A spiral conveyor, also known as a spiral or helical conveyor, is a type of conveyor system that utilizes a continuous spiral-shaped belt or chain to transport materials in a vertical or inclined direction. It is designed to move items between different levels or floors within a facility while maximizing space utilization.
Spiral conveyors find applications in industries such as food processing, packaging, manufacturing, warehousing, and distribution, where efficient vertical or inclined transportation of materials is required.
Vibratory screw conveyors are not only used for vertical conveying, but also for cooling, drying, and temperature control during the conveying process.
Based on cooling methods and structural configurations, vibratory screw conveyors can be divided into the following four common types:
Vibration Spiral Elevator – Common Type
The material is lifted along the spiral groove under the action of vibration, while simultaneously dissipating heat naturally through the air. The open or semi-open structure relies on ambient air for heat dissipation; it is simple in design, low in cost, and suitable for low-temperature or slightly warm materials.
Vibration Spiral Elevator-water Circulation Cooling Type
Cooling water circulates in the jacket or heat exchange plates, removing heat from the material through indirect heat transfer. High cooling efficiency, stable and controllable temperature, suitable for high-temperature materials; in some cases, the temperature range is 200–600°C, requiring a water-cooling system.
Vibration Spiral Elevator-wind cooling type
Air blows across the central column or side air ducts, removing heat from the material surface. Uses fans or blowers, easy to install, but cooling efficiency is lower than water cooling and is significantly affected by ambient temperature.
Vibration Spiral Elevator-wind and Water Circulation Cooling type
Combines water cooling and forced air cooling to maximize heat dissipation efficiency. Highest cooling efficiency; dual heat exchange system, more complex structure, higher cost, suitable for continuous high-temperature processing production lines.
The working principle of a spiral conveyor involves the continuous movement of materials along a spiral-shaped path. Here's a breakdown of the working principle:
Loading: The materials to be transported are introduced onto the conveyor at the entry point, typically at ground level or a lower position. This can be done manually or by integrating the conveyor with other feeding mechanisms or upstream equipment.
Transport: As the spiral conveyor rotates, the materials are lifted or lowered along the spiral path. The shelves or platforms support the materials and move them in a controlled manner. The spiral design ensures a continuous flow of materials, eliminating the need for transfers or changes in direction.
Unloading: At the desired discharge point, usually at an elevated position or a higher level, the materials are unloaded from the conveyor.
Efficient vertical transport
Efficiently transport materials in vertical or inclined positions. They eliminate the need for separate lifts, hoists or inclined conveyors, simplifying material flow and reducing the overall complexity of the handling system.
Improve productivity
Helps increase productivity in material handling operations by providing a continuous flow of material, reducing product handling and transfers, and optimizing space utilization.
Space optimization
Its compact helical shape allows vertical or inclined transport while requiring a smaller footprint than conventional conveyors. This is especially beneficial for facilities with limited floor space or when using multi-story layouts.
Continuous flow
The helical design of these conveyors allows for a continuous flow of material without diversion or change of direction. This smooth, uninterrupted movement reduces the risk of product jams, jams or interruptions in the production process.
Gentle handling
The spiral motion minimizes the risk of product damage or spillage, ensuring safe transport of delicate or fragile items.
Easy to integrate
Can be easily integrated into existing conveyor systems or production layouts. They can be seamlessly connected to upstream or downstream equipment such as feeding mechanisms, sorting systems, packaging machines, etc.

Choosing the right vibrating screw conveyor mainly involves considering four aspects: material temperature, cooling requirements, production capacity, and installation conditions. Combining these with your specific needs will allow you to select the appropriate model. Specific details are as follows:
If the material temperature is below 80℃, strong cooling is not required; ordinary cooling or air cooling is sufficient, meeting the needs while saving money. If the temperature is between 80 and 200℃, cooling requirements are not high; air cooling or water cooling is suitable. If the temperature exceeds 200℃, strong cooling is needed; water cooling is preferred, or a combination of air and water cooling.
If only slight cooling is required and precise temperature control is not necessary, ordinary cooling or air cooling is sufficient, offering a simple structure and cost savings. If precise temperature control is required, choose water cooling for uniform cooling and stable maintenance of the required material temperature. If rapid cooling is desired to improve production efficiency, choose a combination of air and water cooling for both rapid cooling and effective temperature control.
For small-scale production lines with low material handling and low cooling pressure, ordinary cooling or air cooling is the most cost-effective option. For medium-scale production lines with moderate material handling, water cooling can meet the cooling needs of long-term production. For large continuous production lines with high material handling and high cooling pressure, a combination of air and water cooling can ensure stable operation of the equipment over a long period.
The choice depends on the installation conditions, taking into account the site environment, space size, and hygiene requirements. If there is no water supply on site and a water cooling system cannot be installed, air cooling is the preferred choice as it does not rely on a water source and is easier to install. If the site space is small and a separate cooling device cannot be installed, choose a hoist with an integrated cooling system; the integrated design saves considerable space.

Spiral conveyor usually consists of the following main components:
Vibrating platform or trough: It is a structure that holds material and vibrates. The vibration platform is usually made of steel plate or alloy material, which has sufficient rigidity and durability.
Vibrator: Vibrate the vibrating platform or tank by generating vibration force. The vibrator usually consists of an electric motor, an eccentric shaft or a vibration motor, and the vibration frequency and amplitude can be adjusted according to the needs.
Supporting Structure: Supporting structures are usually constructed of steel or other strong material with sufficient strength and stability.
Inlet and outlet: used for the entry and exit of materials. The feed port is usually located at the bottom for material supply, while the discharge port is located at the top or at an appropriate height for material unloading.
Control system: used to control the operation of the vibrator and adjust the vibration parameters. The control system may include components such as electrical control cabinets, sensors, and control panels so that the operator can monitor and adjust the operating status of the vertical vibratory hoist.
Food Processing: For applications such as lifting or lowering food during processing, packaging and distribution. They can transport items such as packaged goods, baked goods, frozen meals, snacks and beverages.
Bottling and Packaging: Transport bottles, cans, jars and other containers vertically. They can be integrated into fillers, labelers and packaging equipment to optimize product flows.
Pharmaceutical and Medical: For vertical transport of bottles, vials, syringes, blister packs and other medical products. They ensure efficient handling and positioning of materials during production and packaging.
Warehousing and Distribution: For vertical movement of various products including boxes, cartons and totes. They optimize space utilization and facilitate efficient material flow between different floors or mezzanines.
What's the difference between air cooling and water cooling?
Air cooling doesn't rely on a water source, offering flexible installation, simple structure, and lower cost. It provides moderate cooling intensity and is suitable for light cooling or scenarios without a water supply, with a relatively gradual cooling rate. Water cooling requires a water supply system, providing high cooling intensity and more uniform and stable temperature control. It has a moderate to high cost and a slightly more complex structure, making it suitable for scenarios requiring strict temperature control or strong cooling, with a faster cooling rate.
Which cooling method is more suitable for high-temperature materials?
For temperatures ≥200℃ requiring strong cooling, water cooling is preferred, or a combination of air and water cooling can be used. If the material temperature is between 80–200℃, both air and water cooling can be flexibly chosen.
Can it be customized?
