1. Basic principle:

When the droplets are atomized, they are generally 10-200 microns. At this time, the specific surface area of the material is very large. Therefore, further atomization is required to obtain the appropriate droplet size. In this way, the material drying work is carried out to obtain the desired dried product.

2. Are there any small and medium-sized spray dryers among the small spray dryers? So why use a small spray dryer in an enterprise?

Among the small spray dryers, there are small and medium spray dryers! The specific reason for using a small spray dryer in an enterprise is that this type of dryer can carry out repeated tests to confirm the suitable inlet air temperature, nozzle aperture and other parameters that affect the drying effect of the material! Mainly as an experiment.

3. What is the spray drying of small spray dryer mainly related to?

On a small spray dryer, its spray drying is mainly related to product moisture, particle size, sticky wall and other aspects. Therefore, different products have different atomization methods, rather than generalization.

Spray drying technology is a promising drying technology, which can quickly and easily dry materials into uniform powder materials. At present, most universities and research institutes use experimental spray dryers.Spray dryers for sale.

The factors affecting the growth rate of bovine colostrum granules, such as experimental spray drying, concentration of feed liquid and type of feed liquid, were reviewed, and the growth law and process parameters of bovine colostrum granules were obtained, which provided the basis for the development of fluidized low-temperature granulation device. Colostrum powder was used as raw material, and colostrum granules were prepared by low-temperature fluidized spray granulation technology. The results show that low temperature granulation can keep the product quality unchanged and maintain the original color, aroma, taste and nutrition of the material.

An integrated drying and granulating device integrating low-temperature drying and granulation was developed, and the calculation method of the main process parameters of the dryer was given. The product.

After testing, the loss rate of immunoglobulins in bovine colostrum after drying is smaller than that of freeze-dried products, and the particle size of the products is uniform and smooth, and no crushing and screening processes are required. The development of this device provides a new method for drying heat-sensitive materials. The membrane separation technology is used to improve the processing technology of bovine colostrum, and the microfiltration membrane is used for jun removal and nanofiltration membrane for concentration, which overcomes the traditional process of sterilization. The fat is oxidized, resulting in the defect of odor, and the microbial indicators of the product meet international standards; the concentration process removes 50% of the water, which greatly reduces the energy consumption in the freeze-drying process, which is in line with the concept of building a conservation-oriented society. Due to the use of membrane technology for "cold sterilization" and low temperature concentration, the decomposition of heat-sensitive components is reduced, and the quality of products is improved.Spray drying machine price.

The raw material for processing bovine colostrum powder should be the mixed colostrum within 72 hours after the cow gives birth. Colostrum skimming can be done with a low-temperature refrigerated centrifuge, which has a high degreasing rate and operates at a low temperature (0-10°C), which can effectively prevent the increase in the total number of fine junctions and acidity. Both cobalt source irradiation (60 Co, dose 6~8kGy) and low temperature pasteurization (63℃, 30min) process can achieve good sterilization effect, and the former is more suitable for small-scale production.

The production of colostrum powder can use freeze-drying method or low-temperature spray-drying method. The latter can realize continuous production with high efficiency and low cost, but it has strict requirements on process and equipment performance and requires a large one-time investment.

Spray drying equipment is the fastest growing and widely used form of drying in the field of drying. It is suitable for liquid raw materials such as solutions, emulsions and pumpable suspensions to produce powder, granule or block solid products. Different drying characteristics such as heat sensitivity, viscosity and fluidity of the material to be dried, and different quality requirements such as particle size, particle size distribution, residual moisture content, bulk density, particle shape, etc. of the product, determine the use of different atomizers, airflows Movement and drying chamber structure. There are many types of spray dryers. Common types include centrifugal spray dryers, pressure spray dryers, airflow spray dryers, and traditional Chinese medicine extract spray dryers. The following is an inventory of the characteristics of the four major spray dryers.

Centrifugal Spray Dryer

Centrifugal spray dryer is currently a drying equipment suitable for drying traditional Chinese medicine extract under the condition of better solution to sticking to the wall. Some equipment companies have transformed the centrifugal spray dryer, including changes in process operations and reforms in the structure of the main engine.

The centrifugal spray dryer has a fast drying speed, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated in an instant, and the drying time is only a few seconds. It is especially suitable for heat-sensitive materials. of drying. In addition, the equipment products dried by centrifugal spray dryer have good uniformity, fluidity and solubility, high product purity and good quality.

Not only that, the centrifugal spray dryer also simplifies the pharmaceutical production process and facilitates operation and control. For liquids with a moisture content of 40-60% (up to 90% for special materials), it can be dried into powder products at one time, and it is very convenient to control and manage.

Pressure spray dryer

The pressure spray dryer is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow rate and nozzle size of the liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio.

The pressure spray dryer has a fast drying speed, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95-98% of the water can be evaporated in an instant, and the drying time is only ten to ten seconds. Suitable for drying heat-sensitive materials. The products obtained by the pressure spray dryer are spherical particles with uniform particle size, good fluidity, good solubility, high product purity and good quality.

In addition, the pressure spray dryer is also widely used. According to the characteristics of the material, it can be dried with hot air or granulated with cold air, which has strong adaptability to the material. Simple and stable operation, convenient control, easy to realize automatic operation is also a major feature of this equipment. As shown below:

Airflow spray dryer

Air spray dryer, also known as instant dryer, is especially suitable for solutions, emulsions, pastes, suspensions and even viscous materials. The reason why it is called an instant dryer is mainly because it can spray compressed air or water vapor from the nozzle at a speed of ≥300m/s, and rely on the friction force generated by the speed difference between the gas and liquid to make the liquid material. Separate into fine mist droplets.

Traditional Chinese Medicine Extract Spray Dryer Centrifugal Spray Dryer

The traditional Chinese medicine extract spray dryer is a spray drying equipment specially used to solve the drying problem of traditional Chinese medicine extract and plant extract. The traditional Chinese medicine extract powder dried by this machine will not appear coking and deterioration phenomenon, which greatly increases the yield (more than 95%) and avoids the pollution of mixed medicine.

In order to prevent the material from sticking to the wall, the traditional Chinese medicine extract spray dryer is equipped with an air sweeping wall and a tower wall jacket cooling structure, which can effectively prevent the product from sticking to the wall and coking, and improve product quality and yield. The unique finished product air delivery system can separate the dry finished product from the hot and humid air in the system in time to avoid the possibility of moisture absorption and moisture regain of the finished product.
