Drained vegetable vibrating screen

Drained vegetable vibrating screen is a screening device used for the preliminary dehydration of washed vegetables, suitable for the assembly line processing of leafy vegetables, root vegetables, or sliced vegetables. Through high-frequency vibration, the separation of water and vegetables is quickly achieved, the screening effect is efficient, and the dehydration rate can reach more than 90%.

The mesh size of the screen is usually between 32-200 mesh (0.075-0.5mm), which can be flexibly selected according to the type of vegetables (such as leafy vegetables, root vegetables), ensuring fine screening while avoiding vegetable damage.

What is the main purpose of the drained vegetable vibrating screen?

The main purpose of the drained vegetable vibrating screen is to efficiently and quickly remove excess water from the surface of vegetables, thereby creating optimal conditions for subsequent food processing, storage, and transportation, while maximizing the quality and integrity of vegetables. Compared with natural draining or manual wiping, the vibrating screen can greatly shorten the draining time and speed up the operation of the entire production line. Removing excess water can prevent bacteria from growing and extend the shelf life of vegetables. For quick-frozen vegetables, reducing water can prevent excessive ice crystals from affecting the taste; for dehydrated vegetables, it can reduce drying energy consumption and improve dehydration efficiency.

What are the disadvantages of the drained vegetable vibrating screen?

Although the drained vegetable vibrating screen is efficient and practical in vegetable processing, it also has some disadvantages. For example, some fragile vegetables (such as tender leafy vegetables) may be slightly damaged, especially when the vibration frequency is too high or the mesh size is improper, resulting in damage to the surface of the vegetables or affected texture.

① Unable to achieve complete drying: The vibrating screen is mainly used to remove most of the moisture on the surface of vegetables, but it cannot achieve deep dehydration or even complete drying like a centrifugal dehydrator or dryer. For products that need to reach very low moisture content (such as dehydrated dried vegetables), other drying equipment is still required.

② Limited effect on specific vegetables: For vegetables with extremely high water content, very soft texture or irregular shape, and easy to stick together (for example, some leafy vegetables are easy to entangle with each other during the drainage process), the vibration drainage effect may not be as expected, and manual assistance or other dehydration methods may still be required.

③ Complex production line requirements: A single vibrating screen may not meet the diverse processing requirements and needs to be matched with other equipment, increasing the difficulty of system integration. For specific application scenarios, it is necessary to reasonably select models and parameters to reduce the impact of these shortcomings.

What can the vegetable vibrating screen for draining be used for

The vegetable vibrating screen for draining is mainly used for the initial dehydration of washed vegetables. It is widely used in clean vegetable processing, central kitchens, quick-frozen vegetable production lines, dehydrated vegetable pretreatment, supermarket fresh food distribution centers and other scenarios. This equipment is often arranged between the washing machine and the air dryer to quickly drain the freshly washed vegetables such as lettuce, Chinese cabbage, spinach, carrot shreds, etc., to reduce the load of subsequent air drying or dehydration equipment.

In central kitchens or group catering companies, the vibrating screen for draining can also be used to drain the cut vegetables briefly to avoid water accumulation when the dishes are packaged, affecting the taste and preservation effect. Some food processing plants also use it to remove moisture from washed fruits, such as apple slices, potato slices, mushrooms, etc., in the assembly line processing links, with automatic feeding and packaging systems to improve the level of production automation.

How to choose a drained vegetable vibrating screen

When choosing a drained vegetable vibrating screen, common screening forms include linear vibrating screens and circular vibrating screens (also known as rotary vibrating screens), which have obvious differences in structure and applicable scenarios.

If the output is large, the vegetables are irregular in shape, and the assembly line needs to be operated automatically, it is recommended to use a linear vibrating screen.

If the output is small, the vegetables are chopped finely, the space is limited, or the materials are frequently changed, a circular vibrating screen can be considered.

The drained vegetable vibrating screen is an indispensable equipment on the vegetable processing line. It uses efficient vibration mechanical action to quickly remove the attached moisture on the surface of the vegetables while gently treating the materials, providing dry or low-water content raw materials for subsequent processing steps, significantly improving production efficiency and product quality. When choosing, it is necessary to determine the specifications and configuration of the equipment according to the specific vegetable type, production capacity requirements, and the connection between the previous and next processes.
