Process for continuously preparing bacterial cellulose

Process for the production of bacterial cellulose

A method for the production of a bacterial cellulose by cultivating a cellulose-producing bacteria for at least a certain period of time under such an apparatus condition that an oxygen-transfer coefficient (K.sub.L a) is about 25 to about 50/hr, said K.sub.L a is determined by using a simulated suspension containing 2% by weight of BC and having a plastic viscosity of 15 to 20 poise.

Method for cultivating apparatus for the production of bacterial

The present invention relates to a fragrant air supplying method, supplying apparatus, and a building having a fragrant air supplying system for supplying fragrant air to the rooms. A fragrant-material supplying means supplies fragrant material to a mist-generating means to generate mist either by blowing air or by vibration produced by an ultrasonic-oscillating means. The mist is blown to a surface portion formed at the end of a fragrant-air separating means which separates evaporated fragrant air from mist. The fragrant air is then introduced into holes formed in a fragrant-air discharging means, in which the place of holes are offset from the surface portion toward the downstream of the fragrant air. The fragrant air is then blown into a distributing passage from the fragrant-air discharging means to mix the fragrant air with conditioned-air supplied by an air-supplying means. This makes fragrance-mixed air for distributing to a predetermined space or rooms for the physical and mental activation of the human body.

Fragrant air supplying method and supplying system

The present invention pertains to an ultrasonic fragrance generation apparatus for buildings, vehicles, aircraft, and the like, as well as for open areas. In particular it pertains to an ultrasonic fragrance generation apparatus by which means a suitable fragrance may be dispersed into the ambient air at a suitable time in the optimum concentration. By employing a material having increased surface area on the ultrasonic vibrating surface, it is possible with the present invention to generate a fragrant mist at an increased rate.
