HCY Belt Vacuum Liquid Continuous Dryer For Malt Extract

Overview

This machine solves a difficult problem in extracting highly concentrated and concentrated and viscous Chinese traditional medicine extract: in the past, the centrifugal spray would damage the thermal-sensitive components and so tend to be sticky to the wall because of its high temperature;and the vacuum oven could not carry out continuous production because it takes long time and lots of energy, and is easy to contaminate and get damp, so both of them could not meet the GMP quality standard.

This machine overcomes many problems mentioned above:its low drying temperature, no loss of effective components, low energy consumption, no contamination, continuous production and automatic control can guarantee the product quality effectively and fully meet the GMP requirements. It is an efficient, energy-saving and new-type drying unit.

This machine is not only applicable to Chinese traditional medicine extract but also suitable for drying such products as polysaccharide medicine, bio-pharmaceutical and coffee. It has a wide application prospect.

Operating principle

Under high vacuum condition, materials are continuously and evenly spreader on the moving guide belt through the spreader and form a thin film. Firstly the guide enters the heating section for low-temperature heating with the temperature controllable within 40℃-180℃ according to material properties, and the moisture in the material will be removed by vacuum after quick flash evaporation due to bubbling; and then materials are delivered to the cooling section for splat cooling by ice water to make them crispy; finally, the materials are collected by the scraper. With automatically controlled discharging, this machine can produce crispy granules of original color and taste. It can carry out continuous automatic production during the whole process and is a piece of ideal equipment for producing Chinese traditional medicine extract, malt extract, starch sugar, plant extract and so on.

Features

1.It meets the GMP standard torealize drying by finishing automatic charging,discharging,grinding and granulating under vacuum condition;

2.The dried products have a wide application scope,they are concentrates from natural medicine and extracts after water extraction,ethanol extraction or other organic solvent extractions and concentration,and generally no supplementary materials are added to the concentrates;

3.The dried granule products have micro-porous structure,good solubility and aromatic odor,and can be formed into tablets or encapsulated directly.Instant (medicinal granules) products can improve their product grade;

4.During operation,the charging rate,material film thickness,running speed of the guide belt and drying time are adjustable according to material properties and drying requirements, so the dryer has great operation flexibility and is suitable for drying various materials;

5.Low-temperature vacuum drying method is adopted for thermal-sensitive materials,with adjustable temperature within 40℃-180℃;

6.It adopts subsection heating structure with preheating section,drying section and cooling section is applicable to mild drying process for all kinds of materials;

7.Continuous discharging starts after drying for 20-80 minutes,with product yield up to over 99%;

8.CIP automatic online cleaning system with various cleaning methods can clean the equioment completely and quickly after drying and meet the GMP requirements;

9.It adopts PLC automatic programming control system to realize high-degree automation,with operating cost being only one third of or even lower than that of its similar drying equipment;

10.It is suitable for large-scale,continuous and automatic operation.
