Embodiment 1

[0016] 1. The cassava distiller's residue liquid is recovered in the sedimentation tank, and the measured pH value is approximately equal to 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% polyaluminium chloride of its weight to the dross liquid of step (2), stir and mix evenly and leave it to stand to make it fully precipitate;

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

[0020] 5. Dehydrate the bottom sediment in step (3) (with 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. The cassava distiller's residue liquid is recovered 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% polyaluminum chloride by weight to the dross liquid in step (2), stir and mix evenly and let stand to make it fully precipitate;

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

[0027] 5. Dehydrate the bottom sediment in step (3) (with 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. The cassava distiller's residue liquid is recovered in the sedimentation tank, and the measured pH value is approximately equal to 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 of step (2), stir and mix evenly and let stand to make it fully precipitate;

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

[0034] 5. Dehydrating 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 lees residue liquid treating method of cassava, which comprises the following steps: 1) collecting the lees residue liquid of cassava in a flow tank and determining the pH value; 2) adding alkali or alkaline substance in (1) to adjust the pH value of lees residue liquid of cassava to 6 to 9; 3) adding destabilization coagulant agent of polyaluminium chloride or/and polyferric sulfate with the amount of 0.0015 to 0.003% of the lees residue of cassava, and stirring uniformly, and then standing; 4) removing the pelagic water liquid in the mid-upper layer; 5) dehydrating the sediment in the middle and bottom layers of 3); 6) drying and crushing the dehydrated sediment to obtain the finished product of lees powder. The invention has the advantages that the lees residue liquid which comes from making wine, extracting starch or extracting citric acid with cassava, is quickly treated with rational technology, simple and easy production method and cheap and easy-getting raw materials; the useful components such as such as starch, crude fiber, calcium, trace minerals, crude protein, and crude fat, which are remained in the lees residue liquid as waste, are effectively recovered; top-quality feedstuff or feedstuff material is provided for the society, and the waste is reused, waste discharge is reduced; the pollution of water source, water body and peripheral environment is eliminated or effectively controlled.

Description

technical field [0001] The invention relates to the technical field of agricultural by-product processing, in particular to a method for processing cassava distiller's residue liquid, tapioca starch residue liquid or cassava citric acid residue liquid. Background technique [0002] The agricultural product of cassava is 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 which cassava is used as Alcohol brewing from raw materials is an earlier and most widely developed project, and its technology is very mature. In recent years, cassava has been widely used to extract starch and citric acid. However, using cassava as a raw material, whether it is brewing alcohol or extracting starch and citric acid, etc., there will be a huge amount of dregs. However, according to the detection and analysis, it is known that the unutilized starch is ab...
