What are the special requirements for rotary evaporator machine in the food industry?

In the food industry, rotary evaporator machines have specific requirements to ensure safety, efficiency and compliance with food processing standards. Here are some key requirements:

1.  Easy to clean and sterilize  : Components that come into contact with food materials should be designed to be easy to clean, sterilize and maintain, with smooth transitions and specific geometric allowances to prevent bacterial growth.

2.  Material compatibility  : The materials used in the construction must be food-grade and resistant to corrosion, especially when handling acidic or alkaline foods, to avoid contamination.

3.  Vacuum system  : The vacuum system should be able to reach and maintain a specific pressure range to reduce the boiling point of the solvent, which is essential for efficient evaporation.

4.  Temperature control  : Accurate temperature control is necessary to prevent overheating and degradation of food nutrients. The system should be able to maintain a stable temperature within a specified range.

5.  Evaporation efficiency  : The rotary evaporator machine must provide a large evaporation surface area to accelerate the evaporation process, which is usually achieved by rotating the evaporation bottle, which forms a thin layer of liquid, thus achieving rapid evaporation.

6.  Safety features  : Safety is crucial, so the  rotary evaporator machine should have overheating protection, ground fault protection and other functions, and may be coated with plastic coating on the glass parts to prevent damage in the event of failure under vacuum.

7.  Chemical inertness  : The  rotary evaporator machine should have a PTFE/ glass liquid channel to ensure chemical inertness and prevent any chemical reaction that may affect the quality of the food.

8.  Life and durability  : The  rotary evaporator machines should be durable, under normal use and maintenance, the design life is not less than 15 years.

These requirements ensure that  rotary evaporator machine in the food industry are not only efficient but also safe, suitable for processing a wide range of foods without compromising quality or safety.
