Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the fermentation apparatus 10 includes: a pouch-shaped device 12, the pouch-shaped device 12 may be woven of a watertight material. More than one strap 14 may be sewn to the pocket 12 at the mouth, 4 straps being shown in fig. 1, or a conventional two-angle strap may be used. Harness 14 may be used to hang bag-shaped device 12 on a mobile machine for ease of handling. A hose 16 is positioned at a corner of bag-shaped device 12, and hose 16 extends from the mouth of the bag to the bottom of the bag, and then a microporous aerator tube 20 is connected by a hose clamp 18. The tube 20 is coiled around the bottom of the bag-shaped device 12, and when the bag-shaped device 12 is filled with organic impurities for fermentation and aeration is required, the output tube of the air compressor 22 is connected to the inlet end of the hose 16, and compressed air is delivered to the bottom of the bag-shaped device 12 through the hose 16 and then distributed through the microporous aeration tube 20. The air compressor 22 may be powered by alternating current, direct current, high pressure air, or even manually. Cover 24 is a plastic or woven cloth cover that is attached to the open portion of pouch-shaped device 12 to reduce odor emissions during fermentation.
The use of the fermentation apparatus 10 in livestock farms can provide many operational advantages and conveniences. The relevant raw materials are subjected to pretreatment before fermentation, which includes raw material collection, raw material preliminary treatment, raw material mixing and the like. The raw material is the planting waste which can be collected from local places, such as straw, stems and vines, weeds, fallen leaves, corn stalks, pond sludge, kitchen waste and the like, besides the livestock manure collection of the livestock farm. The primary treatment of the raw materials is to cut the materials as much as possible, which can increase the ventilation, increase the degree of decomposition and accelerate the decomposition of the raw materials. Then, the livestock manure and the chopped planting waste are mixed, a proper carbon-nitrogen ratio and humidity are maintained, soil microorganisms are added to assist fermentation, and the mixture, namely the to-be-fermented material, is filled into the bag-shaped device 12 for fermentation.
The fermented material is fermented in the bag-shaped device 12, which is easy to keep warm and moisture, and water seeps downwards due to gravity and finally accumulates at the bottom of the bag-shaped device 12, and when the air compressor 22 is used for inflating each time, the microporous aeration pipe 20 is soaked in water to generate bubbles to float upwards, the water is carried upwards by the way. The temperature is raised in the fermentation process, the water vapor at the bottom is gradually moved upwards, so that the humidity of the mixture is maintained between 40 and 60 percent during the fermentation, the oxygen content can be effectively regulated, and the fermentation temperature can be maintained, so that the direct effect is much quicker than the traditional compost aging. The decomposition can be completed within three to four weeks generally.
Besides the production efficiency of the fermentation device 10 is higher than that of the traditional compost, the other indexes of the fermentation device are obviously different. In terms of organic matter retention, the compost will be largely organic, while the fermentation device 10 will be substantially organic. In terms of the maintenance of nitrogen, phosphorus and potassium, the compost is seriously lost, and the fermentation device 10 is sufficiently maintained.
The fermentation device 10 can be folded and stored when not in use. When needed, the strap harness 14 can be pulled open and hung on a structure capable of resisting load. If one pocket 12 is not sufficiently loaded, more pockets can be hung. The air filter 22 supplies the required oxygen every day, and after the bag becomes thoroughly decomposed, the air filter 22 blows air upward from the bottom of the bag to reduce the water content.
Fig. 2 and 3 are schematic bottom structures of another foldable fermentation device. FIG. 2 shows a top view of another collapsible bag-shaped device 30 bottom structure. A holder 32 is provided within the bag-shaped device 30 to hold or position the microporous aeration tube 34. Microporous aerator pipe 34 is wrapped around the bottom of frame 32 from gas delivery fitting 36 inward in a clockwise direction, and the intersection of microporous aerator pipe 34 and frame 32 can be held in place with a thin thread until point , at end 38. FIG. 3 shows the upper portion of the cradle 32 in the bag-like device 30 with the hose 40 spiraling outward in a counterclockwise direction from the connector 36 to the air delivery connector 42.
When not in use, the bag-shaped device 30 is folded downwards, and the whole appearance is flat. When it is required to use, the bag-shaped device 30 is pulled up, and the air delivery joint 42 of the hose 40 is also pulled up, so that the object to be fermented can be loaded in the bag-shaped device 30 to start the operation.
Another advantage of the fermentation device 10 is that the temperature, humidity, degree of ventilation, and even degree of decomposition of the fermentation mixture in the bag-shaped device 12 can be regulated by managing the supply of compressed air at different times. This is advantageous in terms of practical management, and can improve the quality of the fermented product.
For example, at the start of fermentation, a sufficient amount of compressed air is supplied into the bag-shaped device 12, so that microorganisms are aerobically fermented and proliferated in large quantities under a condition of a sufficient supply of oxygen. When the number of microorganisms to be propagated is sufficient, the supply of compressed air is suspended to cause oxygen deficiency in the bag-shaped device 12, thus forcing the microorganisms to perform anaerobic fermentation. When the microorganism is subjected to anaerobic fermentation, biological enzymes, also commonly called ferment, are easily released, and the biological enzymes are applied to crops to help the crops to grow. Then the next period is started, oxygen is sufficiently supplied to make the microorganism supplement energy and reproduce, then oxygen supply is stopped, the microorganism is forced to perform anoxic fermentation, and then the biological enzyme is released.
The more the biological enzyme, i.e. the more the enzyme, the biological enzyme can help to decompose the organic matter, so that the fermentation time of the whole organic matter is shortened. For example, if aerobic fermentation is maintained all the time for a certain mixture ratio of organic mixture, it may take 6 weeks to make the organic mixture become decomposed. If aerobic, anoxic, aerobic, anoxic fermentation modes are adopted, 4 weeks may be required to thoroughly decompose the organic mixture. The biological bacteria grow and decompose the organic matters beside the biological bacteria in an aerobic state at the initial stage, release the biological enzyme to decompose the organic matters when the biological bacteria are in an anoxic state, and grow new biological enzyme again in the biological bacteria when the biological bacteria enter the aerobic state in the next period, so that the biological bacteria absorb small organic matters into the body and transfer the small organic matters to the new biological enzyme for decomposition, and the original biological enzyme outside the body still helps to decompose large organic matters into small decomposable matters. The more enzyme contained in the fertilizer, the better the grade of the fertilizer, and the better the growth of crops. Therefore, the fermentation modes of aerobic, anoxic, aerobic and anoxic have the effect of directly saving energy.
With the fermentation apparatus 10, the embodiment of the present invention further provides a fermentation method, including:
hanging a hanging strip for hanging the bag-shaped device, which is arranged on the foldable bag-shaped device, on movable equipment for carrying;
the materials to be fermented are contained in the bag-shaped device and fermented;
in the fermentation process, during aerobic fermentation, the hose is connected with an air compressor, and air is released to the bottom of the object to be fermented through the hose and an aeration pipe which is connected with the hose and is arranged at the bottom of the bag-shaped device, so that the air floats from the bottom of the object to be fermented; during anaerobic fermentation, the supply of air in the hose is suspended;
according to different substances to be fermented, the aerobic fermentation and the anaerobic fermentation are circularly used until the fermentation is finished.
Wherein, the bag-shaped device is a water-tight woven bag.
It can be seen that the fermentation device 10, with the bag-shaped device 12 or the bag-shaped device 30 attached with a hanging strip 14 for hanging, is supplied with compressed air by an air compressor 22, and is delivered to a microporous aeration pipe 20 at the bottom of the bag-shaped device through a hose 16 for air intake and fermentation. During operation, the fermentation system can preserve heat and moisture and can adjust the oxygen supply. The production efficiency is higher than that of the traditional compost, and the quality of the fermentation product is better than that of the traditional compost. The investment is less, the effect is quick, the operation can be expanded according to the requirement of the capacity, and the operation flexibility is far better than that of the traditional compost.
In summary, the foldable fermentation apparatus and the fermentation method according to the embodiments of the present invention suspend the bag-shaped device on the movable apparatus for carrying by the suspension belt, release air to the bottom of the object to be fermented by the aeration pipe, provide oxygen to the object to be fermented by floating the air, and perform fermentation by controlling the release and non-release of air in the aeration pipe to allow the object to be fermented to be aerobically fermented and anaerobically fermented. The fermentation device and the fermentation method have the advantages of simple fermentation method, low equipment cost, short fermentation time, no occupation of field, no need of compost turning and no loss of fertilizer nutrients in the fermentation process.
