Product Description

Product Overview

The SZG double cone rotary vacuum dryer is a new generation drying device developed by our factory based on similar domestic product technology. The double cone vacuum has a two-stage elastic connection method of belt and chain, so the equipment runs smoothly. The specially designed tooling fully reflects the good unity of the two shafts,

Both the heat medium and vacuum system use reliable American technology rotary joints. On this basis, we have developed SZG-A, which can achieve both stepless speed regulation and constant temperature control. As a professional drying equipment manufacturer, we serve our customers with over a hundred units per year. Our products range from high-temperature heat transfer oil as the heat medium, medium temperature steam, and low-temperature hot water. When drying viscous materials, our factory will specially design a "copying plate" structure or set up ball bearings inside the tank for you.

Product Features

When oil is heated, automatic constant temperature control is used to dry biochemical products and mineral raw materials, with a temperature difference of ± 2 ℃ between 20 and 160 ℃. High thermal efficiency, more than twice as high as a typical oven. Indirect heating ensures that the material is not contaminated and meets the requirements of GMP. The equipment maintenance operation is simple and easy to clean.

Application scope

Suitable for the concentration, mixing, drying of powders, granules, and fibers in industries such as chemical, pharmaceutical, and food, as well as materials that require low-temperature drying (such as biochemical products). It is more suitable for drying materials that are prone to oxidation, volatilization, heat sensitivity, strong irritation, toxicity, and materials that do not allow crystal destruction.

Working principle

Heat energy (such as hot water, low-pressure steam, or thermal oil) is introduced into a sealed interlayer, and the heat is transferred to the dried material through the inner shell. Under the power drive, the tank rotates slowly, and the materials inside the tank continuously mix, thereby achieving the purpose of enhancing drying. The material is in a vacuum state, and the decrease in vapor pressure causes the water (solvent) on the surface of the material to reach saturation and evaporate, which is promptly discharged and recovered by a vacuum pump. The moisture (solvent) inside the material continuously permeates, evaporates, and is discharged to the surface, and these three processes are carried out continuously, achieving the drying purpose of the material in a very short time.
