1Small and medium-sized spray dryer for egg productsWorking Principle:

After initial, intermediate, and high-efficiency filtration, the air enters the air heater. The heating methods of the air heater include hot air stove or electric heating+steam heating, etc. When the air is heated to the set temperature, it enters the hot air distributor in a tangential direction. The air, after being treated by the hot air distributor, uniformly and helically enters the drying chamber. At the same time, the material liquid is atomized into 20-60um droplets by the atomizer. When the droplets come into contact with the hot air, they quickly vaporize and dry into powder or granular products. Dry powder or granular products fall onto the four walls of the cone in the drying chamber and slide to the bottom of the cone to enter the powder accumulation cylinder (or directly collect materials using a cyclone separator). A small amount of fine powder enters the cyclone separator with air for separation. After that, the exhaust gas is discharged from the fan outlet or enters the water foam dust collector (Venturi) before being discharged, and the material will not be lost.

The machine adopts parallel flow spray drying, and the droplets flow in the same direction as the hot air. Although the temperature of hot air is high, because the hot air enters the drying chamber and immediately contacts with spray droplets, the temperature in the drying chamber drops sharply from top to bottom, and the materials will not be overheated, which is particularly suitable for drying heat sensitive materials. The temperature of the discharged product is generally around 150 ℃.

The inner cylinder, pipelines, and all contact material components of this unit are made of SUS304 stainless steel material (materials can also be made according to customer requirements).

This series of spray dryers can usually be used for drying liquid materials with a moisture content of 50% -80%. Even if the moisture content of special materials is up to 90%, they can be dried into powder and granular products without concentration.

2、 Characteristics of the dryer:

1. The drying speed is fast. After being atomized by an atomizer, the surface area of the liquid is greatly increased, and 95-98% of the water can be evaporated instantly in a high-temperature airflow, completing the drying process in just a few seconds.

2. Parallel flow spray drying can make the droplets flow in the same direction as the hot air. Although the temperature of the hot air is high, because the hot air enters the drying room and immediately contacts with the spray droplets, the indoor temperature drops sharply, and the materials will not be excessively heated. It is also suitable for

Drying of thermosensitive materials.

3. Due to the instantaneous drying process, the particles of the finished product can basically remain spherical, and the product has good dispersibility, flowability, and solubility.

4. The production process is simplified and the operation control is convenient. Spray drying is usually used for drying solutions with a moisture content of 50-80%. Even if the moisture content of special materials is up to 90%, they can be dried into powder products at one time. After most products are dried, there is no need for further crushing and screening, which reduces the production process, simplifies the production process, and improves the purity of the products. According to production

The required particle size, bulk density, and moisture content of the product can be adjusted and controlled by changing the operating conditions within a certain range.

5. In order to prevent material contamination and extend equipment service life, all parts in contact with the material are made of SUS304 stainless steel material. For the convenience of operation, the operating system adopts integrated control, that is, installing indicator devices and opening and closing devices for each component in the control cabinet.
