Bag-cultivated edible fungi liquid spawn inoculation sealing device and operation process thereof

Abstract

The invention discloses a bag-cultivated edible fungi liquid spawn inoculation sealing device and an operation process thereof, which is mainly used for automatic inoculation production of edible fungi liquid spawn. The invention uses the cylindrical inoculation sealing device with a slant, which is controlled sequentially by a program under sterile environment; first, a cultivation bag filled with cultivation materials is pierced with a hole; then, parts of the cultivation materials are poured out to leave enough inoculation space, an upper cover plate of the inoculation sealing device head is pushed open by controlling a proportional valve when the liquid spawn is pushed under certain pressure, fungi solution is injected rapidly and quantitatively, and the cover plate is reset under the action of a return spring; finally, the inoculation sealing device head is returned to the upper position of the cultivation bag to leave out enough sealing space, the cover plate is pushed open by controlling the proportional valve when sealing mud is pushed under certain pressure, and the sealing mud is injected rapidly and quantitatively, the sealing of an inoculation port is realized, and one-time quantitative inoculation and sealing operation are accomplished. The invention realizes the integration of liquid spawn inoculation and sealing, the degree of automation is high, the structure is compact and simple, and the cost is low.

Description

technical field [0001] The invention relates to a sealing device for inoculating liquid strains of edible fungi in bags and an operation process thereof, which belongs to the technical field of mechanical manufacturing and is mainly used for automatic inoculation production of liquid strains of edible fungi. Background technique [0002] At present, there are mainly two forms of edible mushroom production: bag planting and bottle planting. Among them, the use of bottle-grown edible mushrooms requires repeated opening and screwing of the bottle caps during the inoculation and cultivation process, which is easy to damage the bottle caps and bottles, resulting in low production efficiency and high costs. Therefore, most farmers who produce edible fungi use bag cultivation. At present, the bag-grown edible fungi production equipment is mainly aimed at solid strains. As the technology of producing edible fungi using liquid strains matures, it is necessary to have related equipmen...

Problems solved by technology

Its disadvantages are: 1. Since the drainage hole is directly in contact with the cultivation material, the drainage hole may still be blocked; 2. The bacterial liquid is directly discharged into the cultivation material, and the drainage resistance is large, and the drainage speed is slow, which affects the inoculation productivity; 3. The operation of pulling out the inoculation needle while injecting and the manual sealing operation with sealing mud are very inconvenient, the degree of automation is low, and it is easy to contaminate the liquid bacteria
