Sterilization Process in a Retort Machine

The working process of sterilizing coconut milk using a retort machine usually follows the following steps:

Pr-process: Make sure that the coconut milk product has undergone necessary pr-processed before entering the retort machine, ensure that the coconut milk is free of impurities and clean and hygienic, and pack the coconut milk into appropriate packaging containers, such as bottles or cans or pouches, and seal them intact.

Loading: The packaged coconut milk products are orderly placed on retort baskets or trays, then loaded into the retort cooker.

Preheating: Start the retort sterilizer, which preheats the coconut milk to a specific temperature and pressure, and precisely controls the temperature to prevent damage to the packaging container. It can also kill bacteria and microorganisms in the coconut milk to achieve food safety levels.


Sterilization: When the temperature in the retort sterilizer reaches the set value (e.g. 121°C), the sterilization phase begins. The sterilization time varies from 15 minutes to more than an hour, depending on the product type and size and packaging material.

Throughout the sterilization process, the SUMPOT retort precisely controls temperature and pressure to achieve standardized sterilization and effective sterilization results.

Cooling: After sterilization, the coconut milk product is cooled to the set temperature to prevent over-sterilization and damage to product quality. According to the temperature requirements, the coconut milk can be cooled once or multiple times. Normally, the cooling process can be completed when the temperature point in the center of the container drops below 40 degrees.

Unloading: When the coconut milk product is completely cooled, unload them from retort cooker, check the product container is well sealed and good appearance, then labeling, packaging and transportation are carried out, and the whole coconut milk sterilization process is completed.

Notes on Coconut Milk Sterilization:

Coconut milk sterilization with retort machine has many benefits, but you should also pay attention to the following points:

1. Time control: The time interval from coconut milk filling and sealing to sterilization should be controlled within 1 hour to avoid bacterial growth.

2. Safe loading: Before putting coconut milk into the sterilization kettle, check whether there are people or foreign objects in the kettle, and close the door only after ensuring safety.

3. Pot door safety: After the coconut milk is sterilized, there is residual pressure in the sterilization kettle. At this time, the door should not be opened immediately. Wait until the pressure is naturally released before opening the pot door.

4. Sterilization parameter control: The sterilization temperature, pressure and time should be set strictly in accordance with the specifications and packaging form of the coconut milk product to ensure the expected sterilization effect.
