Production system of soybean protein concentrate

Abstract

The invention relates to a production system of concentrated soybean protein. The wet meal outlet of the extractor is connected with the inlet of the wet meal conveyor, and the outlet of the wet meal conveyor is connected with the feed port of a double-screw squeezer. The double-screw squeezer The discharge port of the horizontal dryer is connected with the feed port of the horizontal dryer one, the discharge port of the horizontal dryer one is connected with the inlet of the hot meal scraper conveyor, and the outlet of the hot meal scraper conveyor passes through the closed air feeder It is connected to the feed port of the second horizontal dryer, the discharge port of the second horizontal dryer is connected to the feed port of the Shacron through the closed air discharge device, and the exhaust port of the Shacron is connected to the inlet of the induced draft fan , a rotary discharge valve is installed at the bottom of the Shacron; the gas phase outlet of the horizontal dryer 2 is connected to the inlet of the vacuum condenser, the gas phase outlet of the vacuum condenser is connected to the suction port of the steam jet pump, and the steam of the steam jet pump The inlet is connected to the main steam pipe. This system can solve the defect of heat denaturation of food-grade concentrated protein and improve its economic value.

Description

technical field [0001] The invention relates to an extraction and drying system, in particular to a production system of concentrated soybean protein, which can be used for drying in industries such as food, environmental protection and chemical industry, and belongs to the technical field of soybean processing equipment. Background technique [0002] After leaching (extraction) of low-temperature soybean meal with 70% ethanol aqueous solution, soybean protein concentrate with a protein content (dry basis) of 65-70% can be obtained, and the anti-nutritional substances (such as trypsin, flatulence factor, etc.) Reduced, has the advantages of good palatability, no beany smell, and high digestion and absorption rate. After modification, it can be made into a variety of functional proteins. It has good oil holding, water holding and dispersibility, and can be widely used in bread, ham It can also be used in the fields of sausage and convenience food, and it can also be used in y...

AI Technical Summary

Problems solved by technology

The exhausted steam generated by each heat exchange disc is collected by the collection pipe and must be discharged in time through the outlet pipe. However, there is a bottleneck in this part, which is prone to poor drainage: the outlet of the outlet pipe is small, and it must turn and flow downward. When the water level is low, the drainage is not good. Smooth, when the water level is high, it is too late to drain, resulting in low heat transfer efficiency

[0007] There are too many welds in the outlet pipe, and it is easy to fatigue and open the weld under the action of water hammer and thermal stress, resulting in steam leakage

A small amount of steam leakage will reduce the thermal efficiency of steam

A large amount of leakage will cause production accidents (this equipment is the core equipment of the production line), and once the failure stops, it will cause the entire production line to stop production

[0008] The cost per unit area of ​​the equipment is high (manufacturing cost per square meter is 10,000-12,000 yuan) and the output is insufficient. Blindly increasing the heat exchange area of ​​the equipment leads to large investment, average performance, and mediocre output
