Problems solved by technology

[0005] The above-mentioned one-time molding production method has high requirements on equipment, complicated process conditions, and belongs to the intermittent production mode, which cannot realize continuous large-scale production
In industrial production, laundry soap powder is prepared by adding powdery to granular dry sodium soap to the rear distribution system (rotary mixer). During the use of the product, some dry sodium soap powder floats on the water surface and dissolves too long Long phenomenon, to a certain extent, affects the overall performance of laundry soap powder and the user experience of consumers, and the addition of powdered soap powder raw materials after passing through will cause a large amount of dust on the production site, which does not meet the requirements of clean production

Embodiment 3

[0064] (The production process of laundry soap powder of the present invention, the following percentages are all percentages by weight)

[0065] Please refer to the attached figure 1 Shown, and after carrying out the preparation of soap powder slurry according to embodiment 1 or embodiment 2, enter high tower powder spraying system, finish the atomized soap particle. The base powder coming out of the powder spraying tower is further aged, cooled and sieved by wind, conveyed by the conveyor belt and measured by the weight loss scale, and then sent to the post-equipment rotary mixer. The weight ratio of the base powder in the mixer is 84%. At the same time, it is mixed with several solid raw materials from the after-mixing system: functional small materials (enzyme preparations, functional additives) 0.9%, color particles 1.0%, zeolite 3%, soda ash 8%, The liquid material essence 0.1% and non-ionic surfactant 3% are continuously and uniformly mixed into laundry soap powder s...

Abstract

The invention discloses laundry soap powder slurry, a preparation method thereof and an industrial production technology of laundry soap powder. The industrial production technology mainly comprises the steps of: 1) directly adopting fatty acid and liquid alkali to conduct neutralization reaction in a batching kettle of a front preparation system to participate in slurry preparation, 2) allowing the slurry after technical optimization treatment to be capable of smoothly entering a high-tower powder spraying system through a high pressure pump to produce base powder, and 3) adding the base powder and other post preparation raw materials, continuously and evenly mixing with a screw mixer, preparing a semifinished product of the laundry soap powder, conveying to a powder bin with a conveyor belt, and packaging into a finish product. According to the technology, high-tower powder spraying equipment is adopted for production, and no other additional special device is added. Compared with the laundry soap powder produced by the original technology (adding powdered to granular sodium aliphatate during post preparation), the produced laundry soap powder has the characteristics of uniform dispersion and adhesion of sodium aliphatate, short product solution time, low agglomeration resistance and good liquidity, and automatic packaging and continuous mass production of the soap powder can be realized.

Description

technical field [0001] The invention relates to a production process of laundry soap powder, which belongs to the field of industrialized production of laundry powder, and in particular relates to a slurry in the process of producing laundry soap powder and a preparation process thereof, and an industrial production process method of laundry soap powder containing the slurry. Background technique [0002] In order to comply with the green development trend of daily chemical products, the production of washing powder products is developing in the direction of energy saving and environmental protection, reducing the use of ineffective chemicals, and using renewable resources as raw materials. [0003] The main component of laundry soap powder products is dry sodium soap (usually sodium fatty acid) derived from animal and vegetable oils (or mixed animal and vegetable oils), which is a renewable resource. Partially replace petroleum-based surfactants in washing powder products w...
