In the food industry, what should be paid attention to when choosing metal mesh belts? Material, specifications, surface treatment...   Details   When choosing metal mesh belt materials in the food processing industry, many factors need to be considered comprehensively. The following are some specific selection points:   1. Stainless steel material   SUS304: It has good corrosion resistance and high temperature resistance. It can withstand corrosive substances in most food processing environments, such as grease, acid, alkali, etc. It is also suitable for high-temperature baking, steaming and other processes. It is one of the most commonly used mesh belt materials in the food processing industry.   SUS316L: On the basis of SUS304, more nickel and molybdenum elements are added to make it more corrosion-resistant, especially in an environment containing chloride ions. It has better resistance to pitting and crevice corrosion, and is suitable for food processing scenarios with higher requirements for corrosion resistance, such as marine product processing, dairy product processing, etc.   Carbon steel material: high strength, strong bearing capacity, can withstand heavier food weight and greater impact force, but poor corrosion resistance and high temperature resistance, generally suitable for food processing links that do not require high corrosion resistance and high temperature resistance, and is more commonly used in biscuit baking.   Teflon material: has excellent high temperature resistance and non-stick properties, can be used for a long time at a high temperature of 260°C, food will not adhere to the mesh belt during transportation, easy to clean and maintain, can effectively improve production efficiency and food quality, and is often used for food baking, frying, etc.   2. When choosing a metal mesh belt in the food processing industry, in addition to the material, you also need to pay attention to the following aspects   Clear use requirements and scenarios   To understand the specific process of food processing, such as high temperature baking, low temperature freezing, frying, washing, etc., different processes have different requirements for the high temperature resistance, low temperature resistance, oil resistance, corrosion resistance and other properties of the mesh belt.   For example, bread cooling can use an SR spiral tower mesh belt without a mesh surface, while nuts frying requires a small mesh eyeglass mesh belt.   Mesh belt structure   Common food processing mesh belt structures include chain mesh belt, herringbone mesh belt, spiral tower mesh belt, sidewall mesh belt, etc. Chain mesh belt is suitable for conveying medium-loaded items, spiral mesh belt can be used in quick-freezing equipment and other occasions that require turning, and sidewall mesh belt can prevent materials from slipping.   Mesh belt specifications   The mesh size should be selected according to factors such as the size of the conveyed items and ventilation requirements to prevent food from falling or affecting the processing effect.   The mesh belt width should be determined according to the width and conveying volume of the conveyed items. It is necessary to ensure that the mesh belt can meet the material conveying requirements and match the size of the conveying equipment.   The thickness of the wire diameter affects the strength and load-bearing capacity of the mesh belt. Mesh belts with thicker wire diameters should be selected in places with high load-bearing requirements.   Surface treatment   Metal mesh belts are generally degreased before leaving the factory, and pickled if necessary to achieve the expected conveying effect and hygiene requirements.   Surface smoothness is also important. Choose a smooth and burr-free mesh belt to avoid scratching food or causing accumulation of food residues.   Cleaning and maintenance   Since food production has high hygiene requirements, the mesh belt needs to be easy to clean and can effectively prevent the accumulation of food residues and avoid cross contamination.   Consider the maintenance convenience of the mesh belt, which is convenient for regular inspection, replacement and maintenance to ensure its long-term stable operation.   Cost and benefit   Consider the price, service life, maintenance cost and other factors of the mesh belt, and choose a product with high cost performance. At the same time, pay attention to its impact on production efficiency and product quality. In the long run, high-performance mesh belts may be more economical.

Sintering furnace mesh belts are widely used in sintering processes in industries such as powder metallurgy, ceramics, glass, electronics, and chemicals. These applications include high-temperature sintering of powder metallurgy iron-copper components, high-temperature sintering of electronic components such as thick-film circuits and resistors, and sintering of ceramic products.   Many customers encounter a variety of problems with their sintering furnace mesh belts. The following are some common issues and solutions. Sintering Furnace Mesh Belts   1. Short Mesh Belt Life: Material Matters The high temperature environment within the sintering furnace, as well as the weight and friction of the materials, can easily lead to premature breakage or excessive wear of the mesh belt. Improper mesh belt material selection or improperly adjusted tension during installation can accelerate belt damage. Solution: Appropriate material selection is crucial. Choose materials that are resistant to high temperatures, oxidation, and corrosion, such as SUS310S, AISI314, and nickel-based alloys, based on the sintering furnace's operating temperature and process requirements. During installation, use a suitable tensioning device and regularly check and adjust the belt to ensure proper tension. At the same time, ensure even material distribution and avoid local overload to reduce stress on the mesh belt.   2. Mesh Belt Deformation: Mesh belt specifications and design are crucial. Under the high temperatures and tensile forces of the sintering furnace, the mesh belt is prone to elongation and deformation. Excessive elongation can cause problems with the mesh belt's coordination with other components within the furnace, leading to problems such as deviation and jamming. Solution: During the design phase, fully consider the mesh belt's thermal expansion coefficient and operating environment, and rationally design the mesh belt's dimensions and structure to increase its rigidity and minimize deformation.   3. Cleaning and Maintenance: Regular maintenance is crucial. During the sintering process, material easily adheres to the mesh belt and, at high temperatures, sinters and carbonizes, forming hard lumps that are difficult to clean. This increases cleaning difficulty and maintenance costs. Solution: Establish a regular cleaning schedule to promptly remove carbon deposits, dust, and other impurities from the mesh belt surface to maintain a clean mesh belt. During routine maintenance, inspect the mesh belt's operating condition and promptly repair any minor damage.   Mesh Belt Deviation: The Mesh Belt Adjustment Process is Critical Uneven installation, uneven guide rail wear, uneven material distribution, and deformation of the mesh belt can all cause the mesh belt to deviate during operation. Deviation can cause the mesh belt edge to rub against the furnace wall or guide rails, damaging the mesh belt. It can also lead to uneven material distribution and affect sintering quality. Solution: During installation, strictly calibrate the mesh belt and guide rails to ensure they are parallel. Regularly check the sensitivity and reliability of the deviation correction device to ensure it is fully operational when the mesh belt deviates. Ensure proper material distribution during production to avoid uneven belt force and deviation caused by uneven material weight.   Although the sintering furnace mesh belt is small, it has a significant impact on production. Companies should prioritize its management and maintenance. Through appropriate material selection, proper installation, and meticulous maintenance, they can extend the mesh belt's service life, improve production efficiency, and enhance product quality.
