Product Introduction
The spray dryer is a widely used process in the liquid forming process and drying industry. It is one of the continuous atmospheric pressure dryers. It has the characteristics of fast heat transfer, rapid moisture evaporation, instant drying time, good product quality, good solubility, and can improve the dissolution rate of some preparations. It is used to produce powder and granular solid products from solutions, lotion, suspensions, and paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product meet the standards, the spray dryer is a very ideal drying equipment.Price of GY-GTGZJ full-automatic 3L experimental spray dryer

Spray dryer is widely used in various fields, and can be used in chemical industry, such as battery raw materials, alkaline dye pigments, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid agents, amino acids, white carbon black, etc. It can be used for plastic resins, such as AB, ABS lotion, urea formaldehyde resin, phenolic resin, urea formaldehyde resin, polyethylene, PVC, etc. Can be used in the food industry, such as high-fat milk powder, gelatin, cocoa milk powder, milk replacer powder, animal blood powder, egg white (yellow) whole egg powder, etc. It can be used for food and plants, such as oats, chicken juice, coffee, instant tea, seasoning spice meat, protein, soybean, peanut protein, hydrolysate, etc. Can be used for sugars such as corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc. Can be used for drying ceramic materials such as alumina, ceramic tile materials, magnesium oxide, *, etc.

Principle of small spray dryer
GY-GTGZJ-3LLaboratory spray dryerIt is the air that passes through the filter and heater, enters the air distributor at the top of the drying tower, and then spirals evenly into the drying chamber. The material liquid is pumped from the material liquid tank to the centrifugal atomizer at the top of the drying tower through a filter, causing the material liquid to spray into extremely small mist droplets. The material liquid comes into contact with hot air in parallel, and the moisture evaporates rapidly, drying it into finished products in a very short time. The finished product is discharged from the bottom of the drying tower and the cyclone separator, while the exhaust gas is discharged by the fan.Price of GY-GTGZJ full-automatic 3L experimental spray dryer

Advantages of spray drying
As long as the drying conditions remain constant, the characteristics of dried products will remain constant. The operation of spray drying is continuous. Its system can be fully automatically controlled. The spray drying system is suitable for drying heat sensitive and non heat sensitive materials. The drying raw material liquid suitable for aqueous solutions and organic solvent materials can be solution, slurry, emulsion, paste or melt, and even filter cake. The spray drying operation is very flexible

UV lamps can also be hung on the ultra clean workbench, but they should be installed outside the lighting lampshade and staggered in the arrangement of the lighting fixtures, so as not to obstruct the lighting during work. If the ultraviolet lamp is installed inside the lighting lampshade (glass plate), it is useless because ultraviolet rays cannot penetrate glass. Its lamp tube is made of quartz glass, not silicate glass.
The vaccination room strives for simplicity, and any items that are not directly related to the work of the room cannot be placed to maintain sterility. The air inside the vaccination room should be isolated from the outside air, and the reserved ventilation ducts should be sealed as tightly as possible. Ventilation ducts can be equipped with upper and lower ventilation windows, with a slightly larger window area that needs to be covered with 4 layers of gauze for simple dust filtration. After a day of work, windows can be opened for sufficient ventilation before being sealed. In short, it is clean, dust-free, and sterile, with fresh air, making it suitable for work. The gauze covering the ventilation window should be changed frequently. However, the above measures are only ideal design schemes and are often not easy to fully implement. In fact, strict aseptic operation procedures are only required. In rooms with open doors and windows, there is a super clean table for protection, and the contamination rate of vaccination is still controllable at a tolerable level in production.
Purification (Purification) of Preliminary Extract Liquid Liquid Distribution Purification Method: Liquid liquid distribution is a commonly used purification method, based on the distribution rule. According to the difference in solubility of pesticides and impurities in different solvents, a non-polar solvent and a polar solvent pair are commonly used for distribution, such as acetone hexane, acetonitrile ethane (petroleum ether), acetone dichloromethane, dimethylformamide hexane, etc. Pesticides are extracted with n-hexane along with fats, waxes, pigments, etc., and then shaken together with a polar solvent such as acetonitrile to separate the pesticides from fats, waxes, pigments, etc. In the food industry, spray drying equipment is a contradiction. It can not only keep the food with good appearance and original nutritional value, so as to produce coffee companion, egg yolk powder, milk powder, soup, juice powder and other products, but also has defects such as large power consumption, large volume, wall sticking and large one-time investment. Under the heavy pressure of environmental protection and people's increasing requirements for food, spray drying equipment needs more efforts to maintain its position in the food industry.
According to the structure of the atomizer, spray drying equipment can be divided into centrifugal type, pressure type and air flow type. Spray dried food can be solution, slurry or paste, but it must be pumped. Food materials need to be atomized before entering the drying chamber for heat exchange. Because the droplets formed by spray are very small, this provides a considerable heat exchange area, enabling the evaporation process to proceed rapidly.
In this way, most of the pesticides are extracted by acetonitrile, and after multiple extractions, the pesticides can be almost completely separated from impurities such as fat, thus achieving the purpose of purification.
Florisil column chromatography method: The Florisil column chromatography purification method has been widely used in pesticide residue analysis, and in multi residue analysis, solvent systems with different polarities are commonly used to wash various pesticides into different elution fractions to separate them into groups. The washing system proposed by MILLS et al. consists of three polar increasing systems: A solution: dichloromethane: n-hexane (1:4), B solution: dichloromethane: acetonitrile: n-hexane (50:0.35:49.65), and C solution: dichloromethane: acetonitrile: n-hexane (50:1.5:48.5), which can separate and isolate some phosphate esters, organochlorine, methyl carbamate, phenyl carbamate, and urea pesticides in fruits and vegetables. THEIR and others use petroleum ether: dichloromethane (4:1); Petroleum ether: dichloromethane (3:3); Dichloromethane: a washing system of methanol (19:1) is used to separate some phosphate esters, organochlorine compounds, methyl amino acid esters, phenyl amino acid esters, and urea pesticides from fruits and vegetables. Huang Shizhong et al. used dichloromethane: petroleum ether: acetone (6:3:1) pre leaching and dichloromethane: petroleum ether: acetone (6:3.5:0.5) leaching to separate 10 types of organic nitrogen from soil and grain, with a recovery rate of 81-103%. The extraction method for pesticide residues is the oscillation rinsing method. The sample to be tested is soaked in the extraction solvent and can be oscillated if necessary to accelerate diffusion. It is suitable for adhering to the surface of the sample
