Description

Technical Field

[0001] This utility model belongs to the technical field of feed fermentation ton bags, specifically a feed fermentation ton bag based on improved air permeability. Background Technology

[0002] Feed fermentation is a key process in modern animal husbandry and feed processing to improve the nutritional value, palatability, and shelf life of feed. Its core principle is to break down the macromolecules in feed raw materials into easily digestible and absorbable small molecule nutrients through the metabolic action of microorganisms (such as lactic acid bacteria and yeast), and to produce organic acids and other substances that inhibit the growth of putrefactive bacteria. In large-scale feed fermentation production, ton bags are the main containers for carrying fermented materials, and their structural design directly affects fermentation efficiency, material quality, and production management costs.

[0003] However, in existing technologies, during large-scale fermentation, materials are prone to clumping due to gravity compaction and localized accumulation of moisture and heat. Existing ton bags lack anti-caking design, resulting in uneven fermentation and easy blockage during unloading. In addition, the inner wall of the bag is severely adhered to the material, resulting in a high unloading residue rate, which increases cleaning difficulty and material loss.

[0004] Traditional ton bags are mostly single-layer structures, which cannot buffer external temperature fluctuations. High temperatures in summer can easily cause the temperature inside the bag to exceed the tolerance threshold of microorganisms, while low temperatures in winter can cause fermentation to stop, affecting fermentation stability. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a feed fermentation ton bag based on improved air permeability, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feed fermentation ton bag based on improved air permeability, comprising a fermentation ton bag body, with multiple sets of handles fixedly connected to the outer side of the fermentation ton bag body in a symmetrical structure, a bag opening at the top of the fermentation ton bag body, multiple sets of separating mesh belts fixedly connected inside the fermentation ton bag body, multiple sets of exhaust ports connected to both sides of the fermentation ton bag body, a filter block threadedly connected to the inner side of the exhaust port, and a flow guide liner bag provided inside the fermentation ton bag body.

[0007] As a further embodiment of this utility model: the exhaust ports are distributed at equal intervals along the height direction of the fermentation ton bag body.

[0008] As a further embodiment of this utility model: the filter block includes an outer dustproof mesh, a middle activated carbon filter layer, and an inner one-way breathable membrane.

[0009] As a further embodiment of this utility model: the separating mesh belt includes a transverse separating mesh and a longitudinal separating mesh, wherein the transverse separating mesh and the longitudinal separating mesh are arranged perpendicularly to each other.

[0010] As a further embodiment of this utility model: the flow guide liner is made of food-grade PE material, and its surface is provided with a smooth coating. The edge of the flow guide liner is detachably connected to the inner wall of the fermentation ton bag body by Velcro.

[0011] As a further embodiment of this utility model: a tightening structure is provided at the bag opening, the tightening structure including a drawstring and an adjusting buckle.

[0012] As a further embodiment of this utility model: the main body of the fermentation ton bag adopts a double-layer composite structure, the inner layer is PP woven fabric, the outer layer is wear-resistant fabric coated with aluminum foil, and a breathable cotton interlayer is provided between the two layers.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention allows feed ingredients to be loaded into the top bag opening. Symmetrically distributed handles facilitate mechanical lifting or manual handling, ensuring balanced force distribution and preventing tipping during transportation. After the feed is loaded, a separating mesh belt divides it into multiple independent spaces, reducing local compaction and clumping caused by large-scale accumulation. It also provides channels for the flow of gas and heat within the bag. During fermentation, gases produced by microbial metabolism are discharged through multiple sets of exhaust ports on both sides, preventing excessive pressure inside the bag. The filter blocks inside the exhaust ports block external dust and impurities from entering, while preventing moisture from seeping back into the bag, ensuring a stable fermentation environment. After fermentation, the smooth surface of the inner guide liner reduces feed adhesion, facilitating quick unloading. The overall structure integrates functions such as convenient loading and unloading, anti-caking, directional ventilation, and anti-pollution, improving the uniformity and success rate of feed fermentation while reducing management difficulty and material loss in large-scale operations.

[0015] This invention features a drawstring-adjustable bag opening that allows for flexible control of oxygen intake to adapt to different fermentation stages. After fermentation, a flow-guiding liner made of food-grade PE material with a smooth coating reduces feed adhesion. Its detachable connection to the inner wall of the ton bag via Velcro facilitates individual disassembly for cleaning or replacement, enabling rapid unloading. The overall structure balances ease of loading and unloading, fermentation environment stability, anti-caking, anti-contamination, and temperature adaptability, thereby improving feed fermentation efficiency and quality while reducing large-scale management costs.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] The feed fermentation ton bag based on improved air permeability includes a fermentation ton bag body 1, with multiple sets of handles 2 fixedly connected to the outside of the fermentation ton bag body 1 in a symmetrical structure, a bag opening 3 at the top of the fermentation ton bag body 1, multiple sets of separating mesh belts 5 fixedly connected inside the fermentation ton bag body 1, multiple sets of exhaust ports 4 connected to both sides of the fermentation ton bag body 1, filter blocks 6 threadedly connected to the inside of the exhaust ports 4, and a flow guide liner 7 provided inside the fermentation ton bag body 1.

[0025] In use, feed ingredients are loaded through the top bag opening 3. Symmetrically distributed handles 2 facilitate mechanical lifting or manual handling, ensuring balanced force distribution and preventing tipping during transportation. After the feed is loaded, the separating mesh belt 5 divides it into multiple independent spaces, reducing local compaction and clumping caused by large-scale accumulation, while providing channels for gas and heat flow inside the bag. During fermentation, gases produced by microbial metabolism are discharged through multiple sets of exhaust ports 4 on both sides, preventing excessive pressure inside the bag. The filter block 6 inside the exhaust port 4 can block external dust and impurities from entering, while preventing moisture from seeping back into the bag, ensuring a stable fermentation environment. After fermentation, the inner guide liner 7, with its smooth surface, reduces feed adhesion and facilitates quick unloading. The overall structure integrates functions such as convenient loading and unloading, anti-caking, directional ventilation, and anti-pollution, which not only improves the uniformity and success rate of feed fermentation, but also reduces the management difficulty and material loss in large-scale operations.

[0026] participate Figures 1 to 5The exhaust ports 4 are evenly distributed along the height of the fermentation ton bag body 1. The filter block 6 includes an outer dustproof net, a middle activated carbon filter layer and an inner one-way breathable membrane. The separator mesh belt 5 includes a transverse separator mesh and a longitudinal separator mesh, which are arranged perpendicularly to each other. The guide liner 7 is made of food-grade PE material with a smooth coating on its surface. The edge of the guide liner 7 is detachably connected to the inner wall of the fermentation ton bag body 1 by Velcro. The bag opening 3 is equipped with a tightening structure, which includes a drawstring and an adjustment buckle. The fermentation ton bag body 1 adopts a double-layer composite structure. The inner layer is PP woven fabric and the outer layer is wear-resistant fabric coated with aluminum foil. A breathable cotton interlayer is set between the two layers.

[0027] Specifically, by adjusting the drawstring and adjusting buckle at the bag opening 3, the bag opening 3 is opened, and the feed raw materials are loaded into the fermentation ton bag body 1, which adopts a double-layer composite structure. The symmetrically distributed handles 2 facilitate mechanical lifting or handling. The loaded feed is divided into multiple independent spaces by the horizontal and vertically intersecting dividing mesh belts 5, which reduce the accumulation, compaction and clumping, while providing channels for gas and heat flow. During fermentation, the gas generated by the feed at different heights is evenly discharged through the exhaust ports 4, which are evenly distributed along the height direction, to avoid local gas accumulation. When venting, the outer dustproof net of the filter block 6 blocks external impurities, and the middle active layer... The activated carbon filter layer adsorbs odors, and the inner one-way breathable membrane prevents outside air and moisture from entering. Combined with the bag opening 3, which can be adjusted by a drawstring, the amount of oxygen entering can be flexibly controlled to adapt to different fermentation stages. After fermentation, the guide bag 7, made of food-grade PE material with a smooth coating, can reduce feed sticking. Its detachable connection to the inner wall of the ton bag body via Velcro makes it easy to disassemble, clean, or replace, facilitating quick unloading. The overall structure takes into account the convenience of loading and unloading, the stability of the fermentation environment, the prevention of clumping, the prevention of pollution, and the temperature adaptability, thereby improving the efficiency and quality of feed fermentation and reducing the cost of large-scale management.

[0028] Working principle of this utility model:

[0029] First, open the bag opening 3 by adjusting the drawstring and adjusting buckle at the bag opening 3, and put the feed raw materials into the fermentation ton bag body 1 with a double-layer composite structure. The symmetrically distributed handles 2 can assist in mechanical hoisting or manual handling, ensuring that the bag body is subjected to balanced force and is not easy to tip over during loading and transportation, laying a stable foundation for subsequent fermentation.

[0030] Secondly, after entering the fermentation stage, the feed is divided into multiple independent spaces by the horizontal and vertically intersecting dividing mesh belts 5. This reduces the clumping caused by material accumulation and compaction, and provides a channel for the flow of gas and heat inside the bag. At the same time, the exhaust ports 4, which are evenly distributed along the height of the ton bag, can evenly discharge the gas generated by the fermentation of materials at different heights, avoiding excessive pressure inside the bag. The filter block 6 inside the exhaust port 4 further ensures a clean and stable fermentation environment inside the bag. In addition, the bag opening 3, which can be adjusted by a drawstring, can also flexibly control the amount of oxygen entering to adapt to the needs of different fermentation stages.

[0031] It is worth mentioning that the design of the diversion liner 7 facilitates unloading and cleaning after fermentation. Its food-grade PE material ensures feed safety, and the smooth surface coating reduces feed adhesion. The detachable connection between the ton bag and the inner wall of the main body via Velcro makes it easy to unload quickly after fermentation, and it can also be disassembled for cleaning or replacement, improving the reusability and cleanliness of the ton bag.

[0032] Finally, through the coordinated work of its components, the overall structure integrates multiple functions such as ease of loading and unloading, stability of the fermentation environment, anti-caking, anti-contamination, and temperature adaptability. While improving the uniformity, efficiency, and quality of feed fermentation, it effectively reduces the management difficulty and material loss in large-scale operations, meeting the actual needs of large-scale feed fermentation.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
