Photosynthetic cultivation fermentation device

Abstract

The invention discloses a material fermentation device, and in particular relates to a photosynthetic cultivation fermentation device, which comprises a tank body with a jacket, a stirring device and illumination devices, wherein the stirring device is fixedly arranged on the upper side of the tank body, a stirring shaft of the stirring device extends into the tank body, more than one stirring blade is arranged on the stirring shaft in an axial direction, the illumination devices are staggered on the tank body along the axial direction of the tank body at intervals, the illumination devices are arranged in a radiation manner from the center of the radial direction of the tank body, and cooling tubes are also arranged in the illumination devices. Due to the adoption of the structure, the defect in the prior art that the illumination devices are arranged in the same plane is overcome, so that illumination is more adequate, the illumination intensity is detected and regulated in real time by a light intensity sensor, and a temperature sensor is used for detecting the interior temperature of the tank body and regulating other parameters. The effect of fog generated in the tank body on the illumination effect is avoided, electricity energy is fully utilized and the resource is saved, the structure is simple, and the fermentation efficiency is effectively improved.

Description

[0001] technical field [0002] The invention relates to a material fermentation device, in particular to a photosynthetic culture fermentation device, which belongs to the technical field of biological fermentation devices. Background technique [0003] At present, the biological reaction technology has been continuously developed, and the control of the biological reaction process has become increasingly complex. From the original simple temperature control, pressure control, pH control, etc. to the control of parameters such as dissolved oxygen and illuminance in the reaction process, the performance of today's photosynthetic reaction equipment has been greatly improved. [0004] At present, the application of photosynthetic culture equipment is still very small, mainly bioreactors made of transparent glass materials. The external light source shines through the glass wall of the reactor to the bacteria inside the reactor, thereby promoting its growth. Due to the limitat...

AI Technical Summary

Problems solved by technology

[0004] At present, the application of photosynthetic culture equipment is still rare, mainly bioreactors made of transparent glass materials, and the external light source shines through the glass wall of the reactor to the The bacteria inside the reactor can promote its growth. Due to the limitation of the light transmittance of the glass material, the light intensity in the fermenter is greatly limited; The color of the culture fermentation liquid is getting darker, and the external light source cannot be irradiated into the fermentation tank, which prolongs the fermentation cycle, makes the growth of photosynthetic bacteria slow, the fermentation product cannot be improved, and the efficiency is low

Patent No. ZL 201120052254.X discloses a photosynthetic culture fermenter, and specifically discloses that several glass tubes in each layer of the lighting device are radially distributed from the radial center of the tank, and only one end of the glass tube is closed and passes through the tank, and the other One end is unconstrained cantilever set in the tank, and the light source is set reasonably, so that the light source can be evenly irradiated into the tank, which not only ensures a large radiation surface, but also does not cause the glass tube to crack even if the tank expands and deforms. However, the disadvantage of this setting is that the light energy is insufficient due to the fog generated during the fermentation process, and the light intensity cannot be adjusted according to the specific environment.
