Multiple Effect Vacuum Evaporator

Falling film evaporation is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into the heat exchange tubes through the liquid distribution and film forming device.

  • Product Introduction

Falling film evaporation is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into the heat exchange tubes through the liquid distribution and film forming device. Under the action of gravity, vacuum induction and air flow, it becomes a uniform film. Flow from top to bottom. During the flow process, it is heated and vaporized by the heating medium in the shell side. The generated steam and liquid phase enter the separation chamber of the evaporator. After the vapor and liquid are fully separated, the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator as The medium is heated to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.

Structure and character

Main Feature

1.Because of the whole equipment uniform heating steam heating system, material liquid to liquid film flow evaporation, so it has high heat transfer efficiency, short heating time ,etc major features. If relocation thermal compression pump, more energy saving, low steam consumption and low cooling water circulation. 2.The material flow accelerated down the tube wall pressure evaporation, adapt to the larger material liquid viscosity evaporation concentration. 3.Because the material in each tube formed into membrane evaporation and material liquid heating time is very short, so evaporation and concentration is very good, especially for food larger preserve the nutrition of the food. 4.Under vacuum evaporation process, not only ensure the material requirement, also ensure the requirements of environmental protection, at the same time, greatly reduces the evaporation temperature, plus configuration thermal compression pump, part of the secondary steam by thermal compression pump suction again and raw mix, saves the steam, at the same time by thermal compression pump heating steam spray fog shaped into the shell, steam quickly spread, material liquid heating slowly, so the suitable concentration of thermal sensitive material. 5.Equipment is suitable for evaporation and concentration of foam materials , due to the material liquid into membrane evaporation in the heating tube, which form the gas-liquid separation,at the same time, most of the material liquid at the bottom of the body is siphoned off, only a small part of the material liquid into separator separation, the whole process of material liquid forming no too big impact, greatly reduce the formation of bubbles. 6.For food, evaporating equipment can have sterilization function at the same time, the material after preheating first, and then into the sterilizer, reach more than 94 degrees, hold on 24 seconds, which entered 1st -effect , rapid flash of material, temperature in an instant. 7.Equipment equip with CIP clean system, realize the in-place cleaning, the the whole set of equipment is easy to operate, no dead Angle. 8.Design continuous feeding and discharging. 9.Equipment can equip with automation system, can be configured to realize automatic feed rate control, the heating temperature automatic control, automatic discharging concentration control, automatic cleaning control, can also be equipped with a sudden power failure, failure protection for sensitive material. Other safety, alarm and other automation control.

Application 

Multi-effect Evaporation system is suitable to food and drink processing, pharmaceutical, chemical, biological engineering, environmental engineering, waste recycling and other sectors of high concentration, high viscosity, also with insoluble solids to  low concentration.Multi-effect Evaporation system can widely used in the concentration of the glucose, starch sugar, maltose, milk, juice, vitamin C, maltodextrin and other aqueous solution. And also widely used in liquid waste disposal such as industry field of gourmet powder, alcohol and fishmeal   image004(001)

QA&QC

FAQ:

1. Q : How can customer know the processes of order?

A : We will take photo or video during manufacturing every two weeks to make customer clear about the order. When goods is finished,we will take more detailed photos or video for inspect. You can also come to our factory to inspect by yourself.

2. Q : Do you supply installation equipment in oversea? 

A : Yes, if need, we can also send our installation engineer to your factory to help you do installation and testing. And you need to provides round-trip ticket and accommodation for our engineer. The extra salary of one installation engineer is 200USD/day.

3. Q : How to control quality?

A : All material we use has material certification. Before any piece of equipment leaves CHINZ. It goes through a complete quality and assurance control inspection. This inspection assures your equipment meets all specifications and is in proper working order before it leaves our facility and arrives at your door.

4. Q : What is the shipment schedule?

A : We will send you photographs of your order being loaded into the shipping container at the factory. The shipping container will generally leave port 3-4 days after loading. We will send you a bill of lading and final statement of account within one week of that time. The bill of lading will include the shipping container numbers. You can track your shipping container. Approximately 10 days prior to delivery, we will send you an ETA (Estimated Time of Arrival) notice from the shipping time. Please remember that the listed delivery date is only an estimate, and is subject to port unloading schedules, customs processing, and the dictates of the local delivery truck company. You will be directly contacted by the shipping company’s local truck delivery services approximately 48 hours prior to the date of delivery to schedule a delivery time. If you need to delay the final delivery, there will be a “pull” fee of approximately $100, and a storage fee of approximately $150 per shipping container per day.
