Conveying Tea: Best Conveyors for Powdered & Loose Leaf Tea

Best conveyors for conveying powdered tea or loose leaf tea

Spiroflow experts discuss tea conveying challenges and review considerations for the mechanical conveyors most suitable for conveying tea
Before it is packaged, tea is handled in loose leaf or instant powdered form. Both forms come with challenges that must be overcome via conveyor system design to ensure a final product that is consistent in both flavor and quality. In this article, Spiroflow experts will discuss tea conveying challenges and review considerations for the mechanical conveyors most suitable for conveying tea.

Tea Conveying Challenges

  • Degradation - Friable tea products are prone to degradation, which can cause undesired flavor variations. A conveyor featuring gentle handling will prevent and protect the product from bruising and breaking tea leaves. In addition to impacting flavor, excessive degradation resulting in too fine of a product can cause challenges with separation and blending.
  • Dusting & Safety – Additionally, conveying tea can result in considerable amounts of fine combustible dust which, if not contained, is extremely dangerous – as static buildup from conveying tea leaves increases the risk of explosion. To minimize this risk, select an enclosed conveying system with dust containment features.
  • Abrasion – Tea in leaf form is somewhat abrasive and can lead to higher rates of wear and tear, so selecting a conveyor that will stand up to the job and from a manufacturer that can quickly deliver spare parts will be important.
  • Fast Turnaround During Flavor Changes – Lastly, manufacturers producing flavored teas, both in instant and leaves, may run multiple blends in a single day on the same equipment. Quick clean features of the conveyor to prevent residual flavor transfer between batches – while minimizing downtime – is key.

Flexible Screw Conveyors

Ideal for: Tea blends & flavored teas. A flexible screw conveyor is made up of one moving part – the spiral inside a tube. Because of this, the flexible screw conveyor is a very versatile and low cost conveyor. These conveyors are idea for conveying blends of tea or flavored teas.
Key benefits:
  • Fast cleaning and turnaround between flavored tea batches to prevent residual flavor transfer when running multiple blends in a day (via easy clean quick release flanges)
  • Maintained batch integrity (via constant remixing of the blend via the screw conveyor’s helical motion)

Aero Mechanical Conveyors

Ideal for: Loose Leaf & instant. The aero mechanical conveyor creates an airstream which moves the product up the tubes along with high-speed discs and a rope. This conveyor is a great choice for conveying both instant tea and loose leaf tea. Adding to its benefits, the aero mechanical conveyor runs quietly and with minimal energy requirements.
Key benefits:
  • Total tea dust containment (via airtight operation)
  • Reduced risk of explosion (caused by static build up of combustible tea dust)
  • Gentle handling of friable tea leaves (air pockets in airstream support with gentle conveying)

Cable Drag Conveyors

Ideal for: Loose Leaf & instant, where layout versatility is a requirement. Similar to the aero mechanical conveyor, a cable drag conveyor operates using evenly spaced discs connected by a rope. However, it drags the products along the cable and disc assembly gently at reduced speeds rather than moving it quickly via very fast moving airstream, vacuum or air blasts. Additionally, cable drag conveyors offer conveying in multiple planes and with multiple inlets and outlets while also operating at reduced clearances – for maximum layout versatility.
Key benefits:
  • Best choice for minimal product degradation of tea leaves due to extremely gentle handling (no vacuums, fast moving air blasts, belts or buckets that can potentially cause damage)
  • Total tea dust containment (via contamination free totally-enclosed system)

The Aero mechanical conveyor is cost effective and capable of self-emptying to ensure that everything emptied into the inlet comes out the other end. Customer Requirements Patak’s Foods Ltd. of Leigh, Lancashire in the United Kingdom is a world leader in the production of Indian food. With more than 300 employees, products are distributed internationally to more than 40 countries. The Leigh plant was a significant investment in state of the art food processing facilities which, at 164,000 sq. ft/ 50,000 sq. m, is believed to be the world’s largest Indian food plant. There was a need to improve the transfer of goods from storage to the processing area. * The plant uses 2,700 tons of spices from around the world. * Together with other ingredients, they produce over 1 million snacks and over 1.5 million ready-made meals and 30 million jars of sauce a year. * To achieve this, they are currently working 24/7.

New patented feature for Spiroflow’s iconic flexible screw conveyor
To assist in the breakdown of conglomerated product during conveying, rotating cutter bars have been added to Spiroflow’s iconic flexible screw conveyor Spiroflow’s flexible screw conveyor (FSC), the mainstay of many global conveying operations, now includes a new patented feature. To assist in the breakdown of conglomerated product during conveying, rotating cutter bars have been added to the device, which are powered by the FSC’s drive motor. The addition will not only result in less agglomerated material in the end process, it will also prevent foreign objects from progressing through the conveyor and stalling or damaging the apparatus, thereby creating downtime. Spiroflow has been synonymous with flexible screw conveyors for over 45 years. The brainchild of Michel Podevyn, Spiroflow’s president, who pioneered its early development, the FSC continues to offer a system that’s hygienic, low on installation and maintenance costs and high on efficiency and performance. In explaining the FSC’s early development, Podevyn said: “We tried various systems such as a rigid screw, which deposited metal contaminants

Safe handling and containment solutions of titanium dioxide
As a result of legislation changes made by the EC, Spiroflow advices customers on the safe handling and containment of titanium dioxide (TiO2) powder. TiO2 suspected carcinogen We are taking steps to advise our customers on our range of conveying solutions that are ideally suited to the safe handling and containment of titanium dioxide (TiO2) powder. The move comes as a result of legislation changes made by the European Commission in February 2020, in classifying titanium dioxide (TiO2) as a suspected carcinogen (cat 2) by inhalation. The regulation becomes official on 1 October 2021, meaning that businesses handling TiO2 will need to upgrade the containment of their processes, so that their operators are protected. Even products containing as little as 1% TiO2 will need to be included. Widespread use of TiO2 TiO2 is an inert inorganic compound that is used as a white pigment in many industrial applications. These applications include the manufacture of paints, coatings, printing inks and wall coverings where TiO2 plays a critical role in providing essential product properties: whiteness, covering power, brightness,
