Sanitary Tubular Quantitative Screw Conveying Equipment – Precision Powder Transport for High-Standard Applications

This equipment belongs to the sanitary-grade tubular quantitative screw conveying equipment category – a specialized model within screw conveying equipment designed for demanding applications.

I. Equipment Type & Core Positioning

This is a food/pharmaceutical-grade tubular screw conveyor (equipped with hopper feed + quantitative discharge unit). It is a "specialized precision model" within screw conveying equipment, primarily used for small-flow quantitative conveying of powders with high requirements for hygiene, sealing, and conveying accuracy – such as pharmaceutical active ingredient powders, food additives, and fine chemical powders.

II. Detailed Structural Analysis Based on Images

Material: All stainless steel (polished surfaces) – compliant with GMP hygiene standards, preventing material residue and contamination.

Shape: Tapered hopper (narrowing at the bottom) – prevents powder accumulation/caking, suitable for fine powders with good flowability.

Auxiliary Design: Handle on top of the hopper for easy operation/cleaning. Side port provided (likely for inert gas inlet to protect oxidation-sensitive powders).

Conveying Core (Tubular Screw):

• Structure: Fully sealed stainless steel round tube – compliant with "dead-spot-free" design of sanitary equipment, completely preventing powder leakage and external dust contamination.

• Screw Element: Built-in screw flight (material should be 316L stainless steel) – suitable for sanitary/corrosion-resistant requirements.

• Connection Method: Quick-connect fittings with the hopper and discharge unit – easy to disassemble for cleaning.

Auxiliary Design:

• Support Legs: Height-adjustable.

• Material Consistency: Entire equipment made of stainless steel – meeting the "easy-to-clean, no residue" requirements of the food/pharmaceutical industries.

III. Typical Application Scenarios

• Pharmaceutical Industry: Batching and conveying of pharmaceutical excipients and active pharmaceutical ingredient powders.

• Food Industry: Quantitative feeding of protein powders and food additives.

• Fine Chemicals: Transfer of high-purity pigment powders and electronic-grade powders for intermediate processes or pre-packaging conveying.
