Helix Types | Hi/Lo portable Helix | Quick auger changeout, and easy to clean.

Batch changeovers and meeting stringent sanitation regulations are easy with the Hi/Lo Helix.

Clean easily. No need for ladders or special tools to clean this conveyor. The electric actuator automatically lowers the auger to an easy-toaccess height. Move from room to room. Fully assembled conveyor fits through standard-height doors. Reach discharge height up to 12 ft (3.66 m).

Loss-in-weight Helix | Move and dose material in one conveyor.

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.

The LIW Helix is available from 3 to 8 inches (7.6 cm to 20.32 cm) nominal case diameter with average capacity ranges from .05 ft3/min to 25 ft3/min (.014 m3/min to .707 m3/min) and a discharge height of 12 feet (3.66 m). Hopper sizes range from 10 ft3 up to 60 ft3 (.283 m3 to 1.7 m3). Hi-Lo option is available for easy raise and lower of the conveyor for cleaning or auger change out. Available with 304 or 316 stainless steel hopper flexible connections, automated and manual discharge. shutoff valves, and more.

Push Helix conveyors | Convey horizontally from a storage point to process.

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.

Available in stainless steel, with auger sizes ranging from 2 to 8 inches (5.08 cm to 20.32 cm). Custom engineered designs are available for more challenging applications and materials, or processes requiring larger capacities. Features a 20:1 turn-down range to accommodate processes requiring a versatile range for conveying material from the load point and into a process or delivery destination.

Poly component Helix conveyors | The light-duty, low-cost quick-ship conveying choice.

Save up to 25% when you choose the P300 Series instead of our 300 Series stainless steel models. Its FDA-approved UHMW polyethylene discharge and hopper lower the price while providing excellent material flow and durable operation.

Convey 0.5 to 1.5 ft3/min (0.014 to 0.042 m3/min) in a completely enclosed conveyor. Meet FDA regulations. Lightweight, easy-to-maintain UHMW polyethylene resists stains and sanitizes easily. Access components for cleaning without using special tools. Quick disconnects make cleaning and servicing easier. Operate safely with the automatic power safety cutoff on the stainless steel grate and sturdy heavy-duty stainless steel frame. Design to your specifications. Use in conjunction with Hapman bag dump stations, dust collectors and bulk bag unloading stations. Optional mounting brackets and supports are also available.

USDA compliant Helix conveyors | USDA dairy grade, sanitary conveyor.

This unit is certified for USDA Dairy Grading applications. When you need to move bulk dairy powders or products in your facility, we can design equipment to meet all of the sanitary conditions that keep your facility food-safe and regulation compliant.

Access internal components quickly, and easily. Quick-release tri-clover connectors let you dismantle the conveyor without tools, so it’s 100% open for cleaning or maintenance in a few minutes. Meet dairy-grade standards on all product contact surfaces. Hapman is the industry’s only flexible screw conveyor manufacturer listed by the USDA for Dairy Grade applications. Ability to sanitize all components to your requirements.

The Hapman Helix Flexible Screw Conveyor is designed to offer customers an economical conveying method that can be applied to most types of dry material conveying applications. The Helix 300 and 400 stainless, and 300 poly models ship within one to two days. For specially designed models, our engineers and manufacturing staff work closely together to deliver your conveyor when you need it.

Options

• Select from a range of hoppers in standard and custom sizes, as well as flanged inlets.
• Available in stainless steel, carbon steel and polyethylene models.
• Optional mobile base provides a discharge height of 12 ft (3.66 m).
• Keep high-moisture or sluggish materials flowing with ribbon and pin agitators.
• Fit under low ceilings with optional right angle drive.
• Hopper-mounted air pads force air along the hopper wall, fluidizing the material for optimal conveying.
• UHMW-PE center core limits the amount of material entering the conveyor, mitigating challenges when conveying very dense material, or highly aerated or fluid material.
• Exclusive quick-release T-handle discharge box allows for tool-less entry to the auger.

Guixens Food Group

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).
