Top 4 Considerations When Choosing a Food Vibrating Sieve

Vibrating sieve is widely used in many industries such as food, medicine, chemical industry, etc., and the customary material characteristics and the detailed requirements for vibrating sieve are also different between different industries. Today, we will choose vibrating sieve for food. Refer to the main points for targeted introduction.

From the perspective of the structure of vibrating sieve, it is mainly composed of upper cover, screen frame, screen, transducer for vibrating sieve, vibration motor, shock-absorbing spring, base, etc. Then we mainly purchase vibrating sieve for food. Proceed from these aspects to configure suitable food vibrating sieve.

1. Material selection of food vibrating sieve

The commonly used stainless steel plates for vibrating sieve are divided into 201 and 304 materials. If the food industry chooses, the parts in contact with the material usually use 304 stainless steel or 316L. There are also very strict requirements for the production environment, and the base of the vibrating screen will also be customized to be made of stainless steel 304 material. The parts in contact with the material are not allowed to have any contamination by impurities. The vibrating sieve seals are equipped with food industry hygiene standards, and the material of the food vibrating sieve seals should be made of silicone.

2. Welding process of food vibrating sieve

Since food hygiene is very important, all food processing equipment is required to be easy to clean and sterilize, and the four corners must be free of dust and dirt. When it comes to the welding of vibrating sieve, it is required that the solder joints of each component be free from broken welding and leakage during welding. Welded, burred, and polished to ensure that the surface of the vibrating screen is smooth and scratch-free. In this way, it can be ensured that no powder is hung in the screening process, and there will be no problems such as cross-contamination between materials or unclean cleaning that affect food hygiene and safety.

3. Design points of food vibrating sieve

Considering the thoroughness and simplicity of disinfection and cleaning, the design of the outlet and inlet of the vibrating sieve needs to be designed with a large inclination angle, so that it can be easily sterilized and disinfected in daily maintenance and safeguard food safety.

4. Accessories selection for food vibrating sieve

Regarding the choice of steel above, we recommend that the food industry choose 304 or higher grade stainless steel. But we all know that vibrating sieves also have many rubber-based accessories, such as bouncing balls, sealing rings, etc., so vibrating sieves in the food industry should all be replaced with silicone materials when purchasing these accessories.

The bouncing ball and sealing rubber ring made of silicone are wear-resistant, high-temperature resistant and highly elastic products. They are non-toxic, non-polluting, odorless, non-migrating and have no side effects, so they are often used in industries with high hygiene requirements.

In general, when purchasing vibrating sieves, the food industry should pay special attention to the production qualifications of vibrating screening equipment suppliers, the materials of screening machines, the materials of seals, and the qualifications of manufacturers of ultrasonic screening systems. The manufacture of vibrating screening equipment suppliers can be judged from the size of the enterprise, the number of employees, the configuration of technical personnel, and the configuration of after-sales personnel. If there is time, it is best to conduct on-the-spot investigation; because it is designed and produced for the catering industry, so The whole machine is made of 304 stainless steel.
