けられる。 A convection guiding cylinder is provided inside the cylindrical container 3, and the convection guiding cylinder is inclined in a funnel shape so that the angle α between the convection guiding cylinder upper part 1 and the convection guiding cylinder main body 2 is 75° to 115°. A turbine blade 4 and an inclined paddle blade 5 are provided inside the convection induction cylinder and are rotated by a motor 6 . Further, the inner wall of the cylindrical container 3 is provided with a baffle plate 7, an air inlet pipe 8, a spargeer 9 at the tip thereof, and an air outlet pipe at the top.

導円筒本体２とのなす角度αが75゜〜115゜である
対流誘導円筒は知られていなかつた。 Conventionally, some fermentation apparatuses have been equipped with a convection induction cylinder for the purpose of promoting mixing of the liquid medium and making the liquid medium uniform during culturing of microorganisms. However, in conventional convection guide cylinders, the angle α between the convection guide cylinder upper part 1 and the convection guide cylinder main body 2 is in the range of 0° to 45°. Further, as seen in Japanese Utility Model Publication No. 27-10391, an inverted cone-shaped convection induction cylinder is known, but the angle α between the convection induction cylinder upper part 1 and the convection induction cylinder main body 2 as in the present invention is 75°. A convection-inducing cylinder with an angle of ~115° was unknown.
従来の対流誘導円筒を用いた発酵装置は、撹拌
をしていない状態では液体培地の液面が対流誘導
円筒の上部になるようにして通気撹拌培養され
る。 In a conventional fermentation apparatus using a convection induction cylinder, aeration and agitation cultivation is performed so that the liquid level of the liquid medium is at the top of the convection induction cylinder when stirring is not performed.
一方、本考案の発酵装置を用いる際は、撹拌を
していない状態では液体培地の液面が対流誘導円
筒上部１より下部にあるようにし、通気撹拌培養
しているときには液体培地は対流誘導円筒上部１
より落下し、図１および２に示される矢印の方向
に流動される。 On the other hand, when using the fermentation apparatus of the present invention, the liquid level of the liquid medium should be lower than the convection induction cylinder upper part 1 when stirring is not being performed, and when the aeration and agitation culture is being carried out, the liquid medium should be placed in the convection induction cylinder. Upper part 1
1 and 2, flowing in the direction of the arrows shown in FIGS. 1 and 2.
本考案の発酵装置を用いると、液体培地は対流

器３の上部の気体との接触面が大きくなる。従つ
て、従来の発酵装置よりも液体培地の溶存酸素量
が多くなり微生物の増殖が非常に促進される。 When the fermentation apparatus of the present invention is used, the liquid medium falls from the upper part 1 of the convection induction cylinder, so that the contact surface between the liquid medium and the gas at the upper part of the container 3 becomes large. Therefore, the amount of dissolved oxygen in the liquid medium is greater than in conventional fermentation equipment, and the growth of microorganisms is greatly promoted.
また、本考案の発酵装置を用いると液体培地の
混合が促進され均一となり溶存酸素量も多くな
り、さらに液体培地が対流誘導円筒上部１より落
下する際に消泡効果があることが見出された。 In addition, it has been found that when the fermentation apparatus of the present invention is used, the mixing of the liquid medium is promoted and becomes uniform, and the amount of dissolved oxygen is increased, and furthermore, it has an antifoaming effect when the liquid medium falls from the upper part 1 of the convection induction cylinder. Ta.
本考案の対流誘導円筒上部１は平面的な漏斗状
でもよいが、穴を開けたり、切れ込みを入れたり
して液体培地と培養槽上部の気体との接触面を大
きくすることによつて、微生物の増殖をさらに促
進させることができる。 The convection induction cylinder upper part 1 of the present invention may have a flat funnel shape, but by making holes or making cuts to increase the contact surface between the liquid medium and the gas at the top of the culture tank, it is possible to The proliferation of can be further promoted.
