Soap Saponification and Vacuum Drying System

The soap saponification equipment/machine mainly includes Saponification tank and vacuum drying system.

The main raw materials for the saponification reaction include oils and fats, alkaline substances (sodium hydroxide or potassium hydroxide) and water, while other additives are tailored to specific needs.

Saponification is the core process of soap production and mainly involves the following raw materials:

1. Greases:

Vegetable oils: such as olive oil, palm oil, coconut oil, etc., rich in triglycerides.

Animal oils: such as butter, mutton fat, etc., can also be used for saponification reactions.

Oils and fats are the main components of the saponification reaction, providing a source of fatty acids.

2. Alkaline substances

Sodium hydroxide (NaOH): Commonly used in the production of hard soaps, it reacts effectively with greases.

Potassium hydroxide (KOH): Typically used in the production of liquid soap, which produces a softer soap.

Alkaline substances act as catalysts in the reaction, promoting the hydrolysis of oils and fats.

3. Water

Water is an indispensable solvent in the saponification reaction, helping to mix greases and alkaline substances evenly and facilitate the reaction.

4. Other additives

Salt (sodium chloride): added later in the reaction, it can promote the precipitation of soap, which is called salting out.

Fragrances and colors: used to improve the appearance and smell of soaps and increase market appeal.

Active Agent: Sometimes added to enhance the cleaning properties of the soap.

In summary, the main raw materials for the saponification reaction include oils and fats, alkaline substances (sodium hydroxide or potassium hydroxide hydrate) and water, while other additives are determined according to specific needs

The soap vacuum dryer is mainly composed of heater, vacuum drying system and twin-screw strip press.
