Embodiment Construction
[0014] In conjunction with the accompanying drawings, the implementation of the present invention is provided as follows:
[0015] like figure 1 As shown, the sterilization chamber 1 is provided with a sterilization chamber door 1 for feeding and discharging, and a coating 5 is applied to the walls inside the sterilization chamber 1 to keep the walls clean and smooth. A crane or a shelf for hanging the growth container 7 is arranged therein, and the growth container 7 is placed in the growth bracket 8 and then hung on the truck or placed on the shelf. Growth container 7 has two kinds, and a kind of is for fully enclosed structure, as figure 2 As shown, the culture medium 9 is packed into the growth container 7, and the container mouth is sealed after the air is sucked out. The other is a semi-closed structure, such as image 3 As shown, the culture medium 9 is packed into the growth container 7 with a filter opening, sealed by a filter plug, and when the air in the growth ...

The invention discloses a dry heat sterilization method for edible mushrooms culture medium, which adopts dry heat gas to perform sterilization treatment on culture medium after the culture medium is placed in a sterilization room. The method adopts the dry heat gas to perform sterilization treatment on the culture medium, not only cannot erode the sterilization room or an inner cavity and metal components of a sterilization container, but also ensures that the heat transfer temperature on the culture medium during the sterilization is gradually increased due to the fact that the heat transfer speed of the dry heat gas is slower than that of water vapor and the temperature can be regulated and controlled according to the need; and the process is favorable for the fermentation of the culture medium and ensures that the culture medium has adequate fermentation time. The culture medium can produce a large amount of beneficial substances needed by the growth of crops after the fermentation, can produce a lot of heat during the fermentation, can save the supply of heat energy, purify sterilization environment, reduce production cost, and improve production efficiency.
Description
technical field [0001] The invention belongs to the technical field of crop cultivation and sterilization, and mainly relates to a dry heat sterilization method for crop medium. It can be widely used in the cultivation and production of edible fungi, vegetables, flowers and other crops. Background technique [0002] As we all know, the cultivation of crops such as edible fungi must first sterilize their culture medium. At present, the commonly used method is to stack the medium in the sterilization room or the sterilization container, or put the medium into the growth bag first and then put it into the sterilization room or the sterilization container, and then pass it into the high temperature steam for sterilization , or place it directly in the sterilizer, and heat the water in the sterilizer to boil to generate high-temperature steam for sterilization. This sterilization method has the following disadvantages: [0003] 1. Due to the fast heat transfer speed and high t...
