Description

Technical Field

[0001] This utility model relates to the field of peanut ventilation, mold inhibition and drying, and in particular to a prefabricated peanut ventilation and mold inhibition device. Background Technology

[0002] Newly harvested peanuts have a high initial moisture content (40%-50%), making them highly susceptible to heating and mold growth if not dried promptly. Mold growth not only leads to a rapid deterioration in peanut quality (manifesting a musty smell, discoloration, and rotting), causing significant economic losses, but more importantly, some molds (especially Aspergillus flavus) produce highly toxic toxins such as aflatoxin.

[0003] Currently, peanuts mainly rely on natural sun-drying after harvest, which is inefficient in terms of water reduction, has a long drying period, and carries a high risk of mold growth even in the early stages of drying. Furthermore, open-environment drying easily leads to secondary pollution, directly threatening food safety. In particular, it is highly dependent on weather conditions, with annual losses exceeding one million tons (moldy rates reaching 10%-30%) due to rainy weather. As peanut mechanization levels continue to improve and harvesting becomes increasingly concentrated, there is a significant shortage of drying space. While mechanized drying is more efficient in terms of water reduction, the equipment investment and operating costs (fuel and electricity) are expensive for farmers. In addition, improper temperature control can easily lead to a decline in peanut quality and a reduced germination rate. Moreover, its economic viability and applicability also face challenges in scenarios requiring rapid post-harvest processing to inhibit mold growth.

[0004] Therefore, there is an urgent need for a peanut drying technology that is economical, efficient, safe, environmentally friendly, easy to operate, and low-cost, specifically designed for the high moisture content of newly harvested peanuts. This technology should be able to rapidly and uniformly reduce the moisture content (moisture reduction) and temperature (heat dissipation) inside the peanut pile during the critical window of high mold risk after harvest, thereby directly inhibiting mold growth and reproduction, blocking the risk of aflatoxin production at the source, and laying the foundation for safe storage, transportation, and processing.

[0028] The embodiments of this utility model will be described with reference to the accompanying drawings.

[0029] like Figure 1 , 2 As shown in Figure 8, this embodiment discloses a prefabricated peanut ventilation and mold suppression device, including an air supply component 2, a prefabricated silo 11, and a gas distribution cylinder 10; an air duct 9 is detachably installed between the air supply component 2 and the gas distribution cylinder 10; the gas distribution cylinder 10 is placed inside the prefabricated silo 11; a first ventilation hole 114 is provided on the wall of the prefabricated silo 11; a second ventilation hole 117 is provided on the cylinder body of the gas distribution cylinder 10.

This method allows two adjacent perforated plates 111 to be assembled and form a rotating connection.

[0031] In this embodiment, eight perforated plates 111 are rotatably connected by a first rotating shaft block 112, a second rotating shaft block 115, and a rotating shaft 116, forming an octagonal prism-shaped silo with a regular octagonal cross-section. In other embodiments, the number of perforated plates 111 in the assembled silo 11 can be a natural number greater than or equal to 3. For example, if the number of perforated plates is 4, it can be assembled into a quadrangular prism-shaped silo with a regular quadrilateral cross-section; if the number of perforated plates is 5, it can be assembled into a pentagonal prism-shaped silo with a regular pentagonal cross-section. Further examples will not be provided here.

[0032] Furthermore, such as Figure 7 As shown, one of the perforated plates 111 of the prefabricated silo 11 has a discharge port; a silo door 13 is hinged to the discharge port; the silo door 13 has a threaded through hole, and one of the perforated plates 111 has a corresponding threaded slot at the position corresponding to the threaded through hole. The silo door 13 can be temporarily fixed to one of the perforated plates 111 by bolts with handles. The silo door 13 has a third vent.

[0033] Furthermore, such as Figure 1 , 2 As shown in Figures 6 and 8, three sets of inspection holes 12 are arranged sequentially from top to bottom on one or two perforated plates 111 of the assembled silo 11.

[0034] In this embodiment, such as Figure 1 , 2 As shown in Figure 8, the gas distribution cylinder 10 is a hollow cylinder; one end of the air duct 9 is connected to the air guide duct 15 by a clamp; threaded holes are evenly opened along the circumferential direction at the top of the gas distribution cylinder 10 and the bottom of the air guide duct 15, and the top of the gas distribution cylinder 10 and the bottom of the air guide duct 15 can be detachably connected by bolts and the aforementioned threaded holes.

[0035] In this embodiment, such as Figure 1 , 2As shown, the air supply assembly 2 includes a fan 21, a control cabinet 22, and a frame 23; the fan 21 and the control cabinet 22 are mounted on the frame 23; the fan 21 and the control cabinet 22 are electrically connected; the air outlet of the fan 21 and one end of the air duct 9 are detachably connected; in this embodiment, the air outlet of the fan 21 and one end of the air duct 9 are connected by a clamp. The fan 21 and the control cabinet 22 are existing technologies and will not be described in detail here.

[0036] In this embodiment, the device operates as follows:

[0037] The assembled silo 11 is formed by assembling eight perforated plates 111 and a rotating shaft 116; the gas distribution cylinder 10 is placed inside the assembled silo 11; the gas distribution cylinder 10 is fixedly connected to the air guide duct 15 by bolts; the air guide duct 15 is connected to one end of the air duct 9 by clamps, and the other end of the air duct 9 is connected to the air supply assembly.

[0038] After the device is assembled, peanuts are placed in the loading area between the prefabricated silo 11 and the gas distribution cylinder 10. The air supply component 2 realizes air transmission. The air is introduced into the gas distribution cylinder 10 through the air duct 9 and the air guide duct 15. The gas is sent into the prefabricated silo 11 through the gas distribution cylinder 10. The forced ventilation removes the moisture and heat from the peanut pile and the moisture from the peanuts themselves, thereby achieving ventilation and dehumidification of the peanut pile and inhibiting the peanuts from becoming moldy.

[0039] Furthermore, the technical effectiveness of this device was tested through on-site experiments, as follows:

[0040] The weather during the field test was mainly cloudy and rainy, with low temperatures and high humidity, which was not conducive to rainfall on the peanuts. The weather conditions during the field test are shown in the table below:

[0041] Weather conditions during field testing

[0042]

[0043] The peanut variety used was Kainong 1760, a high-oleic, small-pod peanut. After field harvest, the peanuts were directly picked and loaded into equipment for a ventilation-induced mold-suppressing and drying experiment. The initial moisture content of the newly harvested peanuts was 45.08% ± 0.52%, and the processing volume of the newly harvested wet peanuts was 1650 kg. A total of 6 sampling and testing points were set up at the top, middle, and bottom layers of the peanut pile. A natural sun-drying control group was also set up. Samples were taken every 12 hours, and the moisture content was tested using national standard methods. All the above operations were carried out at the same time and place.

[0044] The measurement results were as follows: the initial moisture content of peanuts was 45.08% ± 0.52%. The moisture content of peanuts at different locations in the treatment group decreased continuously over time. On the 6th day (144 h), the moisture content of peanuts at all locations decreased to below the safe moisture level of 10%, with an average moisture content of 8.97% ± 0.81%. However, the moisture content of peanuts in the control group decreased slowly, and the moisture content was still as high as 17.18% ± 0.16% on the 6th day.

[0045] Equipped with a "real-time temperature and humidity monitoring system", it enables timed and constant humidity start-stop controllers for precise control.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
