圆盘式固态发酵器生产单细胞蛋白的研究

Study on Rotary-tray Fermenter for Solid State Culture Applying the Single Cell Protein Production

采用圆盘式固态发酵器生产单细胞蛋白。发酵器有机械化上料，搅拌、补料、出料装置和自动调节温度、湿度、通风系统，单机日产量１吨，用ＳＣ８５和ＳＴ８５１酵母以淀粉质原料，固态培养２４ｈ，产品粗蛋白含量由１５．７％增加至４０．５０％以上（以干物质计），蛋白酸含量接近鱼粉。该工艺培养条件稳定，产品质量可靠，表明圆盘式固态发酵器是一种性能良好的发酵器。

A rotary-tray fermentor for solid state fermentation(SSF) has been studied to produce the single cell protein(SCP). The equipment has mechanical input, agilation, output device and feeder. The temperature and relative humidity were regulated by an automatic control system. It having a maximum working capacity of one ton can be scaled up to the production plant level. This equipment for SSF has been used for SCP production on raw starchy material with SC_(85) and ST_(851). During the processes the protein content increases from 15.7 to 40.7% for 24h. The product quality was stable.
