Sự miêu tả

The screw of a sugar extruder is a key component in candy production. Its operating principle and design are similar to those of a plastic extruder, but it is optimized for the characteristics of food ingredients such as sugar paste. The following are key technical details:

I. Operating Principle

Feed Section: Sugar paste enters the screw feed section through a metered injection system and is conveyed forward by the screw’s screw threads.
Compression and Plasticization: The screw’s rotation generates shear forces, uniformly plasticizing the sugar paste under high pressure while removing entrained air.
Forming Section: The molten sugar paste is extruded through the die head, cooled and shaped, and then demolded to form a continuous product (such as bonbons or tubes).

II. Structural Features

Screw Design: A single screw is typically used, divided into a feed section, a compression section, and a homogenizing section. The screw pitch and flute depth are adjusted according to the viscosity of the sugar paste.
Die Adaptation: The die head is equipped with a bell-shaped die hole for easy demolding and consistent product specifications. Temperature Control System: External heating and cooling systems precisely control the temperature of the massecuite to prevent burning or over-softening.

III. Application Advantages

Efficient and Continuous Production: Compared to traditional processes, extrusion technology shortens the process and improves raw material utilization, making it suitable for large-scale candy production.

Product Diversity: Can produce a variety of candies, including puffed, filled, and multi-layered ones, such as ready-to-eat cereals or decorative syrups.

IV. Maintenance Tips

Cleaning Requirements: The screw must be regularly disassembled to remove residual massecuite and prevent microbial growth.

Wear Inspection: Use a micrometer to measure the dimensions of the threaded components and promptly replace any cracked or severely worn parts.

Note: Food-grade screws must meet hygienic standards and are typically made of stainless steel or a wear-resistant alloy with a polished surface to reduce massecuite adhesion.
