Centrifugal spray dryer for coffee extract
Working principle
The coffee extract centrifugal spray dryer is a device where air passes through a filter and a heater, and then enters the air distributor at the top of the centrifugal spray dryer. The hot air spirally and evenly enters the dryer. The material liquid is pumped from the material liquid tank through the filter to the centrifugal atomizer at the top of the dryer, where it is sprayed into extremely small mist droplets. The material liquid and hot air flow in parallel and come into contact, and the water evaporates rapidly. The material is dried into finished products in a very short time. The finished products are discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan. Users can select the heating method and the dust collection and removal methods according to the actual situation.
Product function
It features a large color touch screen operation, combining fully automatic control with manual control. It has both Chinese and English panels, and parameters are displayed on the LCD screen
2. Real-time PID constant temperature control technology ensures accurate temperature control, with a heating temperature control accuracy of ±1℃
3. The spray, drying and collection devices are made of transparent high-quality high-temperature resistant borosilicate glass. The entire spray drying experiment process is visible, which is convenient for controlling the experiment process and promptly identifying and adjusting problems
4. The atomization structure of the two-fluid spray is made of high-precision 316 stainless steel. The particle size of the sprayed powder follows a normal distribution and has good fluidity
5. The jet injector is automatically unclogged (with a needle) and the frequency is adjustable. When the nozzle is clogged, it will be automatically cleared to ensure the continuity of the experiment
6. The feed volume can be adjusted by the feed peristaltic pump, with a minimum sample experimental volume of 30ml
7. It has a protection function. If the fan does not start, the heater cannot start
8. It is equipped with an imported oil-free air compressor with a noise level of less than 50db
9. Equipped with an air inlet filter to ensure the purity of the sample
The dried product has uniform particle size, with over 95% of the dry powder falling within the same particle size range
11. A water cooling device for the spray head is optional to meet the drying process requirements of heat-sensitive materials
12. Nitrogen circulation access to the system is optional to achieve the organic solvent drying process
13. It complies with the EU CE quality certification and operates safely and stably
Application scope
It is suitable for the production of trace amounts of granular powder in laboratories of universities, research institutes and food, medicine and chemical enterprises. It has wide applicability to all solutions such as emulsions and suspensions, and is suitable for the drying of heat-sensitive substances such as biological products, biological pesticides and enzyme preparations. Because the material sprayed out is only exposed to high temperature when it is sprayed into a mist and the heating is instantaneous, these active materials still maintain their active components unchanged after drying.
It is specifically used in the following fields: beverage flavors and pigments, milk and egg products, plant and vegetable extracts, pharmaceuticals, synthetic heat-sensitive substances, plastics, polymers and resins, fragrances, blood products, ceramics and superconductors, biochemical products, dyes, soaps and detergents, food adhesives, oxides, bone meal and tooth powder, etc.
