Problems solved by technology

The above method has the following defects. The one is that there is little water coming out, and the other is that after centrifugal dehydration and drying, the obtained dregs are colloidal particles that are dry on the outside and wet on the inside. few

Embodiment 1

[0016] 1. Recover the green plum distiller's grains liquid in the sedimentation tank, and the measured pH value is about 5;

[0017] 2. Stir and gradually add CaO to adjust the pH value to 6 (the amount added is about 0.15% of the weight of the bad residue liquid);

[0018] 3. Add 0.002% polyaluminum chloride by weight to the dross liquid in step (2), stir and mix evenly, and let stand to make it fully precipitate;

[0019] 4. Drain the upper clear water in step (3);

[0020] 5. Dehydrate the bottom sediment in step (3) (using a dehydrator) to obtain a bad body with a water content of about 30%;

[0021] 6. Dry and pulverize the bad body obtained in step (5) to obtain the finished bad powder.

Embodiment 2

[0023] 1. Recover the greengage distiller's grains liquid in the sedimentation tank, and the measured pH value is approximately equal to 4;

[0024] 2. Stir and gradually add CaO to adjust the pH value to 9 (about 0.45% of the weight of the bad residue liquid);

[0025] 3. Add 0.0025% polyaluminium chloride by weight to the slag liquid in step (2), stir and mix evenly, and then let stand to make it fully precipitate;

[0026] 4. Drain the upper clear water in step (3);

[0027] 5. Dehydrate the bottom sediment in step (3) (using a dehydrator) to obtain a bad body with a water content of about 30%;

[0028] 6. Dry and pulverize the bad body obtained in step (5) to obtain the finished bad powder.

Embodiment 3

[0030] 1. Recover the green plum distiller's grains liquid in the sedimentation tank, and the measured pH value is about 5;

[0031] 2. Stir and gradually add magnesium hydroxide to adjust the pH value to 6.5 (about 0.2% of the weight of the bad residue liquid);

[0032] 3. Add 0.0015% polyferric sulfate by weight to the dross liquid in step (2), stir and mix evenly, and let stand to make it fully precipitate;

[0033] 4. Drain the upper clear water in step (3);

[0034] 5. Dehydrate the bottom sediment in step (3) with a dehydrator to obtain a bad body with a water content of about 30%;

[0035] 6. Dry and pulverize the bad body obtained in step (5) to obtain the finished bad powder.

Abstract

The invention relates to a method for treating green plum fruit wine vinasse residues and liquor. The method comprises the following steps that firstly, the green plum fruit wine vinasse residues and liquor are recycled in a settling basin, and the pH value of the green plum fruit wine vinasse residues and liquor is measured; secondly, alkali or alkaline matter is added in the settling basin in the first step to regulate the pH value of the green plum fruit wine vinasse residues and liquor to be 6-9; thirdly, destabilizing and settling accelerating agents polyaluminum chloride or / and polyferric sulfate are added with the adding quantity of the desertion stabilizing and settling accelerating agents accounts for 0.0015-0.003% of the plum fruit wine vinasse residues and liquor, and the mixture is evenly stirred and then subjected to standing; fourthly, water liquid on the middle and upper layers is drained; fifthly, bottom layer sediment obtained in the third step is dehydrated; sixthly, the dehydrated sediment is dried and ground, and an end vinasse powder product is obtained.

Description

technical field [0001] The invention relates to the technical field of agricultural by-product processing, in particular to a method for processing greengage distiller's grains liquid. Background technique [0002] Green plum is an agricultural product rich in starch, crude fiber, crude protein and various trace minerals (such as calcium, phosphorus, copper, iron, zinc, selenium), etc., so it is widely developed and utilized by people. Among them, green plum is used as Brewing wine with raw materials is a late and not widely developed project, and its technology is not very mature. However, using greengage as raw material to brew alcohol will produce a huge amount of dregs. For example, an enterprise with an annual output of 10,000 tons of alcohol The annual discharge of slag liquid reaches more than 200,000 tons. However, according to detection and analysis, it is known that these slag liquids still contain about 11.2% of unused starch, about 3.7% of crude fiber, and about ...
