Soybean protein concentrate production system

Abstract

The invention relates to a soybean protein concentrate production system. The production system is characterized in that a wet meal outlet of an extractor is connected with an inlet of a wet meal conveyor; an outlet of the wet meal conveyor is connected with a feeding opening of a double-spiral dry squeezing machine; a discharging opening of the double-spiral dry squeezing machine is connected with a feeding opening of a first horizontal drying machine; a discharging opening of the first horizontal drying machine is connected with an inlet of a hot meal scraping plate conveyor; an outlet of the hot meal scraping plate conveyor is connected with a feeding opening of a second horizontal drying machine through an air closing feeder; a discharging opening of the second horizontal drying machine is connected with a feeding opening of a cyclone dust collector (Shakelong) through an air closing discharging device; an air exhaust opening of the cyclone dust collector is connected with an inletof an induced draft fan; a rotary discharging valve is mounted at the bottom of the cyclone dust collector; an air phase discharging opening of the second horizontal drying machine is connected withan inlet of a vacuum condenser; an air phase outlet of the vacuum condenser is connected with an air extraction opening of a steam jet pump; a steam inlet of the steam jet pump is connected with a main steam pipe. The soybean protein concentrate production system has the advantages that the defect of food grade protein concentrate thermal denaturation can be overcome; the economic value is improved.

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
