Details of the dry granulator tableting method
2018 / 06 / 25
The dry granulator belongs to a kind of granulator and has many granulator manufacturers. The tableting method of a dry granulator is to uniformly mix powders of pharmaceuticals and auxiliary materials into a large sheet or a plate. The method of smashing into particles of the desired size. This method relies on the compressive force to generate binding force between molecules. The preparation method includes a tableting method and a rolling method. The dry granulation tableting method is often used for heat-sensitive materials and drugs that are easily decomposed when exposed to water. The method is simple, labor-saving and time-saving. The process flow of Wenzhou dry granulation machine manufacturers is as follows: Drugs + accessories → smashing → sifting → mixing → briquetting → smashing → whole-grained → mixing → tableting dry granulator manufacturers' attention to the dry granulator pressing method Note 1, content must be determined after mixing. 2. The properties of drugs and excipients should be similar, so that uneven mixing can be avoided. Because the material's bulk density, particle size distribution and other physical properties are similar when the mixing uniformity is good, especially when the main drug content is small, the finished product needs to do the content uniformity, if the mixture is not good, the problem is big. 3, the incompatible lubricant is added last. Note that be sure to wait for the other dressings to mix evenly, then add the incompatible lubricant, and control the mixing time, otherwise it will affect the disintegration and dissolution. 4, when doing prescription design, we must follow the first small test and then the pilot, and finally the principle of large-scale production. 5, special attention must be paid to various abnormal conditions when pressing tablets. During the tableting process, due to equipment vibration and other reasons, the phenomenon of film slivers, poor uniformity, poor hardness, etc., may be tr

Dry granulator special pigment production process and use characteristics
2018 / 06 / 24
The material is forced by the mechanical pressure of the dry granulator and the mechanical pressure is used for compression molding. No humectant can be added and the purity of the product is guaranteed. The dry powder is pelletized directly without subsequent drying process, which is more conducive to the convergence and transformation of existing production processes. Various dry powder materials are added from the top of the equipment. After degassing and spiral preloading, two equal rollers are pressed. The rollers are rotated relative to each other and the material is forcibly fed between the two rollers. The rollers nip the material into the nip for compression. The material passes through the compression zone. Afterwards, the material's surface tension and gravity cause it to escape naturally. The finger sticks after being taken out enter the smashing machine and are broken by the rotating knife row. The broken material enters into the whole slicing machine and the granules and part of the powdery materials enter the vortex sieve to be sieved through the rolling knife row. The qualified product is sent to the finished product warehouse through the conveyor. Unqualified materials are fed back to the raw material bin for secondary rolling by the conveyor. The size of the pressing force can be adjusted by the pressure of the hydraulic cylinder according to the needs of the granulation operation. By changing the groove shape of the roller surface, sheet, strip, and flat ball materials can be obtained. The high particle strength and the increase in bulk density are more pronounced than other methods of granulation. Particularly suitable for occasions that increase the product's bulk density. The dry granulator special pigment has compact structure, easy maintenance, simple operation, short process flow, low energy consumption, high efficiency, low failure rate, suitable for a wide range of raw materials, and roller pressure can be freely adjusted according to diff
Dry powder granulator processing feed to avoid animals picky eaters
2018 / 06 / 24
The dry powder granulator feeding structure plays a decisive role in the dry-roll forming of the drug. The domestic feed system generally adopts special-shaped unequal-distance screw to feed directly, and can give a certain pre-pressure to the feed screw during the feeding process, so that the hardness and thickness of the pressed material are ensured, so that the pressed medicine sheet meets the required requirements. The key to the dry powder granulation system is to crush and granulate the sheet formed by rolling. After obtaining the pellets with uniform particles and high yield, the company uses the first to break the pellets and then rolls it through the drum. The granulation structure is pressed onto the screen. Can greatly improve the production efficiency of the finished product. The use of dry powder granulation pellet feed has many advantages; 1. It can avoid animals picky eaters. Formulated feed has a variety of raw materials, nutrition, comprehensive, can prevent animals from the powder to choose their favorite, refused to intake of other ingredients phenomenon. Because the pellets of the dry granulator can maintain homogeneity during storage and feeding, it can reduce feed losses by 8% to 10%. 2. Avoid automatic classification of feed ingredients and reduce environmental pollution. In the process of powder storage and transportation, due to the different volume and quality of various powders, it is easy to produce grading. After the granules are made, there is no grading of the feed ingredients, and the granules are not easy to dust. In the feeding process, the granules are less polluted by air and water than the powder. 3. The feed rate is high. During the process of dry granulation, due to the combined action of moisture, temperature and pressure, some physical and chemical reactions occur in the feed to gelatinize the starch and enhance the activity of the enzyme, enabling the fed animal to digest the feed more efficiently and convert it into Increas

Environmental Engineering Petrochemical Sludge Paddle Dryer
2018 / 06 / 19
Petrochemical sludge refers to the sludge from the grease trap, flotation tank scum, and bottom mud of crude oil tanks during the refining process. It is commonly known as [three muds". These oily sludges are of different composition and usually contain oil. Between 10% and 50%, the moisture content is between 40% and 90% with a certain amount of solids. Because petrochemical sludge causes serious environmental pollution to nature, it is one of the major pollutants of petrochemical enterprises. Our company has more than 20 years of experience in manufacturing drying equipment. According to this environmental protection issue, our company designed and manufactured a special paddle dryer for petrochemical sludge. The dryer is a conduction heating low speed stirring dryer. The heat medium flows through the blade through the hollow shaft, and the heat transfer area per unit volume is large. The heat medium can be water vapor or liquid type, such as hot water, heat transfer oil and the like. Indirect conductive heating, without carrying air to take away heat, heat is used to heat the material. The heat loss is only through the body heat insulation layer to the environment. The wedge blade heat transfer surface has a self-cleaning function. The relative motion of the material particles and the wedge-shaped surface creates a scrubbing action that can wash away the adhered material on the wedge surface so that a clean heat transfer surface is maintained during operation.
Quality control during drying of wood
2018 / 06 / 19
The basic principle of improving the drying speed of trees under the premise of ensuring quality. The requirement for drying quality is that the moisture content and dryness uniformity of dried wood can ultimately meet the requirements of the processing technology; the integrity of the wood is maintained, no impermissible defects in the process specification do not occur, and the nature of the wood is not changed. Drying equipment rate per unit of wood moisture content is lower. Faster drying (or shorter drying cycles) requires less investment in drying equipment and lower drying costs. During the wood drying process, the corresponding drying room must be adapted to the change in relative humidity during the different drying stages, and the relative humidity change process or the basis for the development of drying. Different tree species, different thicknesses of wood drying standards, generally divided into two categories, drying time and dry moisture content. According to the time and the operation stage before and after the water-cut drying stage, it belongs to the fluctuation stage of the water-containing stage and the half-wave drying reference. The choice of whether the drying benchmark is appropriate has a direct effect on the yield and the quality of wood drying

How to choose the right drying equipment?
2018 / 06 / 19
Drying operation is a relatively complicated process, and many problems cannot be solved theoretically. It requires experience. The types and types of dryers are also numerous, and the nature of the materials determines the dryers to which they are applied. Intermittent operation dryers have low production capacity, bulkiness, and the material layer is stationary, and are not suitable for the requirements of modern large-scale production. They are only suitable for drying small batches or varieties of products. Intermittently operated dryers have gradually been replaced by continuously operating drying equipment. The continuous operation of the dryer can shorten the drying time, improve product quality, stable operation and easy control. When selecting a dryer, first select several available dryers according to the nature of the material to be dried and the process requirements, then through the economic accounting of the selected dryer's capital costs and operating costs, determine a most suitable drying after comparison.

Flash dryer anti-corrosion process and equipment advantages
2018 / 06 / 15
The flash dryer is used to mix and crush the bulk wet material and ensure that the particles do not stay too long in the high temperature zone of the drying chamber. Therefore, the stirring leaves and the bottom of the chamber and the wall of the chamber should have a reasonable clearance, and the rotational speed of the stirring should also be reasonably selected. There is a good seal between the agitator shaft and the bottom of the drying chamber. The classifier is a perforated ring, similar to an orifice flowmeter, but with an angle, the size and height of the hole diameter depends on the distribution of product particles. When the height is constant, the smaller the hole diameter, the finer the product particle size, the more the flash drying. The addition of a grading ring in the cylinder is one of the focuses of the third-generation product new technology development developed by Anhai Dano. It is very important to control the particle size of the product and greatly improves the product qualification rate. Rotary flash dryers are used to dry the moisture outside the material. The wet material is separated from the heated air stream through the drying air duct of the flash drying apparatus and drying takes place between seconds. Rotary flash dryers are not used in many industrial fields, including foods, chemicals, minerals, and polymers. The combination of materials is also common, including powders, lumps, granules, flakes, pastes, and gels. In the case of slurries, pastes, or viscous materials, backmixing of dry and wet materials is required. The flash dryer drying chamber is equipped with a grading ring and a swirling sheet, and the material fineness and the final moisture are adjustable. (For example, the final moisture of calcium carbonate can be adjusted to ≤0.1%) Compared with other drying methods, the specific gravity of the material can be effectively increased. In the drying chamber, the gas velocity is high in the circumferential direction and th
