Description

Technical Field

[0001] The present invention relates to the technical field of liquid microbial microbial inoculant storage devices, and in particular to a device for storing liquid microbial inoculants. Background Art

[0002] In the prior art, the storage method of liquid microbial agents has the following problems:

[0003] 1. The packaging barrels of liquid microbial inoculants are generally not sterilized, because most of them cannot withstand high temperatures and cannot be sterilized at high temperatures. If the packaging barrels are sterilized by chemical or irradiation methods, the sterilization cost will be too high.

[0004] 2. Generally, liquid microbial agents are contained in wide-mouthed containers such as stacking barrels. The bacteria are easy to grow on the surface of the liquid to form a biofilm, which affects the appearance. The surface is also easily contaminated by miscellaneous bacteria, especially fungal contamination, which will seriously affect the quality.

[0005] 3. Preventing bacterial contamination by adding sodium benzoate, glycine, potassium sorbate, etc. has certain limitations. This method can only be used for Bacillus liquid microbial agents. Appropriate amounts of preservatives such as sodium benzoate, glycine, potassium sorbate, etc. will not kill spores. However, this method cannot prevent bacterial contamination of non-Bacillus liquid microbial agents. Adding sodium benzoate, glycine, potassium sorbate, etc. will inhibit the liquid microbial agent itself, resulting in a decrease in the number of effective live bacteria.

[0006] 4. The method of introducing nitrogen to seal can reduce the respiration of liquid microbial agents. This method is only suitable for the preservation of strictly aerobic liquid microbial agents and cannot solve the gas production problem of facultative anaerobic liquid microbial agents.

[0007] 5. Under the current packaging conditions, the liquid microbial agent itself or the isolation layer on the surface will form a "water film or oil film" on the surface of the breathable membrane. In addition, the bacterial film formed by the contamination of miscellaneous bacteria will also cover the breathable film, resulting in poor ventilation. Summary of the invention

[0008] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a device for storing liquid microbial agents, which is used to solve the problems of packaging bloating and liquid microbial agent contamination in the prior art. The structural design of the present invention is reasonable and practical, simple and efficient, low-cost, and does not require anti-pollution formula treatment for the liquid microbial agent itself, which can extend the shelf life of the liquid microbial agent and facilitate its promotion and use.

[0009] To achieve the above-mentioned and other related purposes, the present invention provides a device for storing liquid microbial inoculants, the device for storing liquid microbial inoculants comprising:

[0010] A storage shell, wherein an isolation layer is disposed in the storage shell; and an opening is disposed on the top of the storage shell;

[0011] The anti-blocking and breathable device comprises a breathable membrane, a buffer cavity and a reverse funnel from top to bottom, the bottom of the reverse funnel is connected to the opening of the storage shell, the buffer cavity is connected to the reverse funnel through a buffer port, and a boss is provided on the inner wall of the buffer port.

[0012] By designing the isolation layer to float above the liquid microbial agent, the substances in the isolation layer do not inhibit the liquid microbial agent itself, thus avoiding contamination by surface bacteria, especially fungi. There is no need to sterilize the packaging barrel, package under strict aseptic conditions, or prepare the liquid microbial agent itself to prevent contamination and inhibit activity. The anti-blocking breathable device effectively prevents the vibration during transportation from covering and blocking the breathable membrane with the liquid microbial agent or the isolation layer, thereby causing flatulence. After the liquid enters the buffer chamber, it can quickly flow back downward, reducing the probability of the liquid microbial agent itself and the surface isolation layer covering the breathable membrane, which is conducive to the rapid discharge of gas.

[0013] Furthermore: the lower part of the storage shell is cylindrical, and the upper part of the storage shell is conical.

[0014] The tapered structure with a small top and a large bottom physically reduces the contact area between the liquid microbial agent and the air, and reduces the amount of the isolation layer on the surface of the liquid microbial agent in the container and the probability of contamination.

[0015] Furthermore, the lower part of the storage shell is cylindrical, and the upper part of the storage shell is provided with an inclined side plate. The tapered structure with a small top and a large bottom physically reduces the contact area between the liquid microbial agent and the air, and reduces the amount of the isolation layer on the surface of the liquid microbial agent in the container and the probability of contamination.

[0016] Further: a handle is provided on the upper part of the storage housing. The handle is provided to facilitate lifting

[0017] Furthermore: a liquid microbial inoculant is installed in the cavity of the storage shell, and the isolation layer covers the liquid microbial inoculant.

[0018] The liquid microbial inoculant is stored in the container body and sealed with an isolation layer.

[0019] Furthermore: the isolation layer is a mixture of a water-insoluble preservative and a non-volatile oil after homogenization and emulsification; the water-insoluble preservative is one or at least one of sorbic acid, benzoic acid, and methyl paraben; the non-volatile oil is one or at least one of a vegetable oil and paraffin oil having a density less than water.

[0020] The isolation layer is a homogeneous emulsion formed by one or a combination of water-insoluble preservatives, vegetable oil, and paraffin oil. It can isolate liquid microbial agents from the air, protect the microbial agents from being killed by preservatives and maintain a low metabolic rate, which is beneficial to extending the shelf life of the microbial agents. In addition, the isolation layer can greatly reduce the amount of preservatives used.

[0021] Furthermore: the mass ratio of the water-insoluble preservative to the non-volatile oil in the isolation layer is (0.06-0.5):100; the thickness of the isolation layer is ≤1 mm.

[0022] Furthermore: buffer beads are installed on the boss.

[0023] The inner wall of the buffer port is provided with a boss, on which freely movable buffer beads are placed. After the liquid enters the buffer cavity, it quickly flows back downward through the groove channel between the two bosses, reducing the probability of the bacterial agent itself and the surface isolation layer covering the breathable membrane, which is conducive to the rapid discharge of gas.

[0024] Further, the breathable membrane is a hydrophobic and oleophobic microporous leakproof breathable membrane, which can prevent a small amount of liquid and oil that enters the buffer cavity under severe shock conditions from covering the breathable membrane and affecting the breathability.

[0025] As described above, a device for storing liquid microbial agents of the present invention has the following beneficial effects: by designing the isolation layer to float above the liquid microbial agent, the substances in the isolation layer do not inhibit the liquid microbial agent itself, thus avoiding contamination by surface bacteria, especially fungi. There is no need to sterilize the packaging barrel, there is no need to package under strict aseptic conditions, and there is no need to prepare the liquid microbial agent itself for pollution prevention and activity inhibition. The anti-blocking breathable device effectively prevents vibrations during transportation from covering and blocking the breathable membrane with the liquid microbial agent or the isolation layer, thereby causing flatulence. After the liquid enters the buffer chamber, it can quickly flow back downward, reducing the probability of the liquid microbial agent itself and the surface isolation layer covering the breathable membrane, which is conducive to the rapid discharge of gas.
