Embodiment

[0019] Step 1: Cool the water used in the production process of soybean protein isolate to 5°C through chiller equipment;

[0020] Step 2: using the process cooling water described in step 1 to directly add to the soybean protein isolate curd to cool down the curd to 20°C with a solid content of 15%;

[0021] Step 3: Use the process cooling water described in step 1 to pass into the plate heat exchanger, so that the initially cooled curd thinner liquid is cooled through the plate heat exchanger, and the material is cooled to 15°C, and then the material is pumped into the neutralization in the tank;

[0022] Step 4: Pass the process cooling water described in step 1 into the interlayer of the neutralization tank for circulating refrigeration, keep the temperature of the neutralization tank at about 15°C, then the temperature of the neutralization liquid can be maintained at 15°C.

Abstract

The invention discloses an online temperature-reducing cooling process for production of soybean protein isolate. The process cooling water is process water in a workshop and is cooled to 2-20 DEG C via a refrigeration device (cooling-water machine); after the acid-precipitation process for the production line of the soybean protein isolate, in the centrifugally separated protein coagulation, if the process cooling water is directly mixed with the soybean protein coagulation, the coagulation is cooled for temperature reduction, and the coagulation after the preliminary temperature reduction is cooled through a plate type heat exchanger for cooling via the process cooling water; and then the coagulation is pumped into a neutralization tank, and the cooling water with the temperature of 2-20 DEG C is introduced into the sandwich layer of the neutralization tank for constant temperature control.

Description

technical field [0001] The invention relates to a soybean protein isolate production process, in particular to the soybean protein isolate production process of the online cooling process. Background technique [0002] At present, there is no temperature control system in the process of producing protein isolates in various enterprises, which causes the temperature of the materials in the entire production line, especially the temperature of the materials in the neutralization tank, to change with the temperature of the environment throughout the year, making soybeans The product quality of protein isolates fluctuates with temperature. Contents of the invention [0003] The purpose of the present invention is to provide an online cooling process for the production of soybean protein isolate in order to avoid the above-mentioned shortcomings. [0004] The present invention is achieved like this: [0005] The on-line cooling process for the production of soybean protein is...
