Double Falling Film Evaporator

Double Falling Film Evaporator is composed of two-effect heater, two-effect separator, condenser, heat pressure pump, vacuum and drainage system, circulation or transfer pump, operation platform, electric control cabinet, valve piping and other systems.

  • Product Introduction

Double Falling Film Evaporator Falling film evaporation is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into each heat exchange tube through the liquid distribution and film forming device. Flow up and down. During the flow, it is heated and vaporized by the heating medium on the shell side, and the generated steam and the liquid phase enter the separation chamber of the evaporator together. 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

Double Falling Film Evaporator is composed of two-effect heater, two-effect separator, condenser, heat pressure pump, vacuum and drainage system, circulation or transfer pump, operation platform, electric control cabinet, valve piping and other systems. Because of its special advantages, it is more suitable to be applied to the concentration of materials in the food industry, chemical industry, etc. It is especially suitable for the concentration of heat-sensitive materials, low-temperature temperature concentration shrinkage under vacuum conditions, and intermittent and continuous shrinkage of concentration operations. Construction A double-effect falling film evaporator is composed of following components: – Effect I / Effect II heater – Effect I / Effect II Separator – Condenser – Thermal Vapor Recompressor – Vacuum System – Material Delivery Pump:  material delivery pumps of each effect, condensate discharging pump; – Operation platform, electrical control system, pipelines and valves and etc. Features 1. Double Falling Film Evaporator can operate normally under the lower temperature difference between effects, with less heat loss. 2. The materials are heated for a short period of time and can be operated under lower temperature conditions, which is suitable for the evaporation and concentration of heat-sensitive materials. 3. Good applicability to materials with high foaming and high concentration ratio. 4. The total heat transfer coefficient is high because the materials are in the tube, subject to gravity and high-speed entrainment of secondary steam, in a film-like turbulent flow state. 5. The system has less material in the memory, and it is convenient to adjust the residence time of the material in the system. 6. It can be operated conveniently under automatic or manual conditions, easy to clean and reliable operation. Evaporation capacity: the equipment with different evaporation capacity can be customized according to the needs of customers. -10 -8-9

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.
