Mini Milk Spray Dryer Machine
The mini spray dryer machine is mainly used in universities, research institutes and laboratories of food, medicine and chemical enterprises to produce micro-particle powders, and has broad-spectrum applicability to all solutions (emulsions, suspensions), and mini spray dryer machine are suitable for heat sensitivity. Because the sprayed material is only exposed to high temperature when it is sprayed into mist-shaped particles, it is only heated instantaneously, which can keep the active materials from being damaged after drying. Let's take the milk spray dryer as an example to introduce the mini spray dryer price .
Mini spray dryers machine are used to convert liquids (i.e. solutions, suspensions or emulsions) into dry powders. This is a fast, gentle one-step drying process. The main application is milk powder production. In general, liquid milk is easily denatured and difficult to store for long periods of time. To extend its shelf life and facilitate transportation, milk is spray-dried into powdered milk.
There are two main methods of milk powder production: dry method and wet method. Compared with the dry process, the wet process is more complicated, and the milk powder needs to be processed through multiple processes such as raw milk testing, filtration, purification, preparation, homogenization, sterilization, concentration, spraying, and packaging. Due to the relatively poor uniformity and quality of the products produced by the dry process, the taste and flavor are not as good as those of the wet process milk powder. At present, many dairy companies use wet process to ensure the taste and quality of milk powder. The dry process is that all raw and auxiliary ingredients are weighed, sterilized, mixed and packaged in a dry state to make milk powder. The wet process milk powder is made by spray-drying raw fresh milk directly and adding nutrients. After passing through the milk spray dryer, it is powdered at one time. There are not too many intermediate links, so as to avoid the milk powder from being polluted and ensure the quality of the milk powder.
The process of mini spray dryer:
1. The installation of the drying chamber. Hold the drying chamber with both hands, then insert it into the fixing clamp of the drying chamber, and lock the locking nut of the drying chamber (as long as the drying chamber can rotate in the clamp).
2. The device of the cyclone separator. Put the lock nut, sealing ring and stainless steel gasket of the cyclone separator on the air outlet pipe of the cyclone separator, insert it into the air outlet pipe of the equipment, and adjust the position of the air outlet of the drying room and the air inlet of the cyclone separator. Align them straight, connect the two ports with a clamp, and finally tighten the cyclone lock nut.
3. Connect the collection bottle to the cyclone with a clamp.
4. Connect the collecting pipe to the drying chamber with a clamp.
5. Attach the spray chamber to the device and connect the 4mm trachea (for general needle) and 6mm trachea (for spray).
6. Attach the silicone tubing to the creep pump and insert it into the spray chamber feed port.
7. Power on the milk spray dryer, turn on the switch button on the spray dryer, enter the spray dryer system interface, turn on relevant switches, such as fan heaters, etc., set relevant parameters, and start the test after completion.
Main features:
1. The laboratory stainless steel spray dryer is operated by a large color touch screen, a combination of automatic control and manual control, ten-stage program temperature control, and its own memory function.
2. One-button boot, set the spray process parameters, when the temperature reaches the predetermined temperature, the peristaltic pump will start automatically, and the running animation will be displayed on the touch screen; after pressing the stop button, the machine will automatically shut down safely.
3. Manual control: During the experiment, you can switch to the manual state to adjust the process parameters, and the whole experiment process displays the dynamic color touch screen.
4. Shutdown protection function: Just press the stop button when shutting down, the spray dryer will stop running immediately, and the heating part of the equipment will not be burned out due to misoperation.
5. The spraying, drying and collection system is made of transparent high-borosilicate heat-resistant glass material, so that the spray drying process can be carried out in a pollution-free and stable environment, and the entire spray drying experiment process can be directly observed, allowing researchers to control the experiment The process and experimental results provide convenience, and can find and solve problems in time.
6. The laboratory stainless steel spray dryer has a built-in oil-free air compressor, the particle size of the powder is normally distributed, the fluidity is very good, and the noise is very low, less than 60db;
7. The atomization structure of the spray dryer is made of stainless steel and has no auxiliary equipment, which is convenient to use.
8. In the design of drying temperature control, we use real-time regulation of PID constant temperature control technology, so that the temperature control in the whole temperature area is accurate, and the heating temperature control accuracy is ±1 °C.
9. In order to keep the samples clean, the spray dryer is also equipped with an air inlet filter.
10. The feeding volume can be adjusted by the feeding peristaltic pump, and the small amount of sample can reach 50ml. Magnetic stirrer optional
The finished dry powder after drying has a relatively uniform particle size, and more than 95% of the dry powder is in the same particle size range.
11. The laboratory stainless steel spray dryer is equipped with a nozzle cleaner for viscous materials. When a blockage occurs, the nozzle cleaner will automatically clear it, and the frequency of the needle can be adjusted automatically;
