Pressure cookers are essential kitchen equipment for improving food delivery efficiency and reducing energy costs, and their safety must not be overlooked. A pressure cooker accident may cause serious personal injury, kitchen shutdown, brand reputation damage, and other problems. How to know if a pressure cooker is safe is the first step to avoid potential risks for purchasers. With rich experience in pressure cooker manufacturing, Linkton will analyze five judgment criteria that you must master in detail.
Material safety
The first step to determine whether a pressure cooker is safe is to look at the material. High-quality stainless steel, such as 304 or 316, has good corrosion resistance and high temperature resistance, and is an international standard material that meets food safety standards. Some low-priced products on the market may use 201 or 430 stainless steel, which has a high manganese content, is prone to rust, and releases harmful substances at high temperatures.
It is recommended to check whether the pot body is printed with “SUS304”, “18/8”, or “food grade” and other logos when purchasing, and actively request material test reports, such as SGS or GB4806.9-2016 food contact material certification. All Linkton wholesale pressure cookers use 304 stainless steel and pass the material test of authoritative institutions to ensure that the pot body is still safe and reliable under high pressure and high temperature.
Safety structure design
A qualified commercial pressure cooker must have at least four safety protection mechanisms to ensure that there will be no danger in any extreme use scenario:
Main pressure valve: automatically releases steam when the pressure in the pot reaches the set value (such as 80-100kPa);
Safety valve: activated when the main valve fails to prevent excessive pressure.
Anti-blocking device: effectively filters food residues to prevent vent blockage.
Overpressure exhaust structure: rapid pressure relief in severe abnormal conditions to prevent the pot body from exploding.
Linkton wholesale pressure cookers have passed more than 200,000 safety tests, which is far higher than the industry average, ensuring stable operation under long-term high-frequency use. When purchasing, be sure to understand the product’s pressure relief structure and safety system design drawings to ensure that it is not a simple single valve design.
Sealing and locking lid system
The sealing structure and locking lid system of pressure cookers are often overlooked, but they are precisely the weak points where accidents occur frequently. Inferior sealing rings are prone to aging and deformation under high temperature and high-pressure environments, causing leakage or even the lid being washed open.
It is recommended to give priority to products with FDA-certified food-grade silicone sealing rings and understand their replacement cycle. The sealing rings used by Linkton have a wide temperature resistance range (-40ยฐC to 250ยฐC) and generally do not need to be replaced within 2 years. In addition, advanced locking lid structures (such as Linkton’s patented elastic lock design) can automatically prevent the lid from opening when there is pressure in the pot, eliminating the risk of misoperation from the source.
Testing certification and production standards
When selecting suppliers, buyers must not ignore whether they have professional production and testing qualifications. International certifications such as ISO 9001 and CE are important criteria for measuring whether a manufacturer has systematic quality management capabilities.
Linkton’s full range of pressure cooker products has passed pressure tests, sealing tests, and aging tests, and provides detailed test reports. We conduct simulated pressure tests on each cooker before leaving the factory to ensure that every customer receives a product that has been strictly controlled.
Supplier professionalism
For catering companies, true safety comes not only from the product itself, but also from the professional support of the manufacturer. A reliable pressure cooker manufacturer should have a complete after-sales service system, including operation instructions, common problem response, and technical support.
Linkton has more than 28 years of experience in pressure cooker R&D and export, and provides support to global customers, including after-sales response within 48 hours, video remote guidance, and customized pressure level design, to ensure that your kitchen equipment is safe to use while also achieving efficient operation and durability.
How to know if a pressure cooker is safe? Practical tool: Safety self-check list
To help users better control the safety of pressure cookers, the following is a pressure cooker safety self-check list:
Five inspections that must be done for arrival acceptance
- Appearance: Check whether the pot body and lid have defects such as deformation, cracks, scratches, etc.
- Component function: Test the sealing of the sealing ring, the sensitivity of the safety valve, the firmness of the lid locking structure, etc.
- Material certification: Check the material description and test report to ensure that they are consistent with the purchase requirements.
- Marking integrity: Confirm whether the material logo, safety certification logo, instructions for use, etc., on the product are complete and clear.
- Packaging: Check whether the packaging is intact and whether there are moisture-proof, shock-proof and other protective measures.
Conclusion.
How to know if a pressure cooker is safe? You should not only look at the surface material and price but also have a deep understanding of its structural design, sealing system, certification qualifications and the service capabilities of the manufacturer. Linkton adheres to the “safety-oriented” design concept, provides high-quality pressure cookers from materials, structure to service.
