Overview

Due to the potential explosion and flammable danger, spray drying of flammable and explosive organic solvents has always been difficult and prohibited. However, in many important new technical fields of research and application, there is an urgent need for spray drying or granulation of organic solvents. In response to this challenge, Shanghai Yacheng successfully launched a laboratory closed spray dryer suitable for organic solvent drying. For most organic solvents currently used in the laboratory, YC-018A laboratory closed cycle organic solvent spray dryer can dry safely and effectively!

Product Details

1、 Working principle

YC-018A Laboratory Closed LoopOrganic solvent spray dryerUsing a menu microprocessor controller (7-inch touch screen), the inlet temperature, air flow rate, automatic needle frequency, and pump speed can be directly set to achieve data acquisition, process monitoring, and control. The self-priming peristaltic pump enters the drying chamber from the container through the nozzle, and the compressed nitrogen enters the drying chamber from the outer casing to make the liquid particles. The heated nitrogen enters the drying chamber from the upper layer and meets the liquid particles after spray, and the articles begin to dry. The dried powder particles are separated from the exhaust gas through the rotary air separator and enter the collection bottle. The air flow containing organic steam is cooled down in the heat exchanger, and then the solvent is condensed and recovered in the refrigeration device. The clean nitrogen enters the next cycle.

2、 Scope of application

YC-018A LaboratoryOrganic solvent spray dryerIt is mainly suitable for the production of trace particle powders in universities, research institutes, and laboratories of food, pharmaceutical, and chemical enterprises. It is suitable for aqueous solutions and most organic solutions because the lowest inlet temperature of aqueous solutions is 105 ° C, and the lowest temperature of organic solvents can reach 60 ° C depending on their boiling points. Therefore, it is suitable for drying thermosensitive materials such as biological products, biological pesticides, enzyme preparations, etc.

3、 Main features

1) YC-018A can solve the problem of difficult drying of materials containing organic solvents in spray drying. Generally, organic solvents are flammable and explosive. The explosion-proof closed laboratory spray dryer enables materials to circulate in a closed drying system, which can avoid the contact between organic solvent gas and external oxygen and air, ensuring safe production;

2) YC-018A can solve the problem of difficult drying of easily oxidizable materials in raw material production. This technology utilizes the antioxidant properties of inert gases to dry and transport materials in a closed-loop antioxidant environment, serving the purpose of isolating them from oxygen and ensuring the quality of easily oxidizable material drying production;

3) YC-018A can solve the problem of toxic gas pollution in some raw material production. Some materials or organic solvents will produce toxic gas during gasification. The spray dryer in the inert gas closed cycle laboratory will seal these toxic gases in the system and collect them in the next process, which can reduce environmental pollution and help environmental protection.

4) YC-018A is easy to operate: the control system adopts PLC automatic control, one click startup, color touch screen operation. During the experiment, experimental parameters such as feed rate, inlet air temperature, air volume, needle frequency, etc. can be changed in real time according to experimental needs, making it convenient for users to use;

5) YC-018A runs stably: The core components of the equipment, such as the touch screen, fan, heater, and control system, are all imported equipment, ensuring the stability and reliability of the equipment operation;

6) YC-018A is convenient for material preparation: the minimum material required is only 20-30 ml, which is conducive to the processing and preparation of small samples, but the maximum processing capacity can reach 1500ml/H, and the processing of large amounts of materials is also extremely fast;

7) YC-018A adopts concentric spray head: during the experiment, the atomization is absolutely not eccentric, and it will not affect the recovery rate when spraying spray to the bottle wall. The spray head can move up and down to change the atomization position, so as to improve the drying effect of spray;

8) Temperature protection: When the experiment ends, the heater temperature*High, the fan needs to continue working to reduce the internal temperature to ensure the safety of the equipment. The YC-015A program can automatically control the operation of the fan. Even if the operator makes a mistake, the fan cannot be turned off until the system temperature drops to the default safe state, and the fan will automatically shut down;

9) Durable fan: The wind is blown out by the positive pressure of the fan in the same direction as the material, and all materials do not come into contact with the fan. The fan will not be contaminated and is durable. The fan is made of corrosion-resistant materials to ensure that it will not be corroded by organic solvent vapors;

4、 Technical parameters

1) Color touch screen operation control, fully Chinese operation interface

2) Feed quantity: maximum 3000mL/H

3) Color touch screen parameter display: inlet temperature/outlet temperature/peristaltic pump speed (controlling material flow)/oxygen concentration

4) The spray head is a concentric spray head. During atomization, ensure that there is no eccentricity that causes the spray to one side of the bottle wall. The spray head can move up and down after installation to facilitate the adjustment of the atomization position and improve the drying effect of spray;

5) The entire system is in a closed state, with online monitoring of oxygen concentration. Once the oxygen concentration in the system reaches 2.5%, the system will automatically shut down and sound an alarm.

6) Nozzle diameter: 0.7mm 1mm 1.5mm 2mm optional, and can be customized according to customer requirements, suitable for various materials and different powder particle size requirements

7) Inlet air temperature control: 60 ℃~280 ℃

8) Timely regulation of PID constant temperature control technology, heating and temperature control accuracy: ± 2 ℃

9) Nitrogen containing circulation system and solvent online recovery system

10) Optional low-temperature cooling circulation pump for low boiling organic solutions
