Problems solved by technology

Due to these reasons, the production efficiency of laundry soap powder is low, the energy consumption per ton of product is high, and the product is easy to yellow, etc.
[0005] On the other hand, after being sprayed by the high tower, the sodium fatty acid in the slurry volatilizes to a certain extent, and the volatilized part enters the exhaust gas dust removal system and adheres to the inner wall of the dust removal system, reducing the efficiency of the dust removal system and increasing the dust removal system. The difficulty of cleaning; at the same time, due to the volatilization loss of the fatty acid sodium component, the active ingredients in the soap powder product are reduced, and the detergency of the product is reduced to a certain extent

Embodiment 1

[0026] Such as figure 1 Shown, a kind of method utilizing high tower spray drying to prepare fragrant fruit oil soap powder, step comprises:

[0027] (1) 24.76 parts by weight of wild xiangguo oil was saponified with 7 parts by weight of liquid sodium hydroxide in a reaction pot equipped with a stirrer and open steam, and the wild natural xiangguo oil was removed by saponification and salting out twice. Impurities and pigments, and then through two alkali analysis and one finishing to obtain a pure soap base with a fatty acid content of more than 60%;

[0028] Wherein, the salting-out is to add brine to wash, and stand for 3 hours.

[0029] Wherein, each alkali analysis operation time is 3 hours, and the static time is 3 hours. During the preparation process, precautions should be taken: 1) The requirements for alkali analysis are gradually reduced to ensure the purity of the soap base; 2) After each alkali analysis, the soap particles are required to be boiled before turnin...

Embodiment 2

[0035] Such as figure 1 Shown, a kind of method utilizing high tower spray drying to prepare fragrant fruit oil soap powder, step comprises:

[0036] (1) 24.76 parts by weight of wild xiangguo oil was saponified with 7 parts by weight of liquid sodium hydroxide in a reaction pot equipped with a stirrer and open steam, and the wild natural xiangguo oil was removed by saponification and salting out twice. Impurities and pigments, and then through two alkali analysis and one finishing to obtain a pure soap base with a fatty acid content of more than 60%;

[0037] Wherein, salting-out is to add brine to wash, stand still for 3.5 hours.

[0038] Wherein, each alkali analysis operation time is 3.5 hours, and the static time is 3.5 hours.

[0039] Among them, the finishing operation time is 3.5 hours, and the rest time is 26 hours.

[0040] (2) Put 35 parts by weight of soap base into a reaction kettle containing a stirrer, add appropriate amount of water and 6.2 parts by weight o...

Embodiment 3

[0044] Such as figure 1 Shown, a kind of method utilizing high tower spray drying to prepare fragrant fruit oil soap powder, step comprises:

[0045](1) 24.76 parts by weight of wild xiangguo oil was saponified with 7 parts by weight of liquid sodium hydroxide in a reaction pot equipped with a stirrer and open steam, and the wild natural xiangguo oil was removed by saponification and salting out twice. Impurities and pigments, and then through two alkali analysis and one finishing to obtain a pure soap base with a fatty acid content of more than 60%;

[0046] Wherein, salting-out is to add brine to wash, stand still for 4 hours.

[0047] Wherein, each alkali analysis operation time is 4 hours, and the static time is 4 hours.

[0048] Among them, the finishing operation time is 4 hours, and the rest time is 28 hours.

[0049] (2) Put 35 parts by weight of soap base into a reaction kettle containing a stirrer, add appropriate amount of water and 6.2 parts by weight of liquid ...

Abstract

The invention relates to the production field of chemical products for daily life and particularly relates to a method for preparing lindera communis hemesl oil soap powder through spray drying of a high tower. The method comprises the steps of carrying out mixed reaction on a neat soap and a washing assistant; grinding; standing and ageing; carrying out spray drying; cooling by virtue of cold air; carrying out air delivery; and aging and screening to obtain a finished product. Due to the application of a technology for drying soap powder through spray drying of the high tower, the mindset that the soap powder can only be prepared by using an agglomeration forming process is broken, the defects that soap powder formed through agglomeration is solid in particle and small in apparent specific gravity and is not easily dissolved are overcome, meanwhile, the problem that effective substances are lost at high temperature is solved, and the hollow and uniform granulated soap powder which is good in washing effect and good in flowability and is extremely easily dissolved into water is produced. The lindera communis hemesl oil soap powder is a natural product and is strong in detergency, free of phosphorus, capable of saving power and water and protecting the skin and easy to bleach and wash. Due to the popularization of the lindera communis hemesl oil soap powder, the discharged sewage can be greatly reduced, the practical significance for accelerating the establishment of an environment-friendly and economical harmonious society is far-reaching, and the application prospect is significant.

Description

technical field [0001] The invention relates to the production field of daily-use chemicals, in particular to a method for preparing fragrant fruit oil soap powder by spray drying in a high tower. Background technique [0002] The raw materials of fatty acid sodium in laundry soap powder products are derived from animal and vegetable oils, which are renewable resource raw materials. The laundry soap powder produced by using sodium fatty acid as a raw material to partially replace the petroleum-based surfactant in washing powder products is mild and non-irritating to hands; it is easy to rinse. Compared with general washing powder products, rinsing can save about 30% of water. Therefore, laundry soap powder product belongs to the laundry product of green environmental protection type, is deeply liked by consumers in general. [0003] When producing laundry soap powder, the raw materials of sodium fatty acid used are: powdered sodium fatty acid, granular sodium fatty acid and...
