Technology of centrifugal spray drying unit

The milk is from the liquid drying characteristics for easy moisture absorption, heat sensitive, food grade requirements higher, and because it is food, more attention should be paid to the product color, fragrance and taste requirements of high characteristic. So we need to be in a short time in dry time, and the end of the water is to be low, the rapid cooling and desiccant after the powder. After we studied the characteristics of the special milk drying, we developed a special spray drying equipment, which has the following characteristics:

A,Product quality can be stable control

The unit atomizer using frenqucy control, can arbitrarily change the atomization effect, which can achieve the proper control of the product particle size; design the air distributor, can adjust hot wind direction; induced draft fan air volume adjustment, in order to regulate the negative pressure in the tower, control material retention time. Is not only applicable to high-temperature instant dry, also suitable for low temperature long time water evaporation; using advanced fuzzy control technology, build a fuzzy mathematical model of the air temperature and the feeding rate and incorporated into the program, let into the feed automatic tracking air temperature is automatically adjusted to ensure the stability of product quality.

B,Can prevent the powder sticky wall coking and suction

According to the characteristics of this kind of material, has made the corresponding adjustment in the design of the tower diameter, which before powder drying is not up to the tower wall, and can ensure the residence time of powder hot air and drying in the tower cone; increase air cooling jacket cooling device, using natural wind cooling tower is the main cone, keep the inner cone temperature at about 50 degrees, when the powder drying temperature rise after the fall within the cone, not because of the local high temperature and zoom in and paste; cone with a total of 3 sets of pneumatic hammer intermittent shock cone, the cone powder quickly slipped into the main tower outlet; dehumidification air feeding the dehumidifier device is out of the wind forcing the host and a cyclone discharge cooling powder and to clean a little pollination material, has two functions, one is rapidly cooled to prevent moisture absorption, the operational requirements in accordance with FDA.

C,Non product material, blocking phenomenon

Host all contacted with raw material by plane or the circular arc transition, contact surface are grinding, polishing processing (fine polishing to] more than 10), avoid sand holes and corners, to prevent buildup of plugging material, in line with the GMP requirements

D,High dust recovery

The dust removal system of spray drying unit is composed of two stage cyclone and water film dust collector. A cyclone with high gas separator, secondary cyclone by diffusion type cyclone separator, the yield reached 97-98%, three levels of the exhaust water film dust absorption efficiency above 99.5%, after absorption liquid recycling, discharge reach the exhaust standard of environmental protection.

E,No pollution, no leakage, easy disassembly, easy to clean

Air pre processing system adopts high efficiency air filter; the unit in contact with the material at the material made of stainless steel to ensure no contamination of the materials; in contact with the material of the transmission parts with good labyrinth sealing, waterproof and oil proof; outlet sealing butterfly valve operation, to prevent air leakage; host, cyclones and other pieces left on the cleaning mouth, induced draft fan discharge pipe adopt movable connection, can be disassembled at any time cleaning disinfection and sterilization processing and so on, reaching the requirement of GMP.

F,To realize automation control

The unit with PLC control system circuit; touch screen animation process, has operability; variable operation parameters to realize the fuzzy technology automatic tracking control; inverter safe and stable adjusting the atomizer; air temperature accuracy can be reached plus or minus 2℃, maximize reduce energy consumption; inlet and outlet, column temperature, column pressure digital display, accurate set and so on.

Many of the advantages of the special spray drying unit configuration, according to many similar products using the experience summary, and refers to the overseas many advanced technology and research and development, now has domestic food additive factory, pharmaceutical factory and chemical factory in the successful use, and conventional units are compared to get the better effect is very obvious. For example: Jiangxi taste is food, Guangdong Minghua flavor, Shanghai Shen Bao spices, Hong Kong Ying biological, good special effects, received industry customers praise and criticism. We will also continue to focus on the spray drying technology to further, more in-depth research and development, for the majority of domestic and foreign enterprises to make better technical support
