Sugar Crystals Inclined Screw Conveyor is a device used in sugar factories to convey sugar crystals. It continuously delivers sugar to various stages of the production line while tilting, minimizing crystal loss and quality variations during transport. The conveying capacity can be adjusted according to production scale, typically ranging from 5 to 50 tons per hour, suitable for production rhythms in sugar factories from small to large. The screw diameter is selected based on the conveying capacity, commonly between 100 and 600 millimeters. The length of the inclined conveyor can be adjusted according to the workshop layout, generally from 3 to 20 meters, facilitating the transfer of sugar from one workstation to another. Parts in contact with the sugar are primarily made of 304 stainless steel, with 316 stainless steel used in some high-requirement applications. This prevents contamination of the sugar by metal impurities, resists minor abrasion from the sugar, ensures food hygiene standards, and extends the equipment's lifespan.

Sugar Crystals Inclined Screw Conveyor Parts

The Sugar Crystals Inclined Screw Conveyor's component assembly includes a drive unit, screw blades, inlet, barrel, and outlet. Depending on the characteristics of sugar crystals, the spiral blades can be full-surface, belt, or paddle type. The blade surface is usually polished to reduce friction and ensure smooth conveying. The feed inlet can be designed for end feeding or center feeding to adapt to different feeding methods. The barrel generally uses a closed U-shaped groove or round tube with a smooth inner wall. The tilt angle can be adjusted between 15° and 45° to reduce friction between the sugar and the barrel wall. To prevent sugar clumping, some models have a small stirring device at the feed inlet to gently break up clumps and avoid blockage; some models use a variable pitch design, with a larger pitch at the feed end and a slightly smaller pitch at the conveying end, ensuring stable sugar flow during inclined conveying and preventing backflow of sugar crystals.

Advantages of the Sugar Crystals Inclined Screw Conveyor

The Sugar Crystals Inclined Screw Conveyor offers several advantages when conveying sugar crystals. Sugar crystals are brittle and easily break during handling, affecting their appearance and grade. This conveyor, by adjusting the rotation speed and blade gap of the spiral blades, transports sugar gently, reducing breakage. Sugar is also prone to absorbing moisture and clumping; the enclosed chamber of the equipment isolates the sugar from air, preventing it from melting or clumping due to humidity changes. Furthermore, sugar is prone to slight caramelization or adhesion under friction; the smooth stainless steel surface and angled design prevent sugar from piling up during transport, reducing sugar powder residue and bacterial growth, thus maintaining the integrity and luster of the sugar crystals. Sugar itself is slightly abrasive, but the polished stainless steel surface can withstand this wear, making the equipment less prone to damage over time, easier to maintain, and longer-lasting.

Sugar Crystals Inclined Screw Conveyor Application Scenarios

The Sugar Crystals Inclined Screw Conveyor is a commonly used conveyor in sugar production lines. In the crystallization stage, it smoothly delivers the sugar crystals precipitated in the crystallizer to the centrifugal dehydrator, ensuring a smooth transition between the crystallization and dehydration processes. After centrifugal dehydration, the equipment can also convey wet sugar to the drying equipment, preventing sugar from accumulating or clumping during transport and ensuring drying efficiency. After drying, it can send the finished sugar to the screening equipment for particle grading, or directly to the silo for temporary storage. In the packaging stage, it can send the sugar from the silo to the packaging machine inlet, achieving continuous quantitative feeding. Simultaneously, within the workshop, it can transfer sugar from one silo to another, covering the entire process from crystallization to packaging, making sugar production smoother and more seamless.

The Sugar Crystals Inclined Screw Conveyor is a device for tilting and conveying sugar crystals. During installation, it is generally controlled between 15° and 45°, while maintaining the equipment's horizontal and vertical alignment to prevent sugar backflow, blockage, or abnormal noise. The connection points between the equipment and upstream/downstream processes must be aligned, and the inlet and outlet should be sealed to reduce dust and material loss, while leaving sufficient space for workers to add material, inspect, and clean. With proper installation and layout, the equipment can transport sugar crystals more smoothly, maintaining crystal integrity, supporting stable production line operation, and helping sugar manufacturers improve production efficiency and finished product quality.
