Description

Technical Field

[0001] This utility model relates to the field of industrialized cultivation technology of edible fungi, specifically a ventilation system for an intelligent cultivation chamber for edible fungi. Background Technology

[0002] Edible fungi refer to large, edible fungi with large fruiting bodies that grow as white or light-colored mycelium in environments rich in organic matter. Traditional edible fungi cultivation relies heavily on seasonal natural environments, resulting in problems such as short production cycles, low yields, and unstable quality. With the development of industrialized technology, smart edible fungi cultivation chambers, which combine intelligent mushroom houses with substrate substrates and IoT environmental control technologies, have significantly improved edible fungi production capacity. These chambers are equipped with temperature and humidity sensors; however, the ventilation systems of existing smart edible fungi cultivation chambers still face the following technical bottlenecks.

[0003] Typically, a smart mushroom cultivation chamber includes a cultivation chamber, an air conditioning unit, air supply ducts, return air ducts, and several cultivation shelves. The air conditioning unit is connected to the air supply and return air ducts. The cultivation shelves are located inside the cultivation chamber and consist of multiple layers of shelves spaced vertically. Traditional cultivation chambers use a single air inlet / outlet for ventilation, which can easily lead to dead air zones and localized temperature and humidity fluctuations, inhibiting mycelial growth and causing deformed fruiting bodies (such as thin caps and long, thin stems), resulting in a lower marketability. Furthermore, since each layer of the cultivation shelves is used for cultivating edible fungi, the fermented substrate on the shelves accumulates at a high density. Traditional air supply airflow cannot penetrate the substrate on the lower layers, which are further away, easily leading to insufficient oxygen supply and incomplete fermentation of the edible fungi on the lower layers.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a ventilation system for a smart mushroom cultivation chamber, including a cultivation chamber 1, an air conditioning unit 2, air supply ducts 3, return air ducts 4, and several cultivation shelves 5. The air conditioning unit 2 is connected to the air supply ducts 3 and return air ducts 4. The cultivation shelves 5 are installed inside the cultivation chamber 1 and include multiple layers of shelves 6 spaced vertically. The number of air supply ducts 3 is the same as the number of shelves 6, and each air supply duct 3 is located above each shelf 6. Multiple air outlets are spaced along the length of the shelf 6. The number of return air ducts 4 is the same as the number of cultivation shelves 5, and the return air ducts 4 are located at the bottom of the cultivation shelves 5. Multiple return air outlets are spaced along the length of the shelf 6.

[0025] The various shelves 6 of the aforementioned planting rack 5 are used for planting edible fungi. Fresh air is directly delivered to the surface of the mycelium of the edible fungi on the shelves 6 through the air supply duct 3 and air outlets, promoting aerobic metabolism and inhibiting the growth of anaerobic bacteria. The air supply duct 3 at the top layer can be installed under the ceiling inside the planting chamber 1.

[0026] In this embodiment, there are three planting shelves 5, and therefore three return air ducts 4. Each planting shelf 5 includes eight shelves 6, and therefore eight air supply ducts 3 are provided for each planting shelf 5, for a total of twenty-four air supply ducts 3. Of course, in other embodiments, other numbers of planting shelves 5 and shelves 6 can be provided as needed, and no further restrictions are imposed here.

[0027] Preferably, the air supply duct 3 is a fabric duct, which is a cloth duct. By selecting a fabric duct made of fiber fabric, the air outlet area can be large and the air velocity can be low. The permeable air supply can cover the entire cross section of the material layer on the shelf, avoiding the airflow dead zone of traditional metal ducts.

[0028] In addition, the air supply duct 3 is preferably a circular duct or an elliptical duct; the specific shape of the air supply duct 3 is selected according to the width of the shelf 6 (the width of the material surface). If the shelf width is less than or equal to 0.6m, a circular duct is selected; if the shelf width is greater than 0.6m, an elliptical duct is selected.

[0029] Regarding the location of the air outlet opening in the air supply duct 3, an air outlet can be provided at the bottom and / or lower side of the air supply duct 3; further, it is preferable to evenly distribute the air outlets at the bottom and lower side of the air supply duct 3, with the diameter of each air outlet being 1-1.5mm; the spacing between adjacent air outlets is ≤2m to avoid condensation; the air velocity at the air outlet is preferably controlled at 0.1-0.3m / s.

[0030] In order to ensure smooth airflow and replacement within the planting chamber 1, the return air duct 4 of this invention is located at the bottom of the entire planting shelf 5, while the supply air duct 3 is located above the shelf 6, so as to achieve air supply from the top and return from the bottom. This results in lower supply air temperature and higher density, with cold air and fresh air sinking down and return air being drawn back at the bottom. This ensures that the cold air and oxygen are evenly distributed on the edible fungus substrate layer of the shelf.

[0031] Preferably, a return air inlet is provided at the bottom and / or lower side of the return air duct 4, so that the exchanged air can be drawn away directly from the bottom, thereby better ensuring the smooth airflow organization of the entire planting chamber 1; the return air velocity of the return air inlet is preferably controlled at 0.6-1.0m / s.

[0032] Multiple supply air ducts 3 are connected to the air conditioning unit 2 via a first connecting pipe assembly 8; several return air ducts 4 are connected to the air conditioning unit 2 via a second connecting pipe assembly 9. In addition, the air conditioning unit 2 may also be connected to a fresh air duct. The air conditioning unit 2 of this utility model is prior art, and its specific structure and working principle will not be elaborated here.

[0033] In addition, this utility model may also include two exhaust pipes 7, which are respectively installed on the ground on both sides of the wall inside the planting chamber 1. Multiple exhaust ports are spaced along the length of each exhaust pipe 7, and the exhaust ports can be specifically located at the lower side of the exhaust pipe 7. An exhaust fan is connected to each exhaust pipe 7, and the exhaust velocity can be set below 0.8 m / s. When the exhaust is not activated, the valve of the fresh air duct is preferably opened 3-5% to prevent positive pressure in the planting chamber 1 and to avoid pollution from outdoor air. When it is necessary to reduce the carbon dioxide concentration in the planting chamber 1 and the exhaust is activated, all valves of the interlocking fresh air duct are opened to replace the gas in the planting chamber 1. When the carbon dioxide concentration in the planting chamber 1 reaches the set lower limit, the exhaust is closed and the opening degree of the fresh air duct valve is lowered.

[0034] Compared with existing technologies, this utility model provides a ventilation system for a smart mushroom cultivation chamber, which has the following beneficial effects: The air supply duct of this utility model has multiple air inlets spaced along the length of the shelf, and the return air duct has multiple return air inlets spaced along the length of the shelf. Furthermore, the air supply duct is located above the shelf, and the return air duct is located at the bottom of the cultivation shelf. Compared with the traditional single air inlet / outlet design, this utility model uses multiple air inlets / outlets and a top-supply, bottom-return design, which can better ensure smooth airflow within the cultivation chamber, better avoid dead air zones and local temperature and humidity fluctuations, thus better preventing inhibited mycelial growth and deformed fruiting bodies, thereby improving the yield of commercial edible mushrooms. In addition, the number of air supply ducts in this utility model is the same as the number of shelves, and each shelf has an air supply duct above it, allowing the airflow to penetrate the mushroom bed on each shelf effectively, thus better preventing insufficient oxygen supply and incomplete fermentation of the mushrooms on the lower shelves. Through the above methods, this utility model can make the airflow in the planting chamber more uniform and stable, thereby optimizing the growth state of edible fungi and effectively improving the quality and yield of edible fungi production.
