Vibro Sifter for Spices

Introduction of vibro sifter for spices

After the spice drying and grinding process, the raw powder must be sieved before packaging to remove any unwanted impurities and oversized materials such as stones. sticks and other coarse and materials, but also gives accurate gradation to improve quality.

Vibro sifter for spices can sieve different types of spices, such as turmeric powder, coriander powder, chili powder, garam masala powder, jeera powder, garlic powder and many more. Since the screen vibrates in multiple planes, the holes of the screen stay clear. An additional anti-blinding system is provided for materials that are difficult to screen and wet. The screen is fully enclosed and dust-free even in the finest sorting.

Application of vibro sifter for spices

Spice manufacturers produce individual spices and mixed spices. But each flavor must go through a screening process. There are many reasons to use a screening machine at this stage.

1. After grinding, the fragrance may contain large pieces of material that have not been ground properly.

2. Formation of clumps or lumps due to humidity.

3. The products stored in the factory may agglomerate.

4. May unknowingly introduce any unwanted impurities, such as metal or plastic parts.

If it is not removed before the packaging process, all these impurities or unwanted contamination will damage the quality of the product.

Working principle of vibro sifter for spices

Vibro sifter for spices divides the fragmented materials with different particle sizes through a single or multi-layer sieve surface with uniformly distributed holes multiple times, and divides them into several different levels to become sieving. After a large number of broken materials with different particle sizes and mixed coarse and fine particles enter the screen surface, only a part of the particles contact the screen surface. Due to the vibration of the screen box, the material layer on the screen is loosened, so that the gap between the large particles is further enlarged. The particles take the opportunity to pass through the gap and transfer to the lower layer or conveyor. Because the gap between small particles is small and large particles cannot pass through, the original disorderly arrangement of particles separates, that is, they are stratified according to particle size, forming an arrangement rule with small particles on the bottom and coarse particles on the top.

Benefits of vibro sifter for spices

1. The machine is made of high-grade stainless steel such as SUS304/316L, and the rubber parts are made of food-grade silica gel, which is colorless, odorless and non-toxic. The inside and outside of the device are mirror polished to prevent contamination of spices.

2. Ultrasonic frequency is applied to the screen to break the surface tension and keep no agglomerated powder in the screen holes, eliminate the blockage of the grid, and reduce the downtime of cleaning the screen.

3. The system can increase the screening capacity by up to 10 times, thereby increasing productivity, while allowing separation accuracy as low as 20 microns (#635 mesh).

4. You can achieve 6 different gradation in a single operation as it can be structured up to 5 decks.
