Sorbic acid is an efficient and safe preservative and preservative recommended by the International Food and Agriculture Organization (FAO) and the World Health Organization (WHO). It is widely used in food, beverage, tobacco, pesticide, cosmetics and other industries. As an unsaturated acid, sorbic acid can also be used in resin, fragrance and rubber industries. Sorbate and potassium sorbate (hereinafter referred to as sorbate and potassium salts) are a good food preservative,

It is widely used in Western developed countries, but it is not widely used in China. As a kind of food additive recognized as safe, efficient and anti-corrosion, sorbate and potassium salt will be more and more widely used in China's food industry. White or yellowish white crystalline powder; It stinks. This product is easily soluble in ethanol, dissolved in ether, and very slightly dissolved in water.

Potassium sorbate (potassium) can effectively inhibit the activity of mold, yeast and aerobic bacteria, and prevent the growth and reproduction of harmful microorganisms such as botulinum, staphylococcus, Salmonella, etc., but it is almost ineffective for beneficial microorganisms such as anaerobic bacillus and Lactobacillus acidophilus, and its inhibiting effect is stronger than bactericidal effect, so as to effectively extend the preservation time of food. And maintain the flavor of the original food.

SZG series double-cone rotary vacuum dryer is a double-cone rotary tank. In the vacuum state, steam or hot water is heated into the jacket, and the heat is in contact with the wet material through the inner wall of the tank. The vapor evaporates after the wet material absorbs heat and is pumped away through the vacuum pump through the vacuum exhaust pipe. Because the tank is in a vacuum state, and the rotation of the tank makes the material constantly up and down, inside and outside, it speeds up the drying speed of the material, improves the drying efficiency, and achieves the purpose of uniform drying.
