Abstract

COa leakage to 0- air and return free penetrating air into the vessel performs ball-bearing a closure that is made of loose the moving body in a vertical direction and close to the tapered flat tube.

Description

(54) Ferment tube with ball valve

The leakage of the CO 2 fermentation gases into the air and the free return of air into the vessel is accomplished by a ball closure which is formed from a free-moving cap body in a vertical direction and lying tightly on the tapered flat tubes.

FIG

The invention relates to a fermentation tube in which the leakage of CO2 fermentation gases and the prevention of air ingress into the fermentation vessel is controlled by a ball valve.

At present, glass fermenting tubes are used, which are quite complex in shape. The gaseous fermentation products are discharged through a water column that appears to prevent air from entering the fermentation vessel. If the fermentation is already complete, the air is passed through the water into the fermentation vessel by means of external cooling until the pressures are equalized.

SUMMARY OF THE INVENTION The invention is based on the fact that, in a vertical part, at one point of the tapered tube, there is a sealing body such as a ball (or elongated cone rotating surface) which prevents free air flow into the interior of the fermentation vessel. When the gaseous fermentation products reach the pressure required in the container to lift the stopper, they will spontaneously escape into the atmosphere.

The advantage of this solution is the simplification of the shape of the fermentation tube. The sealing element in the tube better prevents the ingress of air during fermentation into the fermentation vessel. A minor advantage is that it is not necessary to pour water into the fermentation tube according to the invention.

Figure 1 shows a fermentation tube with a ball cap.

The ball-shaped fermentation tube is preferably made of a glass tube of circular cross-section or other transparent plastic. The shape of the closure member 1 is preferably a ball or a truncated rotary cone. The maximum diameter of the closing body w is smaller than the inner diameter of the fermentation tube part 4. The weight of the stopper should not produce more force than is necessary to blow out a water column several centimeters tall in the old type of fermentation tubes. Suitably, a soft plastic material has been applied to the flat glass sealing tube contact body or the entire sealing body is made of rubber. The tapered bend 2 of the tube retains the closure member. The contact surface between the closure member and the tube must be impermeable from the end of the air tube 4 and, on the other hand, a small overpressure of gas must lift the closure member. At the top of the tube 5 is a constriction to prevent the closure body from falling freely. It is desirable to bend the top of the tube to prevent dust from falling freely inside the tube. The diameters of the fermentation tube part 4, 5 need not be the same.

The ball-end fermentation tube can be placed in a stopper and used in the production of fermented beverages in households.
