Potassium Sorbate Spray Dryer LPG Fuel Advanced PLC HMI Control System

Product Specification

Potassium sorbate introduction: Potassium sorbate is the potassium salt of sorbic acid, colorless or white flaky crystals or crystalline powder. Odorless or slightly odorous, easy to absorb moisture and discolor due to oxidation and decomposition when exposed to air for a long time. Slightly soluble in water. Potassium sorbate and sorbic acid are commonly used organic preservatives, widely used in food, cosmetics, and feed preservation. It is easily absorbed and metabolized by the human body, leaving no residue in the body and non-toxic.

Application in beverages: Potassium sorbate can be added to a variety of beverages such as fruit and vegetable juice drinks, carbonated drinks, and protein drinks. The addition of potassium sorbate greatly extends the shelf life of the product.

Application in candied fruit and candy products: Peanut candy, almond candy, and general sandwich candy can be directly added with an appropriate amount of potassium sorbate for preservation. In order to ensure the preservation and freshness of some high-sugar candy products, the amount of potassium sorbate added should be appropriately increased.

Can potassium sorbate be dried using a spray dryer?

‌Potassium sorbate can be dried using a spray dryer. ‌Spray dryers are important in the preparation of potassium sorbate powder, and their workflow includes steps such as raw material preparation, solution preparation, spray drying, and product collection. Through spray drying, potassium sorbate can form fine powder particles, which have the advantages of high efficiency, fast speed, good product quality, high purity, and flexible operation.

Application scope of spray dryers:
Spray dryers are widely used in many fields, including:

‌Food industry‌: used for the production of milk powder, protein powder, seasonings, preservatives, etc. ‌Pharmaceutical industry‌: used for the preparation of Chinese and Western medicine powders, antibiotics, vitamins and other drugs. ‌Chemical industry‌: used to dry various chemical raw materials and products, such as pigments, dyes, pesticides, etc. ‌Ceramic industry‌: used to dry ceramic slurry to ensure the uniformity and quality of ceramic powder. ‌Environmental protection field‌: used to treat wastewater and sludge and reduce the emission of pollutants.
‌Other fields‌: such as feed, detergents, surfactants, etc. ‌

Properties and uses of potassium sorbate: ​Potassium sorbate is a white to light yellow flaky crystal or powder, odorless or slightly odorous, commonly used as a food preservative, can inhibit the activity of molds, yeasts and aerobic bacteria, and is widely used in food, beverages, cosmetics and other industries‌.

Overview:
Spray dryer is a type of continuous atmospheric pressure dryer [2]. It uses special equipment to spray liquid into mist, which is then dried by contact with hot air. It is used to dry some heat-sensitive liquids, suspensions and viscous liquids, such as milk, eggs, tannins and drugs. It is also used to dry fuels, intermediates, soap powder and inorganic salts.

Working principle:
Air is filtered and heated and enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape. The liquid passes through the high-speed centrifugal atomizer at the top of the tower body and is (rotating) sprayed into extremely fine mist droplets. It can be dried into finished products in a very short time by contacting with hot air in parallel. The finished products are continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the induced draft fan.

Performance characteristics:
◎ Fast drying speed. The surface area of ​​the liquid is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated instantly. The drying time is only a few seconds. It is particularly suitable for drying heat-sensitive materials.
◎The product has good uniformity, fluidity and solubility, high purity and good quality.
◎The production process is simplified and the operation and control are convenient. Liquids with a moisture content of 40-60% (up to 90% for special materials) can be dried into powder products at one time, which is very convenient to control and manage.

Technical specification:

Note: The amount of water evaporation is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is 90oC, the water evaporation curve is shown in the figure above (for model selection reference). As the product is constantly updated, the relevant parameters will change without prior notice.
