How to remove impurities from wheat by flour machinery

Flour machinery needs to go through a step in the process of producing high-quality white flour, that is: impurity removal! Flour machinery can only produce higher-quality flour by applying reasonable impurity removal technology to wheat. So how should the flour mill remove wheat impurity correctly and reasonably?

　　①In order to ensure the purity of the milled wheat, all kinds of impurities in the raw materials should be removed, but the focus of removal is all kinds of dust mustard impurities, especially various inorganic impurities that have the greatest impact on the production and product purity.
　　②When arranging the impurity removal sequence, consider first removing the large dust mustard impurities that are directly harmful to production, and then removing other mixed and adherent impurities. First, remove impurities that are very different from the technological characteristics of wheat, so that the types and quantities of impurities in the raw materials are greatly reduced, and then treat the impurities that are not much different from the technological characteristics of wheat.
　　③For impurities that are two or more different from wheat, simpler methods should be used to remove them. For example, for sand and gravel whose grain size is obviously larger or smaller than wheat grains, the effect of screening is better than that of stone removing machine.
　　④ Side-by-side impurities with a suspension speed similar to that of large-grain wheat are difficult to remove, such as side-by-side mud with a small particle size. These impurities need to be removed by selection or comprehensive methods.

      

The above four are the principles of the flour machine for removing impurities from wheat. I hope that all users of flour machines can learn and master certain skills for their own use!

Lubrication is very important for pellet machine operation

Granulator is used to develop wet powder into the desired particles, but also can crush the block dry material to the desired particles. The main feature is that the screen mesh is easy to assemble and disassemble, but also appropriate adjustment of tightness. Hexagonal drum is easy to disassemble and clean. Mechanical transmission system is enclosed in the body, and with lubrication system, smooth operation of the whole cattle feed business machine. The following is for you to introduce the particle machine parts lubrication.

1. The box part of the cattle feed pellet machine is equipped with an oil gauge, which should be refueled once before starting. It can be added halfway according to the temperature rise and operation of each bearing.
2. The worm gear box must be stored for a long time, and the oil level is that the worm gear all invades the oil. If often used, it must be replaced with new oil every three months.
3, when the machine refueling, do not make the oil spill out of the cup, not to flow to the poultry feed making machine around and on the ground. Because oil is easy to make the material pollution, affect the quality of products.

ABC Machinery Charcoal machine equipment

The raw materials of the charcoal making machine are very important. We must ensure the quality of the charcoal, it is necessary to make a good charcoal rod. In addition to the quality of the stick depends on the charcoal machine equipment and process, it also depends on the amount of moisture in the raw material. Generally, the moisture content of the raw materials is required to be less than 12%, but also greater than 6%. Therefore, our initial task is to ensure the moisture content of the raw materials.

The raw material rod making is finished in the forming machine (or sawdust briquettes making machine). There are three heating rings outside the molding cylinder of the molding sawdust briquette press, which can increase the temperature of the molding cylinder to about 350°C.

Let's analyze the relationship between carbon and temperature through raw materials, molding, carbonization, and products. The whole process of burning charcoal is dealing with heat. The amount of heat can be measured by a specific "temperature".

In order to ensure that the charcoal rod has a high density, a lubricating surface, and no significant cracks. We can select the appropriate molding temperature according to the variety of raw materials and moisture content. Its unevenness must be determined through field experiments. Generally speaking, if we assume that the screw propeller is qualified and the moisture content of the raw material is between 6-12%, then we can control the final temperature of wood chips, wood sawdust, wood shavings and bamboo raw materials at 260-320℃ between.

Is the technique of making charcoal sticks important?

 The machine-made charcoal machine requires a set of equipment to make charcoal, and secondly, it requires the cooperation of manual technology to produce qualified charcoal. How to make briquettes from sawdust by the charcoal machine.
Machine-made charcoal machine makes charcoal equipment: grinder, dryer, rod making machine and carbonization furnace.

 

Charcoal machine production process:
　　1. First, check whether the raw material is particles below 1cm. If not, use a grinder to crush the raw material
　　2. Secondly, check whether the humidity of the raw material of the charcoal making machine after crushing is greater than 12%. If it is greater than that, the raw material needs to be dried.
　　3. Then the pulverized and dried charcoal machine equipment raw materials are processed into charcoal rods (semi-finished products) through a wood chip briquette maker at high temperature and high pressure.
　　4. Put the semi-finished carbon rods into the carbonization furnace for carbonization, and finally form machine-made charcoal (machine-made charcoal machine equipment finished product).
　　Why can't machine-made charcoal be made like traditional charcoal? Because machine-made charcoal is produced according to specifications, the produced charcoal is of high quality, high quality, fast charcoal production, and environmentally friendly. However, the production of machine-made charcoal requires rod making technology and carbonization technology.

The principle of the briquette making machine is to plasticize the raw material at high temperature, and then press it into a hollow outer square or hexagonal rod shape after high pressure. In this process, the moisture content of the raw material must reach 8%-12%. If the moisture content is high, the rod will spread out in a blooming shape. If the moisture content of the raw material is low, the rod will be cracked and not strong enough. The rod-making technology must ensure the size and moisture of the raw materials. 1. The particle size of the raw materials is 5-8mm and the moisture of the raw materials is 15-18%. Therefore, the machine-made charcoal machine-made rod technology is very important.

What is the small wood pellet machine and the raw materials

 1. What is a small wood pellet machine:
The small poultry feed making machine is a special mechanical equipment that converts materials (sawdust, corn stalks, peanut shells, rice straw, cotton stalks, branches, edible fungus waste, cow dung and other raw materials) into high-density, combustible and high-quality pellets.

2. Biomass raw material for small cattle feed business pellet machine:
Including plants, animals and microorganisms. Such as straws, trees and other lignocellulose (lignin for short), scraps of agricultural products processing industry, agricultural and forestry wastes, and livestock manure and wastes in the production process of animal husbandry.
Biomass raw materials contain cellulose, hemicellulose and lignoscine. Because the structure is relatively loose and the density is low, when subjected to external force, the raw materials will undergo the stages of rearrangement, mechanical deformation, and plastic deformation. Inelastic or viscoelastic cellulose molecules are entangled and twisted, which reduces the volume and increases the density. Big.

The thoroughfare of small wood pellet machine
• Civil heating and life energy use; high combustion utilization rate, easy to store
• Biomass industrial boiler; as the main fuel for industrial boilers, it can replace coal and solve environmental pollution.
• Power generation: can be used as a fuel for thermal power generation.

Machine charcoal machine production line

How to make briquettes from sawdust? Machine charcoal machine production line equipment is composed of: pulverizer, storage bin, roller screen, belt conveyor, sawdust dryer, cold material system, screw feeder, briquette making machine, steel mesh conveyor, environmental protection carbonization furnace and other equipment.

 

1. Pulverizer: For machine charcoal, the size of raw materials should be below 3MM. In addition to sawdust and rice husk, other raw materials need to be processed by crusher first.

2. Roller screen: when the material enters the roller device, due to the tilt and rotation of the roller device, the material on the screen surface turns and rolls, so that the qualified material (the product under the screen) is discharged through the sieve of the outer circle of the roller, and the unqualified material (the product on the screen) is discharged through the end of the roller. Because of the material in the roller, roll, so that the material stuck in the screen hole can be ejected, to prevent the screen hole blocked. The sawdust drum screen is mainly used for the screening of raw materials in the production mechanism of charcoal making business machine.

 

3. Belt conveyor: it is to transport the screened sawdust to the sawdust dryer, with strong conveying capacity, long conveying distance, simple structure and easy maintenance, which can conveniently implement programmed control and automatic operation. The continuous or intermittent movement of the conveyor belt is used to transport items of less than 100KG or powdery or granular items. Its operation is high-speed, stable, low noise, and can be transported uphill or downhill.

4. Dryer: Before rod making, the humidity of raw materials is also strictly required, which cannot be more than 12%. If it is more than 12%, the raw materials should be dried.

5. Cooling material system: This system is the sawdust cooling treatment system after drying the dryer.

 

6. Screw divider: This equipment is used in the transportation of sawdust or fine particle materials, which needs to carry out quantitative split control on two or more branches. The screw divider can realize the proportional control of two or more channels of material flow and satisfy the arbitrary proportional distribution of material flow. It works under the ideal condition.

7. The briquetting machine for sale: the raw materials are crushed and dried, and the next stage is the rod making stage. The crushed and dried raw materials are processed into carbon rods (semi-finished products) through the wood chip log making machine at high temperature and high pressure. The bagasse briquettes machine can make carbon rods into hollow wage rods of 50MM, 60MM, 70MM, 80MM and 90MM according to customer requirements.

8. Steel mesh conveyor: This conveyor is used for conveying semi-finished mandrel produced by multiple rod making mechanisms.

 

9. High temperature carbonization furnace: the made salary rod is put into the carbonization furnace, through dry distillation or spontaneous combustion into the finished charcoal. The steam (white smoke) generated by the drying of the upper carbonization tube of the carbonization furnace is discharged; Coking furnace bottom coking tube coking produce gas, open the combustible gas valve, wait until nearly invisible when the smoke flue gas produced in coking process has been fully recycling, recovery of flue gas by spraying, cooling, purification process into combustible gas enters into the bottom of coking furnace informed for secondary combustion, then close the gasifier. In this way, the self-generated gas can be used to burn the self-generated gas to achieve the effect of energy saving; The whole process can be continuous carbonization production, pollution-free smoke emission, extremely environmental protection, meet the national exhaust emission standards.
