Abstract
The present invention relates to a method for dry fermentation and equipment for carrying out the same. The invention equipment comprises a fermentation tank for dry fermentation which includes a tank body 5 for accommodating materials, a flexible sealing membrane 7 for covering said tank body 5, and a tight fixing means 3 for hermetically covering the tank body 5 with the flexible sealing membrane 7. This invention is characterized in that said tank body 5 is provided with a top opening 2 at its top part and at least one side opening 4 for loading and unloading materials at its side portions. When the tank body 5 is covered hermetically by the flexible sealing membrane 7, said tight fixing means 3 makes the contact area 6 between the tank body 5 and the flexible sealing membrane 7 form at least one sealing contacting strip or at least one sealing line which is continuous and close in three-dimensional space so that the flexible sealing membrane 7 covers hermetically both the top opening 2 and at least one side opening 4 for loading and unloading materials.
