Summary

　　The disc continuous dryer is an efficient conductive continuous drying equipment. Its unique structure and working principle determine its high thermal efficiency, low energy consumption, small footprint, simple configuration, convenient operation and control, and good operating environment. It is widely suitable for drying operations in industries such as chemical, pharmaceutical, pesticide, food, feed, and agricultural by-product processing. Highly praised in various industry usage practices. Mr. A produces three types of products: atmospheric pressure, sealed, and vacuum, with four specifications of 1200, 1500, 2200, and 3000. There are A (carbon steel), B (partially uniform stainless steel in contact), and C (steam pipelines are added on the basis of B. The main shaft and bracket are made of stainless steel, and the cylinder and top cover are lined with stainless steel). Three types of materials, with a drying area of 4-180 square meters, a series of hundreds of models of products, and supporting auxiliary equipment, can meet the needs of users for drying various materials.

Principle

　　The wet material is continuously added to the first layer of drying plate on the upper part of the dryer by the feeder, and the rake arm with rake blades rotates to continuously flip the material. The material flows through the surface of the drying plate along an exponential spiral, and the material on the small drying plate is transferred to the outer edge and falls to the outer edge of the large drying plate below. On the large drying plate, the material moves inward and falls into the next layer of small drying plate from the middle discharge port. The large and small drying plates are arranged alternately up and down, allowing materials to continuously flow through the entire dryer. The middle drying plate is filled with heating medium in the form of saturated steam, hot water, and thermal oil. The heating medium enters from one end of the drying plate and exits from the other end. The dried material falls from the last layer of the drying plate to the bottom layer of the shell, and is finally transported by the rake blades to the discharge port for discharge. Moisture overflows from the material and is discharged through the moisture discharge port located on the top cover. The moisture in the vacuum disc dryer is extracted through the vacuum pump port located on the top cover. The dry materials discharged from the bottom layer can be directly packaged. By equipping auxiliary machines such as finned heaters, solvent recovery condensers, bag dust collectors, dry material backmixing mechanisms, and induced draft fans, the production capacity of drying can be improved. Drying paste like and heat sensitive materials can facilitate solvent recovery and allow for pyrolysis and reaction operations.

Application

★ Inorganic industrial products

★ Medicine and food

★ Feed and fertilizer

Characteristic

Easy regulation and strong applicability

★ By adjusting the thickness of the material layer, spindle speed, number of rake arms, rake blade form and size, the drying process can be optimized.

★ Each layer of drying plate can be separately fed with hot or cold media to heat or cool the material, and the temperature control of the material is accurate and easy.

★ The residence time of materials can be accurately adjusted.

★ The material flow direction is single, without back mixing, and it is dry evenly, with stable quality, and no need for mixing.

Simple and easy to operate

★ The operation of driving and stopping the dryer is very simple.

★ After stopping feeding, the rake blades after conveying the material can quickly empty the material in the dryer.

★ Through the special large-sized inspection door mirror, the equipment can be carefully cleaned and observed.

Low energy consumption

★ The material layer is very thin, the spindle speed is low, and the power required for the material conveying system is low, resulting in low power consumption.

★ Drying through heat transfer has high thermal efficiency and low energy consumption.

Good operating environment, recyclable solvent, and dust emission meets requirements

★ Normal pressure type: due to the low air flow speed in the equipment and the low humidity distribution in the equipment, it is difficult for the dust to float to the top of the equipment, so there is almost no dust in the tail gas discharged from the top humidity outlet.

★ Sealed type: Equipped with a solvent recovery device, it can conveniently recover organic solvents from wet gas. The solvent recovery device is simple and has a high recovery rate. For flammable, explosive, toxic, and oxidizable materials, nitrogen can be used as a moisture carrying gas for closed-loop circulation, ensuring safe operation. Especially suitable for drying flammable, explosive, and toxic materials.

★ Vacuum type: A disc dryer operated in a vacuum state, especially suitable for drying heat-sensitive materials.

Easy installation and small footprint

★ The dryer is delivered as a whole and transported as a whole. It only needs to be lifted in place, making installation and positioning very easy. Due to the layered arrangement and vertical installation of the drying tray, even if the drying area is large, the floor area is very small.
