The bottom wall 1 of the heat storage water tank 8 is
It is connected to the opening 89 of No. 0. Further, as shown in FIG. 4, one end of each heat pipe 11 penetrates into the heat exchange tank 87 so as to be alternately overlapped, and the other end projects slightly downward into the fermentation tank 1. In addition, heat pipe 11
The groups are appropriately arranged to the extent that they do not interfere with the operation of the stirring R15.

分調整したものを醗酵熱発生原材料とする。The fermentation chamber of the apparatus configured as described above is filled with a raw material in which rice bran is the main source of acid-acid heat generation. For example, 45 parts of rice bran, 50 parts of mushroom soil slag, and 5 parts of fermentation inducing agent were mixed and the moisture content was adjusted appropriately, or the moisture content was adjusted by mixing 48 parts of rice bran, 40 parts of sawdust, and 12 parts of rice husk with an appropriate amount of fermentation aid. The material is used as a raw material for fermentation and heat generation.

水平回転と同時にその時間帯だけ攪拌装装置１２を例え
ば毎分５〜６回転の割合で駆動させる。The fermentation projector 1 is horizontally rotated at a rate of one rotation per day (for example, it takes about 20 to 30 minutes to complete one rotation), and at the same time as this horizontal rotation, the stirring device 12 is rotated at a rate of, for example, 5 to 30 minutes per minute. Drive at a rate of 6 rotations.

行なわれるのがよい。Fermentation of rice bran is promoted by aerobic microorganisms under conditions of appropriate temperature and humidity, so such stirring can supply oxygen and promote fermentation by equalizing temperature and humidity. Therefore, this stirring is preferably performed occasionally or intermittently.

また、この切り返し・攪拌操作を怠ると黴を生じる恐れ
がある。Moreover, if this turning and stirring operation is neglected, mold may be generated.

また醗酵槽１は、上面が開放状態で且つ開放面積が広く
なるよう逆円錐台形に形成されているので、空気との接
触は一層大きく、醗酵はさらに促進される。Further, since the fermentation tank 1 is formed into an inverted truncated cone shape with an open upper surface and a large open area, contact with air is greater and fermentation is further promoted.

また米糠の醗酵に伴って、植物にとっては必須の成分で
あるＣＯ２が盛んに発生し、いわゆるＣＯ２濃度の上昇
効果のあることが認められた。In addition, it was observed that with the fermentation of rice bran, a large amount of CO2, which is an essential component for plants, is generated, which has the effect of increasing the so-called CO2 concentration.

It becomes. However, when the sun rises and the cucumber's photosynthesis increases, CO in the greenhouse increases! The concentration is about 'isopp
It rapidly decreases to m. Compared to this control area, in the device of the present invention, the highest value of CO2 was 1200 ppm at 6 am.
The lowest value was about 500 ppm at 3:00 p.m. Such an effect of increasing CO2 concentration by the device of the present invention naturally leads to an increase in photosynthesis.

Additionally, the harvest time could be shortened by more than a week. It is presumed that this is due to the effect of 002 etc. generated from the device of the present invention.

○　槽１内の醗酵熱は、ヒートパイプ１１により速やか
に効率良く蓄熱水槽８に移動され放出される。○ The fermentation heat in the tank 1 is quickly and efficiently transferred to the heat storage water tank 8 and released by the heat pipe 11.

米糠を主体とした醗酵原材料中から６０〜７０’（！の
醗酵熱を上部に原材料とは離して設けた水槽８に熱伝導
させるには上記ヒルドパイブ１１が正に最適である。The Hildpipe 11 is ideal for conducting heat transfer of 60 to 70' (!) of fermentation heat from the fermented raw material mainly consisting of rice bran to the water tank 8 provided at the upper part separated from the raw material.

望する温度を確保することができる。As fermentation based on rice bran progresses, the activity of microorganisms slows down, so it is necessary to replenish new fermentation raw materials at appropriate intervals to prevent a drop in fermentation heat and hot water temperature. For example, if new rice bran is applied to the raw material during fermentation three times a month at a rate of approximately 1"a of the original rice bran, and the hopper 84 is replenished deep into the interior through the chute 85, the desired temperature can be maintained for a long period of time. be able to.
