Description

Mixed preparation process for processing instant beverage Technical Field The invention relates to the technical field of coffee mixing, in particular to a mixing preparation process for processing instant beverage. Background Coffee is taken as a globally popular drink, and occupies a wide consumer market by virtue of the unique mellow taste and remarkable refreshing effect. However, for traditional coffee, the coffee beans are hot due to the bias of the nature after baking, so that the symptoms of excessive internal heat are easily caused after long-term drinking, the coffee is prominent in bitter taste and single in flavor level, and the diversified taste demands of consumers are difficult to meet, in order to enrich the flavor of the coffee and improve the drinking side effects of the coffee, the industry generally tries to add herbal ingredients into the coffee, the natural characteristics of the herbal ingredients are utilized to neutralize the warm nature of the coffee, and meanwhile, the multi-element flavor and the medicinal auxiliary value of the product are endowed, so that the Chinese herbal composite coffee becomes a new consumption trend. However, in the existing herbal and coffee composite processing, as most of the herbal plants are cellulosic materials, the powder formed after the conventional treatment and the coffee powder have differences in density and particle size distribution, so that the Chinese herbal composite coffee has high requirements on the mixing of the coffee powder and the herbal plants, and layering or agglomeration is very easy to occur if the mixing of the Chinese herbal composite coffee and the coffee powder is uneven. In the prior art, most of mixing is realized by adopting a stirring blade to stir, but the uniformity achieved by adopting the mode cannot meet the requirement of Chinese herbal composite coffee on uniformity, the uniformity of the mixed product is easy to be poor, the batch stability is insufficient, herbal fibers are easy to precipitate and coffee powder is easy to float upwards during brewing, the drinking experience is influenced, in addition, the conventional mixing equipment adopting the stirring blade is designed to have single motion trail, the mixing dead angle exists, the deep fusion of two kinds of powder with obvious characteristic difference cannot be realized, and the mixing difficulty is further aggravated. Therefore, a set of targeted preparation process needs to be developed, and the problems that herb fibers are easy to precipitate and coffee powder is easy to float up during brewing caused by uneven mixing of the herb and the coffee powder are solved by optimizing a mixing link. Disclosure of Invention The object of the present invention is to provide a hybrid preparation process for the processing of instant beverages which does not have at least one of the drawbacks mentioned above. In order to achieve the above purpose, the invention provides a mixed preparation process for processing instant beverage, which comprises the following steps: s1, pretreatment of plant herbal raw materials and preparation of paste powder, wherein the preparation method comprises the steps of sequentially carrying out ultrasonic cleaning, decompression decoction, paste collection, low-temperature drying and low-temperature crushing on the plant herbal raw materials to obtain herbal paste powder; S2, adopting the existing instant coffee pulverizing process, selecting the matched coffee beans, grinding, extracting and drying to prepare coffee powder, and ensuring that the original flavor and refreshing components of the coffee are reserved; S3, accurately mixing, namely respectively pouring the herbal paste powder prepared in the step S1 and the coffee powder prepared in the step S2 into two feed hoppers in a premixing mechanism, wherein the herbal paste powder and the coffee powder alternately enter a feed column from feed inlets of the two feed hoppers respectively, so that the herbal paste powder and the coffee powder in the feed column are distributed in alternate layers along the feed direction, the ratio of the amounts of the herbal paste powder and the coffee powder alternately entering the feed column is the ratio of the amounts of the required herbal paste powder and the coffee powder after mixing, and the amount of one-time feeding of the herbal paste powder is smaller than 1/10 of the total amount of the herbal paste powder; the herbal paste powder and the coffee powder in the feed column alternately fall into a conical filter plate of the premixing tank to be filtered and enter into auger blades below, and the auger blades carry out preliminary mixing and simultaneously convey the powder after preliminary mixing to a drum-type stirring mechanism to carry out final mixing; s4, sealing and packaging the finally mixed composite coffee powder. Further, wherein S1 comprises: S1.1, ultrasonic cleaning, namely placing the carefully selected plant herba
