In the laboratory of Dongguan Jinpai Industry and Trade Co., LTD., post-70s boss Huang Wu is using a gas chromatograph to test the adsorption effect of the new refrigerator deodorized eggs. This 5cm diameter eggshell modeling product can not only absorb the odor of the refrigerator, but also inhibit the breeding of pathogenic bacteria such as E. coli.
First, the birth of products: from user pain points to technological breakthroughs
In the Spring Festival of 2024, Huang Wuming found that his aunt frequently cleaned the refrigerator during a family dinner: "The refrigerator was so tainted that even the breast milk crisper had an odor." The scene inspired his development. After returning to the factory, he retrieved 2000 + user research data and found that the refrigerator odor problem ranked top 3 family pain points.
Technical breakthrough process:
• The first stage: try pure diatomaceous earth adsorption, although it can deodorize but the antibacterial effect is insufficient
• The second stage: adding nano silver ions increased the antibacterial rate to 99.9%, but there was a risk of silver ion migration
• The third stage: the development of "ion locking technology", the silver ion fixed in the diatomaceous earth micropores, through the EU REACH certification
2. Laboratory data: Speak with science
In the test report issued by SGS laboratories, this refrigerator deodorant egg shows amazing performance:
• Adsorption efficiency: the adsorption rate of trimethylamine (fishy smell) is 98.7%, and the adsorption rate of hydrogen sulfide (rancid smell) is 96.2%
• Antibacterial ability: The antibacterial rate of Escherichia coli and Staphylococcus aureus is > 99.9%
• Service life: Deodorized for more than 6 months at 25℃/65% RH
Third, user story: from ordinary treasure mother to bring goods
Ms. Liu, a Shenzhen treasure mother, shared her experience in Tiktok: "I used to clean the refrigerator every week, but now I use deodorized eggs and only wipe it once every two weeks. The most surprising thing is that in the baby food area, even the milk powder can is not damp!" The video received 230,000 likes, driving monthly sales of the product to more than 100,000.
User profile analysis:
• 80% are women aged 25-40, focusing on maternal and child health and home quality
• The re-purchase rate is up to 45%, and the average purchase cycle of users is 3 months
• Little Red book notes more than 5,000, # refrigerator deodorizer topic read more than 100 million
Fourth, the secret behind the production: how to achieve 50,000 pieces per day?
On the intelligent production line, one deodorized egg is produced every 12 seconds:
1. Raw material treatment: Changbaishan diatomite through 8 washes, 3 times magnetic separation, purity of 99.6%
2. Molding process: 3D printing technology is used to achieve uniform 0.1mm microholes on the surface of the eggshell
3. Sterilization packaging: ultraviolet + ozone double sterilization, independent aluminum film packaging to ensure health
Quality control system:
• 50 pieces per batch are randomly selected for drop test (free fall at 0.5 m height without damage)
• Use AI visual inspection to eliminate surface defects
• Passed ISO 22000 food safety management system certification
