QG, GFF, JG series pulse airflow dryer

detailed explanation

Features:

The QG series pulse air flow dryer is a large-scale drying equipment that adopts the principle of instantaneous drying. It uses the rapid movement of heat carrying air to drive wet materials and suspend them in the hot air. This strengthens the entire drying process and improves the speed of heat and mass transfer. The non bound moisture of the materials dried by air flow can be almost completely removed, and the dried materials will not produce deterioration. The output can be significantly improved compared to general drying machines, and users can achieve high economic benefits in the short term.

Suitable materials:
This type of equipment is suitable for a wide range of materials, in addition to the materials mentioned in the basic type, including methaqualone, A.B.C. intermediates, A.B.S resins A．S．C、 White carbon black, benzothiazolone, tea meal, oxalic acid catalyst, promoter m.d.m, catalyst, precipitated carbon powder, acetaminophen, p-aminosalicylic acid, Doraemon, phthalic acid, diethylammonium, titanium dioxide, activated carbon, sodium fluorosilicate, fluorite ore, silica gel powder, synthetic resin, calcium phosphate, polypropylene resin, aureomycin, sodium pyrosilicate, coffee grounds tetracycline, ferric oxide, calcium carbonate, corn protein, iron oxide, gypsum retarder, etc.

Key recommendation: Used for drying wood flour, sawdust, rice bran, and bran

The above-mentioned materials have special characteristics: light density, difficult to add, flammable, and explosive. In response to this situation, our company's technical department has developed a new type of airflow dryer, which improves the feeding form on the basis of the original airflow dryer and solves the "bridging" phenomenon. Innovatively improved the cyclone separator, solving the problem of material rolling and not discharging. System integration, advanced control, and over temperature alarm interlock to shut down the heat source effectively solve the problem of combustion and explosion caused by high temperature.

Technical Specifications:

Note: Some parameters may be adjusted according to different materials during design, and the design shall prevail.

QFF series airflow dryer

Principle:
The design of the bottom enhancer is unique, with diamond shaped stirring teeth that achieve low wind resistance. It is placed inside a conical hopper with a moving blade and a fixed blade, resulting in significant crushing effect. The falling agglomerated material is quickly crushed into powder particles suitable for airflow drying. Another main function of stirring is to disperse the material, increasing the contact area with the high-speed hot air coming in from below the hopper. As a result, a strong heat and mass transfer fluidized bed is formed in the hopper area, and most of the moisture is dried in the hopper area. As the drying process progresses, the lighter and finer dry material is significantly affected by the airflow, rising together with the airflow and further drying, before coming out of the top of the drying tower and entering the material collection system.

Suitable materials:
This machine is particularly suitable for processing wet materials with high moisture content in paste like form, as well as materials that cannot be dried by other airflow drying methods. It is suitable for filter cakes, paste like products with certain viscosity, and products that require powder as the final product.

Technical Specifications:

Note: 1. Water evaporation rate refers to the amount of water evaporated per hour at an inlet temperature of 180 ℃ and an outlet temperature of 80 ℃; 2. In addition to the above models, special designs can be made for users. 3. The above installed capacity is the standard matching, and the power may vary according to different materials.
