Vibrating Screen for Fruit and Vegetable Powders

Vibrating Screen for Fruit and Vegetable Powders is a product for grading and removing impurities from powders made from various fruits and vegetables. It features a circular vertical structure and can be flexibly equipped with 1-6 layers of different screen sizes, completing multi-level particle size separation and impurity removal in one pass. The main body of the machine is mostly constructed of 304/316 stainless steel, meeting food hygiene standards. Disassembly and cleaning are simple. Non-standard customization is supported based on factory space, processing capacity, and material characteristics. It is suitable for various fruit and vegetable raw materials such as pumpkin powder, spinach powder, strawberry powder, and mango powder, and can stably sieve out powders of uniform coarseness, removing lumps, fiber residue, and foreign matter.

What is the function of the Vibrating Screen for Fruit and Vegetable Powders?

The Vibrating Screen for Fruit and Vegetable Powders effectively improves the quality of the finished fruit and vegetable powder. Through precise sorting using multiple layers of sieves, the mixed powders are divided into different specifications according to particle size, ensuring that each batch of product has a uniform particle size, avoiding problems such as differences in taste and unstable solubility caused by inconsistent particle size. During operation, it can automatically remove coarse fibers, incompletely crushed fruit pieces, and small impurities mixed in during production, reducing the risk of foreign matter in the finished product. Stable sieving reduces material waste, allowing qualified fine powder to fully pass through the sieve, improving raw material utilization.

How do Vibrating Screen for Fruit and Vegetable Powders work?

Vibrating Screen for Fruit and Vegetable Powders use a vertical vibrating motor as their core power source. Eccentric weights are installed at both ends of the motor. When rotating at high speed, they generate centrifugal force, converting the motor's circular motion into a three-dimensional vibration combining horizontal, vertical, and inclined movements. This multi-dimensional vibration is transmitted to the screen frame and screen mesh, causing the fruit and vegetable powder entering the equipment to exhibit a spiral diffusion motion on the screen surface. After the powder falls into the top inlet, it is continuously thrown, dispersed, and propelled forward by the vibration. Fine powder smaller than the screen mesh size passes through the mesh layer by layer and is discharged from the corresponding outlet; coarse powder and impurities larger than the mesh size move along the screen surface and are separated from the upper outlet.

Structure of Vibrating Screen for Fruit and Vegetable Powders

Vibrating Screen for Fruit and Vegetable Powders mainly consist of five core parts: a dust cover, multi-layer screen frames, a vibrating motor, shock-absorbing springs, and a base. The top dust cover has an inlet to prevent dust overflow and external contamination. The central section consists of multi-layered sieve frames, each with an independent sieve and cleaning device. The sieve frames are securely sealed with clamping rings. A vertical vibrating motor at the bottom provides the excitation force and is the core power source of the equipment. The motor and sieve frames are supported by multiple sets of shock-absorbing springs and connected to the base, effectively isolating vibration and ensuring stable operation.

Optional Types of Vibrating Screen for Fruit and Vegetable Powders

Vibrating Screen for Fruit and Vegetable Powders can be equipped with different screen cleaning structures according to the characteristics of the materials. The two most common types are ultrasonic and scraper types, which are designed for fine powder clogging and high-fiber fruit and vegetable powders that are prone to clumping, respectively, to meet the needs of diverse screening conditions.

Ultrasonic Type: Based on the standard model, an ultrasonic cleaning system is added. Electrical energy is converted into high-frequency mechanical vibration through a transducer, acting directly on the sieve. This effectively suppresses clogging problems caused by sticky and easily agglomerated fruit and vegetable powders such as pumpkin powder and yam powder. High-frequency vibration breaks up powder clumps, allowing fine powder to pass through the screen smoothly, making it particularly suitable for grading ultrafine powders above 300 mesh.

Scraper Type: A rotating scraper or brush device is added above the sieve. During operation, the scraper rotates slowly with the central shaft, continuously cleaning the sieve surface. This vibrating screen effectively breaks up severely clumped and fibrous fruit and vegetable powders, dispersing materials adhering to or bridging the mesh. It's suitable for processing materials with poor flowability and a tendency to clump, improving screening stability and throughput.

What mesh size should you choose for a vibrating screen for fruit and vegetable powders?

The mesh size selection for vibrating screens for fruit and vegetable powders should first consider the material characteristics, finished product requirements, and application scenario. For basic fruit and vegetable powders used in everyday instant drinks and food additives, 80-150 mesh is commonly used, offering a moderate taste and good solubility. For high-end beverages and solid drinks requiring a smoother texture, 200-300 mesh is recommended for a smoother powder. For tableting, granulation, or as an additive carrier, 40-60 mesh coarse powder is preferable for better flowability. For fruit and vegetable powders with high viscosity and sugar content that are prone to clogging, it's recommended to reduce the mesh size by 1-2 levels. For materials with high fiber content, 60-120 mesh is suitable. Higher mesh counts result in finer particles, but also lower throughput and a higher risk of clogging. Selection must be based on a comprehensive consideration of both output and quality.
