Description

Technical Field

[0001] The utility model relates to the technical field of bacterial strain culture equipment, in particular to a tunnel type Daqu culture device. Background Art

[0002] Brewing technology has a long history in my country. In the brewing industry and condiment brewing industry, a large proportion of koji is made in the form of bricks due to product needs. The current block koji making mode is that after the koji blocks are made, they are manually placed on a culture rack similar to a shelf, and the culture rack is moved to a sealed culture room, where microorganisms grow and reproduce on the koji blocks. Because the culture room has a large space, it is impossible to achieve consistent environmental conditions such as temperature and humidity in the entire area, and it is impossible to automatically adjust the suitable environment required for microbial growth. It is necessary to manually adjust the position of the koji blocks and turn the koji blocks, which is very labor-intensive. In addition, block koji is generally high-temperature koji, and microorganisms are suitable for growing in a high-temperature and high-humidity environment, which makes the working environment of workers poor. In this environment, high-intensity physical labor is very likely to cause physical discomfort, and the manual production efficiency is low, and the investment cost of the culture room is high.

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0042] like Figure 1-2 As shown, the tunnel-type Daqu culture device comprises: a qu room 100, a circulating air duct 200, a fan 203, an air inlet door 201, an air exhaust door 202 and a steam pipeline 400. Among them, a plurality of qu racks 500 are placed in the qu room 100, each qu rack 500 is arranged in an independent space, and each is provided with a qu rack air inlet 501 and a qu rack air outlet 502; the circulating air duct 200 is connected with the qu rack air inlet 501 and the qu rack air outlet 502; the fan 203 is arranged in the circulating air duct 200 between the qu rack air inlet 501 and the qu rack air outlet 502; the air inlet door 201 and the air exhaust door 202 are arranged on the circulating air duct 200 between the qu rack air inlet 501 and the qu rack air outlet 502; and the steam pipeline 400 is connected with the circulating air duct 200. The room 100 is also provided with a room temperature and humidity probe 101 for measuring the room environment temperature and humidity.

[0043] As a preferred solution of this example, each of the curved rack air inlet 501 and the curved rack air outlet 502 of the curved rack 500 is provided with an independent curved rack air door opening and closing mechanism 300. Specifically, Figure 3 As shown, the curved frame air door opening and closing mechanism 300 includes: an air door 301 and a cylinder 302; the air door 301 is arranged at the curved frame air inlet 501 / curved frame air outlet 502; the free end of the piston rod of the cylinder 302 is connected to the air door 301 through a connecting rod 303, and when the piston rod of the cylinder 302 is extended, the air door 301 is driven to move through the connecting rod 303 to open the curved frame air inlet 501 / curved frame air outlet 502. In this embodiment, the connecting rod 303 is hinged to one end of the air door 301, and the other end of the air door 301 is hinged to one end of the connecting rod, and the field end of the connecting rod is hinged to the fixed wall of the curved frame air inlet 501 / curved frame air outlet 502 to maintain the stability of the air door 301 being opened. Of course, according to the structural characteristics of the curved frame air inlet 501 / curved frame air outlet 502, the air door 301 can be directly pushed and pulled by the cylinder 302 to play the role of opening and closing the air door 301.

[0044] As a preferred solution of this example, a duct temperature probe 204 is provided in the circulating duct 200, and a steam control valve 401 is provided on the steam pipeline 400; the duct temperature probe 204 and the steam control valve 401 are connected to a control system, and when the duct temperature probe 204 detects that the temperature inside the circulating duct 200 is lower than the set value, the steam control valve 401 opens to increase the temperature. When the temperature is higher than the set value, the air inlet door 201 and the exhaust door 202 are opened to allow fresh air to enter and hot air to be discharged, and the ventilation volume can be controlled by controlling the blade angles of the air inlet door 201 and the exhaust door 202.

[0045] In addition, a humidity probe 205 and a carbon dioxide concentration sensing probe 206 are provided in the circulating air duct 200; the circulating air duct 200 is also connected to a compressed air pipeline 600 and a water inlet pipeline 700; the compressed air pipeline 600 and the water inlet pipeline 700 are respectively connected to a compressed air control valve 601 and a water inlet control valve 701; the humidity probe 205, the carbon dioxide concentration sensing probe 206, the compressed air control valve 601 and the water inlet control valve 701 are connected to the control system. The water inlet pipeline 700 is connected to a nozzle. When humidification is required, the compressed air control valve 601 and the water inlet control valve 701 humidify and add oxygen through the humidification nozzle, and also bring the atomized water to the inside of the curved frame through the fan 203 to meet the requirement of controlling the humidity inside the air duct. When the humidity or carbon dioxide concentration is too high, the exhaust door 202 is opened to discharge the gas.

[0046] As a preferred solution of this example, Figure 3 As shown, each set of curved racks 500 is provided with a curved rack temperature probe 503, which is connected to a control system. According to the different culture environments required by the curved blocks on each set of curved racks, the steam control valve 401 can be adjusted by the temperature measured by the curved rack temperature probe 503, and the opening and closing of the curved rack air inlet 501 / curved rack air outlet 502 can be controlled separately, so as to adjust the temperature of each set of curved racks separately. When the temperature and humidity of the set of curved racks 500 need to be controlled, the curved rack air inlet 501 and the curved rack air outlet 502 of the set of curved racks 500 are both in an open state, connected to the circulating air duct 200, and circulated.

[0047] The whole cultivation process of the tunnel-type Daqu cultivation device of the present application can be fully automatically controlled, and the cultivation process does not require manual participation. Manual adjustment of the position of the qu block or flipping of the qu block can provide the most suitable growth environment, high production efficiency, and improved production capacity; the cultivation qu rack has a compact and regular structure, and the temperature of the directional qu rack can be controlled through the qu rack air door. The layout does not require high production workshop space, and the investment cost is low.
