本発明は、高品質のα−スルホ脂肪酸エステル塩含有粉
末洗剤を安定に製造する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for stably producing a powder detergent containing a high quality α-sulfo fatty acid ester salt.

肪酸エステル塩は、酸、アルカリの存在下、或いは高温
下においてエステル結合が加水分解してα−スルホ脂肪
酸となり、洗浄作用が低下することが問題である。General formula R-C)l -C00AO3M (wherein, R is an alkyl or alkenyl group having 4 to 22 carbon atoms, the group is an alkali metal, alkaline earth metal, alkanolamine or ammonium, and A is an alkyl group having 1 to 4 carbon atoms) Neutralized α-sulfo fatty acid ester salts represented by (group, H, or group) have good biodegradability and hard water resistance, and are relatively inexpensive surfactants, so they are suitable for powder detergents. It is attracting attention as a base material. However, the problem with α-sulfo fatty acid ester salts is that the ester bonds are hydrolyzed to α-sulfo fatty acids in the presence of acids, alkalis, or at high temperatures, resulting in decreased cleaning action.

０９８号公報）で目的を達する試みもなされているが、
この方法は、乾燥粒子の機械的強度が弱くて微粉になり
易く、製品の品質上問題がある。In order to improve the stability of powdered detergents containing α-sulfo fatty acid ester salts during storage, conventionally, specific alkaline agents have been used (Japanese Patent Application Laid-Open No. 52-28507 No. 1),
Or a method of adding a stabilizer (Japanese Patent Publication No. 53-28163)
No. 2) has been proposed. In addition, a manufacturing method of spray drying without contacting with an alkaline agent (Japanese Patent Application Laid-Open No. 58-47
Although an attempt has been made to achieve the objective in the publication No. 098),
In this method, the mechanical strength of the dried particles is weak and they tend to become fine powder, which poses problems in terms of product quality.
また、特開昭５８−４７０９８号公報に記載中の方法は
噴霧される界面活性剤濃度が比較的低いために乾燥に要

とは言えない。Furthermore, the method described in JP-A-58-47098 is disadvantageous in terms of the energy required for drying because the concentration of the sprayed surfactant is relatively low. Furthermore, in the method described in the publication, in order to avoid contact between the α-sulfo fatty acid ester salt component and the alkaline agent, the two components are sprayed independently, but because the spraying positions are close, half of both components are sprayed. This is not a preferred method because there is a risk of hydrolysis due to fusion of dry matter.

動性を改善する目的のものである。On the other hand, as a method for producing granular detergent, a slurry component containing a surfactant is sprayed from the top of a spray drying space, and a slurry component containing an inorganic salt component is sprayed upward from the bottom of the spray drying space. Attempts have been made to modify the surface condition of (JP-A-53-51212, JP-A-53-57208). However, these methods are aimed at improving the hygroscopic solidification properties, pressure solidification properties, and fluidity of granular detergents.

It's about doing.

の問題点が解決されることを見出し本発明を完成した。The present inventors have conducted extensive research to solve the problem that a method for stably and efficiently producing powdered detergent containing α-sulfo fatty acid ester salts of good quality has not yet been found. The component containing a highly concentrated neutralized product of sulfo fatty acid ester salt is sprayed upwards below the hot air blowing section of the spray drying tower, and the other ingredients are sprayed downward above the hot air blowing section of the spray drying tower. The inventors have found that the above problems can be solved by doing the following, and have completed the present invention.

特徴とするα−スルホ脂肪酸エステル塩含有粉末洗剤の
製造方法を提供するものである。That is, in the present invention, a highly concentrated neutralized product of α-sulfo fatty acid ester salt is sprayed upward from a hot air blowing section in a spray drying tower, and a slurry of other components containing a strong alkali is passed through the hot air blowing section. The present invention provides a method for producing an α-sulfo fatty acid ester salt-containing powder detergent, which comprises spraying downward from an upper portion.
本発明によって、高品質でα−スルホ脂肪酸エステル塩
の保持率の良好なα−スルホ脂肪酸エステル塩含有粉末
洗剤が効率的に製造される。According to the present invention, a powder detergent containing an α-sulfo fatty acid ester salt that is of high quality and has a good retention rate of the α-sulfo fatty acid ester salt can be efficiently produced.
本発明の特徴の第１は、α−スルホ脂肪酸エステル塩の
高濃度中和物を用いることにある。The first feature of the present invention is the use of a highly concentrated neutralized product of α-sulfo fatty acid ester salt.
α−スルホ脂肪酸エステル塩の乾燥特性は石鹸等の均質

を極力防ぐことができる。The drying characteristics of α-sulfo fatty acid ester salts are similar to those of homogeneous materials such as soaps, and there is almost no constant rate drying period, and there is a decreasing rate drying period immediately, and moisture movement is due to diffusion, so it is very difficult to dry. It is difficult to dry. Therefore, by spraying a highly concentrated neutralized product with a low water content, drying time can be shortened and hydrolysis due to contact with hot air can be prevented as much as possible.

は全く生じない。In addition, since the above-mentioned highly concentrated neutralized product has a high viscosity, it is sprayed as a uniform particle with an average particle size of about 250 mm at the time of spraying, so there is almost no generation of fine powder, making it an excellent powder detergent. You can get it. Therefore, problems such as the possibility that the powder product is classified and the product cannot be made uniform, and the generation of fine powder during handling of the powder product that adversely affects the human body do not occur.

を達成し得ることを見出した。Generally, the static pressure condition inside the spray drying tower is a slight negative pressure (-2 to
6 mmHg), and in many cases cooling air is introduced from the bottom of the tower to cool the dried product. The present inventors focused on this point, and sprayed a highly concentrated neutralized product of α-sulfo fatty acid ester salt into the air stream flowing in from the bottom of the tower.
The object of the present invention can be achieved by drying a highly concentrated neutralized product of α-sulfo fatty acid ester salt by utilizing the fact that the air flow is heated by the hot air sent from the hot air blower when it heads upward. I discovered that.

で高品質のものが得られるのである。The above-mentioned highly concentrated neutralized product has a significantly lower water content than normal products, so it can be dried with a small amount of heat and in a short time. By spraying a highly concentrated neutralized product of salt, a high quality dry product can be easily obtained. In addition, in the method of the present invention, α-
Since the piping that sprays the highly concentrated neutralized product of the sulfo fatty acid ester salt is located, the highly concentrated neutralized product of the α-sulfo fatty acid ester salt in the pipe is not exposed to the temperature increase due to hot air, and therefore hydrolysis is prevented. There is no risk, and
Since there is no risk that the powder accumulated on the piping will be carbonized or the quality will deteriorate significantly due to high temperatures, a high quality product with a high ester retention rate can be obtained.
