Description

Technical Field

[0001] The invention belongs to the technical field of edible fungus cultivation devices, and in particular relates to an edible fungus cultivation bin with cold and hot split-flow air supply. Background Art

[0002] Edible fungi refer to large, edible fungi (large fungi), commonly known as mushrooms. There are more than 350 known edible fungi in China, most of which belong to the subphylum Basidiomycota.

[0003] At present, most common edible fungi are cultivated artificially, and the cultivation of edible fungi requires relatively suitable temperature and humidity. It is more common to cultivate edible fungi in box-type culture chambers. During the cultivation process, the temperature and humidity of the air in the culture chamber need to be controlled, so air temperature and humidity control devices are needed to achieve this purpose. However, the usual method for controlling the temperature in the culture chamber is to directly heat or cool the outdoor air to a certain temperature and then input it into the culture chamber. Although this air supply method of inputting air at a certain temperature can achieve temperature control in the culture chamber, due to the relatively stable temperature of the input air flow, the air circulation in the culture chamber is poor, which is not conducive to humidity balance. Summary of the invention

[0004] The present invention aims at solving the problems in the prior art and proposes the following technical solutions:

[0005] An edible fungus culture bin with hot and cold split air supply, comprising:

[0006] The warehouse body is a box-type structure with a culture rack inside;

[0007] The air supply channels are distributed at the top and the bottom of the warehouse body. Low-temperature gas flows through the air supply channels distributed at the top, and high-temperature gas flows through the air supply channels distributed at the bottom.

[0008] Preferably, the air supply channel is arranged at the top corner and the bottom corner of the warehouse body.

[0009] Preferably, the air supply channel is arranged in the middle between the bottom corner and the top of the warehouse body.

[0010] Preferably, the air supply channel includes:

[0011] A venturi tube, wherein the venturi tube has a compressed gas inlet, an outlet and a negative pressure adsorption chamber;

[0012] A water storage box, the top of which is connected to the negative pressure adsorption chamber, and a water storage sponge is arranged inside the water storage box;

[0013] The pipe body has an upper air hole and a lower air hole which are opposite to each other, and the upper air hole is connected to the water storage box;

[0014] The annular diaphragm is sleeved on the outside of the pipe body, the circumference of the annular diaphragm is greater than the outer circumference of the pipe body, and the annular diaphragm is deformed by force to block the upper pore or the lower pore.

[0015] The beneficial effects of the present invention are as follows: by separately setting up cold and hot air supply channels to supply air respectively, temperature control is achieved by utilizing the convective heat exchange of the airflow, and at the same time, convection based on the temperature difference forces the air circulation in the warehouse to improve the uniform distribution of water vapor, which is beneficial to humidity balance; in addition, further improving the structure of the air supply channel can achieve the purpose of controllable humidification in the warehouse.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Figure 1 What is shown is a schematic diagram of the structure of the culture bin of the present invention. Figure 2 Another structural schematic diagram of the culture chamber of the present invention is shown. Figure 1 and 2 In the embodiment, the culture chamber comprises a chamber body 10, a culture rack 20, an upper air supply channel 31 and a lower air supply channel 32. The culture rack 20, the upper air supply channel 31 and the lower air supply channel 32 are all arranged in the chamber body 10. The upper air supply channel 31 is arranged at the top of the chamber body 10, and the lower air supply channel 32 is arranged at the bottom of the chamber body 10. Figure 1 and Figure 2 The difference between the culture chambers shown is that the upper air supply channel 31 is arranged in a different position. Figure 1 In the embodiment, the upper gas supply channel 31 is arranged at the top corner of the warehouse body 10 for providing low-temperature gas, and the lower gas supply channel 32 is arranged at the bottom corner of the warehouse body 10 for providing high-temperature gas; Figure 2 In the embodiment, the upper air supply channel 31 is arranged at the top middle of the warehouse body 10 for providing low-temperature gas, and the lower air supply channel 32 is arranged at the bottom corner of the warehouse body 10 for providing high-temperature gas.

[0022] Assume that the required temperature for cultivation in the cultivation chamber is t1. Then, the upper air supply channel 31 supplies gas at a temperature of t2, where t2 < t1, and the lower air supply channel 32 supplies gas at a temperature of t3, where t1 < t3. In this way, there are two streams of gas supplied into the chamber body 10, and there is a temperature difference between the two gas streams. Under the influence of the gas stream temperature difference, the low-temperature gas stream input by the upper air supply channel 31 will sink, and the high-temperature gas stream input by the lower air supply channel 32 will rise. The two gas streams achieve temperature neutralization through heat exchange during the convection process, reaching the target temperature t1. This process involves the convection of different gas streams, thereby forcing the air in the chamber body 10 to circulate, making the water vapor distribution in the chamber body 10 uniform and facilitating the humidity balance in the entire chamber body 10.

[0023] Combined with Figure 1 and Figure 2 the layout differences between the upper air supply channel 31 and the lower air supply channel 32 in [relevant content], in the present invention, the upper air supply channel 31 and the lower air supply channel 32 are only restricted by the height difference in the vertical position. The upper air supply channel 31 and the lower air supply channel 32 can either correspond in the vertical position or be staggered in the vertical position.

[0024] Since common air treatment devices, such as common air-conditioning units, do not have an obvious function of humidifying air, and the cultivation process of edible fungi requires a relatively high air humidity, it is necessary to separately add a humidifying device to humidify the air, which also leads to high energy consumption problems. Therefore, in this embodiment, the upper air supply channel 31 and the lower air supply channel 32 are also improved to facilitate air humidification.

[0025] In the following content, the upper air supply channel 31 and the lower air supply channel 32 are collectively referred to as the air supply channel 30 for the convenience of description.

[0026] Figure 3The structure diagram of the air supply channel 30 is shown. The air supply channel 30 includes a pipe body 310, a water storage box 320, and a venturi tube 330, which are connected in sequence. The pipe body 310 is provided with an upper air hole 311 and a lower air hole 312 which are arranged opposite to each other. The number of the upper air hole 311 and the lower air hole 312 can be one or more, and the number of the upper air hole 311 and the lower air hole 312 can be the same or different. The corresponding position is that the upper air hole 311 is arranged upward and the lower air hole 312 is arranged downward. The water storage box 320 is arranged outside the pipe body 310, and the water storage box 320 is arranged outside the upper air hole 311. A water storage cavity is formed inside the water storage box 320, and a water storage sponge 321 is arranged in the water storage cavity. The upper part of the pipe body 310 is connected to the water storage cavity in the water storage box 320 through the upper air hole 311, and the top of the water storage box 320 is opened. The venturi tube 330 is arranged at the top opening of the water storage box 320. The venturi tube 330 has a compressed gas inlet 331, an air outlet 332 and a negative pressure adsorption cavity 333. The negative pressure adsorption cavity 333 is downwardly connected to the top opening of the water storage box 320. An annular diaphragm 340 is also sleeved on the outside of the pipe body 310. The circumference of the annular diaphragm 340 is greater than the outer circumference of the pipe body 310. The annular diaphragm 340 penetrates the outer wall of the water storage box 320 so that the annular diaphragm 340 can move relative to the pipe body 310.

[0027] like Figure 3 As shown, in the normal state, since the annular diaphragm 340 has the ability to deform and the water storage sponge 321 is in the normal state, the upper half of the annular diaphragm 340 is in contact with the pipe body 310. In this state, the water stored in the water storage sponge 321 will moisten the annular diaphragm 340, so that the upper air hole 311 is blocked by the annular diaphragm 340; and the lower half of the annular diaphragm 340 is deformed downward under the action of gravity and separated from the pipe body 310, and the lower air hole 312 is in an open state, so that the gas in the pipe body 310 can be discharged from the lower air hole 312 and transported to the warehouse body 10.

[0028] Figure 4 FIG. 2 is a schematic diagram showing another working state of the air supply channel 30 . Figure 4In the embodiment, compressed air is input into the compressed gas inlet 331, thereby forming a negative pressure adsorption chamber 333. Since the negative pressure adsorption chamber 333 is connected to the inner cavity of the water storage box 320, the annular diaphragm 340 blocks the upper air hole 311 in the initial state. Under the action of the negative pressure adsorption chamber 333, the annular diaphragm 340 will deform upward to expose the upper air hole 311. The annular diaphragm 340 will also squeeze the water storage sponge 321 at the same time, so that the water stored in the water storage sponge 321 maintains a tendency to seep out, and the gas in the pipeline body 310 is ejected through the upper air hole 311 through the water storage box. The sponge 321 brings the moisture in the water storage sponge 321 into the venturi tube 330 and sprays it out through the air outlet 332. This process can humidify the warehouse body 10, and the air pressure of the gas in the pipeline body 310 sprayed out through the upper air hole 311 can also help maintain the state of the annular diaphragm 340; on the other hand, when the annular diaphragm 340 is deformed, the lower part will be pulled up and fit with the pipeline body 310, thereby blocking the lower air hole 312, so that all the gas in the pipeline body 310 is sprayed out after being humidified through the water storage box 320 and the venturi tube 330.

[0029] In this embodiment, the material of the annular diaphragm 340 adopts a polymer material in the prior art. Such polymer material should have the characteristic of a small tensile deformation rate to ensure the sensitivity of the annular diaphragm 340 in blocking the upper pore 311 or the lower pore 312 .

[0030] The water storage box 320 and the venturi tube 330 are arranged in pairs, that is, one water storage box 320 is connected to one venturi tube 330 , and the venturi tube 330 is arranged on the pipeline body 310 at intervals.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
