Inclined Conveyor-Puffed Food Packaging Line

1. Product Overview

The Inclined Conveyor by Shanghai Linguan Equipment Manufacturing Co., Ltd. (Globule Sanitary Conveyor Pty Ltd) is a high-efficiency elevating conveyor purpose-built for puffed-snack packaging lines. It continuously and rapidly transfers potato chips, popcorn, nuts and a wide range of puffed snacks from low-level process stages to high-level discharge points. It solves the most common space conflict on a puffed-snack line: the process flow is short and compact, while the infeed of key machines such as the multihead weigher and the vertical bagging machine sits high above the floor, so the product must be "lifted upward". Plain horizontal conveyors cannot perform this task, and ordinary inclined conveyors struggle with light products such as chips, which tend to slip, roll back and pile up. With a steep working angle of 60° or 80°, food-grade flighting and high-frequency continuous feeding, this machine is the core elevating element of the high-level feeding system.

As the "vertical artery" of the whole packaging line, the working rhythm of the inclined conveyor directly influences the hopper level of the downstream multihead weigher and the continuous running rate of the packaging machine. The whole machine follows the brand philosophy of "Hygiene First · Safety First". It is built on a food-grade stainless steel round-tube open frame with concealed wiring, features no sanitary dead corners, and is fully washable, meeting FSMA hygienic design criteria and the daily sanitation requirements of export-oriented food plants.

2. Position in the Puffed-Snack Packaging Line

On a typical potato-chip or puffed-snack packaging line, the product leaves upstream stages such as frying, seasoning and drying at low level and often in an intermittent flow, while the high-speed weighing and bagging station formed by the multihead weigher and the vertical bagging machine stands on an elevated stainless steel platform. The Inclined Conveyor bridges exactly this gap — receiving at low level, climbing at a steep angle, and discharging at high level:

● The intake end can be connected to the fryer discharge, the seasoning drum discharge or a transfer trolley, and accepts either manual loading or automatic feeding;

● Conveying remains fast and continuous during the climb so that no material gap occurs and the hopper above the multihead weigher always keeps a stable level;

● The discharge end can feed directly into the multihead weigher funnel, the bucket elevator intake or an intermediate buffer hopper, automatically locking onto the downstream rhythm.

Thanks to the steep-angle design, the machine occupies very little floor space and can be arranged close to columns or along the edge of the line, leaving valuable floor area for operators and maintenance aisles.

3. Core Advantages: High-Speed Continuous Inclined Feeding

1. 60°/80° steep angles — less footprint, faster elevation. Puffed-snack plants usually have generous ceiling height but tight floor space. This conveyor supports installation angles of 60° or even 80°, achieving the same lifting height with a much shorter horizontal projection, so continuous high-speed feeding no longer relies on long horizontal buffer sections.

2. Flighting structure prevents light product from falling back. For low-density, drifting materials such as chips and popcorn, the belt is fitted with food-grade flights at pitches of 200 mm / 250 mm / 300 mm. The belt is W550 mm wide with H100 mm low side walls, forming independent "pocket cells". Even at an 80° angle the product is carried securely — no slipping, tumbling or breakage, delivering genuinely continuous high-speed conveying.

3. Adjustable speed that always keeps pace. The drive system uses a SITI/SEW helical gear motor or a motorized drum, controlled by a frequency inverter, so the speed can be matched in real time to the upstream output and the dosing rhythm of the downstream multihead weigher. When the line changes over from chips to popcorn or nuts, only a set-point change is needed — no mechanical modification.

4. Optional online washing unit. Puffed snacks are high in oil, and grease trapped on the flights and belt can breed microorganisms. The optional washing unit, used together with hose-down rinsing, quickly cleans the belt, flights and frame, significantly shortening changeover cleaning time.

4. Structural Design and Hygienic Advantages

The product is offered in three structural forms — slat type (plate type), round-tube type and centre-guide-post type — covering heavy-load, hygiene-first and long-span applications respectively, so the user can choose according to the line layout. The whole machine follows Globule's hygienic design language:

Dead-corner-free round-tube frame

● : an open frame of food-grade stainless steel round tube eliminates liquid trapping and hidden dirt found in square tubes; tube diameter and wall thickness are checked against load and vibration conditions;

Fully washable

● : motors and electrical components are water-protected with concealed cable routing, so the machine can be hosed down directly under high pressure;

Quick disassembly

● : tensioning and reversing mechanisms use tool-free quick-release designs; flights and belting can be removed in minutes for cleaning or replacement;

Complete safety guarding

● : all moving parts are enclosed or guarded; the tension end carries clear safety signage, meeting export machinery safety standards.

6. Integration with the Whole Line

On the puffed-snack packaging line, the Inclined Conveyor normally works together with the bucket elevator, multihead weigher, vibrating feeder, vertical bagging machine, take-off conveyor, metal-detector/checkweigher combo unit, quick-return conveyor, modular belt conveyor and stainless steel platform. It can independently perform short "low-to-high" elevation, or act as the pre-feeder of the bucket elevator, first gathering scattered product into a steady stream before the next stage. Globule supplies unified interfaces and electrical-control protocols for the whole line, ensuring that from the inclined section onward the flow rate and speed fully match the weighing and bagging rhythm downstream — the line never slows down because of the elevating stage.

7. Suitable Products and Conditions

● Potato chips, fabricated chips, shrimp crackers and other sheet-type puffed snacks;

● Popcorn, corn balls, rice puffs and other spherical or irregular puffed snacks;

● Nuts and mixed kernels (with a cushioned intake where needed);

● Other low-density, fragile snack foods requiring gentle handling.
