Vacuum Belt Continuous Dryer For Liquid
Liquid Dehydrator / Belt Dryer / Tray Dryer
Overview
The vacuum belt continuous dryer for liquid is designed to solve the problems associated with extracting highly concentrated materials in viscous products. Traditionally, a centrifugal spray dryer would damage the thermally sensitive components and lead to materials sticking to the walls of the dryer. Also, regular vacuum ovens are not ideal for these types of operations because the ovens take long periods of time for drying and require large amounts of energy. This tray dryer is ideal because it features a low drying temperature with excellent sanitary features and it can fully meet GMP requirements.
Application
Plant extracts
Fruit juice concentrates
Pharmaceutical products
Coffee, tea, etc.
Soluble dried malt extract
Bakery products
Meat extracts
Advantages
Controlled testing conditions
Short processing time
Continuous and batch processing
Controlled adjustment of end-product properties including bulk density, color and flavor
Scalability for commercial plants
Work Flow
This drying equipment features a vacuum chamber where a material conveying guide belt (Teflon PTFE) is installed. Materials are distributed continuously on the guide belt after they pass through the continuous vacuum distributor at the top of the machine (adjustable distribution thickness 3mm-30mm). The guide belt conveys the material slowly to the other end while the heating zone (40℃-180℃) below the belt evaporates moisture within the compound. Evaporated moisture is quickly removed by the vacuum system. The compound automatically falls onto the second layer guide belt when it reaches the end. The process repeats until the desired dryness is achieved. When it is finished, materials will fall into the conveying chute at the discharging end where a screw conveyor will deliver it to other processing equipment to be ground, sieved and pulverized.
