Technical Field

The invention relates to the field of beer selling machines, in particular to a straight-through faucet with a pneumatic diaphragm controlling residue discharge function and a working method thereof.

Background

The traditional beer selling modes are generally divided into two modes, one mode is to sell the beer in a bottle, namely, the weighed beer is filled into a wine bottle; the other is sold in bulk. Among them, bulk selling has an advantage of selling beer according to the actual needs of buyers, and beer dispensers are very popular in the market in order to overcome the problem of manpower waste caused by the need of both buyers and sellers on the spot for selling bulk beer. The prior beer selling machine has the following problems:

1. the beer discharged from a wine outlet tap is easy to cause the mixing of multi-taste beer;

in the most extensive prior art, a single wine barrel is provided with a wine outlet tap, so that a large number of wine outlet taps are needed when selling various tastes or brands of wine, and a waiter is required to select a target tap and manually play the wine when playing the wine. The applicant has applied a multi-way dispenser by which a plurality of wines can be dispensed from a single tap, but if only one tap is used, the dispensing of beer from a single tap tends to result in a mix of multi-flavored beers.

2. The beer is easy to generate foam when being discharged.

Beer dispensing is a complex problem, and the effects of temperature or pressure can cause a large amount of foam during beer dispensing, resulting in failure of the beer dispensing. In industrial equipment, in order to avoid a large amount of foam generated by wine, methods with relatively complex processes such as isobaric filling and the like are often adopted to solve the problem of wine foam. Nowadays, a refrigeration coil is used in some simple beer machines, and one section of coil corresponds to one beer outlet tap to realize that a beer outlet pipeline is filled with beer, so that the problem of beer foam can be solved.

3. The wine pipeline is easy to be blocked and the microorganism is easy to remain.

Because beer contains microorganisms such as yeast, a large amount of bacteria can be bred if the beer outlet pipeline is not cleaned frequently, and the pipeline can be blocked after the beer is sticky. The piping therefore needs to be cleaned frequently to ensure hygiene. Generally, pipeline cleaning requires a plurality of faucets to be manually opened by an attendant to achieve smooth cleaning of the faucets.
