Problems solved by technology

[0002] In the vegetable oil factory, the soybean meal after degreasing by leaching method contains about 30% wet meal. For the desolvation of wet meal, the traditional soybean leaching workshop only uses high temperature desolventization, and the product obtained is only high temperature meal, and the soybean protein is variable. High degree, can not be used in food grade field
In the traditional low-temperature meal production line, due to the imperfection of the development and research of the low-temperature desolventizer, as well as the control of the temperature and vacuum degree during the desolventization, and the realization of energy-saving utilization, there are some uncontrollable factors, so the low-temperature desolventization is generally independent. production line, and the production volume is not large

Embodiment Construction

[0007] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] Depend on figure 1 Provide, the present invention is realized by the following steps in concrete implementation: at first install equipment, the installation of equipment is, extractor 1 is respectively provided with soybean germ sheet inlet, n-hexane import, two outlets of extractor are respectively connected with The wet meal scraper 2 is connected to the evaporator 8, and the wet meal scraper 2 is connected to the high-level storage box 3. There are two symmetrically arranged wet meal outlets on the storage box 3, and one outlet A is the same as the high-temperature twisting Dragon 4 is connected, and the other outlet B is connected with low-temperature auger 5, high-temperature auger 4 is connected with high-temperature desolventizer 6, low-temperature auger 5 is connected with low-humidity desolventizer 7, and high-t...

Abstract

The invention relates to a method for simultaneously continuous stable production of soybean leached wet meal through two different production lines of high-temperature desolvation and low-temperature desolvation. The method can be used for effectively solving the problem that high-temperature meal and low-temperature meal can be simultaneously produced by using two different production lines in one workshop. The method comprises the steps that solvent-containing soybean meal obtained after soybean embryo flakes are degreased enters an extractor, normal hexane is added for extraction, mixed oil enters an evaporator, the solvent-containing soybean meal enters a storage box, is uniformly broken by using a material distribution stick and then enters a high-temperature auger and a low-temperature auger through a discharge port in the storage box, wet meal entering the high-temperature auger is subjected to desolvation by using a high-temperature desolvation device, wet meal entering the low-temperature auger is subjected to desolvation by using a low-temperature desolvation device, and normal hexane solvent gas coming out of the high-temperature desolvation device, the low-temperature desolvation device and the mixed oil evaporator is respectively condensed and recycled by a high-temperature condenser, a low-temperature condenser and a mixed oil evaporator. The production method is simple, easy to operate and use, low in cost, energy-saving and environmentally-friendly; the ratio of residual oil in the soybean meal is low; the low-temperature soybean meal protein content is ensured.

Description

technical field [0001] The invention relates to food production, in particular to a method for simultaneous continuous and stable production of two different production lines of high-temperature desolventization and low-temperature desolventization of soybean leaching wet meal. Background technique [0002] In the vegetable oil factory, the soybean meal after degreasing by leaching method contains about 30% wet meal. For the desolvation of wet meal, the traditional soybean leaching workshop only uses high temperature desolventization, and the product obtained is only high temperature meal, and the soybean protein is variable. The degree is relatively high and cannot be used in the food-grade field. In the traditional low-temperature meal production line, due to the imperfection of the development and research of the low-temperature desolventizer, as well as the control of the temperature and vacuum degree during the desolventization, and the realization of energy-saving util...
