Fully Automatic Pharmaceutical Dryers Pressure Spray Stainless Steel 350Kg/H

Pharmaceutical Dryers Centrifugal Industrial Powder Spray Drying Machine

Product description of Spray Dryer

After the normal temperature air of the pressure spray dryer is sent to the heater by the blower for heating, the hot process air enters the cyclone dust collector for dust removal (indirect gas-fired hot air furnace can be used to consider the purity), and enters the hot air distributor through the hot air duct. drying tower.

The 70% solid content liquid is pressed to the pressure nozzle by the homogenizer pump at a flow rate of ~1350kg/h, and atomized into fine droplets that contact with the hot air and evaporate quickly. Enter the cyclone dust collector for separation and collection, and the waste wet air is evacuated.

The products received at the bottom of the tower and the cyclone are collected and packaged by the unloader in the way of cold and dry air flow.

Main Parameter of Spray Dryer

Main Features of Spray Dryer

    1. The quality of the product can be controlled stably.

The liquid pump in this unit is controlled by frequency conversion speed regulation, which can easily change the atomization effect, so as to control the particle size of the product;

The hot air distributor with three-layer air distribution screen is designed to make the hot air run parallel and downward, and control the residence time of the material, which is suitable for both high temperature instant drying and low temperature long-term water evaporation;

The advanced fuzzy control technology is used to establish the automatic control of the outlet air temperature and the feeding amount, so that the feeding amount can automatically track the outlet air temperature for automatic adjustment, so as to ensure the stability of product quality.

    2. Can reduce sticky wall coking phenomenon.

According to the material characteristics, in the design of the tower diameter and tower height, the standard tower diameter is increased by about 10%, and the tower shape is also adjusted accordingly.

It not only ensures that the powder does not reach the tower wall before drying, but also ensures that the powder has sufficient residence time in the hot air to complete low-temperature drying, and at the same time ensures that the powder is not easy to stick to the wall after contacting the tower wall.

3. In-tower finishing

All the contact points in the host with the material adopt plane or arc transition, and the welding seam is processed by grinding, polishing and fine polishing process to avoid trachoma, dead angle and other phenomena.

4. High dust recovery rate.

The dust removal system of the spray drying unit is formed in two stages. The first-stage cyclone adopts a high-efficiency separator, which is an optimized combination, and its powder receiving rate can reach more than 98%.

5. The whole unit is made of stainless steel in contact with the material, and the transmission parts are well sealed, which can be waterproof and oil-proof; the cyclone outlet is operated with a sealed butterfly valve to prevent air leakage.

Application advantages

1. The drying speed is fast, and the surface of the material liquid is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated instantly, and it only takes ten to ten seconds to complete the drying step. Suitable for drying heat-sensitive materials;
 

2. The products obtained by drying are spherical particles with uniform particles, good fluidity, good solubility, high product purity and good quality;
 

3. Wide range of applications, users can choose to use hot air drying and cold air granulation according to the characteristics of the material, which has strong adaptability to the material.
 

4. The operation is simple and stable, the control is convenient, and it is easy to realize automatic operation.
