Spiral belt vacuum dryer is an efficient drying equipment. The following is a detailed introduction to it:

First, the working principle

The working principle of the spiral belt vacuum dryer is that the spiral belt is used to rotate and lift the material, and at the same time, the heat transfer medium (such as hot water, heat transfer oil, steam, etc.) is introduced into the conical jacket and hollow spiral belt, so that the heated material can be lifted from all sides and fall from the middle, and it can be quickly and continuously turned over. Through vacuumizing in the cylinder, the water vapor is taken away in time, so that the materials can be dried and mixed in a short time.

Second, the characteristics

Efficient drying: spiral belt vacuum dryer adopts jacket and spiral belt internal heating, and the overall heating area increases by about 40%, which improves the drying efficiency.

Forced heat transfer: the equipment can realize the effect of circulating stirring from bottom to top, and can obtain forced heat transfer performance.

Prevention of adhesion: the gap between the single ribbon agitator and the container wall is small, which can effectively prevent the material from adhering to the surface of the container wall.

Convenient unloading: the cone-shaped cylinder structure with small angle is adopted, which makes the unloading speed fast, clean and free of material accumulation.

High hygiene requirements: there is no transmission mechanism in the cylinder, which fundamentally eliminates the material pollution caused by lubricating oil leakage, and the operation is reliable and stable, especially suitable for mixing powder and particles with high hygiene requirements.

Third, the application field

Spiral belt vacuum dryer is especially suitable for process treatment in closed and controllable environment, such as pharmaceutical and chemical fields, additives, extract crystals unstable in air or high temperature and various medical biological processes. In addition, it can also be used for drying powder materials in food, pesticide, metallurgy and other industries.

IV. Technical parameters and models

The technical parameters of spiral belt vacuum dryer include model, specification, capacity, power, etc. The specific parameters vary with the equipment manufacturer and use. The common models are ZZG series and ZXLG series, with specifications ranging from 50L to 5000L and power ranging from 1.5kw to 22kw. Users can choose appropriate models and specifications according to specific requirements and material characteristics.

V. Market price

The market price of spiral belt vacuum dryer varies with brand, model, specification, material and other factors. Generally speaking, the price of domestic equipment is relatively low, while the price of imported equipment is relatively high. The specific price also needs to be determined according to user demand and market competition. Users can obtain detailed quotations by consulting equipment manufacturers or related agents.

VI. Maintenance and Maintenance

In order to ensure the normal operation and prolong the service life of the spiral belt vacuum dryer, users need to maintain the equipment regularly. Specific measures include:

Regularly check whether the fasteners of the equipment are loose, and tighten them in time if they are loose.

Regularly check whether the transmission parts of the equipment are worn or damaged, and replace them in time if there is any abnormality.

Regularly clean up the residual materials and dirt inside the equipment to keep the equipment clean.

Regularly check whether the heating system and vacuum system of the equipment are working normally, and eliminate any faults in time.

To sum up, the spiral belt vacuum dryer has the advantages of high efficiency, energy saving and environmental protection, and has a wide application prospect in pharmaceutical, chemical and food industries.
