Oxygen supply device for needle mushroom breeding room

Abstract

The invention discloses an oxygen supply device for a needle mushroom breeding room, which comprises two fresh air inlet pipes communicated with an outlet pipe of a blower. Each inlet pipe is provided with air outlet holes and disposed above a mushroom bed. The oxygen supply device is characterized in that the fresh air inlet pipes in parallel are disposed above the mushroom bed, one end of one inlet pipe and one end of the other inlet pipe are respectively communicated with the outlet pipe of the blower, and the other end of one inlet pipe and the other end of the other inlet pipe are communicated with a condensate outflow pipe. During production, fresh air is horizontally blown to diffuse to two interior sides of the mushroom room and is also vertically blown to the mushroom bed below the pipes, so that flowing of the fresh air in the mushroom room is uniform, and growth and development requirements of mushrooms are met.

Description

technical field [0001] The invention relates to the cultivation of edible fungi, in particular to the cultivation of Flammulina velutipes among the edible fungi. Background technique [0002] Flammulina velutipes has health functions such as rich nutrition, delicious taste, invigorating spleen and Qi, and improving immunity. It can effectively enhance the physiological activity of the body, promote metabolism in the body, and is beneficial to the absorption and utilization of various nutrients in food. Because Flammulina velutipes has a high zinc content, it has the effect of promoting children's intellectual development and strengthening the brain. Therefore, it is known as "educational mushroom" or "increasing wisdom mushroom" in many countries such as Japan. Regular consumption of Flammulina velutipes can not only prevent and treat liver disease and stomach and intestinal ulcers, but also is suitable for hypertensive patients, obese people and middle-aged and elderly peop...

AI Technical Summary

Problems solved by technology

The fresh air input pipe is generally installed horizontally above the mushroom bed in the breeding room (one end is connected to the blower, and the other end is a blind pipe). There are several air outlets on the two side walls of the pipe. The defects of this arrangement are: 1. Because the fresh air contains moisture, there is condensed water in the horizontally arranged pipes all the year round, which is easy to breed bacteria in the pipes, and the air blown into the breeding room contains more water, which increases the humidity in the growing room, which is not good. Conducive to the growth of Flammulina velutipes

2. In order to prevent the condensed water in the pipe from flowing out, the air outlet can only be set on the two side walls of the pipe, resulting in fresh air being blown to both sides, and the mushroom bed directly under the pipe gets less fresh air

3. Flammulina velutipes growth chambers are generally equipped with four rows of mushroom beds, one row on each side, and two rows in the middle (there is a passage between the two sides and the middle mushroom bed). Each row of mushroom beds has 5-10 layers. Existing In technology, there is usually only one air input pipe (all above the uppermost mushroom bed). Although there is a circulating blower in the mushroom house, it is difficult to blow fresh air evenly to any corner of the mushroom house. As a result, where the supply of fresh air is sufficient, Flammulina velutipes grows well and grows fast. On the contrary, it grows poorly and grows slowly, which not only affects the quality of the mushrooms, but also affects the economic benefits of the enterprise.
