeline (5) when wheat juice enters fermentor tank after boiling, cooling off the hop product adder is housed, it is characterized in that: it is to adopt low temperature to add that the last of hop product adds, and adding temperature is 4-8 ℃.
