Air inlet structure for large-scale high-temperature sterilization furnace for edible fungi

Abstract

The invention discloses an air inlet structure for a large-scale high-temperature sterilization furnace for edible fungi, and belongs to the technical field of edible fungus cultivation. The air inletstructure for the large-scale high-temperature sterilization furnace for the edible fungi comprises a sitting groove formed in the ground, wherein a furnace body is mounted in the sitting groove; a sink tank is arranged in the center of the bottom of the sitting groove; one end of an air supply pipeline is connected with a high-temperature steam source, and the other end of the air supply pipeline penetrates into the sink tank; a disc is arranged on the bottom of the sitting groove, and a through hole opposite to the sink tank is formed in the center of the disc; a plurality of circles of breathable bricks are placed on the disc; a plurality of horizontal flow guide pipes which are radially arranged around the through hole of the disc are placed on the disc; and through holes which are uniformly distributed are formed in the pipe walls of the horizontal flow guide pipes. The radial horizontal flow guide pipes and the circumferentially arranged air bricks are adopted, high-temperaturesteam delivered by the air supply pipeline is uniformly distributed in the whole furnace body, so that material bags are heated uniformly, and the high-temperature sterilization effect is guaranteed;and due to multi-layer arrangement, each layer is provided with an independent high-temperature steam flow guide device, stacking of the material bags of different layers is easy to control, and the sterilization efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of edible fungi cultivation, in particular to an air intake structure for a large-scale high-temperature sterilization furnace for edible fungi. Background technique [0002] There are more than 2,000 species of edible fungi in the world, and 40 to 50 species can be artificially cultivated on a large scale. However, there are 938 kinds of edible fungi in my country, and there are more than 50 kinds that can be cultivated artificially. Before artificially cultivating edible fungi, fill the material bag with the material, and then remove the miscellaneous bacteria in the material, [0003] The commonly used method for removing miscellaneous bacteria in the prior art is to use a high-temperature sterilization furnace to sterilize the load bag filled with materials at high temperature, and the existing problems are: [0004] The high-temperature steam is transported from the steam source to the bottom of the h...

AI Technical Summary

Problems solved by technology

[0004] The high-temperature steam is transported from the steam source to the bottom of the high-temperature sterilization furnace through pipelines. The outlet position of the high-temperature steam at the bottom of the high-temperature sterilization furnace is fixed, which leads to uneven distribution of high-temperature steam in the high-temperature sterilization furnace, resulting in high temperature The edible fungus cultivation material bag in the sterilization furnace is not sterilized evenly, which affects the subsequent cultivation of edible fungi

In addition, too high stacking of material bags also leads to low sterilization efficiency
