An apparatus for bioconversion of vegetal raw material comprises a bioreactor communicable with a means for charging this material and discharging the end product. A pressure-sealed chamber for storing excess liquid displaceable from the bioreactor is provided with a liquid level control means and connected to a source of compressed air, atmosphere, inoculator, steam source and bioreactor. A distributor of gas-steam, gas-liquid flows and a flow of inoculum is connected to the liquid level control means and inoculator. Feeders are disposed inside the bioreactor at various levels in terms of height thereof and connected to the flow distributor, a pump being provided between the bioreactor and steam source. A control unit is electrically connected with the bioreactor, steam source, inoculator, compressed air source, a pressure-sealed chamber, flow distributor, and pump. |

DETAILED DESCRIPTION It is therefore an object of the present invention to ensure a uniform heat- and mass-transfer throughout the volume of the bioreactor and, consequently, to improve the efficiency of an apparatus for bioconversion of a vegetable raw material.
The objects of the invention are attained by an apparatus for bioconversion of vegetal raw material comprising a bioreactor communicating with a means for charging this material and discharging the end product, and connected by pipes to an inoculator, a source of compressed air and a source of steam producing gas-steam, liquid-steam flows and a flow of inoculum and electrically connected with a control unit.
According to the invention, the apparatus includes a pressure-sealed chamber for storing excess liquid displaceable from the bioreactor provided with a liquid level control means and connected by a pipe for conveying the gas-steam flows having valves to the source of compressed air, atmosphere, inoculator and the source of steam, and connected by a pipe for conveying the gas-liquid flows having valves to the bioreactor and the source of steam; a distributor of the gas-steam, gas-liquid flows and the flow of inoculum connected by a pipe having a non-return valve to the liquid level control means and by another pipe having a valve to the inoculator; feeders disposed inside the bioreactor at different levels in terms of its height and connected by pipes having valves to the distributor of the gas-steam, gas-liquid flows and the flow of inoculum; a pump for circulating the gas-steam and gas-liquid flows provided between the bioreactor and the source of steam; and, a control unit being connected by its corresponding outputs to the valves provided in the pipes communicating the pressure-sealed chamber with the source of compressed air, atmosphere, inoculator, source of steam and bioreactor, and to the valves provided in the pipes connecting the distributor of gas-steam, gas-liquid flows and the flow of inoculum to the inoculator and feeders, and to the pump
