Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural planting device technical field, concretely is the second fermentation tunnel of double spore mushroom culture medium. BACKGROUND

[0002] Double spore mushroom is a kind of edible fungus with delicious taste, large cultivation scale and wide cultivation range;Its protein content is as high as 42%, rich in amino acids, nucleotides and vitamins and other nutrients, and double spore mushroom has been widely cultivated in China. The culture medium of cultivated double spore mushroom is widely fermented by rice straw, straw and other materials, and is packed after being broken. The forage is usually fermented for several times, and the second fermentation is carried out again on the basis of the first fermentation. After the second fermentation, the culture medium can be fermented more thoroughly, the nutrient content of the culture medium is greatly improved, and the harmful substances such as insect eggs and miscellaneous bacteria in the culture medium are killed, so as to improve the yield and quality of double spore mushroom.

[0003] Usually, the second fermentation of culture medium is carried out in a tunnel-shaped fermentation bin. The culture medium is stacked in the tunnel, and usually goes through several stages: first, the culture medium is pasteurized by using high-temperature steam, then fermented at medium temperature, and finally cooled after leaving the bin, which completes the second fermentation. However, the existing second fermentation tunnel still has the following shortcomings: 1. The steam sterilization of the culture medium is not thorough enough, and the core of the culture medium stack is often not completely sterilized, and residual miscellaneous bacteria still exist;2. The ammonia gas produced by microorganisms during fermentation is not discharged in time, which affects the fermentation effect;3. The tunnel control is not automatic and intelligent enough, and manual control is required frequently. SUMMARY

[0004] The utility model aims at providing a kind of double spore mushroom culture medium second fermentation tunnel, with the advantages of complete function, realize double spore mushroom culture medium second fermentation whole process automatic and intelligent operation, save a lot of manual work;The fermented culture medium is uniform in quality, harmful substances such as miscellaneous bacteria and parasitic eggs are completely removed, and it is rich in nutrients, suitable for large-scale double spore mushroom planting enterprises to use.

[0005] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] Double spore mushroom culture medium second fermentation tunnel, one side of the tunnel is provided with a steam main pipe, the steam main pipe branches out several steam branch pipes, the end of the steam branch pipe extends into the bottom of the tunnel and is connected with a gas outlet groove, and the gas outlet groove is a longitudinal recess in the bottom surface of the tunnel.

[0007] Steam from the steam main pipe into the steam branch pipe, each steam branch pipe with several gas slot bottom gas hole connected, high temperature steam from the long slot along the entire length of the tunnel upward transpiration, steam into the corners and crevices of the material, keep 60-65 DEG C pasteurization temperature, effectively kill the bacteria and parasitic eggs in the base material everywhere, compared with the traditional greenhouse simple heating and humidification processing, kill more thoroughly, kill faster, energy saving.

[0008] The steam branch pipe is provided with a one-way valve.

[0009] The tunnel top surface is provided with a plurality of air inlets and air outlets, the air inlets are connected with the fan through air inlet pipes, and the air outlets are connected with the ammonia gas absorber through air outlet pipes.

[0010] During the fermentation stage of the base material in the tunnel, the fermentation bacteria in the base material will produce a large amount of ammonia gas, and too much and too thick ammonia gas will affect the fermentation effect, so that the ammonia gas in the tunnel is discharged in time; at the same time, the fermented material will produce a large amount of heat, in order to maintain a constant fermentation temperature, the air flow and ventilation of the material need to be appropriately carried out; fresh cold air is sucked from the filter screen of the fan, enters the tunnel cavity from the air inlet at the head of the tunnel, and the humid hot air and ammonia gas in the tunnel are discharged from the air outlet and enter the ammonia gas absorber for absorption, and then can be discharged to the atmosphere to prevent air pollution; the ammonia gas absorber is provided with activated carbon, calcium chloride and calcium hydroxide to absorb the ammonia gas.

[0011] The air inlet pipe is provided with an air inlet valve.

[0012] The air outlet pipe is provided with an air outlet valve.

[0013] The tunnel is also provided with an ammonia gas on-line detector, a temperature and humidity meter and an oxygen on-line detector, which are connected with the PLC through signal cables, and when the parameters exceed the preset values, the corresponding equipment is started to work to control the environment in the tunnel.

[0014] The tunnel is also provided with an ammonia gas on-line detector, a temperature and humidity meter and an oxygen on-line detector, which are connected with the PLC through signal cables, and when the parameters exceed the preset values, the corresponding equipment is started to work to control the environment in the tunnel.

[0015] Advantages of the utility model

[0016] (1) The utility model discloses can realize the full -automatic intelligent production of the whole process of the secondary fermentation of agaricus bisporus, saves manual work, and control accurate, and the medium quality of fermentation is even, and harmful substance such as miscellaneous bacteria and parasitic worm egg is removed thoroughly, and it is rich in nutrition, and it is suitable for the use of agaricus bisporus enterprise of large -scale planting.

[0017] (2) The utility model discloses in the steam pasteurization stage, compared with the simple heating and humidification treatment in the traditional greenhouse, the killing is more thorough, and the killing speed is faster, and energy is saved. BRIEF DESCRIPTION OF DRAWINGS
