Extracting and energy-saving system for L-tryptophan membrane

Abstract

The invention discloses an extracting and energy-saving system for L-tryptophan. The system comprises a fermentation liquid storage tank, a ceramic membrane filter and a clear liquid tank which are sequentially connected by virtue of a pipeline, wherein the fermentation liquid storage tank is connected with a dialysis water adding device and is further provided with an L-tryptophan concentration detection opening; the ceramic membrane filer is provided with a controller which is used for controlling operation of the filter according to concentration of L-tryptophan. The bottom of the fermentation liquid storage tank is further connected with a mushroom dreg tank by virtue of a centrifugal pump, the mushroom dreg tank is internally filled with a flocculation agent and is communicated with the plate-and-frame filter press by virtue of the mushroom dreg tank, and a filtrate discharge pipe of the plate-and-frame filter press is connected and communicated with the top of the fermentation liquid storage tank. The system can be used for effectively shortening the operating time of the ceramic membrane, improving the tank-loading batch for fermentation, lowering the production cost and reducing the quantity of wastewater effluent.

Description

technical field [0001] The invention belongs to the field of amino acid extraction equipment, and mainly relates to an energy-saving system for L-tryptophan membrane extraction. Background technique [0002] At present, the extraction of tryptophan is limited by the low acid production per unit, and the large impurities in the fermentation broth are difficult to extract. Therefore, the post yield is very important. To ensure the yield of the ceramic membrane, it is necessary to add a large amount of dialysis water for dilution, resulting in a longer running time of the ceramic membrane. It is long, which restricts the batches of fermentation tanks. At the same time, the membrane is seriously polluted and it is difficult to clean thoroughly, and the sewage discharge is large. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving system for L-tryptophan membrane extraction, which can effectively reduce the The operating tim...
