Detailed description

Project Description:
Also known as jelly. Colloidal particles or polymers in a sol or solution are interconnected under certain conditions to form a spatial network structure, and the structure voids are filled with a liquid as a dispersion medium (which may also be a gas in a dry gel), such a special The dispersion system is called a gel. No liquidity. The interior often contains a large amount of liquid. For example, the water content of blood gel and agar can reach more than 99%. Can be divided into elastic gel and brittle gel. After the elastic gel loses the dispersion medium, the volume is significantly reduced, and when the dispersion medium is reabsorbed, the volume re-expands, such as gelatin. When the brittle gel loses or reabsorbs the dispersion medium, the shape and volume do not change, such as silica gel. The process of forming a gel from a solution or sol is called gelation.

I. Project Overview: The
special spray dryer for condensing traditional Chinese medicine extract is a drying machine developed for the absorption of foreign technology and suitable for traditional Chinese medicine products with low melting point and high sugar content. It has the characteristics of non-stick wall and low moisture absorption. The device determines the process conditions of spray drying according to the dry product and properties; the degree of automation is high; the operation is convenient; the symbol 'GMP' requirement; the calculation and safety department of the process parameters are completed by a computer. The successful development of the device; solved many technical problems that have low melting point for many years; the high-sugar-containing Chinese medicine products can not be spray-dried; it is also a new development of spray drying in the application technology of spray drying in the traditional Chinese medicine pharmaceutical industry. Sex, Jianda's dry ZLPG series spray dryer can complete the whole dry powder collection process.

Second, the equipment overview:
After the air is heated by the heater; the hot air distributor enters the top of the drying tower through the blower; after passing through the hot air distributor, the hot air uniformly enters the drying tower and moves in a spiral shape. The solid pump simultaneously delivers the feed liquid to the centrifugal atomizer at the top of the drying tower, and the liquid is sprayed into extremely small droplets. The surface area in contact with the feed liquid and the hot air is greatly increased, the water is quickly evaporated, and dried in a very short time as a dry product. The dry product is separated from the humid air by a cyclone separator, and the collecting vortex chamber at the bottom of the cyclone separation is sent from the dry air to the small cyclone separator, and is collected in the receiving cylinder, and the exhaust gas is discharged through the induced draft fan.
The hot air system, the purging system and the air delivery system of the dryer are equipped with primary, intermediate and sub-efficient filters, and all the wind entering the drying system is filtered. All parts in contact with the material are made of stainless steel to meet the "GMP" requirements.

Third, the equipment features:
1. Drying speed is fast, generally only takes a dozen seconds, with the characteristics of drowsiness and dryness.
2. The temperature of the droplets during the drying process is relatively low, which is especially suitable for the drying of heat sensitive materials, and can maintain the color, fragrance and taste of the materials.
3. In order to prevent the wall from sticking to the drying tower, the device has a special structure to effectively prevent the sticking of the product.
4. The unique finished air delivery system separates the dried product from the hot humid air in the system in time, avoiding the possibility of moisture absorption or agglomeration of the dried product.
