The Loss-In-Weight (LIW) Helix is a fully automated dosing system that is equipped with programmable logic and system integration tie-in functionality. The LIW Helix has load cells built into the hopper base. The flexible screw conveyor carries the material to an elevated point at the required flow rate. The batching functionality of the LIW Helix allows for the measurement and automation of a dosed amount of material while conveying simultaneously.

Hapman’s Push Helix is ideal for batching applications that require controlled horizontal delivery without the need for precision metering or elevated conveying. Ideal for powders, crystals, pellets, friable material, flakes, granules, and more.

Here are just a few examples of the cost-effective ways the Helix is used in practice.
Hapman’s Helix Flexible Screw Conveyor installed at the Guixens Food Group Facility in Tampa, Florida. |
Guixens Food Group, located in Miami and Tampa, Florida, specializes in processing and delivering specialty and imported dry food products to both chain and independent supermarkets. The facility — which conveys eight different products with eight different consistencies — required a very versatile conveyor that could be tailored to each bulk material. The Helix was the conveyor of choice for this facility for two reasons: it offers a variety of interchangeable augers designed to handle specific material characteristics without product degradation or binding; and it is quick and easy to disassemble and sanitize between product changeouts. Because of the variety of products being packaged at the Guixens facility, two types of flat wire augers with different diameters were selected to accommodate the specific material characteristics. The larger diameter screw is used for rice, oatmeal, fine and coarse cornmeal, and ultra-fine corn flour. The smaller screw is used specifically for beans to prevent breakage and ensure high product quality. “I don’t think any other conveyor system could give us the flexibility, ease of cleaning, and simplicity of the Hapman,” said Manuel Guixens, who has been using a Helix in his facilities for many years. “It’s so simple, there’s nothing to go wrong.” |
Popcorn packaging line |
Hapman’s P300 Helix conveyor is shown here as part of an integrated delivery system conveying salt and popcorn, and is used for refilling a Hapman supplied holding hopper above our customers popcorn packaging line. The Helix conveyor operates as an intermittent refill device that is sized to stay ahead of the packaging line. Working off of a high level sensor in the holding hopper, it conveys on demand. This 3” (7.62 cm) conveyor delivers material at a refill rate of about 600 lbs/hour (272 kg/hour). |
