Good Reviews of The Live Bloodworm Blister Packaging Machine From Finland

In 2022, a client from Finland found us through Google. He wanted us to manufacture a machine capable of sealing live bloodworms in containers while keeping them alive for a week.

Packaging live organisms was a task we had never encountered before. We analyzed the client's requirements: to seal live organisms in an airtight container and keep them alive for a week. Even for species with low oxygen consumption, respiration is essential. 

Option 1: Inject pure oxygen while sealing. 

Option 2: Use a nutrient solution. 

Option 3: Use breathable packaging materials.

Which option do you think is the most feasible?

To determine the most viable solution, we needed to analyze the biological characteristics of bloodworms: Bloodworms respire through tiny pores on their body surface, absorbing trace amounts of oxygen from water via diffusion in oxygen-deficient environments. They adapt to low-oxygen conditions through hemoglobin-like substances in their bodies, exhibiting facultative anaerobic respiration. This means they can survive in both oxygen-rich and low- or no-oxygen environments.

So, the answer was clear. By preparing a nutrient solution suitable for the survival of bloodworms and injecting oxygen during sealing, we could extend their survival time in sealed containers.

Since the client’s production capacity requirement was not high—20 pieces per minute—we recommended a cost-effective small-scale machine: the GDP-80 blister packaging machine.

Recently, during a follow-up with this client, we discussed the performance of the machine. Possibly due to the unique nature of bloodworms, the machine was not used during hot summer weather but worked well in winter and spring. It will be used again in autumn. The client mentioned that the machine performs very well.

In fact, if the client had not been so cost-conscious and had opted for the touchscreen PLC-controlled model instead of the button-operated version, it would have been even more user-friendly. During the conversation, the client mentioned that they could not use a camera because the button-operated model does not allow easy cursor positioning. This would not have been an issue with the touchscreen model. Of course, if the client has no specific requirements for alignment, not using the camera does not affect production. Once the client begins production, I will showcase the packaging method for live bloodworms（Please bookmark me）.
