Abstract

The present invention relates to a large-scale post-fermentation tunnel for mushroom substrate using a grid floor method. More specifically, it aims to enable efficient production of mushroom substrate piles by stably and uniformly supplying air to a large-capacity mushroom substrate pile. A sealed housing is partitioned into an entry space and a post-fermentation space. Within the post-fermentation space, a plurality of perforated plates are horizontally installed at a distance from the floor. The floor of this post-fermentation space is formed so that its height gradually increases in the longitudinal direction, thereby ensuring that air introduced from beneath the perforated plates is supplied uniformly across the entire mushroom substrate pile through the supply holes of the perforated plates toward the mushroom substrate pile placed on top of the perforated plates. Furthermore, the pressure inside the housing is maintained at a constant level by releasing the pressure to the outside through an exhaust damper when it exceeds a preset pressure. Additionally, the air supplied to the interior is maintained at a constant level by controlling whether or not it is heated according to the preset temperature inside the housing. This enables efficient and stable production of mushroom substrate piles in a large-scale post-fermentation tunnel using a grid floor method. It is about.

Description

Grid floor type large-scale button mushroom compost pasteurization tunnel The present invention relates to a large-scale post-fermentation tunnel for mushroom substrate using a grid bottom method, which supplies air uniformly and stably to a pile of mushroom substrate, and enables stable production of mushroom substrate by introducing air into the lower part of the pile of mushroom substrate in a sealed space while constantly maintaining the interior at a preset temperature and pressure. In general, as the demand for mushrooms increases due to their efficacy, the use of artificial cultivation is on the rise. The method of artificial cultivation involves forming a nutrient-rich substrate by combining waste cotton, sawdust, rice bran, cottonseed hulls, or miscellaneous grains, fermenting it, inoculating the fermented substrate with mushroom mycelium, transferring it to a culture room, and cultivating and growing it for a certain period to produce mushrooms. In the mushroom cultivation method used in this way, a substrate is formed and fermented under certain conditions to cultivate high-quality mushrooms. This fermentation method typically involves forming a fermentation substrate of a predetermined size, adjusting the moisture using manual labor or a tiller, and then stacking and fermenting it for about 10 days. Mushroom substrates are prepared with a moisture content of 60-70%, and oxygen is supplied to the interior of the substrate by turning it over twice a day to provide oxygen for aerobic fermentation. However, this method makes it impossible to supply oxygen to the interior of the substrate in a uniform distribution, and it results in the inconvenient task of supplying oxygen to the interior of the substrate through physical work. Since these methods rely on natural fermentation, artificial control of the microbial community and microbial succession is impossible, making it difficult to control the amount of air and moisture in the medium. In particular, the problem of anaerobic conditions arose because it was difficult for air to enter the formed medium. As the internal environment of the substrate becomes anaerobic, damage caused by fungi and anaerobic organisms increases, and the generation of harmful substances such as ammonia and methane gas not only worsens the working environment but also leads to contamination of the substrate, resulting in a higher failure rate in mushroom cultivation and the inability to cultivate high-quality mushrooms.
