Fruit and vegetable powder centrifugal spray drying tower

According to its own technical scheme, the bidder is equipped with measures to reduce the sticky wall phenomenon, such as setting up the drying room purge device, the drying room jacket cooling device, etc.;

The bidder shall be equipped with a cooling atomizer according to its own technical scheme, such as setting up a primary cold air device;

The tower body adopts 304 stainless steel not less than 3mm, and the polishing roughness of the inner wall is not more than 0.6 μ m;

Allintness deviation of tower installation: 1.5L / 1000 (L is the length of cylinder);

If the jacket is cooled by cold air, the exhaust air of the cooling air should be recovered to the fresh air outlet to achieve the purpose of energy saving;

The tower shall be equipped with observation holes and corresponding lighting devices to observe the operation state and drying process of the atomizer and purge device, and the upper person operation platform

The atomizer lifting device is set on the top of the tower, and the safety fence is set around the top of the tower.

The project intends to use spray drying technology to make the solution, emulsion, suspension, paste and other fruit and vegetable materials become dry powder, fine and medium particles after spray drying. Realize fast speed, high efficiency, less process, save manpower. Especially for the heat-sensitive fruit and vegetable materials can maintain the color, aroma and taste of the material. Drying products are of good quality, good fluidity, solubility, high purity, environmental health, to solve the conventional production of fruit and vegetable powder grain coarse, poor flavor and other deficiencies.

Selection and configuration requirements of fruit and vegetable powder centrifugal spray drying tower：

Water evaporation: 1000 Kg

Air volume for drying: 30,000 kg / h

Heat used for drying: 120,104kcal / h

Tower type: φ 75007300 (diameter straight section height) cone Angle of 50 degrees Total equipment height: 16m。

Aerozation: high speed centrifugal atomization, RW1000 type Energy consumption: electricity 70 Kw steam: 2200 Kg / h。

Note: In the light of the drying process, the following measures are set in the system:

A: The cone part of the drying tower is changed from the original insulation layer as an air cooling separator, so as to reduce the temperature of the inner wall of the drying tower accordingly, so as to prevent the sticky wall of the sugar-containing materials.

B: Air hammer vibration device is reasonably set in the straight cylinder and cone of the drying tower to reduce the attached wall of flying powder and the cleaning of slightly adhesive materials.

C: The centrifugal atomizer on the top of the tower is equipped with an air cooling system to ensure that the material does not turn over the top, does not focus in the high temperature area at the top of the tower, and cool and protect the atomizer.

D: The dehumidification air cooling treatment system is attached to ensure that the Microsoft materials are not held in the aggregate bin, and the surface water is removed to eliminate the phenomenon of damp material agglomeration after packaging.
