Quality Control Processing For Producyion Of The Gasket For Plate Heat Exchanger

When producing food grade plate heat exchanger (PHE) gaskets, there are several critical quality control measures that are typically implemented to ensure the highest levels of hygiene and safety. Here are some of the key quality control aspects for food grade PHE gaskets:

Material Verification:

Strict incoming inspection of raw material components (e.g., EPDM, nitrile rubber) to ensure they comply with FDA and other relevant food safety regulations.
Testing for chemical composition, hardness, and other physical properties to validate the material's suitability for food-grade applications.
Dimensional Accuracy:

Precise dimensional control and tolerance management to ensure a perfect fit between the gasket and the PHE plates.
Use of advanced measurement techniques and gauges to verify the dimensions at various stages of production.
Surface Finish:

Meticulous inspection of the gasket's surface finish to eliminate any roughness, crevices, or irregularities that could harbor bacteria or impurities.
Polishing or finishing processes to achieve a smooth, sanitary surface.
Cleanliness:

Stringent cleaning and decontamination protocols during the manufacturing process to remove any potential contaminants.
Controlled environmental conditions, such as clean rooms, to maintain a high level of cleanliness throughout production.
Sterilization:

Terminal sterilization of the finished gaskets, often using gamma irradiation or ethylene oxide treatment, to ensure they are free from microbiological contamination.
Traceability:

Comprehensive lot-level traceability, with detailed records of raw materials, production steps, and quality checks to enable effective recalls if necessary.
Testing and Certification:

Regular testing for compliance with relevant food safety standards, such as FDA, 3-A Sanitary Standards, or European food contact regulations.
Third-party certification to demonstrate the gaskets' suitability for use in food-grade applications.
By implementing these rigorous quality control measures, manufacturers of food grade PHE gaskets can ensure the highest levels of hygiene, safety, and reliability for their products, meeting the stringent requirements of the food and beverage industry.

Heat Exchanger Gasket/Pad for Sondex Plate Heat Exchangers:

1. Heat exchanger gaskets should resist deterioration or damage when exposed to the chemicals present in the fluids being processed. This chemical resistance ensures the longevity of the gasket and the overall reliability of the heat exchanger.
2. Gaskets must be capable of withstanding high temperatures without compromising their integrity. This is crucial for applications where the heat exchanger operates at elevated temperatures.
3. Gaskets may need to comply with industry standards and regulations. This ensures that they meet specific performance and safety criteria for use in various industrial applications.
4. Gaskets can be customized to meet specific requirements of different heat exchanger models. Customization may involve variations in size, shape, and material composition based on the unique needs of the application.
5. To ensure reliable performance, heat exchanger gaskets undergo quality testing during the manufacturing process. This includes checks for dimensional accuracy, material integrity, and sealing capability.

Gasket Material:

Manufacturing process of plate heat exchanger gaskets.

1. The first is the mixing process of rubber compounding, that is, mixing various raw and auxiliary materials according to the formula requirements;
2. The second is the step of forming the rubber material blank, that is, the rubber material is made into rubber strips through extruder equipment;
3. The third is the compression molding process, where the unvulcanized rubber strip is placed into the cavity of the hot mold, the mold is closed for vulcanization, and the rubber sealing gasket is formed in the press equipment;
4. The fourth is post-vulcanization, that is, the molded and vulcanized gasket is placed in an oven in a static state to finally complete the vulcanization;
5. The fifth is finished product inspection, that is, sampling some finished products for finished product testing according to process standards.

Installation method

Plate heat exchanger sealing gaskets can be divided into 3 forms according to the installation method on the heat exchange plates:

1. Direct sticking type: After applying sealant on the sealing gasket, it is directly glued into the installation groove of the heat exchange plate.

2. Plastic nail inlaid type: The heat exchange plate is designed with assembly holes, and rubber nails are designed on the side of the sealing gasket. After the sealing gasket is placed in the installation slot, the rubber nails are embedded in the assembly holes.

3. Snap-on type: There are buckles on the side of the sealing gasket, and the buckles are used to buckle the sealing gasket onto the heat exchange plate.

The sealing gasket uses different types of rubber according to different media and operating temperatures.

Q&A

Q1: Does the gaskets product come with a warranty?

A1: Gasket are consumable accessories, and the replacement cycle is generally determined according to the specific conditions of use by the customer. It is related to the use environment, medium, temperature, etc. Usually we recommend purchasing more for replacement and backup purposes.
