SZG series double cone rotary vacuum dryer

Overview

SZG double cone vacuum dryer is a new generation drying device developed by our factory in combination with similar domestic product technology. The double cone vacuum adopts a belt chain elastic connection method, so the equipment runs smoothly. The specially designed process fully reflects the good concentricity of the two shafts, and reliable mechanical seals or rotary joints are used for the heating medium and vacuum system. On this basis, we developed SZG-A, which can perform both stepless speed regulation and constant temperature control.

As a professional drying equipment manufacturer, our products range from high-temperature heat transfer oil as the heat medium, medium temperature steam, and low-temperature hot water. When drying sticky materials, our factory will specially design a "board copying" mechanism or set up rolling balls in the tank for you.

Working principle

Heat energy (such as hot water, low-pressure steam, or thermal oil) is introduced into the enclosed interlayer, and the heat is transferred to the dried material through the inner shell.

Under power drive, the tank rotates slowly and the materials inside the tank continuously mix, thereby achieving the goal of strengthening drying.

The material is in a vacuum state, and the decrease in steam pressure causes the water (solvent) on the surface of the material to reach a saturated state and evaporate, which is promptly discharged and recycled by a vacuum pump. The water (solvent) inside the material continuously permeates, evaporates, and discharges to the surface, achieving the drying goal in a short period of time.

Adapt to materials

Suitable for the concentration, mixing, drying, and low-temperature drying of powder, granular, and fiber materials 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 the drying of materials that are prone to oxidation, volatilization, heat sensitivity, strong stimulation, toxicity, and materials that do not allow the destruction of crystals.

Performance characteristics

When heating oil, automatic constant temperature control is used to dry biochemical products

For mineral raw materials, the temperature can range from 20 to 160 ℃.

High thermal efficiency, more than twice that of a typical oven.

Indirect heating. The material will not be contaminated and meets the requirements of "GMP". The equipment maintenance operation is simple and easy to clean.
