Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, and more specifically to a milk production fermentation tank. Background Art

[0002] A fermentation tank for milk beverage production is a device used for microbial fermentation in the production and processing of milk beverages, and has been widely used in the field of beverage processing; existing fermentation tanks for milk beverage production include vertical fermentation tanks and horizontal fermentation tanks, among which the vertical fermentation tank has the advantages of small footprint, simple structure, easy maintenance, etc. However, due to the influence of gravity during the fermentation process of the vertical fermentation tank, the gas concentration at the top of the fermentation product will be lower than that at the bottom, which is not conducive to the optimization of the fermentation effect. At the same time, a certain amount of sterile oxygen will remain on the top of the fermentation tank. When ventilation is performed, the sterile oxygen on the top will be wasted, which is inconvenient for staff to use. Utility Model Content

[0003] In order to overcome the above defects of the prior art, the utility model provides a milk production fermentation tank to solve the problems existing in the above background technology.

[0004] The utility model provides the following technical solutions: a milk production fermentation tank, comprising a fermentation tank, a booster device is provided on the top of the fermentation tank, a feed port is provided inside the booster device, a protective bottom plate is provided at the bottom of the feed port, a No. 1 ventilation port is provided on the top of the booster device, a No. 2 ventilation port located on one side of the No. 1 ventilation port is provided on the top of the booster device, a partition located above the protective bottom plate is provided on the outside of the feed port, a booster fan is provided on the inside of the booster device, a top guide plate is provided at the bottom of the outer side of the booster device, a ventilation steel pipe is provided on the outside of the top guide plate, part of the oxygen and other gases remaining on the top of the fermentation tank are blown to the ventilation steel pipe through the booster fan, and then refluxed to the bottom of the fermentation tank through the ventilation steel pipe, and mixed with milk for fermentation again, so that the fermentation is more thorough, and at the same time, the utilization rate of oxygen and other gases on the top is increased, thereby reducing the ventilation frequency in the fermentation tank, thereby reducing the fermentation cost of milk;

[0005] Furthermore, an underwater bubbler is provided at one end of the ventilation steel pipe, and air is supplied to the underwater bubbler through the ventilation steel pipe, and the underwater bubbler bubbles the supplied gas. The bubbles will stir the inside of the milk, so that the milk and microorganisms are mixed more thoroughly, thereby accelerating the fermentation efficiency of the milk.

[0006] Furthermore, the number of the ventilation steel pipes is eight, and the eight ventilation steel pipes are evenly distributed inside the fermentation tank. The eight ventilation steel pipes are used to supply air to the underwater bubbler at the same time, so that the underwater bubbler can bubble evenly and stably, thereby increasing the working stability of the underwater bubbler.

[0007] Furthermore, the protective bottom plate and the boost fan are uniformly semicircular in shape, and a filter groove is provided around the bottom of the protective bottom plate. The protective bottom plate and the top guide plate are both semicircular, so that the water in the water bubbles will flow back into the fermentation tank along the bend. At the same time, the filter groove will discharge the moisture remaining on the inner side of the protective bottom plate into the fermentation tank, and the wind direction of the boost fan is outward, which prevents the water in the bubbles from exploding toward the boost fan, thereby increasing the safety of the boost fan.

[0008] Furthermore, a discharge port is provided at the bottom of the fermentation tank, and a support frame is provided around the bottom of the fermentation tank and is located outside the discharge port. The fermentation tank is supported by the support frame, and the fermented milk in the fermentation tank is discharged through the discharge port for storage and transportation.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the booster fan blows part of the oxygen and other gases remaining on the top of the fermentation tank to the ventilation steel pipe, and then makes them flow back to the bottom of the fermentation tank through the ventilation steel pipe, and re-mixes and ferments with the milk, making the fermentation more thorough, while increasing the utilization rate of oxygen and other gases on the top, thereby reducing the ventilation frequency in the fermentation tank, thereby reducing the fermentation cost of milk.

DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The milk production fermentation tank involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0016] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0017] Embodiment 1

[0018] Reference Figure 1-4 , a milk production fermentation tank, first install the protective bottom plate 5 at the bottom of the feed port 4, then install the partition 11 above the protective bottom plate 5 outside the feed port 4, then install the booster 6 above the partition 11 outside the feed port 4, and then install the booster fan 9 above the partition 11 inside the booster 6, then install the top guide plate 10 on the outside of the bottom of the booster 6, then install the No. 1 ventilation port 7 on the top of the booster 6, and then install the No. 2 ventilation port 8 on one side of the No. 1 ventilation port 7 on the top of the booster 6, then surround the ventilation steel pipe 12 and install it on the outside of the booster 6, and align the air inlet of the ventilation steel pipe 12 with the booster fan 9 one by one, then install the underwater bubbler 13 at one end of the bottom of the ventilation steel pipe 12, then install the feed port 4 inside the fermenter 1, then install the discharge port 2 at the bottom of the fermenter 1, and finally install the support frame 3 around the bottom of the fermenter 1, and open a filter tank 14 around the bottom of the protective bottom plate 5.

[0019] The working principle of the utility model is as follows: the staff connects the feed pipe with the feed port 4, and then connects the ventilation tank with the No. 1 ventilation port 7 and the No. 2 ventilation port 8 respectively. At this time, milk and trace elements are added to the fermentation tank 1 for fermentation treatment. After fermentation for a period of time, a large amount of gas produced by fermentation will exist on the top of the fermentation tank 1. At this time, the booster device 6 and the booster fan 9 are started, and then the booster fan 9 blows the gas produced by fermentation into the ventilation steel pipe 12, and enters the underwater bubbler 13 along the ventilation steel pipe 12, thereby supplying air to the underwater bubbler 13, causing the underwater bubbler 13 to start bubbling, so that the oxygen remaining on the top of the fermentation tank 1 continues to ferment the milk in the fermentation tank 1, thereby increasing the oxygen utilization rate on the top; at the same time, when the milk is fermenting, the booster fan 9 continuously supplies the gas. The gas at the top of the inner wall of the fermentation tank 1 is continuously caused to flow to the underwater bubbler 13 through the ventilation steel pipe 12. The bubbles bubbling from the underwater bubbler 13 will stir the inside of the milk, so that the milk and the microorganisms are mixed more thoroughly, thereby accelerating the fermentation efficiency of the milk. When the underwater bubbler 13 bubbles and stirs the fermentation tank 1, a part of water will remain in the rising bubbles. Some of the water-containing bubbles touch the bottom of the protective bottom plate 5 and explode there, while the remaining part of the water-containing bubbles touch the bottom of the top guide plate 10 and explode. Since the protective bottom plate 5 and the top guide plate 10 are both semicircular, the water in the bubbles will flow back into the fermentation tank 1 along the bend. At the same time, the wind direction of the booster fan 9 is outward, which prevents the water in the bubbles from exploding toward the booster fan 9, thereby increasing the safety of the booster fan 9.

[0020] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
