Scraper surface heat exchanger (SSHE) is a key process equipment, widely used in food processing, chemical, pharmaceutical and other industries, especially in the production of margarine and shortening plays an important role. This paper will discuss in detail the application of Scraper surface heat exchanger (SSHE), especially its importance in the production of margarine and shortening.
The basic principle and function of Scraper surface heat exchanger (SSHE)
The core function of the Scraper surface heat exchanger (SSHE) is to rapidly crystallize liquid materials in a short period of time through rapid cooling. This rapid cooling process can effectively control the crystalline structure of the material, thus affecting its physical and chemical properties. Scraper surface heat exchanger (SSHE) is usually composed of cooling drum, agitator, cooling medium circulation system, etc., by controlling temperature, stirring speed and time to achieve accurate control of material crystallization process.
Application of Scraper surface heat exchanger (SSHE) in food industry
The production of margarine
Margarine is a common food ingredient, widely used in baking, frying and seasoning. The production process includes grease mixing, emulsification, cooling and crystallization. Quenching crystallizer plays a crucial role in this process.
Grease mixing and emulsification: The production of margarine first requires the mixing of various fats and oils and the formation of a stable emulsion through emulsifiers. This process ensures an even distribution of the oil and lays the foundation for subsequent crystallization.
Quenching crystallization: After emulsifying the oil mixture into the quenching crystallizer, through rapid cooling, so that it in a short time of rapid crystallization. This process effectively controls the size and distribution of crystals, which affects the texture and taste of margarine. Quenching crystallizer by controlling the temperature and speed of the cooling drum to ensure the stability and uniformity of the crystallization process.
Post-crystallization treatment: The quenchly-crystallized material goes through subsequent mixing and processing to ensure that it has the appropriate physical properties, such as softness and stability.
Shortening production
Shortening is an oil used to make foods such as pastry, pastries and cookies, and is produced in a similar process to margarine, but with higher requirements for crystalline structure. Scraper surface heat exchanger (SSHE) also plays an important role in the production of shortening.
Selection and mixing of oils: The production of shortening requires the selection of oils with specific melting points and crystallization properties, and the mixing of them into a uniform liquid. This step provides the basis for the subsequent crystallization process.
Quench crystallization: the mixed oil enters the Scraper surface heat exchanger (SSHE), which is rapidly cooled to form crystallization. The Scraper surface heat exchanger (SSHE) makes the oil form a fine and uniform crystal structure by precisely controlling the cooling conditions. This fine crystal structure gives the shortening good plasticity and crisp taste.
Subsequent treatment: The crystallized shortening needs to be further stirred and formed to ensure that it has the proper physical properties, such as hardness and stability. The use of Scraper surface heat exchanger (SSHE) can significantly improve the production efficiency and product quality of shortening.
The application of quenching crystallizer in other industries
Chemical industry
In the chemical industry, Scraper surface heat exchanger (SSHE) is widely used in the production process of various chemical products, such as resins, dyes and pigments. By quenching crystallization, the crystal structure of these chemical products can be controlled to improve their purity and stability. For example, in resin production, the Scraper surface heat exchanger (SSHE) can make the resin quickly cure and form a uniform crystal structure, thereby improving the mechanical properties and heat resistance of the resin.
Pharmaceutical industry
In the pharmaceutical industry, Scraper surface heat exchanger (SSHE)s are used in the crystallization and drying process of drugs. By quenching crystallization, the crystal form of the drug can be controlled, and its solubility and bioavailability can be improved. For example, in the production of antibiotics, the Scraper surface heat exchanger (SSHE) enables the antibiotic to crystallize rapidly, improving its purity and efficacy. In addition, the Scraper surface heat exchanger (SSHE) can also be used to produce slow-release preparations of various drugs, and the release rate of drugs can be adjusted by controlling the crystal structure.
Other application areas
In addition to the food, chemical and pharmaceutical industries, Scraper surface heat exchanger (SSHE)s are also widely used in other fields, such as textiles, electronics and materials science. In the textile industry, Scraper surface heat exchanger (SSHE)s are used in the production and processing of fibers to improve their strength and wear resistance by controlling the crystalline structure of the fibers. In the electronics industry, Scraper surface heat exchanger (SSHE)s are used in the production of semiconductor materials to improve the performance and stability of semiconductor materials by precisely controlling the crystallization process. In the field of materials science, Scraper surface heat exchanger (SSHE)s are used for the development and research of new materials, regulating the physical and chemical properties of materials by controlling the crystalline structure.
Conclusion
Scraper surface heat exchanger (SSHE), as an efficient crystallizing equipment, plays an important role in many industries. Especially in the food industry, it significantly improves product quality and production efficiency in the production of margarine and shortening through rapid cooling and precise control of the crystallization process. With the continuous progress of technology, the application range of Scraper surface heat exchanger (SSHE) will continue to expand, and show its unique advantages and value in more fields.
