Description
Technical Field
The utility model relates to the technical field of beer brewing, in particular to a weak wort recycling system.
Background
Beer brewing involves eight major steps. In the first step, the raw materials are prepared, malt is ground, and the ground malt is mixed with hot water. In a second step, the saccharification process, the mixture is heated to a suitable temperature to promote the activity of the enzyme such that the enzyme breaks down the starch into sugars, forming sweet wort. And thirdly, filtering the saccharified liquid, and filtering the saccharified liquid through a filter screen to remove dregs and solid particles, thereby obtaining clear liquid. Fourth, boiling and adding hops, boiling the saccharified liquid, and adding hops during the boiling process. And fifthly, cooling and fermenting, namely rapidly cooling the boiling liquid to a fermentation temperature, adding yeast into the boiling liquid, and transferring the yeast into a fermentation tank for fermentation. Sixth, a maturation step, in which the beer is stored in a low temperature environment, in order to improve its taste and stability. Seventh, filtering and carbonating, filtering to remove residual solid particles and suspended matters, and injecting carbon dioxide to obtain proper carbonic acid gas content of beer. And eighth step, filling and packaging.
In the third step, hot water is added into the filter tank to wash sugar contained in the filter residue, and when the boiling pot reaches the full pot volume, the filtering is finished. Typically, the residue remaining in the filter tank is discharged and sold as a by-product. However, at the end of the filtration, there is still a portion of wort containing sugar in the filter tank, the wort concentration being below 5°p, also called weak wort.
In order to sufficiently wash out sugar in filter residues in the filter tank, the flushing water amount often reaches about 35% of the volume of a saccharified single batch, and the weak wort reaches 350HL according to 1000HL per batch. In the use of weak wort, most breweries use the weak wort for flushing the next batch of filter tanks, in the use scheme, the weak wort needs to be stored for 2-3 hours at 76-78 ℃ to continuously carry out Maillard reaction, and the taste and freshness of the wort are affected.
In the use of weak wort, there is another scheme, namely a scheme of using weak wort for saccharification and gelatinization feeding, and the gelatinization process is a process of forming viscous paste by rapidly swelling starch particles after heating and breaking cell walls after heating to a certain temperature; saccharification refers to the process of converting starch into sugars such as glucose, maltose, maltotriose, and the like by amylase. The gelatinization feeding temperature is about 60 ℃, and the saccharification feeding temperature is about 46 ℃, so that the weak wort at 76-78 ℃ can be used for feeding after being mixed with normal-temperature or low-temperature brewing water, the weak wort is diluted after mixing, only 1/3 of the weak wort can be actually used for feeding, and the weak wort utilization rate is lower due to high normal-temperature water temperature in summer of producing strong seasons. Meanwhile, in the process of mixing and cooling, heat energy carried by the weak wort is wasted, and sustainable development is not facilitated.

Beer factories generally strive for minimal extract losses, whereas many factories have total extract losses of over 2.5% over a long period of time. Among them, in the saccharification stage, the extract loss in this stage tends to have a great influence on the plant due to the high-concentration brewing.

The weak wort will reach 350HL per batch calculated at 1000HL (HL refers to hundred liters). Part of factories use weak wort for the next batch of filtering and washing grains, and the utilization mode ensures that the weak wort needs to be stored for 2-3 hours at 76-78 ℃ to influence the taste and freshness of the wort.
