The Venturi tube of Wort oxygenating device
Technical field
The utility model relates to a kind of Venturi tube of Wort oxygenating device.
Background technology
The Wort oxygenating device is a unique important step that needs oxygen in the process for beer production, and what of oxygenation capacity whether evenly will directly influence normally carrying out of beer fermentation.Wort oxygenating device originally is to place a nickel rod or titanium rod in the pipeline of necking down, and pressurized air enters in the wheat juice by nickel rod or titanium rod, thereby reaches the purpose of oxygenation.The shortcoming of this device is: nickel rod or titanium rod is through using the back cracky for a long time, and easy cleaning not, and cost is high and can not satisfy the hygienic requirements of foodstuff production.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and the Venturi tube of a kind of oxygenation convenience, the better Wort oxygenating device of ferment effect is provided.
For achieving the above object, the utility model adopts a kind of Venturi tube of Wort oxygenating device, comprise interconnective successively the ABC of pipeline, the necking down pipeline, the diffusion pipeline, Venturi tube comprises pneumatic head mechanism, pneumatic head mechanism is by the oxygenation cover, the oxygenation joint, the joint circle, the central authorities of oxygenation cover form passage along its center line, the two ends of oxygenation cover respectively with necking down pipeline and diffusion pipe connection, middle position at the outer wall of oxygenation cover forms the annular groove, perisporium one circle that overlaps along its oxygenation at bottom portion of groove is evenly distributed with 8 feeding oxygen holes, the medullary ray of the medullary ray of feeding oxygen hole and oxygenation cover is vertical relation, the joint loop-shaped is an annular, the joint snare is located at the position that oxygenation puts relative groove, form and the corresponding a plurality of through holes of groove on the joint circle, a plurality of oxygenation joint one ends are fixed in this through hole, and the other end forms the oxygen admission port.
The utility model is set up a pneumatic head mechanism between necking down pipeline and diffusion pipeline, the feeding oxygen hole that pressurized air is 2mm by 8 diameters being distributed on oxygenation and putting enters in the wheat juice by the oxygenation cover, make pressurized air in wheat juice, form the dissolving fast of turbulent flow back, reach the needed oxygen level of yeast growth, be 8-12mg/l, also can regulate the oxygen level of wheat juice according to user's requirement, to satisfy zymic normal growth breeding in the fermenting process, guarantee that the yeast quality is to improve quality of beer.And pneumatic head mechanism cost is low, and is not fragile, and it is convenient to clean.
The utility model further is set to connect one section observation pipeline at the other end of diffusion pipeline, observes pipeline and is socketed to form by visor and visor protective sleeve, at visor protective sleeve external fixation hold-down nut is arranged, and the other end of observing pipeline connects a ring flange.
The utility model further is set to be provided with the grommet type seals of many groups again between the outer wall of the inwall of joint circle and oxygenation cover and constitutes the static seal cooperation.

Embodiment
As shown in Figure 1, specific embodiment of the utility model is a kind of Venturi tube of Wort oxygenating device, comprise interconnective successively the ABC of pipeline 1, necking down pipeline 2, diffusion pipeline 3, pneumatic head mechanism 4, pneumatic head mechanism 4 is by oxygenation cover 41, oxygenation joint 42, joint circle 43, the central authorities of oxygenation cover 41 form passage 411 along its center line, the two ends of oxygenation cover 41 are connected with diffusion pipeline 3 with necking down pipeline 2 respectively, middle position at the outer wall of oxygenation cover 41 forms annular groove 412, perisporium one circle in groove 412 bottoms along its oxygenation cover 41 is evenly distributed with 8 feeding oxygen holes 413, the medullary ray of the medullary ray of feeding oxygen hole 413 and oxygenation cover 41 is vertical relation, joint circle 43 is shaped as annular, joint circle 43 is set on the oxygenation cover 41 position of groove 412 relatively, is provided with 2 groups of grommet type sealss 5 and constitutes static seals and cooperate between the outer wall of the inwall of joint circle 43 and oxygenation cover 41.Form with 431,2 oxygenation joint 42 1 ends of groove 412 corresponding 2 through holes on the joint circle 43 and be fixed in this through hole 431 the other end formation oxygen admission port 421.The other end at diffusion pipeline 3 connects one section observation pipeline 6, observes pipeline 6 and is socketed to form by visor 61 and visor protective sleeve 62, at visor protective sleeve 62 external fixation hold-down nut 63 is arranged, and the other end of observing pipeline 6 connects a ring flange 7.
The utility model oxygenation process: the feeding oxygen hole 413 that pressurized air is 2mm by 8 diameters being distributed on the oxygenation cover 41 enters in the wheat juice by the oxygenation cover, make pressurized air in wheat juice, form the dissolving fast of turbulent flow back, reach the needed oxygen level of yeast growth, be 8-12mg/l, also can regulate the oxygen level of wheat juice according to user's requirement, to satisfy zymic normal growth breeding in the fermenting process, guarantee that the yeast quality is to improve quality of beer.
