Continuous Evaporative Crystallization System

Hongvadar is advanced in many areas, such as being the corn starch production plant and small scale tomato processing plant.

HVD-CC-T series continuous crystallisation and evaporationsystem is designed and developed by our factory with patent applied.

Core Of Crystallization Process Control

Design enough long crystal time according to crystal characteristics to create an environment conducive to the growth of crystal structure.

Adjust the direction of materials, control the number of microcrystals, realize the whole process control of seed generation, seed growth, elimination of microcrystals, growth of qualified particles, and timely discharge of qualified particles.

Most businesses take crystallization as the process of concentration. It is believed that the concentration reaches supersaturation, the crystal forms naturally, and there is no awareness and measures to control the crystal quality. The control of the crystal purpose is ignored, and the influence of crystallization on separation and drying is not fully considered, which makes the subsequent section treatment more difficult due to the crystallization. Therefore, the purpose of crystallization is to improve the overall yield and product quality and reduce the product production cost.

Characteristics Of Evaporative Crystallization System

Crystallisation and evaporation system/evaporation vs crystallizationsystemis used for products with general requirements on crystal shape and size and can achieve high concentration discharging.

According to the characteristics of materials and the evaporation capacity, continuous crystallisationand evaporation system can be designed as a single-effect or multi-effect evaporative crystallization system.

The unique design of the continuous oscillatory baffled crystallizer, circulating liquid evaporator crystallizerand continuous cooling crystallizercan meet the intermittent crystallization, semi-continuous crystallization, and continuous crystallization system. It can meet the continuous feed, continuous discharge process requirements.

The whole crystallisation and evaporation process system evaporates under the vacuum condition, with relatively low temp, fast evaporation crystallisationspeed, high evaporation concentration, and the relatively high viscosity of the liquid material is not easy to scale or block, which can achieve the maximum crystal ratio under the same energy consumption.

HongVadar relies on professional design, strict production management, the fine processing procedure, provides high efficiency and energy saving equipment system for the customer. The manufacturing factory has passed the international ISO9001 quality system certification, and with the design and manufacturing capacity of pressure vessels. Customers can choose Chinese GB, International ISO, American standard ASME, European standard PED and other standards for equipment design and production according to their needs.
