Centrifugal concrete of Chinese traditional medicine spray drying unit

Centrifugal concrete of Chinese traditional medicine spray drying unit

1. The main design requirements of the centrifugal spray drying system:

　　(1) Dry material name: Chinese medicine extract (solid concentration: about 30-35%)

　　(2) Heating method: steam heating + electric heating compensation

　　(3) Discharge and dust removal method: Modular two-stage cyclone separator + water film dust collector

　　(4) Atomization form: mechanical high-speed centrifugal atomizer (frequency conversion speed regulation)

　　(5) Feeding method of material liquid: DC stepless speed-regulating screw pump (linked control with outlet temperature meter)

　　(6) Compressed air pressure: 0.6apm

　　(7) Voltage: 220/380V

　　 Two. Description of the main components of the centrifugal spray drying system:

　　(1) Main drying tower:

　　The main tower structure is designed and manufactured with a support structure, which is convenient for on-site installation; the main tower is equipped with 2 cleaning and observation doors on the front and rear, which is convenient for cleaning; the main tower is equipped with an air hammer on the straight section and the cone section to assist in cutting, effective heat preservation The layer thickness is 80mm, and the heat preservation performance is high; the top of the main tower is equipped with 4 hoisting rings, 2 observation mirror lamp devices, and the outer surface of the top is a non-slip checkered plate.

　　(2) Hot air volute and distributor:

　　The hot air volute is made of high-quality SUS304 material, and the hot air distributor is an adjustable structure, which is convenient for disassembly, assembly and cleaning.

　　(3) Mechanical atomizer:

　　 uses the domestic high-quality manufacturer's products (Hangzhou Xinhai), the structure is mechanical, water cooling, imported NSK bearings, and the seals are high temperature seals.

　　(4) Heating box system:

　　Modular heating box design structure; adopts steam heating + electric heating compensation method, steam heater adopts U-shaped new heating coil structure stainless steel seamless tube outside stainless steel fin type; electric heating tube adopts stainless steel fin electricity The heating pipe and box body are insulated with high-quality aluminum silicate fiber cotton.

　　(5) Modular cyclone separator and pipeline:

　　The cyclone separator layout adopts modular structure design and manufacture, and the discharge butterfly valve adopts sanitary quick-opening structure, which is easy to clean without dead corners;

　　(6) Medium circulation system:

The 　　 system design adopts an open-circulation method, and is equipped with a supply air induced draft fan, which is regulated by a ventilation valve, and the induced draft fan adopts frequency conversion regulation. An electric non-return one-way air valve is set on the air pipeline between the secondary cyclone separator and the induced draft fan, which is controlled in linkage with the induced draft fan.

　　(7) Air filter:

　　The system is equipped with primary, medium and high-efficiency three-effect air filters, with a cleanliness of 100,000 grades, a structure that can be easily disassembled, and a high-efficiency pressure difference display.

　　(8) Program control system:

　　 uses an independent control cabinet.

　　(9) Exhaust gas treatment system:

　　 uses a water film dust collector, all stainless steel production, exhaust gas emission standards.

　　(10) bracket, platform, escalator, guardrail:

　　The layout is designed according to the customer's site conditions, and it is made of all stainless steel materials. In order to make the site layout reasonable, the site production and installation process is adopted.
