There are many types of industrial drying equipment, because the equipment performance required in different working environments is different. For example, vacuum drying equipment is used for pharmaceuticals because powdery chemicals can cause dust pollution. The equipment designed for the problem; the vertical drying equipment and the horizontal drying equipment are caused by the environment available at work, which are due to various factors in the work or working environment and actual operation. Created a new type of machine, let’s compare the performance of these common drying equipment.
Vacuum dehumidification drying equipment
The main parameter controlled by rapid evaporation of water in the raw material to achieve rapid drying is vacuum; the vacuum drying equipment is placed together with the dehumidifying drying equipment for testing, vacuum drying because the drying principle is to reduce the water at low pressure. The principle of evaporation point. The results show that vacuum drying equipment can save 70%-80% energy. This is mainly because the desiccant of the desiccant drying apparatus consumes a large amount of energy during the regeneration process. The drying time of vacuum drying is usually 1/5-1/6 long-time high-temperature drying of other dehumidifying and drying, which causes hot chemical and physical reaction of raw materials, which causes the quality of materials to decrease, such as fading and melt index to decrease. Affecting the quality of waste products reduces the possibility of material quality degradation.
Taking polycarbon PC drying as an example, the vacuum drying equipment shortens the drying time of the material. Drying at 120 degrees Celsius, under the premise of 0.02% final water content, dehumidification drying usually takes about 4 hours, while vacuum drying requires only 20-25 minutes to dry. This saves the drying time of 3 hours and 35 minutes, and the advantage of vacuum drying equipment in the trial section is particularly obvious! Drying efficiency is of particular importance to precision injection molding manufacturers.
Some resins or high-molecular substances have high sensitivity. If the drying time is too long, stress may occur, leading to baking, embrittlement and discoloration. It is mainly used in the honeycomb type dehumidifying drying equipment series, mainly for moisture absorption. The strong engineering plastics are designed and developed for high-efficiency dehumidification heat pump dehumidification drying equipment. How to strictly control the moisture in the raw materials is the key to processing high-quality plastic products, which are represented by today’s models. The most high-tech Japanese honeycomb fiber-based honeycomb rotor is the core component, so the dry air can easily reach -40 ° C dew point, ideally reach -50 ° C or even lower dew point, and dew point The temperature is stable, ensuring the quality and stability of the formed plastic products. It adopts Japanese PLD temperature control system as standard equipment; it also provides PLC control with LCD touch human-machine interface and dew point meter which can monitor the dehumidification effect of the machine at any time. The maximum dry air volume of this product can reach 3000m3/hr.
Box drying equipment
The box type drying device puts the material to be dried into the movable tray. When the power is turned on, the strong wind wheel starts to force the air entering from the air inlet to blow into the electric heating tube, and the air is heated and heated by the electric heating tube and passes through. The perforated partition wall is evenly blown to the material, and the air carrying the moisture will be taken out of the oven by the top exhaust fan.
Repeated circulation in this way achieves the effect of moisture removal and drying. It is widely used for the drying of any plastic raw materials, and can simultaneously dry materials of different materials and colors. It is especially suitable for drying materials with high temperature accuracy, low dosage and various colors. It is also suitable for preheating or drying treatment in food, pharmaceutical, electronic plating and other industries; using PI temperature control to precisely control drying temperature; integrating temperature and time control, facilitating drying parameter setting of various materials; high quality thermal insulation material High sealing design avoids unnecessary energy loss; adjustable air inlet; motor overload protection, phase sequence protection.
Vacuum drying equipment
Also known as vacuum conveyor, vacuum drying equipment is a dust-free and closed pipeline conveying equipment that transports particles and powder materials by means of vacuum suction. The pressure difference between vacuum and environmental space is used to form the gas flow in the pipeline and drive the powdery materials. Exercise to complete the delivery of the powder. Because it is a pipeline transportation, it takes up a small space and can complete the powder transportation in a narrow space, so that the space in the work space is beautiful; especially, it is not limited by the long distance. At the same time, the vacuum feeder can reduce the labor intensity and improve the working efficiency. It is the first choice for most powder material transportation methods. Its main application areas are chemical, pharmaceutical, food, metallurgy, building materials, agricultural and other light and heavy industries. Vacuum feeder is mainly used to transport powder and granular materials, such as raw material powder, chemical powder, metal oxide powder, explosive powder; capsules, tablets, pills, small food pellets, explosive particles, etc.; not suitable for conveying Too moist, sticky, heavy material.
In summary, industrial drying equipment is widely used in various industries. They are constantly developing and improving in daily production. In the current technological development, many different working environments have been added.
