Material continuous negative pressure centrifugal separation drying device

Abstract

The invention discloses a material continuous negative pressure centrifugal separation drying device, which comprises a static separation basin body, a dynamic separation basin body, a dynamic sealing device and a negative pressure liquid storage tank. The dynamic separation basin body is arranged in the static separation basin body coaxially, opening ends of the dynamic separation basin body and the static separation basin body are matched with the dynamic sealing device in sealing mode, and a feeding end is matched with a material conveying device. A material discharging pipe is arranged at the bottom of a rear end of the static separation basin body and communicated with the negative pressure liquid storage tank. Under a negative pressure working condition, a horizontal structure is adopted to match with a dispersing device of materials, the materials are completely dispersed and separated centrifugally, separated liquid and solid materials are discharged synchronously, and continuous work is achieved. The material continuous negative pressure centrifugal separation drying device is compact in structure, stable and reliable in working, especially suitable for online continuous centrifugal separation of thick liquid materials. Separation and drying can be finished continuously by one time, production cost is greatly reduced, storing of biological activity of material nutrition ingredients is facilitated, and biological product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of separation and drying, and specifically relates to a material continuous negative pressure centrifugal separation and drying device with compact structure, stable and reliable operation, and especially suitable for processing biological products. Background technique [0002] Separation and drying are necessary production processes in the field of chemical technology, especially in the processing of modern biological products, separation and drying are indispensable processes. Centrifugal separation is one of the commonly used separation techniques, which are basically completed under normal pressure. The separation effect is a single centrifugal force, and the separation efficiency is low. Especially for viscous thick slurry materials, the existing centrifugal separation equipment is difficult to achieve the ideal separation effect. Most of the usual drying methods require heating. Excessive heating wil...

AI Technical Summary

Problems solved by technology

In the deep processing of fruit and vegetable products, for example, fruit juice beverages need to be separated and dried. The viscosity of fruit juice slurry is relatively high, and dehydration is difficult. After centrifugal separation, the water content is still high, which brings great difficulties to subsequent drying. Conventional drying requires Heating causes loss of nutrients

Moreover, not only separation and drying are two discontinuous processes, but also the processes of separation and drying cannot be completed continuously, which greatly reduces production efficiency.
