Description
Technical Field
The invention relates to the field of beer brewing, in particular to an automatic hop adding device and an automatic batch adding method.
Background
In the process of brewing beer, hops are indispensable raw materials, and the hops of different varieties can provide special aroma and bitter taste for the beer. Meanwhile, the bitter taste, flavor, aroma and the like of the hop contributing to the beer are different according to the adding time. In large volume breweries hops are usually added during the wort boiling stage. Hops can be divided into granular hops, hop extracts and the like, and the granular hops are generally used in the beer market at present. The granular hops are very easy to oxidize substances and need to be stored in a low-temperature oxygen-insulating environment, otherwise, the granular hops are slowly oxidized by contacting air and lose original bitter taste.
In the early stage of beer development, the boiling pot is boiled at normal pressure, and the hop is added into the boiling pot directly by opening a feeding port at the top of the boiling pot. At the present stage, most of beer factory boiling pots adopt a low-pressure dynamic boiling mode, so that hops cannot be directly added from a feeding port, and the hops are added in a way of circulating dissolving of a hop circulating tank wheat juice. The specific form is that in the boiling period of a boiling pot, particulate hops are manually taken out from a hop storage bank and added into a hop circulating tank, and three hop circulating tanks are prepared when three hops are required to be added in the boiling period of a common factory. Adding hops into the circulation tank, introducing the wort into the circulation tank through a pump to dissolve the hops, and recycling the hops into the boiling pot to dissolve the hops into the wort.
However, the hop adding mode of the hop circulating tank has the following four problems: (1) one boiling period is about two hours, hops need to be transported from the hop storage warehouse and added to the hop circulating tank every two hours on average, the frequency of manual labor is high, and the method belongs to repeated labor. Before hops are added to the boiling pot each time, an operator needs to obtain an instruction of a central control room, and the operator basically stays in a standby state all the time; (2) the hop circulating tank and the circulating pipeline thereof both have a certain amount of residual wort after the wort is boiled and the boiling pot is emptied. The four boiling periods are one shift, cleaning is carried out after the shift is finished, a certain amount of wort is lost in one shift, two shifts are carried out in one day on average, and three shifts are carried out in a peak period. Meanwhile, after a shift is finished, the boiler is cleaned, and the hop circulating tank and the circulating pipeline thereof must be cleaned, so that certain cleaning liquid consumption is caused, including the use of cleaning alkali liquor and cleaning water, and considerable economic loss is caused by the loss of wort and the loss of cleaning water after day and year from the perspective of cost; (3) the hop adding amount each time is manually weighed, errors may occur in manual metering, manual error points are increased, if the hop adding amount is wrong, the indexes of the wort in the whole boiling pot are affected, and the product quality of the boiled wort is reduced; meanwhile, the mode of metering by an electronic scale cannot automatically record the addition amount of hops each time, and cannot perform quality tracing analysis on the boiling pot hop addition production process; (4) different hops are manually added into different hop circulating tanks each time, the hop circulating tanks are three, workers can make mistakes and add wrong circulating tanks under the condition of long-term feeding, so that the adding time of the different hops is not right, the production process of the boiled wort is greatly influenced, the bitter taste and the fragrance of the wort in the boiling period can not meet the production requirement, the quality of the wort is reduced, the whole pot of wort can be scrapped in an extreme case, and the economic loss is disastrous.
