Description

Technical Field

[0001] The utility model relates to the technical field of mycelium separation, in particular to a double-layer encrypted filtering device used for mycelium separation. Background Art

[0002] ⒉ keto-D-glucarate calcium is an intermediate in the production process of sodium isoVC. During the fermentation process, ⒉ keto-D-glucarate calcium is mixed with mycelium. After the fermentation is completed, the mycelium in the fermentation liquid needs to be separated and removed. The efficiency and quality of the separation directly affect the subsequent synthesis and purification of sodium isoVC products.

[0003] In the prior art, a plate and frame filter is usually used to separate the mycelium. The Chinese utility model patent with publication number CN219652994U proposes a microbial mycelium filtering push-pull device, which is a simplified plate and frame filter. The inner and outer circles of the microbial mycelium filtering push-pull device can slide around along the inner and outer annular grooves to unfold the gauze and block it in the space between the central mounting plate and the outer support ring for filtering and extraction. The two T-shaped sliders welded together by the connecting support plate are welded and fixed together with the rotating circle by an L-shaped connecting rod, and the rotating circle is welded and fixed together with the vertical connecting shaft and the screwing ring. Then, the gauze can be driven to rotate and compress along the two annular grooves by reversing the screwing ring to squeeze out the excess liquid culture medium adsorbed on the gauze. Compared with direct manual squeezing, this can avoid contamination of the mycelium on the gauze and ensure the accuracy of the experimental data.

[0004] However, due to the pore size limitation of the single-layer gauze, the mycelium separation of the above-mentioned device is not efficient enough during use, and abnormal phenomena such as low transmittance of the filtrate and material escape often occur, resulting in increased sewage discharge, waste of raw materials and increased energy consumption during the production process.
