Plate and frame filter-pressing method for improving oven dry efficiency factor of thalli protein

The invention discloses a sheet frame press filter process for improving drying efficiency of bacterial protein. Firstly, flocculating agent is added into the glutamate high concentration wastewater; secondary, the bacterial protein is extracted through air floatation, and finally, the bacterial protein is entered into a temporary storage tank. The sheet frame press filter process is characterized in that the vapor is pumped into the temporary storage tank to be processed pre-treatment so that the temperature of the temporary storage tank is heated up to 85-100 centigrade. Then the frame press filter process is carried out, and the intermediate products with the water containing of 45 percent is obtained. The intermediate products are dried under the temperature of 850 centigrade. The bacterial protein products can be obtained after being crushed, sieved and packaged. Comparing with the traditional process, the sheet frame press filter process has the beneficial effects that because the ...
