Freeze drying foundation make-up lyophilizerThe working principle is based on freezing and sublimation technology. Specifically, it first freezes materials containing water (such as medicinal liquids, plant extracts, etc.) into a solid state at low temperatures, and then directly sublimates the solid ice into gas in a vacuum environment, thereby removing most of the water in the material and obtaining freeze-dried powder with very little water content. This process can largely preserve the active ingredients in the material, prevent them from becoming inactive due to high temperature or oxidation, and extend the shelf life of the product.
Freeze drying foundation make-up lyophilizerWith its core advantages of low-temperature dehydration, retention of active ingredients, and extended shelf life, freeze-drying technology equipment has been widely used in multiple fields, as follows:
1、 Cosmetics field
Skincare products: Freeze drying technology can significantly improve the stability and shelf life of skincare products. For example, the freeze-dried facial mask can maintain the original activity and nutrients, quickly dissolve and release the effective ingredients when used, and improve the skin care effect. In addition, freeze-drying technology is also used to produce vitamin C freeze-dried powder, collagen freeze-dried powder, etc. These products have the characteristics of quick solubility, high activity, and easy preservation.
Color cosmetics: Freeze drying technology can make lipstick, eye shadow and other color cosmetics more durable and bright, and can also make pearl powder, sequins and other special effect products, bringing more diversified choices to the color cosmetics market.
Medical beauty: Plant stem cell extracts, hyaluronic acid freeze-dried powder and other medical beauty products produced using freeze-drying technology can be used for skin repair, anti-aging treatment and care, and are favored by the market due to their high activity and good stability.
Raw material research and development: In the stage of cosmetic raw material research and development, freeze-drying technology can solidify raw materials with antioxidant, moisturizing, repairing and other effects, and apply them to the development of new products. For example, medical beauty products such as plant stem cell extracts and hyaluronic acid can maintain their biological activity and stability after freeze-drying technology treatment.
2、 Medical field
Drug preparation: Freeze drying machines are used to prepare various drugs, such as antibiotics, vaccines, biological products, etc. Through freeze-drying treatment, these drugs can better preserve their efficacy and stability. For example, thermosensitive drugs such as insulin, immunoglobulin, and tumor targeted drugs are dehydrated through freeze-drying to avoid high temperature inactivation and extend shelf life.
Medical supplies: Freeze drying technology can also be used to prepare medical supplies such as dressings, surgical instruments, etc. The freeze-drying preparation of medical dressings such as bone repair materials and collagen sponges can maintain their biological activity and stability.
Biological sample preservation: Freeze drying technology can be used to preserve various organs such as blood, arteries, bones, skin, cornea, and nerve tissue for a long time. Cells are not destroyed during freeze-drying, and the organism can be revived after rehydration. For example, freeze-dried bones can be stored at room temperature or in a refrigerator for up to 2 years.
3、 Food industry
Cooking ingredients: Meat, eggs, fish, vegetables and other cooking ingredients can be processed through freeze-drying technology to preserve flavor and nutrition, and have strong rehydration properties.
Food industry raw materials: milk powder, egg powder, plant protein powder, tea, dried fruits, meat powder, soybean powder and other food industry raw materials, as well as beverages such as coffee and fruit powder, can all be processed through freeze-drying technology to extend their shelf life.
Supplements: Supplements such as pollen, bee larvae powder, turtle powder, as well as advanced nutritional products such as royal jelly, honey, and herbal preparations, can retain their original nutritional components and active substances after freeze-drying technology processing.
Special foods: high-energy foods such as aerospace food and rations that require long-term storage are also often processed using freeze-drying technology.
4、 Biological products and scientific research field
Biological product preservation: Freeze drying technology is used to preserve biological samples (such as DNA, RNA, cell lines) to avoid degradation. Meanwhile, freeze-drying technology is often used for the drying and preservation of chemical reagents and enzyme preparations.
Research application: In drug formulation development and stability testing, freeze-drying process validation is an important link. In addition, the freeze-drying preservation of plant seeds and microbial strains is also an important application of freeze-drying technology for scientific research or agricultural planting.
Animal and plant research: Freeze dryers are also widely used in the field of animal and plant research. For example, freezing the water in plant tissues into ice crystals through low-temperature freezing, and then sublimating the ice crystals under vacuum can avoid the destruction of thermosensitive components such as polyphenols, flavonoids, terpenes, etc. At the same time, freeze-drying technology can also be used to preserve animal organs, muscles, skin and other tissues, maintain structural integrity, and facilitate subsequent histological and pathological analysis.
