Introduction: YC-501 micro organic solvent spray dryer (closed spray dryer) uses a menu-based microprocessor controller (7-inch touch screen), which can directly set the inlet temperature, air flow, automatic needle frequency, pump speed, data acquisition and process Monitoring and control. The self-priming peristaltic pump pumps the sample liquid from the container through the nozzle into the drying chamber, while compressing the nitrogen gas from the outer sleeve into the drying chamber to atomize the liquid. The heated nitrogen enters from the upper layer and meets the sprayed liquid particles, and the article begins to dry. The dried powder is separated from the exhaust gas by a cyclone and then enters a collection bottle. The gas stream carrying the organic vapor is cooled down in the heat exchanger, and then the solvent is condensed and recovered in the refrigeration unit, and the clean nitrogen enters the next cycle. Features: 1) It can solve the problem that drying of organic solvent-containing materials in spray drying is difficult. Generally, organic solvents will be inflammable and explosive. The explosion-proof closed laboratory spray dryer can circulate materials in a closed drying system. The contact of organic solvent gas with external oxygen air ensures safe production; 2) It can solve the problem of difficult drying of easy oxide material in raw material production. This technology utilizes the oxidation resistance of inert gas, and the material is dried and transported in the environment of oxidation resistance of closed loop system, which serves as the purpose of isolating oxygen and ensuring The quality of the easy production of oxides; 3) It can solve the problem of poisoning gas pollution in some raw materials production. Some materials or organic solvents will produce toxic gases when vaporized. The inert gas closed loop laboratory spray dryer will seal these toxic gases into the system, and then Road collection can reduce environmental pollution and contribute to environmental protection. The first domestic desktop type: the equipment can be placed on the experimental bench, or placed on the YC-501 of the Yacheng nitrogen circulation system. The equipment is compact and easy to operate; 4) It can be used in aqueous solution and organic solvent: YC-500 laboratory spray dryer is divided into basic type and organic solvent type. The basic type is suitable for spray drying of aqueous solution. After matching YC-501 nitrogen circulation system, it can be upgraded into Organic solvent type, easy to upgrade; 5) YC500 desktop spray dryer is upgraded to organic solvent type, only need to buy YC-501 components: due to budget constraints, many researchers with organic solvent drying requirements can only purchase aqueous spray dryers, but later, I had to buy an organic solvent spray dryer again, which caused a huge waste of research funding. The YC-500 laboratory desktop spray dryer has completely solved this problem. After purchasing the basic model, the researchers only need to purchase the YC-501 nitrogen circulation system to form a closed spray dryer, and the connection is very convenient. When the aqueous solution is dried, the compressed air is used, and when the organic solvent is dried, the nitrogen is used. No need to worry about these problems anymore; 6) Concentric spray head: During the experiment, the new spray head is absolutely not eccentric when atomizing, and will not spray to the bottle wall when spraying, which will affect the recovery rate. The spray head can move up and down to change the atomization position to improve the spray drying effect. It is particularly worth mentioning that the spray head is very adaptable to high-viscosity materials, and the phenomenon of clogging the spray head is rare; 7) Exhaust gas dedusting device: YC-500 standard exhaust gas dedusting device not only reduces environmental pollution, but also effectively increases the yield, especially the yield of difficult to recycle materials; 8) New type of heater: The heating wire of the laboratory spray dryer is easy to blow. The YC-501 effectively solves this problem, and researchers no longer have to worry about the need to replace the heater. Technical Parameters: 1) The equipment is placed directly on the test bench or the nitrogen circulation system device. The system adopts the dual control mode of automatic control and manual control. The color touch screen dynamic display (animation) throughout the experiment process. 2) Inlet air temperature control: up to 250 ° C, outlet temperature: up to 140 ° C 3) Material handling capacity: up to 500ml/h, maximum feeding amount: peristaltic pump adjustable up to 2000ml/h 4) Minimum feed amount: 20mL 5) The spray head is a concentric spray head. When atomizing, ensure that there is no eccentricity and it is sprayed to the side of the bottle wall. After the spray head is installed, it can be moved up and down to facilitate the adjustment of the atomization position to improve the spray drying effect; 6) Color LCD touch screen parameter display: air inlet temperature / air outlet temperature / peristaltic pump speed / air volume / pin frequency 7) Nozzle diameter: 0.5mm/0.7mm/0.75mm/1.0mm/1.5mm/2.0mm optional, and can be customized according to requirements 8) The whole machine is made of stainless steel, the atomization structure of the two-fluid spray, the spray, drying and collecting system is made of high quality SUS304 stainless steel (with observation mirror) 9) Power of the whole machine (including nitrogen circulation system and refrigeration system): 2KW / 220V 10) It can be used for spray drying of aqueous solutions and organic solutions (nitrogen circulation system is required for organic solvents)
