Abstract

The utility model provides a special packaging bag for fermented feed, which comprises a bag, wherein the upper part of the bag is provided with a sealing element, and the bag is provided with an exhaust one-way valve for exhausting outwards and an air inlet one-way valve for feeding air inwards; the number of the exhaust check valves and the number of the intake check valves are both more than or equal to 1; the exhaust check valve and the air inlet check valve are fixedly connected with the bag through heating fusion. And filter cotton is arranged in the exhaust one-way valve and the air inlet one-way valve. The utility model discloses set up the check valve that can exhaust and can admit air simultaneously on the wrapping bag, can realize that the earlier stage of fermentation exhausts through outside carminative pneumatic valve on the sack, has waited the after-fermentation stage, when beginning to breathe in, admits air toward the sack through the pneumatic valve of the reverse installation of second to guaranteed the after-fermentation stage, the sack can not be inhaled into the vacuum form by living fungus, and the fermented fodder does not agglomerate, ensures the convenience that raiser used fermented fodder.

Description

Special packaging bag for fermented feed

Technical Field

The utility model relates to the technical field of packaging bags, in particular to a packaging bag special for fermented feed.

Background

In recent years, fermented feed is rapidly developed in China, and is favored by more and more feed enterprises and breeding friends by virtue of the advantages of easy digestion, growth promotion, green health and the like. However, unlike conventional feeds, fermented feeds contain high water content and contain various viable probiotics and various enzyme preparations. The packaging of fermented feed is completely different from conventional feed. Because the fermented feed can generate some gas in the fermentation stage, the bag for containing the fermented feed is provided with the gas valve which can realize one-way exhaust, and when the plastic bag is produced, the one-way gas-leaking gas valve is arranged at a certain position of the plastic bag to realize the exhaust function, thereby ensuring that the bag is not broken by expansion. Almost all fermented feeds at present are packaged by adopting the bag with the one-way exhaust valve. However, the whole fermentation process is not full-process exhaust, and at the post-fermentation stage, the live probiotics begin to suck air to automatically suck the bag into a vacuum state, the vacuum degree is very high, the fermented feed is greatly extruded, and the fermented feed contains high moisture, so that the final material is seriously extruded and agglomerated, and the use convenience of farmers is seriously affected. The one-way exhaust valve can only exhaust to one side, but can not exhaust in two directions, but if the two-way vent valve is adopted, the fermented feed is always mildewed and goes bad.

SUMMERY OF THE UTILITY MODEL

The utility model provides a special wrapping bag of fermented feed has solved the easy caking of fermented material, the inconvenient shortcoming of use in the distribution feed wrapping bag among the background art.

The technical scheme of the utility model is realized like this: a special packaging bag for fermented feed comprises a bag, wherein a sealing element is arranged at the upper part of the bag, and an exhaust one-way valve for exhausting outwards and an air inlet one-way valve for feeding air inwards are arranged on the bag;

preferably, the number of the exhaust check valves and the number of the intake check valves are both more than or equal to 1;

preferably, the exhaust check valve and the air inlet check valve are fixedly connected with the bag through heating fusion.

Preferably, the exhaust check valve and the air inlet check valve are both internally provided with filter cotton.

The utility model has the advantages that: the utility model discloses set up the check valve that can exhaust and can admit air simultaneously on the wrapping bag, can realize that the earlier stage of fermentation exhausts through outside carminative pneumatic valve on the sack, has waited the after-fermentation stage, when beginning to breathe in, admits air toward the sack through the pneumatic valve of the reverse installation of second to guaranteed the after-fermentation stage, the sack can not be inhaled into the vacuum form by living fungus, and the fermented fodder does not agglomerate, ensures the convenience that raiser used fermented fodder.

Description of the parts: 1. bag, 2, sealing element, 3, exhaust check valve, 4 and air inlet check valve.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The utility model provides a special wrapping bag of fermented feed, includes sack 1, and sack 1 upper portion is equipped with sealing member 2, is equipped with an exhaust check valve 3 of outside exhaust and an air intake check valve 4 of inside air intake on sack 1, all is equipped with the filter pulp in exhaust check valve 3 and the air intake check valve 4, and two check valves are fixed on sack 1 through heating fusion. The mounting positions of the two check valves are not limited. The bag 1 is made of PE, the single-layer thickness of the bag is 10 threads, and the volume specification of the bag is 40 kg. According to different stages of the fermentation process, in the early fermentation stage, the fermented feed is in the gas production stage. In the post-fermentation stage, the fermented feed is aspirated. The air is exhausted through the air exhaust one-way valve 3 on the bag in the early stage of fermentation. When the post-fermentation stage is reached and air begins to be sucked, air can be sucked into the bag through the second air inlet one-way valve 4 which is reversely installed, so that the post-fermentation stage is ensured, the bag cannot be sucked into a vacuum state by probiotics, fermented feed is not caked, and convenience for breeding friends to use the fermented feed is ensured.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
