Problems solved by technology

The soy protein in vegetable protein is rich in a large amount. At present, the protein in soybean protein is generally extracted from soybean meal, but from the prior art, it has the following disadvantages: (1) using traditional alkali-soluble acid precipitation In order to ensure the extraction rate and resource reuse rate, people have developed multiple extraction and multiple separation methods, but the occupancy rate of the equipment has been greatly increased, which not only increases the purchase cost of the equipment, but also greatly improves the equipment cost. (2) Although soybean meal contains very little fat, the residual oil rate in different soybean meal is different according to the source of soybean meal. Generally, the residual oil rate is 0.63-1.89%, while the combination of fat and soybean protein It is difficult to extract protein when they are together, and for large enterprises, the loss caused by a 1% reduction in protein extraction rate is also very large; in view of the above shortcomings, it is necessary to design and develop a high-efficiency soybean meal protein extraction equipment and method, which can Make up for the above-mentioned shortcomings

Embodiment 1

[0037] Such as Figure 4 As shown, the present invention also discloses a high-efficiency soybean meal protein extraction method, which is specifically as follows:

[0038] (1) Primary leaching: add water and soybean meal to the tank A1 in a ratio of 8-9:1 for mixing, and add NaOH solution to it to adjust the pH to 8-8.3, and then stir under the stirring rod 5 Soak for 5-20 minutes, at this time the temperature is controlled at 25-30°C;

[0039] (2) Separation: The liquid that has been leached once is transported to the separator A8 through the catheter tube 7 for separation. At this time, the valve A15 and the valve C19 are opened, so that the separated liquid can be separated from the clear liquid discharge pipe A16 and the infusion pipe. 18 flows in the aftertreatment tank 28, the solid phase thing that makes separation continue to flow in the tank body A1 from the solid phase thing discharge pipe A14;

[0040] (3) Secondary leaching: mix water and solid phase at a ratio ...

Embodiment 2

[0052] (1) Primary leaching: add water and soybean meal to the tank A1 at a ratio of 9 to 11:1 for mixing, and add NaOH solution to it to adjust the pH to 8.3 to 8.7, and then soak under the stirring of the stirring rod 5-20min, at this time the temperature is controlled at 30-35°C;

[0053] (2) Separation: The liquid that has been leached once is transported to the separator A8 through the catheter tube 7 for separation. At this time, the valve A15 and the valve C19 are opened, so that the separated liquid can be separated from the clear liquid discharge pipe A16 and the infusion pipe. 18 flows in the aftertreatment tank 28, the solid phase thing that makes separation continue to flow in the tank body A1 from the solid phase thing discharge pipe A14;

[0054] (3) Secondary leaching: mix water and solid phase at a ratio of 4.8 to 5.4:1, and continue to add NaOH solution to tank A1 to adjust the pH to 8.3 to 8.7, and then stir it under the stirring rod 5 Soak for 5-20 minutes,...

Embodiment 3

[0065] (1) Primary leaching: Add water and soybean meal to the tank A1 in a ratio of 11-12:1 for mixing, and add NaOH solution to it to adjust the pH to 8.7-9, and then soak under the stirring of the stirring rod 5-20min, at this time the temperature is controlled at 35-40°C;

[0066] (2) Separation: The liquid that has been leached once is transported to the separator A8 through the catheter tube 7 for separation. At this time, the valve A15 and the valve C19 are opened, so that the separated liquid can be separated from the clear liquid discharge pipe A16 and the infusion pipe. 18 flows in the aftertreatment tank 28, the solid phase thing that makes separation continue to flow in the tank body A1 from the solid phase thing discharge pipe A14;

[0067] (3) Secondary leaching: mix water and solid phase at a ratio of 5.4 to 6:1, and continue to add NaOH solution to tank A1 to adjust the pH to 8.7 to 9, and then stir under the stirring rod 5 Soak for 5-20 minutes, at this time ...

Abstract

The invention discloses a high-efficiency soybean meal protein extraction device and method. The extraction device mainly comprises: a tank body A and a tank B which are arranged in parallel; a centrifuge A and a centrifuge B which are symmetrically arranged at the upper ends of the tank body A and the tank body B correspondingly; and a post-treatment tank arranged at the side edges of the tank body A and the tank body B. One part of the high-efficiency soybean meal protein extraction device is used for extraction, the other part is used for hydrolysis, and the two parts can be repeatedly used multiple times as demanded, so the protein extraction efficiency is improved, and the occupied area and the purchasing cost of the device are reduced. The high-efficiency soybean meal protein extraction method comprises two-time extraction and two-time hydrolysis, the extraction mainly uses an alkali dissolution technology, and the two-time extraction guarantees the protein extraction rate and reduces the waste of a liquid obtained after separation; and the hydrolysis is mainly used for separating a small amount of proteins combined with fats in soybean meal, so the protein extraction rate is effectively improved.

Description

technical field [0001] The invention relates to a plant extraction equipment and method, in particular to a high-efficiency soybean meal protein extraction equipment and method. Background technique [0002] Protein is a biological macromolecular substance necessary for living organisms. It is the macromolecular substance with the most abundant content and the most functions in cells. It plays an important role in various life activities and is the material basis for sustaining life. The Food and Agriculture Organization of the United Nations (FAO) stated that adults should consume more than 75g of protein per day, while the world's average level is only 68.8g, and my country's current average level is only 60g. Insufficient protein intake is mainly caused by insufficient absolute intake of protein and the imbalance of amino acids in the protein intake. At present, the primary method to solve insufficient protein intake is to develop new protein sources and solve amino acid ...
