Benchtop and floor-standing air blasting oven is one of the most used drying equipment in pesticide factory. Box type drying oven is a small investment, easy operation, convenient variety replacement and small tail gas treatment capacity. Suitable for small batch, regular variety change, intermittent production occasions. However, it belongs to static intermittent drying, the traditional equipment has poor working conditions, large labor intensity and long production cycle. Although the operating temperature is not high, it is easy to overheat the dry material because the material is subjected to the same temperature for a long time. General products after drying but also after crushing, also not suitable for the production of large tonnage products. Box dryer also has two types of parallel flow and through flow. The former is mainly used for drying paste materials, and the flow box dryer is mainly dried by hot air through the surface of wet materials. When the hot air passes through the wet material surface, the surface material is heated and the moisture vaporizes first. Due to the humidity difference inside and outside the material, the internal moisture moves to the outside and vaporizes, repeating the above process to dry the material. Through flow box dryer is hot air vertical through the material, mainly used for block and granular material drying. Compared with the parallel flow box dryer, the drying time is shorter and the production efficiency is higher. Most pesticide plants use the method of placing the tray on the steam pipe, turning the material manually at regular time, and heating and drying under static condition. This method must have high labor intensity, more importantly, the inhomogeneity of material drying is inevitable, the product quality can not be guaranteed, and the energy loss is very large. The thermal efficiency of this box dryer is not more than 20%. In recent years, the drying oven manufacturer have carried on the technical transformation to the box type precision oven, mainly has made the improvement in the following several aspects. First, the tray of box dryer adopts cart type, and multi-layer tray is placed on the cart, which improves the working efficiency and reduces the labor intensity. Secondly, using forced hot air circulation, the temperature in every corner of the dryer is basically the same, which not only ensures the uniformity of moisture and quality of the product, but also greatly improves the working efficiency and thermal efficiency. Although the box drying oven is the original, old drying equipment, but also practical can’t be eliminated, it has other drying equipment incomparable advantages. Therefore, although many new drying devices have been developed, there is still no sign of withdrawal. The automatic temperature regulating system and ventilation system of box dryer should be further developed. The gas relative humidity measuring instrument is installed at the outlet of the gas discharge, and some hot air circulation is adopted to correct its shortcomings as far as possible, so that this old equipment can play a new role.

The processing of many pesticides can’t be separated from drying oven, and the high requirement of pesticide dosage form also brings new development space to air circulation oven. In the past, the pesticide industry mainly use drying oven, drying room and other static drying, then break into powder after drying. Not only the production conditions were very bad, the use of drugs and the effectiveness were limited. Using new drying methods and new drying technology will play a very important role in the development of new pesticide formulations. The characteristics of pesticide drying Pesticide drying and other chemical products drying has many differences. First, the dosage form of pesticide is more, in addition to liquid dosage form, solid dosage form has powder, granular, block, strip, flake. For pesticides, drying is not only evaporation of water, but also the formation of different solid forms in the drying process, but also to ensure the role of drugs, so the drying process is also the process of dosage form manufacturing. Therefore, the drying equipment used is more complex. Secondly, toxic and taste are the basic characteristics of pesticide products, and the safety protection of drying field workers is very important. The discharge of gas during drying operation should also be strictly controlled. For example, efficient herbicide drying, if there is farmland around the production site to ensure the safety of crops. After drying, the economical heat source is chosen as far as possible, especially the pesticide with low added value should control the production cost. There are two main parts of drying, one is the drying of pesticide processing aids and fillers, the other is drying in the preparation process to obtain the final product. Because the moisture content of pesticide products is strict and the moisture content of fillers directly affects the quality of products, the drying of fillers is also an important link in the processing of pesticide powder. Because of the large amount of pesticide, considering the product price, the filler of pesticide powder is mainly clay, clay, kaolin, silica and other minerals. For this reason, the pesticide drying equipment basically uses convection drying, and mainly to rotary dryer, box dryer, airflow dryer, shaft kiln and so on. With the improvement of preparation technology, spray dryer and other equipment began to be equipped in pesticide production. Rotary fast dryer, blade dryer has also been used.

Semiconductor laser is a kind of laser, which is often called high power laser diode. The main working principle is to complete the corresponding laser work with the help of semiconductor material. This is also the origin of his nickname. High power semiconductor lasers are separated by different output power of semiconductor lasers. At present, the research on high power semiconductor lasers is mainly carried out in four aspects: output power, conversion efficiency, reliability and beam quality. In the aspect of output power optimization, inc reasing the number of luminous points and single tube laser optimization is the most widely used output power optimization method of high power semiconductor laser. Single tube laser optimization is one of the effective means. At present, the output power of single tube laser is more than 250000. In the optimization of conversion efficiency, the emphasis is on temperature control, carrier consumption control and threshold consumption control. Reliability is one of the key points of high power semiconductor laser optimization. At present, the main means to improve reliability are to optimize heat transfer structure, improve packaging technology, increase spot size, improve growth (crystal) quality and so on. The application space of high power semiconductor laser is wide, so the research of high power semiconductor laser will be further developed, thus promoting the application development of high power semiconductor laser.

Industrial drying oven: it is composed of stainless steel and cold rolled steel plates, in addition, the oven body is strengthened, the exterior surface is repainted, and the insulation material between enclosure and studio is super glass fiber. The industrial oven is widely used and can dry all kinds of industrial materials. How to make the efficient electric heating system of industrial oven more energy saving? The following small editor to give you a brief introduction. The industrial oven is heated by electric heater. The heating wire usually exposed to air is easy to oxidize because of high temperature and long-term heating, which affects the lifespan. The heater usually uses coil electric heating pipe, that is, the heating wire is located inside the heating pipe. The temperature control instrument of industrial oven is used to control and display the temperature. When the temperature in the oven is lower than the set temperature, the temperature control instrument controls the continuous heating or gap heating of the heater, so that the temperature in the oven can be controlled. The function of the blower is to make the air in thedrying ovenhorizontal (benchtop electric air blast drying oven) or vertical (floor standing air blast drying oven) convection circulation, so that the air in the oven is sent to the electric heater and heated to the studio. The hot air in the studio can heat the wet sample and the moisture will be mixed into the hot air by heating into water vapor.

I. Ventilation Through the convection of air and the outside boring air to communicate, to reduce the indoor and room moisture-proof intention, the way is to open windows or install exhaust fans, window opening time is also fastidious, need to be in the morning 10 to 5 pm this time period, because sooner or later the air is wet, the disadvantage of the seed method is that when the outside air is also wet or rainy, the moisture-proof intention can’t be realized. II. Desiccant Through the purchase of desiccants (such as lime powder, charcoal, chemical moisture absorption products, etc.), the desiccant is placed in the room that needs moisture-proof. After the adsorption function of the desiccant, the water vapor in the air is absorbed, and the air becomes boring. Its deficiency lies in: slow speed, when the boring agent adsorption to saturation state, there is no moisture absorption function, need to often care, to replace. III. Air conditioning When it comes to moisture-proof, many people think that air conditioning can also dehumidify, just use air conditioning to prevent moisture. Indeed, air conditioning now has the function of dehumidification, but dehumidification efficiency is low, only a small range of moisture around the air conditioning. In addition, dehumidification with air conditioning will increase the load of air conditioning and shorten the service life of air conditioning, because the main function of air conditioning is to regulate temperature, and the effect on dehumidification is not obvious, which is why most offices and families install air conditioners. Also buy dehumidifier moisture-proof reason. IV. Dehumidifiers The dehumidifier is a kind of electrical product which specially improves the wet environment, has the computer automatic control function, can separate the water in the air from the air, becomes the water discharge, only needs to put the dehumidifier in the room and the space which needs the moisture-proof, and the humidity can be self-conditioned, can be managed automatically, is also the better moisture-proof method at present.
