Description

Technical Field

[0001] This utility model relates to the field of yeast preservation technology, specifically a packaging device for preserving highly active fresh yeast. Background Technology

[0002] Fresh yeast, as an active biological agent, has a wide range of applications in food fermentation, brewing and other fields.

[0003] Currently, most common fresh yeast preservation packaging methods on the market are simple airtight packaging. While these can isolate external contaminants to some extent, they are not very effective at controlling humidity and oxygen levels. Excessive humidity can easily lead to bacterial growth in the yeast, while excessively low humidity will cause the yeast to dry out and become inactive. Simultaneously, yeast needs a suitable amount of oxygen for respiration during storage to maintain its activity, but the oxygen content and impurities in the outside air are difficult to control precisely. Furthermore, fresh yeast is prone to sedimentation during storage, resulting in uneven yeast distribution and affecting its effectiveness. Therefore, a high-activity fresh yeast preservation packaging device is proposed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-activity fresh yeast preservation packaging device, which has advantages such as optimized humidity control and prevention of yeast sedimentation, thus solving problems such as poor humidity control and easy yeast sedimentation in existing packaging.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A highly active fresh yeast preservation packaging device includes a box body and a box lid. A nanoporous silicone membrane is fixedly connected to the inner side of the box body, and a hydrophobic and breathable PE membrane is fixedly connected to the outer side of the box body. A sealing ring is fixedly connected to the bottom of the box lid, and a stirring component to prevent yeast sedimentation is provided on the top of the box lid.

[0007] The stirring assembly includes a housing fixedly connected to the top of the box cover, a motor fixedly connected to the inner side of the housing, an installation shaft fixedly connected to the output shaft of the motor, an installation plate fixedly connected to the bottom end of the installation shaft, a stirring shaft provided at the bottom of the installation plate, a stirring paddle fixedly connected to the outer side of the stirring shaft, and an installation cylinder provided at the bottom end of the stirring shaft.

[0008] Furthermore, the outer wall of the stirring shaft is square, the bottom of the mounting plate has a first slot adapted to the stirring shaft, and the top of the mounting cylinder has a second slot adapted to the stirring shaft.

[0009] Furthermore, the bottom end of the mounting shaft passes through the top and bottom of the box cover in sequence and extends to the inside of the sealing ring opening to be fixedly connected to the mounting plate, and the mounting cylinder is rotatably connected to the inner bottom wall of the box body.

[0010] Furthermore, the surface of the box body is provided with through holes, which are located between the nanoporous silicone membrane and the hydrophobic and breathable PE membrane.

[0011] Furthermore, the number of stirring paddles is six, and the six stirring paddles are arranged equidistantly along the vertical direction of the stirring shaft.

[0012] Furthermore, a base plate is fixedly connected to the bottom of the box body, and connecting plates are fixedly connected to the left and right sides of the top of the base plate. A connection port is opened on the inner side of the connecting plate, and a positioning block is provided on the inner side of the connection port.

[0013] Furthermore, the left and right side walls of the box cover are provided with positioning grooves that are adapted to the positioning blocks, and the inner side of the positioning grooves is fixedly connected with magnetic blocks that are adapted to the positioning blocks.

[0014] Compared with the prior art, this utility model provides a highly active fresh yeast preservation packaging device, which has the following beneficial effects:

[0015] This highly active fresh yeast preservation packaging device uses a nanoporous silicone membrane to precisely absorb and release moisture, maintaining a suitable humidity environment inside the box. When the humidity is too high, the nanoporous silicone membrane absorbs excess moisture; when the humidity is too low, it releases the stored moisture, effectively preventing the yeast from spoiling due to unsuitable humidity and ensuring the yeast's activity. At the same time, the hydrophobic and breathable PE membrane allows external oxygen to enter the box while expelling carbon dioxide produced by yeast respiration, maintaining a stable respiration environment for the yeast. This design ensures the yeast's oxygen supply while avoiding the inhibition of yeast activity by carbon dioxide accumulation, thus extending the yeast's shelf life. In addition, the stirring component uses a motor to drive the stirring shaft and stirring paddle to rotate, continuously stirring the yeast and preventing it from settling and clumping during storage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 The high-activity fresh yeast preservation packaging device in this embodiment includes a box body 1 and a box lid 2. A nanoporous silicone membrane 3 is fixedly connected to the inner side of the box body 1, and a hydrophobic and breathable PE membrane 4 is fixedly connected to the outer side of the box body 1. A sealing ring 5 is fixedly connected to the bottom of the box lid 2, and a stirring component to prevent yeast sedimentation is provided on the top of the box lid 2.

[0022] Please see Figure 1 In this embodiment, the stirring assembly includes a housing 6 fixedly connected to the top of the box cover 2, a motor 7 fixedly connected to the inner side of the housing 6, an installation shaft 8 fixedly connected to the output shaft of the motor 7, an installation plate 9 fixedly connected to the bottom end of the installation shaft 8, a stirring shaft 10 provided at the bottom of the installation plate 9, a stirring paddle 11 fixedly connected to the outer side of the stirring shaft 10, and an installation cylinder 12 provided at the bottom end of the stirring shaft 10.

[0023] Specifically, the outer wall of the stirring shaft 10 is square, the bottom of the mounting plate 9 is provided with a first slot that is compatible with the stirring shaft 10, and the top of the mounting cylinder 12 is provided with a second slot that is compatible with the stirring shaft 10.

[0024] It should be noted that this design allows the stirring shaft 10 to be precisely inserted into the mounting plate 9 and the mounting cylinder 12, achieving a stable connection. Compared to a round shape, the square design can better transmit torque during rotation, preventing the stirring shaft 10 from slipping during rotation and ensuring that the stirring assembly can operate stably and efficiently. Furthermore, this design allows the stirring shaft 10 and the stirring paddle 11 to be quickly removed from the stirring assembly for replacement or cleaning.

[0025] Specifically, the bottom end of the mounting shaft 8 passes through the top and bottom of the cover 2 in sequence and extends to the inside of the sealing ring 5 and is fixedly connected to the mounting plate 9. The mounting cylinder 12 is rotatably connected to the inner bottom wall of the box body 1.

[0026] Specifically, the surface of the box 1 is provided with through holes, which are located between the nanoporous silicone membrane 3 and the hydrophobic and breathable PE membrane 4.

[0027] It should be noted that the through-holes are located between the nanoporous silicone membrane 3 and the hydrophobic and breathable PE membrane 4, forming a gas exchange channel. The nanoporous silicone membrane 3 regulates humidity, while the hydrophobic and breathable PE membrane 4 allows oxygen to enter and carbon dioxide to be discharged, maintaining the respiration environment for yeast.

[0028] Specifically, there are six agitators 11, and the six agitators 11 are arranged equidistantly along the vertical direction of the agitator shaft 10.

[0029] Specifically, a base plate 101 is fixedly connected to the bottom of the box body 1, and a connecting plate 13 is fixedly connected to the left and right sides of the top of the base plate 101. A connection port is opened on the inner side of the connecting plate 13, and a positioning block 14 is provided on the inner side of the connection port. Positioning grooves that are compatible with the positioning block 14 are opened on the left and right side walls of the box cover 2, and a magnetic block 15 that is compatible with the positioning block 14 is fixedly connected to the inner side of the positioning groove.

[0030] It should be noted that after the positioning block 14 is inserted into the positioning groove of the lid 2, the connection between the connecting plate 13 and the lid 2 is realized, thereby realizing the connection between the box body 1 and the lid 2. Furthermore, the magnetic block 15 is fixed in the positioning groove and magnetically fixed with the positioning block 14, which improves the connection reliability between the lid 2 and the box body 1 and prevents the lid 2 from being accidentally opened during transportation or storage.

[0031] The working principle of the above embodiments is as follows:

[0032] Place fresh yeast into the box 1 and close the lid 2. The sealing ring 5 at the bottom of the lid 2 fits tightly against the top of the box 1, forming a relatively sealed environment. At this time, the nanoporous silicone membrane 3 absorbs excess moisture in the box 1, maintains humidity balance, and prevents the yeast from spoiling due to excessive or insufficient humidity. Meanwhile, the hydrophobic and breathable PE membrane 4 allows external oxygen to enter the box 1 and removes carbon dioxide produced by yeast respiration, ensuring that yeast respiration proceeds normally.

[0033] Start motor 7, which drives the mounting shaft 8 to rotate. The mounting shaft 8 then drives the mounting plate 9 to rotate. The stirring shaft 10 at the bottom of the mounting plate 9 rotates synchronously with the mounting plate 9. The stirring paddle 11 on the stirring shaft 10 also rotates, which fully stirs the yeast and prevents the yeast from settling and clumping.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0035] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
